The generation lasers are short pulse (from tens of nanoseconds to femtoseconds) and high peak power lasers. Common lasers used for ultrasound generation are solid state Q-Switched Nd:YAG and gas lasers (CO2 or Excimers). The physical principle is of thermal expansion (also called thermoelastic regime) or ablation. In the thermoelastic regime, the ultrasound is generated by the sudden thermal expansion due to the heating of a tiny surface of the material by the laser pulse. If the laser power is sufficient to heat the surface above the material boiling point, some material is evaporated (typically some nanometres) and ultrasound is generated by the recoil effect of the expanding material evaporated. In the ablation regime, a plasma is often formed above the material surface and its expansion can make a substantial contribution to the ultrasonic generation. consequently the emissivity patterns and modal content are different for the two different mechanisms.
The frequency content of the generated ultrasound is partially determined by the frequency content of the laser pulses with shorter pulses giving higher frequencies. For very high frequency generation (up to 100sGHz) femtosecond lasers are used often in a pump-probe configuration with the detection system (see picosecond ultrasonics).
Picosecond ultrasonics is a type of ultrasonics that uses ultra-high frequency ultrasound generated by ultrashort light pulses. It is a non-destructive technique in which picosecond acoustic pulses penetrate into thin films or nanostructures to reveal internal features such as film thickness as well as cracks, delaminations and voids. It can also be used to probe liquids. The technique is also referred to as picosecond laser ultrasonics or laser picosecond acoustics.
pick (one's) moment
To thoughtfully and prudently decide the best moment to act.
The absorption of an incident optical pump pulse sets up a local thermal stress near the surface of the sample. This stress launches an elastic strain pulse that propagates into the sample. The exact depth for the stress generation depends, in particular, on the material involved and the optical pump wavelength. In metals and semiconductors, for example, ultrashort-timescale thermal and carrier diffusion tends to increase the depth that is initially heated within the first ~1 ps.
Acoustic pulses are generated with a temporal duration approximately equal to the acoustic transit time across this initially heated depth, in general greater than the optical absorption depth. For example, the optical absorption depths in Al and GaAs are ~10 nm for blue light, but the electron diffusion depths are ~50 and 100 nm, respectively. The diffusion depth determines the spatial extent of the strain pulse in the through-thickness direction.
The main generation mechanism for metals is thermal expansion, whereas for semiconductors it is often the deformation potential mechanism. In piezoelectric materials the inverse piezoelectric effect, arising from the production of internal electric fields induced by charge separation, may dominate.
Photoinduced charge separation is the process of an electron in an atom or molecule, being excited to a higher energy level by the absorption of a photon and then leaving the atom or molecule to a nearby electron acceptor.

It is also possible to generate strain pulses whose shape does not vary on propagation. These so-called acoustic solitons have been demonstrated at low temperatures over propagation distances of a few millimeters. They result from a delicate balance between acoustic dispersion and nonlinear effects.

Would this be because heat causes expansion and therefore more friction? More friction less movement? No expansion=freedom?
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.
Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves. Substances which contract with increasing temperature are unusual, and only occur within limited temperature ranges (see examples below). The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of linear thermal expansion and generally varies with temperature. As energy in particles increases, they start moving faster and faster weakening the intermolecular forces between them, therefore expanding the substance.
Local hyperthermia heats a very small area and is typically used for cancers near or on the skin or near natural openings in the body (e.g., the mouth). In some instances, the goal is to kill the tumor by heating it, without damaging anything else. The heat may be created with microwave, radiofrequency, ultrasound energy or using magnetic hyperthermia (also known as magnetic fluid hyperthermia)
It should not be confused with ablation of small tumors, where higher temperatures (>55°C) are applied with an aim to kill the tumor cells
Many scientists argue that even though viruses can use other cells to reproduce itself, viruses are still not considered alive under this category.
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Examples of liquid crystals can be found both in the natural world and in technological applications. Widespread liquid-crystal displays use liquid crystals. Lyotropic liquid-crystalline phases are abundant in living systems but can also be found in the mineral world. For example, many proteins and cell membranes are liquid crystals. Other well-known examples of liquid crystals are solutions of soap and various related detergents, as well as the tobacco mosaic virus, and some clays.
