Researchers have recently demonstrated that high-intensity focused ultrasound (HIFU) is a promising, non-invasive stimulus with multiple superior and unique capabilities to induce localized heating and achieve temporal and spatial thermal effects in polymers. The team proposes a new manner of stimulating stimuli-responsive polymers. These polymers demonstrate promise for controlled drug delivery, sensing and biosensing, smart coatings, soft robotics, and flexible electronics among others.

Researchers have created new graphene and silicon Schottky contact-based infrared radiation sensors that are more effective than the infrared sensors currently used in the market.
Material scientists have presented antibacterial nano-coatings based on boron nitride, which are highly effective against microbial pathogens (up to 99.99%). They can become a safe alternative to the usual antibiotics in implantology since they do not have typical negative side effects.
Further development of this technique will lead to novel methods to predict stages of manifestation of diseases like cancer, atherosclerosis, and fibrosis from simple tissue fluids or blood samples.
For the first time, researchers have successfully described the impact water molecules have on other water molecules and on ions as part of the filtration mechanism. The researchers detail a feedback system between water molecules which opens up new design possibilities for highly selective membranes.
Physicists have developed an integrated circuit using magnetic material and magnons to transmit binary data, the 1s and 0s that form the foundation of today's computers and smartphones.
Researchers are picking up the challenge of 'scavenging' invisible power from low-frequency vibrations in the surrounding environment, including wind, air or even contact-separation energy (static electricity).
This new setup, using AFMs and carbon nanotubes, is relatively low-cost compared to other existing nanopatterning equipment or techniques, such as laser-based or electron beam-based setups.
Researchers have synthesized a unique molecule with a surprising property: it can absorb near infrared light. The molecule is made only of hydrogen and carbon atoms and offers insights for making organic conductors and batteries.
