Lignocellulosic biomass was decomposed to produce crude bio-oil in water and ethanol using hydrated cerium (III) chloride as a catalyst. Use of the catalyst affected not only the yield of crude bio-oil but also the composition of bio-crude for both water and ethanol. The catalyst had a detriment...

The compound 4′-(2,4-dimethoxyphenyl)-2,2′:6′,2″-terpyridine (Mtpyr) was synthesized and investigated using X-ray single crystal structure determination, combined with Hirshfeld topology analysis of the molecular packing. In addition, Mtpyr was characterized by experimental and theoretical F...

The contribution of two starter (Lactobacillus delbrueckii and Streptococcus thermophilus) and nine non-starter (Enterococcus casselliflavus, Enterococcus faecalis, Enterococcus durans, Enterococcus gallinarum, Lactobacillus casei, Lactobacillus paracasei, Lactobacillus rhamnosus, Pediococcus ac...

Iron-sulfide and calcite containing aggregates used for preparation of asphalt mixtures underwent degradation processes under atmospheric conditions. Four locations with specific secondary mineral phases situated on highways and roads from Transylvania (Romania) were investigated. The mineralogi...

Flotation separation of the barite from calcite by adding depressant acidified water glass (AWG) and collector sodium oleate (NaOl) was investigated in this study. The micro-flotation results presented that NaOl has a good collecting ability for both barite and calcite while AWG has the selectiv...

In this paper, pectin, a polymer polysaccharide, was studied for its depression during the selective flotation separation of scheelite from calcite. Zeta potential experiment, FTIR analysis and XPS analysis were used to explain the selective depression mechanism of pectin on the two minerals. Th...

Information protection is particularly important for secure communication between parties, avoiding the leakage of secret information to unknown parties. Among various strategies used for information protection in the previous reports in the literature, security inks made from photoluminescent m...

Present research concerns the TL signal stored in chalk of the variety commercially available for writing on blackboards. Samples of this have been subjected to x-ray irradiation, the key dosimetric parameters investigated including dose and energy response, sensitivity, fading and glow curve an...

Calcium sulfate hemihydrate (CSH) with controlled crystal morphology has attracted broad interests due to its superior physical and chemical properties, as well as excellent biological performance. In this study, calcium sulfate dehydrate (CSD) was firstly synthesized via the reaction of H2SO4 a...

The feasibility of fabricating alpha calcium sulfate hemihydrate (α-CSH) whiskers by using flue-gas-desulfurization (FGD) gypsum as source materials was studied. Crystal phase- and morphology-controlled crystallization of gypsum were realized in the designed glycerol-water reaction system. l-gl...

The influence of impurities in FGD gypsum (>90% CaSO4·2H2O) on the kinetics of its transformation to α-calcium sulfate hemihydrate (α-HH, CaSO4·0.5H2O) has been seldom investigated. This work demonstrates that CaCO3 and CaSO3 in FGD gypsum retard the transformation kinetics under hydrotherma...

Calcium sulfate is in routine clinical use as a bone substitute, offering the benefits of biodegradability, biocompatibility and a long history of use in bone repair. The osteoconductive properties of calcium sulfate may be further improved by doping with strontium ions. Nevertheless, the high d...

A capillary infiltration study is presented. Three-dimensional inkjet 3D printing samples were used using calcium sulfate hemihydrate as the raw ceramic material. This manufacturing process involves some limitations such as high porosity, poor surface quality and low strength, among others. Thes...

To separate iron and sulfur in jarosite sediment by using the sieving method, firstly, the jarosite sediment is decomposed by adding calcium oxide to obtain iron hydroxide and calcium sulfate dihydrate mixed precipitation. Secondly, the calcium sulfate hemihydrate (HH) whiskers with a large diam...

We developed the 3D-printed poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/calcium sulfate hemihydrate (PHBV/CaSH) scaffolds by using fused deposition modelling (FDM) technique and then coated the scaffolds with chitosan (CS) acetic acid solution. After drying and neutralization, CS hydrogel was f...

Changes of crystal morphology and size of calcium sulfate hemihydrate (HH) by Al3+ ions, synthesized by hydrothermal method, were carried out to understand the interaction mechanism between the metal ion and crystal surface. The preferential adsorption of Al3+ on the top crystal surface was conf...

The oil industry has been drilling wells since the last century using Portland cement as a cementing basic material. There are several environmental impacts associated with the Portland cement production from the raw materials extraction to the macro impact generated by clinkerization such as th...

Alpha and beta forms of calcium sulfate hemihydrate were studied by X-Ray powder diffraction. Microstructure parameters including crystallite sizes and microstress values were determined using Williamson-Hall Plot. It has been established that alpha and beta hemihydrates are characterized by the...

We report the design and synthesis of a series of 6-(2,4-diaminopyrimidinyl)-1,4-benzoxazin-3-ones as orally bioavailable small molecule inhibitors of renin. Compounds with a 2-methyl-2-aryl substitution pattern exhibit potent renin inhibition and good permeability, solubility, and metabolic sta...

2-Aminoanthraquinone (AA), l-amino-2-methylanthraquinone (l-Am-2-MeA), and 2-methyl-l-nitroanthraquinone (2-Me-1-Na) were tested for carcinogenicity in Fischer 344 rats and B6C3F1 mice. In rats, all the 3 chemicals increased the incidence of hepatocellular neoplasms. Renal neoplasms were increas...
