A novel thiol functionalized bis-silane PMO precursor was synthesized by highly efficient thiol acid-ene chemistry between the double bonds of 1,2-(E)-bis(triethoxysilyl)ethene and thioacetic acid. After aminolysis the self-assembly process of the formed SH-precursor with Pluronic P123 under acidic conditions yields t…
Meso-scale simulations are performed to obtain a fully cross-linked, equilibrated structure of an epoxy network. We derive and study the interactions giving rise to the final structure. Both equilibrium structures with no cross-links and fully cross-linked are examined. The simulations were performed using a recent di…
The mechanical behavior of a three-dimensional cross-linked fiber network embedded in matrix is studied in this work. The network is composed from linear elastic fibers which store energy only in the axial deformation mode, while the matrix is also isotropic and linear elastic. Such systems are encountered in a broad…
We demonstrate the modification of the electronic properties of single layer chemical vapor deposition (CVD)-grown graphene by deep ultraviolet (DUV) light irradiation. The shift in the G and 2D bands in Raman spectra towards higher wavenumber suggests p-doping in graphene field effect transistors (FETs). In the trans…
Simple conjugation of tyrosine-phosphate with tetraphenylethylene generates a new amphiphile, which not only undergoes enzymatic dephosphorylation to generate a relative hydrophobic residue for alkaline phosphatase (ALP) detection with significant enhancement of the fluorescence signals, but also self-assembles in wat…
NaAlH4, a prototypical high energy density complex hydride, possesses a favorable thermodynamics and high hydrogen storage capacity. However, the poor kinetics and degradation of cycling stability retard its practical application. To ease these problems, CeB6, CeF3 and CeO2 nanoparticles with a size of about 10 nm are…
Presented in this paper is an “armed” high-genus block copolymer vesicle (g = 18) which has excellent blood compatibility and more internal barriers than simple polymer vesicles (g = 0) for controlled anti-cancer drug delivery. The high-genus vesicle also shows better antibacterial activity against both Gram-positive…
A novel type of nanoporous carbon with a 3D nanonetwork-interconnected 2D ordered mesoporous structure is successfully fabricated based on the self-assembly of triblock copolymer F127 and phenol–formaldehyde resol among the nanonetwork from tetraethyl orthosilicate. The as-constructed nanoporous carbons have two uniqu…
This paper summarizes the results of our recent studies on the development of an artificial molecular rotor system that exhibits a change in redox potential and photoluminescence in response to external stimuli such as heat and photons. The molecular rotor is made of copper complexes bearing two bidentate ligands; the…
H2 generation from the reaction between Mg nanoparticles and water can be significantly promoted by low cost chlorides. The promotion effect exhibits strong correlation with the OH(-) affinity of the corresponding cation. This interesting observation offers a simple and effective solution to portable H2 generation und…
New biocomposites consisting of poly (butylene succinate) (PBS) and various content (0–70 wt%) of oil palm mesocarp fiber (OPMF) or oil palm empty fruit bunch fiber (OPEFBF) were fabricated by melt blending and subsequently hotpress moulding. The tensile, flexural, and impact properties of those biocomposites were eva…
The TiO2-polyaniline (PANI) core-shell nanofibers with unique ultraviolet (UV) photoresponse were designed and fabricated. When the core-shell nanofibers were tested in an oxygen (O2) and a non-oxygen environment under UV illumination, respectively, a decrease and an increase in photoconduction were observed, which su…
Electrospinning of gamma cyclodextrin (γ-CD) nanofibers from a DMSO–water solvent system was achieved without using a carrier polymeric matrix. The effects of viscosity and rheological properties on the electrospinnability of γ-CD solutions were examined. XRD and HR-TEM studies confirmed that the electrospun γ-CD nano…
Over the past several decades, numerous studies have attempted to define the general role that proteins play in the nucleation of biominerals in organisms. Recently, with the emergence of the non-classical nucleation scheme involving pre-nucleation cluster formation, amorphous mineral cluster assembly, and maturation/…
A seminal paper [D. R. Nelson, Nano Lett., 2002, 2, 1125.] has proposed that a nematic coating could be used to create a valency for spherical colloidal particles through the functionalization of nematic topological defects. Experimental realizations however question the complex behaviour of solid particles and defect…
In this article, we established a fluorescent chiral recognition and detection method for cysteine based on the L-glutathione (L-GSH)-stabilized Ag nanoclusters (AgNCs) with high selectivity and sensitivity. A fast and green microwave (MW)-assisted strategy has been employed for synthesizing water-soluble fluorescent…
A solid-state photocapacitor is prepared, utilizing iron pyrite (FeS2) as both the photoactive material and blocking electrode, which exhibits a high performance near-infrared (NIR) photodetectivity of 1.6 × 10(11) Jones, an energy density of 1.13 × 10(4) J g(-1) and a specific capacitance of 37.5 mA h g(-1) directly…
Research into polymer nanofibers has increased significantly over the last decade, prompting the need for a comprehensive monograph examining the subject as knowledge of their properties and potential applications has increased.Postgraduate students and researchers new to the field will benefit from the "from material…
In this paper, we analyze the theoretical limits of a metamaterial-based converter with orthogonal linear eigenpolarizations that allow linear-to-elliptical polarization transformation with any desired ellipticity and ellipse orientation. We employ the transmission line approach providing a needed level of the design…
