Producing hydrogen and fertilizer at the same time
A research team from the University Alliance Ruhr, Germany, has found a catalyst that can be used to convert ammonia into the energy carrier hydrogen and the fertilizer precursor nitrite. The production of hydrogen and the production of fertilizer ha.....»»
Atomically controlled MXenes enable cost-effective green hydrogen production
A total of 137 countries around the world have signed a "net-zero" climate change agreement to end fossil fuel use and achieve zero carbon emissions by 2050. Hydrogen is being touted as the next green energy source because it emits only water and oxy.....»»
Exploring three-dimensional quantum Griffiths singularity in bulk unconventional iron-based superconductors
Exploration of exotic quantum phase transitions has always been a focus in condensed matter physics. Critical phenomena in a phase transition are entirely determined by the universality class, which is controlled by the spatial and/or order-parameter.....»»
Study introduces lead-coated nickel catalyst for enhanced hydrogen evolution reaction efficiency
In a recent collaboration, a research team developed a hydrogen evolution reaction catalyst that minimizes degradation caused by reverse current in alkaline water electrolysis systems......»»
Nanocarbon catalyst design unlocks new avenue for sustainable fuel additive production
Vehicle exhaust from fossil fuel combustion constitutes a main source of air pollutants like carbon dioxide and carbon monoxide. To mitigate air pollution, researchers are looking into additives to fuels like dimethoxymethane (DMM). But DMM productio.....»»
Single-step procedure synthesizes air-stable, nickel-containing catalyst with safe, cheap materials
Transition metal phosphides have been dreamed of as a potential replacement for noble metal catalysts for a while now. They are cheaper and available in sufficient quantities......»»
Novel two-step electrolysis of water proposed for hydrogen production
A research team led by Prof. Chen Changlun from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, together with collaborators, developed advanced cobalt-doped nickel hydroxide bipolar electrodes and non-noble metal catalyst.....»»
Ancient volcanic eruption not a catalyst for early Homo sapiens cultural innovations, researchers say
An international team of researchers from the Universities of Tübingen (Dr. Armando Falcucci), Siena, and Bologna analyzed the cultural remains left by groups of early Homo sapiens at Grotta di Castelcivita in southern Italy, dating back to before t.....»»
New catalysts enable greener ester synthesis
A new catalyst may well catalyze a shift to greener chemistry. Chemists from Yokohama National University have successfully developed innovative catalysts containing two noble metals that demonstrate remarkable efficiency in ester-producing chemical.....»»
Could we replace Ingenuity with a swarm of robotic bees?
Humans finally achieved controlled flight on another planet for the first time just a few years ago. Ingenuity, the helicopter NASA sent to Mars, performed that difficult task admirably. It is now taking a well-deserved rest until some intrepid human.....»»
New sulfur-free catalyst enables efficient green diesel production
Green diesel, a blend of diesel-grade hydrocarbons derived from renewable oils such as vegetable oils and animal fats, offers a promising alternative to traditional petroleum diesel. With a chemical composition similar to petroleum diesel, it integra.....»»
Researcher says not every exotic species needs to be controlled
Certain invasive exotic species, such as the red swamp crayfish, are harmful to our environment because they nibble on aquatic plants, dig burrows in banks, and transmit crayfish plague to native species. "But there are also non-native fish and crayf.....»»
iPod Tetris game controlled by scroll wheel found on prototype
An unreleased iPod Tetris game has been found on a prototype of a 3rd-gen model, controlled by the scroll wheel … more….....»»
Researchers develop framework for databasing properties of crystal defects
Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in semiconductors like silicon are the backbone of mod.....»»
New catalyst transforms carbon dioxide from industrial emissions into commonly used chemicals
A low-cost, tin-based catalyst can selectively convert carbon dioxide to three widely produced chemicals—ethanol, acetic acid and formic acid......»»
Smartphone addiction is real, and we all probably need to do something about it
If you feel like you're being controlled by your smartphone, don't feel alone — smartphone addiction is a real thing. So, let's talk about it, and how to deal with it.How to dial back your screen timeWe've all done it — we've lost entire days to.....»»
Catalyst search shows how computing can take the guesswork out of chemistry
Imagine synthesizing and then testing over 50 different complex molecules to identify the most effective catalyst for a particular chemical reaction. The traditional approach to developing new catalysts for chemical reactions in this "try it and see".....»»
Researchers show that slow-moving earthquakes are controlled by rock permeability
Earthquakes are the most dramatic and noteworthy results of tectonic plate movement. They are often destructive and deadly, or at the very least physically felt—they're literally groundbreaking geological events. However not all tectonic movement r.....»»
