In recently developed non-fullerene acceptor (NFA) based organic solar cells (OSCs), both the donor and acceptor parts can be excited by absorbing light photons. Therefore, both the electron transfer and hole transfer channels could occur at the donor/acceptor interface for generating free charge carriers in NFA based…
Hydrogen can penetrate reversibly a number of metals, occupy the interstitial sites and cause large expansion of the crystal lattice. The question discussed here is whether the kinetics of the structural response matches hydrogen absorption. We show that thin Pd and CoPd films exposed to a relatively rich hydrogen atm…
Based on the first-principles calculations and theoretical analysis, we investigate the electronic structures, topological phase transition (TPT), and topological properties of the layered magnetic compound ${\mathrm{MnSb}}_{2}{\mathrm{Te}}_{4}$. We have synthesized a ${\mathrm{MnSb}}_{2}{\mathrm{Te}}_{4}$ sample and…
We present a study of the dielectric, structural, and magnetic properties of the multiferroic or linear magnetoelectric substitution series ${[{({\mathrm{NH}}_{4})}_{1\ensuremath{-}x}{\mathrm{K}}_{x}]}_{2}[\mathrm{Fe}{\mathrm{Cl}}_{5}({\mathrm{H}}_{2}\mathrm{O})]$. Pyroelectric currents, magnetic susceptibilities, and…
Using a multiscale computational approach, we probe the origin and evolution of ultraflat bands in moir\'e superlattices of twisted bilayer $\mathrm{Mo}{\mathrm{S}}_{2}$, a prototypical transition metal dichalcogenide. Unlike twisted bilayer graphene, we find no unique magic angles in twisted bilayer $\mathrm{Mo}{\mat…
We report the temperature and pressure (pmax ≃ 1.5 GPa) evolution of the crystal structure of the Weyl semimetal Td-MoTe2 by combination of neutron diffraction and the X-ray total scattering experiments. We find that the fundamental non-centrosymmetric structure Td is fully suppressed and transforms into a centrosymme…
Bismuth telluride is a widely explored material in the condensed matter community and one of the first experimentally identified as a topological insulator. Nevertheless, despite considerable effort, the bulk electronic band structure of Bi${}_{2}$Te${}_{3}$ is known only partially. Here, the authors present a magneto…
FeNi L10 (tetrataenite) phase has great perspectives for hard magnetic materials production. In this paper it was synthesized in chemically co-precipitated FeNi nanopowder by means of thermal treating included cycling of oxidation and reduction processes at 320 °C. The presence of FeNi L10 phase in the samples was con…
We fabricate AlGaN nanowires by molecular beam epitaxy and we investigate their field emission properties by means of an experimental setup using nano-manipulated tungsten tips as electrodes, inside a scanning electron microscope. The tip-shaped anode gives access to local properties and allows collecting electrons em…
Manganese dioxide (MnO2) nanosheets have shown exciting potential in nanomedicine because of their ultrathin thickness, large surface area, high near-infrared (NIR) absorbance and good biocompatibility. However, the effect of MnO2 nanosheets on bacteria is still unclear. In this study, MnO2 nanosheets were shown for t…
Using reverse thinking of the aggregation-induced emission (AIE) principle, we demonstrate an ingenious and universal protocol for amplifying molecular motions to boost photothermal efficiency of fibers. Core-shell nanofibers having the olive oil solution of AIE-active molecules as the core surrounded by PVDF-HFP shel…
The study highlights effectiveness of hydrodynamic cavitation (HC) in the degradation of effluents polluted by Brilliant Cresyl Blue (BCB) dye. Optimal process parameters were cavitation number 0.27, inlet pressure 1.70 bar, temperature 20 °C and pH 7. The efficiency of HC was investigated in combination with other ad…
The current knowledge about the formation of layer-by-layer (LbL) self-assemblies using combinations of nanocelluloses (NCs) and polyelectrolytes is reviewed. Herein, the fundamentals behind the LbL formation, with a major focus on NCs, are considered. Following this, a special description of the limiting factors for…
Two-dimensional graphene-based van der Waals heterostructures have received considerable interest because of their intriguing characteristics compared with the constituent single-layer two-dimensional materials. Here, we investigate the interfacial characteristics, Schottky contact, and optical performance of $\mathrm…
Many monumental breakthroughs in p -type PbTe thermoelectrics are driven by optimizing a Pb 0.98 Na 0.02 Te matrix. However, recent works found that x > 0.02 in Pb 1– x Na x Te further improves the thermoelectric figure of merit, zT, despite being above the expected Na solubility limit. We explain the origins of impro…
Polymeric nanoparticles are one of the most studied strategies in modern medicine for drug encapsulation. The researchers' main interest is a formulation capable of administering the medication in a controlled mode and specific site. In this context, stimulus-responsive nanoparticles are highlighted, as these systems…
Sepsis is an aberrant systemic inflammatory response mediated by excessive production of reactive oxygen species (ROS) and reactive nitrogen species (RNS). Developing an efficient antioxidant therapy for sepsis via scavenging ROS and RNS remains a big challenge owing to the insufficient activity and sustainability of…
Abstract Hydrogen is an ideal energy carrier in future applications due to clean byproducts and high efficiency. However, many challenges remain in the application of hydrogen, including hydrogen production, delivery, storage and conversion. In terms of hydrogen storage, two compression modes (mechanical and non-mecha…
Photothermal therapy (PTT), an emerging tumor treatment technology, has attracted tremendous interest, but excessive heat will cause damage to surrounding healthy tissues. Therefore, in situ temperature monitoring during PTT is of great importance to determine optimal treatment temperature and repair heat-damaged norm…
Abstract Optical transparency is an important property for a material, especially in certain fields like packaging, glazing, and displays. Existing commercial transparent polymeric materials are mostly amorphous. Semicrystalline polymers have often‐superior chemical resistance and mechanical properties particularly at…
