Abstract The effect of six SiO2 nanosized concentrations (0, 5, 20, 40, 60 and
80 mg L-1) and three seed prechilling treatments (control, seed prechilling
before nano SiO2 treatments, treatments of seed with nano SiO2 before
prechilling) on germination and seedling growth of tall wheatgrass (Agropyron
elongatum L.) were studied. Results indicated that application of SiO2
nanoparticles significantl... hiện toàn bộ

Abstract The study investigated the suitability of waste rubber powder (WRP) use
as filler in adhesive formulation for plywood application. Melamine Urea
Formaldehyde (MUF) was employed as resin for formulating the wood adhesive. To
improve chemical properties and bonding quality of adhesive, WRP was treated by
different chemicals like 20% nitric acid, 30% hydrogen peroxide and acetone
solution. T... hiện toàn bộ

Abstract Application of 1-butyl-3-metyhlimidazaolium hexafluorophosphate
([C4mim][PF6]), in the extraction of rubidium and cesium from brine solutions
using 1,4,7,10,13,16-hexaoxacyclooctadecane (18C6) as extractant was
investigated. Parameters that affect the extraction including pH of aqueous
phase, equilibration time, dosage of the ionic liquid, phase ratio,
concentration of 18C6 were studied. ... hiện toàn bộ
Abstract The aim of this study was to determine the adsorption capacity of the
smectite clays (from the overburden of the lignite deposit in Belchatow) for two
anionic dyes, i.e. Reactive Blue 81 (RB-81) and Direct Blue 74 (DB-74).
Additionally, the influence of the thermal and chemical (acid and alkali) clay
modifications on the amount of bonded dyes was investigated. The adsorption
capacity of t... hiện toàn bộ

Abstract Gallium (Ga) is considered an important element in the semiconducting
industry and as the lifespan of electronic products decrease annually
Ga-containing effluent has been increasing. The present study investigated the
use of biodegradable polymer powders, crab shell and chitosan, in the removal of
Ga(III) ions from aqueous solution. Ga(III) biosorption was modeled to

Electrically conductive acrylic pressure-sensitive adhesives containing carbon
black Acrylic pressure-sensitive adhesives (PSA) are non electrical conductive
materials. The electrical conductivity is incorporated into acrylic
self-adhesive polymer after adding electrically conductive additives like carbon
black, especially nano carbon black. After an addition of electrical conductive
carbon black,... hiện toàn bộ
