GelucireĀ® 50/13, a macrogol glyceride, was used as a surfactant for the preparation and stabilization of paliperidone-loaded CapmulĀ® GMS-50K matrix-based solid lipid nanoparticles (SLNs).
Electrostatic superlattices have been known to significantly modify the electronic structure of low-dimensional materials. Studies of graphene superlattices were triggered by the discovery of moirƩ patterns in van der Waals stacks of graphene and hexagonal boron nitride (hBN) layers a few years ago. Very recently, gate-controllable superlattices using spatially modulated gate oxides have been achieved, allowing for Dirac band structure engineering of graphene.
Despite these rapid experimental progresses, technical advances in quantum transport simulations for large-scale graphene superlattices have been relatively limited. Here, we show that transport experiments for both graphene/hBN moirƩ superlattices and gate-controllable superlattices can be well reproduced by transport simulations based on a scalable tight-binding model. Our finding paves the way to tuning-parameter-free quantum transport simulations for graphene superlattices, providing reliable guides for understanding and predicting novel electric properties of complex graphene superlattice devices.
Pure blooded Patriot...Sarcastic and Blunt. My opinions are mine and if you don't like what I have to say...go somewhere else.
Interesting...I keep thinking 'anti-gravity'....Not an expert or even claiming to be close to one....but this is very intereting
An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas.
Optical tweezers (originally called single-beam gradient force trap) are scientific instruments that use a highly focused laser beam to hold and move the microscopic and sub-microscopic objects like atoms, nanoparticles and droplets, in a manner similar to tweezers.
Harmonics generation in water droplets of 20 m m typical radius, induced by femtosecond laser pulses at 800 nm. (a) Experimental arrangement. A droplet generator is synchronized with a femtosecond laser so that each droplet is illuminated by a single laser pulse (b) SHG: 800 nm - 400 nm, (c) SFG: 400 nm + 800 nm - 266 nm, and (d) THG: 800 nm - 266 nm (Fig. 1(d) from ref. 45).
Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces.
Microbial aerosol refers to the stable colloidal system of microorganisms floating in air in the state of a single cell suspension or fused with dry solid or liquid particles. If the microorganism is a virus, it is called a virus aerosol (12, 13).
Fog is a colloid since it is a heterogeneous mixture of water, air and suspension particles.
Typical colloidal nanoparticle sols are aqueous or alcoholic solutions/suspensions of oxide nanoparticles with sizes of a few nanometers to tens of nanometers.
Cloud-aerosol interactions in the Earthās atmosphere have several important effects on weather and climate system. First of all, these interactions can change size distribution of aerosols, whose impact on both incoming shortwave and outgoing longwave radiations are evidenced1,2,3. Secondly, more than 50% of Earthās precipitation originates in the ice phase4 and particles that can serve as ice nuclei (IN) are essential in microphysics of cloud and precipitation. In addition, nowadays humans try to modify clouds in order to increase his water resources, and in this context artificial aerosols that contribute in cloud microphysics are desired in cloud seeding. So the aerosol-cloud interactions and consequently their effects on weather, climate and climate change are among important environmental global issues3,4,5.
The process of ice nucleation occurs when small ice crystal embryos form on membrane proteins that act as nucleation sites. These facilitate the aligning of water molecules, which promotes freezing. One ice crystals have formed plants are burdened with a myriad of growth implications and tissue damage.
Hard frost in winter can cause the leaves of hardy evergreen plants to be scorched and turn brown, and may eventually lead to the death of the plant, e.g. bay and pittosporum. The foliage of tender perennials e.g. dahlia and canna may be blackened by the first frost of autumn. Stems usually collapse.
Ice crystals are solid ice exhibiting atomic ordering on various length scales and include hexagonal columns, hexagonal plates, dendritic crystals, and diamond dust.
Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves (hence the name). TMV was the first virus to be discovered. Although it was known from the late 19th century that a non-bacterial infectious disease was damaging tobacco crops, it was not until 1930 that the infectious agent was determined to be a virus. It is the first pathogen identified as a virus. The virus was crystallised by W.M. Stanley.
