Authors: Wang Jing , Zhang Xiaoyan , Wang Ran , Tan Guoqiang , Su Yuefeng , Wu Feng 
Published: January 2020

Abstract
Silicon/silicon oxides/graphite (Si/SiOx/G) composite with high capacity and excellent cycling performance has been synthesized via high temperature treatment, HF etching and high-energy ball milling for mixture of silicon oxide and graphite. The chemical composition and morphology of the sample was characterized by XRD, SEM and TEM. Large numbers of nanopores were formed in the as-prepared composite, providing three-dimensional transmission pathways for lithium ions and electrons. After 100 cycles, the electrode kept an excellent reversible capacity of 804.2mAh·g-1. The excellent electrochemical properties are mainly attributed to the uniform distribution of silicon particles in amorphous silicon oxide, the buffering effect of porous structure and the improvement of conductivity of the composite by graphite.

Volumetric Displacement in Large Deflection of Symmetrically Layered Piezoelectric Plate under Pretension
Authors: Chen Chunfu , Yu Hsiangjuei 
Published: January 2020

Abstract
The volumetric displacement of a simply supported and symmetrically layered piezoelectric circular plate under lateral load and pretension in large deflection is studied. The approach extends von Karman’s large deflection theory to a layered case and accounts for the associated piezoelectric force terms. The nonlinear governing equations based on the equilibrium were derived, but the arising nonlinear terms in governing equations were dropped, to have an analytical investigation. The solutions were found to be expressible with modified Bessel or standard Bessel functions, depending on whether it is a mechanical-load dominating or piezoelectric-load dominating condition. The previously derived expressions for lateral slopes and deflections are further manipulated to derive the analytical expressions for the volumetric displacements, following strictly the related recurrence relations. The presented approaches are implemented with typical silicon-based layer materials used in a sensing or actuating device. Various dimensions, especially the relative thickness of the piezoelectric layer, as well as different applied voltages and pretensions are considered to have an extensive parametric study. The results indicate that, piezoelectric effect is only apparent in a low pretension condition. Upon reaching a moderate pretension, the pretension effect may always be dominant over the effects of varying the applied voltage and relative thickness.

Authors: Liu Jinghan , Tang Ting , Wei Zhuobin , Li Lingfeng 
Published: January 2020

Abstract
In order to study the damage process of high-piled wharf subjected to underwater explosion, analysis model of high-piled wharf was established. The load characteristics of piles and panel of high-piled wharf were analysed during shock wave propagation and bubble pulse. The failure mode of wharf is basically completed in the first bubble pulse. The damage effect at the top of the pile is the most serious, the damage at the middle is slight, and the damage at the bottom is the weakest. Concrete damage occurs at the connection between pile and beam, beam and longitudinal beam. As the depth of explosive decreases, the damage effect of piles decreases and the damage effect of wharf superstructure increases. When the explosive explodes near the water surface, the wharf panel is damaged seriously and ultimately unusable.

Published: January 2020

Abstract
Paper documents provide important records of human civilization and so understanding the causes of paper document aging is very important to delay the process and prolong the lifespan of paper. This study used an anionic rosin as a sizing agent and aluminum sulphate as a fixing agent, to produce paper with different amounts of aluminum sulphate. The effect of different contents of aluminum ions on the acidification and aging of the paper was studied by accelerated aging experiments. The results showed that the presence of aluminum ions in paper could accelerate the acidification and aging process, and the higher the content of aluminum ions, the worse the durability of paper. In the process of accelerated aging, with increasing aluminum ion content, the rate of decline in the strength and whiteness of paper increased whilst the pH value decreased. Accelerated aging under the same conditions for 15 days caused the pH value, whiteness, tensile index and tear index of paper without aluminum ions to decrease by 14.77%, 3.15%, 7.99% and 11.70% respectively. In comparison, paper which had aluminum sulphate added to 30 kg per ton of paper, showed the decreases of pH, whiteness, tensile index and tear index by 22.62%, 4.35%, 24.66% and 31.07% respectively.

Authors: Targhi Vahid Tavakoli , Omidvar Hamid , Hadavi Seyed Mohammad Mehdi , Sharifianjazi Fariborz 
Published: January 2020

Abstract
Nickel-based superalloys are widely used at elevated temperature applications because of their high corrosion and oxidation resistance characteristics as well as high stability. To improve the hot corrosion resistance of Nickel-based superalloys, different coatings are applied. In this study, nickel-base superalloy Inconel 738LC was coated via a novel hot-dip diffusion siliconizing process and the corrosion behavior was investigated by XRD, SEM and EDS analyses. A sever degradation and poor hot corrosion resistance was detected by the uncoated sample, while the siliconized coated sample possessed high corrosion resistance. It was figured out that the high hot corrosion resistance of the coated sample was due to the formation of SiO2 protective scale in the surface layer which protects the substrate elements in the hot corrosion environment.

Inhibiting degradation of LiCoO2 cathode material by anisotropic strain during delithiation
Authors: Xiang Qianxin , Li Lu , Wang Lijuan , Zhou Chaoyi , Zhang Dongyan , Li Zhimin 
Published: January 2020

Abstract
Lithium cobalt oxides (LiCoO2) possess a high theoretical specific capacity of 274 mAhg−1. However, when LiCoO2 is charged at the voltage higher than 4.2 V, there exist significant structure transition and capacity fade. In this study, we used HRTEM to observe the phase evolution of LiCoO2 cathode material after 100 cycles, and found that LiCoO2 phase would degrade to Co3O4 phase. The phase transition of Co3O4 from LiCoO2 gave rise to lattice expansion, by which the anisotropic strain was proposed by first-principles calculation to inhibit LiCoO2 degradation. Results show that the anisotropic strain via the extension of lattice parameter
c
and the compression of
a
enables to simultaneously impede lattice oxygen loss and structure transition of LiCoO2 during delithiation at high voltage. In this case, the elongation of interplanar spacing also increases the diffusivity of Li ions in LiCoO2, contributing to rate performance.

