We describe the synthesis and properties of a novel silver complex of an adenine derivative bearing a sulfonate group. Adenine and sulfonate coordination with silver ions eventually leads to the formation of entangled networks with an embedded catenated framework and double helical assemblies.
Nanocomposites of silicon nanoparticles (Si NPs) dispersed in between graphene layers emerge as potential anode materials of high‐charge capacity for lithium‐ion batteries. A key design requirement is to keep Si NPs dispersed without aggregation. Experimental design of the Si NP dispersion in graphene layers has remai…
The aim of this investigation was to develop a novel multifunctional co-processed diluent consisting of microcrystalline cellulose (Avicel PH 102), crospovidone (Polyplasdone XL) and polyethylene glycol 4000. Colloidal silicon dioxide and talc were also incorporated as minor components in the diluent to improve tablet…
The physical and thermodynamic properties of a repulsive clathrate used as a working body for the dissipation, storage, and conversion of energy in thermomechanical systems are studied. In repulsive clathrates, use is made for the first time of the molecular repulsive forces acting in large interfacial areas in a syst…
The fractal tree-shaped structure such as tree, plant root, leaves, animal lung and so on is universal and unique in nature. These structures possess the symmetric micro-channel distributions and the efficient transport characteristics. They are considered to be an optimal network channel of mass transfer and heat tra…
The catalytic action of nano–sized Au particles supported on hematite (Fe2O3) and magnetite (Fe3O4) is compared in the continuous gas phase hydrogenation of p–chloronitrobenzene and m–dinitrobenzene. The catalysts were prepared by deposition–precipitation and have been characterised in terms of BET/pore volume, powder…
We report for the first time the combustion synthesis of flower-like ZnO–SnO2 composite microspheres by decomposition at temperatures of 873 K in the presence of polyethylene glycol as the surfactant. A plausible mechanism for the formation of the core-shell structured microspheres is also proposed. The as-obtained sa…
In this paper, we propose three Deflection-Routing-based Multicast (DRM) schemes for a bufferless NoC. The DRM scheme without packets replication (DRM_noPR) sends multicast packet through a non-deterministic path. The DRM schemes with adaptive packets replication (DRM_PR_src and DRM_PR_all) replicate multicast packets…
The use of a coarse limestone powder (median particle size of approximately 70 μm, five times larger than cement particles) as a cement replacement material results in a dilution effect. The magnitude of strength and transport property reduction is found to be greater than the magnitude of the cement replacement level…
Silver (Ag) possesses a well-known antibacterial activity and has been used for medical treatment and cosmetics such as wound dressing and deodorant powders. Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration (MSHA) proposed that the permissible exposure limit (PEL) for both…
In this work we have developed a simple and robust method to permanently pattern alternating hydrophobic and hydrophilic surfaces in off-stoichiometry thiol-ene (OSTE) polymer microchannels. By being able to tune the number of unreacted thiol surface groups of the OSTE Thiol polymers and by taking advantage of spatial…
AIM: To evaluate the possibility of generation 4 polyamidoamine (G4PAMAM) dendrimers acting as the delivery system of vascular endothelial growth factor (VEGF) antisense oligodeoxynucleotides (VEGFASODN), and to investigate the anti-tumor effect of G4PAMAM/VEGFASODN complex on the cultured cells and the mouse tumor xe…
In order to meet the steadily increasing worldwide energy demand, nuclear power is expected to continue playing a key role in electricity production. Currently, the large majority of nuclear power plants are operated with thermal-neutron spectra and need regular fuel loading of enriched uranium. According to the ident…
Cellulose, in combination with lignin and hemicellulose, is found in all plant materials. It is also the most abundant form of plant biomass. In the oil palm industry, empty fruit bunches (EFB), which are generated in large amounts at the palm oil mill, is made up of approximately 37% a-cellulose (on a dry weight basi…
Because of its high gas velocity and heat input,plasma arc welding(PAW) can penetrate thicker workpieces with a single pass because PAW can operate in the keyhole mode. Compared with electron beam and laser beam welding,keyhole PAW is more cost effective and more tolerant of joint preparation,so that it is widely used…
采用滴涂法和电沉积法制备了石墨烯/铁氰化钴复合膜修饰玻碳电极. 用扫描电镜对该纳米复合膜进行了表征.用循环伏安法研究了对苯二酚(HQ)、邻苯二酚(CT)和间苯二酚(RS)在修饰电极上的电化学行为. 实验结果表明, 相对于裸玻碳电极和石墨烯修饰电极, HQ, CT 和RS 在石墨烯/铁氰化钴修饰电极上的氧化峰电流显著提高. 利用差分脉冲伏安法测定, HQ, CT 和RS 分别在1.0×10－6～1.5×10－4 mol/L, 1.0×10－6～2.0×10－4 mol/L 和3.5×10－6～2.5×10－4 mol/L浓度范围内与氧化峰电流呈良好的线性关系, 相关系数分别为0.991, 0.993 和0.992. 信噪比为3 时,…
Spherical [Ni 0.5 Mn 0.3 Co 0.2 ](OH) 2 precursor with narrow size distribution and high tap density has been successfully synthesized by a continuous hydroxide coprecipitation, and Li[Ni 0.5 Mn 0.3 Co 0.2 ]O 2 is then prepared by mixing the precursor with 6% excess Li 2 CO 3 followed by calcinations. The tap density…
To determine the change in the ripening stage and quality through associated variables such as firmness and peel color is a useful tool for predicting the behavior and involvement of the product stored at different changing conditions. The change in O2 and CO2 concentration, pulp firmness and peel color were measured…
In this paper, Taguchi techniques are applied to find out the optimum tool flank wear width in turning operation of AISI 1045 Steel. A L9 orthogonal array, S/N ratios and ANOVA are used to study the performance characteristics of cutting speed, feed rate and depth of cut as turning parameters with tool flank wear widt…
The study was carried out to screen antimicrobial activity for a new natural,nontoxic and effective antibiotic from plant extract. In this study, Swietenia Macrophylla King was selected and antibacterial activity of extracts from different parts (leaf, fruit cover, seed cover) with various solvents or different fracti…
