| 1 | In vitro anti-hyaluronidase activity of Sri Lankan low grown orthodox orange pekoe grade black tea(Camellia sinensis L.)显示文摘Objective:To access the anti-hyaluronidase activity of Sri Lankan low grown orthodox orange pekoe(OP) grade black tea with a view to develop an anti-aging skin formulation.Methods:Five concentrations(0.125,0.250,0.500,1.000 and 2.000 mg/mL) of black tea brew(BTB) were made using a freeze dried sample of Sri Lankan low grown orthodox OP grade black tea which was prepared according to international organization for standardization specification.Epigallocatechin gallate(EGCG) was used as the reference agent(concentrations tested:0.012,0.025,0.050,0.100 and 0.200 mg/mL).Anti-hyaluronidase activity of BTB and EGCG in vitro were ascertained spectrometrically using hyaluronic acid(from rooster comb)and bovine testicular hyaluronidase.Results:The results revealed that BTB had moderate[IC_(50)=(1.09±0.12) mg/mL]and dose dependent(r^2=0.94) anti-hyaluronidase activity.EGCG also exhibited dose dependent(r^2=0.93,P<0.05) anti-hyaluronidase activity which was superior[IC_(50)=(0.09±0.00) mg/mL]to BTB.Conclusions:Sri Lankan low grown orthodox OP gradc black tca has promising antihyaluronidase activity in vitro and has the potential to be used as an anti-aging cosmaceutical.In addition,it may prove useful as a beverage in the management of allergy,some joint diseases and cnvenomation. | Wanigasekera Daya Ratnasooriya Walimuni Prabhashini Kaushalya Mendis Abeysekera Chatura Tissa Dayendra Ratnasooriya | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，12： | 2 |

| 8 | Modelling charge transport and electro-optical characteristics of quantum dot light-emitting diodes显示文摘Quantum dot light-emitting diodes(QD-LEDs)are considered as competitive candidate for next-generation displays or lightings.Recent advances in the synthesis of core/shell quantum dots(QDs)and tailoring procedures for achieving their high quantum yield have facilitated the emergence of high-performance QD-LEDs.Meanwhile,the charge-carrier dynamics in QD-LED devices,which constitutes the remaining core research area for further improvement of QD-LEDs,is,however,poorly understood yet.Here,we propose a charge transport model in which the charge-carrier dynamics in QD-LEDs are comprehensively described by computer simulations.The charge-carrier injection is modelled by the carrier-capturing process,while the effect of electric fields at their interfaces is considered.The simulated electro-optical characteristics of QD-LEDs,such as the luminance,current density and external quantum efficiency(EQE)curves with varying voltages,show excellent agreement with experiments.Therefore,our computational method proposed here provides a useful means for designing and optimising high-performance QD-LED devices. | Sung-Min Jung Tae Hoon Lee Sang Yun Bang Soo Deok Han Dong-Wook Shin Sanghyo Lee Hyung Woo Choi Yo-Han Suh Xiang-Bing Fan Jeong-Wan Jo Shijie Zhan Jiajie Yang Chatura Samarakoon Yoonwoo Kim Luigi GOcchipinti Gehan Amaratunga Jong Min Kim | 2021 | npj Computational Materials2021，，1： | 0 |
