Although biological pretreatment has the advantages of being environmentally friendly and having low-energy consumption, it usually requires a relatively long incubation time. In this study, a novel combined pretreatment with white-rot fungus and alkali at near room-temperature for saccharification of corn stalks was investigated to speed up the biological process. Biological pretreatment with ...

Influence of alkali and temperature were studied on dyeing of cotton fabric with bi-functional Fluoro Chloro Pyrimidene (FCP), bi-functional Monochlorotriazine-Vinyl Sulphone (MCT-VS) and mono functional Monochlorotriazine (MCT) reactive dyes. For this analysis single joursey knitted fabrics were taken. The selected dyestuffs were Drimarene Yellow K-2R (FCP), Drimarene Red CI-5B (MCT-VS) and Dr...

High-sensitivity radioluminescence (RL) and thermoluminescence (TL) measurements were carried out on samples of natural leucite (with 2.95% of Na2O) from Campania Vessa (Italy). Samples were annealed to modify the charge compensation through alkali metal self-diffusion and to produce luminescence centres. High-temperature powder diffraction, scanning electron microscopy and chemical analyses we...

A significant tin deposit has been identified in the northeast part of the Late Proterozoic Arabian Shield. Cassiterite-topaz-quartz greisens are distributed over 16 km2 in flat-topped cupolas of a highly evolved, zinnwaldite-bearing alkali-feldspar granite which composes part of the silsilah ring complex (lat 26"06'N, long 4240'E). The 587 m.y. old alkali-feldspar granite is overlain by a cara...

BACKGROUND Alkali-burned corneas can seldom heal properly to restore corneal transparency. Treatment of this severe disorder of the ocular surface remains a challenge. AIM OF THE WORK was to investigate whether systemically transplanted bone marrow mesenchymal stem cells (BM-MSCs) can promote corneal wound healing after alkali burn. MATERIAL AND METHODS Thirty five male New Zealand rabbits ...

PURPOSE The present study was conducted to investigate healing of alkali-burned corneas in MRL/MpJ (MRL) mice. METHODS Gross, clinical, and histologic criteria were used to compare healing of alkali-burned corneas in MRL and control C57BL/6J (B6) mice. Effects of neutrophil depletion of B6 mice and allogeneic reconstitution of B6 mice with MRL bone marrow on wound healing were evaluated. Gene...

Porous carbon spheres with unique structures and morphologies are prepared from energetic carbon precursors, alkali propiolates, via ultrasonic spray pyrolysis. Aerosolized liquid droplets containing alkali propiolates act as microreactors that confine the thermal decomposition of energetic precursors and lead to the formation of several unprecedented carbon morphologies.

A remarkable orbital quadrupole magnetic resonance, so-called twist mode, is predicted in alkali metal clusters where it is represented by Ipi = 2(-) low-energy excitations of valence electrons with strong M2 transitions to the ground state. We treat the twist by both macroscopic and microscopic ways. In the latter case, the shell structure of clusters is fully exploited, which is crucial for t...
