Fluoroalcohols such as 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) are strong inducers of protein secondary structure. Here, hydrolyzed (3,3,3-trifluoropropyl)trimethoxysilane (3F) is demonstrated to exhibit greater protein conformation inducing activity than HFIP, which is preserved when 3F is cop...

The crystal structures of two hypervalent silicon compounds (N → Si) (2-benzothiazolylthiomethyl)trifluorosilane and (N → Si) (2-benzoxazolylthiomethyl)trifluorosilane have been determined. Both molecules have similar geometrical parameters. The Si atom acquires a distorted trigonal bipyramida...

The microwave spectra of two isotopes of selenium tetrafluoride, SeF4, have been recorded between 8000 and 40 000 MHz. The rotational constants that predict the spectra are: A = 5359.935, B = 3395.079, C = 2780.431 MHz for 80SeF4 and A = 5370.448, B = 3399.281, C = 2780.416 MHz for 78SeF4.The st...

Scandium is one of the most important elements among lanthanides because of its promising applications in solid oxide fuel cells and high strength Al- Sc alloys. There are no primary mine sources for Scandium and the present supply is from stock piles and byproducts. Scarcity of reliable supply ...

The current study put the emphasis on developing a novel and environmentally friendly waste valorization process, called “acid-baking water-leaching”, to recover scandium from bauxite residue produced by the aluminum industry. In this process, bauxite residue is mixed with concentrated sulfuri...

Scandium, yttrium and lanthanides (REE) are critical raw materials in increasing demand for modern technology, so identifying and developing new sources of REE has become a pressing need. REE concentrations in acid mine drainage (AMD) are several orders of magnitude higher than those in natural ...

Bauxite residue (red mud) is a waste product of the alumina refining in the Bayer process and contains significant concentrations of critical metals, including scandium. Greek bauxite residue contains exploitable levels of scandium and is thus considered a suitable source for its production. A p...

Scandium is an important member of rare earths and always associated with other metals. A novel aminophosphonate compound di-(2-ethylhexyl)[N-(2-ethylhexyl) amino methyl] phosphonate (Cextrant 230, L) was applied for the selective extraction and recovery of scandium from sulfate medium. The extr...

ZnO was doped with Sc(III) ions to obtain a low-cost and environment-friendly antibacterial material with highly synergistic antimicrobial activity. The combination of experimental results and theoretical insights was used to describe the effect of Sc doping on the electronic and structural prop...

Using low cost spray pyrolysis technique, polycrystalline CaSO4 thin films were successfully grown on a glass substrate with a thickness of about 1 μm. Samarium doping has been performed on CaSO4 thin films to explore luminescence properties. The characterizations of these films were carried ou...

Luminescence mechanism of RE doped glasses is significant in optical devices, the glasses of compositions (80-x) P2O5-20CaSO4-(x) Sm2O3 with 0.3 ≤ x ≤ 1.5 mol% have been prepared by melt-quench method. The result of XRD patterns affirmed the amorphous nature of the samples. The structure was i...

This research work is dedicated to study structural, morphological, optical and photoluminescence properties of samarium doped calcium sulfate (CaSO4) thin films after exposure to high gamma radiations. Polycrystalline doped CaSO4 thin films have been grown on glass substrates by spray pyrolysis...

In the nitrophosphate process of fertilizer production, rare earth elements (REE) can be recovered as a REE phosphate concentrate. In this process, after digestion of apatite in concentrated nitric acid, Ca(NO3)2.4H2O is first separated by cooling crystallization and then the REE are precipitate...

Samarium (Sm) incorporated mesoporous bioactive glasses (MBG) microspheres have been prepared using the method of alginate cross-linking with Ca2 + ions. The in vitro bioactivities of Sm/MBG/alginate microspheres were studied by immersing in simulated body fluid (SBF) for various periods. The re...

The speciation of samarium (III) in chloride-bearing solutions was investigated spectrophotometrically at temperatures of 100–250 °C and a pressure of 100 bars. The simple hydrated ion, Sm3+, is predominant at ambient temperature, but chloride complexes are the dominant species at elevated tem...

The phenylsulfonylethylidene (PSE) acetal is a relatively new protecting group in carbohydrate chemistry. However, carbohydrate-derived phenylsulfonylethylidene (PSE) acetals show a different behavior in reductive desulfonylation than simple symmetrical acetals. Here we have investigated various...

Deficits in cognition and performance accompanying age-related neurodegenerative diseases such as Alzheimer's disease (AD) are closely associated with the impairment of synaptic plasticity. Here, using a mouse model of senescence-accelerated P8 (SAMP8), we reported the role of tripchlorolid...

A large body of evidence has suggested a strong association between neuroinflammation and the pathogenesis of many neurodegenerative diseases. Therefore, it is a good target for therapeutic treatment. So far, studies have proven anti-inflammatory herbal medicine and its constituents to be effect...

The influence of low-frequency electromagnetic (LF-EM) waves on microorganisms has been a subject of experimental investigations for more than two decades and the results are promising. In parallel, an interesting procedure known as biophysical-information-therapy or bioresonance therapy (BRT) w...
