The physisorption of gases on surfaces depends on the electrostatic and dispersion interactions with adsorbates. The former can be tuned by introducing charge variations in the material, and the latter can be tuned by chemical substitution. Using atomistic Monte Carlo calculations, the Henry's law constants, and isosteric heats of adsorption of CH(4), CO(2), N(2), O(2), H(2)S, SO(2), and H(2)O ...
The linear and crosslink types of PPH provide different topological structures, in which the type shows much higher Li transfer storage. Polymer materials offer controllable structure-dependent performances separation, catalysis drug release. Their molecular structures can be precisely tailored to accept + for energy storage applications. Here design sp 2 carbon-based polyphenylene (PPH) with h...
the manufacturing organizations today are having a competition of supply chain versus supply chain. existing research work fails to relate human metrics with supply chain performance. the authors intend to empirically assess the effects of human metrics on supply chain performance in the context of indian manufacturing organizations. a rigorous literature review has identified 12 variables. the...
background: the purpose of this study was to investigate the ratio of electromyography (em g) activities of the vastus medialis obliqus (vmo) and vastus lateralis (vl) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (ok c) and closed kinetic chain (ckc). methods: the dominant knees of 44 healthy female subjects (mean age: 24.84 with range: 20-...
High-performance fibres are fibre materials that exhibit at least one extraordinary property compared to conventional materials. That is frequently related excellent stability against certain influences such as fire, heat, chemicals or light. Also, a high mechanical strength often of high-performance fibres. Nevertheless, it should be noted weaknesses in addition their advantages. This review p...
Reinforcement of flexible fibre reinforced plastic (FRP) composites with standard textile fibres is a potential low cost solution to less critical loading applications. The mechanical behaviour of FRPs based on mechanically bonded nonwoven preforms composed of either low or high modulus fibres in a thermoplastic polyurethane (TPU) matrix were compared following compression moulding. Nonwoven pr...
The electrooxidation of catechols, catecholamines and NADH at conventional electrode materials is generally characterized by high degrees of irreversibility as well as strong adsorption and, hence, fouling by reactants and/or products of the reactions. On the contrary, the rates of the electron transfer are highly catalysed by the use of conducting polymer films, such as poly(3-methylthiophene)...
mammalians express several subclasses of the igg molecule. in human being there are four homologous igg subclasses, each of which is structurally unique and has different functions. quantification of igg subclasses is fundamental to clinical assessment and diagnosis of many diseases as such assessments depends on the availability of subclassspecific antibodies (abs), particularly monoclonal ant...
nowadays, in turbulent and violate global markets an agile supply chain (asc) network is frequently considered as a dominant competitive advantage for survival. to achieve the competitive advantage, companies must align with suppliers and customers to streamline operations, as well as agility beyond individual companies. there are many definitions and models about agile supply chain and most of...
