Electrochemical synthesis of formate from carbon dioxide using a tin/reduced graphene oxide catalyst
Decreasing the emission and efficient utilization (fixation) of carbon dioxide (CO2) are worldwide issues to prevent global warming. Promotion of the use of renewable energy is effective in reducing CO2 emissions. However, since there are large time-.....»»
Tiny currents may impact vital ocean food source
Copepods are tiny crustaceans about the size of a grain of rice, but they are one of the most important parts of the Earth's aquatic ecosystems. Their behavior and interaction with the environment, however, remains a relative mystery. Now, a recent p.....»»
One degree of global warming causes a 50% increase in population displacement risk
A new study shows that if the population were fixed at current levels, the risk of population displacement due to river floods would rise by ~50% for each degree of global warming. However, if population increases are taken into account, the relative.....»»
Taking microelectronics to a new dimension
Metallic microstructures are the key components in almost every current or emerging technology. For example, with the next wireless communication standard (6G) being established, the need for advanced components and especially antennas is unmet. The.....»»
Modification of graphene using laser light
Graphene is an exciting new material, which has been characterized as a 'wonder material' because of its excellent properties. Graphene gained widespread attention in 2010 when the Nobel Prize in physics was awarded to researchers who discovered it......»»
These undergraduates left university to build Flux, a payments startup now in YC
Traditional remittance companies, while necessary, currently have two flaws in speed and exorbitant fees. It can take a long while (days to weeks) for money sent from an immigrant in the U.S. to reach a relative in Nigeria. The fees charged depend on.....»»
Method for determining electron beam properties could help future ultraviolet, X-ray synchrotron light sources
The detected intensity from two coherent point-like light sources depends on their relative positions. It is a well-known phenomenon called optical interference. In general, the intensity can range from zero (destructive interference) to some maximum.....»»
Research finds surprising electron interaction in "magic-angle" graphene
In 2018, physicists showed that something interesting happens when two sheets of the nanomaterial graphene are placed on top of each other. When one layer is rotated to a "magic angle" of around 1.1 degrees with respect to the other, the system becom.....»»
Acoustic graphene plasmons study paves way for optoelectronic applications
KAIST researchers and their collaborators at home and abroad have successfully demonstrated a new methodology for direct near-field optical imaging of acoustic graphene plasmon fields. This strategy will provide a breakthrough for the practical appli.....»»
Scientists plumb the depths of the world"s tallest geyser
When Steamboat Geyser, the world's tallest, started erupting again in 2018 in Yellowstone National Park after decades of relative silence, it raised a few tantalizing scientific questions. Why is it so tall? Why is it erupting again now? And what can.....»»
The importance of international standards for the graphene community
NPL, in collaboration with international partners, has developed an ISO/IEC standard, ISO/TS 21356-1:2021, for measuring the structural properties of graphene, typically sold as powders or in a liquid dispersion. The ISO/IEC standard allows the suppl.....»»
How good metals go bad: Discovery explains unexpected properties of exotic metallic compounds
New measurements have solved a mystery in solid state physics: How is it that certain metals do not seem to adhere to the valid rules?.....»»
Universal sequence of Chern insulators in superconducting magic angle graphene
Scientists from ICFO, Princeton and NIMS have discovered a full sequence of symmetry-broken Chern insulators that are induced by strong correlations in magic angle graphene. The study has been published in Nature Physics......»»
Wider horizons for highly ordered nanohole arrays
Scientists from Tokyo Metropolitan University have developed a new method for making ordered arrays of nanoholes in metallic oxide thin films using a range of transition metals. The team used a template to pre-pattern metallic surfaces with an ordere.....»»
Graphene nanoparticles and their influence on neurons
Effective, specific, with a reversible and non-harmful action: the identikit of the perfect biomaterial seems to correspond to graphene flakes, the subject of a new study carried out by SISSA—International School for Advanced Studies of Trieste, Ca.....»»
Research predicts the high-temperature topological superconductivity of twisted double-layer copper oxides
Two-dimensional (2D) materials, such as graphene or transition metal dichalcogenides, can sometimes be assembled into bilayers with a twist between individual layers. In recent years, many researchers have been investigating the properties of these t.....»»
By adding strain, researchers improve metallic glass
Metallic glasses—materials with the strength of metal, but moldable like plastic—are being developed for a broad range of applications. Controlling the formation of metallic glasses and their resulting properties in bulk form, however, remains a.....»»
Sea level rise up to four times global average for coastal communities
Coastal populations are experiencing relative sea-level rise up to four times faster than the global average—according to new research from the University of East Anglia......»»
Samsung"s Isocell 2.0 pushes mobile camera technology forward
