optimization of the isolation methods and utilization of the sugars present in the hydrolysates obtained from pre-hydrolyses of various lignocellulosic materials for production of new chemicals and energy is currently accounted for novel methods of biorefinery all over the world. in this study, effect of temperature (90 and 100 oc), koh concentration (2, 4 and 6 %) and polyoxyethylene (80) sorb...

biochar and activated carbon, as carbon-rich porous materials, have wide environmental applications. in the present research, rice husk (rh) was used for preparation of biochar at 400, 600, and 800 °c under simple pyrolysis, physically-activated carbon with water steam, chemically-activated carbon with potassium hydroxide (koh), and physiochemically-activated carbon with koh and steam. physical...

Lanthanum hydroxide (La(OH)3) nanostructures, including elliptical nanoparticles, octahedral rods and irregular nanoparticles were prepared chemically in NaOH and KOH solutions with 10 M concentration. The obtained powders were characterized with XRD, SEM, TEM and DTA. Crystallinities, morphologies and thermal behavior of the obtained nanostructure powders were investigated under the influence ...

Several new bitopic pyrazole-containing ligands were prepared from the corresponding pyrazoles and tetrahalogen or tetratosyloxy derivatives of o-xylene and neopentane in a superbasic medium (KOH-DMSO).

We have investigated gas composition during simulated inhalation induction with sevoflurane to elucidate possible mechanisms of incidental prolonged induction times and airway irritation. Using a circle system, 8% sevoflurane in oxygen 6 litre min-1 was washed into an absorbing canister filled with fresh soda lime containing 2.9% KOH (Draegersorb, 'D') or no KOH (< 0.01%, Sofnolime, 'S'). The a...

An experiment was conducted to assess whether KOH applied as a foliar spray could mitigate the adverse effects of salt stress on plant growth and yield of sunflower plants. For this purpose, KOH @ 0, 0.5, 1.0, 1.5 and 2.0% was applied as a foliar spray to salt stressed and non-stressed sunflower plants. Foliar spray of KOH increased the growth and yield under non-stress and salt stressed condit...
