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.

fractional flow analysis confirms the advantages of surfactant alternative gas injection (sag) in enhanced oil recovery, but an adsorption phenomenon that has been affected by several factors, weakens the effectiveness of sag injection. in this study, the effects of sacrificial agent, gas phase, and surfactant concentration on adsorption density on silica mineral were investigated by static and...

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...

Vascularization enables multifunctional composites capable of self-healing, thermal regulation, electrical and magnetic modulation, and damage sensing. In this study, the effect of vascular channels on the in-plane tensile properties and damage progression of three-dimensional orthogonally woven textile composites is examined. Vascular channels are manufactured by Vaporization of Sacrificial Co...

SUMMARY Etching of sacrificial material is widely used in surface micromachining technology to form integrated micro mechanical structures. The process typically consists of three steps: the removal of sacrificial-layer material using liquid chemicals, rinsing, and removal of the rinse liquid (drying). The last step is known to cause surface sticking and drastic reduction of device yield. This ...
