Propylene production harnesses biodiesel waste byproduct

Researchers from Osaka University fabricated copolymers with chiral backbones based on indacenodithiophene. Spin-coated films of the copolymers behaved differently toward currents with opposite polarization, resulting in chirality-induced spin selectivity. The magnitude of this selectivity was quantified as a spin polarization of almost 70%, which is among the highest achieved to date for a chiral polymer. These chiral copolymer films are attractive for use as spin filters in spintronics applications.

Researchers from Osaka University have designed and synthesized a new organic semiconductor for organic solar cells (OSCs). By adding specific side units to their structure, they achieved separation between the frontier molecular orbitals, leading to lower exciton binding energy and increased power conversion efficiency. This tuning of the design of an acceptor component is expected to increase the performance of OSCs leading to more effective large-scale photovoltaic systems and new devices.

Foaming plastic carriers creates uneven surfaces, more area for necessary microorganisms

This study reports the first attempt to characterize the quality, defects, and strain of as-grown monolayer transition metal dichalcogenide (IMDC)-based 2D materials through exciton anisotropy. A standard ellipsometric parameter (Ψ) to observe anisotropic exciton behavior in monolayer 2D materials is used. According to the strong exciton effect from phonon-electron coupling processes, the change in the exciton in the Van Hove singularity is sensitive to lattice distortions such as defects and strain. In comparison with Raman spectroscopy, the variations in exciton anisotropy in Ψ are more sensitive for detecting slight changes in the quality and strain of monolayer MDC films. Moreover, the optical power requirement for TMDC characterization through exciton anisotropy in Ψ is ~10-5 mW·cm-2, which is significantly less than that of Raman spectroscopy (~106 mW·cm-2). The standard deviation of the signals varies with strain (defects) in Raman spectra and exciton anisotropies in Ψ are 0.700 (0.795) and 0.033 (0.073), indicating that exciton anisotropy is more sensitive to slight changes in the quality of monolayer TMDC films.

Lithium-ion batteries are widely used daily in electronic appliances, and with the growing popularity of electric vehicles globally, battery safety has become a mounting concern. The development of battery monitoring and fault diagnosis technologies is therefore crucial. Prof Tang Xiaopeng, Assistant Professor of the Science Unit at Lingnan University, in collaboration with researchers from the University of Shanghai for Science and Technology, Shanghai University of Engineering Science, and Tongji University, has proposed a small-sample-learning-based, deep learning model to accurately predict the battery electrochemical impedance spectroscopy (EIS), making it a low-cost, very efficient and highly accurate battery assessment method. The co-authored paper "Online multi-scenario impedance spectra generation for batteries based on small-sample learning" was recently published in the prestigious international academic journal "Cell Reports Physical Science".

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.

The system was selective for heavy metals and provides a new way to remove specific contaminants from water.
