Jan 16, 2024 (Nanowerk News) Not every wound can be closed with needle and thread. Empa researchers have now developed a soldering process with nanoparticles that gently fuses tissue. The soldering technique is expected to prevent wound healing disorders and life-threatening complications from leaking sutures. The team recently published the...
Plasmonic metasurface anti-icing film only requires sunlight
Jan 16, 2024 (Nanowerk News) A KAIST research team has developed an anti-icing and de-icing film coating technology that can apply the photothermal effect of gold nanoparticles to industrial sites without the need for heating wires, periodic spray or oil coating of anti-freeze substances, and substrate design alterations. The group...
Tailored nanograins enable greener ammonia production
Jan 15, 2024 (Nanowerk Spotlight) Ammonia is indispensable for producing the fertilizers and chemicals that sustain food and material production for billions globally. However, conventional industrial scale ammonia synthesis comes at great environmental costs. The predominant century-old Haber-Bosch method accounts for over 2% of energy use worldwide, while generating substantial...

Microbiologists and biophysicists from the University of Bonn have now developed a method that makes the high-throughput process for...
Research sheds new light on Moon rock formation solving major puzzle in lunar geology
Jan 15, 2024 (Nanowerk News) New research has cracked a vital process in the creation of a unique rock type from the Moon. The discovery explains its signature composition and very presence on the lunar surface at all, unravelling a mystery which has long eluded scientists. The study, published in...
Breakthrough method enables scalable hexagonal boron nitride synthesis for superior corrosion protection
Jan 15, 2024 (Nanowerk News) Industrial metals face an unrelenting threat from corrosion and degradation that drains trillions annually. Yet effective large-scale protection has remained elusive, frustrating both structural engineers and asset managers alike. Advanced coatings once seemed poised to deliver a breakthrough after graphene isolation enabled investigation of other...
Physicists identify overlooked uncertainty in real-world experiments like optical tweezers
Jan 15, 2024 (Nanowerk News) The equations that describe physical systems often assume that measurable features of the system — temperature or chemical potential, for example — can be known exactly. But the real world is messier than that, and uncertainty is unavoidable. Temperatures fluctuate, instruments malfunction, the environment interferes,...
‘Optical fingerprints’ on an electron beam
Jan 15, 2024 (Nanowerk News) The precise control of electron beams in so-called transmission electron microscopes (TEM) makes it possible to analyze materials or molecules at the atomic level. Combined with short light pulses, these devices can also be used to analyze dynamic processes. Researchers from Göttingen and Switzerland have...
Bladder tumors reduced by 90% using nanorobots
Jan 15, 2024 (Nanowerk News) Bladder cancer has one of the highest incidence rates in the world and ranks as the fourth most common tumour in men. Despite its relatively low mortality rate, nearly half of bladder tumours resurface within 5 years, requiring ongoing patient monitoring. Frequent hospital visits and...
