Lack of directional bonding between two-dimensional crystals like graphene or monolayer transition metal dichalcogenides provides unusual freedom in the selection of components for vertical van der Waals heterostructures. However, even for identical layers, their stacking, in particular the relative angle between thei…
We propose a hypothesis that the potential energy surface (PES) of interlayer interaction in diverse 2D materials can be universally described by the first spatial Fourier harmonics. This statement (checked previously for the interactions between graphene and hexagonal boron nitride layers in different combinations) i…
Abstract The hot‐deformed magnets processed from nanocrystalline/amorphous Nd–Fe–B powders were prepared under different hot‐pressing temperatures (600–750 °C, at intervals of 25 °C) by the self‐made hot‐pressing equipment. The microstructure and magnetic properties of hot‐deformed magnets prepared at different temper…
The use of metal-containing nanoparticles capable of localized surface plasmon resonance (LSPR)-enhanced singlet oxygen ( 1 O 2 ) production, via photosensitization, are currently promising candidates for cytotoxic medical purposes. Despite the ongoing advances in fabricating plasmonic nanomaterials, much of the insig…
The mechanical and physical properties of Mg-Ca alloys make them suitable for temporary orthopaedic implant applications. However, the rapid degradation of these alloys limits their use in the physiological environment. The effect of calcium phosphate (CaP) coating on biomineralization, biodegradation, and mechanical…
A commercial low-density polyethylene (LDPE) which is produced by the polymerization process of ethylene in the presence of initiators in a long tubular reactor is the most widely used in polymer industry. The highly exothermic nature of the LDPE polymerization process and the heating-cooling prerequisite in the tubul…
Enhancing the electromechanical response by engineering domain boundaries in multiferroics has become a highly active research field in recent years. The starting point is the discovery that ferroelastic twin walls are polar inside a nonpolar matrix. The density of such twin walls is then greatly enhanced by forming c…
Abstract The growth of graphite on polycrystalline Ni by chemical vapor deposition (CVD) and the microstructural relation of the graphitic films and the metallic substrate continues to puzzle the scientific community. Here, we report the wafer-scale growth of a nanometer-thick graphite film (∼100 nm, NGF) on Ni foil v…
Bulk, solventless anionic ring-opening polymerization (AROP) of ε-caprolactam (CPL) with high yields, without side products and with short reaction times, initiated by caprolactamate-carbamoylcaprolactam initiating systems belong to green polymerization processes, leading to poly(ε-caprolactam) (Polyamide 6, PA6, Nylo…
Three-dimensional scaffolds play an essential role in tissue engineering. Although essential, the tunability of the 3D scaffolds mechanical and transport properties remains a challenge. In this work, we present new approaches to advance the field. First, we applied our progressive pH acidification to mimic the natural…
Even though silver and silver nanoparticles at low concentrations are considered safe for human health, their steadily increasing use and associated release in nature is not without risk since it may result in the selection of silver-resistant microorganisms, thus impeding the utilization of silver as antimicrobial ag…
Recent experiments in unconventional superconductors, and in particular iron-based materials, have reported evidence of an antiferromagnetic quantum critical point (AFM-QCP) emerging inside the superconducting dome of the phase diagram. Fluctuations associated with such an AFM-QCP are expected to promote unusual tempe…
Abstract Herein, the amino‐acid based glycine (Gly) solubility in different solvents (ethanol, pyridine, and n‐hexane) exhibited striking interlocking behavior with mesoporous silica nanoparticles (MP‐SiO 2 NPs) has been reported and discussed in detail. The synthesis of MP‐SiO 2 NPs carried out employing the modified…
Abstract The inner ear of the rainbow trout contains biominerals called otoliths that are composed of calcium carbonate crystals and a protein organic matrix. The organic matrix macromolecule-64 (OMM-64) is an intrinsically disordered protein associated with high-molecular-weight aggregates. In this study, through a s…
Abstract In the current work, silica‐decorated graphene oxide (SiO2@GONPs) nanohybrids were used to reinforce the jute fiber/epoxy (JF/EP) composite. Tetraethylorthosilicate (TEOS) was utilized to prepare the SiO2@GONPs using a facial route. The results of Fourier‐transform infrared spectroscopy (FTIR), atomic force m…
Herein, phase formation and sintering of hafnium carbonitride ceramics from a 4HfC–3HfN powder mixture using reactive spark plasma sintering are studied. X‐ray diffraction (XRD) data show that the mutual heterodiffusion of carbon C and nitrogen N increases with sintering temperature within the studied temperature rang…
Adsorption of poly(amido amine) dendrimers (G8 generation) on silica substrates was studied by atomic force microscopy (AFM), quartz crystal microbalance (QCM), and optical waveguide lightmode spectroscopy (OWLS). Initially, diffusion coefficient, hydrodynamic diameter, electrophoretic mobility, and stability of the d…
Slow evaporation method was used to grow the pure and K+ ion doped L-Lysine monohydrochloride (L-LMHCL) crystals which has optical and antibiotic applications. The space group, structure and slight shifting of peaks are confirmed using single crystal XRD and the powder XRD. The FTIR analysis also shows that the K+ dop…
Objective: The study is to explore the effect of stannic oxide nanoparticle (SnO2 NP) on proliferation, invasion, apoptosis, and oxidative stress of oral cancer. Methods: The absorption characteristics, X-ray diffraction (XRD) pattern, and transmission electron microscopy (TEM) image of SnO2 NP were measured. The effe…
Abstract A series of 3,7-bis(arylethynyl)-substituted phenothiazine-based fluorophores (bearing benzene, naphthalene, methoxynaphthalene, anthracene, phenanthrene, and pyrene) were designed and synthesized via a Pd-catalyzed Sonogashira cross-coupling reaction. These molecules show in solution large Stokes shifts (ge…
