, UZM-22 and ECR-40-type FOMS), which has never been recognized or addressed before. The overall characterization results of this work demonstrate that the proportion of the zeolite domain in such solid-solutions varies significantly with the number of OH groups in OSDAs.
Four raw deposits clayey materials in Burkina Faso have been characterized using X-ray diffraction, infrared spectroscopy and ICP-AES to evaluate their suitability to be used as pozzolan in cement. The samples have been activated by thermal treatment at 730°C during 5 hours. The obtained metakaolin was investigated by…
Increasing importance is being placed on the role of drug solubilisation in the drug development pipeline. In order for drugs to successfully pass through the pre-clinical studies required before clinical trials they often require addition of excipients or solubility modifying agents. This study highlights the use of…
A new class of hollow microporous carbon nanospheres with good electrochemical performances was fabricated through a facile hypercrosslinking strategy.
Agents that are capable of killing pathogenic microorganisms are known as Antimicrobial Substances. These are of low molecular weight and used for the sterilization of water, as antimicrobial drugs, as food preservatives, and for soil sterilization. Due to their potential to provide quality and safety benefits to many…
Optimization of atom transfer radical polyadditions using commercially available catalytic systems allowed obtaining control over the polyester architecture and functionality and functional linear polyesters with high molecular weight ( M w = 16 200).
A novel bowl-like carbon backbone supported CoFe 2 O 4 nanoparticles composite was facilely synthesized to favour enhancing of reversible lithium storage.
In situ build root-like glass fiber (GF) via molecular self-assemble in polypropylene melts.
Synchrotron X-ray diffraction (XRD) was used to measure the unit-cell parameters of synthetic pyrope (Mg 3 Al 2 Si 3 O 12 ), grossular (Ca 3 Al 2 Si 3 O 12 ), and four intermediate garnet solid solutions. Garnets synthesized dry in multi-anvil (MA) apparatus at 6 GPa show irregular asymmetric positive quench- able exc…
For application to exploration under the surface of icy objects in the solar system, the penetration of an impact probe into an icy target was experimentally simulated by using the ballistic range. Slender projectiles with a cylindrical body and various nose shapes were tested at the impact velocity 130 - 420 m/s. The…
l -Amino acid deaminases (LAADs; EC 1.4.3.2) belong to a family of amino acid dehydrogenases that catalyze the formation of α-keto acids from l -amino acids.
The optimization of dual dielectric layers by incorporating poly(vinyl alcohol) (PVA), poly(methyl methacrylate) (PMMA), polystyrene (PS) or poly(4-vinylphenol) (PVP) in combination with Al2O3 resulted in immensely improved OFET characteristics with N,N'-bis(cyclohexyl)naphthalene diimide (NDI-CY2) as the active mater…
In this paper, phenoxazinium was used as a fluorophore for the design of pH probes by the photoinduced electron transfer (PET) mechanism. Phenoxazinium with an aliphatic morpholinyl group (probe ) gave increased emission at 665 nm with pH ranging from 7.4 to 4.4; meanwhile, the other one with an aromatic diethylaminop…
An integrated computational approach, based on molecular dynamics and density functional theory, reveals an interplay between morphology, processing and charge transport properties in layered aggregates of PTCDI-C13.
Bamboo-like vertically standing LFP nanotube bundles enable a better accessibility for Li-ion movement along 1D-channels in b -axis of olivine structure.
The highly polymorphic compound ROY, notorious for the colour of its crystals, was the subject of an optimised high-throughput ultrasound-based co-crystal screen. This screen involved a computational pre-screen which highlighted an interaction between ROY and the potential co-former pyrogallol. We have shown that the…
An effective strategy involving the corrosion of partial-surface-passivated Cu nanoparticles is proposed for synthesizing transition-metal-based Cu-Au alloy nanocages. Time-dependent X-ray absorption spectroscopy demonstrates that the hollow-cage Cu-Au alloy nanostructure is formed by sequential erosion of the partial…
The aprotic Na–O 2 battery has attracted significant interest over the past few years because of its high theoretical specific energy and uncompromised round-trip efficiency. So far, most of the Na–O 2 studies, using a cell configuration of Na metal anode, aprotic Na + electrolyte and porous O 2 cathode, focus on the…
In the first part of the work, we described our concept of shock wave processes, which is based on nonlocal nonequilibrium transport theory, and an associated mathematical elastoplastic wave model that allows for inertial properties, structural changes, and variation in mechanical properties of solid-state materials u…
The present paper reports the design, development and evaluation of methyl methacrylate (MMA) and acrylonitrile (AN) copolymers to improve viscoelastic and surface properties critical to scratch resistance.
