Structure controlling and process scale-up in the fabrication of nanomaterials

Chunzhong LI,

《化学科学与工程前沿（英文）》 2010年 第4卷 第1期   页码 18-25 doi: 10.1007/s11705-009-0305-3

摘要： Nanotechnology is already having a significant commercial impact, and will very certainly have a much greater impact in the future. The research on process engineering and scale-up will be very important for the commercial production and application of nanomaterials, because the properties and structure of nanomaterials are not only determined by the nucleation and growth process, but also strongly affected by the engineering properties, such as the mixing, the heat and mass transfer, and also the distribution of temperature, concentration, etc. This paper will present some research work in our laboratory on the fabrication of nanomaterials. Based on the chemical engineering principle and methods, many kinds of novel nanomaterials can be synthesized and their structure can be easily controlled through adjusting the parameters of the fluid mixing, and the distribution of temperature, residence time and concentration, etc. By using the micro-mixing, heat and mass transfer and reaction control methods, the host-guest nanocomposites have been assembled and assumed as the novel electroanalytical sensing nanobiocomposite materials. Based on the principles of chemical engineering, the manufacturing technologies for magnetic powders, calcium carbonate, and titanium dioxide have been developed for commercial-scale production, and the largest production scale has reached 15 kt/year.

Chemical characteristics of fine particulate matter emitted from commercial cooking

Bing PEI,Hongyang CUI,Huan LIU,Naiqiang YAN

《环境科学与工程前沿（英文）》 2016年 第10卷 第3期   页码 559-568 doi: 10.1007/s11783-016-0829-y

摘要： The chemical characteristics of fine particulate matter (PM ) emitted from commercial cooking were explored in this study. Three typical commercial restaurants in Shanghai, i.e., a Shanghai-style one (SHS), a Sichuan-style one (SCS) and an Italian-style one (ITS), were selected to conduct PM sampling. Particulate organic matter (POM) was found to be the predominant contributor to cooking-related PM mass in all the tested restaurants, with a proportion of 69.1% to 77.1%. Specifically, 80 trace organic compounds were identified and quantified by gas chromatography/mass spectrometry (GC/MS), which accounted for 3.8%–6.5% of the total PM mass. Among the quantified organic compounds, unsaturated fatty acids had the highest concentration, followed by saturated fatty acids. Comparatively, the impacts of other kinds of organic compounds were much smaller. Oleic acid was the most abundant single species in both SCS and ITS. However, in the case of SHS, linoleic acid was the richest one. ITS produced a much larger mass fraction of most organic species in POM than the two Chinese cooking styles except for monosaccharide anhydrides and sterols. The results of this study could be utilized to explore the contribution of cooking emissions to PM pollution and to develop the emission inventory of PM from cooking, which could then help the policy-makers design efficient treatment measures and control strategies on cooking emissions in the future.

《农业科学与工程前沿（英文）》 2016年 第3卷 第2期   页码 137-146 doi: 10.15302/J-FASE-2016098

摘要： Egyptian broomrape (EB), , is a devastating root parasite, causing enormous crop losses around the world. Maize has the potential to influence the growth of other plants through releasing certain allelochemicals and is able to induce germination of at least three broomrape species. To determine whether maize could be used as a trap crop for EB, 10 maize cultivars were tested for their ability to induce EB germination. The results showed that maize cultivars can induce EB germination, and that germination rates in a cut-root experiment and a hydroponic experiment were consistent. Maize cvs Changcheng 799 and Zhengdan 958 induced the highest EB germination rates, while cvs Luyu 13 and Zhengyu 203 were the least effective. These four maize cultivars were further studied in a pot experiment. Rhizosphere soil, rhizosphere soil extracts, root extracts and shoot extracts from these cultivars were all able to induce EB germination, with cv. Changcheng 799 inducing the highest germination rates. Root extracts generally induced higher germination rates than shoot extracts. It is suggested that Changcheng 799 could be planted as a trap crop for control of EB.

