[Innovation] – Codex International fully committed to « Lead free materials” 7 novembre 2022

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…

[Nano-Technology] – New materials could enable longer-lasting implantable batteries 2 novembre 2022

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.

[Nano-Technology] – Advanced nanoparticles provide new weapon to fight difficult cancers 28 octobre 2022

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.

[Nano-Technology] – Nanoglues stabilize metal atoms for catalysis 26 octobre 2022

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.

[Thin-Films] – Multidirectional MEMS thin-film sensor improves efficiencies of industrial-scale fluid machinery 19 octobre 2022

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.

[Nano-Technology] – 2D Nanosheets as anodes in Li-ion batteries 12 octobre 2022

As the electric vehicle (EV) industry is advancing, so are the efforts in the research and development of superior lithium (Li)-ion batteries to power these vehicles. Exploring and expanding rapid charge-discharge technology and extended battery life are critical challenges in their development. A few factors, such as the diffusion of Li ions, characteristics of the electrode-electrolyte interface, and electrode porosity, can help overcome these issues achieve extreme fast charging and ultralong life.

[Nano-Technology] – Novel nanotechnology triggers potent therapeutic anti-tumor immune responses 5 octobre 2022

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.

[Nano-technology] – Researchers design next-generation electrolytes for lithium batteries 1 octobre 2022

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.

[Thin-Films] – Researchers still fail to print thin-film transistors with metal oxides onto heat-sensitive materials 29 septembre 2022

The bar was undoubtedly set high: In the research project Functional Oxides Printed on Polymers and Paper – FOXIP for short – the goal was to succeed in printing thin-film transistors on paper substrates or PET films. Electronic circuits with such elements play an important role in the growing Internet of Things (IoT), for example as sensors on documents, bottles, packaging … – a global market worth billions.
