Researchers develop new approach for efficient data processing

A new approach to IT technologies: The use of spin waves as data storage may one day allow computers and smartphones to compute more efficiently and reliably. This is the conclusion reached by a team of researchers from Martin Luther University Halle-Wittenberg (MLU) and Lanzhou University in China based on simulations for spin waves in structured materials. The study was published in the journal "npj computational materials".

Spintronics: Physicists develop miniature terahertz sources

Researchers at Martin Luther University Halle-Wittenberg (MLU) and Freie Universität Berlin have developed a new, simple approach for generating terahertz radiation. Strong optical laser pulses enable terahertz electromagnetic fields to be generated directly at a specific point. The team has published its findings in the journal "ACS Applied Nano Materials". Potential applications for terahertz radiation are wide ranging - from materials testing to communications and security technology.

Researchers spot a “golden” bear while studying endangered spectacled bears in Peru

The number of spectacled bears in Peru might be larger than suspected, a new study in "URSUS" suggests. A team of researchers from Gothenburg University, Martin Luther University Halle-Wittenberg (MLU) and Stony Brook University studied the population of the endangered species in Northern Peru. By identifying individuals through facial patterns, they were able to estimate the population density in the area and identify an unknown hotspot. Intriguingly, the researchers also observed the first "golden" bear.

Scientists develop alternative cement with low carbon footprint

Researchers at the Martin Luther University Halle-Wittenberg (MLU) in Germany and the Brazilian University of Pará have developed a climate-friendly alternative to conventional cement. Carbon dioxide (CO2) emissions can be reduced during production by up to two thirds when a previously unused overburden from bauxite mining is used as a raw material. The alternative was found to be just as stable as the traditional Portland cement.

Solar cells: Layer of three crystals produces a thousand times more power

The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. This has been revealed in a study by researchers at Martin Luther University Halle-Wittenberg (MLU). They achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which they alternately placed on top of one another. Their findings, which could significantly increase the efficiency of solar cells, were published in the journal "Science Advances".
