Modern communication systems often employ optical fibers to carry signals across or between devices. These integrated optics combine more than one function into a single circuit. However, signal transmission requires long optical fibers, which makes it difficult to miniaturize the device. Instead of long optical fibers, scientists have started testing planar waveguides. In the Journal of Applied Physics, investigators report on a laser-assisted study of a type of glass that shows promise as a material for broadband planar waveguide amplifiers.
A team of researchers recently discovered a new aspirin polymorph that’s predicted to dissolve faster than current form I aspirin tablets, which would mean faster pain relief after ingestion. Greater dissolving efficiency also means that each tablet would require less of the compound. Chunhua (Tony) Hu, New York University, will present the painstaking story of aspirin IV alongside its structural definition at the 68th Annual Meeting of the American Crystallographic Association.
Researchers have developed magnetic elastomeric composites that move in different ways when exposed to light, raising the possibility that these materials could enable a wide range of products that perform simple to complex movements, from tiny engines and valves to solar arrays that bend toward the sunlight.
Researchers at Georgia Institute of Technology have created a material derived from crab shells and tree fibers that has the potential to replace the flexible plastic packaging used to keep food fresh.
Many vaccines become ineffective when exposed to room temperature or heat. This challenge can prevent patients from accessing lifesaving immunizations and increase the risk of global pandemics. During the 68th Annual Meeting of the American Crystallographic Association, Jeremiah Gassensmith, University of Texas at Dallas, will describe his lab’s work developing metal-organic framework vaccines. This new biocompatible polymer framework “freezes” proteins inside vaccines. The proteins then dissolve when injected in human skin. This innovation could help health care providers transport and administer vaccines in remote areas with unreliable power.

The one ideal asphalt for all conditions does not exist: Climatic conditions, traffic frequencies and loads place different demands on the pavement. Another challenge: preparing old asphalt so that it can be used for new pavements. Thanks to Empa researchers, the design of the ideal asphalt for every type of road has finally become easier.

Metallic glasses are an exciting research target for tantalizing applications; however, the difficulties associated with predicting how much energy these materials release when they fracture is slowing down development of metallic glass-based products. Recently, researchers developed a way of simulating to the atomic level how metallic glasses behave as they fracture.

The duo reports their findings in the Journal of Applied Physics.

New findings published in Applied Physics Letters help shine light on these materials and indicate potential for optoelectronic and storage applications.
