Scientists have found a way to package antimicrobial compounds from peppermint and cinnamon in tiny capsules that can both kill biofilms and actively promote healing. The researchers say the new material could be used as a topical antibacterial treatment and disinfectant.
The development of metal oxide-based molecular wires is important for fundamental research and potential practical applications. However, examples of these materials are rare. Researchers now successfully created ultrathin all-inorganic molecular nanowires, composed of a repeating hexagonal molecular unit made of Mo and Te; the diameters of these wires were only 1.2 nm.
In a new study, electrical engineers have designed a cloaking device that is both thin and does not alter the brightness of light around a hidden object. The technology behind this cloak will have more applications than invisibility, such as concentrating solar energy and increasing signal speed in optical communications.
A new approach to develop highly-potent drugs which could overcome current shortcomings of low drug efficacy and multi-drug resistance in the treatment of cancer as well as viral and bacterial infections.
Physicists have used graphene to build lightweight ultrasonic loudspeakers and microphones, enabling people to mimic bats' or dolphins' ability to use sound to communicate and gauge the distance and speed of objects around them.
Using a single molecule as a sensor, scientists have successfully imaged electric potential fields with unrivalled precision. The ultrahigh-resolution images provide information on the distribution of charges in the electron shells of single molecules and even atoms.
