Researchers at IMDEA Nanociencia have fabricated high quality microspheres from conjugated organic polymer blends with excellent lasing properties. The laser emission of the microspheres has the highest quality factor reported to date, Q>18,000.

Carboxylic acid dianions (fumarate, maleate, and succinate) play a role in coordination chemistry and, to some extent, also in the biochemistry of body cells. An HZB team at BESSY II has now analyzed their electronic structures using RIXS in combination with DFT simulations. The results provide information not only on electronic structures but also on the relative stability of these molecules, which can influence…

Texas A&M researchers discovered a groundbreaking 1,000% increase in the storage capacity of water-based battery electrodes. This research is a step toward lithium-free batteries, allowing for better control over the domestic supply chain.

Researchers at Texas A&M University have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.

Scientists from Skoltech, MIPT, Prokhorov General Physics Institute of RAS, and a number of other research centers have shown microbubbles made of a protein called albumin to be effective vehicles for the delivery of photodynamic agents—drugs used in an advanced anti-cancer therapy that avoids many of the side effects associated with chemo- and radiation therapy. The findings are reported in Colloids and Surfaces…

Pharmaceutical scientists at the National University of Singapore (NUS) have developed a novel chemical reaction that enables the precise functionalization of peptides and proteins. This approach could provide a useful tool for bioconjugation and drug discovery.

Helicenes are organic molecules that gained widespread popularity due to their unique helical π-conjugated molecular structure, where the benzene rings are ortho-fused, resulting in excellent chiroptical properties such as circularly polarized luminescence (CPL). The ability to act as a CPL emitter makes helicenes ideal for a wide range of next-generation optoelectronic applications, such as optical information…

Supramolecular polymers (SPs) are molecular assemblies composed of non-covalently bonded small molecules. They show high recyclability originating from their dynamic nature of monomer binding, which is different from covalent polymers with non-biodegradable nature.

The role of molecular junctions in nanoelectronics is most often associated with electronic transport; however, their precise characterization hinders their widespread development. Recently, most research has focused on investigating molecular junctions based on electronic characterization.

A new study by researchers at the University of Cambridge reveals a surprising discovery that could transform the future of electrochemical devices. The findings offer new opportunities for the development of advanced materials and improved performance in fields such as energy storage, brain-like computing, and bioelectronics.

In a study published in the journal National Science Review and led by Dr. Zhao-Yang Li (School of Material Science and Engineering, Nankai University) and Prof. Masahiro Yamashita (Department of Chemistry, Graduate School of Science, Tohoku University), a photoisomerizable ligand was used to synthesize two VT coordination polymers, which display VT and photoconversion behavior.

The demand for real-time health monitoring is growing. A research team from the Institute of Chemistry of the Chinese Academy of Sciences (ICCAS) recently developed a living material for real-time monitoring of lactate, a biomarker for cancer.

Carbon dots (CDs) are new carbon-based photoluminescence (PL) nanomaterials with a core-shell motif. Due to their fascinating advantages, such as chemical inertness, high quantum yields (QYs), high water solubility, thermal stability, and excellent biocompatibility, CDs have attracted extensive attention in various research applications, such as cancer diagnosis, phototherapy, and optoelectronic devices. However,…

Diamond and graphite are two naturally occurring carbon allotropes that we have known about for thousands of years. They are elemental carbons that are arranged in a manner so that they consist of sp3 and sp2 hybridized carbon atoms, respectively. More recently, the discovery of various other carbon allotrope materials, such as graphene, fullerene, carbon nanotube, graphyne, and graphdiyne, has been revolutionizing…

In work published online recently in National Science Review, a team led by Prof. Hua Lu from the College of Chemistry and Molecular Engineering of Peking University reported a surprising finding. In the process of studying the ROP of ProNCA, a type of reaction that would otherwise have been performed in a dry box, the team discovered ultrafast and controlled polymerization in aqueous solutions.

Conventional silicon-based transistors, which sit at the heart of every computer, are fast approaching the limit of miniaturisation. Here, Meng et al demonstrate a field-effect transistor composed of a single rutheniumdiarylethene molecule with large on/off ratio.

Currently, the world's energy demand mainly depends on fossil fuels being a limited resource. The consumption of fossil fuels leads to emission of carbon dioxide (CO2) that is one of the major greenhouse gases contributing to global warming and climate changes. We need to urgently establish sustainable energy societies based on renewable energy sources. On the other hand, nature has perfected an ultimate solar…

The challenge of regulating the electronic structures of metal single-atoms (M-SAs) with metal nanoparticles (M-NPs) lies in the synthesis of a definite architecture. Such a structure has strong electronic metal-support interactions and maintains electron transport channels to facilitate carbon dioxide photoreduction (CO2PR).

Researchers have demonstrated a new material for single-molecule electronic switches, which can effectively vary current at the nanoscale in response to external stimuli. The material for this molecular switch has a unique structure created by locking a linear molecular backbone into a ladder-type structure. A new study finds that the ladder-type molecular structure greatly enhances the stability of the material,…
