With the increased demands of energy density boosting electrochemical performance rechargeable alkali metal ion batteries, safe operation second batteries is attracting much attention and needs to be especially considered during their further development, which essential in view well-known fire incidents lithium-ion batteries. These dangerous events are as a consequence exothermic chemical reac...

Alkaline phosphatase serves both as a model enzyme for studies on the mechanism and kinetics of phosphomonoesterases and as a reporter in enzyme-linked immunosorbent assays (ELISAs) and other biochemical methods. The tight binding of the enzyme to its inorganic phosphate product leads to strong inhibition of catalysis and confounds measurements of alkaline phosphatase activity. We have develope...

A cationic surfactant-selective electrode for sensitive analysis of cationic surfactant has been developed by using a plasticized poly (vinyl chloride) membrane based on nanocomposite cation exchanger polypyrrole zirconium titanium phosphate. The electrode is excellently selective for the cetyl trimethyl ammonium bromide (CTAB) ion over inorganic ions and other cationic surfactants. The membran...

Thiolo thiophosphate analogues of isopentenyl diphosphate (IPP), dimethylallyl diphosphate (DMAPP), geranyl diphosphate (GPP), farnesyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP) were synthesized. Inorganic thiopyrophosphate (SPP(i)) was prepared from trimethyl phosphate in four steps. The tris(tetra-n-butylammonium) salt was then used to convert isopentenyl tosylate to (S)-isopen...

A newly synthesized family of materials prepared with surfactant as organic template were tested for the extraction of polycyclic aromatic hydrocarbons (PAHs) from water, using pyrene (Pyr) and benzo[a]pyrene (B[a]P) as PAHs representatives. Particular attention was paid to the evaluation of the recovery factors with dichloromethane as eluent in order to estimate their potential as adsorbing so...

Due to the neurotoxicity of organophosphate (OP) pesticides and nerve agents synthesized as military or terror agents, their safe destruction and disposal is of considerable current importance. A representative OP, trimethyl phosphate (TMP), was adsorbed onto NaX zeolite, two mesoporous modifications, and a low-silica X zeolite. The nucleophilic chemical reactions of TMP with the zeolites were ...

Tertiary ethers are formed in a reaction between alcohols and alkenes. They are used in gasoline to enhance its burning and to reduce harmful exhaust emissions. They also have high octane rating, which is beneficial for gasoline blending. Regulations in regard to fuel composition and exhaust emissions are tightening and new, cleaner burning high octane gasoline components are of wide interest. ...

Abstract Culture supernatants of Basfia succiniciproducens derived from the industrial production succinic acid exhibit an intense nutty, root vegetable‐like, buttery and sourish smell. By means headspace‐gas chromatography‐mass spectrometry‐olfactometry (HS‐GC‐MS‐O), 14 odour‐active compounds were perceived identified using two GC‐columns different polarity comparison retention indices mass sp...

A small molecule receptor that mimics the HP1 chromodomain's affinity for trimethyl lysine has been identified from a dynamic combinatorial library. Discrimination for trimethyl lysine over the lower methylation states parallels that of the native protein receptor. These studies demonstrate the feasibility of small molecule receptors as potential sensors for protein post-translational modificat...
