The ultimate frontier in nanomaterials engineering is to realize their composition control with atomic scale precision to enable fabrication of nanoparticles with desirable size, shape and surface properties. Such control becomes even more useful when growing hybrid nanocrystals designed to integrate multiple functionalities. Here we report achieving such(More)
BACKGROUND In this study, we intended to understand the regulatory mechanisms of microRNA-125a-5p (miR-125a-5p) in human cervical carcinoma. METHODS The gene expressions of miR-125a-5p in seven cervical carcinoma cell lines and 12 human cervical carcinoma samples were evaluated by quantitative real-time reverse transcription polymerase chain reaction.(More)
We report the synthesis and characterization of cubic NaGdF4:Yb/Tm@NaGdF4:Mn core-shell structures. By taking advantage of energy transfer through Yb→Tm→Gd→Mn in these core-shell nanoparticles, we have realized upconversion emission of Mn(2+) at room temperature in lanthanide tetrafluoride based host lattices. The upconverted Mn(2+) emission, enabled by(More)
Brownian motion is one of the most fascinating phenomena in nature. Its conceptual implications have a profound impact in almost every field of science and even economics, from dissipative processes in thermodynamic systems, gene therapy in biomedical research, artificial motors and galaxy formation to the behaviour of stock prices. However, despite(More)
— Interposers that support high input/output density are becoming critical for system miniaturization and high performance. Silicon and glass are emerging as the primary candidates for such high-density interposers, due to their outstanding dimensional stability, which enables layer-to-layer wiring with small vias. However, silicon and glass have very low(More)
The synthesis of lanthanide-activated phosphors is pertinent to many emerging applications, ranging from high-resolution luminescence imaging to next-generation volumetric full-color display. In particular, the optical processes governed by the 4f-5d transitions of divalent and trivalent lanthanides have been the key to enabling precisely tuned color(More)
Due to the prevalent use of polycarbonate plastics and epoxy resins in packaging materials and paints for ships, there has been a widespread global contamination of environmental water sources with bisphenol A (BPA). BPA, an endocrine disruptor, has been found to cause tremendous health problems. Therefore, there is an urgent need for detecting BPA in a(More)
— This paper reports compliant microwire copper arrays, in thin polymer carriers, as an innovative approach for direct surface mount technology (SMT) attach of large silicon, glass, and low coefficient of thermal expansion organic interposers to printed wiring boards (PWBs). The microwire arrays (MWAs) are prefabricated as free-standing ultrathin carriers(More)
MicroRNAs have been verified to participate in various biological behaviors of different tumors, via multiple signaling pathways. Many kinds of microRNAs in hepatocellular carcinoma have been researched. However, miR-30b-5p hasn't been included. Our study aim at the impacts of miR-30b-5p on HCC and the pathway it mediating. The results showed miR-30b-5p was(More)
