The electrical membrane resistance rho(0) of the marine alga Valonia utricularis shows a marked maximum in dependence on the turgor pressure. The critical pressure, P(c), at which the maximum occurs, as well as its absolute value, rho(0) (max), are strongly volume-dependent. Both P(c) and rho(0) (max), increase with d…

Abstract The structures of the precipitates of free‐radical poly(4‐vinylpyridine) (Vpy), free‐radical poly(2‐Vpy) and isotactic poly(2‐Vpy) with M(II)Cl2 (M = Co, Ni, Cu, Zn) obtained from solution have been investigated. The polymer compounds are similar to the known crystalline monomeric Vpy complexes and, with one…

Abstract Following the discovery that linear polyethylene can be drawn to very high draw ratios to produce oriented fibres and films with ultra‐high initial moduli, a similar study has been undertaken for polypropylene. In particular, the modulus/draw ratio relationship has been obtained for a range of polymers of dif…

The electrochemical and corrosion behavior of nickel in deoxygenated and oxygenated H2SO4 (pH = 0.3) have been studied by the rotating disk technique. Some preliminary corrosion inhibition results of nickel by benzotriazole(BTA) have also been obtained. In the absence of oxygen, three distinct Tafel regions have been…

Abstract Caprolactam was copolymerized with 1,5‐dioxo‐1‐methyl‐4‐azaphosphepane or methylphosphacaprolactam. The molecular weight of the resulting copolymers decreased with increasing concentration of the thermally labile phosphorus moieties. Copolymers based on ≥40% caprolactam were shown to be crystalline by differe…

Since the internal energy $E$ is a monotonically increasing function of the temperature $T$, the moment $M(T)$ can be expressed as a function of internal energy $E$. The corresponding form of $E(M)$ is focused on in this paper. For ferromagnets, the two-dimensional Ising model is used to obtain the exact form of $E(M)…
