| 1 | 竹格填料与PVC填料在冷却塔中的节能效率与环境影响研究显示文摘本研究针对电厂冷却塔领域的能源成本及水资源短缺等问题,系统分析了新兴竹格淋水填料的节能效率及对环境影响等特性,并与市场占有率最高的PVC填料进行了对比。结果发现,竹格填料的阻力性能优于PVC填料,而热力性能较差;在6个月实际应用试验中,使用竹格填料的电厂,比使用PVC填料节约529.2 t标煤;生命周期评价结果显示,PVC填料的能源需求总量(CED)为3420 MJ,竹格填料的能源需求总量仅为561 MJ,比PVC填料减少6倍;从环境影响指数(BEES)看,PVC填料替换为竹格填料后,各主要影响指标降低了1.5~10.5倍不等。结果表明,竹格填料是替换PVC填料的良好选择,具有很好的推广价值。 | 马欣欣 陈礼生 费本华 鲁继平 Liping Cai Changlei Xia Su Shiung Lam | 2021 | 世界竹藤通讯2021，19，2： | 3 |
| 2 | In-Situ Chemosynthesis of ZnO Nanoparticles to Endow Wood with Antibacterial and UV-Resistance Properties显示文摘Hybrid wood materials have attracted considerable attention because they have combined advantages of both wood and inorganic compounds. This work investigated the microstructural morphology, thermal stability, ultraviolet(UV) stability, and antibacterial property of composites made from wood/ZnO hybrid materials through a facile in-situ chemosynthesis methods. The X-ray diffraction(XRD) and thermogravimetric analysis(TGA) results indicated that the synthesized ZnO particles had an average grain size of about 10.8 nm. The scanning electron microscopy(SEM) observations showed that ZnO nanoflowers self-assembled with nanosheets were presented in wood cell lumens and increased with increasing Zn^(2+)concentrations. ZnO nanoparticles were also generated in the wood cell wall, which was confirmed by the results of energy-dispersive spectroscopy(EDS). The TGA tests also indicated that the thermal stability of wood/ZnO hybrid materials was improved after the formation of ZnO inorganic particles. Finally, the results of antibacterial efficacy tests and UV resistance tests revealed that ZnO nanoparticles showed a promising future as antimicrobial agents against Escherichia coli(E.coli) and UV resistance agents for wood protection. | Youming Dong Yutao Yan Huandi Ma Shifeng Zhang Jianzhang Li Changlei Xia Sheldon Q.Shi Liping Cai | 2017 | Journal of Materials Science & Technology2017，33，3： | 2 |
| 3 | Is engineered wood China’s way to carbon neutrality?显示文摘China emits more than 25%of the world’s carbon dioxide(http://gffzz19a57d7abdd14508subqfuppfovvw65bv.ffgz.tsg.suse.edu.cn/co2-emissions),and in December 2021 the country’s daily carbon trading volume hits a new highest record.Together with the EU and USA,China bears a great responsibility to limit global warming to 2℃,and therefore recently launches a plan to be carbon-neutral be-fore 2060(http://gffzz19a57d7abdd14508subqfuppfovvw65bv.ffgz.tsg.suse.edu.cn/co2-emissions).However,its rapid urbanization challenges this initiative as the boom-ing building and construction industry constitute more than 1/3 of the total energy consumption,which undesirably in-creases carbon emissions(IEA,2019;Duan et al.,2021).Although China has built five new nuclear power stations and closed down more than 1000 coal-fired power plants,it is still highly insufficient to meet the country’s goal to be carbon-neutral(http://gffzzf2b30595ab3b4dcfsubqfuppfovvw65bv.ffgz.tsg.suse.edu.cn/countries/china/). | Christian Sonne Changlei Xia Su Shiung Lam | 2022 | Journal of Bioresources and Bioproducts2022，7，2： | 1 |

| 5 | Plastic crisis underscores need for alternative sustainable-renewable materials显示文摘The current global plastic crisis is triggered by several factors including increased costs of petrochemical feedstock and Covid-19 disruption of the transport sector(Yuan et al.,2021).This disruption of world-wide supply chains of polyethylene,polypropylene and other petroleum-based hydrocarbon chemicals has significantly increased shortage and prices of plastics in for example Europe over the last year,hence calling for sustainable alternatives to conventional plastics(WMW,2021,European Plastic Manufacturers sound the Alarm Bell on Supply Chain Disruption,Waste Management World.).This is critical due to extensive use of the non-biodegradable personal protective equipment(PPE)masks in the current pandemic,which might be even worse than the shortage of polyolefins at the moment(Deng et al.,2022). | Su Shiung Lam Changlei Xia Christian Sonne | 2022 | Journal of Bioresources and Bioproducts2022，7，3： | 1 |