The chemical composition of magnetite is Fe2+(Fe3+)2(O2-)4. This indicates that magnetite contains both ferrous (divalent) and ferric (trivalent) iron, suggesting crystallization in an environment containing intermediate levels of oxygen. The main details of its structure were established in 1915. It was one of the first crystal structures to be obtained using X-ray diffraction. The structure is inverse spinel, with O2− ions forming a face-centered cubic lattice and iron cations occupying interstitial sites. Half of the Fe3+ cations occupy tetrahedral sites while the other half, along with Fe2+ cations, occupy octahedral sites. The unit cell consists of 32 O2− ions and unit cell length is a = 0.839 nm.[
Iron exists in two oxidation states: the ferrous cation (Fe2+) and ferric cation (Fe3+). Non-haem iron in food is mainly in the ferric state, which is the insoluble form of iron, and must be reduced to the ferrous cation for absorption
When oxygen levels reached significant levels, iron reacted with oxygen, forming ferric oxide.

Magnetic hyperthermia (MHT) utilizing heat generated by magnetic nanoparticles under alternating magnetic field (AMF) is an effective local tumor ablation method but can hardly treat metastatic tumors.
We propose a mechanism for tumor growth emphasizing the role of homeostatic regulation and tissue stability.
We show that competition between surface and bulk effects leads to the existence of a critical size that must be overcome by metastases to reach macroscopic sizes. This property can qualitatively explain the observed size distributions of metastases, while size-independent growth rates cannot account for clinical and experimental data. In addition, it potentially explains the observed preferential growth of metastases on tissue surfaces and membranes such as the pleural and peritoneal layers, suggests a mechanism underlying the seed and soil hypothesis introduced by Stephen Paget in 1889, and yields realistic values for metastatic inefficiency. We propose a number of key experiments to test these concepts. The homeostatic pressure as introduced in this work could constitute a quantitative, experimentally accessible measure for the metastatic potential of early malignant growths.
Self-assembly is the spontaneous organization of smaller subunits to form larger, well-organized patterns. For nanoparticles, this spontaneous assembly is a consequence of interactions between the particles aimed at achieving a thermodynamic equilibrium and reducing the system's free energy.
Thermodynamic equilibrium is an axiomatic concept of thermodynamics. It is an internal state of a single thermodynamic system, or a relation between several thermodynamic systems connected by more or less permeable or impermeable walls. In thermodynamic equilibrium there are no net macroscopic flows of matter or of energy, either within a system or between systems.
Though not a widely named "law," it is an axiom of thermodynamics that there exist states of thermodynamic equilibrium. The second law of thermodynamics states that when a body of material starts from an equilibrium state, in which, portions of it are held at different states by more or less permeable or impermeable partitions, and a thermodynamic operation removes or makes the partitions more permeable and it is isolated, then it spontaneously reaches its own, new state of internal thermodynamic equilibrium, and this is accompanied by an increase in the sum of the entropies of the portions.
Both sensible and latent heats are observed in many processes of transfer of energy in nature. Latent heat is associated with the change of phase of atmospheric or ocean water, vaporization, condensation, freezing or melting, whereas sensible heat is energy transferred that is evident in change of the temperature of the atmosphere or ocean, or ice, without those phase changes, though it is associated with changes of pressure and volume.
The original usage of the term, as introduced by Black, was applied to systems that were intentionally held at constant temperature. Such usage referred to latent heat of expansion and several other related latent heats. These latent heats are defined independently of the conceptual framework of thermodynamics.[3]
When a body is heated at constant temperature by thermal radiation in a microwave field for example, it may expand by an amount described by its latent heat with respect to volume or latent heat of expansion, or increase its pressure by an amount described by its latent heat with respect to pressure.[4]Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling). These names describe the direction of energy flow when changing from one phase to the next: from solid to liquid, and liquid to gas.
"heated at constant temperature by thermal radiation in a microwave field for example"
Microwaves use electricity for it energy source and transmits micrometer electromagnetic waves into the device. These waves then cause the water molecules in the food to move rapidly, producing heat.
Electricity is related to charges, and both electrons and protons carry a charge. The amount of the charge is the same for each particle, but opposite in sign. Electrons carry a negative charge while protons carry positive charge. ... As a result, it is moving electrons that are primarily responsible for electricity.
Piezoelectricity is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat.
Latent heat is the energy absorbed by or released from a substance during a phase change from a gas to a liquid or a solid or vice versa. ... When these gas molecules condense into liquid drops, latent heat is released into the atmosphere which warms the air surrounding the molecule.
