The mechanisms of suppression and enhancement of photocurrent/conversion efficiency (performance) in dye-sensitized solar cells, using carotenoid and chlorophyll derivatives as sensitizers, were compared systematically. The key factor to enhance the performance was found to be how to minimize interaction among the excited-state dye-sensitizer(s). In a set of retinoic-acid (RA) and carotenoic-ac...

Up to 60 million people working indoors experience symptoms such as eye, nose and throat irritation, headache, and fatigue. Investigations into these complaints have ascribed the effects to volatile organic compounds (VOCs) emitted from building materials, cleaning formulations, or other consumer products. New compounds can result when the VOCs react with hydroxyl or nitrate radicals or ozone p...

For increasing myocardial contractility in patients with cardiac failure, catecholamines, phosphodiesterase-III (PDE) inhibitors, and calcium sensitizers are available. Improving myocardial performance with catecholamines and PDE inhibitors leads to increased intracellular calcium concentration as an unavoidable side effect. An increase in intracellular calcium can induce harmful arrhythmias an...

Preclinical, early phase clinical trials and epidemiological evidence support the potential role of insulin-sensitizers in cancer prevention and treatment. Insulin-sensitizers improve the metabolic and hormonal profile in PCOS patients and may also act as anticancer agents, especially in cancers associated with hyperinsulinemia and oestrogen dependent cancers. Several lines of evidence support ...

Recently, the combined application of synergistic therapies for photodynamic antimicrobial chemotherapy has become important to obtain more efficient results. The synergism between two sensitizers, rose bengal (RB) and chlorin e6 (Ce6), excited by different methods, was evaluated as a novel approach both sonodynamic therapy against methicillin-resistant Staphylococcus aureus. sonostability sing...

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...

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...
