3Multi-cycle reconfigurable THz extraordinary optical transmission using chalcogenide metamaterials显示文摘Metamaterials composed of metallic antennae arrays are used as they possess extraordinary optical transmission(EOT)in the terahertz(THz)region,whereby a giant forward light propagation can be created using constructive interference of tunneling surface plasmonic waves.However,numerous applications of THz meta-devices demand an active manipula-tion of the THz beam in free space.Although some studies have been carried out to control the EOT for the THz region,few of these are based upon electrical modulation of the EOT phenomenon,and novel strategies are required for act-ively and dynamically reconfigurable EOT meta-devices.In this work,we experimentally present that the EOT resonance can be coupled to optically reconfigurable chalcogenide metamaterials which offers a reversible all-optical control of the THz light.A modulation efficiency of 88%in transmission at 0.85 THz is experimentally observed using the EOT metama-terials,which is composed of a gold(Au)circular aperture array sitting on a non-volatile chalcogenide phase change ma-terial(Ge2Sb2Te5)film.This comes up with a robust and ultrafast reconfigurable EOT over 20 times of switching,excited by a nanosecond pulsed laser.The measured data have a good agreement with finite-element-method numerical simula-tion.This work promises THz modulators with significant on/off ratios and fast speeds.Tun Cao Meng Lian Xieyu Chen Libang Mao Kuan Liu Jingyuan Jia Ying Su Haonan Ren Shoujun Zhang Yihan Xu Jiajia Chen Zhen Tian Dongming Guo 2022Opto-Electronic Science2022,1,1:1
4Ionic liquids in transdermal drug delivery system: Current applications and future perspectives显示文摘The transdermal drug delivery(TDD) shows considerable advantages over other administration pathways.However, conventional enhancing permeation methods face a series of challenges owing to barrier function provided by the skin, of which enhancing abilities either are so strong that it results in toxicity and irritation, or too weak to achieve desirable therapeutical effects. To address these issues, it is an urgent need to develop a novel method to overcome the limitations of current measures. Fortunately, in the preceding decades, ionic liquids(ILs) have been extensively studied and increasingly applied in pharmaceutical drug delivery due to their unique physicochemical and biological properties. What is more, tunability of structure resolves the challenges in processing active pharmaceutical ingredient(API) formulation, such as polymorphism and poor solubility of drugs. Thus, the presence of ILs provides an ample design space for the transdermal drug delivery system(TDDS). This review discusses the shortcomings of conventional enhancing permeation methods and introduces the application of ILs in transdermal delivery from three aspects: i) ILs are applied as enhancers to weaken the barrier function of the stratum corneum(SC). ii) As counterions, ILs are combined with API to modify the physicochemical properties of drugs. iii) ILs assist in the design of transdermal preparation for perfecting formulation. This review comprehensively introduces the major breakthroughs made in the applications of ILs, which can serve as guidance to provide novel ideas for formulation scientists who hit the bottleneck in the development of TDD.Yang Zhang Chao Liu Jiaqi Wang Shoujun Ren Yilin Song Peng Quan Liang Fang 2023Chinese Chemical Letters2023,34,3:1
5Upconversion luminescence and optical thermometry behaviors of Yb^(3+)and Ho^(3+)co‑doped GYTO crystal显示文摘Optical thermometry based on the upconversion(UC)luminescence intensity ratio(LIR)has attracted considerable attention because of its feasibility for achievement of accurate non-contact temperature measurement.Compared with traditional UC phosphors,optical thermometry based on UC single crystals can achieve faster response and higher sensitivity due to the stability and high thermal conductivity of the single crystals.In this study,a high-quality 5 at%Yb^(3+)and 1 at%Ho^(3+)co-doped Gd_(0.74)Y_(0.2)TaO_(4)single crystal was grown by the Czochralski(Cz)method,and the structure of the as-grown crystal was characterized.Importantly,the UC luminescent properties and optical thermometry behaviors of this crystal were revealed.Under 980 nm wavelength excitation,green and red UC luminescence lines at 550 and 650 nm and corresponding to the^(5)F_(4)/^(5)S_(2)→^(5)I_(8)and^(5)F_(5)→^(5)I_(8)transitions of Ho^(3+),respectively,were observed.The green and red UC emissions involved a two-photon mechanism,as evidenced by the analysis of power-dependent UC emission spectra.The temperature-dependent UC emission spectra were measured in the temperature range of 330–660 K to assess the optical temperature sensing behavior.At 660 K,the maximum relative sensing sensitivity(S_(r))was determined to be 0.0037 K^(−1).These results highlight the signifcant potential of Yb,Ho:GYTO single crystal for optical temperature sensors.Chuancheng Zhang Shoujun Ding Miaomiao Wang Hao Ren Xubing Tang Yong Zou Renqin Dou Wenpeng Liu 2023Frontiers of Optoelectronics2023,16,3:0
6Industrial Application of an Iron-Tolerant FCC Catalyst CMT-1HN显示文摘CMT-1HN(catalyst with metal trap),the new iron-tolerant catalyst for fluidized catalytic cracking(FCC),has been successfully applied in the resid catalytic cracking unit of Sinopec Hainan Refinery and Chemical Co.,Ltd(HNRC).Two test runs were carried out to compare its performance with that of the catalyst used in the Base run.The properties of the feedstocks and operating conditions were almost similar.During the first test run,the added iron on the catalyst reached 7628μg/g,and the total iron,nickel,vanadium,and calcium contents were equivalent to those in the base run.The yield of“LPG+gasoline”increased by 0.65 percentage points,and that of dry gas decreased by 45%;the volume ratio of hydrogen to methane decreased by 9.33%.During the second test run using the upgraded CMT-1HN catalyst,the added iron on the catalyst reached 6579μg/g,and the total iron,nickel,vanadium,and calcium contents reached 23210μg/g.The yield of“LPG+gasoline”increased by 1.15 percentage points,and that of dry gas decreased by 20%;the volume ratio of hydrogen to methane decreased by 20.67%.Industrial application of the CMT-1HN catalyst proved its strong tolerance to metal contamination,especially iron poisoning,as well as its strong bottom cracking ability,leading to improved product distribution.Using CMT-1HN,the tank-bottom crude at HNRC lying in storage since several years,which is the main source of iron contamination in the equilibrium FCC catalyst(FCC E-cat),can be continuously processed to ensure smooth and cost-effective execution of the process scheme in the refinery.Liu Liqiang Liu Qianqian Chen Zhenyu Ren Fei Liu Shoujun Zhu Yuxia 2022China Petroleum Processing & Petrochemical Technology2022,24,3:0
