Over the past several years, a new surge of interest in paper electronics has arisen due to the numerous merits of simple micro/nanostructured substrates. Herein, the latest advances and principal issues in the design and fabrication of paper-based flexible electronics are highlighted. Following an introduction of the…
Abstract Recently, the pursuit of high photoluminescence quantum yields (PLQYs) for blue emission in perovskite nanocrystals (NCs) has attracted increased attention because the QY of blue NCs lags behind those of green and red ones severely, which is fatal for three-primary-color displays. Here, we propose an in situ…
Photodynamic therapy is arising as a noninvasive treatment modality for cancer and other diseases. One of the key factors to determine the therapeutic function is the efficiency of photosensitizers (PSs). Opposed to traditional PSs, which show quenched fluorescence and reduced singlet oxygen production in the aggregat…
Surface metal adsorption on 2D structures is demonstrated to be an effective tool for improving hydrogen storage capacity. In the current work, the behavior of Ca atom adsorption on monolayer MoS2 is studied and subsequently its hydrogen storage capacity is investigated computationally using van der Waals (vdW) revise…

In the present study, effect of CNT on optical and thermal properties of mixed thermotropic liquid crystal mixture was studied by various techniques to understand their physical behavior. Some new mesophases have investigated by optical methods viz. Polarizing Optical Microscopy (POM) and Fabry–Perot Scattering Studie…
Toward enhancement of intercolumnar electronic communications in thermotropic columnar liquid-crystalline (LC) materials, we report LC crown ether-decorated phthalocyanine with the shortest intercolumnar distance among LC phthalocyanines. Moreover, the liquid crystallinity was variable by the introduction of square-pl…
To develop high performance and low cost microfluidic devices, heterogeneous bonding with cyclo-olefin polymer (COP) and glass substrate was investigated by low pressure plasma using water vapor. COP and glass-like substrate were bonded at room temperature under its own weight, and the bonding strength reached the bre…
An amino acid ionic liquid tetramethylammonium glycinate ([N 1111 ][Gly]) and an organic supramolecular gelator N -lauroyl- l -glutamic acid di- n -butylamide (GP-1) were used as structure-directing agents for the fabrication of mesoporous alumina with diverse morphologies via a solvothermal synthetic method. The irre…
Abstract Ab initio molecular dynamics simulations are performed to investigate the atomic structures and dynamics of Ni 64 Zr 36 and Ni 65 Hf 35 metallic liquids in a temperature range of 1400–2500 K. Calculated results are in good agreement with recently reported high temperature experimental data. Local atomic struc…
Ultrathin crystalline CeO 2 (111) films were grown on Ru(0001) in order to study the interaction of HCl with this surface as a first step of the Deacon reaction with experimental techniques, including low energy electron diffraction (LEED), scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), a…
Background: Reactive oxygen species are formed through the electron transfer reactions in the mitochondria and chloroplasts and rapidly converted to H2O2.Therefore, H2O2 as a more stable ROS can be considered as an indicator of cellular stress and it can be used in a steady state to monitor intracellular stress level.…
PLA는 친환경 생분해성 플라스틱으로 식품용 포장재 및 3D 프린트용 필라멘트로 주로 사용되고 있다. 본 연구에서는 친환경 천연 충전재인 셀룰로오스 나노크리스탈(CNC)을 PLA에 충전한 복합재의 물성을 조사하였다. PLA/CNC 나노복합재는 용융혼합 및 압축성형에 의해 제조하였다. CNC의 함량에 따른 PLA/CNC 나노복합재들의 인장특성, 충격강도 및 열적 특성을 각각 측정하였다. CNC의 함량이 늘어날수록 나노복합재의 결정화도, 인장 강도 및 인장 탄성률은 증가하였지만 유리전이온도, 냉각결정화 시작 온도 및 파단 신율은 감소하였다. 충격강도는 CNC 1 phr…
