Thumb-sized device quickly 'sniffs out' bad breath

No one wants bad breath—not when visiting friends and family, at a job interview, and especially not on a first date. Smelly breath can make things awkward, but it also is a natural warning sign, indicating that serious ...

Nanomaterials with laser printing

In the journal Nature Communications, an interdisciplinary team from the Max Planck Institute of Colloids and Interfaces presents for the first time a laser-driven technology that enables them to create nanoparticles such ...

New strategy improves stability of platinum group metal catalysts

Recently, a group led by Prof. WANG Junhu from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) constructed a novel type of strong metal-support interaction (SMSI) through the melamine/urea ...

Scientists to take a new step in microelectronics' development

Researchers at Peter the Great St. Petersburg Polytechnic University (SPbPU) developed a new approach to determine the best electrode materials composition for solid-state lithium-ion batteries. The results of the study were ...

Green hydrogen: 'Rust' as a photoanode and its limits

Hydrogen will be needed in large quantities as an energy carrier and raw material in the energy system of the future. To achieve this, however, hydrogen must be produced in a climate-neutral way, for example through so-called ...

Catalytic hydrogenation of carbon dioxide to methanol

Efficient conversion of CO2 is strategically significant for alleviating the energy crisis and achieving the goal of carbon neutrality. One promising conversion route is the hydrogenation of CO2 to methanol using a renewable ...