A piezoelectric crystal is placed between two metal plates. ... At this point the material is in perfect balance and does not conduct an electric current. Mechanical pressure is then applied to the material by the metal plates, which forces the electric charges within the crystal out of balance.
Acoustic attenuation is a measure of the energy loss of sound propagation in media. Most media have viscosity, and are therefore not ideal media. When sound propagates in such media, there is always thermal consumption of energy caused by viscosity.
An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by "killing" the virus (inactivated vaccine).
Silica particles as a nanoparticulate carrier material for contrast agents have received considerable attention the past few years, since the material holds great promise for biomedical applications. A key feature for successful application of this material in vivo is biocompatibility, which may be significantly improved by appropriate surface modification. In this study, we report a novel strategy to coat silica particles with a dense monolayer of paramagnetic and PEGylated lipids. The silica nanoparticles carry a quantum dot in their center and are made target-specific by the conjugation of multiple alphavbeta3-integrin-specific RGD-peptides. We demonstrate their specific uptake by endothelial cells in vitro using fluorescence microscopy, quantitative fluorescence imaging, and magnetic resonance imaging. The lipid-coated silica particles introduced here represent a new platform for nanoparticulate multimodality contrast agents.
Malignant hyperthermia has been an iatrogenic syndrome which was usually fatal. The syndrome occurs when certain physiologically active compounds act on defective skeletal and cardiac muscle cells. The syndrome consists of a soaring fever, severe acidosis, tachycardia, tachypnea, and usually myoclonic spasms. Cardiac arrhythmias, shock, bleeding disorders, and death soon follow. Malignant hyperthermia has characteristically complicated the administrations of anesthesiologists, but is being triggered by drugs used in other diagnostic and therapeutic activities. This paper reports a fatal case which followed the infusion of iodinated contrast media.
The increased release of epinephrine and the production of fibrin split products seen in an iodinated contrast media reaction suggest certain commonalities between it and a malignant hyperthermia reaction which may be triggered be epinephrine and is complicated by disseminated vascular clotting and bleeding disorders. The potential for successful treatment has greatly improved with the availability of dantrolene. Increased awareness of the syndrome, temperature monitoring, early diagnosis, and rapid treatment should make this malignant disorder less threatening.
Iron oxide nanoparticles, with their superparamagnetic properties, are used in a rapidly expanding number of applications, such as for cell labeling, separation, and tracking; for therapeutic agents in cancer therapy; and for diagnostic agents
Superparamagnetic iron oxide MR imaging contrast agents have been the subjects of extensive research over the past decade. The iron oxide particle size of these contrast agents varies widely, and influences their physicochemical and pharmacokinetic properties, and thus clinical application. Superparamagnetic agents enhance both T1 and T2/T2* relaxation.
T1 (longitudinal relaxation time) is the time constant which determines the rate at which excited protons return to equilibrium. It is a measure of the time taken for spinning protons to realign with the external magnetic field.
This paper describes reversible “on–off” switching of the photoluminescence (PL) intensity of CdSe quantum dots (QDs), mediated by photochromic furylfulgide carboxylate (FFC) molecules chemisorbed to the surfaces of the QDs. Repeated cycles of UV and visible illumination switch the FFC between “closed” and “open” isomers. Reversible switching of the QDs’ PL intensity by >80% is enabled by different rates and yields of PL-quenching photoinduced electron transfer (PET) from the QDs to the respective isomers. This difference is consistent with cyclic voltammetry measurements and density functional calculations of the isomers’ frontier orbital energies. This work demonstrates fatigue-resistant modulation of the PL of a QD-molecule complex through remote control of PET. Such control potentially enables applications, such as all-optical memory, sensing, and imaging, that benefit from a fast, tunable, and reversible response to light stimuli.
Quantum dots (QDs) are a subset of nanoparticles and given their properties, can be used as fluorescent NIR probes, as an alternative to organic dyes.
QDs are typically inorganic semiconductor nanoparticles, with the exception of carbon QDs, with sizes usually below 50 nm. The distinct optical properties observed in these compounds, when compared with their bulk counterparts, are due to the existence of quantum confinement effects. The quantum confinement effects that are observed are directly influenced by the material's composition and physical dimensions.
