A novel process for the extraction of iron, titanium, vanadium, and chromium from high-chromium vanadium-bearing titanomagnetite concentrates is proposed. This process involves several steps: partial reduction of the concentrates, magnetic separation, hydrochloric acid leaching of the titanium-bearing tailing, and alkaline desilication of the HCl l...
Production of acetone-butanol-ethanol (ABE) from cassava was investigated with a fermentation-pervaporation (PV) coupled process. ABE products were in situ removed from fermentation broth to alleviate the toxicity of solvent to the Clostridium acetobutylicum DP217. Compared to the batch fermentation without PV, glucose consumption rate and solvent ...
OBJECTIVE To explore the therapeutic potential of PnTx2-6 injected 3 times a week for 4 weeks into the intracavernosal tissue in a rat model of bilateral cavernous nerve crush injury (BCNI). METHODS Eight-week-old male Sprague-Dawley rats were randomly divided into the following 6 groups (n = 5 per group): age-matched control (normal group), BCNI (...

The histological analysis of peripheral nerve regeneration is one of the most used methods to demonstrate the success of the regeneration through nerve conduits. Nowadays, it is possible to evaluate different parameters of nerve regeneration by using histological, histochemical, immunohistochemical and ultrastructural techniques. The histochemical ...
A mesoporous boehmite (gamma-AlOOH) synthesis and vanadate (V(v)) ion adsorption and desorption on the mesoporous gamma-AlOOH were investigated. The synthesis and adsorption studies showed that the mesoporous gamma-AlOOH with a BET surface of 442 m(2) g(-1) and a pore size of 2.75 nm possessed a maximum V(v) ion adsorption capacity of 3.28 mmol g(-...
When butanol and water are mixed at a proper ratio, phase separation can occur because of the immiscibility of butanol with water. A highly concentrated aqueous butanol solution in the organic phase can be obtained. Thus, in this study, the phase separation of the permeate was examined during pervaporation (PV) of an acetone-butanol-ethanol-water s...
Corn stover is a potential feedstock for biofuel production. This work investigated physical and chemical changes in plant cell-wall structure of corn stover due to hot compressed water (HCW) pretreatment at 170-190 A degrees C in a tube reactor. Chemical composition analysis showed the soluble hemicellulose content increased with pretreatment temp...
The microstructure and phase transformational behavior of NiTi-based composites reinforced with 6 wt.% of alpha-alumina nanoparticles have been investigated. Two kinds of starting materials, elemental Ni-Ti and prealloyed austenitic NiTi, were used to prepare the composites. The samples were consolidated using a hot isostatic pressing method. The X...

Symptomatic recovery after acute vestibular neuritis (VN) is variable, with around 50% of patients reporting long term vestibular symptoms; hence, it is essential to identify factors related to poor clinical outcome. Here we investigated whether excessive reliance on visual input for spatial orientation (visual dependence) was associated with long ...

Short-chain carboxylates such as acetate are easily produced through mixed culture fermentation of many biological waste streams, although routinely digested to biogas and combusted rather than harvested. We developed a pipeline to extract and upgrade short-chain carboxylates to esters via membrane electrolysis and biphasic esterification. Carboxyl...
