1Mechanical properties and flame retardancy of surface modified magnesium oxysulfate(5Mg(OH)_(2)·MgSO_(4)·3H_(2)O)whisker for polypropylene composites显示文摘Magnesium oxysulfate(MOS)whisker is considered as a promising inorganic material recently attracting a great attention for being used as a reinforcing filler for polymer composites due to high aspect ratio and extremely-low bulk density.In this study,the MOS was treated with 3-methacryloyloxypropyl-trimethoxy silane(MPS)via sol-gel condensation reactions,which successfully allowed melt mixing with polypropylene(PP)up to 30 wt%of MOS.The tensile strength at yield and modulus of the MOS/PP composites were substantially increased by 50.8%and 362%,respectively,when compared with the pristine PP.As a novel finding,the flame retardancy of MOS was proved by identifying water evolution at elevated temperatures giving out 9 wt%of water in 250-320℃and 14 wt%in 350-420℃in two steps.This work demonstrated that the MOS could be an excellent filler for PP not only increasing the mechanical properties in a great extent but also imposing flame retarding capability.Eui-Su Kim Ye Chan Kim Jungwoo Park Youngjun Kim Sung-Hoon Kim Kwang Jin Kim Jonghwan Suhr Youngkwan Lee Seong Hoon Lee Dae-Sik Kim Soo-Hyun Kim Ju-Ho Yun In-Kyung Park Jae-Do Nam 2018Journal of Materiomics2018,4,2:9

5An overview of two dimensional materials显示文摘Research on two dimensional(2D)materials,one of the most extensively studied classes of materials,has grown rapidly over the past several years and attracted great attention of thousands of scientists from across materials science,physics,chemistry,engineering,medicine and industry.This research activity has triggered the emergence of a new generation of atomically thin metals,semimetals,semiconductors,nitrides,oxides/hydroxides,transition metal dichalcogenides(TMDs),topological insulators and even polymers,demonstrating the potential for novel properties and technological innovations.The topics of the special issue include TMDs and transition metal oxides(TMOs),graphene and graphene-derived materials,black phosphorus(BP),2D metals,and related heterostructures/hybrids/composites and their potential applications in energy,environment,electronics,and biology fields.Hongwei Zhu Jonghwan Suhr Renzhi Ma 2018Journal of Materiomics2018,4,2:1

7Mechanical properties of nanocomposites reinforced by carbon nanotube sponges显示文摘Carbon nanotube(CNT)sponge exhibits unique porous and hierarchical structure that are beneficial to the design of ultralight and tough composites.In this study,CNT sponges(undoped and boron doped)reinforced polydimethylsiloxane(PDMS)composites were fabricated.Mechanical properties of the composite,including compressive modulus,rate-dependent modulus,stress relaxation behaviors,dynamic viscoelastic properties,and their dependency on temperature,were systematically investigated.A micromechanical model,Mori-Tanaka model,was validated to describe the mechanical behaviors of CNT sponge reinforced composites.By coupling with boron-doped CNT sponge,PDMS composites showed remarkable improvement of mechanical properties,including compressive modulus(70%),viscous modulus(243%)and damping capacity(50%).Such reinforcement effects can be controlled by the morphology of CNT sponges,as the boron-doped and undoped nanocomposites showed distinct viscoelastic behaviors.The results proved that CNT sponge reinforcement is a promising strategy to develop engineering composites with both outstanding mechanical stiffness and controllable viscoelastic performances.Wenjie Zhao Tong Li Yupeng Li Daniel J.O'Brien Mauricio Terrones Bingqing Wei Jonghwan Suhr X.Lucas Lu 2018Journal of Materiomics2018,4,2:1

