| 1 | Effect of Rare Earth and Transition Metal Elements on the Glass Forming Ability of Mechanical Alloyed Al–TM–RE Based Amorphous Alloys显示文摘The present work aims to compare the amorphous phase forming ability of ternary and quaternary Al based alloys(Al86Ni8Y6, Al86Ni6Y6Co2, Al86Ni8La6 and Al86Ni8Y4.5La1.5) synthesized via mechanical alloying by varying the composition, i.e. fully or partially replacing rare earth(RE) and transition metal(TM) elements based on similar atomic radii and coordination number. X-ray diffraction and high resolution transmission electron microscopy study revealed that the amorphization process occurred through formation of various intermetallic phases and nanocrystalline FCC Al. Fully amorphous phase was obtained for the alloys not containing lanthanum, whereas the other alloys containing La showed partial amorphization with reappearance of intermetallic phases attributed to mechanical crystallization. Differential scanning calorimetry study confirmed better thermal stability with wider transformation temperature for the alloys without La. | Ram S.Maurya Tapas Laha | 2015 | Journal of Materials Science & Technology2015，31，11： | 3 |
| 2 | Effect of sintering temperature on phase evolution of Al86Ni6Y4.5Co2La1.5 bulk amorphous composites synthesized via mechanical alloying and spark plasma sintering显示文摘Al86Ni6Y4.5Co2La1.5 amorphous powders were synthesized by mechanical alloying for 200 h. Subsequent consolidation was performed via spark plasma sintering in the temperature range of 250 ℃ to 500 ℃ at the pressure of 500 MPa. The role of viscous flow on densification was investigated by studying the viscosity change of the amorphous phase at different consolidation temperatures. The decrease in viscosity at higher sintering temperatures resulted in better particle bonding and densification of consolidated samples. The formation of only FCC Al was observed in the consolidated samples at sintering temperatures ≤ 300 ℃ and the intermetallic phases formed at temperatures ≥ 400 ℃. The mechanical properties of the bulk samples were measured by Vickers microhardness and nanoindentation tests. The testing results showed that the average values of microhardness, nanohardness and elastic modulus of the sample consolidated at 500 ℃ were 3.06 ± 0.14 GPa,4.85 ± 1.14 GPa and 89.53 ± 9.25 GPa, respectively. The increase in hardness and elastic modulus of the higher temperature consolidated samples is attributed to the improvement in particle bonding, densification and distribution of various hard intermetallic phases in the amorphous matrix. | Ashutosh Sahu Ram Sajeevan Maurya Tapas Laha | 2019 | Progress in Natural Science:Materials International2019，29，1： | 2 |

| 6 | Hydrogen sulfide intervention in cystathionine-β-synthase mutant mouse helps restore ocular homeostasis显示文摘AIM: To investigate the applications of hydrogen sulfide(H2 S) in eye-specific ailments in mice.METHODS: Heterozygous cystathionine-β-synthase(CBS+/-) and wild-type C57 BL/6 J(WT) mice fed with or without high methionine diet(HMD) were administered either phosphate buffered saline(PBS) or the slow-release H2 S donor: GYY4137. Several analyses were performed to study GYY4137 effects by examining retinal lysates for key protein expressions along with plasma glutamate and glutathione estimations. Intraocular pressure(IOP) was monitored during GYY4137 treatment; barium sulfate and bovine serum albumin conjugated fluorescein isothiocyanate(BSA-FITC) angiographies were performed for examining vasculature and its permeability post-treatment. Visionguided behavior was also tested employing novel object recognition test(NORT) and light-dark box test(LDBT) recordings.RESULTS: CBS deficiency(CBS+/-) coupled with HMD led disruption of methionine/homocysteine(Hcy) metabolism leading to hyperhomocysteinemia(HHcy) in CBS+/-mice as reflected by increased Hcy, and s-adenosylhomocysteine hydrolase(SAHH) levels. Unlike CBS, cystathionine-γ lyase(CSE), methylenetetrahydrofolate reductase(MTHFR) levels which were reduced but compensated by GYY4137intervention. Heightened oxidative and endoplasmic reticulum(ER) stress responses were mitigated by GYY4137 effects along with enhanced glutathione(GSH) levels. Increased glutamate levels in CBS+/-strain were prominent than WT mice and these mice also exhibited higher IOP that was lowered by GYY4137 treatment. CBS deficiency also resulted in vision-guided behavioral impairment as revealed by NORT and LDBT findings. Interestingly, GYY4137 was able to improve CBS+/-mice behavior together with lowering their glutamate levels. Blood-retinal barrier(BRB) appeared compromised in CBS+/-with vessels' leakage that was mitigated in GYY4137 treated group. This corroborated the results for occludin(an integral plasma membrane protein of the cellular tight junctions) stabilization.CONCLUSION: Findings reveal that HHcy-induced glutamate excitotoxicity, oxidative damage, ER-stress and vascular permeability alone or together can compromise ocular health and that GYY4137 could serve as a potential therapeutic agent for treating HHcy induced ocular disorders. | Akash K.George Rubens P.Homme Avisek Majumder Anwesha Laha Naira Metreveli Harpal S.SANDhu Suresh C.Tyagi Mahavir Singh | 2019 | International Journal of Ophthalmology(English edition)2019，12，5： | 2 |
