Microscopic Experimental Investigation on Shear Failure of Solder Joints
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-12)
A microscopic investigation has been made on the shearing of one leaded and two lead-free solders by using an in situ SEM method. A shear lap joint specimen is designed and fabricated to accommodate a thin layer of solder ...
Ring-opening polymerization of epoxy end-terminated poly(ethylene oxide) as a route to highly crosslinked materials with exceptional swelling behavior (II)
(John Wiley & Sons, Ltd., 2007-08)
Highly swellable poly(ethylene oxide) (PEO) gels were prepared by anionic ring-opening polymerization of diepoxy end-capped PEO (3400 g mol −1 ) and PEO (8000 g mol −1 ) using dianionic glycerol and glycolic acid initiators ...
Focus on function: Single molecule RNA enzymology
(Wiley Subscription Services, Inc., A Wiley Company, 2007-12-05)
The ability of RNA to catalyze chemical reactions was first demonstrated 25 years ago with the discovery that group I introns and RNase P function as RNA enzymes (ribozymes). Several additional ribozymes were subsequently ...
Low-Temperature SCR of NO with NH 3 over USY-Supported Manganese Oxide-Based Catalysts
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-04)
A series of catalysts of manganese oxide, manganese–cerium and iron–manganese oxide supported on USY (ultra-stable Y zeolite) were studied for the low-temperature selective catalytic reduction (SCR) of NO with ammonia in ...

Representation of Somatosensory Evoked Potentials Using Discrete Wavelet Transform
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-04)
Objective. Somatosensory evoked potentials (SEP) have been shown to be a useful tool in monitoring of the central nervous system (CNS) during anaesthesia. SEP analysis is usually performed by an experienced human operator. ...
Cluster distance geometry of polypeptide chains
(Wiley Subscription Services, Inc., A Wiley Company, 2004-07-30)
Distance geometry has been a broadly useful tool for dealing with conformational calculations. Customarily each atom is represented as a point, constraints on the distances between some atoms are obtained from experimental ...
Fuel Cell Membrane Electrode Assemblies Fabricated by Layer-by-Layer Electrostatic Self-Assembly Techniques We acknowledge the UM OVPR office for a faculty seed grant awarded to the first author. We also thank Professor Phillip Savage for generous use of lab space and equipment.
(WILEY-VCH Verlag, 2008-10-09)
High activity, carbon supported Pt electrocatalysts were synthesized using a supercritical fluid method and a selective heterogeneous nucleation reaction to disperse Pt onto single walled carbon nanotube and carbon fiber ...
Response of a biphasic poly( n -hexyl isocyanate)/ p -xylene solution to applied high electric fields
(Wiley Subscription Services, Inc., A Wiley Company, 2005-05-01)
The effect of a high electric field on a solution of a lyotropic liquid-crystalline polymer, poly( n -hexyl isocyanate) in p -xylene, was studied. The application of a high-voltage alternating-current electric field to ...
Multicompartmental Microcylinders
(WILEY-VCH Verlag, 2009-06-08)
FarbenprÄchtige SÄulen : Eine einfache und dabei skalierbare Methode zur Herstellung multikompartimentalisierter Mikrozylinder, bei denen innerer Aufbau, SeitenverhÄltnis und OberflÄche gezielt eingestellt werden kÖnnen, ...
