The n‐type semiconducting spinel zinc ferrite (ZnFe2O4) is used as a photoabsorber material for light‐driven water‐splitting. It is prepared for the first time by atomic layer deposition. Using the resulting well‐defined thin films as a model system, the performance of ZnFe2O4 in photoelectrochemical water oxidation i…
Electrochemical carbon dioxide (CO 2 ) reduction is an emerging technology for efficiently recycling CO 2 into fuel, and many studies of this reaction are focused on developing advanced catalysts with high activity, selectivity, and durability. Of these catalysts, oxide-derived metal nanoparticles, which are prepared…
Atherosclerosis is the key pathogenesis of cardiovascular disease, which is a silent killer and a leading cause of death in the United States. Atherosclerosis starts with the adhesion of inflammatory monocytes on the activated endothelial cells in response to inflammatory stimuli. These monocytes can further migrate i…
Cation‐disordered lithium‐excess metal oxides have recently emerged as a promising new class of high‐energy‐density cathode materials for Li‐ion batteries, but the exploration of disordered materials has been hampered by their vast and unexplored composition space. This study proposes a practical methodology for the i…
The performance of a photovoltaic device is strongly dependent on the light harvesting properties of the absorber layer as well as the charge separation at the donor/acceptor interfaces. Atomically thin two-dimensional transition metal dichalcogenides (2-D TMDCs) exhibit strong light-matter interaction, large optical…
By incorporating novel subwavelength structures into macroscopic materials, acousticians can create devices with exotic sound-altering properties.
Abstract Purpose: The blood–brain barrier (BBB) is modified to a blood–tumor barrier (BTB) as a brain metastasis develops from breast or other cancers. We (i) quantified the permeability of experimental brain metastases, (ii) determined the composition of the BTB, and (iii) identified which elements of the BTB disting…
Recent rapid growth of the world's population has increased food demands. This phenomenon poses a great challenge for food manufacturers in maximizing the existing food or plant resources. Nowadays, the recovery of health benefit bioactive compounds from fruit wastes is a research trend not only to help minimize the w…
In broad terms, hydrothermal synthesis is a technology for crystallising materials (chemical compounds) directly from aqueous solution by adept control of thermodynamic variables (temperature, pressure and composition). The objective of this review is to introduce the field of hydrothermal materials synthesis and show…
Abstract Visible light communication (VLC) is an emerging technology that uses light-emitting diodes (LEDs) or laser diodes for simultaneous illumination and data communication. This technology is envisioned to be a major part of the solution to the current bottlenecks in data and wireless communication. However, the…
Trap distribution of the low-density polyethylene(LDPE) modified by anhydride grafting agent was studied and the effect of grafting agent on the trap levels was analyzed by the method of Photo-stimulated Discharge in this paper. Different concentrations and types of same concentration of LDPE modified by anhydride gra…
Cr2AlC powders using Cr/Al/C and Cr/Al/Cr3C2 systems as raw materials were successfully synthesised by a microwave hybrid heating method for the first time. The mixtures of Cr, Al and graphite or Cr3C2 with different molar ratios were used to investigate the formation of Cr2AlC phase. For Cr/Al/C with the molar ratios…
Quenched random fields (RFs) are well-known to be a basic driving force of the peculiar behavior of relaxor ferroelectrics such as PbMg1/3Nb2/3O3 (PMN), SrxBa1-xNb2O6 (SBN), and BaTi1-xZrxO3 (BTZ), hence, giving rise to strong frequency dispersion of the dielectric response, an apparent lack of macroscopic symmetry br…
Single-phase, near-stoichiometric zinc stannate (Zn 2 SnO 4 ) nanowires were synthesized by a direct vapor transport process on c -Al 2 O 3 substrates under optimized growth conditions. The optimal growth temperature for Zn 2 SnO 4 nanowires is above 700 °C. Structural characterization indicates that the nanowires had…
Nematic liquid crystals (NLCs) form helical macroscopic structures through chiral induction when doped with chiral species. We describe a very simple, though highly sensitive method for determination of handedness and pitch of the induced twist in the case of very weak twisting powers of such chiral dopants. A tiny dr…
본 연구에서는 poly(lactic acid)(PLA), poly(butylene adipate-co-terephthalate)(PBAT), ethanolamine(MEA) 블렌드를 제작하였다. MEA는 PLA/PBAT의 에스터 치환반응을 가능하게 하였고, 커플링반응의 촉매로써 작용하였으며, PLA와 PBAT간의 상용성을 증진하게 하였다. PLA/PBAT/MEA 블렌드의 구조 및 열적 특성을 관찰하였고, PLA/PBAT/MEA 블렌드를 PLA/PBAT 블렌드의 커플링제로 사용하였다. 결론적으로 PLA/PBAT/MEA 블렌드는 화학적 결합으로 인하여 상용성을 향상하였…
A series of 4,4ʹ-dialkoxy-3,3ʹ-diaminobiphenyl compounds were synthesised by three-step procedure that involves alkylation, nitration and reduction reactions. Their chemical structures were characterised by FTIR, 1H and 13C spectroscopy and elemental analysis. Their thermotropic liquid–crystalline (LC) properties were…
The aim of this article is to develop a robust macroscopic bi-axial model to capture self-accommodation, martensitic transformation/orientation/reorientation, normal–shear deformation coupling and asymmetric/anisotropic strain generation in polycrystalline shape memory alloys. By considering the volume fraction of mar…
Epitaxial films are a useful tool to study the interplay between the microstructure and the electrocaloric properties in order to optimize the performance of these materials. Therefore, epitaxial 0.9Pb(Mg1/3Nb2/3)O3-0.1PbTiO3 (PMN-PT) films were grown by pulsed laser deposition on (001)-oriented single crystalline SrT…
