Fluorescence imaging (FI) in the second near-infrared (NIR-II) window has emerged as a promising method for cancer diagnosis because of its superior properties such deep penetration depth and high signal-to-background ratio. Despite superiorities organic conjugated nanomaterials NIR-II FI, issues low fluorescence quantum yield, weak metabolic capability, undefined molecular structure polymers, ...


 In Southeastern Kentucky a small, cold stream-dwelling crayfish, Cambarus jezerinaci, located in the and Cumberland River basin may be part of species complex. A previous study done 2008 on cytochrome oxidase 1 gene (CO1) C. jezerinaci parvoculus, sister region, identified third genetically distinct lineage most similar to currently retained as Group B jezerinaci. is different from true ...

Abstract The European ( Melolontha melolontha L.) and Forest M. hippocastani F.) cockchafer are widespread pests throughout Central Europe. Both species exhibit a 3–5-year life cycle occur in temporally shifted populations, which have been monitored documented for more than 100 years. Visual identification of adults larvae belonging to these morphologically similar requires expertise and, parti...

A series of Co1 xCux (x 1⁄4 0:05{0:70) composite nanowire arrays have been electrodeposited in alumina templates. An apparent pH value rule for nanowire phase and composition has been found. Based on it, composite nanowires can be obtained and the composition becomes more controllable. In the composite nanowires, the cubic and hexagonal structures coexisted. The specific magnetic properties, co...
