Abstract Q-carbon is a metastable phase of carbon formed by melting and subsequently quenching amorphous carbon films by a nanosecond laser in a super undercooled state. As Q-carbon is a material harder than diamond, it makes an excellent reinforcing component inside the softer matrix of a composite coating. In this r…

The Ir III hydride ( t Bu PCN)IrHCl ( 1 ) containing the tridendate unsymmetrical pincer ligand t Bu PCN – { t Bu PCN(H) = 1-[3-[(di- tert -butylphosphino)methyl]phenyl]-1 H -pyrazole} has been exploited as ammonia borane (NH 3 BH 3, AB) and amine boranes dehydrogenation catalyst in THF solution at ambient temperature…
Abstract Advanced materials with low density and high strength impose transformative impacts in the construction, aerospace, and automobile industries. These materials can be realized by assembling well‐designed modular building units (BUs) into interconnected structures. This study uses a hierarchical design strategy…
This study reports a green synthesis route for a bilayered Ag-MgO nanocomposite using aqueous peel extract of Citrus paradisi (grapefruit red) under an accelerated uniform heating technique and its antibacterial potency against Escherichia coli . Surface modifications and composition of the nanocomposite were examined…
Polyion complex vesicles (PICsomes) formed from a self-assembly of an oppositely charged pair of block- and homo-polyelectrolytes have shown exceptional features for functional loading of bioactive agents. Nevertheless, the stability of PICsomes is often jeopardized in a physiological environment, and only PICsomes ha…
Biofouling on silicone implants causes serious complications such as fibrotic encapsulation, bacterial infection, and implant failure. Here we report the development of antifouling, antibacterial silicones through covalent grafting with a cell-membrane-inspired zwitterionic gel layer composed of 2-methacryolyl phospho…
Achieving red phosphorescence from purely organic system is a challenging feat due to the predominant thermal nonradiative decay pathways of the excited electrons. Here, we design single-component charge-transfer (CT) complexes based on phenoxazine–quinoline conjugates ( PQ1 – PQ3 ), in which the phenoxazine ring is c…
BACKGROUND: Silver nanoparticles (AgNPs) are more often used in various products, and consequently the potential deleterious effects associated with exposure to them are of concern. Several lines of evidence have demonstrated that the toxicity of AgNPs affects different organs and leads to some side effects, including…
The unique property of plasmonic materials to localize light into deep sub-wavelength regime has greatly driven various applications in the field of photovoltaics, sensors, and photocatalysis. Here, we demonstrate the one-step growth of an oxide–metal hybrid thin film incorporating well-dispersed gold (Au) nanoparticl…
Cellulose fiber was isolated from bengkoang (Pachyrhizus erosus) tuber peel. A suspension consisting of distilled water, starch, and glycerol was mixed with various cellulose loadings (0, 2, 6, and 10 g) then gelatinized using a hot plate with a magnetic stirrer. The biocomposite gel was sonicated using an ultrasonica…
NS composite was designed for all-solid-state flexible supercapacitors with a high specific capacitance, moderate cycle stability and good mechanical flexibility, indicating a promising application in flexible supercapacitors.
Emerging antibiotic resistance necessitates the development of new therapeutic approaches. Many studies have reported the antimicrobial activity of diclofenac sodium (DIC) and chitosan nanoparticles (CNPs). Hence, this study aimed to prepare non-antibiotic DIC-loaded CNPs (DIC.CNPs) and characterize their in vitro ant…
Processability has always been a challenge for most insoluble porous materials. Herein, we report a facile approach to realize their processability by physically blending them into a thiol-containing polysiloxane matrix (PMMS) followed by an efficient thiol–ene cross-linking reaction, resulting in novel silicone elast…
Thermoplastic polyurethane (TPU) composites filled with fullerene in the range from 0.5 wt% to 2 wt% were fabricated using melt-compounding. Fullerene addition levels up to nearly twofold increase in tensile strength, percent elongation, and modulus of TPU. The mechanical properties are improved as modified C 60 conte…
A novel, non-radiative mechanism is reported by which Frenkel pairs of vacancies and interstitials are generated in molar concentrations far above thermal equilibrium. This mechanism is demonstrated in molecular dynamics (MD) simulations of an aluminum single crystal with a free surface. They suggest that three condit…
The catalytic oxidation of CO on Cu 3 -cluster-decorated pristine and defective Mo 2 CO 2 (MXene) monolayers (Cu 3 /p-Mo 2 CO 2 and Cu 3 /d-Mo 2 CO 2 ) was investigated by first-principles calculations. The stability of the designed catalysts was comprehensively demonstrated via analysis of the energies, geometry dist…
Abstract Defects have crucial effects on the electronic and optoelectronic properties of two‐dimensional materials. In this work, we measured the changes in the Raman spectra and electrical conductance of monolayer molybdenum disulfide (MoS 2 ) with increasing defects via thermal annealing in a reducing atmosphere. Ra…
Constructing segregated structure in conductive polymer composite (CPC) is effective to achieve high electromagnetic interference shielding effectiveness (EMI SE) at low filler loading. Nevertheless, the present segregated CPCs were only fabricated via the compression molding technique, which limits their practical ap…
Despite the fact that metastable $\ensuremath{\alpha}$-Ga${}_{2}$O${}_{3}$ becomes increasingly interesting for applications in $e.g.$ high-power electronics, its basic material properties remain unclear. The authors employ plasma-assisted molecular-beam epitaxy to grow $r$-plane-oriented thin films of this birefringe…
