| 1 | Rapid growth and properties of large-aperture 98%-deuterated DKDP crystals显示文摘In this paper,a highly deuterated potassium dihydrogen phosphate(DKDP)crystal with sizes up to 318 mm×312 mm×265 mm was grown by the rapid-growth method.The synthesis tank device was specially designed to synthesize a higher deuterium concentration and high-purity DKDP solution.The deuterium content of the as-grown crystal,which was 97.9%,was determined by two methods,including infrared(IR)spectroscopy and thermo-gravimetric analysis(TGA)measurements.The performances of the 97.9%DKDP crystal,including transmission,absorption coefficient,and laserinduced damage threshold(LIDT)were measured.The results indicate that,in the near-infrared band,the transmission of the 97.9%DKDP crystal is higher than that of KDP and 70%DKDP crystals,and the absorption coefficient is lower.The LIDT of the crystal reached 23.2 J·cm^-2(R-on-1,1064 nm,3 ns),which meets the engineering requirements for use in optical applications. | Xumin Cai Xiuqing Lin Guohui Li Junye Lu Ziyu Hu Guozong Zheng | 2019 | High Power Laser Science and Engineering2019，7，3： | 4 |
| 2 | Rapid growth of a large-scale(600 mm aperture) KDP crystal and its optical quality显示文摘Potassium dihydrogen phosphate(KDP) single crystals are the only nonlinear crystals currently used for electro-optic switches and frequency converters in inertial confinement fusion research, due to their large dimension and exclusive physical properties. Based on the traditional solution-growth process, large bulk KDP crystals, usually with sizes up to600 × 600 mm2 so as to make a frequency doubler for the facility requirement loading highly flux of power laser, can be grown in standard Holden-type crystallizers, without spontaneous nucleation and visible defects, one to two orders of magnitude faster than by conventional methods. Pure water and KDP raw material with a few ion impurities such as Fe,Cr, and Al(less than 0.1 ppm) were used. The rapid-growth method includes extreme conditions such as temperature range from 60 to 35℃ , overcooling up to 5℃ , growth rates exceeding 10 mm/day, and crystal size up to 600 mm. The optical parameters of KDP crystals were determined. The optical properties of crystals determined indicate that they are of favorable quality for application in the facility. | Guohui Li Guozong Zheng Yingkun Qi Peixiu Yin En Tang Fei Li Jing Xu Taiming Lei Xiuqin Lin Min Zhang Junye Lu Jinbo Ma Youping He Yuangen Yao | 2014 | High Power Laser Science and Engineering2014，2，1： | 3 |
| 3 | From the Himalayan region or the Malay Archipelago:Molecular dating to trace the origin of a fern genus Phymatopteris(Polypodiaceae)显示文摘Phymatopteris Pic.Serm.,a derived polypodiaceous fern,is one of the many fern genera that still suffer from nomenclatural confusion.Its generic circumscription and phylogenetic relationships with other selligueoid ferns have been controversial,and its geographic origin,whether in the Himalayan region of continental Asia or in Malay Archipelago,is still unknown.A phylogeny of all selligueoid ferns based on 4 cpDNA(rbcL,trnL-F,rps4 and rps4-trnS) regions indicates that Phymatopteris is not monophyletic.Phymatopteris species are distributed in 5 well-supported clades that can be distinguished with frond-shape and frond-margin characters.All early-divergent species are from the Malaysian Archipelago,while the remaining species are all from the Himalayan region and form a recently diverged group that is largely unresolved,most likely having resulted from an explosive radiation.Divergence-time estimation suggests that the first diversification of selligueoid ferns occurred at ca.27 Ma in the Malaysian Archipelago,followed by migration into the Himalayan region around 20 Ma.The radiation of the Himalayan species occurred mostly within the last 20 million years,within the period of recent major uplifts of the Qinghai-Tibetan Plateau(between the early Miocene and the Pleistocene) and late-Cenozoic global cooling.Our evidence leads us to propose that the Malaysian Archipelago is the ancestral area for Phymatopteris. | LI ChunXiang LU ShuGang MA JunYe SUN XiaoYan GAI YongHua BARRINGTON David S YANG Qun | 2012 | Chinese Science Bulletin2012，57，35： | 1 |
| 4 | Robust hydrogel sensors for unsupervised learning enabled sign-to-verbal translation显示文摘Highly stretchable and robust strain sensors are rapidly emerging as promising candidates for a diverse of wearable electronics.The main challenge for the practical application of wearable electronics is the energy consumption and device aging.Energy consumption mainly depends on the conductivity of the sensor,and it is a key factor in determining device aging.Here,we design a liq-uid metal(LM)-embedded hydrogel as a sensing material to overcome the bar-rier of energy consumption and device aging of wearable electronics.The sensing material simultaneously exhibits high conductivity(up to 22 S m�1),low elastic modulus(23 kPa),and ultrahigh stretchability(1500%)with excel-lent robustness(consistent performance against 12000 mechanical cycling).A motion monitoring system is composed of intrinsically soft LM-embedded hydrogel as sensing material,a microcontroller,signal-processing circuits,Bluetooth transceiver,and self-organizing map developed software for the visu-alization of multi-dimensional data.This system integrating multiple functions including signal conditioning,processing,and wireless transmission achieves monitor hand gesture as well as sign-to-verbal translation.This approach provides an ideal strategy for deaf-mute communicating with normal people and broadens the application of wearable electronics. | Hude Ma Haiyang Qin Xiao Xiao Na Liu Shaolei Wang Junye Li Sophia Shen Shuqi Dai Mengmeng Sun Peiyi Li Xiaofang Pan Mingjun Huang Baoyang Lu Jun Chen Lidong Wu | 2023 | InfoMat2023，5，7： | 1 |
| 5 | Dual inhibition of glycolysis and oxidative phosphorylation by aptamer-based artificial enzyme for synergistic cancer therapy显示文摘Dual inhibition of glycolysis and oxidative phosphorylation(OXPHOS)can break the metabolic plasticity of cancer cells to inhibit most energy supply and lead to effective cancer therapy.However,the pharmacokinetic difference among drugs hinders these two inhibitions to realize a uniform temporal and spatial distribution.Herein,we report an aptamer-based artificial enzyme for simultaneous dual inhibition of glycolysis and OXPHOS,which is constructed by arginine aptamer modified carbon-dots-doped graphitic carbon nitride(AptCCN).AptCCN can circularly capture intracellular arginine attribute to the specific binding ability of arginine aptamers to arginine,and further catalyze the oxidation of enriched arginine to nitric oxide(NO)under red light irradiation.In vitro and in vivo experiments showed that arginine depletion and NO stress could inhibit glycolysis and OXPHOS,leading to energy blockage and apoptosis of cancer cells.The presented aptamer-based artificial enzyme strategy provides a new path for cell pathway regulation and synergistic cancer therapy. | Xiao Fang Meng Yuan Junduan Dai Qianying Lin Yuhong Lin Wenli Wang Yifan Jiang Haihui Wang Fang Zhao Junye Wu Shumeng Bai Chunhua Lu Huanghao Yang | 2022 | Nano Research2022，15，7： | 0 |
