Surface modification of biomaterials by photochemical immobilization and photograft polymerization to improve hemocompatibility
Frontiers of Chemical Engineering in China - Tập 4 - Trang 372-381 - 2010
Thrombus formation and blood coagulation are serious problems associated with blood contacting products, such as catheters, vascular grafts, artificial hearts, and heart valves. Recent progresses and strategies to improve the hemocompatibility of biomaterials by surface modification using photochemical immobilization and photograft polymerization are reviewed in this paper. Three approaches to mod...... hiện toàn bộ
Statistical modeling and optimization for enhanced hyaluronic acid production by batch culture of Sreptococcus zooepidemicus via the supplement of uracil

Photoluminescent properties of Sb3+-doped and (Sb3+, Eu3+) co-doped YBO3 phosphors prepared via hydrothermal method and solid-state process
Frontiers of Chemical Engineering in China - Tập 5 - Trang 429-434 - 2011
Sb3+-doped YBO3 crystals were prepared through a low-temperature hydrothermal method and a high-temperature solid-state technique, respectively. The effects of preparation methods on the morphologies and luminescent properties of YBO3 phosphors were investigated. The YBO3 crystals from the hydrothermal system look like flowers, whereas those from the solid-state process look like some agglomerates...... hiện toàn bộ
Pentachlorophenol (PCP) degradation microorganism community structure under microaeration condition
Frontiers of Chemical Engineering in China - Tập 1 - Trang 411-415 - 2007
The comparison of pentachlorophenol (PCP) degradation was conducted under micro-aeration and anaerobic condition with three series of batch experiment, results of which indicated that during micro-aeration condition co-immobilized of anaerobic granular sludge and isolated aerobic bacterial species could enhance the efficiency of PCP reduction through the synergism of aerobes and anaerobes reductiv...... hiện toàn bộ

Multiphase surfactant-assisted reaction-separation system in a microchannel reactor
Frontiers of Chemical Engineering in China - Tập 3 Số 1 - Trang 33-38 - 2009
The Lewis acid-catalyzed addition of trimethylsilyl cyanide to p-chlorobenzaldehyde in a microchannel reactor was investigated. The microchannel was integrated to promote both reaction and separation of the biphase system. FeF3 and Cu(triflate)2 were used as water-stable Lewis acid catalysts. Sodium dodecyl sulfate was incorporated in the organic-aqueous system to enhance the reactivity and to man...... hiện toàn bộ
Molecular size characterization of heavy oil fractions in vacuum and solution by molecular dynamic simulation
Frontiers of Chemical Engineering in China - - 2010
Two kinds of heavy oils were fractionated into eight fractions by Liquid-Solid Adsorption Chromatography, respectively, and samples were collected to measure properties. According to the elemental analysis, molecular weight and 1H-NMR data, average molecular structures of polycyclic aromatic and heavy resin were constructed with improved Brown-Ladner (B-L) method and several corrections. And then,...... hiện toàn bộ
Removal of dissolved oxygen from water using a Pd-resin based catalytic reactor
Frontiers of Chemical Engineering in China - - 2009
The removal of dissolved oxygen (DO) from water was studied experimentally in a Pd-resin base catalyst reactor using purified hydrogen gas as a reducing agent. The effects of various operating conditions, such as hydrogen and water flow rates, height of the catalytic resin bed, temperature, pH value and run time, on the removal of DO, had been studied extensively. The results shows that DO could b...... hiện toàn bộ
Controlled synthesis of uniform silver nanowires with high aspect ratios in aqueous solutions of gemini surfactant
Frontiers of Chemical Engineering in China - Tập 1 - Trang 221-227 - 2007
A simple solution-phase approach has been demonstrated for the large-scale synthesis of silver nanowires with diameters in the range of 15–25 nm, and lengths usually in the range of tens of micrometers. In the presence of gemini surfactant 1,3-bis(cetyldimethylammonium) propane dibromide (16-3-16), the growth of silver could be directed into a highly anisotropic mode to form uniform nanowires with...... hiện toàn bộ
Experimental studies on the influence of porosity on membrane absorption process
Frontiers of Chemical Engineering in China - Tập 1 - Trang 385-389 - 2007
Eight kinds of flat membranes with different micro-structures were chosen to carry out the membrane absorption experiments with CO2 and de-ionized water or 0.1 mol·L−1 NaOH solution as the experimental system. According to experimental results, the membrane pores shape (stretched pore and cylinder pore) and membrane thickness do not affect the membrane absorption process, and the membrane porosity...... hiện toàn bộ
