    Abstract: The authors and editors of this volume state that with the intensive growth of global industrialization and urbanization, the consumption of various resources and materials, such as energy, minerals, and even water, is increasing at an amazing speed, which poses great pressure on material resources. In addition, the massive utilization of materials has led to low efficiency, resulting in great wastes of resources as well as serious environmental pollutions and degradation, which has severely hindered the sustainable development of economy and society. In order to transit to sustainable development, it is necessary to improved resource efficiency, and circular economy and waste valorization are the best alternative ways for achieving this goal. This book aims to provide an in-depth description of circular economy and waste valorization, make assessments for circular economy and waste valorization in different regions and countries and determine the technological pathways and roadmap for achieving circular economy and waste valorization. More specifically: (1) Conceptions and Theories: Concepts and definitions of circular economy and waste valorization and their nexus and contributions to sustainable development. (2) Policy and Practice: Measurement and assessment of performance or sustainability for implementing circular economy and waste valorization. (3) Pathways and Prospects: Identification and prioritization of the barriers, strategies, technologies, and pathways for achieving circular economy and waste valorization. The book systematically and comprehensively introduces the definitions, concepts, framework and nexus of circular economy and waste valorization, analyzes and measures their performance and sustainability and provides the methods for investigating and prioritizing the barriers and strategies and determining the pathways and roadmap for their development. .

    Notes: Sodium superionic conductor, NASICON ceramic (Na1+xZr2SixP3-xO12, x=2), washot-press sintered under different temperatures and the electrical properties of the obtained differentsamples were investigated. Results show that the relative density of the ceramics can be improvedby hot-press process efficiently and the crystal size of the samples are closely related to sinteringtemperature. With the increase of sintering temperature, both the density and the crystal size ofsamples increase obviously, resulting in the increase of ionic conductivity of samples as thesintering temperature. When the sintering temperature reaches 1150oC, the ionic conductivity ofsample is as high is 3.6×10-3S/cm, which is obviously higher than that of sample sintered at 1000oC(2.13×10-3S/cm). As the frequency increase, the real parts and the imaginary parts of complexdielectric constants for all the samples decrease in 8.2 GHz~12.4GHz frequency band. The ceramicsobtained at the higher temperature possess the higher dielectric constant

    Notes: By introducing ZrO2 (3Y) micron powder into the thermit, Al2O3/18%, 21%, 24%, 27% and30%ZrO2 composite ceramics were obtained from in-situ growth in the melts produced by combustionsynthesis. As the volume fraction of ZrO2 is below 27%, the ceramics is comprised of lath-shaped androd-shaped α-Al2O3 matrix, within the rod-shaped grain the nano-micron fibers are oriented in essentiallythe same direction. As volume fraction of ZrO2 is over 27%, the ceramics is mainly composed oflamina-shaped grains with alternating α-Al2O3 and t-ZrO2 layers. The flexural strength and the fracturetoughness measured simultaneously the maximum values with increasing volume fraction of ZrO2 to 24%,indicating that flexural strength and fracture toughness are simultaneously under the control ofrod-shaped grains in which ZrO2 nano-micron monocrystal fibers are embedded

    Notes: Al2O3/24%ZrO2 composite, which is mainly composed of lath-shaped and rod-shaped α-Al2O3matrix containing ZrO2 nano-micron fibers, was obtained from in-situ growth in the melts produced bycombustion synthesis. The results from XRD, SEM and EPMA showed that, besides the rod-shaped andlath-shaped α-Al2O3 grains, there are also t-ZrO2 or m-ZrO2 independent phases and Cr metallic particlesat the boundaries of rod-shaped grains. The strength and toughness were measured to be 1186 MPa and12.8MPa·m0.5 respectively. The procedure for toughening ceramics relies on coordinated action ofmultiple toughening mechanisms involving reinforcement-induced toughening by ZrO2 nano-micronfibers, deflection-induced toughening, stress-induced transformation toughening, crack-bridgingtoughening by lath-shaped α-Al2O3 grains as well as deformation-induced toughening by Cr metallicparticles, and promises the occurrence of a sharp rising R-curved behavior

    Notes: In this paper the effect of isothermal forging process parameters on the microstructure andthe mechanical properties of TA15 titanium alloy was researched. The results of the tests indicatethat, in the range of temperature of 850 ºC~980 ºC and deformation degree of 20%~60%, with theincrease of temperature or deformation, as the reinforcement of deformation recrystallization, theprimary α-phase tends to the spherical shape and secondary α-phase transforms from the acicularshape to fine and spherical shape with disperse distribution, which enhance the tensile properties atroom and high temperature. With the increment of forging times, the spheroidization of primaryα-phase aggrandizes and secondary α-phase transforms from spherical and acicular shape to widestrip shape, which decrease the tensile properties at room and high temperature. The preferableisothermal forging process parameters are temperature of 980 ºC, deformation degree of 60%, andfew forging times

    Notes: By introducing ZrO2(4Y) powder of suitable content into the thermit and based onoxidation-reduction reaction of the thermit and liquid-liquid phase separation of ceramics/metalunder gravity, Al2O3/ZrO2(4Y) composite ceramics have been prepared through melt-growth witheutectic reaction under high degree of undercooling from SHS process. It has been found that theceramics were composed of major rod-shaped sapphires with 8.0~12.0 aspect ratios and minorplate-like α-Al2O3 grains, and within the sapphires t-ZrO2 nano-micron fibers were embedded.Flexural strength and fracture toughness were measured to be 1256MPa and 13.2MPa·m1/2. It wasobtained that a number of low energy interfaces (the interface distance on nano-micron scale) betweentwo Al2O3/ZrO2 (4Y) phases and the strong compressive residual stress in the sapphires made thesapphires reinforced, forcing the crack to propagate along the rod-shaped sapphires; meanwhile,crack-bridging and pull-out of the sapphires, crack - bridging and frictionally interlocked effects ofplate-like α-Al2O3 grains in the wake of crack tip also rendered the crack stabilization to arise

    Notes: The electronic structure and local magnetic properties of the MnSb compound with or without substituted Pt atoms are calculated using the spin-polarized discrete variational method within local-density-functional theory and multiple embedded clusters models. Calculated charge transfer, spin moments and density of states of MnSb without doping Pt atoms agree well with experiments and augmented sphere wave calculations for MnSb crystal. Finally, the electronic structure and spin moments of MnSb doped with different concentrations of Pt atoms are calculated. © 1997 American Institute of Physics.

    Mesoporous AlPO4 Glass from a Simple Aqueous Sol–Gel Route (2005)

    Notes: Transparent and colorless AlPO4 gel and glass are prepared via a simple aqueous sol–gel route using aluminum lactate and phosphoric acid as precursors. The stoichiometric AlPO4 glass derived from this sol–gel route has a mesoporous structure with a surface area of 504 m2/g after calcination to 600°C. With increasing gel-to-glass processing temperature, the average degree of P/Al connectivity increases. After sample calcination at 600°C for 4 h, 27Al MAS NMR spectra indicate that aluminum is almost completely converted into AlO4 units. 27Al{31P} rotational echo double resonance and 31P{27Al} rotational echo adiabatic passage double resonance NMR experiments as well as 27Al and 31P MAS NMR results further confirm that the prepared AlPO4 glass has a three-dimensional network based on alternating Al(OP)4 and P(OAl)4 tetrahedral units in analogy to the local structure of crystalline AlPO4.
