Microcapsulation of phase change materials (PCMs) within a shell is one of the most feasible methods to explore their applications for thermal energy storage. Here, a facile method to microencapsulate PCMs within polystyrene/cellulose nanocrystal (CNC) hybrid shell via Pickering emulsion polymerization was developed.…
Abstract The rapid development of miniature electronics has accelerated the demand for simplified and scalable production of micro‐supercapacitors (MSCs); however, the preparation of active materials, patterning microelectrodes, and subsequent modular integration of the reported MSCs are normally separated and are inv…
Two methods-attenuated total reflection Fourier infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS)-have been used to analyze the chemical structure of polytetrafluorethylene (PTFE) thin coatings deposited by pulsed laser (PLD) and pulsed electron beam (PED) ablations. The volume of the analyze…
As a promising ultra-wide bandgap semiconductor, the β-phase of Ga2O3has attracted more and more interest in the field of power electronics due to its ultra-wide bandgap (4.8 eV), high theoretical breakdown electric field (8 MV/cm), and large Baliga's figure of merit, which is deemed as a potential candidate for next…
Single-molecule magnets (SMMs) are at the forefront of new technological advances in quantum information processing and spintronics. Despite the recent impressive breakthroughs in extending the magnetic blocking temperatures beyond liquid-nitrogen temperatures, significant challenges await in terms of integrating and…
Surface capping agents have been extensively used to control the evolution of seeds into nanocrystals with diverse but well-controlled shapes. Here we offer a comprehensive review of these agents, with a focus on the mechanistic understanding of their roles in guiding the shape evolution of metal nanocrystals. We begi…
Abstract The effect of BN nanodots with hexagonal shape on the electronic properties of α- and β-graphyne sheets is investigated. The structural and electronic properties of α- and β-graphyne sheets doped with BN nanodots are studied by using density functional theory. The cohesive energies of the systems indicate all…
The electron spin resonance (ESR) and electron nuclear double resonance (ENDOR) spectroscopies are frequently used to determine hyperfine ( A ) and quadrupole ( Q ) tensors for the paramagnetic transition-metal complexes, which knowledge enables estimation of the spin density distribution in the complex and the assess…
ABSTRACT The effect of several mixing process parameters on the concentration of carbon black particles at the interface between the polymer components in polyethylene–polystyrene mixtures was studied. It was established that the process of particle transport from the polymer phase to the interface happens only under…
ZnGa 2−x In x O 4 : Cr 3+ (1.0 mol%) (x = 0, 0.02, 0.04, 0.06, 0.08, 1.0 and 2.0) nano-powders were synthesized by using the sol gel method. The x-ray diffraction (XRD) results confirmed that the prepared ZnGa 2−x In x O 4 : Cr 3+ samples were cubic in structure. The calculated average crystallite size has values of,…
With the rapid development of science and technology, especially the fast progress in the radar detection technology, lots of efforts have been made to obtain high performance microwave absorption materials. In recent years, carbon-based microwave absorption materials have received much attention because of their high…
Nano drug co-delivery system is a popular strategy for combined application of two or more anticancer and/or synergistic drugs. Synergistic effects of nonsteroidal anti-inflammatory drugs and anti-cancer drugs in cancer treatment are shown in the literature. This study aimed to screen and understand the critical formu…
Abstract Understanding the effect of physical parameters (e.g., temperature) on crystallisation dynamics is of paramount importance for the synthesis of nanocrystals of well‐defined sizes and geometries. However, imaging nucleation and growth is an experimental challenge owing to the resolution required and the kineti…
Abstract We investigated the temperature dependence of the spin-to-charge current conversion at nonmagnetic metal (NM: Cu or Ag)/Bi 2 O 3 interfaces with Rashba spin-splitting. Spin pumping induced inverse Edelstein effects are measured in the temperature range from 290 K to 10 K. Estimated conversion coefficients at…

The surface discharge along the interface of solid–liquid insulation is one of the main causes of the deterioration of the life of a power transformer. This experimental study investigates the effects of different solid and liquid insulation materials on the surface partial discharge (PD) characteristics. The liquid i…
Abstract Facet‐dependent on‐surface reactions are systematically studied on zinc‐blende CdSe nanoplatelets with atomically‐flat {001} basal facets and small yet non‐polar side facets. The on‐surface half‐reactions between the surface Se sites and Cd carboxylates in the solution are qualitatively equivalent to those on…
Abstract Nanogele haben sich aufgrund ihrer erstrebenswerten physikochemischen Eigenschaften und vielseitigen Anwendbarkeit auf diverse therapeutische Moleküle und bildgebende Sonden als herausragende Kandidaten für Nanocarrier zur Wirkstoffabgabe herausgestellt. Eine der zentralen Herausforderungen, welche die klinis…
A low-temperature sol-gel Ga-doped ZnO (ZnO:Ga) thin film as the electron transport layer (ETL) for high efficiency inverted polymer solar cells (PSCs) has been realised. The ZnO:Ga precursor was prepared by dissolving zinc acetate and ethanolamine in the 2-methoxyethanol with Ga(NO3)3 at different concentration. Dope…
We propose a planar THz hybrid bulk Dirac semimetal (BDS)-metal metamaterial which consists of a hybrid BDS-metal array on a dielectric layer and a back metallic mirror. The simulation results show that a spectral window that possesses high reflectance with no polarization conversion effect arises in the polarization…
