Making thin films out of semiconducting materials is analogous to how ice grows on a windowpane: When the conditions are just right, the semiconductor grows in flat crystals that slowly fuse together, eventually forming a continuous film.
Researchers have been exploring natural, safe and alternative antimicrobials to reduce bacterial contamination. Plant essential oils such as those from thyme, oregano and clove are known to have a strong antimicrobial effect, but currently their use in food protection is limited due to their low solubility in water. The team explored ways to formulate oil nanoemulsions to increase the solubility and stability of essential oils, and consequently, enhance their antimicrobial activity.
Most people are naturally adept at reading facial expressions - from smiling and frowning to brow-furrowing and eye-rolling - to tell what others are feeling. Now scientists have developed ultra-sensitive, wearable sensors that can do the same thing.
IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors simultaneously, as well as demonstrated a new, square quantum bit circuit design that is the only physical architecture that could successfully scale to larger dimensions.
Researchers have found a method that allows them to ensure that living cells - in this case bacteria from the human body - can be incorporated in materials while maintaining their mobility. This opens the way to a wide range of new applications, for example as part of medical implants.
Researchers have proposed a new thermo-elasto-plasticity constitutive model based on the interatomic potential and solid mechanics for metal crystals. Through this new model, the material behavior at different temperatures could be described accurately and conveniently.
