Strategic Study of CAE 2020, Volume 22, Issue 3,   Pages 92-99 doi: 10.15302/J-SSCAE-2020.03.014

Abstract:

Space laser communication technology is a major communication technology for space broadband information transmission in the future and has the advantages of high bandwidth, fast and convenient transmission, and low cost. It is the best means to cover the“last kilometer” of information transmission. This study aims to systematically understand the development process of the space laser communication technology. It summarizes the development of research and experimental verification of the technology in China and abroad regarding satellite-ground, inter-satellite, space-ground, and inter-space links. The key technologies of laser communication are studied in detail regarding acquisition tracking, communication transceiving, atmospheric compensation, and optomechanical design. Based on this, five future development trends of space laser communication are summarized emphatically, that is, high speed, networking, multi-purpose, integration, and multi-band. To further promote the research and industrialization of the space laser communication technology, this study proposes implementing basic research plans, focusing on the research and development of core components, actively participating in the formulation of international technical standards, and guiding the development of related industries.

Talin and kindlin: the one-two punch in integrin activation

Feng Ye, Adam K. Snider, Mark H. Ginsberg

Frontiers of Medicine 2014, Volume 8, Issue 1,   Pages 6-16 doi: 10.1007/s11684-014-0317-3

Abstract:

Proper cell-cell and cell-matrix contacts mediated by integrin adhesion receptors are important for development, immune response, hemostasis and wound healing. Integrins pass trans-membrane signals bidirectionally through their regulated affinities for extracellular ligands and intracellular signaling molecules. Such bidirectional signaling by integrins is enabled by the conformational changes that are often linked among extracellular, transmembrane and cytoplasmic domains. Here, we review how talin-integrin and kindlin-integrin interactions, in cooperation with talin-lipid and kindlin-lipid interactions, regulate integrin affinities and how the progress in these areas helps us understand integrin-related diseases.

concentration of carboxymethyl cellulose on morphology of hydroxyapatite nanoparticles as prepared with one-step

Ruiqiang LIU,Rattan LAL

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 804-812 doi: 10.1007/s11783-015-0785-y

Abstract: Nano-sized apatite particles (nAP) synthesized with carboxymethyl cellulose (CMC) have shown great application potentials in in situ heavy metal remediation. However, differences in CMC’s properties effects on the size of nAP produced are not well understood. In this paper, two types of CMC, with respective molecular weights (MW) of ~120000 and ~240000 Dalton or respective polymerization degrees of 500 (CMC-500) and 1050 (CMC-1050), were studied in a concentration range of 0.05%–0.5% (w/w) for nAP synthesis. Morphology of the particles was characterized with transmission electron microscopy (TEM). Results showed that 0.05% CMC-500 solution gave an average particle size of 148.7±134.9 nm, 0.25% CMC-500 solution produced particles of 21.8±20.4 nm, and, 0.5% CMC-500 solution contained particles of 15.8±7.7 nm. In comparison, 0.05% CMC-1050 solution produced nanoparticles of 6.8±3.2 nm, 0.25% CMC-1050 produced smaller nAP of 4.3±3.2 nm, and 0.5% CMC-1050 synthesized the smallest nanoparticles in this study, with an average diameter of 3.0±2.1 nm. Chemical composition of the products was identified with X-ray diffraction (XRD) as pure hydroxyapatite. Interactions between nAP and CMC were discussed with help of attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopic data. This study showed that CMC at higher concentration as well as higher MW facilitated to produce finer nanoparticles, showing that nAP size could be manipulated by selecting appropriate CMC MW and/or applying appropriate CMC concentration.

Hierarchical porous carbon derived from one-step self-activation of zinc gluconate for symmetric supercapacitors

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 4,   Pages 387-394 doi: 10.1007/s11705-022-2250-3

Abstract: Porous carbons with high specific area surfaces are promising electrode materials for supercapacitors. However, their production usually involves complex, time-consuming, and corrosive processes. Hence, a straightforward and effective strategy is presented for producing highly porous carbons via a self-activation procedure utilizing zinc gluconate as the precursor. The volatile nature of zinc at high temperatures gives the carbons a large specific surface area and an abundance of mesopores, which avoids the use of additional activators and templates. Consequently, the obtained porous carbon electrode delivers a satisfactory specific capacitance and outstanding cycling durability of 90.9% after 50000 cycles at 10 A∙g–1. The symmetric supercapacitors assembled by the optimal electrodes exhibit an acceptable rate capability and a distinguished cycling stability in both aqueous and ionic liquid electrolytes. Accordingly, capacitance retention rates of 77.8% and 85.7% are achieved after 50000 cycles in aqueous alkaline electrolyte and 10000 cycles in ionic liquid electrolyte. Moreover, the symmetric supercapacitors deliver high energy/power densities of 49.8 W∙h∙kg–1/2477.8 W∙kg–1 in the Et4NBF4 electrolyte, outperforming the majority of previously reported porous carbon-based symmetric supercapacitors in ionic liquid electrolytes.
