A new type of photothermally responsive nanoprobe based on Edman degradation has been synthesized and characterized. Under irradiation by an 808 nm laser, the heat generated by the gold nanorod core breaks the thiocarbamide structure and releases the fluorescent dye Cy5.5 with increased near-infrared (NIR) fluorescenc…
1-Octanethiol-coated Cu nanoparticles were mixed with reduced graphene oxide (rGO) to fabricate Cu nanoinks with enhanced oxidation prevention. Graphene oxide (GO) was synthesized using modified Hummer’s method and rGO was reduced from GO using hydrazine hydrate. Copper nanoinks were fabricated with varying concentrat…
The Dipole Quadrupole theory of Surface Enhanced Hyper Raman Scattering (SEHRS), created by the authors is expounded in detail. Peculiarities of behavior of electromagnetic field on rough metal surfaces are considered. It is demonstrated that there is an enhancement of the dipole and quadrupole light-molecule interact…
Hydrogen-induced cold cracking of welds needs to be solved to promote the application of high-strength steel. Cold cracking has been investigated through slit-type weld cracking tests. These tests afford appropriate conditions to avoid cold cracking in terms of factors such as chemical composition, hydrogen concentrat…
Magnesium hydroxide [Mg(OH)2] nanoparticles were prepared using a novel impinging stream-rotating packed bed reactor (IS-RPB). Magnesium chloride and sodium hydroxide were used as the reactants. The effects of several synthesis parameters, such as the initial concentration of Mg2+, rotation speed, liquid flow rate, re…
The synthesis, crystal structure and physical properties of new disodium trans-diaquabis(oxalato)cobaltate(ii)hexahydrate {Na2[Co(C2O4)2(H2O)2]·6H2O} crystals have been investigated. Single crystal X-ray analysis reveals that this compound crystallizes in the triclinic system with the space group P1[combining macron].…
A theoretical-guided design concept aiming to achieve highly efficient unidirectional charge transfer and multi-charge separation upon successive photoexcitation for light-harvesting dyes in the scope of supramolecular photocatalysts is presented. Four 4H-imidazole-ruthenium(ii) complexes incorporating a biimidazole-b…
This paper presents 2D generalized plain strain simulations of the thermo-mechanical response of a pellet fragment and overlying cladding during a RIA transient. A fictitious hydride blister of increasing depth (25 to 90% of the clad thickness) is introduced at the beginning of the calculation. When a pre-determined h…
This study discusses the substituent effect on molecular conformation and packing, exploring the driving force for different molecular aggregations.
The environmental concern has been raised due to the abundance of waste from synthetic materials which cannot be biodegraded after their life-time. It provides opportunity to exploit natural resources which are neglected. For example, midrib wastes from zalacca plants after cutting are able to utilize as composite rei…
The interaction of DNA and the large planar structures of graphene quantum dots is investigated by absorption spectroscopy, gel electrophoresis, circular dichroism, and melting temperature.
The notch-bend strength (σb,max) was investigated for High Si Solid Solution Strengthened Ferritic Ductile Cast Iron (EN-GJS-500-14) with varying the strain rate at room temperature. The notch-bend strength was also compared with the conventional ferrite-pearlite type ductile cast iron JIS-FCD500 and JIS-FCD700. Then,…
We report the self-assembly behaviour of five water soluble arylene diimides based on benzene, naphthalene and perylene moieties, by utilizing the essentiality of two major reversible supramolecular interactions, π-stacking and hydrogen bonding.
Supramolecular nanocarriers transport complementary reactants inside living cells in consecutive internalization steps to allow their reaction exclusively in the intracellular space with the formation of a fluorescent product.
As there has been an increasing trend in using nonwovensnatural fiber in composites, there is a need to find good micromechanical models to represent their behavior. In this study,randomly oriented nonwoven kenaf/epoxy composites at various fiber loading has been fabricated by using resin transfer moulding (RTM) metho…
The salt of neodymium has been widely used in industrial polymerization of 1,3-butadiene. We used the ternary catalytic system neodymium versatate/diethylaluminum chloride/triisobutylaluminum (NdV 3 /DEAC/TIBA) with 0.5 mM NdV 3 /100 g Bd, NdV 3 : DEAC = 1 : 9 mol : mol, and TIBA = 25, 50, 100, and 200 mM. The number-…
In this attempt, silver nanoparticles were prepared and surface-modified with polythiophene. Nano-sized polythiophene nanoparticles were synthesized using H2O2 and CuSO4·5H2O, whereas silver nanoparticles were prepared using sol-gel route. Later composite nanoparticles of PTh and Ag (PThNP/s-AgNP) were prepared and lo…
The morphologies and surface structures of particles with different compositions are vital for determining their properties and applications. But the morphological and structural changes associated with the composition changes of MgO precursors and the physicochemical properties of the obtained MgO are barely studied.…
This manuscript investigates the creep performance of β-iPP with different crystalline morphologies.
As the simplest two-dimensional (2D) polymer, graphene has immensely high intrinsic strength and elastic stiffness but has limited toughness due to brittle fracture. We use atomistic simulations to explore a new class of graphene/polyethylene hybrid 2D polymer, "graphylene", that exhibits ductile fracture mechanisms a…
