Combined microscopy technique catches light-driven polymers in the act

ScienceDaily.com: Nanotechnology News - 11 марта, 2024 - 21:55
Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.

Harnessing nature's shield: Enhancing sun protection with lignin nanoparticles in cosmetics

Physorg.com - 11 марта, 2024 - 20:41
Lignin nanoparticles (LNPs) have emerged as promising candidates for enhancing sun protection in cosmetics, offering superior UV-blocking capabilities compared to soluble lignin oligomers. However, the effects of the chemical structures of constituting lignin oligomers in LNPs and the particle size distribution of LNPs need further investigation. Additionally, the raw materials used in these works were mainly technical lignin, whose structures significantly changed during the extraction process, making them unsuitable for studying the structural effect of UV-blocking.

Flexible AI optoelectronic sensors pave the way for standalone energy-efficient health monitoring devices

Physorg.com - 11 марта, 2024 - 18:18
From creating images, generating text, and enabling self-driving cars, the potential uses of artificial intelligence (AI) are vast and transformative. However, all this capability comes at a very high energy cost. For instance, estimates indicate that training OPEN AI's popular GPT-3 model consumed over 1,287 MWh, enough to supply an average U.S. household for 120 years.

Researchers use 2D bimetallic MOFs to create Se-containing electrocatalysts for overall water splitting

Physorg.com - 8 марта, 2024 - 19:59
Transition metal selenides have been considered to be a good choice for electrocatalytic water splitting. In addition, Metal-organic frameworks (MOFs) have been used to make catalysts with good electrocatalytic capabilities. Traditionally, the MOF-derived selenides are produced via the self-sacrificing MOF template methods. However, this strategy is high-energy consuming, and it is difficult to precisely control the structure and component homogeneity of the product during pyrolysis.
