Novel metal-organic framework is potential next-gen semiconductor
Researchers demonstrated a novel double-helical metal organic framework architecture in a partially oxidized form that conducts electricity, potentially making it a next-generation semiconductor.
A key development in the drive for energy-efficient electronics
Scientists have made a breakthrough in the development of a new generation of electronics that will require less power and generate less heat. It involves exploiting the complex quantum properties of electrons - in this case, the spin state of electrons.
Unraveling the optical parameters: New method to optimize plasmon enhanced spectroscopy
Researchers report the first accessible method to gain unprecedented insights into the plasmonic activity of a single nanoparticle during a typical tip-enhanced Raman spectroscopy experiment.
New metasurface helps make the switch to terahertz frequencies
The new highly efficient metasurface switch needs no metal or backing material. This means detectors using the switch would be smaller, thinner, more efficient, and require less power.
Engineered nanowrappers carry and release tiny cargo
Scientists have discovered a new method for creating hollow metallic nanostructures with regularly spaced and sized pores. The pores are large and regular enough to carry molecule or nanoscale-size particles of drugs and other substances.
Wrapped, layered semiconductors catch the light
Researchers discovered a new way to integrate semiconductor layers to make heterostructures. They found that layers of different compounds of tin and sulfur spontaneously separated during synthesis. This unique structure translates into excellent light absorption and energy transfer properties.
Optical control allows physicists to simulate and understand interactions between atoms
Scientists used silica micro-particles mixed into liquid crystals to investigate how atoms behave and interact. They explored optical control of hexagonal silica micro-particles whose surfaces were altered with dye molecules and dispersed in a liquid crystal.
Stacked nanodevice quickly detects harmful bacteria in blood
Engineers have created a tiny device that can rapidly detect harmful bacteria in blood, allowing health care professionals to pinpoint the cause of potentially deadly infections and fight them with drugs.
Graphene flakes on medical devices kill bacteria and prevent infections
Graphite nanoplatelets integrated into plastic medical surfaces can prevent infections, killing 99.99 per cent of bacteria which try to attach - a cheap and viable potential solution to a problem which affects millions, costs huge amounts of time and money, and accelerates antibiotic resistance.
Graphene cleans water more effectively
Graphil is a project that aims to create a market prototype for a new and improved way to purify water, using graphene.
How do you power billions of sensors? By converting waste heat into electricity
Scientists have revealed how the thermoelectric effect, or converting temperature differences into electricity, can be optimally used to power small, flexible devices. Their study has shown why thermoelectric device performance to date has not yet reached its full potential.
Wearable strain sensor based on optical transmittance of a CNT-embedded elastomer
Rsearchers have developed a novel wearable strain sensor based on the modulation of optical transmittance of a carbon nanotube (CNT)-embedded elastomer. The sensor is capable of sensitive, stable, and continuous measurement of physical signals.
