A low-volatile organic compound, screen-printable silver ink system capable of also performing as a conductive adhesive was developed for use in advanced microelectronics. Silver flake and micron-sized spherical silver powder were used as the conductive fillers with the binder system consisting of monofunctional liquid acrylate monomers. Because of the thermoplastic nature of the cured binder system,...
In the present studies, electroless ternary Ni-Co-P alloy deposits were prepared in an alkaline bath and characterizations were carried out to ascertain their properties such as composition, structure, phase transformation behavior and microhardness. The effect of various anions of the metallic sources was studied on the structure and properties of the ternary deposits. The different anionic bases...
In this study, cellulose acetate propionate (CAP) and polyvinylidene fluoride (PVDF) were selected to prepare porous-blend membrane by wet phase inversion method. The effect of the CAP and PVDF concentration of the casting solution on membrane morphology structure and thermal stability was investigated by scanning electron microscopy (SEM) and thermal gravimetry/differential scanning calorimetry (TGA/DSC)...
Suitable thermal treatments can be used to modify the microstructure of polymer electrets, which in turn may lead to better electret properties. In this paper, non-porous and porous PTFE films are subjected to a thermal treatment consisting of heating at 320°C for 2 min followed by quenching in liquid nitrogen. The influence of such a treatment on the charge stability of the film electrets is studied...
A kind of form-stable phase change material (PCM) based on capric-lauric acid eutectic acting as the heat-absorbing material and nano silicon dioxide serving as the supportive material was prepared by sol-gel method. The optimal proportion of the capric-lauric acid eutectic in the composite was determined as 60 wt.%. By the effect of capillarity and hydrogen bonding, fatty acid eutectic can be immobilized...
To explore the preparation method and characters of a new nanosized As2O3/Mn0.5Zn0.5Fe2O4 thermosensitive magnetoliposome and its antitumor effect on MDA_MB_231 cells. The nanosized As2O3/ Mn0.5Zn0.5Fe2O4 thermosensitive magnetoliposome was prepared by the method of rotatory film and high-pressure homogenization, and detected by TEM, SEM, EDS, atom fluorescence spectrophotometer spherical and DSC...
Fine and ultra-fine powders are actively studied in a broad and interdisciplinary area of nanotechnology. This paper presents the complex of well-grounded solutions for direct production of nanopowders by the exploding wire method. The influence of initial conditions on the properties of powders is discussed. The basic factors are as follows: the level and the uniformity of heating, the heating rate,...
