| 1 | Realization of laser textured brass surface via temperature tuning for surface wettability transition显示文摘Superhydrophobic surfaces have attracted extensive interests and researches into their fundamentals and potential applications.Laser texturing provides the convenience to fabricate the hierarchical micro/nanostructures for superhydrophobicity.However,after laser texturing,long wettability transition time from superhydrophilicity to superhydrophobicity is a barrier to mass production and practical industrial applications.External stimuli have been applied to change the surface composition and/or the surface morphology to reduce wettability transition time.Herein,by temperature tuning,wettability transition of laser textured brass surfaces is investigated.Scanning electron microscopy and surface contact angle measurement are employed to characterize the surface morphology and wettability behavior of the textured brass surfaces.By low-temperature heating(100℃~150℃),partial deoxidation of the top Cu O layer occurs to form hydrophobic Cu_2O.Therefore,superhydrophobicity without any chemical coating and surface modification could be achieved in a short time.Furthermore,after low-temperature heating,the low adhesive force between the water droplet and the sample surface is demonstrated for the laser textured brass surface.This study provides a simple method to fabricate the micro/nanostructure surfaces with controllable wettability for the potential applications. | Huangping Yan Mohamed Raiz B Abdul Rashid Si Ying Khew Fengping Li Minghui Hong | 2017 | 光电工程2017，44，6： | 2 |

| 17 | 单个纳米孔的宽带光子自旋‐霍尔效应显示文摘光子自旋-霍尔效应(SHEL)指不同自旋态(圆偏振)的光子在一定条件下发生分裂的现象,在光学测量、成像、传感等领域具有重要应用前景。然而,一般条件下SHEL比较微弱,虽然通过谐振能增强分裂强度,但响应带宽受限。近期,微细加工光学技术国家重点实验室突破了上述难题,通过理论和实验证明尺度仅为2mm的单个悬链线结构即可产生宽带SHEL,相关文章近期发表于《Light:Science&Applications》。 | Huangping Yan Mohamed Raiz B Abdul Rashid Si Ying Khew Fengping Li Minghui Hong | 2017 | 光电工程2017，44，6： | 0 |
| 18 | Genomic,transcriptomic,and metabolomic analysis of Oldenlandia corymbosa reveals the biosynthesis and mode of action of anti-cancer metabolites显示文摘Plants accumulate a vast array of secondary metabolites,which constitute a natural resource for pharmaceuticals.Oldenlandia corymbosa belongs to the Rubiaceae family,and has been used in traditional medicine to treat different diseases,including cancer.However,the active metabolites of the plant,their biosynthetic pathway and mode of action in cancer are unknown.To fill these gaps,we exposed this plant to eight different stress conditions and combined different omics data capturing gene expression,metabolic profiles,and anti-cancer activity.Our results show that O.corymbosa extracts are active against breast cancer cell lines and that ursolic acid is responsible for this activity.Moreover,we assembled a high-quality genome and uncovered two genes involved in the biosynthesis of ursolic acid.Finally,we also revealed that ursolic acid causes mitotic catastrophe in cancer cells and identified three high-confidence protein binding targets by Cellular Thermal Shift Assay(CETSA)and reverse docking.Altogether,these results constitute a valuable resource to further characterize the biosynthesis of active metabolites in the Oldenlandia group,while the mode of action of ursolic acid will allow us to further develop this valuable compound. | Irene Julca Daniela Mutwil-Anderwald Vaishnervi Manoj Zahra Khan Soak Kuan Lai Lay K.Yang Ing T.Beh Jerzy Dziekan Yoon P.Lim Shen K.Lim Yee W.Low Yuen I.Lam Seth Tjia Yuguang Mu Qiao W.Tan Przemyslaw Nuc Le M.Choo Gillian Khew Loo Shining Antony Kam James P.Tam Zbynek Bozdech Maximilian Schmidt Bjoern Usadel Yoganathan Kanagasundaram Saleh Alseekh Alisdair Fernie Hoi Y.Li Marek Mutwil | 2023 | Journal of Integrative Plant Biology2023，65，6： | 0 |
| 19 | Fuzzy logic controller implementation on a microbial electrolysis cell for biohydrogen production and storage显示文摘This work presents the implementation of fuzzy logic control(FLC) on a microbial electrolysis cell(MEC).Hydrogen has been touted as a potential alternative source of energy to the depleting fossil fuels. MEC is one of the most extensively studied method of hydrogen production. The utilization of biowaste as its substrate by MEC promotes the waste to energy initiative. The hydrogen production within the MEC system, which involves microbial interaction contributes to the system's nonlinearity. Taking into account of the high complexity of MEC system, a precise process control system is required to ensure a wellcontrolled biohydrogen production flow rate and storage application inside a tank. Proportionalderivative-integral(PID) controller has been one of the pioneer control loop mechanism. However, it lacks the capability to adapt properly in the presence of disturbance. An advanced process control mechanism such as the FLC has proven to be a better solution to be implemented on a nonlinear system due to its similarity in human-natured thinking. The performance of the FLC has been evaluated based on its implementation on the MEC system through various control schemes progressively. Similar evaluations include the performance of Proportional-Integral(PI) and PID controller for comparison purposes. The tracking capability of FLC is also accessed against another advanced controller that is the model predictive controller(MPC). One of the key findings in this work is that the FLC resulted in a desirable hydrogen output via MEC over the PI and PID controller in terms of shorter settling time and lesser overshoot. | Gabriel Khew Mun Hong Mohd Azlan Hussain Ahmad Khairi Abdul Wahab | 2021 | Chinese Journal of Chemical Engineering2021，34，12： | 0 |
