The RoHS concept (Restriction of the use of certain Hazardous Substances) since 2006, requires that many electrical and electronic equipment must no longer contain a concentration by atomic weight of more than 0.1% of Pb, Me, Cr (hexavalent) etc…

For the last few decades, battery research has largely focused on rechargeable lithium-ion batteries, which are used in everything from electric cars to portable electronics and have improved dramatically in terms of affordability and capacity. But nonrechargeable batteries have seen little improvement during that time, despite their crucial role in many important uses such as implantable medical devices like pacemakers.

Nanoparticles, or tiny molecules that can deliver a payload of drug treatments and other agents, show great promise for treating cancers. Scientists can build them in various shapes with different materials, often as porous, crystal-like structures formed by a lattice of metal and organic compounds, or as capsules that enclose their contents inside a shell. When injected into a tumor, these particles can release treatments that attack cancer cells directly or complement other treatments like immunotherapy and radiation.

Researchers at Johannes Gutenberg University Mainz (JGU) are pursuing a completely new and unconventional strategy to improve the way data can be processed and – in particular – stored. Together with their partners at the Hebrew University of Jerusalem, they have been granted funding by the Carl Zeiss Foundation (CZS). The project of this interdisciplinary team is among a total of five projects – all at early stages and considered to be especially innovative – to be funded through the new CZS Wildcard program. The team members, based in Mainz and Jerusalem, have come up with the idea of bringing together two different forms of chirality to develop new data storage systems that are faster, smaller, and more efficient than those currently available.

In a study published in Nature (“Functional CeOx nanoglues for robust atomically dispersed catalysts”), a research team led by Prof. ZENG Jie from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences and international collaborators developed a novel “nanoglue” strategy to stabilize atomically dispersed metal catalysts.

The energy and transportation sector often make use of different kinds of fluid machinery, including pumps, turbines, and aircraft engines, all of which entail a high carbon footprint. This result mainly from inefficiencies in the fluid machinery caused by flow separation around curved surfaces, which are typically quite complex in nature.

A Ludwig Cancer Research study has developed a novel nanotechnology that triggers potent therapeutic anti-tumor immune responses and demonstrated its efficacy in mouse models of multiple cancers. Led by Co-director Ralph Weichselbaum, investigator Wenbin Lin and postdoctoral researcher Kaiting Yang at the Ludwig Center at Chicago, the study describes the synthesis, mechanism of action and preclinical assessment of the nanoparticle, which is loaded with a drug that activates a protein central to the efficient induction of anti-cancer immunity.

A team of researchers has discovered a new mechanism to stabilize the lithium metal electrode and electrolyte in lithium metal batteries. This new mechanism, which does not depend on the traditional kinetic approach, has potential to greatly enhance the energy density — the amount of energy stored relative to the weight or volume — of batteries.

Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering.
Their discovery has recently been published in the journal Nature (“Photonic topological insulator induced by a dislocation in three dimensions”).
