We recently demonstrated molecular plasmons in cyanine dyes for the conversion of photon energy into mechanical energy through a whole-molecule coherent vibronic-driven-action. Here we present a model, a molecular plasmon analogue of molecular orbital theory and of plasmon hybridization in metal nanostructures. This model describes that molecular plasmons can be obtained from the combination or hybridization of elementary molecular fragments, resulting in molecules with hybridized plasmon resonances in the electromagnetic spectrum.

Electrochemical devices that can operate at temperatures of 200-300 °C are expected to become the next-generation energy conversion devices in fuel cells and electrosynthesis, which are important for achieving carbon neutrality. Proton conductors based on phosphate glasses are being developed as candidate materials for such devices. We recently developed a glass proton conductor by using silicophosphoric acid based on the idea of solidifying phosphoric acid with silicon as a cross-linking glass framework.

Hypohalites are commonly generated in biological systems, mostly with functions related to defense and immune system response. These hypohalites can bind to metal centers and are known for their strong oxidizing properties that play crucial roles in various biological processes. Herein, we report the synthesis, characterization and reactivity of novel biomimetic Ru(III)-hypochlorite complexes and focus the work on the electronic effects associated with the incorporation of methyl groups in a pentadentate ligand framework in an asymmetric fashion.

Background: Polycyclic aromatic hydrocarbons (PAHs) are one of the most dangerous persistent organic pollutants in the environment. Due to the discharge of chemical plants and domestic water, the existence of PAHs in sea water and lake water is harmful to human health. A method for rapid detection and removal of PAHs in water needs to be developed.

Background: Hypertrophic cardiomyopathy (HCM) is a leading cause of sudden cardiac death. Current diagnosis emphasizes the detection of left ventricular hypertrophy (LVH) using a fixed threshold of ≥15-mm maximum wall thickness (MWT). This study proposes a method that considers individual demographics to adjust LVH thresholds as an alternative to a 1-size-fits-all approach.
