New type 2,5-di(2-thienyl)pyrrole derivative namely 4-amino-N-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzamide (HKCN) have been synthesized via reaction of 1,4-di(2-thienyl)-1,4-butanedione and p-aminobenzoyl hydrazide. Using hydrazide instead of amine not only increases product yield but also im...

New experimental results are presented for the solubility of carbon dioxide, hydrogen sulfide in the ionic liquid 1-octyl-3-methylimidazolium hexafluorophosphate ([C8mim][PF6]) at temperatures range from (303.15 to 353.15) K and pressures up to about 2 MPa. The solubility of the mixture of CO2/H...

Phthalic acid esters (PAEs) are a group of recalcitrant and hazardous organic compounds that pose a great threat to both ecosystem and human beings. A novel endophytic strain YJB3 that could utilize a wide range of PAEs as the sole carbon and energy sources for cell growth was isolated from Cann...

This review article presents different fabrication procedures (under the headlines of solvothermal routes, aerosol methods, solution methods and thermolysis), and applications (photocatalytic degradation, ablation of cancer cells, electrode material in lithium ion batteries and in gas sensing, o...

Sherwood Copper’s Minto Mine processes a high grade copper–gold deposit in Yukon, Canada. The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides. In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover coppe...

Selective oxidation of sulfides to sulfoxides and sulfones with hydrogen peroxide under organic solvent-free conditions was demonstrated by the MWW-type titanosilicate zeolite catalyst. Sulfides were oxidized smoothly to give sulfoxides with good selectivities at ambient temperature using 1.0–1...

Naphthenic acids (NAs) are naturally occurring organic acids present in crude oil and bitumen as contaminants. Their presence in the crude oil greatly reduces the quality and price of crude oil. NAs also causes corrosion in the production and processing facilities. They are quantified in the pet...

Purification of aqueous stream of sulphate containing copper ions (Cu2 +) has been studied by reactive extraction technique. Dissolved Cu2 + ions are removed from the aqueous solution with the help of tri-n-butyl phosphate (TBP) as a promising extractant with benzene used as a diluent to decreas...

Cinnamic acid derivatives are known antifungal, antimicrobial, antioxidant, and anticancer compounds. We have developed a facile and mild methodology for the synthesis of (E)-cinnamate derivatives using a modified Steglich esterification of (E)-cinnamic acid. Using acetonitrile as the solvent, r...

The cyanide metabolite 2-aminothiazoline-4-carboxylic acid (ATCA) is a promising biomarker for cyanide exposure because of its stability and the limitations of direct determination of cyanide and more abundant cyanide metabolites. A simple, sensitive, and specific method based on derivatization ...

2-aminothiazoline-4-carboxylic acid (ATCA) is a hydrogen cyanide metabolite that has been found to be a reliable biomarker of cyanide poisoning, because of its long-term stability in biological material. There are several methods of ATCA determination; however, they are restricted to extraction ...

In this paper, we proposed an innovative hydrophilic interaction dispersive solid-phase extraction (HI-d-SPE) protocol suitable for the isolation of the potential cyanide intoxication marker, 2-aminothiazoline-4-carboxylic acid (ATCA), from such complicated matrix as post-mortem blood. To create...

In this paper, the optimized synthesis and detailed characterization of novel imprinted material for selective extraction of 2-aminothiazoline-4-carboxylic acid (ATCA) were described. The prepolymeric system contained 1-allyl-2-thiourea and ethylene glycol dimethacrylate in methanol, tetrahydrof...

ObjectivesThe aims of this study were threefold:first, to assess the dietary fatty acid (FA) intake and blood FA status in Malaysian patients on hemodialysis (HD); second, to examine the association between dietary FA intakes and blood FA profiles in patients on HD; and third, to determine wheth...

Schistosomiasis is on the top list of endemic diseases in sub-Saharan Africa. Praziquantel is the drug of choice for treatment of human schistosomiasis. Yet, the sole dependence on the drug raises concerns about the potential for increased drug resistance, which would subsequently result in sear...

Garnet-type solid-state electrolytes (SSEs) are very promising due to their high ionic conductivities at room temperature and high stability against Li metal. However, the poor garnet/Li interfacial contact caused by Li2CO3 surface contaminant can lead to lithium dendrite growth and the performa...

Bone is a dynamic tissue that is constantly remodelled by bone resorbing osteoclasts and bone forming osteoblasts, respectively. A breakdown in the remodelling process underlies several bone diseases such as osteoporosis. Unsaturated fatty acids (UFAs) have been shown to have beneficial effects ...

The inorganic–organic salts (H2TMDP)3(Bi2I9)2 (1), (H2TMDP)2(Bi4I16)·2EtOH (2), (H2TMDP)2(Bi6I22)·2EtOH (3), and (H2TMDP)2(Bi6I22) (4) were synthesized and structurally characterized from the solvothermal reaction of 1,3-bis-(4-piperidyl)propane (TMDP) and BiI3 by adjusting the relative ratio...
