1Rumen methanogens and mitigation of methane emission by anti-methanogenic compounds and substances显示文摘Methanogenic archaea reside primarily in the rumen and the lower segments of the intestines of ruminants, where they utilize the reducing equivalents derived from rumen fermentation to reduce carbon dioxide, formic acid, or methylamines to methane(CH_4). Research on methanogens in the rumen has attracted great interest in the last decade because CH_4 emission from ruminants contributes to global greenhouse gas emission and represents a loss of feed energy. Some DNA-based phylogenetic studies have depicted a diverse and dynamic community of methanogens in the rumen. In the past decade, researchers have focused on elucidating the underpinning that determines and affects the diversity, composition, structure, and dynamics of methanogen community of the rumen. Concurrently, many researchers have attempted to develop and evaluate interventions to mitigate enteric CH_4 emission. Although much work has been done using plant secondary metabolites, other approaches such as using nitrate and 3-nitrooxy propanol have also yielded promising results. Most of these antimethanogenic compounds or substances often show inconsistent results among studies and also lead to adverse effects on feed intake and digestion and other aspects of rumen fermentation when fed at doses high enough to achieve effective mitigation. This review provides a brief overview of the rumen methanogens and then an appraisal of most of the antimethanogenic compounds and substances that have been evaluated both in vitro and in vivo. Knowledge gaps and future research needs are also discussed with a focus on methanogens and methane mitigation.Amlan Patra Tansol Park Minseok Kim Zhongtang Yu 2017Journal of Animal Science and Biotechnology2017,8,2:21
2Quantitative comparisons of select cultured and uncultured microbial populations in the rumen of cattle fed different diets显示文摘Background: The number and diversity of uncultured ruminal bacterial and archaeal species revealed by 16S rRNA gene (rrs) sequences greatly exceeds that of cultured bacteria and archaea. However, the significance of uncultured microbes remains undetermined. The objective of this study was to assess the numeric importance of select uncultured bacteria and cultured bacteria and the impact of diets and microenvironments within cow rumen in a comparative manner. Results: Liquid and adherent fractions were obtained from the rumen of Jersey cattle fed hay alone and Holstein cattle fed hay plus grain. The populations of cultured and uncultured bacteria present in each fraction were quantified using specific real-time PCR assays. The population of total bacteria was similar between fractions or diets, while total archaea was numerically higher in the hay-fed Jersey cattle than in the hay-grain-fed Holstein cattle. The population of the genus Prevotella was about one log smaller than that of total bacteria. The populations of Fibrobacter succinogenes, Ruminococcus flavefaciens, the genus Butyrivibrio, and R. albus was at least one log smaller than that of genus Prevotella. Four of the six uncultured bacteria quantified were as abundant as F. succinogenes, R. flavefaciens and the genus Butyrivibrio. In addition, the populations of several uncultured bacteria were significantly higher in the adherent fractions than in the liquid fractions. These uncultured bacteria may be associated with fiber degradation. Conclusions: Some uncultured bacteria are as abundant as those of major cultured bacteria in the rumen. Uncultured bacteria may have important contribution to ruminal fermentation. Population dynamic studies of uncultured bacteria in a comparative manner can help reveal their ecological features and importance to rumen functions.Minseok Kim Zhongtang Yu 2012Journal of Animal Science and Biotechnology2012,3,4:7
3Field-effect transistor with a chemically synthesized MoS2 sensing channel for label-free and highly sensitive electrical detection of DNA hybridization显示文摘A field-effect transistor (FET) with two-dimensional (2D) few-layer MoS2 as a sensing-channel material was investigated for label-free electrical detection of the hybridization of deoxyribonucleic acid (DNA) molecules. The high-quality MoS2-channel pattern was selectively formedthrough the chemical reaction of the Mo layer with H2S gas. The MoS2 FET was very stable in an electrolyte and inert to pH changes due to the lack of oxygen-containing functionalities on the MoS2 surface. Hybridization of single-stranded target DNA molecules with single-stranded probe DNA molecules physically adsorbed on the MoS2 channel resulted in a shift of the threshold voltage (Vt,) in the negative direction and an increase in the drain current. The negative shift in Vth is attributed to electrostatic gating effects induced by the detachment of negatively charged probe DNA molecules from the channel surface after hybridization. A detection limit of 10 fM, high sensitivity of 17 mWdec, and high dynamic range of 106 were achieved. The results showed that a bio-FET with an ultrathin 2D MoS2 channel can be used to detect very small concentrations of target DNA molecules specifically hybridized with the probe DNA molecules.Doo-Won Lee Jinhwan Lee II Yung Sohn Bo-Yeong Kim Young Min Son Hunyoung Bark JaehyuckJung Minseok Choi Tae Hyeong Kim Changgu Lee Nae-Eung Lee 2015Nano Research2015,8,7:3

11Integrated metasurfaces for re-envisioning a near-future disruptive optical platform显示文摘Metasurfaces have been continuously garnering attention in both scientific and industrial fields,owing to their unprecedented wavefront manipulation capabilities using arranged subwavelength artificial structures.To date,research has mainly focused on the full control of electromagnetic characteristics,including polarization,phase,amplitude,and even frequencies.Consequently,versatile possibilities of electromagnetic wave control have been achieved,yielding practical optical components such as metalenses,beam-steerers,metaholograms,and sensors.Current research is now focused on integrating the aforementioned metasurfaces with other standard optical components(e.g.,light-emitting diodes,charged-coupled devices,micro-electro-mechanical systems,liquid crystals,heaters,refractive optical elements,planar waveguides,optical fibers,etc.)for commercialization with miniaturization trends of optical devices.Herein,this review describes and classifies metasurface-integrated optical components,and subsequently discusses their promising applications with metasurface-integrated optical platforms including those of augmented/virtual reality,light detection and ranging,and sensors.In conclusion,this review presents several challenges and prospects that are prevalent in the field in order to accelerate the commercialization of metasurfaces-integrated optical platforms.Younghwan Yang Junhwa Seong Minseok Choi Junkyeong Park Gyeongtae Kim Hongyoon Kim Junhyeon Jeong Chunghwan Jung Joohoon Kim Gyoseon Jeon Kyung-il Lee Dong Hyun Yoon Junsuk Rho 2023Light(Science & Applications)2023,12,8:1

19Prospects of Huygens’ Metasurfaces for Antenna Applications显示文摘1.Introduction In recent years,there has been an intense research effort by the international community in the field of“artificial”electromagnetic materials,or“metamaterials.”Metamaterials are engineered structures that induce a tailored arrangement of magnetic and electric dipole moments when excited by an incident electromagnetic field.Under certain conditions,such as when the comprising unit cells are sub-wavelength,metamaterials can be homogenized and described in terms of macroscopic constitutive parameters such as permeability,permittivity,and refractive index.A summary of the early work on“artificial dielectrics”can be found in Ref.[1].In the over 20-year-old field of metamaterials,the desired macroscopic parameters correspond to extreme properties such as negative permittivity,negative permeability,and a negative refractive index.Perhaps the most recognized metamaterial is that which realizes a negative refractive index,originally demonstrated at microwaves and based on a unit cellmade out of a split-ring resonator and a wire[2].In the engineering community,a transmission-line approach was developed for implementing metamaterials with significant advantages,such as reduced transmission losses and wider operating bandwidths[3,4].George V.Eleftheriades Minseok Kim Vasileios G.Ataloglou Ayman H.Dorrah 2022Engineering2022,8,4:0
