A combination of surfaceand bulk-micromachining techniques is used to demonstrate the feasibility of fabricating microhypodermic needles. These microneedles, which may be built with on-board fluid pumps, have potential applications in the chemical and biomedical fields for localized chemical analysis, programmable drug-delivery systems, and very small, precise sampling of fluids. The microneedl...

The search for semiconductors that can be solutionprocessed into thin-film form at low temperature, while simultaneously providing quality device characteristics, represents a significant challenge for materials chemists. Continuous thin films with field-effect mobilities of 10 cm V s or greater are particularly desirable for high-speed microelectronic applications. Attainment of this goal shou...

This report represents the completion of a three-year Laboratory-Directed Research and Development (LDRD) program to develop a low cost platform for integrated microsystems that is easily configured to meet a wide variety of specific applications-driven needs. Once developed, this platform, which incorporates many of the elements that are common to numerous microsystems, will enable integrated ...

Parallel Tubular Channel Angular Pressing (PTCAP) process is a novel recently developed severe plastic deformation (SPD) method for producing ultrafine grained (UFG) and nanograined (NG) tubular specimens with excellent mechanical and physical properties. This process has several advantageous compared to its TCAP counterparts. In this paper, a fine grained AZ91 tube was fabricated via multi pas...

Background: Capparis spinosa is used in different countries for prevention and treatment of various diseases. Its fruits are usually used in processed form especially with vinegar. Objective: The aim of the present study was investigating the effect of processing on some phytochemical constituents and biological activities of C. spinosa. Methods: The fruits were processed with grape vinegar. To...

background: these findings from several observational studies, investigated the association between red meat consumption and gliomas, were inconsistent. we conducted a systematic review and meta-analysis of observational studies to summarize available date on the relation between meat intake and risk of glioma. materials and methods: a systematic literature search of relevant reports published ...