| 6 | Microplastics pollution:Economic loss and actions needed显示文摘Microplastics originate from plastic bottles of water and soft drink,plastic bags,tire wear,plastic agricultural mulches and 3D printing[1,2].These small fragments of wastes being 1μm to 5 mm pollute the environment and threaten human health and ecosystem services including crops and others,leading to economic losses[1–3].It is predicted that by 2030,plastic productions will be leading environmental pollution in terms of carbon footprint and toxic chemicals[4],making U.S.the world’s largest plastic waste generator[5].Based on reports from the United Nations Environment Assembly(UNEA)and the United Nations Environmental Program(UNEP),plastics in the environment annually burden the global economy by$19 billion,causing concerns for long-term ecological sustainability and the Global Goals[6].It is reported that about 8.3 billion tons of plastic waste have been created,leading to 4.9 billion tons discarded through landfilling globally[7],causing a yearly financial loss of more than$13 billion[8]. | Changlei Xia Liping Cai Su Shiung Lam Christian Sonne | 2023 | Eco-Environment & Health2023，2，2： | 0 |
| 7 | Microwave torrefaction of empty fruit bunch pellet:Simulation and validation of electric field and temperature distribution显示文摘Microwave simulation is significant in identifying a reactor design allowing the biomass to be heated and processed evenly.This study integrated the radio frequency and transient heat transfer modules to simulate the microwave distribution and investigated the performance of microwave heating in the cavity.The simulation results were compared with the experimental findings us-ing the finite element analysis software of COMSOL MULTIPHYSICS to predict the temperature profile and electric field of microwave in the biomass(empty fruit bunch pellets).The higher temperature distribution was observed at the bottom and centre section of the empty fruit bunch pellet bed in the reactor,showing the uniqueness of microwave heating.According to the simula-tion results,the temperature profile obtained through the specific cavity geometry and dielectric properties agreed with the experimental temperature profile.The simulated temperature profile demonstrated a logarithmic increase of 120°C/min at the first 50 s followed by 50°C/min until 350 s.The experimental temperature profile showed three different heating rates before reaching 300°C,including 78.3°C/min(50-120°C),30.6°C/min(121-250°C),and 105°C/min(250-300°C).The results of this study might contribute to the improvement of microwave heating in biomass torrefaction. | Peter Nai Yuh Yek Sieng Huat Kong Ming Chiat Law Changlei Xia Rock Keey Liew Teck Sung Sie Jun Wei Lim Su Shiung Lam | 2022 | Journal of Bioresources and Bioproducts2022，7，4： | 0 |
| 8 | Ban fluorinated organic substances to spark green alternatives显示文摘Per-and polyfluoroalkyl substances(PFAS)do not readily biodegrade and are therefore routinely found in the environment as ubiquitous contaminants in wildlife and humans worldwide[1,2].These“forever chemicals”are among the major chemical threats to wildlife and human health nowadays and are used in consumer products,including waterproof rain wear,pizza boxes,Teflon,and firefighting foam[3,4].Due to their resistance to metabolism and excretion biomagnifying in food webs to high concentrations[5,6],PFAS can bind to proteins and affect the immune system that increase the risk of clinical and infectious diseases and autoimmunity[7–9]. | Christian Sonne Changlei Xia Su Shiung Lam | 2022 | Eco-Environment & Health2022，1，2： | 0 |
