ContextBrown adipose tissue is of metabolic interest. The tissue is however poorly explored in children.

Additive manufacturing (AM) is an emerging processing platform in clinical applications because of its ability to fabricate customized 3D structures for patient-specific needs. Vat photopolymerization additive manufacturing creates high-resolution, complex structures with excellent accuracy to f...

Lithium–sulfur batteries have attracted considerable interest because of their high energy density, non-toxicity, and low-cost. However, the main challenges associated with the dissolution of lithium polysulfides and low conductivity of sulfur are still required to be overcome to achieve improv...

Microalgae accumulate neutral lipids in oil bodies under sulfur-starvation conditions, and determination of the molecular basis of lipid accumulation under sulfur-starvation conditions will enable improvement of the production of biofuel. We analyzed two l-cysteine dependent mutants (Srp1 and Sr...

Thermochemical water splitting cycles (TWSCs) are processes with the potential for large-scale production of carbon-free hydrogen. Among these, the sulfur-family thermochemical cycles are considered the most promising due to both, the use of readily affordable chemical reagents and the temperatu...

A versatile, rapid and safe green method for chlorine and sulfur determination using ion chromatography in cereals and legumes was developed. Microwave-induced combustion was evaluated for sample preparation. Ultrapure water and alkaline solutions were assessed for absorption of the analytes. Wa...

A series of spectroscopic measurements were performed on membrane fractions and detergent-solubilized complexes from the green sulfur bacterium (GSB) Chlorobaculum (Cba.) tepidum. The excitation migration through the entire GSB photosynthetic apparatus cannot be observed upon excitation of membr...

Carbon dots co-doped with nitrogen and sulfur (N/S-CDs) were prepared with the model bloom-forming green alga Dunaliella salina via a one-step hydrothermal reaction, i.e., no chemicals were required. The obtained N/S-CDs with average particle size about 3.2 ± 0.5 nm exhibited great photostabili...

Natural H2S-CH4 inclusions enclosed in quartz were transformed into H2-CH4 mixture with none or negligible H2S concentration after short irradiation of associated sulphur daughter phase with 532 nm photons emitted by a 25 mW Nd-YAG laser. As much as 57 mol. % (73.8 wt %) H2S in the gas inclusion...

Citrus industry residues are sources of phenolic compounds, which may be extracted by pressurized liquid extraction (PLE) and volatile compounds, extractable by supercritical fluid extraction (SFE). PLE and SFE are fast and allow using non-toxic solvents and moderate temperatures. Therefore, the...

The present work describes the preparation of titanium oxide impregnated polyacrylamide hydrogel (TiO2/PAM) by in-situ polymerization technique. The prepared hydrogel was characterized by fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and x-ray diffraction (X...

The systematic analysis of different organic solvents influence on the morphology of TiO2 nanotubes (TNTs) via hydrothermal synthetic route with the addition of alkaline solution and commercial TiO2 nanoparticles is performed through characterizations. The photocatalytic activity of TNTs was inv...

A challenge in Photonics and Optoelectronics is to take advantage of specific environmental forces to enhance the nonlinear optical response of π-organic materials. Under this statement, it is carried out a systematic QM/MC investigation of the solvent effects on the linear and nonlinear optica...

The electrochemical behaviour of methylene blue in solution of non-aqueous solvents with different supporting electrolytes was studied by cyclic voltammetry. Dye electro-reduction presents two well-defined processes of monoelectronic charge transfer yielding a free radical in the first process a...

The spectral and luminescent properties of meso-propargylamino-boron (III) dipyrromethenate (BODIPY 1) were studied in a wide range of organic solvents of different polarities, electron- and proton-donating abilities. Effect of organic solvents on the properties of the BODIPY 1 spectral characte...

SummaryIn chick embryos, unlike in adults, many neurons can be impregnated selectively with the Loyez iron-haematoxylin method, and with the MBSN and ARN types of Luxol Fast Blue. The same neurons are selected with each of the 3 methods. Their distribution at a given age is roughly predictable, ...

Yellow fever, a mosquito-borne flavivirus disease occurs in tropical areas of South America and Africa. It is a disease of major historical importance, but remains a threat to travelers to and residents of endemic areas despite the availability of an effective vaccine for nearly 70 years. An imp...

Biogenic Silica (BSi) plays an essential role in availability of dissolved silicate (DSi) in aquatic ecosystems, but its role in silica cycling is still poorly characterized in the river and estuary systems. This study addressed the riverine BSi composition and reactive silica (RSi) export in th...

In this study, a new sorbent was prepared by the chemical modification of silica gel with 2,2′-(hexane-1,6-diylbis(oxy))dibenzaldehyde (SiO2-NH2-BH) through a Schiff base bond formation by a normal method and a vice versa method. The structure and morphology of the synthesized materials were ch...
