"to make vaccines and the temperature-controlled supply chains needed to deliver them"
This paper describes the design and operation of a system used for the accurate control and measurement of temperature in micro-fluidic channels. Ultrasonic transducers are used for both heating and measuring the temperature of fluids inside the channel. Heating is performed by exciting the transducer with a tone burst at a single frequency...
"to improve uptake”
With this technique, the uptake of MNPs in cells can be imaged and quantified directly from the first MNP cell contact, providing information on the dynamics of cellular uptake.
"We focus on better service delivery,”
Focused ultrasound is an early-stage, non-invasive therapeutic technology with the potential to transform the treatment of many medical disorders by using ultrasonic energy to target tissue deep in the body without incisions or radiation.
"transitioning from donor funding in order to sustain the gains"
FRET is the radiationless transmission of energy from a donor molecule to an acceptor molecule. The donor molecule is the dye or chromophore that initially absorbs the energy and the acceptor is the chromophore to which the energy is subsequently transferred.
The gain of electrons is called reduction. Because any loss of electrons by one substance must be accompanied by a gain in electrons by something else, oxidation and reduction always occur together. As such, electron-transfer reactions are also called oxidation-reduction reactions, or simply redox reactions.
The unpaired electron in free radicals makes the atom or molecule unstable. Electrons in atoms "hate" not existing in pairs. An atom with an unpaired electron (a free radical) wants to become stable again, so it quickly seeks out another electron to "steal" from another atom or molecule.
Oxidative stress is an imbalance between free radicals and antioxidants in your body.
An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.
A charge-transfer (CT) complex or electron-donor-acceptor complex is an association of two or more molecules, in which a fraction of electronic charge is transferred between the molecular entities.
Plasmons are the oscillations of free electrons that are the consequence of the formation of a dipole in the material due to electromagnetic waves. The electrons migrate in the material to restore its initial state; however, the light waves oscillate, leading to a constant shift in the dipole that forces the electrons to oscillate at the same frequency as the light. This coupling only occurs when the frequency of the light is equal to or less than the plasma frequency and is greatest at the plasma frequency that is therefore called the resonant frequency.

Oxidative stress plays a critical role in nanotoxicity. Various types of nanoparticles are known to induce oxidative stress by generating intracellular reactive oxygen species (ROS). Cellular uptake of nanoparticles and intracellular metal ion release are important factors for intracellular ROS generation.
A $300 million class action suit has been filed on behalf of the Canadian victims of Cryosan's tainted blood. According to one of the attorneys for the plaintiffs, David Harvey, the suit names Bill Clinton and officials at the Arkansas DOC as defendants
"It was Hilary Clinton that accessed my sex programming. It was Hilary that I was sexually exposed to. It is my experience that she, too, is bisexual, leaning far more towards a homosexual end. The Next Generation In 1980, I was twenty-three and my daughter Kelly was born in Louisiana. She was born right into the CIA's MK Ultra Project. Her level of victimization was much more sophisticated than mine was. Their technology had advanced tremendously by that point. She was subjected to the military/NASA mind control "harmonics" programming as well as the trauma based mind control that I was subjected to."
In an ultrasound context, tissue harmonic imaging is a signal processing technique also termed native harmonic imaging. An ultrasound beam insonates body tissues and generates such harmonic waves from nonlinear distortion during the transmit phase of the pulse‐echo cycle.
Bats navigate and find insect prey using echolocation. They produce sound waves at frequencies above human hearing, called ultrasound.
Periodic high-intensity focused ultrasound modulation of a nanoparticle generates reversible MRI T1 relaxivity changes at the 1.5 mm3 focal point causing periodic T1-weighted signal changes. Fourier analysis extracts signal changes at the modulation frequency, and a modulation enhancement map spotlights the precise region of interest by increasing contrast almost 100-fold.
