Sur Koyel,Verma Vipan Kumar,Pateriya Brijendra 대한공간정보학회 2021 Spatial Information Research Vol.29 No.6

Nitrogen dioxide (NO2) is a gaseous air pollutant which primarily gets in the air when fossil fuels such as coal, oil, gas or diesel are burned at high temperatures through industries, power plant, automobiles and locomotive. Continuous exposure to elevated concentration of NO2 may impose development of asthma and potentially increase in susceptibility to respiratory infections in humans. The present study examined impact of lockdown due to COVID-19 in terms of spatial and temporal variation of tropospheric NO2 in Indo-Gangetic plain. The results showed steep reduction in tropospheric NO2 as a result of ceased industrial and economic activities. Analysis of Sentinel-5P satellite data was carried out for specific period during 2019–2020 at a regional scale and for major industrial cities. Tremendous positive impact of lockdown in atmospheric condition is observed, wherein NO2 concentration has gone down by 20–40% in all major cities except few exceptions were noticed. The concomitant impact of Covid-19 has ensued pragmatic constructive impact on environment and climate, due to drop in NO2 emissions.

Surface-enhanced Raman scattering (SERS) spectroscopy: a versatile spectroscopic and analytical technique used in nanoscience and nanotechnology

Sur, Ujjal Kumar Techno-Press 2013 Advances in nano research Vol.1 No.2

Surface-enhanced Raman scattering (SERS) effect deals with the enhancement of the Raman scattering intensity by molecules in the presence of a nanostructured metallic surface. The first observation of surface-enhanced Raman spectra was in 1974, when Fleischmann and his group at the University of Southampton, reported the first high-quality Raman spectra of monolayer-adsorbed pyridine on an electrochemically roughened Ag electrode surface. Over the last thirty years, it has developed into a versatile spectroscopic and analytical technique due to the rapid and explosive progress of nanoscience and nanotechnology. This review article describes the recent development in field of surface-enhanced Raman scattering research, especially fabrication of various SERS active substrates, mechanism of SERS effect and its various applications in both surface sciences and analytical sciences.

AN INTEGRAL EQUATION FOR KINKED CRACKS APPLIED TO MODE Ⅲ IN FINITE PLANE BODIES

Sur, Ukhwan 한국산업정보응용수학회 1998 한국산업정보응용수학회 Vol.2 No.1

An integral equation representation of cracks was presented, which differs from well-known "dislocation layer" representation. In this new representation, an integral equation representation of cracks was developed and coupled to the direct boundary-element method for treatment of cracks in plane finite bodies. The method was developed for in-plane( modes I and 11) loadings only. In this paper, the method is formulated and applied to mode I11 problems involving smooth or kinked cracks in finite region. 'The results are compared to exact solutions where available and the method is shown to be very accurate despite of its simplicity.

Biological green synthesis of gold and silver nanoparticles

Sur, Ujjal Kumar Techno-Press 2014 Advances in nano research Vol.2 No.3

Nanomaterials synthesized by natural bioresources such as microorganisms, animals and plants in nature can also be synthesized in laboratories even on large scale. This is considered as an attractive prospect for eco-friendly or so-called green synthesis. Development of eco-friendly synthesis of biocompatible nanoparticles and their potential biomedical applications introduces the concept of nanobiotechnology. The lower cost and lesser side effects as compare to chemical methods of synthesis are the main advantages of biosynthesis. This review article demonstrates the role of various biological resources e.g. bacteria, fungi, actinomycetes, plant leaves, fruits and honey as well as animal tissues for the synthesis of nanoparticles mainly gold and silver with an overview of their potential applications.

Synthesis and LCST Behavior of Thermosensitive Poly (N-isopropylacrylamide)-Clay Nanocomposites

Sur, Gilsoo,Lyu, Sung-Gyu,Chang, Jin-Hae 한국공업화학회 2003 Journal of Industrial and Engineering Chemistry Vol.9 No.1

Thermosensitive polymer-clay nanocomposites were prepared via organically modified clay-poly(N-isopropylacrylamide) (PNIPAM) nanocomposites. Nanocomposites containing a 5 wt% montmorillonite exhibited a lower critical solution temperature (LCST) similar to the unmodifed PNIPAM hydrogel, and similar phenomena with a large thermal volumetric change and transition kinetics compared to conventional PNIPAM gels. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) suggested that the clay minerals in the nanocomposite were partially exfoliated in a dried state and mostly exfoliated in a swollen state.

Automatic Acquisition of Class-based Rules for Word Alignment

( Sur Jin Ker ),( Jason J. S. Chang ) 한국언어정보학회 1995 국제 워크샵 Vol.1995 No.-

In this paper, we describe an algorithm for aligning words with their translation in a bilingual corpus. Existing algorithms require enormous bilingual data to train statistical word-to-word translation models. Using word-based approach, frequent words with consistent translation can be aligned at a high precision rate. However, less frequent words or words with diverse translations usually do not have statistically significant evidence for confident alignment. Incomplete or incorrect alignments consequently result. Our algorithm attempts to handle the problem using a hierarchical class-based approximation of translation probabilities. The translation probabilities are estimated using class-based models on 3 levels of specificity. We found that the algorithm can provide translation probability for more word pairs at the cost of slightly lower degree of precision, even when a small corpus was used in training. We have achieved an application rate of 81.8% and precision rate of93.3%. The algOrithm also offer the advantage of producing word-sense disambiguation information.

서석훈,홍경민,신용섭,김성보,서길수,신부영 한국공업화학회 2002 응용화학 Vol.6 No.2

Mechanical properties and gas permeability of biodegradable Pectin/Starchmontmorillonite clay (filler) have been studied. Tensile strength and modulus was increased as the increasing content of montmorillonite. X-ray diffraction was used to assess the periodic distance of the clay layers and transmission electron microscopy was used to to observe the composite morphology. The periodic distance of the stacks was 21.76∼26.12 Å for the processed composites. Thus suggests that the layers of the clay particles have been intercalated. Oxygen permeability of pectin/starch-clay composites was generally lower than that of plastic films.
