This review provides a comprehensive overview of the progress in light-material interactions(LMIs), focusing on lasers and flash lights for energy conversion and storage applications. We discuss intricate LMI parameters such as light sources, interaction time, and fluence to elucidate their importance in material processing. In addition, this study covers various light-induced photothermal and photochemical processes ranging from melting, crystallization, and ablation to doping and synthesis, which are essential for developing energy materials and devices. Finally, we present extensive energy conversion and storage applications demonstrated by LMI technologies, including energy harvesters, sensors, capacitors, and batteries. Despite the several challenges associated with LMIs, such as complex mechanisms, and high-degrees of freedom, we believe that substantial contributions and potential for the commercialization of future energy systems can be achieved by advancing optical technologies through comprehensive academic research and multidisciplinary collaborations.

Changes in microorganisms and metabolites during long-term fermentation of commercially manufactured anchovy sauce

Food Science and Human Wellness 2024年

This study was performed to investigate the changes in microbial communities and metabolites during the long-term fermentation of commercially manufactured anchovy sauce. Samples of commercial anchovy sauce were collected from large-scale fermentation tanks with fermentation periods of up to 7.87 years. The complex bacterial community was simplified to two genera， Tetragenococcus and Halanaerobium， after approximately 0.55 years of fermentation. Although genera， such as Saccharomyces， Cladosporium， Candida， and Aspergillus， were relatively dominant， no clear pattern was identified in fungal community analysis. The longitudinal metabolite profile demonstrated that approximately half (55.8%) of the metabolites present in anchovy sauce were produced within a year of fermentation due to rapid fermentation. Despite the static microbial community， the contents of several metabolites including amino acids and biogenic amines changed continuously during the long-term fermentation of anchovy sauce. This study provides novel insights into the changes in microbiota and metabolites in fish sauce produced without any starter inoculation.

Random pinhole attenuator for high-power laser beams

引用

High Power Laser Science and Engineering 2024年第3期 121-126页

作者： Seong Cheol park Hyeok Yun Jin Woo Yoon Seong Ku Lee jae Hee Sung Il Woo Choi Chang Hee Nam Kyung Taec Kim Department of Physics and Photon Science Gwangju Institute of Science and Technology Center for Relativistic Laser Science Institute for Basic Science Advanced Photonics Research Institute Gwangju Institute of Science and Technology

The intensity attenuation of a high-power laser is a frequent task in the measurements of optical science. Laser intensity can be attenuated by inserting an optical element, such as a partial reflector, polarizer or absorption filter. These devices are, however, not always easily applicable, especially in the case of ultra-high-power lasers, because they can alter the characteristics of a laser beam or become easily damaged. In this study, we demonstrated that the intensity of a laser beam could be effectively attenuated using a random pinhole attenuator(RPA), a device with randomly distributed pinholes, without changing the beam properties. With this device, a multi-PW laser beam was successfully attenuated and the focused beam profile was measured without any alterations of its characteristics. In addition, it was confirmed that the temporal profile of a laser pulse, including the spectral phase, was preserved. Consequently, the RPA possesses significant potential for a wide range of applications.

AIM:To ascertain whether the Prague circumferential(C) length and maximal(M) length criteria for grading the extent of Barrett's esophagus can be applied prior to its widespread application in South ***:Two hundred and thirteen consecutive cases with endoscopic columnar-lined esophagus(CLE) were included and classified according to the Prague C and M ***:Of 213 cases with CLE, the distribution of maximum CLE lengths was: 0.5-0.9 cm in 99 cases(46.5%); 1.0-1.4 cm in 63 cases(29.6%); 1.5-1.9 cm in 15 cases(7.0%); 2.0-2.4 cm in 14 cases(6.6%); 2.5-2.9 cm in 1 case(0.5%); and 7.0 cm in 1 case(0.5%). Twenty cases(9.4%) had columnar islands alone. Two hundred and eight cases(97.7%) lacked the circumferential CLE component(C0Mx). Columnar islands were found in 70 cases(32.9%), of which 20 cases(9.4%) had columnar islands ***:In regions where most CLE patients display short or ultrashort tongue-like appearance, more detailed descriptions of CLE's in < 1.0 cm lengths and columnar islands, as well as avoidance of repeating the prefix "C0" need to be considered in parallel with the widespread application of the Prague system in South Korea.

Variability of the Dokdo Abyssal Current observed in the Ulleung Interplain Gap of the East/Japan Sea

引用

Acta Oceanologica Sinica 2013年第1期32卷 12-23页

作者： KIM Yun-Bae CHANG Kyung-Il park jae-Hun park jong Jin East Sea Research Institute Korea Institute of Ocean Science and Technology Research Institute of Oceanography School of Earth and Environmental Sciences Seoul National University Ocean Science Research Department Korea Institute of Ocean Science and Technology Department of Oceanography Kyungpook National University

Subinertial fluctuation of a strong northward deep current, which is referred to the Dokdo Abyssal Current （DAC） by Chang et al. （2009）, is investigated from current records for about 16.5 and 8.0 months in the Ulle- ung Interplain Gap of the East/lapan Sea. The current below 300 m is bottom-intensified and has nearly depth-independent flow. Near bottom, the spectral peaks of the current were found near 10, 20, and 60 d. The DAC variability near 10 d and 20 d is reasonably consistent with the linear theory of topographic Rossby waves （TRWs） in the following aspects：（1） The motion is columnar and bottom-intensified; （2） the theo- retical cutoff frequency is similar to the observation; （3） The observation-based angles of the wavenumber vector are in good agreement with the theoretical ones. The wavelengths of the TRWs with periods of near 10 d and 20 d near Dokdo are significantly shorter than those with similar timescales in the open oceans （100-250 km）. It is primarily due to the weak stratification below 300 m in the East Sea. The deep cur- rent fluctuations with periods of near 10 d and 20 d were accompanied by warm events in the upper layer resulting from eddying processes and/or meandering of the Tsushima Warm Current.

Application of signal processing techniques to the detection of tip vortex cavitation noise in marine propeller

引用

Journal of Hydrodynamics 2013年第3期25卷 440-449页

作者： LEE Jeung-Hoon HAN jae-Moon park Hyung-Gil SEO jong-Soo Samsung Ship Model Basin (SSMB) Marine Research Institute Samsung Heavy Industries Science TownDaejeon 305-380 Korea

The tip vortex cavitation and its relevant noise has been the subject of extensive researches up to now. In most cases of experimental approaches, the accurate and objective decision of cavitation inception is primary, which is the main topic of this paper. Although the conventional power spectrum is normally adopted as a signal processing tool for the analysis of cavitation noise, a faithful exploration cannot be made especially for the cavitation inception. Alternatively, the periodic occurrence of bursting noise induced from tip vortex cavitation gives a diagnostic proof that the repeating frequency of the bursting contents can be exploited as an indication of the inception. This study, hence, employed the Short-Time Fourier Transform （STFT） analysis and the Detection of Envelope Modulation On Noise （DEMON） specmma analysis, both which are appropriate for finding such a repeating frequency. Through the acoustical measurement in a water tunnel, the two signal processing techniques show a satisfactory result in detecting the inception of tip vortex cavitation.
