With people wanting to use smaller electronic devices, smaller energy storage systems are needed. Researchers of Aalto University in Finland have demonstrated the fabrication of electrochemically active organic lithium electrode thin films, which help make microbatteries more efficient than before. Researchers used a combined atomic/molecular layer deposition (ALD/MLD) technique, to prepare lithium terephthalate, a recently found anode material for a lithium-ion battery.
High-tech metal alloys are widely used in important materials such as the cladding that protects the fuel inside a nuclear reactor. But even the best alloys degrade over time, victims of a reactor’s high temperatures, radiation, and hydrogen-rich environment. Now, a team of MIT researchers has found a way of greatly reducing the damaging effects these metals suffer from exposure to hydrogen.
Prof. Ju-Young Kim (School of Materials Science and Engineering)’s research team developed an ultralight nanoporous gold with high strength. This newly developed material is twice more solid than a regular gold and it is 30% lighter. This research outcome was selected to introduce on the online version of Nano Letters on March 22, 2016.
An international team of scientists led by Artem Oganov, Head of Computational Materials Discovery at MIPT, has proven that technetium carbide does not exist — what previous researchers had obtained was pure technetium that was mistakenly considered as carbide. This is important from the view point of chemistry of transition metal carbides which for many applications are considered as promising substances. The article was published in RSC Advances.
Precise control of an individual particle or molecule is a difficult task. Controlling multiple particles simultaneously is an even more challenging endeavor. Researchers at the University of Illinois have developed a new method that relies on fluid flow to manipulate and assemble multiple particles. This new technique can trap a range of submicron- to micron-sized particles, including single DNA molecules, vesicles, drops or cells.
The Large Hadron Collider (LHC) is a huge particle accelerator, which played a key role in the detection of the elusive particle, Higgs boson. The LHC, buried beneath the Swiss-French border, requires a track extending 27 km for particle acceleration close to the velocity of light before the collision of the particles.
For the first time, polymer scientists from the University of Massachusetts Amherst have discovered the factors that control the final size and shape of chiral filament bundles that self-assemble into different architectures. The research team, which included Greg Grason, Isaac Bruss and Douglas Hall, along with Justin Barone from Virginia Tech, reported the experimental results that support their novel model. The study has been reported in the current issue of the Nature Materials journal.
The Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) has developed a new processing technique for two-dimensional (2D) electronic devices. This new technique has the potential to reduce the power consumption of the devices, and to increase their efficiency and mechanical flexibility.
Heterostructures (referred to as Van der Waals {VdW}) are attracting a great deal of attention due to their diverse physical and chemical properties. A VdW heterostructure is assembled by stacking two or more different 2D semiconducting crystals on top of each other.
Arthritis and sport-related injuries are a common occurrence in the elderly, athletes and others who experience severe pain as a result of damaged cartilage tissues. Scientists have now demonstrated how to use 3-D bioprinting to create cartilage tissues that could resolve this issue.