Published: January 2020

Abstract
This paper examines the gamma-ray shielding features of some selected tellurite-based glasses in the form of xMoO3(100−x)TeO2 (20 ≤ x ≤ 50 mol%). Mass attenuation coefficients (μ

m
) of these glasses have been calculated using Geant4 toolkit and XCOM program for photon energy range of 1 keV—1000 MeV. The correlation factor (R2) between these two methods was found to be almost one. Shielding effectiveness for these glasses has been estimated by computing half value layer (HVL), effective atomic number (Z

eff
), and mean free paths (MFP). It was noticed that the heavy metal oxide of TeO2 plays an important role in improving the shielding effectiveness of the glasses. The Mo20Te80 glass has shown the promising properties to serve for gamma ray protection applications as compared with many conventional concretes and other newly developed glasses.
Design of high strength titanium alloy through finding a critical composition with ultra-fine α phase

Published: January 2020

Abstract
This study presents the design of a high strength titanium alloy based on the idea that the β titanium alloy with critically stable composition could precipitate ultra-fine α phase. An efficient method was used to find the composition of TC21-xV alloy in which ultra-fine α phase could be obtained. It is found that TC21-5V alloy containing ultra-fine α phase and possessing highest hardness could be obtained after solution treatment in the β single-phase region and subsequent aging. The morphology of primary and secondary α phases can be controlled by changing the solution treatment and aging temperatures. Calculation results of driving force and growth rate of secondary α phase show that the growth rate may be a decisive factor for the final size of secondary α phase after solution and aging treatments in the two-phase region. Finally, when the alloy was solution treated at 820 °C and aged at 500 °C, the highest strength of 1540 MPa was obtained. The alloy was solution treated at 820 °C and aged at 600 °C exhibited high strength of 1210 MPa with 11.4% elongation.

AbstractNatural history collections (NHCs) are the foundation of historical baselines for assessing anthropogenic impacts on biodiversity. Along these lines, the online mobilization of specimens via digitization—the conversion of specimen data into accessible digital content—has greatly expanded the use of NHC collections across a diversity of disciplines. We broaden the current vision of digitization (Digitization 1.0)—whereby specimens are digitized within NHCs—to include new approaches that rely on digitized products rather than the physical specimen (Digitization 2.0). Digitization 2.0 builds on the data, workflows, and infrastructure produced by Digitization 1.0 to create digital-only workflows that facilitate digitization, curation, and data links, thus returning value to physical specimens by creating new layers of annotation, empowering a global community, and developing automated approaches to advance biodiversity discovery and conservation. These efforts will transform large-scale biodiversity assessments to address fundamental questions including those pertaining to critical issues of global change.
Reporting Racist Hate Crime Victimization to the Police in the United States and the United Kingdom: A Cross-National Comparison
Authors: Myers Wesley , Lantz Brendan 
Published: January 2020

Abstract
Hate is a global phenomenon as evidenced by recent increases in hate crimes in both the United States and the United Kingdom; unfortunately, these crimes are also substantially underreported in both nations. Following this, this research presents an examination of racially motivated hate crimes and victim reporting to the police in both nations using data from the National Crime Victimization Survey and the Crime Survey of England and Wales from 2003 to 2015. Results indicate that, overall, victim reporting has been increasing in the United Kingdom and decreasing in the United States. Disaggregating by victim and offender race, however, reveals divergent trends such that anti-black hate crime victim reporting is increasing in the United States and decreasing in the United Kingdom. Policy and research implications are discussed.

Published: January 2020

Abstract
We performed post-mortem studies on two patients with advanced Parkinson’s disease 8 and10 years following AAV2-neurturin (CERE120) gene therapy, the longest post-mortem trophic factor gene therapy cases reported to date. CERE120 was delivered to the putamen bilaterally in one case (10 years post-surgery), and to the putamen plus the substantia nigra bilaterally in the second (8 years post-surgery). In both patients there was persistent, albeit limited, neurturin expression in the putamen covering ∼3–12% of the putamen. In the putamen, dense staining of tyrosine hydroxylase-positive fibres was observed in areas that contained detectable neurturin expression. In the substantia nigra, neurturin expression was detected in 9.8–18.95% and 22.02–39% of remaining melanin-containing neurons in the patient with putamenal and combined putamenal and nigral gene delivery, respectively. Melanized neurons displayed intense tyrosine hydroxylase and RET proto-oncogene expression in nigral neurons in the patient where CERE120 was directly delivered to the nigra. There was no difference in the degree of Lewy pathology in comparison to untreated control patients with Parkinson’s disease, and α-synuclein aggregates were detected in neurons that also stained for neurturin, RET, and tyrosine hydroxylase. These changes were not associated with antiparkinsonian benefits likely due to the limited neurturin expression. This study provides the longest term evidence of persistent transgene expression following gene delivery to the CNS and the first human results when targeting both the terminal fields in the putamen as well as the originating nigral neurons.
