    Abstract: Neurons communicate with each other by releasing neurotransmitters. This book provides comprehensive coverage of the molecular mechanisms involved in neurotransmitter release. The topics covered in the book range from the architecture and cytomatrix proteins of presynaptic sites, to the modes of synaptic vesicle exocytosis (full-collapse and kiss-and-run), and from the key molecules mediating synaptic vesicle fusion (SNAREs) to those that closely interact with them (UNC-13/Munc13, UNC-18/Munc18, tomosyn, and complexins). The book also delves into the calcium sensors of synaptic vesicle fusion (synaptotagmins and Doc2s), the sources of calcium that trigger synaptic exocytosis (voltage-gated calcium channels and ryanodine receptors), and the regulation of neurotransmitter release by potassium channels, cell adhesion molecules, lipids, aryl hydrocarbon receptor-interacting protein (AIP), presenilins, and calstabins. To aid in understanding and illustrate key concepts, the book includes sufficient background information and a wealth of illustrations and diagrams. The new edition includes major updates to previous chapters, as well as several new chapters that reflect the recent advances in the field. Comprehensive and cutting-edge, Molecular Mechanisms of Neurotransmitter Release, 2nd edition, is a valuable learning resource for neuroscience students and a solid reference for neuroscientists.

    Notes: In this paper, the lower and upper bounds of Young’s modulus and Poisson ratio are determinedby the effective stress method and effective strain method from material mechanics. The effectiveheat flux method based on the hypothesis of equivalent temperature difference and the effectivetemperature difference method based on the hypothesis of equivalent heat flux are proposed, the lowerand upper bounds of the thermal conductivity of ceramic/metal composite material are determinedsimilarly. The result shows that the property values of ceramic/metal composites calculated from currenttheoretical property formulas are within the lower and upper bounds determined by the above methods

    Notes: Four Coating schemes and two substrate materials are designed to evaluate the characteristicsof the ceramic/metal gradient thermal barrier coating. The gradient coating is successfully prepared byplasma spray with single torch and single feeder. The coating performance is evaluated by observingmicrostructure, measuring thermal shock resistance and thermal residual stress. The coatingmicrostructure is observed by scanning electron microscope (SEM). Diffractive peaks for the gradientcoating are got at different zone by X-ray spectroscopy (XRS). The thermal shock experiment shows thatthe thermal shock resistance property of the gradient coating is better than that of the non-gradient coating.The measurements of thermal residual stresses in different coating schemes are carried out byhole-drilling method, the results show that compressional stress presents on 1Cr18Ni9Ti substrate andtensile stress presents on 2Cr13 substrate

    Notes: In the current paper, a macroscopic differential model is constructed on the basis of theLandau theory of the first order phase transformation. Hysteresis loops and butterfly-shapedbehaviors are modeled as a consequence of polarizations and orientation switchings. A non-convexfree energy function is constructed to characterize different polarization orientations in thematerials. Polarizations and orientation switchings are modeled by formulating the system stateswitching from one equilibrium state to another, as differential equations. The hysteresis loops andbutterfly-shaped behaviors are successfully modeled. Comparison of the model results with theexperimental counterpart is also presented

    Notes: A kind of gradient thermal and environmental barrier coating applied in internal combustionengine is brought forward to improve its reliability, emission and efficiency. The multi-layer plate andcylinder models are established for the simulations of heat transfer and thermal stress in the coatings.Both the theoretical and the numerical analysis with multi-layer cylinder model with coating inside arecarried out and compared. The results show good agreement

    Notes: A thermal shock experiment is designed to explore the thermal shock properties ofceramic/metal gradient thermal barrier coating. The specimens are heated up by oxygen-acetylene flameand cooled by water spray. The experiment procedure includes two stages, heating the specimen from theinitial temperature 30°C for 40s, and then cooling for 20s. The heat transfer and the associated thermalstresses produced during the thermal shock procedure are simulated by finite element method.Experimental results indicated that the specimen of gradient coating behaves better in thermal shockexperiments, which agree with the results of simulation

    Notes: Aiming to study the surface integrity of an ultra-high strength alloy in high speed millingprocess, 2K factorial design experiments were conducted to explore the effects of cutting parameters,such as cutting velocity, feed rate and depth of cut, on microstructure, microhardness and residualstress in the sub-surface layer. The following conclusions could be drawn from this paper within therange of cutting conditions: The cutting parameters could significantly influence the microstructureand microhardness in the surface and sub-surface layers, and the original fine martensite of the surfaceand sub-surface layer might be transformed into the over-tempered martensite, under-temperedmartensite, secondary troostite, and tempered sorbite; Compressive residual stress distributions withdifferent maximum stress values in the sub-surface layer of machined surfaces could emerge in highspeed cutting process; the properly arranged cutting condition could achieve ideal surfacecharacteristics and surface integrity

    Notes: Al-Si metal anode was fabricated by cold-press sintering with Al and Si as embeddedpowder in argon atmosphere. The anti-oxidation in the air and anti-corrosion in molten cryoliteproperties of Al-Si metal anode at high temperature were examined. The experimental results showedthat the oxidation kinetics curve obeyed the parabolic law. The corrosion behavior Al-Si metal anodewas studied in electrolysis test. The electrolyte consisted of Na3AlF6(90 wt%),CaF2(5 wt%) andAl2O3(5 wt%) which corresponded to molecular ratio of 2.4. The results indicated that the cell voltagewas stable and the electric polarized corrosion rate was higher than the static corrosion rate of metalanode. SEM photographs showed an oxidation film formed in the surface of Al-Si metal anode whichcan obstruct the further corrosion in molten cryolite. It may be concluded that Al-Si metal anode hasgood combination property and can replace the carbon anode in the aluminum cell

    Notes: In this study, superplastic tensile tests were carried out for Ti-6Al-4V alloy using differentinitial grain sizes (2.6 μm, 6.5μm and 16.2 μm) at a temperature of 920°C with an initial strain rate of1×10-3 s-1. To get an insight into the effect of grain size on the superplastic deformation mechanisms,the microstructures of deformed alloy were investigated by using an optical microscope andtransmission electron microscope (TEM). The results indicate that there is dramatic difference in thesuperplastic deformation mode of fine and coarse grained Ti-6Al-4V alloy. Meanwhile, grain growthinduced by superplastic deformation has also been clearly observed during deformation process, andthe grain growth model including the static and strain induced part during superplastic deformationwas utilized to analyze the data of Ti-6Al-4V alloy

    Notes: The microstructures of Ti6Al4V alloy after hydrogenation have been investigated andanalysed by optical microscopy (OM), X-ray diffraction (XRD) and transmission electron microscopy(TEM), and the influence of hydrogenation on the hardness of α and β phases has been analysed bymicrohardness testing. The microstructure observation revealed that δ hydride (fcc structure)precipitated in the specimens with 0.278 wt.% and 0.514 wt.% hydrogen, and a lot of dislocations andtwins have been found simultaneously. The diffraction peaks moved to the lower angles because ofthe lattice expansion of β phase with the solution of hydrogen atoms. The result of microhardnesstesting shows that the hardness of α and β phases increases synchronously with increasing ofhydrogen and the increment of β is larger than that of α. It is considered that the formation of δhydrides, lattice defects and alloying element diffusion are the major factors leading to themicrohardness change
