We present resistivity measurements of Mott insulator NiS2 single crystals after heat treatment. We find a strong increase of the low temperature resistivity that relaxes back towards the pristine behaviour over several days with a time constant of 45 h at room temperature. The low temperature resistivity has previously been shown to be dominated by surface conduction [1]. Consequently, the cha...

This study explores the relationship between happiness and air pollution in Britain using data from the British Household Panel Survey (BHPS). The effects of air pollution on individuals’ happiness are estimated and their monetary value is calculated. In particular, three air pollutants are examined in this paper; the sulphur dioxide (SO2), the ground-level ozone (O3) and the nitrogen dioxides ...

some studies have already addressed the effects of occupational organic solvent exposure on the visually evoked potentials (veps). visual system is an important target for sulphur mustard (sm) toxicity. a number of iranian victims of sulphur mustard (sm) agent were apprehensive about the delay effect of sm on their vision and a possible delay effect of sm on their visual cortex. this investigat...

A model of multiparticle production in hadronic collisions at ultra-relativistic energies, based on the assumption of independent string fragmentation, reproduces the rapidity spectra of Λ and Λ̄ in sulphur-sulphur collisions reported by the NA35 Collaboration. This is achieved after a reconsideration of the intermediate multi-string states and the structure of the diquarks. Nuclear stopping pow...

The present work is aimed at examining carbon steel oil pipelines corrosion using three natural extracts (Eruca Sativa, Rosell and Mango peels) that are used as inhibitors of different concentrations ranging from 0.05-0.1wt. %. Two sulphur compounds are used as corrosion mediums. Weight loss method was used for measuring the corrosion rate of the carbon steel specimens immersed in technical whi...

The sulphate assimilation pathway provides reduced sulphur for the synthesis of the amino acids cysteine and methionine. These are the essential building blocks of proteins and further sources of reduced sulphur for the synthesis of coenzymes and various secondary compounds. Several recent reports identified the adenosine 5'-phosphosulphate reductase (APR) as the enzyme with the greatest contro...

Magnesium metal is an ideal rechargeable battery anode material because of its high volumetric energy density, high negative reduction potential and natural abundance. Coupling Mg with high capacity, low-cost cathode materials such as electrophilic sulphur is only possible with a non-nucleophilic electrolyte. Here we show how the crystallization of the electrochemically active species formed fr...
