Researchers managed to make homogenous cylindrical objects completely invisible in the microwave range. Contrary to the now prevailing notion of invisibility that relies on metamaterial coatings, the scientists achieved the result using a homogenous object without any additional coating layers.
Scientists have uncovered the first evidence of an unusual quantum phenomenon - the integer quantum Hall effect - in a new type of film, called a 3D topological insulator. In doing this, they demonstrated that 'surface Dirac states' - a particular form of massless electrons - are quantized in these materials, meaning that they only take on certain discrete values.
Researchers have demonstrated a promising new way to increase the effectiveness of radiation in killing cancer cells. The approach involves gold nanoparticles tethered to acid-seeking compounds called pHLIPs.
A paper-based test enables a rapid analysis of whether a compound - in this case, morphine - is present in a given sample. Possible future applications of the developed test include drug testing at workplaces and in connection with traffic control.
Platinum's scarcity hinders widespread use of fuel cells, which provide power efficiently and without pollutants. Replacing some or all of this rare and expensive metal with common metals in a reactive, highly tunable nanoparticle form may expand fuel cell use.
Researchers have encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer to reality.
NASA has selected UT Arlington as one of four U.S. institutions to develop improved methods for oxygen recovery and reuse aboard human spacecraft, a technology the agency says is crucial to 'enable our human journey to Mars and beyond'.
