The livestock industry on Taiwan is well-developed, and due to in a subtropical region, temperature and humidity of the environment cause the bacteria growth in livestock farms, so antibiotics are often used in the treatment to prevent from the diseases of livestock and poultry. These excreta produced by the livestock…
Attapulgite was modified by acidification, and main factors such as modification condition, dosage, solution pH value and time of adsorption were studied for adsorption efficiency of attapulgite. Under optimum adsorption conditions(dosage of modified attapulgite was 0.500g/25mL, waste water pH=4, and time of adsorptio…
Recent advances in microstructured materials have given rise to many new types of composites that exhibit original and interesting physical properties. For example, a nanocomposite made of carbon nanotubes inside a polymer matrix shows exceptional electromagnetic interference shielding effectiveness when foamed. Howev…
Ba0.5Sr0.5Co0.8Fe0.2O3 – δ is a mixed ion-electron conductor with high application potential as high-temperature gas separation membrane. However, in practical use the integrity of this brittle perovskite is challenged by the mechanical boundary conditions of transient temperature exposure. Moreover, long term failure…
As part of the celebrations marking its Centenary, the Biochemical Society held a joint meeting in Shanghai with the Chinese Protein Society to commemorate the many long-standing collaborations between biochemists from the U.K. and China. Under the overall theme of structural biology of proteins, presentations coverin…

One of the grand goals of materials science is to be able to design, build, and understand functional materials with a precision that is equal to the size of the smallest possible entity, i.e. the size of an atom. This atomic‐scale engineering of materials is a difficult, if not impossible, feat to achieve in three di…
The coupled-cluster method is applied to the spin-1/2 antiferromagnetic XXZ model on a square lattice by employing an approximation which contains two-body long-range correlations and high-order four-body local correlations. Improvement is found for the ground-state energy, the sublattice magnetization and the critica…
One of the primary applications of polymer based cellular solids is to act as an energy absorbing material during impact where compressive strain rates may reach 500-800/s. In reality, impacts occur over a wide range of temperatures and velocities at different angles of incidence. Understanding and modelling the behav…
In this paper, the computational predictions of crack initial breakpoint and deflection angles under bend and torsion loading conditions are investigated in conjunction with the modified virtual crack closure integral (MVCCI)-method by using the all fracture modes (AFM) specimen and commercial software ANSYS. The sepa…
Abstract The cover picture shows how the HOMO and LUMO energy levels of hydrazone end‐capped pyrrolic squaraine compounds for organic photovoltaic devices can be efficiently tuned by means of the substituent effect. The capability of tuning the LUMO position is of outmost importance to obtain efficient light‐induced c…
This paper provides an original experimental characterization of the shakedown state of a shape memory alloy structure under cyclic pseudo-elastic loading. This analysis is performed through the observation of the dissipated energy at a macroscopic scale as well as the temperature on the surface of the sample through…
ZnO nanoparticles (NPs) have attracted increasing attention recently because it is nontoxic, chemically stable towards air, and inexpensive luminescent material instead of the GaN- based structures. However, in general, two emission peaks appear in the ultraviolet and visible region in the photoluminescence spectra of…
Stress corrosion cracking of 7050 aluminum alloys and ASTM A470 steel in the turbo expander and steam/gas turbine industry can cause expensive catastrophic failures, especially for turbo machinery systems performing in hostile, corrosive environments. Commercially available inhibitors were investigated for their effec…
Advanced finite element analysis (FEA) is carried out to simulate the off-axis crushing process of glass/epoxy twill/weave composite box structures. The FE results were compared to relevant experimental result and it was shown that the applied model is capable to predict the damage behaviour and energy absorption of c…
The determination of monotonic mechanical properties and high cycle fatigue parameters of high chromium steel (HCS) is presented. The monotonic mechanical properties (ultimate compressive and ultimate tensile strength) are determined using standardized testing procedures according to DIN 50125 standard. The high cycle…
In the present study, the rare earths element YbCl3 was added into the Zn-epoxy coating, and the MIC behavior of the low alloy steel specimen with YbCl3-Zn-epoxy coating in the sulfate-reducing bacteria (SRB) solution was investigated and compared with the specimen of Zn-epoxy coating. Experimental results show that b…
In this study, with a view to improve the mechanical properties, the influence of the change in the micro-structure, crystal phase and mechanical properties were evaluated, by changing the amount of one of the sintering additives, Al 2 O 3 and the HIP sintering conditions, from the viewpoint of the micro-structure con…
A mechanical model of the visco-elastic compressible material is established in order to investigate the viscous effect in quasi-static growing crack-tip field. The constitutive equations on the visco-elastic compressible material are deducted. Through asymptotic analysis, it is shown that in the stable creep growing…
The recent rewriting of the Bazant's Size Effect Law which has suggested the existence of an additional asymptotic regime for intermediate structure sizes is compared to numerical simulations of fracture of geometrically similar notched structures of different sizes. The quasibrittle failure is simulated through Cohes…
