1Variation in Polyphenolics and Antioxidant Activity of Traditional Apple Cultivars from West Himalaya,Uttarakhand显示文摘Apple(Malus × domestica) is largely known for polyphenolic and antioxidant properties; however, systematic investigation in the apple growing in the Indian Himalayan region is not carried out. The present study therefore, attempts to quantify polyphenolics and antioxidant activities in three traditional apple cultivars namely 'Benoni', 'Fanny' and 'Rymer' growing at different locations of Uttarakhand(west Himalaya), India.Results revealed that phenolic(0.94–7.00 mg GAE·g^(-1)FW), flavonoid(1.02–9.86 mg QE·g^(-1)FW), flavonol(0.77–6.92 mg CE·g^(-1) FW), tannin(15.49–37.99 mg TAE·g^(-1) FW) and antioxidant activity(ABTS, 3.10–67.36; DPPH, 4.99–14.06; FRAP, 4.70–39.21 mmol AAE·kg^(-1)FW) varied significantly among the cultivars and maximum content was recorded in Rymer fruits of Mukhwa location. Altitude showed significant(P < 0.05) positive relationship with total phenolic(r = 0.895), flavonoid(r = 0.843), flavonol(r = 0.812), ABTS(r = 0.856) and FRAP activity(r = 0.830). Based on the results, it is concluded that among three cultivars, Rymer is one of the most promising sources of polyphenolic content and antioxidant activity and therefore, recommended for mass plantation at suitable locations in Uttarakhand for harnessing maximum potential.BAHUKHANDI Amit DHYANI Praveen BHATT Indra D.

2Integrated Bi2O3 nanostructure modified with Au nanoparticles for enhanced photocatalytic activity under visible light irradiation显示文摘An integrated Bi_2O_3(i-Bi_2O_3) nanostructure with a particle size 10 nm inducing agglomerated structure were synthesized by dissolving bismuth nitrate pentahydrate in diethylene glycol at 180 ℃ with post heat treatment.The prepared i-Bi_2O_3 nanostructures were employed for the construction of Au/i-Bi_2O_3 composite system and characterized by X-ray diffraction pattern,UV-visible diffuse reflectance spectroscopy(DRS),and transmission electron microscopy,X-ray photoemission spectroscopy(XPS) and Energy dispersive X-ray spectroscopy(EDS).The i-Bi_2O_3 nanostructure and Au/i-Bi_2O_3 composite system were found to exhibit high photocatalytic activity than commercial Bi_2O_3 in decomposing salicylic acid under visible light irradiation.The high catalytic activity of i-Bi_2O_3 nanostructure was deduced to be caused by charge separation facilitated by electron hopping between the particles within the integrated structure and space-charge separation between i-Bi_2O_3 and Au.The charge separation behavior in i-Bi_2O_3 nanostructure was further bolstered by comparing the measured.OH radical produced in the solution with i-Bi_2O_3 nanostructure,commercial Bi_2O_3 and Au/i-Bi_2O_3 composite which readily react with 1,4-terephthalic acid(TA) inducing 2-hydroxy terephthalic acid(TAOH) that shows unique fluorescence peak at 426 nm.The space-charge separation between i-Bi_2O_3 and An was confirmed by measuring the electron spin resonance(ESR) spectra.Hankwon Lim Sher Bahadur Rawal 2017Progress in Natural Science:Materials International2017,27,3:5

6Feeding Biochar to Cows:An Innovative Solution for Improving Soil Fertility and Farm Productivity显示文摘Addition of biochar produced through thermal decomposition of biomass has been seen as a strategy to improve soils and to sequester carbon(C), but wide scale implementation of the technology requires to devise innovative profitable solutions. To develop biochar utilisation with an integrated system approach, an innovative program was implemented in 2012 on a 53-ha farm in Western Australia to determine the costs and benefits of integrating biochar with animal husbandry and improvement of pastures. Biochar was mixed with molasses and fed directly to cows. The dung-biochar mixture was incorporated into the soil profile by dung beetles.We studied the changes in soil properties over 3 years. Biochar extracted from fresh dung and from the soil to a depth of 40 cm was characterised. A preliminary financial analysis of the costs and benefits of this integrated approach was also undertaken. The preliminary investigation results suggested that this strategy was effective in improving soil properties and increasing returns to the farmer. It was also concluded that the biochar adsorbed nutrients from the cow's gut and from the dung. Dung beetles could transport this nutrient-rich biochar into the soil profile. There was little evidence that the recalcitrant component of the biochar was reduced through reactions inside the gut or on/in the soil. Further research is required to quantify the long-term impact of integrating biochar and dung beetles into the rearing of cows.Stephen JOSEPH Doug POW Kathy DAWSON David R.G.MITCHELL Aditya RAWAL James HOOK Sarasadat TAHERYMOOSAVI Lukas VAN ZWIETEN Joshua RUST Scott DONNE Paul MUNROE Ben PACE Ellen GRABER Torsten THOMAS Shaun NIELSEN Jun YE Yun LIN PAN Genxing LI Lianqing Zakaria M.SOLAIMAN 2015Pedosphere2015,25,5:2

