A new porosity evolution model is described, along with preliminary results. The formulation makes use of a Cocks-Ashby style treatment of porosity kinetics that includes rate dependent flow in the mechanics of porosity growth. The porosity model is implemented in a framework that allows for a variety of strength mode…
This work shows how multiple non-covalent interactions are employed to control metallosupramolecular architectures and we demonstrate that a ligand, which contains two bidentate domains separated by a ArOH spacer, forms a mesocate when complexed with Ag(I). However, changing this to an ArOCH2CH2Ph spacer unit results…
The effects of the initial sweeping magnetic field (Hi) on the room-temperature magnetoelectric (ME) effect for polycrystalline Z-type hexaferrite Sr3Co2Fe24O41were investigated. The results show that both the electric polarization (P) and ME coefficient (α) can be effectively controlled by Hivia its corresponding ini…
(K0.5Na0.5)NbO3 (KNN) and (K0.5Na0.4Li0.1)NbO3 (KNLN) ceramic were successfully prepared by solid state reaction method. Single phase KNN was obtained from calcined of mixed powders K2CO3, Na2CO3 and Nb2O5 at 700°C/2h and sintered of KNN pellets at 1125°C/4h. Similar with KNN, single phase KNLN was obtained from calci…
A novel BSA-coated inorganic–organic hybrid nano-material with drug delivery ability under stimulation by temperature changes is reported.
The way in which states of a topological insulator (TI) transform from monolayer to bulk is an important issue for applications in spintronics. However, unlike graphite, most layered materials are difficult to exfoliate. Using first-principles calculations, we predict that thallium selenide (TlSe) will be a layered TI…
The aim of this paper is to present a research of magnetic hysteresis loops of a toroidal ferromagnetic core made of electrical steel. The experimental results of induced voltage, magnetic induction and hysteresis loop obtained at different frequencies of the sinusoidal excitation magnetic field have been presented. T…

Abstract. The perennial problem of identifying the “best” scale inhibitor is complicated by the wide diversity of operating conditions found in the field and the variety of available chemistries. To provide some guidance in selecting the proper scale inhibitor, a study was made of several scale inhibitors to map their…
Strategies for incorporating energy-efficiency requirements into building standards have been implemented by governments in developed countries in order to introduce the concept of green nanotechnology. Substituting regular glass windows in residential/commercial buildings with smart windows is the objective. The smar…
Surface pre-treatment is one of the critical treatments for surface modification of aluminium (Al). In this study, pre-treatment of Al surface involved three stages; (1) cleaning (polishing and degreasing), (2) chemical etching (alkaline and acid) and (3) conversion coating (ie: zincate treatment). Cleaning process of…
Intrinsic dissolution testing has been applied for characterization of pure API with respect to its dissolution behavior. The effect of formulation factors and processing parameters on dissolution rate is evaluated by dissolution testing of the final product, which is a time and resource-consuming process. Our objecti…
An L-carnitine derived zwitterionic betaine material was developed. The synthesized L-carnitineMA was the first zwitterionic betaine monomer from natural feedstocks. In the models of Surface coating and hydrogel, the L-carnitineMA material was able to achieve superior anti-fouling performance as good as state-of-the-a…
Hollow silica nanoparticles were prepared through generating a silica layer in spherical polyelectrolyte nanogels, which consisted of a solid core of polystyrene and a shell of crosslinked poly(acrylic acid), followed by removing the core via solvent dissolution.
A series of neutron scattering benchmark measurements were performed on beryllium and molybdenum with the Rensselaer Polytechnic Institute's Neutron Scattering System. The pulsed neutron source was produced by the Rensselaer Polytechnic Institute's Linear Accelerator and a well collimated neutron beam was incident ont…
nanoparticles were prepared through three different facile methods: hydrothermal method, reflux method and ultrasonic method. The pH values of the reaction environment were tuned as the only variable to shape the final products. Colloidal morphologies can be engineered to microflakes, or amalgamations of nanoparticles…
基于金刚石氮-空位色心对精确测量微弱静磁场进行了探索.金刚石氮-空位色心电子自旋的退相干时间高度依赖于外磁场，而不同的退相干特征时间对磁场的灵敏度不同.对金刚石氮-空位色心电子自旋在不同强度外磁场下的退相干过程进行模拟，得到不同退相干特征时间与磁场大小的高准确度关系，提出了基于响应度最高的退相干特征时间测量静态弱磁场大小和方向的方法，并分析了该方法测量静态弱磁场的灵敏度，证明该方法的测量灵敏度比一般磁场测量仪器更高.
Both the acidity of a series of substituted 1,10-phenanthrolines and their reactivity towards N -oxidation are predominantly governed by electronic effects.

In this study, we aim to develop a technology to drive electrically conductive nanofibers made of polymers as an actuator. In a conventional actuator, because the potential is applied to a two-dimensional planar film shape, large electric power is necessary, the displacement is small, and application is difficult.
