1采用柠檬酸合成高分散铜催化剂用于选择氢解反应(英文)显示文摘A highly dispersed Cu catalyst supported on silica was prepared by an incipient wetness impregnation method with citric acid.The synthesis was studied by nitrogen physisorption,X-ray diffraction,and temperature-programmed reduction by comparing with a reference prepared without citric acid.The catalyst precursor obtained after impregnation was X-ray amorphous.The precursor was readily transformed to crystalline CuO upon calcination.The CuO particles were of uniform size in a highly dispersed state and can be reduced to Cu at a lower temperature.The activity of the Cu catalyst obtained was an order of magnitude higher than that of the reference for the hydrogenolysis of methyl laurate to dodecanol.Ming-Hoong LOOI Shuk-Tong LEE Sharifah Bee ABD-HAMID 2008催化学报2008,29,6:8
2Electrochemical Generation of Cubic Shaped Nano Zn_2SnO_4 Photocatalysts显示文摘In this contribution, an efficient and simple two-step hybrid electrochemical-thermal route was developed for the synthesis of cubic shaped Zn_2SnO_4 (ZTO) nanoparticles using aqueous sodium bicarbonate(NaHCO_3) and sodium stannate(Na_2SnO_3) electrolyte. The sacrificial Zn was used as anode and cathode in an undivided cell under galvanostatic mode at room temperature. The bath concentration and current density were respectively varied from 30 to 120 mmol and 0.05 to 1.5 A/dm^2. The electrochemically generated precursor was calcined for an hour at different range of temperature from 60 to 600. The crystallite sizes in the range of 24-53 nm were calculated based on Debye-Scherrer equation. Scanning electron microscope and transmission electron microscopy results reveal that all the particles have cubic morphology with diameter of40-50 nm. The as-prepared ZTO samples showed higher catalytic activity towards the degradation of methylene blue(MB) dye, and 90% degradation was found for the sample calcined at 600, which is greater than that of commercial TiO_2-P25 photocatalysts. The photodegradation efficiency of ZTO samples was found to be a function of exposure time and the dye solution p H value. These results indicate that the ZTO nanoparticles may be employed to remove dyes from wastewater.Chandrappa K.Govindappa Venkatesha T.Venkatarangaiah Sharifah B.Abd Hamid 2013Nano-Micro Letters2013,5,2:5
3Determination of calorie and protein intake among acute and sub-acute traumatic brain injury patients显示文摘Purpose:Malnutrition is a common problem among hospitalized patients,especially among traumatic brain injury(TBI)patients.It is developed from hypermetabolism and the condition may worsen under the circumstance of underfeeding or incompatible dietary management.However,the data of nutrient intake especially calorie and protein among TBI patients were scarce.Hence,this study aimed to determine the calorie and protein intake among acute and sub-acute TBI patients receiving medical nutrition therapy in hospital Sultanah Nur Zahirah,Terengganu.Methods:This observational study involved 50 patients recruited from the neurosurgical ward.Method of 24 h dietary recall was utilized and combined with self-administered food diaries for 2-8 days.Food consumptions including calorie intake and protein intake were analyzed using Nutritionist PRO™(Woodinville,USA)and manual calculation based on the Malaysian food composition database(2015).Results:Patients consisted of 56%males and 44%females with the median age of 28.0(IQR=22.8-36.5)years,of which 92%were diagnosed as mild TBI and the remaining(8%)as moderate TBI.The Glasgow coma scale(GCS)was adopted to classify TBI severity with the score 13-15 being mild and 9-12 being moderate.The median length of hospital stay was 2(IQR=2.0e3.3)days.Calorie and protein intake improved significantly from day 1 to discharge day.However,the intake during discharge day was still considered as suboptimal,i.e.75%of calorie requirement,whilst the median protein intake was only 61.3%relative to protein requirement.Moreover,the average percentages of calorie and protein intakes throughout hospitalization were remarkably lower,i.e.52.2%and 41.0%,respectively.Conclusion:Although the calorie and protein intakes had increased from baseline,hospitalized TBI patients were still at a risk to develop malnutrition as the average intakes were considerably low as compared to their requirements.Optimum nutrient intakes especially calorie and protein are crucial to ensure optimum recovery process as well as to minimize risks of infection and complications.Mohd Ibrahim Abdullah Aryati Ahmad Sharifah Wajihah Wafa Syed Saadun Tarek Wafa Ahmad Zubaidi Abdul Latif Noor Aini Mohd Yusoff Muhammad Khalis Jasmiad Nujaimin Udin Kartini Abdul Karim 2020Chinese Journal of Traumatology2020,23,5:3