8High population and dispersion of pentacoordinated Al~Ⅴ species on the surface of ?ame-made amorphous silica-alumina显示文摘Pentacoordinated Al(Al~Ⅴ)species in silica-alumina are promising to promote the formation of acid sites or act as surface defects for tailoring single-atom catalysts.However,pentahedral coordination(Al~Ⅴ)is rarely observed in conventionally prepared silica-alumina.Here,we show that high population and dispersion of Al~Ⅴ species on the surface of amorphous silica-alumina(ASA)can be achieved by means of flame spray pyrolysis.High resolution TEM/EDX,high magnetic-field NMR and DFT calculations are employed to characterize the structure of as-prepared ASAs.Solid-state ^(27)Al multi-quantum MAS NMR experiments show that most of the Al~Ⅴspecies are formed independently from the alumina phase and are accessible for guest molecules on the surface.Upon water adsorption,these Al~Ⅴ species are transformed to Al~Ⅵ species,structurally similar to surface Al~Ⅳ species,as confirmed by DFT calculations.The outstanding catalytic activity of as-synthesized ASA is demonstrated using the in situ H/D exchange reaction with deuterated benzene as an example.The Al~Ⅴ-rich ASA provides a much lower activation energy(~30 kJ/mol)than that reported for zeolite H-ZSM-5(~60 kJ/mol).The superior catalytic performance is attributed to the high Al~Ⅴcontent promoting the surface active sites in ASA.The knowledge gained on the synthesis of Al~Ⅴ-rich ASAs and the nature of aluminum coordination in these materials could pave the way to more efficient silica-alumina based catalysts.Zichun Wang Yijiao Jiang Xianfeng Yi Cuifeng Zhou Aditya Rawal James Hook Zongwen Liu Feng Deng Anmin Zheng Michael Hunger Alfons Baiker Jun Huang 2019Science Bulletin2019,64,8:2
9Prospects for 3D bioprinting of organoids显示文摘Three-dimensional(3D)organoids derived from pluripotent or adult tissue stem cells seem to possess excellent potential for studying development and disease mechanisms alongside having a myriad of applications in regenerative therapies.However,lack of precise architectures and large-scale tissue sizes are some of the key limitations of current organoid technologies.3D bioprinting of organoids has recently emerged to address some of these impediments.In this review,we discuss 3D bioprinting with respect to the use of bioinks and bioprinting methods and highlight recent studies that have shown success in bioprinting of stem cells and organoids.We also summarize the use of several vascularization strategies for the bioprinted organoids,that are critical for a complex tissue organization.To fully realize the translational applications of organoids in disease modeling and regenerative medicine,these areas in 3D bioprinting need to be appropriately harnessed and channelized.Preety Rawal Dinesh M.Tripathi Seeram Ramakrishna Savneet Kaur 2021Bio-Design and Manufacturing2021,4,3:2

11Infertility Management in Men with Cystic Fibrosis显示文摘Cystic fibrosis (CF) is a multisystem autosomal recessive disorder. CF has a reported incidence of 1 in 2 500 and a carrier frequency of 1 in 25. It is caused by mutations in a gene located on the long arm of chromosome 7. With almost 50% of patients with CF now in the adult population, and a very high interest in future parenting (78% of men wanting children), there is an increasing need to be proactive in terms of advice about reproductive health. Discussion on reproduction should start in early adolescence and be regularly updated by medical staff. The recent advances in reproductive techniques have allowed the development of sperm aspiration coupled with intra-cytoplasmic sperm injection (ICSI). Spermatozoa can be retrieved from either the epididymis or the testes. Genetic counselling is strongly recommended for both partners when congenital bilateral aplasia of vas deferens (CBAVD) is diagnosed as there is the inevitability of transmitting a mutated CFTR gene, and an increased risk of producing an affected child with serious long-term implications. Most treatment centres, with the introduction of ICSI, routinely screen all males with azoospermia caused by obstruction (other than that caused by vasectomy) or germ cell failure. Protocols usually involve screening for 28 relatively common CFTR mutations. Further advanced testing may be necessary up to a final detection level of approximately 98.5%. Before considering any assisted reproduction treatment, it is pertinent that CF patients receive medical and psychological counselling.Nikita Rawal Rafit Gazvani Roger Mountford 2009Journal of Reproduction and Contraception2009,20,1:2
12Structural,Wettability and Optical Investigation of Titanium Oxynitride Coatings:Effect of Various Sputtering Parameters显示文摘The objective of the present work is to investigate the effect of various sputtering parameters such as nitrogen flow rate,deposition time and sputtering pressure on structural,wettability and optical properties of titanium oxynitride films deposited on glass substrate by reactive magnetron sputtering.The X-ray diffraction graphs of titanium oxynitride films show evolution of various textures of TiO_xN_y and TiN phases with increasing nitrogen flow rate and deposition time,but an increase in sputtering pressure from 4.0 to 8.0 Pa results in decline of various textures observed for TiO_xN_y and TiN phases.The stress and strain calculated by sin^2Ψ method are compressive,which decrease with increasing nitrogen flow rate from 55 to 100 sccm(standard cubic centimeter per minute) and increase with increasing deposition time from 80 to 140 min due to atomic penning effect and increasing thickness of the deposited films.The titanium oxynitride films have contact angle values above 90 deg.,indicating that films are hydrophobic.The maximum contact angle of 109.1 deg.is observed at deposition time of 140 min.This water repellent property can add value to potential protective,wear and corrosion resistant application of titanium oxynitride films.The band gap decreases from 1.98 to 1.83 eV as nitrogen flow rate is increased from 55 to 100 sccm;it decreases from 1.93 to 1.79 eV as deposition time is increased from 80 to 140 min as more nitrogen incorporation results in higher negative potential of valence band N2p orbital.But it increases from 2.26 to 2.34 eV for titanium oxynitride films as sputtering pressure increases from 4.0 to 8.0 Pa.Sushant K Rawal Amit Kumar Chawla R.Jayaganthan Ramesh Chandra 2012Journal of Materials Science & Technology2012,28,6:2
