A new study at Monash University illustrates how substrates affect strong electronic interactions in two-dimensional metal-organic frameworks.
Materials with strong electronic interactions can have applications in energy-efficient electronics. When these materials are placed on a substrate, their electronic properties are changed by charge transfer, strain, and hybridization.
The study also shows that electric fields and applied strain could be used to “switch” interacting phases such as magnetism on and off, allowing potential applications in future energy-efficient electronics.
The UK @Ministry of Defence #Defence Science and #Technology Laboratory (Dstl) has hosted the UK’s first high-powered, long-range #Laser Directed Energy Weapon (LDEW) trial on its ranges at Porton Down.
The trials involve firing the UK #DragonFire demonstrator at a number of targets over a number of ranges, demanding pinpoint accuracy from the beam director.
The trial improves the UK’s understanding of how high-energy lasers and their associated technologies can operate over distance and defeat representative targets. The ability to deliver high levels of laser power with sufficient accuracy are two of the major areas that need to be demonstrated in order to provide confidence in the performance and viability of LDEW systems.
The programme has developed a UK Sovereign ‘Centre of Excellence’ staffed with experts from multiple fields. LDEW have the potential to provide lower cost lethality, reduced logistical burden and increased effectiveness when compared to other weapon systems – the technology could have a huge effect on the future of Defence operations.
The programme’s specialist industry partners are:
• @MBDA with overall responsibility for the system and have developed the advanced command and control (C2) and image processing capabilities;
In a new study published in the journal PLOS Biology, a team of researchers at University College London posit that it became the “universal currency of life” by way of a little thing known as phosphorylation.
Basically, phosphorylation is the process by which ATP is created. A phosphate molecule is added to another chemical called ADP, and voíla: ATP is born. That same phosphate, as ScienceAlert explains, is then used for another process called hydrolysis, or the reaction of an organic chemical with water that breaks down ATP for use — and that connection with water may be where the secret to ATP’s metabolic dominance lies.
Well, partly. As the scientists discovered in their research, ATP couldn’t rise to the top alone. It needed both water and another phosphorylating molecule, called AcP, to do it. And in fact, it’s likely that ATP actually knocked out AcP as top energy-giving dog.
The new method for harnessing the power of the Sun is “cheaper than traditional fusion approaches.”
U.K.-based startup First Light Fusion is developing its prototype Big Friendly Gun (BFG) in a bid to achieve nuclear fusion without relying on lasers and powerful magnets.

The company recently performed a test-fire of its BFG prototype at its facility in Oxford, a Newsweek report explains. The company’s test campaign could finally unlock the potential of nuclear fusion by using an alternative method to mimic the Sun’s energy production method.
To convert heat into electricity, easily accessible materials from harmless raw materials open up new perspectives in the development of safe and inexpensive so-called “thermoelectric materials.” A synthetic copper mineral acquires a complex structure and microstructure through simple changes in its composition, thereby laying the foundation for the desired properties, according to a study published in the journal Angewandte Chemie.
The novel synthetic material is composed of copper, manganese, germanium, and sulfur, and it is produced in a rather simple process, explains materials scientist Emmanuel Guilmeau, CNRS researcher at CRISMAT laboratory, Caen, France, who is the corresponding author of the study. “The powders are simply mechanically alloyed by ball-milling to form a precrystallized phase, which is then densified by 600 degrees Celsius. This process can be easily scaled up,” he says.
Thermoelectric materials convert heat to electricity. This is especially useful in industrial processes where waste heat is reused as valuable electric power. The converse approach is the cooling of electronic parts, for example, in smartphones or cars. Materials used in this kind of applications have to be not only efficient, but also inexpensive and, above all, safe for health.
A new way of storing renewable energy is providing clean heat through the long Nordic nights.
Other proteins work as well meaning the process can be scaled without interfering with food supplies.
Researchers at Princeton Engineering have found that egg whites can be used to cheaply remove salt and microplastics from seawater, according to a press release by the institution published on Thursday.
The scientists used the food substance to create an aerogel, a lightweight and porous material that can be used in many types of applications, including water filtration, energy storage, and sound and thermal insulation.
Princeton scientists discovered that egg whites can create a filtration process that requires only gravity to operate and wastes no water. They are now looking for other uses for the substance.
The fundamental laws of friction remain a mystery to this day.
Researchers at the NYU Tandon School of Engineering have discovered a fundamental friction law that is leading to the design of two-dimensional materials capable of minimizing energy loss, according to a press release from the institution published on Thursday.
Friction lies behind the invention and development of many of today’s most advanced technologies, however, its fundamental laws remain obscure to this day despite many developments in the field.
NYU Tandon School of Engineering professor of Chemical and Biomolecular Engineering Elisa Riedo and postdoctoral researcher Martin Rejhon have found evidence of a new law of friction.
