This paper investigates Phyllanthus muellerianus leaf-extract effects on steel-reinforcement corrosion in concrete immersed in 3.5% NaCl, simulating saline/marine environment. Different concentrations of the leaf-extract were admixed in steel-reinforced concrete samples, which were immersed, with normal control, in th…
The structure, stability, and reorganization of lamella-forming block copolymer thin film surface topography (“islands” and “holes”) were studied under boundary conditions driving the formation of 0.5 L 0 thick structures at short thermal annealing times. Self-consistent field theory predicts that the presence of one…
Hierarchically heterostructured hollow spheres are of great interest for a wide range of applications owing to their unique structural features and properties. However, the fabrication of well-defined hollow spheres with highly specific morphology for mixed transition metal oxides on a large scale remains challenging.…
, synthesized by high pressure and high temperature. First-principle calculation combined with X-ray photoelectron spectrum unravel that the honeycomb boron structure was stabilized by filling the empty π-band via grabbing electrons from manganese layers. Honeycomb boron layers sandwiching manganese layers is an extra…
Studies on magnetoliposomes (MLUV) as potential carriers for magnetic-field-dependent drug delivery are presented. The systems were formed with hydrophobic superparamagnetic iron oxide nanoparticles (SPIONs) confined within the bilayer of the liposomes. The nanomechanical properties of bilayer lipid membranes were eva…
Abstract Photoinduced syntheses offer significant advantages over conventional thermal strategies, including improved control over reaction kinetics and low synthesis temperatures, affording nanoparticles with nontrivial and thermodynamically unstable structures. However, the photoinduced syntheses of non‐metallic nan…
Nucleation and growth of the Mg–Al layered double hydroxide nanoparticles are controlled by varying the nucleation temperature in conjunction with a fast addition of metal precursor solution. Nanoparticles of the size between 20 and 200 nm are obtained, while avoiding the use of organic structure directing agents and…
The application of functionalized nanocarriers on photothermal therapy for cancer ablation has wide interest. The success of this application depends on the therapeutic efficiency and biocompatibility of the system, but also on the stability and biorecognition of the conjugated protein. This study aims at investigatin…
AIM: To develop a seminal enzyme bioresponsive, mucoadhesive nanofibers (NFs) as safe and effective nanocarriers for the prevention of HIV vaginal transmission. METHODS: A novel thiolated hyaluronic acid (HA-SH) polymer was synthesized to fabricate tenofovir (TFV)-loaded electrospun NFs (HA-SH-NFs) and characterized i…
Calcium silicate hydrate and its Al‐substituted form synthesized by a hydrothermal process were investigated by X‐ray diffraction, compositional analysis, and magic‐angle spinning nuclear magnetic resonance ( MAS NMR ) spectroscopy, in order to determine the mechanism of Al and Na incorporation in the tobermorite stru…
AIM: This work compares the synthesis, heating capability, cellular internalization and thermoablation capacity of two different types of anisotropic gold nanoparticles: gold nanorods (NRs) and nanoprisms (NPrs). METHODS: Both particles possess surface plasmon resonance absorption bands in the near-IR, and their heati…
Carbon quantum dots (CQDs) are a new type of fluorescent nanoparticle for cell imaging and tracking. However, they would easily diffuse and quench, followed by the loss of their fluorescence ability. By connecting their functional groups with other nanoparticles, the CQDs will be protected from destruction and exhibit…
Widely available vegetable oils were readily derivatized into chemically pure AB <sub>n</sub> -type monomers ( <italic>n</italic> = 2 or 3).
The United Kingdom holds the largest stockpile of separated civil plutonium in the world, projected to reach 140 t, at the end of this decade, when reprocessing operations are complete. UK Government policy is that this material should be reused as MOX fuel in Light Water Reactors. This policy is re-examined in the li…
Abstract Silver nanoparticles (AgNPs) are widely used in numerous industries and areas of daily life, mainly as antimicrobial agents. The particles size is very important, but still not suffi ciently recognized parameter infl uencing the toxicity of nanosilver. The aim of this study was to investigate the cytotoxic ef…
We report simultaneous transport and scanning microwave impedance microscopy to examine the correlation between transport quantization and filling of the bulk Landau levels in the quantum Hall regime in gated graphene devices. Surprisingly, a comparison of these measurements reveals that quantized transport typically…
Facile synthetic routes to a new class of red α-benzo-fused BOPHYs with 6,5,6,6,5,6-hexacyclic fused rings and β-thiophene-fused BOPHYs with 5,5,6,6,5,5-hexacyclic fused rings are presented. These dyes were characterized by NMR spectroscopy, HRMS, X-ray structure analysis, cyclic voltammetry, and optical measurements.…
The polyethyleneimine (PEI) microgels prepared via microemulsion polymerization are protonated by hydrochloric acid treatment (p-PEI) and quaternized (q-PEI) via modification reaction with methyl iodide and with bromo alkanes of different alkyl chain lengths such as 1-bromoethane, 1-bromobutane, 1-bromohexane, and 1-b…
Palladium nanoparticles (Pd NPs) were synthesized by the reduction-by-solvent method using polyvinylpirrolidone (PVP) as capping agent. The nonstatic interaction between PVP and the metallic surface may change the properties of the NPs due to the different possible interactions, through either the O or N atoms of the…
Biopolymer-based composites enable to combine different functionalities using renewable materials and cost-effective routes. Here we fabricate novel thermoresponsive photonic films combining cellulose nanocrystals (CNCs) with a polydiolcitrate elastomer exhibiting shape memory properties, known as hydroxyl-dominant po…
