Solid lipid nanoparticles (SLN) stabilized by nonionic polysorbate or block copolymer surfactants were used for the preparation of hierarchical meso–macroporous silica through a co-templated approach combining a cooperative templating mechanism (CTM) with micelles and spherical soft matter particles imprinting. Depend…
One-pot salt metathesis reaction of anhydrous LnCl3 with one equivalent of guanidinate lithium [(SiMe3)2NC(NCy)2]Li (Cy = cyclohexyl), following the introduction of two equivalents of NaN(SiMe3)2 or LiN(SiHMe2)2 in THF at room temperature, afforded a family of mono(guanidinate) rare earth metal bis(amide) complexes [(…
Highly ordered semiconducting metal oxide nanorod arrays on transparent and flexible substrates are promising materials for modern optoelectronic and electronic devices, such as touch screens, flexible displays, and printable electronics components. Herein, a modified nanocrystal-seed-directed-hydrothermal route has b…
Regenerable hydrogen storage of lithium amidoborane is firstly achieved through the routes of direct thermal dehydrogenation and subsequent chemical hydrogenation of its dehydrogenated products by treatment with hydrazine in liquid ammonia.
Fine-tuning the design of polymer-doxorubicin conjugates permits optimization of an efficient nanocarrier to greatly increase intracellular uptake and cytotoxicity. Here, we report synthesis of a family of self-assembled polymer-doxorubicin nanoparticles and an evaluation of the effects of various types of side-chains…
Efficient delivery of anti-cancer drugs into tumor cells for enhancing the intracellular drug concentration is a major challenge for cancer therapy due to the instability of drug-loading vehicle. In this report, we developed a simple method to stabilize the nanostructure of micelles only by bubbling air to crosslink t…
Mesoporous nanoparticles functionalized with amino groups on the pore surface and quaternary ammonium groups on the particle surface with particle sizes of 500–800 nm in length and 300–500 nm in diameter and a pore size of 7.2–7.4 nm, have been obtained through a post-synthesis and co-condensation method. Bleomycin (B…
We newly synthesized various sized gold nanoparticles covered with photochromic polymers consisting of diarylethenes with various structures to investigate an effect of the gold nanoparticles on the photocycloreversion reaction of the diarylethene chromophores upon irradiation with visible light. The gold nanoparticle…
Ternary intermetallic compounds, Mg2−xPrxNi4 (0.6 ≤ x ≤ 1.4) were synthesized by induction melting and investigated with respect to hydrogenation properties and structural changes. These compounds have a cubic C15b-type Laves structure (space group F-43m), where Mg and Pr have an ordered arrangement. The lattice param…
Two series of phenylbenzylether and benzanilide based rod-like imidazolium bromides and their nonionic precursors, the 1-phenyl-1H-imidazoles have been synthesized and the influence of the number and length of the alkyl chain(s) and the structure of the linking group in the aromatic core (–CH2O–, –COO–, –CONH–) on the…
We describe the elaboration of nanostructured transparent conducting indium tin oxide (ITO) materials that is based on controlled self-assembly of ultra-small indium tin hydroxide nanoparticles. We developed a strategy for preparing nanosized, nearly spherical and highly dispersible nanoparticles of indium tin hydroxi…
The influence of high temperature synthesis of MCM-41 on structural ordering, textural properties and stability has been investigated. Increasing the crystallization temperature resulted in the enlargement of pore size and some reduction of long-range ordering but at the same time generated thicker pore walls. The ove…
A significant enhancement in the performance of a ZnO nanowire-based UV detector has been achieved through fabricating a Ag/ZnO heterostructure by a photoreduction reaction. This enhancement is due to a Schottky barrier at the interface of Ag and ZnO because of the formation of a thin AgO x layer. An efficient and low…
Nickel nanowires have been formed by stationary electrochemical deposition of nickel into mesoporous silicon templates from the modified Watts bath. Monitoring of the porous silicon potential during the electrochemical deposition has given the determination of the emergence of Ni on the outer surface of porous layer.…
Quartz dissolves in Na+ solutions much faster than in pure water though the experimental activation energies are essentially the same. To elucidate the mechanism, silica dissolution was simulated using Gaussian 03 software at B3LYP/3-21G* initially and the B3LYP/6-311G(2d,p) levels, applied to a modeled silica Si4O6(O…
The renewable, biodegradable polymer polylactide (PLA) has been employed in biomedical applications, and its use is becoming more common within various commercial packaging materials. Architectural diversity within this class of polymers, however, is still somewhat limited; which, in turn, limits the properties of thi…
In the present work, the dealloying of Al–Au-based precursors and formation of nanoporous Au-based alloys have been investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) and energy dispersive X-ray (EDX) analysis. The results…
Three series of bent-shaped compounds containing the 1,2,3-triazole ring in the central core of the molecule have been prepared by the most extended “click chemistry” reaction, the copper-catalyzed azide-alkyne cycloaddition (CuAAC). This research demonstrates the versatility of this synthetic approach with the aim of…
In a previous paper, we proposed new silver nanoparticles (SNPs) based antibacterial coatings able to protect eukaryotic cells from SNPs related toxic effects, while preserving antibacterial efficiency. A SNPs containing n‐heptylamine (HA) polymer matrix was deposited by plasma polymerization and coated by a second HA…
We have developed an amplified chemiluminescence turn-on sensing platform that relies on single-walled carbon nanotubes for ultrasensitive DNA detection. This new type of assay exhibits higher detection sensitivity over traditional biosensors by three orders of magnitude and high specificity for the target molecules.
