Electrochemical treatment of diluted cyanide aqueous wastes
Journal of Chemical Technology and Biotechnology - Tập 80 Số 5 - Trang 565-573 - 2005
AbstractThe electrochemical oxidation of diluted cyanide aqueous wastes has been
studied in a single compartment electrochemical flow cell. It has been
determined that the anode material influences greatly the process's performance.
Boron doped diamond and PbO2 anodes can oxidize these wastes in the presence of
both sulfate or chloride anions. On the contrary, dimensional stable anodes
cannot oxid...
Adsorption behaviour of metal ions on imprinted chitosan resin
Journal of Chemical Technology and Biotechnology - Tập 76 Số 2 - Trang 191-195 - 2001
AbstractA new method for preparation of metal ion imprinted chitosan resin,
which can considerably enhance the adsorption capacity and selectivity of the
metal ion is presented in this paper. The conditions influencing the preparation
of chitosan imprinted resin such as the cross‐linking agent, epichlororohydrin
and ethylene glycol diglycidyl ether, and metal ion concentration are optimized.
The c...
Preparation of a surface molecular‐imprinted adsorbent for Ni2+ based on Penicillium chrysogenum
Journal of Chemical Technology and Biotechnology - Tập 80 Số 4 - Trang 439-444 - 2005
AbstractA new chitosan molecular‐imprinted adsorbent was prepared from the
mycelium of waste biomass. The results showed that an adsorbent using
Penicillium chrysogenum mycelium as the core material was better than one
derived from peanut coat. The adsorption capacity of the surface‐imprinted
adsorbent for Ni2+ was enhanced by increasing the chitosan concentration in the
imprinting process. Epichl...
Chemoenzymatic synthesis: a strategy to obtain xylitol monoesters
Journal of Chemical Technology and Biotechnology - Tập 84 Số 7 - Trang 957-960 - 2009
AbstractBACKGROUND: Fatty acid sugar esters are used as non‐ionic surfactants in
cosmetics, foodstuffs and pharmaceuticals. In particular, monoesters of xylitol
have attracted industrial interest due to their outstanding biological
activities. In this work, xylitol monoesters were obtained by chemoenzymatic
synthesis, in which, first, xylitol was made soluble in organic solvent by
chemo‐protecting...
Conversion of glycerol to dihydroxyacetone over Au catalysts on various supports
Journal of Chemical Technology and Biotechnology - Tập 95 Số 4 - Trang 1153-1162 - 2020
AbstractBACKGROUNDGlycerol, which is a coproduct of biodiesel production, has
been identified as a key platform compound for producing various valuable
chemicals. The selective catalytic oxidation of glycerol to dihydroxyacetone is
very attractive.RESULTSA series of Au catalysts supported on metallic oxides,
i.e. ZnO, CuO, Al2O3, Fe2O3 and NiO, were studied for selective catalytic
oxidation of gly...
Absorption of CO2with supported imidazolium-based ionic liquid membranes
Journal of Chemical Technology and Biotechnology - Tập 90 Số 8 - Trang 1537-1544 - 2015
Cell‐based aqueous two‐phase systems for therapeutics
Journal of Chemical Technology and Biotechnology - Tập 95 Số 1 - Trang 8-10 - 2020
AbstractCell‐based aqueous two‐phase system technologies present an emerging and
promising translational tool for the development of next‐generation therapeutic
applications. Advantages such as biocompatibility, scalability and ease of
implementation confirm this possibility. The aim of this perspective article is
to present a brief, process‐oriented analysis of cell‐based aqueous two‐phase
system...
Characterization of polymer‐polymer aqueous two‐phase system droplets for 3D culture future applications
Journal of Chemical Technology and Biotechnology - Tập 98 Số 8 - Trang 1888-1895 - 2023
AbstractBACKGROUNDCell‐based high‐throughput platforms using aqueous two‐phase
systems (ATPS) have led to the construction of 3D cultures using ATPS in which
stem cells are confined into polymer–polymer droplets, giving rise to viable
spheroids for their further proliferation and differentiation. This work aims to
characterize polymer–polymer ATPS droplet generation based on diameter size,
morphol...
Novel approach for neuronal stem cell differentiation using aqueous two‐phase systems in 3D cultures
Journal of Chemical Technology and Biotechnology - Tập 96 Số 1 - Trang 8-13 - 2021
AbstractStem cell therapy has emerged as a promising alternative for replacing
lost cells involved in neurodegenerative diseases. High efficiency of
differentiation and full cell viability are actual challenges to achieve the
translation of cell therapies to the clinic. To address this, the construction
of aqueous two‐phase systems in three‐dimensional (ATPS‐3D) cultures has been
proposed. This te...
