π-Extended Azacoronene with a Janus Double-Concave Structure
27 Apr 2021
A facile synthesis of two types of pyrrole-fused azacoronene with planar and double-concave π-structures was achieved. The two electron-rich azacoronenes were found to interact with electron-deficient π-electron compounds depending on their three-dimensional structures. Azacoronene with a curved structure was found to be less aromatic than those with a planar one based on macrocyclic π-conjugation.

They observed that the theta and sharp-wave/ripples in the subiculum controlled information transmission with millisecond precision according to the target region. This provides the foundation for a comprehensive understanding of the hippocampal memory system.

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.
High-throughput sample preparation for mass spectrometry-based protein analysis using BAC-DROP
18 Feb 2021
Polyacrylamide gel electrophoresis enables high-resolution separation of proteins extracted from biological samples, but it requires more than one day of pretreatment to recover the separated proteins trapped inside the gel for detection by mass spectrometry. BAC-DROP, our novel electrophoresis technology, uses a dissolvable form of polyacrylamide gel, which allows sample pretreatment to be completed in about 5 hours. The developed technology will enable the rapid diagnosis of viruses and disease protein markers.

Carbon dioxide (CO2) is one of the major greenhouse gases causing global warming. If the carbon dioxide could be converted into energy, it would be killing two birds with one stone in addressing the environmental issues. A joint research team led by City University of Hong Kong (CityU) has developed a new photocatalyst which can produce methane fuel (CH4) selectively and effectively from carbon dioxide using sunlight. According to their research, the quantity of methane produced was almost doubled in the first 8 hours of the reaction process.
