Abstract The application of living microbial cells as molecular engines for a variety of biotechnological applications including cell‐based biosensing is an ongoing research effort. However, there are significant difficulties to overcome such as the fragile structures of microbial cells and the weak efficiency of deve…
We perform numerical simulations of non-Brownian suspensions in the laminar flow regime to study the scaling behavior of particle clusters and collisions under shear. As the particle fraction approaches the maximum packing fraction, large transient clusters appear in the system. We use methods from percolation theory…
Successful biological development via spatial and temporal regulations of cell differentiation relies on the action of multiple signaling molecules that are known as morphogens. It is now well established that biological signaling molecules create nonuniform concentration profiles, called morphogen gradients, that act…
A hierarchical porous carbon fiber with high nitrogen doping was fabricated for high-performance supercapacitor. For the purpose of high nitrogen retention, the porous polyacrylonitrile fiber was treated by hydrazine hydrate, and then underwent pre-oxidation, carbonization, and activation in sequence. The resulted mat…
This review deals with one of the surface modification techniques, chemical conversion coating and particularly cerium-based conversion coatings (CeCC) as a promising substitute for chromium and phosphate conversion coating on magnesium and its alloys. The CeCCs are commonly considered environmentally friendly. The ef…
Aluminum is a common metal that is used extensively in daily life. However, over-exposure to aluminum may result in nervous system-related diseases. Thus, it is important to develop a rapid sensing method that can be used to screen samples. In this study, glutathione-capped gold nanoclusters with bright photoluminesce…
We report the high-resolution electron Compton profiles of graphite along three main crystallographic directions of [101¯0], [112¯0], and [0001] by recording electron energy-loss spectra at a large momentum transfer using a transmission electron microscope. A significant anisotropy is observed. The experimental result…
Some pyridopyrimidine derivatives with high biological activity have been investigated as photostabilizers for rigid Poly(vinyl chloride) (PVC). Their stabilizing efficiencies were evaluated by determining the percentage of weight loss, the amount of formed gel, as well as the intrinsic viscosities, of the photodegrad…
This work focused on two difficulties associated with preparation of polypropylene/wood flour (PP/WF) composites, viz. the compatibility of PP with WF and processing of the composites with high melt viscosity. Maleic anhydride‐grafted polypropylene (MAPP) was used in the preparation of PP composites to provide the com…
The magnetic and structural properties of island-structured LTP MnBi fabricated onto MgO single crystal substrates are discussed. The size and height of the “Volmer-Weber” type islands vary from place to place but are averagely a few microns and sub-microns, respectively. From the wetting angle (40 ∼ 60°) of those isl…
In this study, poly(amide‐imide)s are synthesized for electronic materials by adding amide groups into polyimide. As it is expected, poly(amide‐imide) shows an amorphous structure with a lower glass transition temperature and residual stress than the neat polyimide due to the high steric hindrance of the amide group.…
In this work, we fabricated multi-layer WSe2 rectifying diodes using graphene oxide (GO) as p-doping material on one side of the contacting electrodes. This GO layer can reduce the contact resistance by forming a tunneling barrier for efficient hole injection, while it increases the contact resistance for the injectio…
본 연구는 돈피 젤라틴 첨가에 따른 유화형 소시지의 이화학적 특성을 조사하였다. 처리구별로 유화형 소시지 제조 시 젤라틴 함량을 0%, 1%, 3%, 5%를 첨가하여 제조하였다. 일반성분 측정 결과 수분 함량은 대조구에 비해 젤라틴 3%와 5% 첨가구가 유의적으로 높았으며(P0.05), 단백질 함량은 젤라틴 5% 첨가구가 대조구와 젤라틴 1% 첨가구보다 유의적으로 높은 결과를 나타내었다(P0.05). 또한 지방은 감소하는 경향을 보였으나 유의적인 차이는 없었다. pH는 가열 전후 모두 젤라틴 첨가 함량이 증가할수록 유의적으로 증가하였다(P0.05). 색도 측정 결과…
In this study, sisal fiber–cement composites reinforced with 4% and 6% of short fibers were developed, and their physical-mechanical behavior was characterized. To ensure the sustainability and durability of the composites, the ordinary Portland cement matrix was modified by adding fly ash and metakaolin, and the natu…
In this work we have observed a remarkable improvement in the thermoelectric (TE) performance of In 6– x Sn x Se 7 ( ZT = ∼0.28 at x = 0.1, 833 K) compared to that of pristine In 6 Se 7 ( ZT = 0.015 at 640 K). This improvement is mainly attributed to the creation of active donor defects Sn In 3+ as Sn(4+) is energetic…
Physisorbed water originating from exposure to the ambient can have a strong impact on the structure and chemistry of oxide nanomaterials. The effect can be particularly pronounced when these oxides are in physical contact with a solid substrate such as the ones used for immobilization to perform electron or ion micro…
Friction tests using ZrO 2 (Y-PSZ: yttria partially stabilized zirconia) pin slid against polymer-like carbon film of bilayer and multilayer structures under H 2 gas environment are conducted. It will be shown that friction coefficients of the level of 0.0001 (friction fade-out) is stably realized by adding alcohol va…
The optical response of graphene-MoS2 heterojunctions is investigated. Spatial resolution photoresponse maps obtained using multiple bias conditions are measured and analyzed by exciting the graphene-MoS2 heterojunction area, MoS2, and Ti-MoS2 junction on the same device with an 800 nm wavelength Ti-Sapphire raster sc…
Abstract Exciton–phonon coupling and nonradiative relaxation processes have been investigated in near-infrared (NIR) emitting ternary alloyed mercury cadmium telluride (CdHgTe) quantum dots. Organically capped CdHgTe nanocrystals of sizes varying from 2.5–4.2 nm have been synthesized where emission is in the NIR regio…
The two dimensional nature of graphene, with charge carriers confined within one atomic layer thickness, causes its electrical, optical, and sensing properties to be strongly influenced by the surrounding media and functionalization layers. In this study, the effect of catalytically active Pd nanoparticle (NP) functio…
