Research of Self-assembled Monolayer of Alkanethiol for Corrosion Protection of Brass
International Journal of Electrochemical Science, 2015 Self-assembled monolayers (SAMs) of alkanethiol have been fabricated on an anodized surface of brass. The inhibition behavior of SAMs of alkanethiol on brass in seawater had been investigated by electrochemical impedance spectroscopy (EIS) and ...

Parameters optimization of intermediate fluid vaporizer based on mixed working fluid
You-qi chuyun, 2020 Intermediate Fluid Vaporizer (IFV) is a key heat exchange device for off-shore floating LNG receiving terminals. Based on the heat transfer theory, a coupled heat exchange calculation model for multiple heat exchangers was established, and mixed working ...

HEAT EXCHANGE AND ENDOTHERMY IN PROTODONATA [PDF]
Evolution, 1982 Since the thought-provoking papers by Ostrom (1969) and Bakker (1971) the question has been raised repeatedly of whether dinosaurs were conventional poikilothermic or heliothermic reptiles, were "inertial" homeotherms (Spotila et al., 1973; McNab, 1978) by virtue of their enormous size, or were, rather, endotherms with metabolic rates comparable to ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Study of Tube Pretension Effects on the Strength of the Flat-Round Tubesheet in a Quench Boiler
ChemEngineering, 2022 A quench boiler is the key equipment in ethylene production for the rapid cooling of high-temperature cracking gas. In the boiler, heat transfer is occurs between the hot cracking gas passing through the inner heat exchange tubes with an average ...

Asymptotics of the heat exchange
Journal of Functional Analysis, 2004 If \(K\subset \mathbb R^{m}\) is a compact subset, we set \(E_{K}(t) = \int_{\mathbb R^{m}\setminus K} u(x,t)\,\roman dx\), where \(u\) is the (unique) weak solution to the heat equation \(\partial_{t}u = \Delta u\) in \((\mathbb R^{m}\setminus K)\times \mathbb R_+\) with initial condition \(u(\cdot,0) = 0\) and boundary condition \(u=1\) on \(\partial
