In search a hydrogen source, we synthesized TiO2-Cu-graphene composite photocatalyst for evolution. The catalyst is new and unique material as it consists of copper-decorated TiO2 particles covered tightly in graphene obtained fluidized bed reactor. Both, reduction copper from Cu(CH3COO) at the surface covering TiO2-Cu thin layer by Chemical Vapour Deposition (CVD) were performed subsequently f...
We present a new technique allowing us to build freely suspended two-dimensional electron gases from AlGaAs/GaAs/AlAs heterostructures. This technique relies on an MBE-grown structures that includes a sacrificial layer. ( 1998 Elsevier Science B.V. All rights reserved.
Radical-induced addition-fragmentation processes were efficiently used for surface modification of fumed silica, and Z-supported solid CTAs could be reused in presence of excess sacrificial thermal initiator.
Multidimensional polypyrrole nanotubes (MPPy NTs) were successfully fabricated as chemiresistors on a sacrificial nanofiber template by vapor deposition polymerization (VDP) and used to discriminate volatile organic compounds (VOCs) and toxic gases.
A new approach to preparing porous carbons with desirable pore structure and morphology is demonstrated by using an appropriate pair of polycarboxylic acid/anhydride and diamine in the presence of a metal salt without a sacrificial template.
Pt and Pd nanotubes could be prepared rapidly with high yields and good uniformity through the reduction of metal precursors in the presence of ZnO nanowires as inexpensive sacrificial templates. The prepared nanotubes showed efficient electrocatalytic properties toward alcohol oxidation.
This manuscript describes the use of water-soluble polymers for use as sacrificial layers in surface micromachining. Water-soluble polymers have two attractive characteristics for this application: 1) They can be deposited conveniently by spin-coating, and the solvent removed at a low temperature (95-150 degrees C), and 2) the resulting layer can be dissolved in water; no corrosive reagents or ...
Often in romantic relationships, conflict arises which may be resolved when one partner gives up their own self-interests for the well-being of their partner or relationship. Past research has focused on sacrifice through self-reported measures of hypothetical behavior and measures involving both partners in the relationship. The current study sought to create an inexpensive behavioral measure ...
Wafer-scale fabrication of complex nanofluidic systems with integrated electronics is essential to realizing ubiquitous, compact, reliable, high-sensitivity and low-cost biomolecular sensors. Here we report a scalable fabrication strategy capable of producing nanofluidic chips with complex designs and down to single-digit nanometre dimensions over 200 mm wafer scale. Compatible with semiconduct...
