In this article, we contrast laser ablation propulsion with photon pressure propulsion. LAP must use repetitive short pulses (~100 ps) for best performance, while PPP requires GW-level continuous (CW) lasers and a lightsail to receive the beam and dr

Ceramic is among the complicated materials to use in the design of fine objects. Complex shapes without any major defect are not easy to produce. In most of the cases, the production of ceramic parts is the results of three steps. Firstly, the “scu

The effects of high pressure carbon dioxide (CO2) on the isotropic transition of three different amphiphilic di-block copolymers, PEOm-b-PMA(Az)n, namely PEO114-b-PMA(Az)40, PEO272-b-PMA(Az)46 and PEO454-b-PMA(Az)47, and on PMA(Az)30 homopolymer have

The effects of nitrogen (N2) pressure on amphiphilic di-block copolymer, PEO114-b-PMA(Az)40, were investigated by scanning transitiometry. The isotropic transition temperature increased with the increase of pressure above 20 MPa. The hydrostatic pres

In PEOm-b-PMA(Az)n amphiphilic diblock copolymers, nanoscale struc- tures exhibit an hexagonal-packed PEOm cylinders arrangement. To precisely investi- gate the role of interfacial interactions between hydrophilic PEOm and hydrophobic PMA(Az)n includ

The present work deals with the interactions between carbon dioxide, used as pressure medium, either in the gas state (GCO2) or in the supercritical state (SCCO2) and amphiphilic di-block copolymers PEOm-b-PMA(Az)n. The effect of pressure on the isot

The knowledge of chemical equilibria in {gas–polymer} systems plays an essential role as regards the safety of transport of petroleum products in polymer-made pipes. Thermophysical properties of thermoplastic semicrystalline polymers are key data f

The purpose of this article is to re-examine the simultaneous measurements of the concentration of a supercritical gas in a polymer and of the concomitant change in volume of the polymer with the coupled VW-pVT technique [Hilic S, Padua AAH, Grolier

The newly developed VW-pVT technique for simultaneously measuring the solubility of a gas in a polymer and the concomitant change of volume of the polymer has been used to estimate the solubilities of N2, CO2, and two hydrofluorocarbons, HFC-134a and
