| 1 | Lanthanide doped fluorosilicate glass-ceramics:A review on experimental and theoretical progresses显示文摘Significant developments have been made in the past few decades for lanthanide(Ln)ions doped fluorosilicate glass-ceramics(Flusi-GCs).As novel generation of luminescence materials with a wide range of applications,Flusi-GCs as a single host combine the advantages of glass and ceramics/crystals as well as fluorides and silicates.In this review,the chemical design principles and experimental procedures of Flusi-GCs are summarized in detail.Flusi-GCs are categorized as those containing PbxCd_(1-x)F_(2),RF_(3)(R=Y,La,Gd),MF_(2)(M=Ca,Sr,Ba),xMF_(2)-yRF_(3)(R=Y,La-Lu),mAF-nRF_(3)(A=Li,Na,K),KTF_(3)(T=Zn,Mn)and K2 SiF6 nanocrystals(NCs).Theoretical breakthroughs mainly by molecular dynamic(MD)simulation have been recapitulated as efficient routes for composition-design,nano-crystallization-prediction,and performance-optimization of Flusi-GCs containing target fluoride NCs.Essential research progresses pertaining photonic applications have been made in random lasers,communication amplifiers,optical fibers,spectral converters,white light-emitting-diodes(WLEDs),and thermal sensors.In the end,we propose three future research directions for Flusi-GCs. | Pengcheng Li Xiuxia Xu Junjie Zhao Pragati Awasthi Xusheng Qiao Jincheng Du Xianping Fan Guodong Qian | 2022 | Journal of Rare Earths2022，40，2： | 2 |
| 2 | Strengths,weaknesses,opportunities,and threats(SWOT)analysis of supercapacitors:A review显示文摘The development of clean and sustainable energy sources has received widespread interest in the past few decades due to the rolling energy demands while extenuating the rising tiers of greenhouse gases and environmental pollution.Due to their intermittent nature,these green and sustainable sources require appropriate energy storage systems.Amongst different energy storage technologies,electrochemical energy storage devices,particularly supercapacitors(SCs),have fascinated global attention for their utilization in electric vehicles,power supports,portable electronics,and many others application requiring electric energy devices for their operation.Thus,the growth of SCs in the commercial market has squeezed requirements,and further developments are obligatory for their effective industrialization.In the meantime,SCs also face technical complications and contests for their introduction in industrial settings because of their low energy density and high Levelized cost.The present study combines core strengths,weaknesses,opportunities,and threats(SWOT)analysis of SCs with new perspectives and recent ideas.The challenges and the future progressive prospects of SCs are also presented in detail.This review will afford consistent direction and new superhighways for the further development of SCs as standalone and complementary energy storage systems. | Pragati A.Shinde Qaisar Abbas Nilesh R.Chodankar Katsuhiko Ariga Mohammad Ali Abdelkareem Abdul Ghani Olabi | 2023 | Journal of Energy Chemistry2023，，4： | 2 |

| 16 | Population and development:impacts on environmental performance显示文摘Population growth and development patterns have a significant impact on the environmental performance.The issue of concern is whether population growth or the consumption/production patterns are responsible for environmental deterioration.This paper is an attempt to capture the impact of technological development,affluence,and population on environmental performance index,while previous stuthes had captured the impact of these three factors on environment only through CO_2emissions.The analysis reveals that technological development and population size have a negative impact on environmental performance,whereas measures to improve affluence have a positive impact.Technological development has increased the production of energy efficient products but at the same time consumption of these products has increased manifold leading to environmental deterioration.Demographic attributes need specific attention to improve environmental performance.This paper concludes on some policy reflections on slowing the population growth as well as persuades individuals and economies to relook to their consumption and production patterns and channelize their efforts to protect the environment. | Prerna Jain Pragati Jain | 2016 | Chinese Journal of Population,Resources and Environment2016，16，3： | 1 |

