Herein is the first use of a CoSn(OH)6/graphene composites as a high-performance anode in lithium ion batteries (LIBs). CoSn(OH)6 alone is found to be electrochemically active and to possess electrochemical properties that are superior to those displayed in its dehydrated form (CoSnO3). In contr...

Molecular cluster ion material, polyoxomolybdate (NH4)6[NiMo9O32] (ANM), was utilized as a new cathode material of lithium battery. Discharge capacity and cycle performance of ANM largely depend on the particle size and type of conductive additive. Nanosize ANM particles (~ 100 nm) can be easily...

Lithium-ion capacitors are considered as a promising energy storage device to combine the high energy of lithium-ion batteries and high power of supercapacitors, and it is urgently required to evaluate the energy storage capability of lithium-ion capacitors from practical perspectives. In this w...

Lithium chloride (LiCl) and 2,2‘-(1,4-phenylene)bis(2-oxazoline) (PBO) were first used as the modifier and chain extender to decrease the melting temperature and increase the molecular weight (Mη) of polyamide 6 (PA6), respectively. Then, poplar wood fiber reinforced composites based on PA6 we...

During the traditional metallurgical process of vanadium (V), an ammonium salt is often employed as the precipitator to form an ammonium vanadate, which converted into V2O5 in the subsequent calcination. Due to the restriction of ammonia emissions by the Chinese government, the vanadium-bearing ...

A new series of 6-chloro-2-(propylthio)-8,9-dihydro-7H-purine-8-caboxamide derivatives were designed, synthesized, and further evaluated for their antiproliferative activities on four human cancer cell lines (A549, MGC803, PC-3 and TE-1). The structure-activity relationships (SARs) studies were ...

The condensation reaction of 2-chloro-2-arylacetaldehyde with salicylaldehyde catalyzed by N-heterocyclic carbene (NHC) leading to 3-arylcoumarin was studied. A number of 3-arylcoumarin derivatives were obtained in good to excellent yields via this umpolung reaction. This reaction is facile and ...

The highly activated acetylenes, ethyl 4-chloro-2-oxobut-3-ynoate and ethyl 4-bromo-2-oxobut-3-ynoate, were prepared from readily available bis(trimethylstannyl)acetylene in two steps with high overall yield. An unusual ability of the former to furnish [2+2]-cycloadducts with 1,1-disubstituted a...

The effect of 14 lanthanides on the structure and the electronic system of isonicotinic acid was studied using IR (KBr), IR (ATR), Raman, UV–Vis, spectrofluorometric, elemental analysis and thermogravimetric (TG/DTG) methods. The influence of the lanthanides ions on the electronic charge distri...

In this work, new fac-Re(CO)3(PyCOOH)2Cl from isonicotinic acid ligand has been prepared. The complex was characterized by structural (single-crystal X-ray diffraction), elemental analysis and spectroscopic (FTIR, NMR, UV–vis spectroscopy) methods. DFT and TDDFT calculations were performed to o...

New pyridine derivatives were designed and synthesized as Isonicotinic acid hydrazide (INH) analogues. The synthesized compounds were evaluated for their antitubercular activity against Mycobacterium tuberculosis strain H37Rv. Ten compounds (3c, 3e-g, 5a-c, 6h, 10 and 11b) showed promising antit...

Magnetization of multi-walled carbon nano-tubes (MWCNT) was carried out by co-precipitation of Fe+2 and Fe+3 salts. The magnetization was confirmed by FTIR, FE-SEM and EDS analysis. Batch adsorption experiments were carried out to study the effect of various parameters like contact time (0–150 ...

Four new dimeric 2-(2-phenylethyl)chromones (1–4) were isolated from the agarwood of Aquilaria crassna in Laos. All structures were determined based on extensive spectroscopic methods including IR, UV, 1D and 2D NMR, ECD, and HRMS. The structures of compounds 1–3 were characterized by two C-O-...

BackgroundPain management after total hip arthroplasty is well studied. Nevertheless, there is no consensus regarding the “cocktail” to use in periarticular infiltration (PAI). Liposomal bupivacaine (LB) is a slow release local anesthetic that can be infiltrated during surgery. In this study, ...

The objective of this study was to evaluate the distribution of bupivacaine hydrochloride using magnetic resonance imaging (MRI) after electrical nerve stimulator (ENS)-guided sciatic (ScN) and femoral (FN) nerve blocks in cats. Six adult cats (body weight 4.8 ± 0.6 kg) were anesthetized with a...

ABSTRACTStudy ObjectiveTo study the effects of liposomal bupivacaine (LB) compared with bupivacaine hydrochloride with lidocaine on postoperative day 1 pain scores.

ObjectiveTo test whether neurotoxic effects of a bupivacaine liposome injectable suspension differ from those of a standard formulation of bupivacaine hydrochloride (HCl) after intraneural injection into the sciatic nerves in pigs.

Oxidative removal of the dithioacetal group of several protected sugar and 2-acylamido-2-deoxy sugar dialkyl dithioacetals with N-bromosuccinimide in 97% aqueous acetone or 1:1 (v/v) 2-methyl-2-propanol—acetone was compared with removal with mercury dichloride—mercury(II) oxide or mercury dich...

The intramolecular cyclization of O-tosyl derivatives of dithioacetals of d-ribose, d-arabinose, and d-glucose was investigated. p-Toluenesulfonylation of d-glucose diethyl dithioacetal gave 3,6-anhydro-d-glucose diethyl dithioacetal.
