In a multi-institutional collaboration, one SUTD researcher finds a way to optimise the design of perovskite tandem solar cells using machine learning.

Researchers from Osaka University found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.

A research group led by Associate Professor Katsuya Sakai, Researcher Nichole Marcela Rojas-Chaverra, and Professor Kunio Matsumoto of the Cancer Research Institute and Nano-Life Science (WPI-NanoLSI) at Kanazawa University has developed a long-acting, subcutaneously injectable artificial hepatocyte growth factor (HGF) mimetic molecule using a fusion technology of cyclic peptides and protein engineering. They demonstrated in a mouse model that it improves liver fibrosis, lipid accumulation, and inflammation caused by non-alcoholic steatohepatitis (NASH). This research result provides an option for the development of NASH therapeutics as well as a technology for creating growth factor and cytokine mimetic molecules with improved pharmacokinetics.

A new treatment combining tiny iron particles and nitric oxide gas shows promise in targeting oral cancer cells for destruction.

Researchers from the HeKKSaGOn Alliance – involved were scientists from Kyoto University, Osaka University and Heidelberg University (Germany) – synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.

Sometimes less is more. Researchers at Tohoku University accurately modeled dynamic fish schooling by incorporating the tendency of fish to focus on a single visual target instead of the whole school.

This study presents a method to record the temperature of materials with exceptional temporal resolution, using a Doppler broadening effect in neutron resonance absorption. Using a high-powered laser to generate pulses of neutrons 100 nanoseconds long, a test on samples of silver and tantalum successfully returned characteristic information for both materials and their temperatures.
