Researchers in Japan have found an energy-efficient way to convert the chief greenhouse gas carbon dioxide (CO2) into useful chemicals. Using the method, CO2 is transformed into structures called metal-organic frameworks (MOFs), suggesting a new and simpler route to dispose of the greenhouse gas to help tackle global warming.

Researchers at Kanazawa University describe in Scientific Reports the identification of small compounds that can regulate the cellular production of extracellular vesicles — nanocontainers transporting biomolecules between cells. Such compounds hold promise for use in therapies for various diseases.

Perovskite colloidal quantum dots (Pe-CQDs) are highly promising nanocrystals for optoelectronic applications. However, the size of the crystals should ideally be equal to ensure a consistent energy landscape. In a recent study, scientists clarified the relationship between differences in particle size—polydispersity—and the optoelectronic characteristics of Pe-CQDs. They showed that using equally sized, or ‘monodisperse,’ quantum dots results in markedly better performance in Pe-CQD solar cells, paving the way for future optoelectronic devices.

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 at Kanazawa University report in Communications Chemistry that a molecule known as pillar[6]arene can form a host–guest compound with a cancer-associated metabolite. The phenomenon can be used to efficiently detect the metabolite in crude biological samples, which is important for preventing and treating metabolic syndrome and associated pathologies.

For the first time, researchers have used a novel catalyst process to recycle a type of plastic found in everything from grocery bags and food packaging to toys and electronics into liquid fuels and wax.
BioAFMviewer

Atomic force microscopy (AFM) allows to obtain images and movies showing proteins at work, however with limited resolution. The developed BioAFMviewer software opens the opportunity to use the enormous amount of available high-resolution protein data to better understand experiments. Within an interactive interface with rich functionality, the BioAFMviewer computationally emulates tip-scanning of any biomolecular structure to generate simulated AFM graphics and movies. They greatly help in the interpretation of e.g., high-speed AFM observations.

Hong Kong Baptist University (HKBU) scientists have invented a novel contrast agent for magnetic resonance imaging (MRI), which enables real-time visualisation and detection of the size and number of amyloid-beta in the brain, a main hallmark of Alzheimer’s disease (AD). The invention offers hope for early detection and large-scale routine screening of AD. It can also help to assess the efficacy of drugs used to treat it.

A hemispherical vanadium oxide cluster has a cavity that can accommodate a bromine molecule. It was found that a bromine molecule trapped in the cavity was polarized and that an alkane molecule like pentane, butane and propane could be brominated with the bromine molecule in the cavity with a selectivity differing from ordinary bromination. The present findings are expected to be useful for polarization of small molecules and design of highly functional catalysts.

Researchers at Kanazawa University report in Biomaterials a high-speed atomic-force microscopy study of protein filaments in the nuclear pore complex. The visualization in real-time of the filaments’ dynamics is an important step in our understanding of molecular transport mechanisms between a cell nucleus and its surrounding medium.

Researchers at Kanazawa University report in Analytical Chemistry an efficient method for filling a batch of nanopipettes with a pore opening below 10 nanometer. The method is based on the application of a temperature gradient to the nanopipette tips so that residual air bubbles are driven out.
