Biologists highlight the risks posed to aquatic organisms when nanoparticles ‘transform’ on contact with water and as they pass from water to sediment and then into sediment dwelling organisms.

A team of physicists and chemists has studied the interaction of light with tiny glass particles. The relationship between strong laser pulses and glass nanoparticles is a special one — one that could influence medical methods, as scientists have discovered.

Scientists devised a new way of assembling ordered crystals made of nanoparticles. In this process, nanoparticles in the shape of cubes, octahedrons, and spheres coordinate with each other to build structures. The shapes are bound together by complementary DNA molecules on each type of particle.

Scientists have developed a new technique for finding quantum dots. A quantum dot should produce one and only one photon — the smallest constituent of light — each time it is energized, and this characteristic makes it attractive for use in various quantum technologies, such as secure communications. However, the trick is in finding them.

Scientists have created a solid-state memory technology that allows for high-density storage with a minimum of errors.

A new microscope will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and beneath the surface.

People with diabetes mellitus often suffer from impaired wound healing. Now, scientists have developed antibacterial nanofibres of cellulose acetate loaded with silver that could be used in a new type of dressing to promote tissue repair.

An emerging technique called fluctuation X-ray scattering (FXS) could provide much more detail about a protein’s molecular structure than traditional solution scattering. But a major limitation for FXS has been a lack of math methods to efficiently interpret the data. That’s where new math comes in.

A new method to extract more efficient and polarized light from quantum dots (QDs) over a large-scale area has been developed by researchers. Their method, which combines QD and photonic crystal technology, could lead to brighter and more efficient mobile phone, tablet, and computer displays, as well as enhanced LED lighting.

The chemical reactions that make methanol from carbon dioxide rely on a catalyst to speed up the conversion, and scientists identified a new material that could fill this role. With its unique structure, this catalyst can capture and convert carbon dioxide in a way that ultimately saves energy.
