A multimodal optical/paramagnetic nanoprobe, Den-Angio, was developed and demonstrated a capability to circumvent the blood brain barrier (BBB) and visualize brain tumors with high sensitivity in vivo. Den-Angio holds promise to pre-operatively localize brain tumors and make image-guided tumor resection possible durin…
Polypropylene composites of snail shell powder were prepared at filler contents, 0 to 40 wt%. The particle sizes of the snail shell powder investigated were 0.150, 0.30, and 0.42 µm. Talc, of particle size, 0.150 µm was used as the reference filler. The polypropylene composites were prepared in an injection moulding m…
We present a facile synthesis of manganese oxide (MnO(2)) nanocomposite with ultraviolet (UV) photosensitive characteristic by a solid-state reaction based on the reduction of potassium permanganate (KMnO(4)) by aniline, which provides a new family and more selectivity for UV photosensitive nanomaterials in the future.
We describe the preparation and properties of supramolecular hydrogels produced by spontaneous self-association of disodium guanosine 5′-monophosphate (Na25′GMP) in the presence of Ag+ ions. Hydrogels with increasing viscosity are prepared by increasing the GMP:Ag stoichiometry from a molar ratio of 1 : 1 to 1 : 2. In…
The prospect of rendering objects invisible has intrigued researchers for centuries. Transformation optics based invisibility cloak design is now bringing this goal from science fictions to reality and has already been demonstrated experimentally in microwave and optical frequencies. However, the majority of the invis…
Polymer-based composite materials are ideal for applications where high stiffness-to-weight and strength-to-weight ratios are required. From aerospace and aeronautical field to biomedical applications, fiber-reinforced polymers have replaced metals, thus emerging as an interesting alternative. As widely reported, the…
Surface integrity of machined products has a critical impact on their functional performance. Magnesium alloys are lightweight materials for transportation industry and are also emerging as a potential material for temporary biomedical implants. However, their unsatisfactory corrosion resistance limits their applicati…
Recent advances in the fast-growing area of block-like structures based on electroactive oligomers, with a particular focus on tetra(aniline)-based structures, are discussed in this review. We provide an overview of recent literature covering aspects of design of novel molecular architectures, synthetic strategies and…
The reaction of N,N'-dibenzyl-2-amino-4-imino-pent-2-ene, nacnac(Bn)H, with 1 or 2 equiv. of MgnBu₂ afforded the homoleptic complex nacnac(Bn)₂Mg. The reaction of nacnac(Bn)H with Mg(N(SiMe₃)₂)₂ yielded nacnac(Bn)MgN(SiMe₃)₂, which reacted with tert-butanol to form nacnac(Bn)MgOtBu. The latter complex crystallizes as…
In the present work, fabrics of intentionally changed structure were measured in the range of their basic structural parameters and thermal insulation properties. Cotton woven fabrics of different weaves, linear densities of the weft and different weft densities were the objects of the investigation. The thermal insul…
The Bi(2)S(3) nanomaterials with various morphologies such as nanorods, nanowires, nanowire bundles, urchin-like microspheres and urchin-like microspheres with cavities have been successfully synthesized through a simple hydrothermal method. Experimental results indicate that sulfur sources play crucial roles in deter…
This mini-review highlights some of the recent progress of using cryostructuration for the production of porous materials.
A facile approach to synthesize Zn(x)Cu(y)InS(1.5+x+0.5y) nanocrystal emitters was presented. The compositions of these nanocrystals were precisely controlled, and the relative PL quantum yields were up to 40%, with tunable emissions in 450-640 nm.
Crystal-liquid interfaces in nickel are investigated by molecular-dynamics computer simulations. Inhomogeneous systems of size L x × L y × L z with L z =5 L y are prepared where the crystal fcc phase at different orientations coexists with the liquid phase, separated by planar interfaces in the xy -plane. The lateral…
We report temperature dependent measurements of birefringence (Δn), splay (K11), bend (K33) elastic constants and rotational viscosity (γ1) of mixtures of rod-like and bent-core molecules. K11 and Δn remain almost constant for all the mixtures whereas K33 is always lower than K11 and further decreases with increasing…
Development of reliable and eco-friendly processes for synthesis of metallic nanoparticles is an important step in the field of application of nanotechnology. In this study, we report the synthesis of silver nanoparticles using the leaf extracts of Euphorbia hirta and Nerium indicum. Synthesized particles are characte…
Theranostic applications require coupling of diagnosis and therapy, a high degree of specificity and adaptability to delivery methods compatible with clinical practice. The tunable physical and biological effects of selective targeting and activation of plasmonic nanobubbles (PNB) were studied in a heterogeneous biolo…
An amorphous blue phase III with low and wide thermal range (∼20 °C) including room temperature is induced by doping a bent-core nematic with a strong chiral material. We confirm that the electrooptical response is due to the Kerr effect, with the Kerr constant being up to two orders of magnitude larger than conventio…
We describe the successful synthesis of the first mixed-cation (pseudoternary) amidoborane, Na[Li(NH(2)BH(3))(2)], with theoretical hydrogen capacity of 11.1 wt%. Na[Li(NH(2)BH(3))(2)] crystallizes triclinic (P1) with a = 5.0197(4) Å, b = 7.1203(7) Å, c = 8.9198(9) Å, α = 103.003(6)°, β = 102.200(5)°, γ = 103.575(5)°,…
Among the porphyrin molecules with different metal insertion sites and functional ligands, Zn-porphyrin most efficiently regenerates NADH through photo-induced electron transfer in the presence of [Cp*Rh(bpy)H(2)O](2+), a rhodium-based electron mediator. Photochemical regeneration of NADH by Zn-porphyrin is successful…
