The role of copper element has been an increasingly relevant topic in recent years in the fields of human and animal health, for both the study of new drugs and innovative food and feed supplements. This metal plays an important role in the central nervous system, where it is associated with glutamatergic signaling, and it is widely involved in inflammatory processes. Thus, diseases involving copper(Ⅱ) dyshomeostasis often have neurological symptoms, as exemplified by Alzheimer's and other diseases(such as Parkinson's and Wilson's diseases). Moreover, imbalanced copper ion concentrations have also been associated with diabetes and certain types of cancer, including glioma. In this paper, we propose a comprehensive overview of recent results that show the importance of these metal ions in several pathologies, mainly Alzheimer's disease, through the lens of the development and use of copper chelators as research compounds and potential therapeutics if included in multi-target hybrid drugs. Seeing how copper homeostasis is important for the well-being of animals as well as humans, we shortly describe the state of the art regarding the effects of copper and its chelators in agriculture, livestock rearing, and aquaculture, as ingredients for the formulation of feed supplements as well as to prevent the effects of pollution on animal productions.

Optical inline analysis and monitoring of particle size and shape distributions for multiple applications: Scientific and industrial relevance

引用

Chinese Journal of Chemical engineering 2019年第2期27卷 257-277页

作者： J?rn Emmerich Qiao Tang Yundong Wang Peter Neubauer Stefan Junne Sebastian Maa? bioprocess engineering department of biotechnology Technische Universit?t Berlin SOPAT GmbH The State Key Laboratory of Chemical engineering Department of Chemical Engineering Tsinghua University

Particles occur in almost all processes in chemical and life sciences. The particle size and shape influence the process performance and product quality, and in turn they are influenced by the flow behavior of the particles during production. Monitoring and controlling such characteristics in multiphase systems to obtain sufficient qualities will greatly facilitate the achievement of reproducible and defined distributions. So far, obtaining this information inline has been challenging, because existing instruments lack measurement precision, being unable to process overlapping signals from different particle phases in highly concentrated multiphase systems. However, recent advances in photo-optics made it possible to monitor such features(particle size distribution(PSD), aspect ratio and particle concentration) with advanced image analysis(IA) in real-time. New analysis workflows as well as single feature extractions from the images using multiple image analysis algorithms allowed the precise real-time measurements of size, shape and concentration of particle collectives even separated from each other in three phase systems. The performances, advantages and drawbacks with other non-photo-optical methods for assessing the particle size distribution are compared and discussed.

处于极端环境下的中高温工业废气中CO2的固定和转化是一项兼具重要科学意义和挑战性的任务.Ga2O3是一种稳定的p-族化合物在热催化高温CO2废气中表现出惊人的活性,但我们其仍不清楚其反应机理.在本工作中,我们用密度泛函理论研究了11种不同Ga2O3表面的CO2的吸附和活化过程.电荷转移和化学键分析表明,在基底表面Ga阳离子和O阴离子之间强大的协同效应驱动下,同时出现了电子增加和电子减少两种不同的CO2活化机制.与单一活性位点相比,这种Ga-O协同作用提高了CO2的活化效率,其中CO2δ+阳离子比CO2δ–阴离子更容易捕获H原子.据我们所知,这种双重活化机制以前从未被报道过,尤其是对于p族催化剂.我们的发现为中高温CO2废气排放的直接催化转化提供了新的见解,并为处理CO2尾气的工业级催化剂的设计提供了合理的策略.

Inocula selection in microbial fuel cells based on anodic biofilm abundance of Geobacter sulfurreducens

Chinese Journal of Chemical engineering 2016年第3期24卷 379-387页

Microbial fuel cells （MFCs） rely on microbial conversion of organic substrates to electricity. The optimal perfor- mance depends on the establishment of a microbial community rich in electrogenic bacteria. Usually this micro- bial community is established from inoculation of the MFC anode chamber with naturally occurring mixed inocula. In this study, the electrochemical performance of MFCs and microbial community evolution were eval- uated for three inocula including domestic wastewater （DW）, lake sediment （LS） and biogas sludge （BS） with varying substrate loading （Lsub） and external resistance （Rext） on the MFC. The electrogenic bacterium Geobacter sulfurreducens was identified in all inocula and its abundance during MFC operation was positively linked to the MFC performance. The IS inoculated MFCs showed highest abundance （18% ± 1%） of G. sulfurreducens, maximum current density [Imax = （690 ± 30） mA.m 2] and coulombic efficiency （CE = 29% ±1%） with acetate as the substrate./max and CE increased to （1780 ± 30） mA.m-2 and 58%± 1%, respectively, after decreasing the Rext from 1000 Ωto 200 Ω, which also correlated to a higher abundance ofG. sulfurreducens （21% ±0.7%） on the MFC anodic biofilm. The data obtained contribute to understanding the microbial community response to Lsub and Roy, for of timizing electricity eneration in MFCs.

The effect of aeration conditions and pH control on the progress and efficiency of beet molasses vinasse biodegradation was investigated during four batch processes at 38°C with the mixed microbial culture composed of Bifidobacterium,Lactobacillus,Lactococcus,Streptococcus,Bacillus,Rhodopseudomonas,and *** four processes were carried out in a shake flask with no pH control,an aerobic bioreactor without mixing with no pH control,and a stirred-tank reactor （STR） with aeration with and without pH control,*** experiments were started with an initial pH *** highest efficiency of biodegradation was achieved through the processes conducted in the STR,where betaine （an organic pollutant occurring in beet molasses in very large quantities） was completely degraded by the *** process with no pH control carried out in the STR produced the highest reduction in the following pollution measures：organic matter expressed as chemical oxygen demand determined by the dichromatic method ＋ theoretical COD of betaine （COD sum,85.5%）,total organic carbon （TOC,78.8%） and five-day biological oxygen demand （BOD 5,98.6%）.The process conditions applied in the shake flask experiments,as well as those used in the aerobic bioreactor without mixing,failed to provide complete betaine *** a consequence,reduction in COD sum,TOC and BOD 5 was approximately half that obtained with STR.
