The present study describes the development of a continuous impedance monitoring system. Zinc oxide (ZnO) thin film electrode array was developed over a glass substrate. Two consecutively placed electrodes were connected with copper wires and the impedance properties of the electrode-D-glucose solutions were studied i…
To overcome the scarcity of organs available for clinical transplantation, whole-organ engineering has been attempted in recent years. In this approach, cellular components of an organ are totally removed through arterial perfusion with a detergent, and the resulting extracellular matrix scaffold serves as a template…

Soil clays (< 2,000 nm) (SC) and soil nanoclays (< 100 nm) (SNC) were used as adsorbents for removal of Cu(II) from aqueous solution. The experiments were conducted with variables including pH, interaction time, concentration of Cu(II) and temperature. Four kinetic models have been employed to investigate adsorption m…

In the paper presented here the optimization of Halbach arrays as storage media for mechanical potential energy is investigated with numerical simulations using FEMM and analytical calculations using the Maxwell stress tensor. Two opposing Halbach arrays form a "magnetic spring" and mechanical potential energy is stor…
摘要： 高速干切滚齿工艺消除了切削油/液的使用，是一种绿色高效的齿轮制造工艺。切削热伴随着高速干切滚齿工艺全过程且区别于传统湿式滚切工艺，是造成干切滚刀磨损和机床热变形的重要因素，直接影响制造成本和加工精度。根据干切滚刀周期性断续传热特性，综合考虑切削热在切屑、工件、干切滚刀、冷却介质以及滚齿机床加工空间的传递规律，提出将高速干切滚齿工艺系统切削热的发生与传递全过程划分为三个阶段的研究思想，从关系模型和热传递方程两个层面建立了高速干切滚齿工艺系统切削热全过程传热模型，包括切削接触界面热传递、切削区域热传递和机床加工空间热传递三个阶段的模型，然后基于工艺仿真试验对所建模型进行了应用研究，揭示了高速干切滚齿工艺系统的切削热在工件、干切…
This work provides detailed spectroscopic, elemental and contact angle analyses for the treatment of borosilicate glass covers. The glass surface was first treated with strong acid to promote hydroxylation, followed by silanisation using 3- \n(trimethoxysilyl)propyl methacrylate. Attenuated Total Reflectance Fourier T…
Numerical simulation is a valuable tool to help investigate complex multiphysics problems of engineering and science.

In this field, numerical simulat…
We investigate the propagation of electron wavepackets in single-walled carbon nanotubes via a Lindblad-based density-matrix approach that enables us to account for both dissipation and decoherence effects induced by various phonon modes. We show that, while in semiconducting nanotubes the wavepacket experiences the t…
Taking the flexural wave propagating in elastic thin plate as an example, we investigate the mechanism for gap opening in the resonator-based acoustic metamaterials. Results show that the band gap in such a kind of structure depends not only on the abrupt phase change of the wave when it is scattered by the resonators…
Dy2Ti2O7 is at present the cleanest example of a spin-ice material. Previous theoretical and experimental work on the first-order transition between the kagome-ice and the fully polarized state has been taken as a validation for the dipolar spin-ice model. Here we investigate in further depth this phase transition usi…
Porous anodic alumina thin films with rainbow rings were fabricated in oxalic acid electrolyte by one-step electrochemical oxidation of Al sheet.