15High-damping and conducting epoxy nanocomposite using both zinc oxide particles and carbon nanofibers显示文摘In this study,high-damping and conducting epoxy nanocomposites were developed with carbon nanofibers as conducting materials,and zinc oxide particles as piezoelectric materials.The mechanical and electrical properties,electrical impedance,and loss factors were investigated by uniaxial tensile tests,voltage measurement,impedance measurement,and 3-point bending tests.Two percolation thresholds were found:the percolation threshold of resistivity due to the carbon nanofibers forming conductive networks in the matrix;and the impedance threshold due to the zinc oxide particles acting like electric barriers.A poling treatment of the high-damping and conducting epoxy nanocomposite was considered,and we found that poling treatment helped to make the networks more conductive and to generate voltage from ZnO particles.A high-damping and conducting epoxy nanocomposite with 3 wt%CNF and 10 wt%ZnO exhibited higher loss factor than those of others tested.Jae-Soon Jang Gyo Woo Lee Hyung-ick Kim Sung Yong Hong Lijie Ci Jae-Do Nam Jonghwan Suhr 2018Journal of Materiomics2018,4,3:0
16An HI intensity mapping survey with a Phased Array Feed显示文摘We report results from a neutral hydrogen(H I)intensity mapping survey conducted with a Phased Array Feed(PAF)on the Parkes telescope.The survey was designed to cover 380 deg^(2)over the redshift range 0.3=1.32±0.42 m K(statistical errors only).A future Parkes cryogenic PAF is expected to detect the cross-correlation signal with higher accuracy than previously possible and allow measurement of the cosmic H I density at redshifts up to unity.Lin-Cheng Li Lister Staveley-Smith Jonghwan Rhee 2021Research in Astronomy and Astrophysics2021,21,2:0
17手机购物APP设计认知研究——以中国用户体验为例显示文摘手机购物APP的便利性与即时互动性,使得手机购物APP成为移动手机网民生活中不可或缺的一部分。但普通用户对产品的使用问题并不能给予准确地反馈,这会造成用户与产品之间产生无形的阻碍。因此了解用户对手机购物APP的使用认知体验,对研究改善手机购物APP设计有着重要的意义。本论文以问卷调查的形式通过使用Q-方法论对不同年龄和职位的33名用户进行33个Q样本调查分类,同时,主成分分析由QUANL PC程序执行。通过调查得出用户对购物APP设计的认知体验评价显示出四种不同的认知因子,总结如下:'简洁设计型认知'、'加强监督型认知'、'用户自主型认知'和'定位准确型认知'。冯佳囡 Jonghwan Seo 2021中国包装2021,41,2:0

19Super-elastic and mechanically durable MXene-based nanocomposite aerogels enabled by interfacial engineering with dual crosslinking strategy显示文摘Recently,MXenes have attracted considerable attention owing to their unique physical and chemical properties.Construction of MXenes to three-dimensional(3D)porous aerogel structures can play a critical role in realizing the profound implications of MXenes,especially for environmental remediation.Nevertheless,developing mechanically robust MXene-based aerogels with reversible compressibility under harsh conditions,such as liquid environments,remains challenging due to the insufficient interfacial strength between MXene nanosheets.Herein,3D porous MXene-based nanocomposite aerogels are developed by dual physical and chemical crosslinking strategy with poly(vinyl alcohol)and formaldehyde in this study.The developed MXenebased nanocomposite aerogels with designed interfacial engineering exhibit outstanding structural stability and extremely high reversible compressibility up to 98%strain as well as unprecedented mechanical durability(2000 cycles at 50%strain)in water environment.Moreover,the aerogels show adaptable compressibility when exposed to different solvents,which is explained with the Hansen solubility parameter.Thanks to their high compressibility in water,the robust MXene-based aerogels exhibit excellent methylene blue adsorption performance(adsorption capacity of 117.87 mg·g^(−1))and superior recycling efficiency(89.48%at the 3rd cycle).The porous MXene-based nanocomposite aerogels are also demonstrated with outstanding thermal insulation capability.Therefore,by synergistically taking their porous structure and super elasticity in liquid environment,the MXene-based aerogels show great promise in diverse applications including adsorption and separation,wastewater purification desalination,and thermal management.Yan Sun Xin Yang Ruonan Ding Sung Yong Hong Jinwoo Lee Zongfu An Mei Wang Yifei Ma Jae-Do Nam Jonghwan Suhr 2023Nano Research2023,16,5:0
