Addition of lithiated dithianes to diaryl ketones, potential electron-transfer sensitizers, disrupts conjugation between the two aromatic moieties, effectively masking the sensitizer. A novel photoamplification strategy is developed based on photosensitized cleavage in such adducts, where each fragmentation event releases more diaryl ketone, capable of sensitization. As a result, mass release o...

Dye sensitized solar cells (DSSCs) use low-cost materials, feature tunable molecular sensitizers, and exhibit quantum efficiencies near unity. These advantageous features can be exploited in the context of solar water splitting by functionalizing DSSCs with catalysts for water oxidation and reduction. This article will cover the development of photoanodes for water splitting DSSCs from the pers...

Calciphylaxis may be considered a small vessel vasculopathy which is generaly associated with end-stage renal disease and hyperparathyroidism. The precise pathogenesis of the disease is not known. It needs sensitizers and challengers to occur. Steroids and immunosuppressive drugs including methotrexate are among those challenger agents. Calciphylaxis in collagen vascular diseases is rare. Only ...

A diarylethene photoswitch was covalently connected to two small triplet sensitizer moieties in a conjugated and nonconjugated fashion and the photochromic performance of the resulting compounds was investigated. In comparison with the parent diarylethene (without sensitizers) and one featuring saturated linkages, the conjugated photoswitch offers superior fatigue resistance upon visible-light ...

Abstract Visible light-driven production of fuels and value-added chemicals is currently one the most intensely investigated research topics across various scientific disciplines, due to its potential ease World’s dependence on fossil fuels. In this perspective, we recapitulate some main features dye-sensitized photocatalytic systems aimed at solar H 2 production, focusing in particular TiO -ba...

Exceptional overlap of dye absorption with indoor light spectra, achieving 30.24% efficiency devoid co-sensitizers and realizing the self-powered operation IoT devices.

In the treatment of heart failure, clinical signs are low cardiac output, therapy with positive inotropic agents in an acute cardiac care is mandatory. Three classes of inotropic drugs are currently used, including betaadrenergic agonists (especially dobutamine), phosphodiesterase inhibitors (such as milrinone) and the recently developed calcium sensitizers such as levosimendan. The classic ino...

Drug treatment of 2 diabetes is intended to normalize glycosylated hemoglobin levels (HbA(1c)<6.5%) and thereby prevent the development of micro- and macrovascular complications. Oral antidiabetic agents target the metabolic abnormalities that cause diabetes. The two principal families of oral antidiabetic agents - insulin sensitizers and insulin secretagogues - can be taken together. Thiazolid...