In bulk semiconductor materials there is a band-gap energy (Eg) that represents the difference between the highest occupied energy state of the valence band and the lowest unoccupied state of the conduction band. When an electron in the valence band absorbs a photon with energy equal to, or higher than Eg, it becomes excited and transitions to the conduction band. This leaves behind an “electron hole.” The negatively charged electron and the positively charged hole form a quasi-particle called an exciton. When the electron relaxes back to the valence band, it annihilates the exciton and may release energy in the form of a photon, with energy lower than Eg (due to energy lost in the transition), in a process called radiative recombination.
In the solid-state physics of semiconductors, carrier generation and carrier recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated. Carrier generation and recombination processes are fundamental to the operation of many optoelectronic semiconductor devices, such as photodiodes, light-emitting diodes and laser diodes. They are also critical to a full analysis of p-n junction devices such as bipolar junction transistors and p-n junction diodes.
The electron–hole pair is the fundamental unit of generation and recombination in inorganic semiconductors, corresponding to an electron transitioning between the valence band and the conduction band where generation of electron is a transition from the valence band to the conduction band and recombination leads to a reverse transition.
photodiode
/ˌfəʊtəʊˈdʌɪəʊd/
noun
a semiconductor diode which, when exposed to light, generates a potential difference or changes its electrical resistance.
There has been much work towards improving infrared photodetectors for telecommunication and spectroscopy, such as indium gallium arsenide (InGaAs) detectors, mercury cadmium telluride detectors, quantum-confined material detectors, etc. However, the performance of these detectors is degraded by factors including difficulty of material growth, requirement of cooling, low quantum efficiencies, or large dark current [1]. On the other hand, silicon (Si) photodetectors can have high detection efficiency, low dark currents, and excellent timing resolution, even at room temperature [2].
To use Si detectors beyond ∼ 1.1 μm, much recent work has focused on parametric frequency processes to upconvert infrared signal above the Si bandgap, which has allowed efficient single-photon-level near-infrared (NIR)-photodetections in Si avalanche photodiodes [3, 4, 5, 6]. It was shown that periodically poled lithium niobate (PPLN) waveguide-based upconversion detectors can achieve a detection efficiency higher than 35% with excess noise as low as 103 counts s−1 [6], outperforming InGaAs detectors, though at the loss of spectral bandwidth. Furthermore, by tuning the pump wavelength and using the phase-matching acceptance bandwidth acting as the frequency selective element, upconversion spectrometers were demonstrated [7, 8, 9, 10].
Demonstrate comes from the Latin word demonstrare, meaning “to point out by argument or deduction.”
To demonstrate a point you must make a valid argument and give examples of why you think it's true.

welding
Ultrasonic welding, for thermoplastic injection moulded components, is a process that uses mechanical vibrations above the audible range. The vibrations, produced by a welding sonotrode or horn, as it is generally known, are used to soften or melt the thermoplastic material at the joint line.
Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.
Nucleate boiling is a type of boiling that takes place when the surface temperature is hotter than the saturated fluid temperature by a certain amount but where the heat flux is below the critical heat flux. For water, as shown in the graph below, nucleate boiling occurs when the surface temperature is higher than the saturation temperature (TS) by between 10 and 30 °C (18 and 54 °F). The critical heat flux is the peak on the curve between nucleate boiling and transition boiling. The heat transfer from surface to liquid is greater than that in film boiling.
Nucleate boiling is common in electric kettles and is responsible for the noise that occurs before boiling occurs. It also occurs in water boilers where water is rapidly heated.
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species (mass transfer in the form of advection), either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system.
Heat conduction, also called diffusion, is the direct microscopic exchange of kinetic energy of particles (such as molecules) or quasiparticles (such as lattice waves) through the boundary between two systems. When an object is at a different temperature from another body or its surroundings, heat flows so that the body and the surroundings reach the same temperature, at which point they are in thermal equilibrium. Such spontaneous heat transfer always occurs from a region of high temperature to another region of lower temperature, as described in the second law of thermodynamics.

A comparison with the case of linearly polar-ized pulses (LP) is made to evidentiate the differenceswith CP and to provide a deeper understanding of “pon-deromotive” (i.e. radiation pressure–dominated) mecha-nisms. This is possible because using CP at normal in-cidence fast electron generation is almost suppressed,18thus related effects (such as TNSA) can be separated bypurely ponderomotive ones.
