Low-stress transfer bonding using floatation

A novel method for transferring thin, large-area polymer layers from a mould and its subsequent bonding to a destination substrate is presented here. Buoyancy is used for transfer via floatation to allow the release of internal stress in the polymer and to avoid induced strain. Additionally, floatation leads to wrinkle-free contact between the polymer layer and its destination substrate, an imp...

Capillarity and Archimedes’ Principle of Floatation

We consider some of the complications that arise in attempting to generalize a version of Archimedes’ principle of floatation to account for capillary effects. The main result provides a means to relate the floating position (depth in the liquid) of a symmetrically floating sphere in terms of readily observable geometric quantities. A similar result is obtained for an idealized case correspondi...

NOVEL REAGENTS FOR CREATINE KINASE

The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...

Serum lipoprotein measurement--liquid chromatography and sequential floatation (ultracentrifugation) compared.

An HPLC method [J. Biochem. (Tokyo) 91:1381, 1982] was used for evaluating serum lipoproteins, with on-line monitoring of either cholesterol or phospholipids. Five well-distinguished lipoprotein fractions were observed, based on their particle sizes. Serum of 15 normal persons, 12 subjects with various types of hyperlipidemia, 20 patients with various liver diseases, and two cases of familial L...
