Artificial photosynthesis, the biomimetic approach to converting sunlight's energy directly into chemical fuels, aims to imitate nature by using an integrated system of nanostructures, each of which plays a specific role in the sunlight-to-fuel conversion process. Here we describe a fully integrated system of nanoscale photoelectrodes assembled from inorganic nanowires for direct solar water sp...

The transcriptional response of Staphylococcus aureus strain Newman to sunlight exposure was investigated under both oxic and anoxic conditions using RNA sequencing to gain insight into potential mechanisms of inactivation. S. aureus is a pathogenic bacterium detected at recreational beaches which can cause gastrointestinal illness and skin infections, and is of increasing public health concern...

Oxidation and reduction kinetics of iron (Fe) and proportion of steady-state Fe(II) concentration relative to total dissolved Fe (steady-state Fe(II) fraction) were investigated in the presence of various types of standard humic substances (HS) with particular emphasis on the photochemical and thermal reduction of Fe(III) and oxidation of Fe(II) by dissolved oxygen (O2) and hydrogen peroxide (H...

In this work, the dissipation of antibiotics doxycycline (DC) (from group tetracyclines), enrofloxacin (ENR) (a fluoroquinolone), and sulfamethoxypyridazine (SMP) sulfonamide) is investigated both under simulated sunlight in dark, at three different pH (4.0, 5.5, 7.2), presence salts humic acids. The results indicate that all are very sensitive to photodegradation, sensitivity increased with ri...

The indoor climate of industrial buildings is a function production technology and requirements for the creation an optimal artificial material environment. Currently, we consider daylight not only as source illumination, but also aesthetic element building or way reducing energy consumption. Light in closed space allows person to obtain basic visual information (perception) perform tasks. Top ...

The ultraviolet radiation present in sunlight is the primary cause of nonmelanoma skin cancer and has been implicated in the development of cutaneous malignant melanoma. In addition, ultraviolet is immune suppressive and the suppression induced by ultraviolet radiation has been identified as a risk factor for skin cancer induction. Ultraviolet also suppresses the immune response to infectious a...
