Enhanced performance of nano-sized SiC reinforced Al metal matrix nanocomposites synthesized through microwave sintering and hot extrusion techniques

引用

Progress in Natural Science:materials International 2017年第5期27卷 606-614页

作者： m.Penchal reddy R.A.Shakoor gururaj Parande Vyasaraj manakari F.Ubaid A.m.A.mohamed manoj gupta Center for Advanced materials Qatar University Department of mechanical Engineering National University of Singapore Department of metallurgical and materials Engineering Suez University

In the present study, nano-sized SiC(0, 0.3, 0.5, 1.0 and 1.5 vol%) reinforced aluminum(Al) metal matrix composites were fabricated by microwave sintering and hot extrusion techniques. The structural(XRD, SEm),mechanical(nanoindentation, compression, tensile) and thermal properties(co-efficient of thermal expansionCTE) of the developed Al-SiC nanocomposites were studied. The SEm/EDS mapping images show a homogeneous distribution of SiC nanoparticles into the Al matrix. A significant increase in the strength(compressive and tensile) of the Al-SiC nanocomposites with the addition of SiC content is observed. However,it is noticed that the ductility of Al-SiC nanocomposites decreases with increasing volume fraction of SiC. The thermal analysis indicates that CTE of Al-SiC nanocomposites decreases with the progressive addition of hard SiC nanoparticles. Overall, hot extruded Al 1.5 vol% SiC nanocomposites exhibited the best mechanical and thermal performance as compared to the other developed Al-SiC nanocomposites.

AIm To see how patterns of care changed over time,and how institution type effected these *** A retrospective analysis was performed using the National Cancer Database,looking at all patients that were diagnosed with rectal cancer from 1998 to 2011. We tested differences in rates of treatment and stage migration using χ~2 tests and logistic regression models. RESULTS A review of ninety thousand five hundred and ninety four subjects underwent multimodality therapy for cancer of the rectum. Staging and response to treatment varied greatly between centers. Forty-six percent of the time staging was missing in academic practices,vs fiftyfour percent of the time in community centers(P ged and eight percent up-staged in academia,whereas only fifteen percent were down-staged and 8% up-staged in community practices(P gery in *** two years this increased to fifty-three percent. This increased to eighty-six percent by 2011(P ment varied greatly. Fifty-one percent received therapy before surgery in academic centers in 1998. Thirty-nine percent followed this pattern in the same year in the community(P mic centers,vs eighty-four percent in the community(P mia,although an increase was seen in both center types. CONCLUSION From the study dates of 1998 to 2011,preoperative treatment with radiation has been on the rise. There is certainly an increased rate of use of radiation in academia,however,this trend is also seen in the community. Practice patterns have evolved over time,although rates of assigning clinical stage are grossly underreported prior to initiation of preoperative therapy.

Solid-liquid extraction of gd(Ⅲ) and separation possibilities of rare earths from phosphoric acid solutions using Tulsion CH-93 and Tulsion CH-90 resins

引用

Journal of Rare Earths 2012年第12期30卷 1270-1275页

作者： S.Radhika V.Nagaraju B.Nagaphani Kumar m.Lakshmi Kantam B.Ramachandra reddy Inorganic Chemistry Division Indian Institute of Chemical Technology(IICT) Rubamin Limited Halol-389 350India

Solid-liquid extraction of gadolinium was investigated from phosphoric acid medium using commercial amino phosphonic acid resin, Tulsion CH-93. The experimental conditions studied included equilibration time, acid concentration, mass of the resin, metal concentration, loading and elution. The percent extraction of gd（Ⅲ） was studied as a function of phosphoric acid （0.05-3 mol/L） using Tulsion CH-93 resin. The corresponding lgD vs. equilibrium pH plot gave straight line with a slope of 1.8. The percent extraction decreased with acid co centration increasing, conforming ion exchange mechanism. Under observed experimental conditions the loading capacity of Tulsion CH-93 for gadolinium was 10.6 mg/g. Among several eluants screened, the quantitative elution of gd（III） from loaded Tulsion CH-93 was obtained with ammonium oxalate （0.15 mol/L）. The extraction behavior of commonly associated metals with gadolinium was studied as a function of phosphoric acid concentration. Tulsion CH-93 resin showed selective extraction towards heavy rare earths （Lu and Yb） which could be separated from other rare earths at 3 mol/L H3PO4, similar to wet phosphoric acid （3-5 mol/L）. On the other hand gd（Ⅲ） and other rare earths were studied with chelating resin Tulsion CH-90. Light rare earths were highly extracted and these could be separated from heavy rare earths and gd.

Due to the characteristic emission of phosphors,phosphor-converted LEDs have been employed to provide the requisite light sources for indoor plant growth in the optical agricultural ***,we prepared a series of mn^(2+)co-doped NaSrB5 O9:Dy^(3+)phosphors via a solid-state reaction *** phosphors have significant three-band emissions at 467 nm(blue region),606 nm(orange region),and765 nm(far-red region),ascribed to the^(4)F_(9/2)-^(6)H_(15/2)and 4 F9/2-6 H13/2 transitions of the Dy^(3+)ions and the^(4)T_(1g)(g)-^(6)A_(1g)(S)spin-forbidden transition of the mn^(2+)ions,respectively,when excited by light of 376 nm(near-UV region).The co-dopant in the host material facilitates tunable photoluminescence(PL)due to energy transfer from the Dy^(3+)ions to the mn^(2+)*** three emission peaks from the prepared phosphors well match with the absorption spectra of the photosynthesis pigments of plants,chlorophyll and phytochrome,which can absorb blue(400-500 nm),orange-red(550-700 nm),and infrared(IR)radiation,indicating that these phosphors have potential applications in the fabrication of plant-growth *** to the PL studies,the structure of the phosphors was determined by X-ray diffraction,refined by Rietveld method and chemically quantified by X-ray photoelectron spectroscopy.
