1用于固态照明的Mn^4+离子光谱学显示文摘Mn^4+离子激活的荧光粉在固态照明领域作为红光发射的热点载体正日益受到关注。我们针对当前研究热度撰写了Mn^4+离子光谱学的回顾,并在回顾中聚焦了许多对红色荧光粉商业研制有价值的重要基础研究点。这些研究点涵盖了如何理解自由和晶场状态下Mn^4+离子的能级结构以及Mn^4+发射波长对基质的依赖关系。此外,我们就如何实验调控Mn^4+离子掺杂型荧光粉的发射波长和发光强度给出了许多实际可行的建议。更为重要的是,我们收集并讨论了100多种荧光粉基质中Mn^4+离子光谱学参数,对它们的理解将会为未来Mn^4+掺杂型红色荧光粉的实验开发奠定基础。BRIK Mikhail G 马崇庚 SRIVASTAVA Alok M PIASECKI Michal 2020发光学报2020,41,9:11
2Adipose tissue-derived progenitor cells and cancer显示文摘Recruitment of stem cells and partially differentiated progenitor cells is a process which accompanies and facilitates the progression of cancer.One of the factors complicating the clinical course of cancer is obesity,a progressively widespread medical condition resulting from overgrowth of white adipose tissue(WAT),com-monly known as white fat.The mechanisms by which obesity in uences cancer risk and progression are not completely understood.Cells of WAT secret soluble molecules(adipokines) that could stimulate tumor growth,although there is no consensus on which cell populations and which adipokines are important.Recent reports suggest that WAT-derived mesenchymal stem(stromal) cells,termed adipose stem cells(ASC),may represent a cell population linking obesity and cancer.Studies in animal models demonstrate that adipokines secreted by ASC can promote tumor growth by assisting in formation of new blood vessels,a process necessary for expansion of tumor mass.Importantly,migration of ASC from WAT to tumors has been demonstrated,indicating that the tumor microenvironment in cancer may be modulated by ASC-derived trophic factors in a paracrine rather than in an endocrine manner.Here,we review possible positive and adverse implications of progenitor cell recruitment into the diseased sites with a particular emphasis on the role in cancer progression of progenitors that are expanded in obesity.Charles F Bellows Mikhail G Kolonin 2010World Journal of Stem Cells2010,2,5:2
3High-resolution impedance mapping using electrically activated quantitative phase imaging显示文摘Retrieving electrical impedance maps at the nanoscale rapidly via nondestructive inspection with a high signal-to-noise ratio is an unmet need,likely to impact various applications from biomedicine to energy conversion.In this study,we develop a multimodal functional imaging instrument that is characterized by the dual capability of impedance mapping and phase quantitation,high spatial resolution,and low temporal noise.To achieve this,we advance a quantitative phase imaging system,referred to as epi-magnified image spatial spectrum microscopy combined with electrical actuation,to provide complementary maps of the optical path and electrical impedance.We demonstrate our system with high-resolution maps of optical path differences and electrical impedance variations that can distinguish nanosized,semi-transparent,structured coatings involving two materials with relatively similar electrical properties.We map heterogeneous interfaces corresponding to an indium tin oxide layer exposed by holes with diameters as small as~550 nm in a titanium(dioxide)over-layer deposited on a glass support.We show that electrical modulation during the phase imaging of a macro-electrode is decisive for retrieving electrical impedance distributions with submicron spatial resolution-and beyond the limitations of electrode-based technologies(surface or scanning technologies).The findings,which are substantiated by a theoretical model that fits the experimental data very well enable achieving electro-optical maps with high spatial and temporal resolutions.The virtues and limitations of the novel optoelectrochemical method that provides grounds for a wider range of electrically modulated optical methods for measuring the electric field locally are critically discussed.Cristina Polonschii Mihaela Gheorghiu Sorin David Szilveszter Gáspár Sorin Melinte Hassaan Majeed Mikhail E.Kandel Gabriel Popescu Eugen Gheorghiu 2021Light(Science & Applications)2021,10,2:2
