A series of Pd-, Ce-, Co-, and Ti- doped OMS-2 catalysts were prepared by a one-step hydrothermal method. The removal of o -xylene by a combination of metal-doped OMS-2/γ-Al 2 O 3 catalysts and nonthermal plasma was systematically investigated. Catalysts were characterized by inductively coupled plasma optical emissio…
Nanomechanical properties of morphotropic BiFeO3 thin films are characterized at the nanoscale, using a combination of scanning probe microscopy techniques. Several key insights into the structural, mechanical, and electrical property correlations are presented. Besides, an approach employing nanomechanical force has…
Graphene placed on hexagonal boron nitride (h-BN) has received a wide range of interest due to the improved electrical performance and rich physics from the interface, especially the emergence of superlattice Dirac points as well as Hofstadter butterfly in high magnetic field. Instead of transferring graphene onto h-B…
Nano-twinned structures are mechanically stronger, ductile and stable than its non-twinned form. We have investigated the effect of varying twin spacing and twin boundary width (TBW) on the yield strength of the nano-twinned copper in a probabilistic framework. An efficient surrogate modelling approach based on polyno…
We have performed the first-principles calculations on the structural, electronic, and magnetic properties of 3d transition-metal™ (Cr, Mn, Fe, Co, and Ni) atoms doped 2D GaN nanosheet. The results show that 3d TM atom substituting one Ga leads to a structural reconstruction around the 3d TM impurity compared to the p…
Graphene oxide/polyimide (GO/PI) composites with different loadings of GO were prepared by in situ polymerization and solution blending method. By adding GO, the mechanical, electrical, and thermal properties of composites could be improved. The tensile strength of GO/PI composite with 3.0 wt% GO loading was up to 137…
The prevention of refractory organic pollution caused by conventional dyeing and the development of new fabrics with various functions are two issues to be solved urgently in the field of textile fabrication. Here, we report a new environmentally friendly route for the simultaneous coloration and functionalization of…
In order to optimize materials for phase change random access memories (PCRAM), the effect of Ge doping on Ga-Sb alloy crystallization was studied using combined in situ synchrotron x-ray techniques, electrical measurements, and static laser testing. The present data emphasize that the crystallization temperature can…
The development of highly sensitive and selective methods for the detection of lead ion (Pb(2+)) is of great scientific importance. In this work, we develop a new surface-enhanced Raman scattering (SERS)-based sensor for the selective trace measurement of Pb(2+). The SERS-based sensor is assembled from gold nanopartic…
Three alkali swelling methods were used to treat two kinds of kraft pulp fibers. The morphological and chemical properties of the treated fibers were elucidated in terms of alkali concentration, with the aim of developing bulky paper and conserving wood resources. The effects of beating before and after alkali swellin…
Abstract Glycerol is a byproduct of the biodiesel industry. The target of the following work was to produce a biopolyester based on glycerol, and to blend it with poly(lactic acid) (PLA) to increase its ductility. Microwave synthesis was used to conduct the reactions of glycerol with a diacid (sebacic acid) and a mono…
The combination of CdSe semiconductor nanocrystals with 9-anthracene carboxylic acid ligands can sensitize triplet–triplet annihilation on the emitter molecule diphenylanthracene. This hybrid system has recently been shown to upconvert visible light (532 nm) to ultraviolet light (420 nm) (Huang, Z., et al. Nano Lett .…
A synthetic approach for the preparation and linkage of functionalized plasticizer molecules to PVC is described. The synthesis of this four-step procedure is economically and ecologically viable because it is based on trichlorotriazine as inexpensive starting material; the reactions can be carried out one-pot with qu…
The inclusion complexes formed by chalcone and 2',4'-dihydroxychalcone with β-cyclodextrin have been studied combining experimental (phase solubility diagrams, Fourier transform infrared spectroscopy) and molecular modeling (molecular dynamics, quantum mechanics/molecular mechanics calculations) techniques. The format…
The ability to control interparticle forces not only improves the existing nanoparticle (NP) functionalities but paves the way for newer properties as well. A proof of concept in this direction is presented here, wherein the regulation of interparticle forces—revealing controlled aggregation—has been successfully tran…
Listeria monocytogenes is a serious foodborne pathogen that can contaminate food during processing and can grow during food shelf-life. New types of safe and effective food contact materials embedding antimicrobial agents, like silver, can play an important role in the food industry. The present work aimed at evaluati…
By means of periodic density functional calculations, we have studied the effect of dual doping on the stability and electronic structure of graphene. To this end, we substituted two carbon atoms with one 2p element (B, N, or O) and one 3p element (Al, Si, P or S). We determined that, in all cases, dual doping is much…
ABSTRACT The optimization of the processing conditions in the production of soy protein bioplastics by injection molding has been essential in order to develop materials with a great capacity to absorb water while displaying good mechanical properties. Using a 50/50 (wt/wt) soy protein/glycerol mixture, and 40 °C, 500…
Here, we describe a general bioluminescence resonance energy transfer (BRET) homogeneous immunoassay based on quantum dots (QDs) as the acceptor and Renilla luciferase (Rluc) as the donor (QD-BRET) for the determination of small molecules. The ratio of the donor-acceptor that could produce energy transfer varied in th…
We propose theoretically that the reactivity of O 2 -bound Cu-ZSM-5 toward methane is enhanced by the presence of one water molecule near a dinuclear copper site inside a 10-membered ring of the zeolite cavity. The current study employed density functional theory (DFT) calculations with the B3LYP functional to elucida…
