Proteins unspool DNA so cells can take on unique properties

Credit: CC0 Public Domain Biologists have long wondered how complex organisms contain a variety of dramatically different types of cells with specialized functions, even though all of those cells are genetically identical. New research reveals how proteins, called pioneer transcription factors, help turn on key genes that give cell types their unique properties and functions. […]

New metamaterial offers reprogrammable properties

Over the past 20 years, scientists have been developing metamaterials, or materials that don’t occur naturally and whose mechanical properties result from their designed structure rather than their chemical composition. They allow researchers to create materials with specific properties and shapes. Metamaterials are still not widely used in everyday objects, but that could soon change. […]

Microfabricated elastic diamonds improve material’s electronic properties

Overcoming a key obstacle in achieving diamond-based electronic and optoelectronic devices, researchers have presented a new way to fabricate micrometer-sized diamonds that can elastically stretch. Elastic diamonds could pave the way for advanced electronics, including semiconductors and quantum information technologies. In addition to being the hardest materials in nature, diamonds have exceptional electronic and photonic […]

New topological properties found in “old” material of Cobalt disulfide

Experimental verification of Weyl nodes in Cobalt disulfide, in comparison to the theoretical prediction. Credit: Princeton Department of Chemistry, Schoop Lab Leading a collaboration of institutions in the U.S. and abroad, the Princeton University Department of Chemistry is reporting new topological properties of the magnetic pyrite Cobalt disulfide (CoS2) that expand our understanding of electrical […]

New Insights from the Magnetic Properties of Fault Rocks

Only a small volume of Earth’s crust is comprised of fault zones, but the processes of strain, deformation, and rupture that occur there have an outsized impact in terms of landscape change, infrastructure damage, and human cost when earthquakes occur. The physical and chemical characteristics of fault rocks, as well as their textures, […]

Germanium telluride’s hidden properties at the nanoscale revealed

The Fermi surface of multidomain GeTe (111) bulk single crystal measured with high-resolution angle-resolved photoemission at BESSY II. Credit: HZB Germanium telluride (GeTe) is known as a ferrolectric Rashba semiconductor with a number of interesting properties. The crystals consist of nanodomains, whose ferrolectric polarization can be switched by external electric fields. Because of the so-called […]

Germanium telluride’s hidden properties at the nanoscale revealed — ScienceDaily

Germanium telluride (GeTe) is known as a ferrolectric Rashba semiconductor with a number of interesting properties. The crystals consist of nanodomains, whose ferrolectric polarization can be switched by external electric fields. Because of the so-called Rashba effect, this ferroelectricity can also be used to switch electron spins within each domain. Germanium telluride is therefore an […]

Material properties for longer-lasting, more efficient solar cells — ScienceDaily

The designers of solar cells know their creations must contend with a wide range of temperatures and all sorts of weather conditions — conditions that can impact their efficiency and useful lifetime. Florida State University Assistant Professor of Chemistry and Biochemistry Lea Nienhaus and former FSU postdoctoral researcher Sarah Wieghold are helping to understand the […]
