Recently, increasing attention has been paid to development of new functional materials for the environment and health, due to the huge waste produced annually by the shellfish processing industry and the absence of waste management which lead to environmental and human health negative effects. The extraction of chiti…
In this study, the properties of molded ramie fibers reinforced with polylactic acid (PLA) biocomposites were investigated. Before preparation of composites, diammonium phosphate (DAP) was applied to the surface of ramie fibers with and without pretreatments to analyze the interfacial adhesion of ramie–PLA composite.…
We present single photon sources (SPSs) embedded in 4H-SiC metal-oxide-semiconductor field-effect transistors (MOSFETs). They are formed in the SiC/SiO2 interface regions of wet-oxidation C-face 4H-SiC MOSFETs and were not found in other C-face and Si-face MOSFETs. Their bright room-temperature photoluminescence (PL)…
Probing the chemical space of luminescent organic materials built on novel cores is highly imperative for its potential to expand the horizons of advanced functional materials. Small organic fluorophores possessing therapeutic traits can contribute to theranostics. We coupled computational and classical synthetic chem…
Understanding the physical mechanisms of the refractive index modulation induced by femtosecond laser writing is crucial for tailoring the properties of the resulting optical waveguides. In this work, we apply polarized Raman spectroscopy to study the origin of stress-induced waveguides in diamond, produced by femtose…
Luminescent molecules with aggregation-induced emission (AIE) property or AIE-active luminogens (AIE-gens) are typical stimuli-responsive materials. Many AIE-gens have shown luminescent responses to mechano-, thermo-, electro-, vapo-, and/or solvato-stimulus, but the detailed structure-property relationship has been a…
Abstract Using non-equilibrium molecular dynamics simulations, we investigate thermal rectification (TR) in graphene/hexagonal boron nitride (h-BN) hybrid structures. Two different structural models, partially substituting graphene into h-BN (CBN) and partially substituting h-BN into graphene (BNC), are considered. It…
Abstract Aqueous electrochemical energy storages are of enormous attention due to their high safety and being environmentally friendly, but they must satisfy very challenging standards in energy and power densities over long repeated charging/discharging cycles. Herein, a strategy to realize high‐performance aqueous h…
Waterborne polyurethane (WBPU)/cerium nitrate (Ce(NO3)3) dispersions were synthesized with different defined Ce(NO3)3 content. All pristine dispersions were stable with different poly(tetramethylene oxide) glycol (PTMG) number average molecular weights (Mn) of 650, 1000, and 2000. The interaction between the carboxyl…
The temperature and pH dependent self-assembly of three star shaped ethylene oxide-propylene oxide (EO-PO) block copolymers (Tetronics® 304, 904 and 908) with widely different hydrophobicity was examined in aqueous solutions. Physico-chemical methods viz. viscosity, cloud point, solubilization along with thermal, scat…
Abstract 2D layered materials (2DLMs), together with their heterostructures, have been attracting tremendous research interest in recent years because of their unique physical and electrical properties. A variety of circuit elements have been made using mechanically exfoliated 2DLMs recently, including hard drives, de…
Abstract Shell‐isolated nanoparticles (SHINs) composed of a protective shell and a plasmonic metal core have been extensively used in plasmon‐enhanced Raman and fluorescence spectroscopy. Whereby, SHIN‐enhanced Raman spectroscopy has effectively overcome the material and morphology limitations for traditional surface‐…
Herein 2,3-dialdehyde cellulose beads prepared from Cladophora green algae nanocellulose were sulfonated and characterized by FTIR, conductometric titration, elemental analysis, SEM, ζ-potential, nitrogen adsorption–desorption and laser diffraction, aiming for its application as a potential immunosorbent material. Por…
The sensitivity of magnetic resonance imaging (MRI) is dictated by the signal-to-noise ratio. It was recently noted that the signal-to-noise ratio could be substantially increased via excitation of certain metasurface eigenmodes. Here, we provide a detailed discussion of the wire metasurface eigenmode impact on the se…
The effect of La dopant concentration (4% and 6%) and annealing (400, 600 and 800 °C) behavior of CuO derived by solution combustion method (SCS) are investigated. Structural and optical properties were studied by XRD, SEM, diffuse reflectance spectra (DRS) and photoluminescence (PL) measurements for the prepared samp…
Perovskite BiFeO 3 nanoplates were prepared via a facile hydrothermal method with NaOH as mineralizer. The obtained BiFeO 3 nanoplates are about 30[Formula: see text]nm [Formula: see text] 90[Formula: see text]nm [Formula: see text]90[Formula: see text]nm in an average shape. This hydrothermal novel nanostructure with…
Abstract Magnetic cooling technology based on magnetocaloric effect (MCE) has attracted great interest in obtaining extremely low temperatures, for example, for space exploration. Here, we grew a new gadolinium‐rich orthoborate K 3 Li 3 Gd 7 (BO 3 ) 9 ( 1 ) as a promising cryogenic magnetic coolant. It exhibits a comp…
The study of nucleation and growth from supersaturated ion solutions is a key area of interest in biomineralization research and beyond with high-resolution in situ imaging techniques such as liquid cell transmission electron microscopy (LCTEM) attracting substantial attention. However, there is increasing experimenta…
This paper reports a compact spectrometer based on a guided-mode resonance (GMR) filter mounted on a linear charge-coupled device (CCD). The GMR is specially designed to exhibit gradient grating periods (GPPs) laterally to ensure that the GMR functions as a linear-variable bandstop filter. Each period corresponds to a…
Cancer chemotherapeutic systems with high antitumor effects and less adverse effects are eagerly desired. Here, a pH-sensitive delivery system for bleomycin (BLM) was developed using egg yolk phosphatidylcholine liposomes modified with poly(ethylene glycol)-lipid (PEG-PE) for long circulation in the bloodstream and 2-…