| 18 | High energy superstable hybrid capacitor with a self-regulated Zn/electrolyte interface and 3D graphene-like carbon cathode显示文摘Rechargeable aqueous zinc ion hybrid capacitors(ZIHCs),as an up-and-comer aqueous electrochemical energy storage system,endure in their infancy because of the substandard reversibility of Zn anodes,structural deterioration of cathode materials,and narrow electrochemical stability window.Herein,a scalable approach is described that addresses Zn-anode/electrolyte interface and cathode materials associated deficiencies and boosts the electrochemical properties of ZIHCs.The Zn-anode/electrolyte interface is self-regulated by alteration of the traditional Zn2+electrolyte with Na-based supporting salt without surrendering the cost,safety,and green features of the Zn-based system which further validates the excellent reversibility over 1100 h with suppressed hydrogen evolution.The deficits of cathode materials were overcome by using a high-mass loaded,oxygen-rich,3D,multiscaled graphene-like carbon(3D MGC)cathode.Due to the multiscaled texture,high electronic conductivity,and oxygen-rich functional groups of 3D MGC,reversible redox capacitance was obtained with a traditional adsorption/desorption mechanism.Prototype ZIHCs containing the modified electrolyte and an oxygen-rich 3D MGC cathode resulted in battery-like specific energy(203 Wh kg1 at 1.6 A g^(-1))and supercapacitor-type power capability(4.9 kW kg1 at 8 A g^(-1))with outstanding cycling durability(96.75%retention over 30000 cycles at 10 A g^(-1)).These findings pave the way toward the utilization of highly efficient ZIHCs for practical applications. | Nilesh R.Chodankar Swati J.Patil Sangjin Lee Jaeho Lee Seung-Kyu Hwang Pragati A.Shinde Indrajit V.Bagal Smita V.Karekar Ganji Seeta Rama Raju Kugalur Shanmugam Ranjith Deepak P.Dubal Yun-Suk Huh Young-Kyu Han | 2022 | InfoMat2022，4，10： | 0 |
| 19 | Variations of the harmonic components of the X-ray pulse profile of PSR B1509–58显示文摘We used the Fourier decomposition technique to investigate the stability of the X-ray pulse profile of a young pulsar PSR B1509–58 by studying the relative amplitudes and phase differences of its harmonic components with respect to the fundamental using data from the Rossi X-Ray Timing Explorer. Like most young rotation powered pulsars, PSR B1509–58 has a high spin down rate. It also has less timing noise, allowing accurate measurement of higher order frequency derivatives which in turn helps in the study of the physics of pulsar spin down. Detailed investigation of pulse profiles over the years will help us establish any possible connection between the timing characteristics and the high energy emission characteristics for this pulsar.Furthermore, the study of pulse profiles of short period X-ray pulsars can also be useful when used as a means of interplanetary navigation. The X-ray pulse profile of this source has been analyzed for 15 yr(1996–2011). The long term average amplitudes of the first, second and third harmonics(and their standard deviation for individual measurements) compared to the fundamental are 36.9%(1.7%), 13.4%(1.9%) and 9.4%(1.8%) respectively. Similarly, the phases of the three harmonics(and standard deviations) with respect to the fundamental are 0.36(0.06), 1.5(0.2) and 2.5(0.3) radian respectively. We do not find any significant variation of the harmonic components of the pulse profile in comparison to the fundamental. | Pragati Pradhan Biswajit Paul Harsha Raichur Bikash Chandra Paul | 2015 | Research in Astronomy and Astrophysics2015，15，1： | 0 |
| 20 | A report on TypeⅡX-ray bursts from SMC X-1显示文摘We study RXTE PCA data for the high mass X-ray binary source SMC X-1 between 2003–10 and 2003–12 when the source was in its high states.The source is found to be frequently bursting which can be seen as flares in lightcurves that occur at a rate of one every 800 s, with an average of 4–5 Type Ⅱ X-ray bursts per hour.We note that typically a burst was short, lasting for a few tens of seconds in addition to a few long bursts spanning more than a hundred seconds that were also observed.The flares apparently occupied 2.5% of the total observing time of 225.5 ks.We note a total of 272 flares with mean FWHM of the flare ~21 s.The rms variability and aperiodic variability are independent of flares.As observed, the pulse profiles of the lightcurves do not change their shape, implying that there is no change in the geometry of an accretion disk due to a burst.The hardness ratio and rms variability of lightcurves exhibit no correlation with the flares.The flare fraction shows a positive correlation with the peak-to-peak ratio of the primary and secondary peaks of the pulse profile.The observed hardening or softening of the spectrum cannot be correlated with the flaring rate but may be due to the interstellar absorption of X-rays as evident from the change in hydrogen column density(n_H).It is found that the luminosity of the source increases with the flaring rate.Considering that the viscous timescale is equal to the mean recurrence time of flares, we fixed the viscosity parameter α~ 0.16. | Binay Rai Pragati Pradhan Bikash Chandra Paul | 2018 | Research in Astronomy and Astrophysics2018，18，12： | 0 |
