The nucleation and growth of crystalline cobalt nanoparticles (Co NPs) under solvothermal conditions can be separated into distinct stages by using (i) polynuclear clusters with multivalent capping ligands to initiate nucleation, and (ii) thermolabile organometallic complexes with low autonucleation potential to promo…
THz and DC losses in crystalline states of GeSbTe and AgInSbTe phase-change material systems are re-examined and discussed. Although a simple free carrier transport has been assumed so far in the GeSbTe (GST) system, it is shown through recent experimental results that a series sequence of intragrain and intergrain (t…
Patchy colloids are promising candidates for building blocks in directed self-assembly, but large scale synthesis of colloids with controlled surface patterns remains challenging. One potential fabrication method is to self-assemble the surface patterns themselves, allowing complex morphologies to organize spontaneous…
Water-soluble fluorescent carbon dots (CDs) have been synthesized in one step by hydrothermal treatment of potato. Effects of the hydrothermal treatment time, temperature, potato additive amount and pH on the light emissions of the CDs were also studied. HRTEM images of the CDs showed spherical particles with fairly u…
Herein, we report the synthesis of 2nd generation PPDs functionalized with free thiol moieties within the scaffold, which were used as anchor points for the covalent attachment of guest species (p-nitrophenol derivatives) through the oxidative formation of disulfide linkages. The disulfide bonds were then cleaved unde…
Real part of complex relative dielectric value is relatively decreased as large as ∼5 % from 50 K to 200 K in CaCu3Ti4O12, by applying a 6-T static magnetic field. CaCu3Ti4O12 is thus implied primarily by the negative magnetodielectric effect, as a unified dielectric system in which 1-D finite dipole chains of B-site…
Sr 2 FeMoO 6 ceramics with different Fe / Mo antisite defect ( ASD ) concentrations and grain‐boundary ( GB ) properties were prepared. The competitive and combining effects of GB and Fe / Mo ASD on the transport and magnetoresistance were discussed. The GB properties, that is, intergrain coupling strength, positively…
The assembly of high molecular weight polypeptides into complex architectures exhibiting structural complexity ranging from the nano- to the mesoscale is of fundamental importance for various protein-related diseases but also hold great promise for various nano- and biotechnological applications. Here, the aggregation…
Ti–6Al–4V is widely used to prepare biomedical implant for orthopaedic and dental applications, but it is an expensive choice relative to other implant materials such as stainless steels and Co–Cr alloys, in large part due to the high manufacturing cost. Adding boron to refine the as cast microstructure of Ti–6Al–4V c…
Direct observation of corrosion phenomena under special environments is still a challenge. Here, we reported on an in situ method for CO2 corrosion imaging under high pressure. The simultaneously recording of the surface morphology changes and Fe ions release can clearly reveal the detailed process of CO2 corrosion fr…
Chalcogenide alloys can exist in both crystalline and amorphous phases, with light-induced changes between the two states. While it is generally believed that in the amorphization process light predominantly serves to melt the material that is subsequently quenched into the amorphous phase, there has been accumulating…
The effect of friction stir processing followed by an aging heat treatment on an extruded α/β dual-phase Mg–8.5Li–2.8Al–1.1Zn (LAZ931) alloy is investigated. The aim of present study is to explore its microstructural characteristic and tensile mechanical properties. The friction stir process reduces the extruded textu…
Pressure-induced stacking sequence variations of gold are predicted from first-principles calculations. At the static condition, the ABC stacking in the face-centered-cubic (fcc) phase changes into ABCACB above at least 200 GPa, and then into ABAC corresponding to the double hexagonal-close-packed structure. By furthe…
Methylated nitrogen-substituted microporous and mesoporous silica exhibited almost the same catalytic performance as that of a conventional homogeneous base catalyst. They also demonstrated unexpectedly high product selectivity for the Morita-Baylis-Hillman reaction of formaldehyde with methyl acrylate at high tempera…
Oat spelt arabinoxylan (OsAX) and spruce galactoglucomannan (GGM) are hemicelluloses that can be extracted in large quantities from sidestreams of the agriculture and forest industries. They both form selfstanding films, making them potential future packaging materials. This systematic study focuses on the effect of l…
A new methodology to calculate efficiently the absorption spectrum of a single molecule when subjected to mechanical stress is presented. As example, the developed methodology was applied to cis- and trans-azobenzene, commonly used as photoswitch in a wide variety of applications. The results show that both (1)(n,π*)…
This article reports on the thermal instability of functionally graded (FG) annular microplates with different boundary conditions. The modified strain gradient elasticity theory is employed to capture size effects. The non-linear governing equations and boundary conditions are derived based on the first-order shear d…
Performance prediction of thermoelectric generators (TEG) is an important work in thermoelectrics and a physical model is quite necessary. Now basic thermoelectric phenomena have been expounded explicitly, modeling a TEG is an accessible work. However, the Thomson heat (which is a second-order effect) is usually negle…
The correlation between calcination temperature and properties (physical and electrochemical) of composite cathodes comprising lanthanum strontium cobaltite ferrite (LSCF) with samarium-doped ceria carbonate (SDCC) has been investigated. LSCF-SDC carbonate (LSCF-SDCC) composite cathode powders prepared via ball-millin…
The effect of eco-degradant PD 04 as additive on the thermal properties of recycled polyethylene (RPE)/chitosan biopolymer was investigated. The different scanning calorimetric (DSC) was used to investigate the thermal properties of composites at various 0, 20 and 40 php. The DSC result shows the presence of eco-degra…
