Powerful graphene hybrid material for highly efficient supercapacitors. A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries.

Usually, energy storage is associated with batteries and accumulators that provide energy for electronic devices. However, in laptops, cameras, cellphones or vehicles, so-called supercapacitors are increasingly installed these days.

Unlike batteries they can quickly store large amounts of energy and put it out just as fast...

An international team of astronomers has investigated a nearby emission nebula and star-forming region dubbed the Cat’s Paw Nebula as part of the B-field In STar-forming Region Observations (BISTRO) survey. Results of this study, presented in a paper published December 24 on arXiv.org, provide essential information about the structure of the object’s complex magnetic field.

At a distance of some 4,240 light years away, the Cat’s Paw Nebula (other designations: NGC 6334, Gum 64) is a high-mass star-forming complex that lies within the galactic plane. The nebula has a form of a filamentary cloud structure spanning 1,000 light years and hosts several star-forming regions.

Observations show that NGC 6334 is dominated by both a dense ridge threaded by sub-filaments, and by two hub-li...

Carrageenans, biologically active polysaccharides isolated from red algae and widely used in the food industry as stabilizers, thickeners, or jelly agents, have an express effect on the immune systems of mice, according to a new study. The research was carried out by scientists from the School of Biomedicine of Far Eastern Federal University (FEFU), Far Eastern Branch of the Russian Academy of Sciences, and Vilnius University. A related article appears in the Journal of Biomedical Materials Research.

“The fact that carrageenan demonstrates immunosuppressive properties in a particular case does not make it g...

Researchers created a novel functional composite of gallium with putty or paste-like physical properties. The composite possesses excellent electromagnetic shielding as well as thermal conductivity. Gallium is a highly useful element that has accompanied the advancement of human civilization throughout the 20th century. Gallium is designated as a technologically critical element, as it is essential for the fabrication of semiconductors and transistors...
