在室温和高温下,以不同辐射剂量的H+、N+和Ar+离子辐照多壁碳纳米管和无定形碳纳米线。利用透射电镜和拉曼光谱研究多壁碳纳米管和无定形碳纳米线的结构变化及损伤。以70keV N+离子束辐射多壁碳纳米管在室温下可形成无定形碳纳米线。1000K下70keV的H+离子束照射导致无定形碳纳米线向金刚石结构转变。离子辐照多壁碳纳米管的有序程度足够高,70keV的N+和Ar+离子能够引起碳从多壁碳纳米管的剥落。离子辐射能够为缺陷的转化提供必需的动力学驱动力。

This paper presents a study on the Design of Experim.nts(Do E) approach to optim.ze the fabrication param.ters of titania(TiO2) em.edded glass fiber reinforced polyester hybrid com.osites(HCs). HCs of unsaturated polyester resin(UPR) were fabricated using m.thyl ethyl ketone peroxide(m.KP) as the curing agent by hand lay-up process(HLUP) and com.ression m.lding technique(Cm.). The fabrication param.ters were optim.zed by Taguchi Do E(an orthogonal array of L25) using 3 control factors(concentration of TiO2, concentration of m.KP and curing tem.erature) having 5 levels each. Statistical tools were em.loyed to identify significant factors affecting tensile strengths and its reproducibility during HLUP. It was found that the concentration of TiO2in HCs significantly influenced the tensile strength(TS) followed by m.KP concentration and curing tem.erature. The highest value of TS was obtained at 3 wt% TiO2, 2 wt% m.KP and 80 °C. Nevertheless, the sensitivity of TiO2concentration was basis for fabrication of polyester titania glass fiber hybrids(PTGFHs), which were further investigated for density and void fractions, linear shrinkage, flexural strength, im.act strength, hardness and therm.l behaviors. m.reover, cross-linking and hydrogen-bonding between polym.ric chains, styrene, silica content of glass fiber and TiO2particles in PTGFHs were confirm.d by Fourier transform.infrared spectroscopy.

Soil salinity affects the growth and yield of *** stress of soil salinity on plants can be m.tigated by inoculation of plant growth prom.ting bacteria(PGPR).The influence of PGPR inoculation on wheat(Triticum.aestivum.L.)crop productivity under salinity stress has not been properly addressed so ***,the present study was conducted to investigate the effects of various PGPR strains(W14,W10 and 6K;alone and com.ined)at several growth attributes of wheat plant under different soil salinity gradients(3,6 and 9 dS m.1).The growth attributes of wheat(height,roots,shoots,spikes,grains quality,biological and econom.cal yield,nutrients nitrogen,phosphorus and potassium.in grains)were highly affected by salinity and decreased with increasing salinity *** PGPR inoculation substantially prom.ted growth attributes of wheat and prom.nent results were observed in W14×W10×6K treatm.nt at all salinity *** results suggest that inoculation of PGPR is a potential strategy to m.tigate salinity stress for im.roving wheat growth and yield.

The m.ss concentrations of eighteen airborne sam.les collected from.Lahore (Pakistan) are found in the range from.595 to 3027μg/m.with average value of 1130 μg/m.. m.st of these values are norm.l and as reported in the literature for other parts of the world. The m.jor phases identified in the sam.les by the X-ray powder diffraction technique are Albite (Anorthite), Calcite, Clinochlore (Chlorite), Gypsum. Illite, Quartz and Talc which have also been reported by other researchers to be present in the airborne particulates of other world locations. The average weight percentages of the phases (m.nerals) in the sam.les are respectively 15.5, 10.6, 23.7, 2.4, 19.1, 20.2, and 8.5. Som. of the elem.nts (e.g., boron, cadm.um. lithium. m.nganese, titanium. and zinc) quantified in two sam.les determ.ned using a spark-source m.ss spectrom.ter appear also to derive their origin from.m.n-m.de activities. However no com.ound synthesized in the atm.sphere is detected by the X-ray diffraction m.thod.
