Recently, several researches have focused on the study of the photocatalytic performance of nanoparticles in concretes and cements. This paper evaluates the photocatalytic activity of Zn-Al-Ti nanoparticles as well as the mineralogical behavior of clinker pastes with the addition of those particles. The samples were i…
Phenylenediamine (PDA) was chosen as a coordinating, reducing, and capping agent to effectively direct growth and protect against oxidation of Cu nanowires (Cu NWs) in an aqueous solution. PDA was found to reduce Cu (II) to Cu (I) at room temperature, and stabilize the resulting Cu (I) by forming a coordination comple…
Abstract A most used structural material, mild steel which is prone to catastrophic failure is studied to enhance the surface properties with the application of NiTi using atmospheric plasma spray (APS) technique. Near equiatomic Ni-Ti composition is popular for its shape memory effect and superelastic behaviour. In t…
Ultrafine and uniformly dispersed bimetallic Pt–Ni nanoparticles (NPs) have been immobilized on novel 3-dimensional N-doped graphene networks (NGNs) by a facile wet chemical reduction method, which exhibit extremely high catalytic activity for the dehydrogenation of hydrazine hydrate.
Magnetic nanoparticles have had a significant impact on a wide range of advanced applications in the academic and industrial fields. In particular, in nanomedicine, the nanoparticles require specific properties, including hydrophilic behavior, uniform and tunable dimensions, and good magnetic properties, which are sti…
First principles-based mesoscale characterization of electron transport in W/Mo-doped BiVO 4 reveals the existence of “stabilization” regions around dopant sites. The stabilization regions decrease slightly the electron polaron mobility, albeit the overall electrode conductivity increases.
Enzymes are highly advantageous compared to dew retting to reach fibers of high and consistent quality. However, no unambiguous insights have been retained from the research, i.e. lacking a clear directive of which enzyme activities are strictly needed. Methods for evaluating enzymatic retting should be standardized,…
This feature article provides both a critical perspective as to where synthetic 2D polymers currently stand and a rather substantial view into how the future of this exciting field of polymer chemistry might look. It starts out by addressing strategic considerations meant to familiarize the reader with what to expect…
There is a growing need for biocompatible nanocomposites that may efficiently interact with biological tissues through multiple modalities. Carbon dots (CDs) could serve as biocompatible fluorescence nanomaterials for targeted tissue/cell imaging. Important goals toward this end are to enhance the fluorescence quantum…
Graphene quantum dot (GQD) encapsulated melamine-formaldehyde (MF) polymer microspheres with uniform particle size and tunable high-quality white-light emissions are prepared via a polymer-mediated GQD assembly and encapsulation strategy. In solution, GQDs are first aggregated with MF prepolymer through electrostatic…
Spherical nanoparticles of zinc oxide (ZnO NPs) were synthesized by an eco-friendly green combustion method using citrate containing Artocarpus gomezianus fruit extract as a fuel. The morphology, compositions and structure of the product were characterized by Powder X-ray Diffraction (PXRD), Scanning Electron Microsco…
Glass systems of composition 16XO–3Al 2 O 3 –6CuO–20Na 2 O–55P 2 O 5 (where X = Sr, Ca, Mg and Ba mol%) have been investigated to check its potential utilize as gamma ray shielding material. Different shielding quantities namely mass attenuation coefficient (µ/ρ), effective atomic number (Z eff ), half value layer (HV…
Ti 3 C 2 , though one of the most extensively studied 2D MXenes, is rarely reported in dye-sensitized photocatalysis.
nitrogen-doped carbon) does not affect the catalytic response, but determines the deactivation mechanism (gold particle aggregation and pore blockage, respectively), which opens up different options for the development of stable, high-performance hydrochlorination catalysts.
Matrix metalloproteinase-7 plays a pivotal role in tumour progression and metastasis as an enzyme that can degrade the cell-matrix composition and cleave peptides between alanine and leucine in various biomolecular activation processes. In this work, a Pd-functionalised carbon nanocomposite was designed as a new imped…
The Sc 2 O 3 : Er 3+ , Yb 3+ nanoparticles (NPs) with the size of about 19 nm were synthesized by a simple oleic acid-mediated hydrothermal (HT) process. X-ray diffraction (XRD), transmission electron microscopy (TEM), upconversion luminescence (UCL) spectra, and decay curves were used to characterize the resulting sa…
Hydrogenated graphene (HG)/hexagonal boron nitride (h-BN) heterobilayer is an ideal structure for the high-performance field effect transistor. In this paper, the carrier mobilities of HG/h-BN heterobilayer are investigated based on the first-principles calculations by considering the influence of stacking pattern bet…
In this study, energetic Al/Ni superlattice was deposited by magnetron sputtering. A micro-plasma generator was fabricated using the energetic Al/Ni superlattice. The cross-sectional micro-structure of the energetic Al/Ni superlattice was scanned by transmission electron microscopy. Results show that the superlattice…
New drug treatments still do not improve the prognosis of extramedullary multiple myeloma (EMM) patients. Luckily, high-dose chemotherapy can raise the prognosis, but is intolerant to most patients because of drug cytotoxicity. Nanoparticles (NPs) are used as drug carriers to prolong drug circulation time, control dru…
Despite being the archetypal thermoelectric material, still today some of the most exciting advances in the efficiency of these materials are being achieved by tuning the properties of PbTe. Its inherently low lattice thermal conductivity can be lowered to its fundamental limit by designing a structure capable of scat…
