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.
A solid’s surface usually melts into a thin liquid layer prior to the melting point. This phenomenon of surface melting occurs in all categories of solids: for example, two ice cubes can fuse at a temperature less than 0°C as the premelted surface water is surrounded inside the bulk at the point of contact and is frozen. Premelting promotes crystal growth, and is vital in geology, metallurgy, and meteorology, such as frost heave, snowflake growth, glacier movement, and skating. As there is a lack of microscopic measurements, the causes of several premelting scenarios and the impact of dimensionality on the premelting phenomenon are poorly understood.
Scientists have successfully integrated hypothetical calculations and sophisticated in-situ microscopy to reveal critical clues about the properties of an advanced energy storage material for use in batteries and supercapacitors. The study was conducted by researchers from Oak Ridge National Laboratory (ORNL) of the Department of Energy (DOE).