4高活性多壁碳纳米管/TiO_2纳米复合物光催化剂光催化降解活性黑5染料(英文)显示文摘A nanocomposite UV-visible light-responsive multiwalled carbon nanotube (MWCNT)/titanium dioxide(TiO2) nanophotocatalyst was successfully synthesized by a modified sol-gel method using titanium isopropoxide and functionalized MWCNTs as the starting precursors. The photocatalytic activity of the TiO2 and the nanohybrid material was investigated through the photodegradation of Reactive Black 5 dye under ultraviolet light irradiation. X-ray diffraction analysis indicated that anatase phase was obtained for both the pure TiO2 and the MWCNT/TiO2 composite, while Raman spectroscopy confirmed the presence of MWCNTs in the composite. Field emission scanning elec-tron microscopy revealed that TiO2 nanoparticles with an individual diameter of about 10–20 nm were coated on the surface of the MWCNTs. The specific surface areas of the samples were found to be 80 and 181 m2/g for the pure TiO2 and MWCNT/TiO2, respectively. As a result, MWCNT/TiO2 showed better photocatalytic performance than pure TiO2 because the high surface area of MWCNTs enabled them to function as good electron acceptors for the retardation of electron-hole pair recombination.Sharifah Bee Abd Hamid Tong LingTan Chin WeiLai Emy Marlina Samsudin 2014催化学报2014,35,12:3

6Land use change in highland area and its impact on river water quality:a review of case studies in Malaysia显示文摘The policy of encouraging agriculture and development for mass tourism has led to environmental problems in Cameron Highlands,Malaysia.Rampant development and land clearing have significantly altered the land cover of Cameron Highlands for the past 30 years.Sensitive highlands areas are prone to landslides and soil erosion which then contributed to the main water pollution issues in the network of river system,sedimentation and siltation.The continuous trend of river water quality deterioration in Cameron Highlands has raised the issues for discussion in this review article.The purpose of this review is to briefly summarize the land use change,agriculture practices,agro-tourism,and agriculture policy and management toward water quality of the river system network in Cameron Highlands specifically in the downtown where most of the development and agriculture activities are concentrated.A rigorous review has been done on the existing literature to determine the relationship between land use change and agriculture practices toward river water quality in Cameron Highlands from 2001 to 2017.The total number of reviewed papers was 68.The outcomes established from previous researchers have highlighted factors such as soil erosion,landslides,agriculture activities,urbanization,and unplanned development associated with land use change have significantly influenced the river water quality in the highland areas.Continuous land use changes without proper development plan and law enforcement may critically threaten the sustainability of river network in the highlands area.Azlini Razali Sharifah Norkhadijah Syed Ismail Suriyani Awang Sarva Mangala Praveena Emilia Zainal Abidin 2018Ecological Processes2018,7,1:2
7The influence of Ca and Cu additions on the microstructure,mechanical and degradation properties of Zn-Ca-Cu alloys for absorbable wound closure device applications显示文摘Novel ternary Zn-Ca-Cu alloys were studied for the development of absorbable wound closure device material due to Ca and Cu’s therapeutic values to wound healing.The influence of Ca and Cu on the microstructure,mechanical and degradation properties of Zn were investigated in the as-cast state to establish the fundamental understanding on the Zn-Ca-Cu alloy system.The microstructure of Zn-0.5Ca-0.5Cu,Zn-1.0Ca-0.5Cu,and Zn0.5Ca-1.0Cu is composed of intermetallic phase CaZn13 distributed within the Zn-Cu solid solution.The presence of CaZn13 phase and Cu as solute within the Zn matrix,on the one hand,exhibited a synergistic effect on the grain refinement of Zn,reducing the grain size of pure Zn by 96%;on the other hand,improved the mechanical properties of the ternary alloys through solid solution strengthening,second phase strengthening,and grain refinement.The degradation properties of Zn-Ca-Cu alloys are primarily influenced by the micro-galvanic corrosion between Zn-Cu matrix and CaZn13 phase,where the 0.5%and 1.0%Ca addition increased the corrosion rate of Zn from 11.5μm/y to 19.8μm/y and 29.6μm/y during 4 weeks immersion test.Nan Yang Nagasivamuni Balasubramani Jeffrey Venezuela Sharifah Almathami Cuie Wen Matthew Dargusch 2021Bioactive Materials2021,6,5:2
