Metalloproteins and metalloenzymes play important roles in biological systems by using the limited metal ions, complexes, and clusters that are associated with the protein matrix. The design of artificial metalloproteins and metalloenzymes not only reveals the structure and function relationship of natural proteins, b…
The “fast selective catalytic reduction (SCR)” process, with its superior efficiency, is promising for removing NO x from flue gas with low temperature and high gas velocity. Chemisorption of NO 2 is a crucial step in this heterogeneous catalysis process. In this study, density functional theory calculations and exper…
Hybrid interfaces between living cells and nano/microstructured scaffolds have huge application potential in biotechnology, spanning from regenerative medicine and stem cell therapies to localized drug delivery and from biosensing and tissue engineering to neural computing. However, 3D architectures based on semicondu…
Transition metals, such as Fe, are commonly used in either layers or substrates to serve as deep intentional acceptors to realize semi-insulating substrates, regrowth interfaces, or buffer layers. The unintentional incorporation of the compensating acceptor in subsequent layers is a major concern in epitaxial growth.…
The morphology controlled synthesis of porous vaterite microparticles from amorphous calcium carbonate (ACC) nanoparticles via mesoscale transformation and self-assembly is presented. The morphology of vaterite microparticles ranging from ellipsoidal to spherical can be controlled by adjusting the amount of adipic aci…
A semilocal exchange-correlation functional is proposed with the efficient prediction of the solid-state band gap. The underlying construction of the exchange functional is based on the modeling of the exchange hole and constructing the exchange energy functional. Being a meta-generalized gradient approximation (meta-…
Dairy manufacturing sector generates large quantity of nutrient-rich wastewater which requires treatment before it can be released into the environment. This study aimed to use a low-cost food grade sodium lignosulphonate (Na-lignosulphonate) to recover proteins and lipids from dairy wastewater and reduce the BOD. The…
Unlike catalytic reactions thermally driven by metal nanoparticles, reaction rates in photocatalysis do not scale with either the density of nanoparticles or their size. Because of the complexity of multicomponent photocatalysts in powder form, this lack of correlation, routinely observed for decades, is still not und…
This work deals with the size-dependent buckling response of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) (FG-CNTRC) curved beams based on a higher-order shear deformation beam theory in conjunction with the Eringen Nonlocal Differential Model (ENDM). The material properties were estimated using…
Abstract Nowadays, the increasing demands from consumer challenges the traditional leather products. Traditional polymer leather finishes gradually lose their dominant position in the market. To address this issue, recent research effort has been devoted to developing polymer-based organic-inorganic nanocomposite leat…
Catalytic conversion of methane to value-added chemicals is a promising application for gas versatility. In this work, we have investigated the methane oxidation over oxygen-rich IrO 2 (110) surface by DFT calculations, as IrO 2 is reported to be an effective catalyst for activating the C–H bond of methane. Compared t…
In this study, the structural behavior of small-scale wood beams externally strengthened with various fiber strengthened polymer (FRP) composites (i.e., flax FRP (FFRP), basalt FRP (BFRP), E-glass FRP ("E" stands for electrical resistance, GFRP) and their hybrid FRP composites (HFRP) with different fiber configuration…
Laser-induced photochemical reduction of aqueous [AuCl 4 ] − is a green synthesis approach requiring no chemical reducing agents or stabilizers; but size control over the resulting gold nanoparticles remains a challenge. Under optical breakdown conditions producing hydrated electrons (e aq – ) and hydroxyl radicals (O…
Nanocomposite tectons (NCTs) are a recently developed building block for polymer-nanoparticle composite synthesis, consisting of nanoparticle cores functionalized with dense monolayers of polymer chains that terminate in supramolecular recognition groups capable of linking NCTs into hierarchical structures. In princip…
Abstract BACKGROUND Considering the large amounts of by‐products derived from orange processing, which are generally discarded, the present study aimed to explore the feasibility of using orange peel for lactic acid production in solid state fermentation. RESULTS Different species of lactic acid bacteria were employed…
In recent years, the development and wide application of micro-electronic technology brings forward high demands for active thermal management systems. However, such systems are not only costly, but also usually tethered, and need constant power to operate. To avoid such a limitation, smart thermal management systems…
Micro-scale mechanical characterization of materials is a useful technique for understanding local material behavior, particularly where inhomogeneous materials or microstructures are present. In this work, a custom microsample testing system that utilizes digital image correlation (DIC) is used to measure the respons…
A series of Rh-based intermetallic compounds supported on silica was prepared and tested in alkene hydrogenation at room temperature. H2 and D2 were used as the hydrogen sources and the kinetic isotope effect (KIE) in hydrogenation was studied. In styrene hydrogenation, the KIE values differed strongly depending on th…
Porous activated carbon (AC) is prepared by the steam activation of biochar prepared from pyrolyzed pine nut shell as a precursor. The effects of various activation temperatures, activation times and steam flow rates on the structure and properties of the obtained ACs are compared and analyzed. The cyclic voltammetry,…
Au/ZnO prepared by coprecipitation exhibited extremely high catalytic activity for low-temperature CO oxidation below room temperature. The catalytic activity was influenced by the reduction atmosphere in the preparation and the heat treatment in air before the reaction. Reduction of Au III by H 2 not only gave smalle…
