The effect of four different compounds as the combustion stabilizers of composite solid propellants based on the AP/HTPB/IPDI has been presented in this paper. Except that, various total solid content, ammonium-perchlorate bimodal and trimodal combination of particle sizes ratio have been made by preparing the eleven…
OBJECTIVE: In this study, we have detected the expression of STC2 protein in laryngeal cancer and The safe incisal margin by immunohistochemical staining, to evaluate its correlation with clinical features and the prognosis value in laryngeal squamous cell cancer. METHOD: Eighty-one paraffin-embedd specimens of patien…
Carbohydrate-conjugated fluorescent silica nanoprobes were prepared and used as a platform for galectin-1 and prostate cancer cell detection. The nanoparticles were efficiently conjugated using native, unprotected carbohydrate structures following a photochemical approach, resulting in lactose- and cellobiose-conjugat…
A model-based approach for the design and development of electrically heated catalyst (EHC) systems is presented. Based on experimental analysis of the EHC heat-up and catalytic behaviour, a detailed physico-chemical EHC model is developed. Within a total system simulation environment, different heat-up measures are c…
In the current study, a review on the response of soils subjected to high strain rate loadingis presented. High strain rate loading on soil may be applied through high loading rate uniaxialcompression tests, triaxial tests, split Hopkinson pressure bar (SHPB) tests, and shock tube test.Herein, the results of SHPB test…
Nanotechnology, which has become an important area of science, has caused an enormous developmental revolution in many fields. In the last two decades researchers have focused on overcoming the obstacles encountered during the preparation of nanoparticles. This article highlights the nanotechnology, along with a brief…
Microbial-induced mineralization technique can be used to repair the concrete surface defects and cracks. Recent development on the repair mechanisms, passive repair and self-healing was reviewed. The advantages of passive repair or active self-healing were analyzed. Some problems and the corresponding solutions were…
During the coal pulverizing, the working parts of the ventilation mill are being worn by the sand particles. For this reason, the working parts are usually protected with materials resistant to wear (hardfaced/thermal sprayed coatings). The aim of this study was to evaluate the tribological performance of four differe…
Carbon-incorporated Mn doped TiO 2 (C/Mn-TiO 2 ) microspheres with different Mn contents were prepared by a facile and novel flame assisted approach.The influence of the Mn contents on the morphology and performance was investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), ultr…
In order to improve the electrical tree resistance of polypropylene(PP),montmorillonite(MMT)/PP composites were prepared by one-step and two-step melting intercalation processes,in which the organic MMT as the nanophase and the maleic anhydride grafted polypropylene(PP-g-MAH)as the compatibilizer.The crystallization m…
Tresyl chloride (2,2,2-trifluoroethanesulfonyl chloride)-activated method is an easy and simple method for immobilizing biological molecules onto a titanium surface. Tresyl chloride was directly dropped onto a titanium surface without any solvent. Tresylated titanium disks were immersed in a protein or peptide solutio…
The effects of two different porous superfine powder materials( rice husk ash and acid leaching residue of boron mud) on the properties of Ultra High Performance Concrete( UHPC),such as slump flow,setting time,compressive strength,autogenous and drying shrinkage were studied in this paper.The results indicated that as…
With the deterioration of electromagnetic environment,it is quite urgent to explore a range of effective electromagnetic shielding materials in the field of material development.In this paper,the mechanism and normal measurements were simply introduced,and according to classification of metal and conducting polymer ma…
The absorption mechanism and classification of absorbing materials are introduced. The recent research progress and absorbing properties of microwave absorbing material, such as magnetic metal powders, ferrite materials, ceramics materials, nanomaterials, chiralmaterials and conductive polymer materials are summarized…
Fatigue fracture properties of wood plastic composites (WPC) were investigated. The material was based on a wood flour/ polypropylene (PP) master batch, and prepared to be 30wt％ and 50wt％ wood flour contents by the addition of PP pellets. First, kneading temperature and screw speed of a uni‐axial extruder were changed…
After many years of pre-eminence, titanium-based Ziegler–Natta catalysts and their derivatives have generated outstanding scientific breakthroughs and commercial successes in the synthesis of “petropolymers”. Nowadays, the need for greener polymers that are biodegradable and/or obtained from bioderived monomers receiv…
Hybrid materials based on organic polymers and Co II tetrasulfophthalocyanines are obtained. Polymer matrix was previously activated before macrocycle anchoring. Activation was carried out by microwaves and plasma-chemical treatment of polymer surface. The influence of polymer surface pretreatment on the degree of mac…
Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
Titanium oxide thin films were prepared by a pulsed laser deposition method using Ti and TiO2 powder and bulk targets. The deposition rate when using a powder target was higher than that in the case of a bulk target. These results may be caused as follows. The heat absorptivity of a powder target for the 532 nm laser…
During tempering process of steel materials, a plastic strain occurs along loading direction even if the macro-scopic stress is less than yield stress. The authors name this phenomenon “tempering plasticity”. The tempering plasticity may occur by not only external force but also residual stress. It can be expected, th…
