Whenever the first NASA astronauts arrive on Mars, they will likely have MIT to thank for the oxygen they breathe — and for the oxygen needed to burn rocket fuel that will launch them back home to Ear...
Study on the Effect of Monochromatic Light on the Growth of the Red Tide Diatom Skeletonema Costatum
Monochromatic Light Saturated Light Intensity Skeletonema Costatum Growth Rate Red Tide
2013/1/30
Effects of light intensity and quality of three kinds of LED monochromatic lights (blue, green, and red) on the growth of Skeletonema costatum are investigated in batch culture conditions. Seven light...
A low temperature X-ray single-crystal diffraction and polarised infra-red study of epidote
epidote low-temperature X-ray single-crystal diffraction polarised single crystal FTIR structurally incorporated water hydrogen bonding.
2014/5/20
The effects of low-temperature on the crystal structure of a natural epidote [Ca1.925 Fe0.745Al2.265Ti0.004Si3.037O12(OH), a=8.8924(7), b=5.6214(3), c=10.1547(6)Å and β= 115.396(8)° at room condi...
干旱是一种频繁发生的自然灾害，遥感监测干旱已成为重要的研究方向。可从农田遥感干旱监测最主要的两种地物类型(植被和土壤)的光谱特性分析入手，选择了对水分变化敏感的红光、短波红外波段来监测干旱状况，以短波红外与红光的差值和短波红外与红光的和构建新的光谱空间特征，提出了干旱监测的新方法——归一化的干旱监测指数NPDI。用野外实测的土壤含水量对NPDI模型进行验证，结果表明：NPDI，MPDI与10 cm...

Development of High Power All-Solid-State Red, Green and Blue Lasers
All-solid-state laser High power laser Red
2009/6/1
The high power all-solid-state red, green and blue lasers have been developed by means of Q-switched diode side-pumped Nd:YAG laser modules and the intracavity nonlinear frequency conversion in the LB...
Optical properties of deposit of red blood cells suspended in dextran solutions
light scattering RBC sedimentation dextran
2011/5/6
The optical properties of the deposit of red blood cells (RBCs) formed during sedimentation have
been investigated. The human blood was obtained from healthy donors. RBCs were suspended in

Red up-conversion dynamics in Er3+-doped TeO2–ZnO glasses
tellurite glasses erbium: Er3+ dynamics of up-conversion
2011/5/6
Red fluorescence has been obtained under 980 nm excitation in Er3+-doped TeO2–ZnO glasses.
The dynamics of the red up-conversion is well explained with the proposed model. The energy
transfer proces...
Red-emitting LiEuW2O8 phosphor for white emitting diodes prepared by sol–gel process
phosphors sol–gel near-UV
2011/5/10
Scheelite-type LiEuW2O8 (LEW) phosphors with the optical function of color conversion from near-UV to red were prepared by sol–gel method using a lithium acetate dehydrate, europium(III) nitrate pent...
All-optical Vestigial-Sideband Signal Generation and Pattern Effect Miti- gation with an SOA Based Red-Shift Optical Filter Wavelength Converter
All-optical Vestigial-Sideband Signal SOA Based Red-Shift Optical Wavelength Converter
2015/8/3
We demonstrate 40 Gb/s SOA-based wavelength conversion from a RZ into a vestigial-sideband RZ signal. SOA related pattern effects are successfully suppressed by proper choice of the red-shift optical ...
