In contrast, chip- or bottle-grade PET has a higher molecular weight, with its intrinsic viscosity (IV) generally in the ...

Rapid advances in nanotechnology and nucleic acid chemistry are turbocharging pharmaceutical pipelines, speeding the development of treatments for previously incurable medical conditions. These ...

What is Dynamic Light Scattering? Dynamic light scattering (DLS), also known as photon correlation spectroscopy or quasi-elastic light scattering, is a technique used to determine the size ...

A range of different additives and extra layers could change the way a solar cell surface interacts with light, and thus improve its performance. Among these is light scattering, where sunlight hits ...

A fundamental difficulty of working with nanoparticles is that your objects of study are too small for an optical microscope to resolve, and thus measuring their size can be quite a challenge. Of ...

Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two light beams can exist in the same place without influencing each other; they ...

Physicists have discovered that when beams of light interact at the quantum level, they can generate ghost-like particles that briefly emerge from nothing and affect real matter. This rare phenomenon, ...
