Nowadays, the best lead sulfide (PbS) colloidal quantum dot (CQD) solar cells are primarily demonstrated in n-p structure, while p-n structure is significantly less developed. This technological gap between and structures much more distinct than cases of other solution-processable photovoltaic technologies like perovskites polymers. Here, we propose a scalable fabrication strategy for efficient...

One of the emerging paradigms to resolve pressing issues modern computing electronics, such as limits in miniaturization and excessive energy consumption, takes inspiration from biological brain is therefore expected display some its properties, efficiency effective learning. Moreover, one brain's remarkable properties ability process complex information by resolving it on different timescales....

During the fission of Uranium for generating electricity, products are produced. Ru-106 is one among them. In decontamination nuclear components using decontaminating agents like EDTA, NDA, oxalic acid etc, Ruthenium gets complexed and waste generated as liquid contains in complex state. It necessary to free from by oxidation complex. This will generate effluent with state amenable further trea...

Toxic effects of sulfide come from a poisoning of a number of enzymes, especially cytochrome c oxidase, which catalyzes the terminal step in mitochondrial aerobic respiration. Despite this, some estuarine plants live in sulfide-rich sediments. We hypothesized estuarine and flooding-tolerant species might be more tolerant of sulfide compared to upland species, and this was tested by measures of ...

Interactions between iron and sulfide in domestic wastewater from a gravity sewer were investigated with particular emphasis on redox cycling of iron and iron sulfide formation. The concentration ranges of iron and total sulfide in the experiments were 0.4-5.4mgFeL(-1) and 0-5.1mgSL(-1), respectively. During anaerobic conditions, iron reduction kinetics were investigated and reduction rates amo...

ABSTRACT. The effects of copper concentration on the properties lead sulfide thin films have been reported. Chemical bath deposition (CBD) method was used to deposit ternary material soda-lime substrates. Here, were grown using copper(II) chloride, nitrate, and thiourea as sources (Cu), (Pb) sulfur (S), respectively. examined X-ray diffractometer (XRD), scanning electron microscopy (SEM), energ...

Some organisms that survive in environments rich in hydrogen sulfide possess specific metabolic pathways for sulfide oxidation and subsequent use of reducing equivalents in oxidative phosphorylation, a process called chemolithoheterotrophy. This process is dependent on ambient oxygen partial pressure and environmental sulfide exposure. To define accurately the kinetics of sulfide metabolism and...
