We report on the 3D precipitation, using a direct laser writing approach, of highly fluorescent silver clusters in Eu3+-doped silver-containing zinc phosphate glass. Micro-spectroscopy fluorescence emission shows ability to continuously adjust local tri-chromatic coordinates CIE (Commission Internationale de l’Éclairage) chromaticity diagram between red and white colors, thanks laser-deposited ...

Abstract This paper reports new hierarchical cementitious composites developed using microcrystalline cellulose (MCC), sisal fibers and cetyltrimethylammonium bromide (CTAB) as the dispersing agent. MCC was dispersed in water without with CTAB at different concentrations ultrasonication optimum concentration for achieving homogeneous stable suspensions found to be 40%. Hierarchical were fabrica...

hemoglobin is a porphyrin containing protein with an a2b2 tetrameric structure and like other porphyrin compounds shows spectral behavior of species specific characteristics. researchers tend to relate bands in the hemoglobin spectra to certain structural and/or functional features. given the fact that hemoglobin is the main oxygen carrier in animals functioning through the oxy«deoxy equilibriu...

In the Tabas coal preparation plant (SE Iran), -50 + 6 mm raw coal was treated in a 700 mm two-stage two-density Tri-Flo dynamic dense medium separator. In order to study the circuit performance and to evaluate the separator efficiency, 32 mm cubic density tracers were used in the range of 1.28-2.1 g/cm3 and under different operational conditions. The performance of Tri-Flo was evaluated in a r...

BACKGROUND The radial approach has been increasingly used as an alternative to femoral access. And more procedures using repeated transradial coronary intervention (r-TRI) are performed. However, few data about r-TRI has been obtained. Therefore, we investigated the safety and feasibility of r-TRI using the same route. METHODS A total of 423 consecutive eligible patients undergoing r-TRI were...

Tri-o-cresyl phosphate (TOCP) is a widely used organophosphorus compound, which can cause a neurodegenerative disorder, i.e., organophosphate-induced delayed neurotoxicity (OPIDN). The biochemical events in the initiation of OPIDN were not fully understood except for the essential inhibition of neuropathy target esterase (NTE). NTE, located in endoplasmic reticulum (ER), catalyzes the deacylati...

The extractive separation of tellurium (IV) from hydrochloric acid media with tri-n-butyl phosphate (TBP) in kerosene was investigated. The dependence on the extraction of tellurium species, concentrations of tellurium and TBP, extraction time and stage, organic/aqueous ratio, and interferences from coexist metallic ions were examined and are discussed. Besides, the stripping agent and strippin...

1. Conversion of thyroxine into tri-iodothyronine and reverse tri-iodothyronine in intact cells was studied with isolated renal tubules prepared by collagenase digestion. 2. Conversion of thyroxine into tri-iodothyronine and reverse tri-iodothyronine increased progressively for at least 90 min. 3. Studies of tri-iodothyronine production from increasing amounts of thyroxine revealed that the thy...

phosphorus (p) is one of the most vital elements for all living organisms which acts as aconstituent of essential biomolecules such as nucleic acids, phospholipids, and phosphosugars,and as a major contributor to almost all metabolic reactions including photosynthesis,respiration, and energy delivery. it is one of the most needed nutrients for plant growth anddevelopment. despite high levels of...
