It is well-established that wool and glass fibers are good absorbers for noise-control in air. However, inadequate levels of stiffness and strength have limited the range of the use of such fibers. The emergence of fibrous metal foams has meant rethinking of these limitations. Fibrous metal foams can be filled, not just with air, but also with other types of fluids. This means that altering bot...

Most polymeric tribological components are inherently insulative, resulting in susceptibility to failure from frictional heating at the PV limit, which is typically reported as a product of the heat flux terms pressure (P) and sliding speed (V). This letter reports on the design of a tribological composite for increased thermal conductivity and PV limit. The control sample is an unfilled compos...

Methods for predicting organic solvents, chromic acid, mineral oil, styrene, and sulphuric acid emissions in painting, metal degreasing, wood preservation, chromium electroplating, turning, grinding, making glass fortified polyester laminates and lead batteries charging, injection moulding of polystyrene plastics, and making polyurethane foam processes are described. Experimentally introduced e...

We present the state of development of the practical low-loss and low-dispersion terahertz fibers. We investigate the optical characteristics of two-wire plasmonic waveguides, porous, and foam-based dielectric waveguides and highlight their advantages and disadvantages. Our research group demonstrated a hybrid metal-dielectric fiber resulting from fusion of the two aforementioned types of waveg...

Electrochemical performance and production cost are the main concerns for the practical application of supercapacitors. Here we report a simple and universally applicable method to prepare hybrid metal oxides by metal redox reaction utilizing the inherent reducibility of metals and oxidbility of for the first time. As an example, Ni(OH)2/MnO2 hybrid nanosheets (NMNSs) are grown for supercapacit...

To date, high compressive ductility and energy absorption have been achieved in amorphous metal foams based on high-toughness Pdand Zr-based metallic glasses and are known to result from two extrinsic toughening mechanisms: bending of struts and shear band arrest by pores. We study here a syntactic amorphous metallic foam produced by infiltration of a bed of hollow crystalline iron spheres with...

Two user studies evaluated gameplay on a touchscreen phone. A “run and gun” study compared a nanostick, foam buttons, a soft gamepad, and a Wii Remote. User performance was measured using Metal Slug on an Android phone. The Wii Remote performed best (fewer player deaths, lower completion times), the soft gamepad worst. The nano-stick was second best, but was rated on a par with the Wiimote by p...

Application of foam in EOR, increases macroscopic sweep efficiency via awesome increscent of mobility control. Macroscopic manifestation of foam application performance in porous media is complex process that involves several interacting microscopic foam events. Stability as an important factor in foam injection within large reservoirs, depends on several variables including oil saturation, con...

There is growing interest in thin, lightweight, and flexible energy storage devices to meet the special needs for next-generation, high-performance, flexible electronics. Here we report a thin, lightweight, and flexible lithium ion battery made from graphene foam, a three-dimensional, flexible, and conductive interconnected network, as a current collector, loaded with Li(4)Ti(5)O(12) and LiFePO...

A new geometric modeling of isotropic highly-porous cellular media, e.g., open-cell metal, ceramic, and graphite foams, is developed. The modelling valid strictly for macroscopically two-dimensional heat transfer due to the fluid flow in media. Unlike current geometrical such model employs simple geometry, derived from equivalency conditions that are imposed on model’s geometry a priori, order ...
