Maskless Fabrication of Nanowells Using Chemically Reactive Colloids

Oct 16, 2011
Darrell Velegol
We describe a maskless process for the fabrication of nanowells on a silicon substrate using chemically reactive nanoparticles. Positively-charged amidine-functionalized polystyrene latex (APSL) colloids are adhered onto a silicon wafer, and hydrolysis of the particles' amidine groups generates...

Solubility of CO2 and H2 In PDMS and PEGDME At 25 – 120 Oc

Oct 16, 2011
Robert M. Enick
Advanced gasification power plants will employ the water-gas shift reaction to produce a high pressure gas-phase mixture containing CO 2 , H 2 and water. This shifted syngas mixture at elevated pressures provides ample driving force for the use of physical solvents that will selectively absorb, but...

High Absorption Performance of HCl in 1-Octyl-3-Methylimidazolium Chloride

Nov 8, 2010
Suojiang Zhang
Incineration of wastes and combustion of chlorine-rich coal are the major sources of local and global environmental pollution related to hydrogen chloride (HCl) emission. At the same time, HCl is a common tail gas in chemical industry such as PVC and Freon production. HCl is regarded as the most...

Thermodynamics for the Practicing Engineer

June, 2009
Thermodynamics for the Practicing Engineer, as the title suggests, is written for all practicing engineers and anyone studying to become one. Its focus therefore is on applications of thermodynamics, addressing both technical and pragmatic problems in the field. Readers are provided a solid base in...

Fluid Flow for the Practicing Chemical Engineer

June, 2009
This book teaches the fundamentals of fluid flow by including both theory and the applications of fluid flow in chemical engineering. It puts fluid flow in the context of other transport phenomena such as mass transfer and heat transfer, while covering the basics, from elementary flow mechanics to...

A Novel Method for Enhanced Heat Removal from Closed Systems

Nov 17, 2008
Ranga Narayanan
Removal of heat from confined cabins and space habitats is of immense importance to NASA in order to ensure proper thermal control. The design of important thermal subsystems for future applications as in boilers, condensers, evaporators, heat exchangers etc will involve complicated fluid flow...

Success and Prospects in Thermodynamics

Nov 16, 2008
Peter T Cummings
Accurate thermodynamic models are essential to any chemical engineering endeavor. In this presentation, Cummings reviews some of the more important developments in the history of thermodynamics; from Gibbs and van der Waals in the nineteenth century, to the statistical mechanicians of the twentieth...

Harness Electricity to Operate Valves

June