摘要： Considering the fact that customers of large commercial buildings have the characteristics of the higher density and randomness, this paper presented an air-conditioning cooling load prediction method based on weather forecast and internal occupancy density. The multiple linear feedback regression model was applied to predict, with precision, the air conditioning cooling load. Case analysis showed that the largest mean relative error of hourly and the daily predicting cooling load maximum were 18.1% and 5.14%, respectively.

《化学科学与工程前沿（英文）》 2007年 第1卷 第4期   页码 327-331 doi: 10.1007/s11705-007-0059-8

摘要： In recent years, resins prepared via molecular imprinting technology have received considerable attention owing to their recognition and selective adsorption. This paper deals with the comparative investigation between a uranyl sulphate imprinted ion-exchange based on self-assembling molecular imprinting technology and two kinds of commercial uranium resins (the medium pore resin D263 and strong base resin 201×7). The studies were focused on their kinetics performance, adaptability toward pH, and performance of saturation and elution in laboratory-scale column. The results show that the imprinted ion exchange resin has the fast kinetics, high adaptability toward pH, and good adsorption and elution performance.

《能源前沿（英文）》 2015年 第9卷 第2期   页码 211-216 doi: 10.1007/s11708-015-0351-0

摘要： With the latest introduction of the demand side management (DSM) in smart grids, the power distribution units are able to modify the load schedules of the consumers. This involves a co-operative interaction of the utility and the consumers so as to achieve customer load modifications in which the customer, utility and society all are benefited. The interaction is performed with the help of the devices known as the smart meter. This paper shows the use of game theory and logical mathematical expressions in order to achieve the objectives. The objectives are to minimize the peak to average ratio (PAR) and the energy cost. The outcome of the game between supplier and customers helps to shape the load profile. The design proposed in this paper is very user-friendly and is based on simple logarithmic programming computations. In this paper, residential, commercial and industrial types of loads are taken into account. A basic 24 h load schedule along with the fluctuating prices at each hour of the day is forecasted by the supplier of the various shiftable and non-shiftable loads and then that schedule is conveyed to the user. The users are encouraged to shift their high load devices to off-peak hours which will not only reduce their electricity costs but also substantially reduce the PAR in the load demand.

《医学前沿（英文）》 2008年 第2卷 第4期   页码 406-409 doi: 10.1007/s11684-008-0078-y

摘要： More and more studies have reported the usefulness of repetitive transcranial magnetic stimulation (rTMS) in the treatment of stroke patients. This article is to explore if rTMS can cause changes of such chemical substances as N-acetylaspartate (NAA), choline (Cho) and creatine (Cr) in the surrounding area of experimental intracerebral hematoma of rabbits. A total of 36 rabbits were randomly divided into 3 groups: a control group (group A), a sham rTMS group (group B) and an rTMS group (group C). The experimental intracerebral hemorrhage (ICH) was induced by intracerebral injection of self-body blood of the animals in groups B and C, while those of the group A serving as controls were injected with normal saline. The rabbits of groups B and C were treated with sham and real rTMS, respectively, but those of group A were not. The contents of chemical substances including NAA, Cho and Cr in the perihematomal brain tissues were measured by using H-magnetic resonance spectroscopy (H-MRS) 12 hours, 72 hours, 1 week and 2 weeks after the experimental ICH was induced. The results show that the contents of NAA, Cr and NAA/Cr ratio were decreased significantly, but Cho, Cho/Cr increased significantly in groups B and C ( < 0.01) as compared against those in group A. A comparison between the groups B and C revealed that the contents of NAA, Cr, NAA/Cr were higher, but Cho and Cho/Cr were significantly lower in group C than those in group B ( < 0.01). It is concluded that rTMS could result in changes of the chemical substance contents in perihematomal brain tissues, which leads to neuroprotective effects in the brain.
