New spherical codes called laminated spherical codes are constructed in dimensions 2–49 using a technique similar to the construction of laminated lattices. Each spherical code is recursively constructed from existing spherical codes in one lower dimension. Laminated spherical codes outperform the best known spherical codes in the minimum distance sense for many code sizes. The density of a lam...

This article covers the development of thermoplastic extrusion films made poly(vinyl acetate) (PVA) and poly(butyl methacrylate) (PBMA) for use as an inner layer in metal-polymer-metal multiple-layered vibro-damping materials that can work contact with water. The effect amount introduced plasticizer on dynamic properties polymer PVA PBMA is studied example plasticizers from group esters dicarbo...

Multilayer plastic films provide a range of properties, which cannot be obtained from monolayer films but, at present, their recyclability is an open issue and should be improved. Research to date has shown the possibility of using whey protein as a layer material with the property of acting as an excellent barrier against oxygen and moisture, replacing petrochemical non-recyclable materials. T...

The effect of accelerated ageing on the structure and properties of single, metallized and multilayer films used in food packaging was studied, by exposing specimens of the above films to repeated ageing cycles in a weatherometer, under the combined action of UV, humidity and heat. The investigated films were: biaxially oriented polypropylene film (BOPP), metallized BOPP film, polyethylene (PE)...

A new microfabrication process based on a xerographic process is described. A laser printer is used to selectively deposit toner on a polyester film, which is subsequently laminated against another polyester film. The toner layer binds the two polyester films and allows the blank regions to become channels for microfluidics. These software-outlined channels are approximately 6 microm deep. Appr...
