Micro-scratching behavior of heat-treated cutting chips of Inconel 718
No full textThe present work investigates the micro-scratching behavior of Inconel 718 alloy processed by machining and subsequent heat-treatment. As-machined chips were heat-treated at 700 °C, 800 °C, and 900 °C, all for a short duration of 15 min, followed by water quenching to allow the precipitation of γ
I and γ
II phases. Microstructural analysis of the processed Inconel 718 chips revealed the formation of nano-size precipitates either along the grain boundaries or at the triple junctions, which contributed to the improved mechanical property compared to the solution annealed sample. It was found that the chips heat-treated at 700 °C possessed the highest average hardness (548 Kgf/mm
2) among all the sample conditions. High hardness of as-machined chips and short heat-treatment at 700 °C led bimodal microstructure and precipitation pining resulting in maximum wear resistance compared to other heat-treatment conditions. Subsequently, to verify the outcome, worn surface analysis of as-machined and subsequently heat-treated chips was performed. Comparatively, larger size cracks in sample heat-treated at 900 °C attributed to a high cracking scratch zone in the processed material, i.e., less wear resistance, whereas no/nominal crack in as-machined chips and chips heat-treated at 700 °C attributed to no cracking scratch zone.

The generation of dual wavelength pulse fiber laser using fiber bragg grating
Get PDFA stable simple generation of dual wavelength pulse fiber laser on experimental method is proposed and demonstrated by using Figure eight circuit diagram. The generation of dual wavelength pulse fiber laser was proposed using fiber Bragg gratings (FBGs) with two different central wavelengths which are 1550 nm and 1560 nm. At 600 mA (27.78 dBm) of laser diode, the stability of dual wavelength pulse fiber laser appears on 1550 nm and 1560 nm with the respective peak powers of -54.03 dBm and -58.00 dBm. The wavelength spacing of the spectrum is about 10 nm while the signal noise to ratio (SNR) for both peaks are about 8.23 dBm and 9.67 dBm. In addition, the repetition rate is 2.878 MHz with corresponding pulse spacing of about 0.5 μs, is recorded
Comparative genomic analysis reveals evolutionary and structural attributes of MCM gene family in Arabidopsis thaliana and Oryza sativa
No full textThe mini-chromosome maintenance (MCM) family, a large and functionally diverse protein family belonging to the AAA+ superfamily, is essential for DNA replication in all eukaryotic organisms. The MCM 2-7 form a heterohexameric complex which serves as licensing factor necessary to ensure the proper genomic DNA replication during the S phase of cell cycle. MCM 8-10 are also associated with the DNA replication process though their roles are particularly unclear. In this study, we report an extensive in silico analysis of MCM gene family (MCM 2-10) in Arabidopsis and rice. Comparative analysis of genomic distribution across eukaryotes revealed conservationof core MCMs 2-7 while MCMs 8-10 are absent in some taxa. Domain architecture analysis underlined MCM 2-10 subfamily specific features. Phylogenetic analyses clustered MCMs into 9 clades as per their subfamily. Duplication events are prominent in plant MCM family, however no duplications are observed in Arabidopsis and rice MCMs. Synteny analysis among Arabidopsis thaliana, Oryza sativa, Glycine max and Zea mays MCMs demonstrated orthologous relationships and duplication events. Further, estimation of synonymous and nonsynonymous
substitution rates illustrated evolution of MCM family under strong constraints. Expression profiling using available microarray data and qRT-PCR revealed differential expression under various stress conditions, hinting at their potential use to develop stress resilient crops. Homology modeling of Arabidopsis and rice MCM 2-7 and detailed comparison with yeast MCMs identified conservation of eukaryotic specific insertions and extensions as compared to archeal MCMs. Protein-protein interaction analysis revealed an extensive network of putative interacting partners mainly involved in DNA replication and repair. The present study provides novel insights into the MCM family in Arabidopsis and rice and identifies unique features, thus opening new perspectives for further targeted analyses

Distinct intramolecular hydrogen bonding dictates antimicrobial action of membrane-targeting amphiphiles
No full textAs mechanisms underpinning the molecular interactions between membrane-targeting antimicrobials and Gram-negative bacterial membranes at atomistic scale remain elusive, we used cholic acid (CA)-derived amphiphiles with different hydrophobicities as model antimicrobials and assessed the effect of their conformational flexibility on antimicrobial activity. Relative to other hydrophobic counterparts, a compound with a hexyl chain (6) showed the strongest binding with the lipopolysaccharide (LPS) of Gram-negative bacterial membranes and acted as an effective antimicrobial. Biomolecular simulations, validated by complementary approaches, revealed that specific intramolecular hydrogen bonding imparts conformationally rigid character to compound 6. This conformational stability of compound 6 allows minimum but specific interactions of the amphiphile with LPS that are a sum of exothermic processes like electrostatic interactions, membrane insertion, and endothermic contributions from disaggregation of LPS. Therefore, our study reveals that a membrane-targeting mechanism with the help of conformationally selective molecules offers a roadmap for developing future therapeutics against bacterial infections.</p
Ultra-light nanocomposite aerogels of bacterial cellulose and reduced graphene oxide for specific absorption and separation of organic liquids
No full textNovel materials based on sustainable materials with high absorption capacity are still rare for the separation of organic liquids or oil spills and water. In this report, ultra-light nanocomposite aerogels consisting of sustainable bacterial cellulose (BC) and graphene oxide (GO) were constructed after an eco-friendly freeze-drying process for the first time. Due to the hydrophilic properties of both materials and the highly porous structure, BC/GO aerogels could highly absorb not only organic liquids, such as cyclohexane and DMF, but also water. Specific absorption for organic liquids was achieved after the reduction of GO using H-2 gas, which led to nanocomposite aerogels of BC and reduced GO. They could specifically absorb 135-150 g organic liquids per g of their own weight, even with a high content of 80 BC in the nanocomposite aerogel
