Higher order multiphoton-pumped polarized lasers have fundamental technological importance. Although they can be used to in vivo imaging, their application has yet to be realized. Here we show the first polarized three-photon-pumped (3PP) microcavity laser in a single host-guest composite metal-organic framework (MOF) crystal, via a controllable in situ self-assembly strategy. The highly orient...

The industrially-important WC-Co composite materials provide a useful, albeit complicated materials system for understanding the combined influences on hardness and strength properties of the constituent WC particle strengths, the particle sizes, their contiguities, and of Co binder hardness and mean free paths, and in total, the volume fraction of constituents. A connection is made here betwee...

We present a simple, cost-effective, robust, and scalable approach for fabricating a nanogenerator that gives an output power strong enough to continuously drive a commercial liquid crystal display. Utilizing the conical shape of the as-grown ZnO nanowires, a nanogenerator is fabricated by simply dispersing them onto a flat polymer film to form a rational "composite" structure. It is suggested ...

A method of measuring gamma-ray relative intensities was developed which used a germanium .bent-crystal spectrometer as a monochromator. The response function of a Nai detector to the essentially monoenergetic gamma rays, obtained from the diffracted beam of the spectrometer, was recorded in a multichannel analyzer. The composite spectrum due to all the gamma rays was then recorded in the analy...

Graphene-decorated V2O5 nanobelts (GVNBs) were synthesized via a low-temperature hydrothermal method in a single step. V2O5 nanobelts (VNBs) were formed in the presence of graphene oxide, a mild oxidant, which also enhanced the conductivity of GVNBs. From the electron energy loss spectroscopy analysis, the reduced graphene oxide (rGO) are inserted into the layered crystal structure of V2O5 nano...

materials with high electrical and thermal conductivity, respectively with microstructural stability and high temperature strength, are very attractive for the electricelectronic industry and special machine building industry (actively-cooled parts, rocket nozzles, magnet wire and cables, welding electrode tips). copper is one of the most promising metals for these applications because it has t...

In this work, copper micropillars and copper-carbon nanotube (CNT) composite micropillars were fabricated by incorporating an electrodeposition technique with a xurography process. In order to disperse carbon nanotubes in copper-CNT micropillars, various amounts of CNTs were added to the electroplating bath. Surface morphology and phase characterization of copper micropillars and copper-CNT com...

We describe a distinct type of spontaneous hierarchical self-assembly of cytoskeletal filamentous actin (F-actin), a highly charged polyelectrolyte, and cationic lipid membranes. On the mesoscopic length scale, confocal microscopy reveals ribbonlike tubule structures that connect to form a network of tubules on the macroscopic scale (more than 100 micrometers). Within the tubules, on the 0.5- t...

The effect of submicron-sized Al2O3 particle addition on the crystal structure and superconducting properties of YBa2Cu3O7-δ ceramics was systematically studied. Series of YBa2Cu3O7−δ + x Al2O3 samples (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5,0.6 wt.% ) were prepared using the solid state reaction method. The lattice parameters and the orthorhombicity were decreased slightly with Al2O3 addition. No ch...

The length scales defining structure and organization determine the fundamental characteristics of a material. Traditional ceramic materials exhibit organization on two length scales: the atomic scale, e.g., the unit cell of the crystal or the local arrangement of amorphous materials, and the scale of the grain size within the composite, typically much longer length and on the order of micromet...
