Researchers at Osaka Prefecture University have established an approach to identify the orientation of molecules and chemical bonds in crystalline organic-inorganic hybrid thin films deposited on substrates using Fourier transform infrared spectroscopy (FT-IR) and polarized infrared light with a 3D-printed attenuated total reflectance (ATR) unit. This inexpensive method with laboratory-grade equipment quickly reaches the crystal-structure model of even extremely thin films of less than 10 nm.

Researchers discovered, while exploring the photomechanical properties of diarylethene, that under irradiation with UV light the crystal of the compound peels off into micrometer sized crystals at a world’s fastest speed of 260 microseconds. As the material returns to its former molecular structure when exposed to visible light, the exfoliation method positions itself as a candidate for photoactuator manufacturing.

The promotion of electric cars has dramatically increased the demand for lithium-ion batteries. However, cobalt and nickel, the main cathode materials for the batteries, are not abundant. If the consumption continues, it will inevitably elevate the costs in the long run, so scientists have been actively developing alternative materials. A joint research team co-led by a scientist from City University of Hong Kong (CityU) has developed a much more stable, manganese-based cathode material. The new material has higher capacity and is more durable than the existing cobalt and nickel cathode materials - 90% of capacity is retained even when the number of charging-recharging cycles doubled. Their findings shed lights on developing low cost and high efficiency manganese-based cathode materials for lithium-ion batteries.

The fine structure of barium titanite, a potential alternative to lead titanite, has been revealed by researchers employing a novel technique over the extremely short time period that the ferroelectric phenomena experienced by these materials occur. The investigation should assist further exploration of how to replace lead titanate with other materials, so that its widespread applicability may be enjoyed while avoiding its role in lead pollution.
a novel electrode material for ASSBs
18 Feb 2021
Lithium ion batteries use liquid electrolytes that have several drawbacks, which can be overcome by all-solid-state lithium secondary batteries (ASSBs). However, it is important to find efficient electrode materials for ASSBs. A research team from Japan has recently developed a novel electrode material for ASSBs by combining lithium sulfate and lithium ruthenate, which results in improved performance. The scientists hope that their novel approach will guide future research and the eventual commercialization of such high-capacity batteries.
