The Ni–P incorporated citric acid (CA) catalysts with different CA/Ni molar ratios ( x ) were successfully prepared. The introduction of CA can change the structure of the catalyst precursor by complexing, and therefore affect the catalyst pore structures. The incorporation of CA into bulk Ni–P catalyst leads to a dra…
The exploitation of by-products from chemical processes shows high potential for the development of new synthesis routes for valuable chemicals.Glycerol, provided as a by-product from the biodiesel manufacturing process, is a potential feedstock chemical.From dihydroxyacetone, a primary oxidation product of glycerol,…
The synthesis of methyl acetate via esterification of acetic acid with methanol is a prominent example of equilibrium-limited esterification reactions with low reaction rates in the absence of catalysts. The acidic ion-exchange resin Amberlyst 15 is a potential heterogeneous catalyst. The aim of this study was to inve…
A series of naphthalene diimide‐based conjugated polymers are prepared with various molar percentage of low molecular weight polystyrene (PS) oligomer of narrow polydispersity as the side chain. The PS side chains are incorporated through preparation of a macromonomer by chain termination of living anionic polymerizat…
Sub-1 nm, extremely long nickel molybdate nanowires are synthesized based on a good/poor solvent system. The ultrathin nanowires can be hierarchically assembled into flexible, free-standing films with good mechanical properties. Compared with the large-size counterpart, nickel molybdate ultrathin nanowires display pro…
Abstract The field of nanobiocatalysis has experienced a rapid growth due to recent advances in nanotechnology. However, biocatalytic processes are often limited by the lack of stability of the enzymes and their short lifetime. Therefore, immobilization is key to the successful implementation of industrial processes b…
Catalyst-containing nanoreactors have attracted considerable attention for specific applications. Here, we initially report preparation of PtNi@SiO2 hollow microspheres based on confined catalysis. The previous encapsulation of dispersed Pt nanoparticles (NPs) in hollow silica microspheres ensures the formation of Pt@…
Flexible free-standing carbonized cellulose-based hybrid film is integrately designed and served both as paper anode and as lightweight current collector for lithium-ion batteries. The well-supported heterogeneous nanoarchitecture is constructed from Li4Ti5O12 (LTO), carbonized cellulose nanofiber (C-CNF) and carbon n…
Perovskite‐based solar cells are generally assembled as planar structures comprising a flat organoammonium metal halide perovskite layer, or mesoscopic structures employing a mesoporous metal‐oxide scaffold into which the perovskite material is infiltrated. To present, little attention has been directed toward the tex…
Magnetic metal-organic framework (MOF) composites show highly efficient CO2 desorption capacities upon their exposure to an alternating magnetic field, demonstrating a magnetic induction swing strategy for potentially low-energy regeneration of MOF adsorbents.
A series of metal phosphides (MoP, WP, Co 2 P, Fe 2 P and Ni 2 P) were synthesized by H 2 -temperature-programmed reduction method. Amongst these phosphides, Fe 2 P was found to show a considerably higher activity for NO dissociation than other phosphides. Herein, it was firstly used as a catalyst for NO reduction wit…
Solvent properties of aqueous media (dipolarity/polarizability, hydrogen bond donor acidity, and hydrogen bond acceptor basicity) were measured in the coexisting phases of Dextran-PEG aqueous two-phase systems (ATPSs) containing .5 and 2.0 M urea. The differences between the electrostatic and hydrophobic properties of…
Montmorillonite (MMT) clay has properties that would find applications in biotechnological and biomedical fields. In this study, naturally occurring MMT clay was purified using sedimentation and centrifugation techniques. Characterization of the prepared materials was done using X-ray Florescence (XRF), Fourier Transf…
The mineralogical and chemical characteristics, based on X-ray diffraction (XRD) and scanning electron microscopy, of a kaolin known as DD3, from eastern Algeria were examined in the present study. The results showed that kaolin DD3 has an alumina content of 39%. The SiO2/Al2O3 molar ratio of 2.14 is close to that of…
New magnetic surfactants, (cationic hexadecyltrimethlyammonium bromotrichlorogadolinate (CTAG), decyltrimethylammonium bromotrichlorogadolinate (DTAG), and a magnetic polymer (poly(3-acrylamidopropyl)trimethylammonium tetrachlorogadolinate (APTAG)) have been synthesized by the simple mixing of the corresponding surfac…
Texture evolution is studied by EBSD in Mg–9Gd–4Y–0.4Zr (GW94), Mg–5Gd–4Y–0.4Zr (GW54), and Mg–5Gd–0.4Zr (GW50) alloys after processing with two extrusion‐ratios of 19:1 and 8:1. While the alloys show common extrusion textures at the low extrusion‐ratio of 8:1, an unusual extrusion texture is observed in the GW94 allo…
Wire-shaped flexible supercapacitors (SCs) have aroused much attention due to their small size, light weight, high flexibility, and deformability. However, the previously reported wire-shaped SCs usually involve complex assembly processes, encounter potential structural instabilities, and the influence of dynamic bend…
Layer-by-layer (LbL) self-assembly is a versatile technique from which multicomponent and stimuli-responsive nanoscale drug carriers can be constructed. Despite the benefits of LbL assembly, the conventional synthetic approach for fabricating LbL nanoparticles requires numerous purification steps that limit scale, yie…
In this work we investigated thin films of the ferrimagnetic insulators YIG and NFO capped with thin Pt layers in terms of the longitudinal spin Seebeck effect (LSSE). The electric response detected in the Pt layer under an out-of-plane temperature gradient can be interpreted as a pure spin current converted into a ch…
Well-defined graphene quantum dots (GQDs) are crucial for their biological applications and the construction of nanoscaled optoelectronic and electronic devices. However, as-synthesized GQDs reported in many works assume a very wide lateral size distribution; thus, their apparent properties cannot truthfully reflect i…
