The incorporation of nanoparticles into a polymer can lead to a considerable improvement of mechanical properties. Especially, the toughness and stiffness of the nanocomposite can be enhanced at the same time. Therefore, a homogeneous distribution of fillers within the matrix is required. In this research study, the f…
This study investigates the development of sago ( Metroxylon sagu ) starch‐based edible films for potential hard capsule application. In its conduct, films were made with different amount of starch (9, 10, and 11% w/v) and glycerol (25, 30, 35, and 40% w/w starch) by casting method. The films were characterized by phy…
It has been reported several times that some organic luminogens with aggregation-induced emission (AIE) characteristics exhibit the abnormal phenomenon of crystallization-induced blueshift fluorescence, which makes them suitable for utilization as luminescence color-switching materials. Because of the attractive appli…
Chetomin is a promising molecule with anti-tumor activities in the epipolythiodioxopiperazine family of fungal secondary metabolites; however, strong hydrophobicity has limited its further applications. In this work, chetomin was encapsulated into polymeric micelles to obtain an aqueous formulation, and the chetomin l…
ABSTRACT The alternating multilayered damping composites, which were consisted of chlorinated butyl rubber (CIIR) layers and poly(vinyl chloride) (PVC) layers, were first prepared through multilayered coextrusion technology. The multilayered structure was controlled by adjusting the layer number or the thickness ratio…
The slowest (p=1) mode relaxation of several polyisoprenes has been experimentally isolated by thermally stimulated depolarization current techniques. Close to the glass transition the p=1 mode deviates from the exponential behavior assumed by Rouse and tube-reptation theories. This effect is found to be a consequence…
The scaled versions of the newly introduced [S. S. Xantheas and J. C. Werhahn, J. Chem. Phys. 141, 064117 (2014)] generalized forms of some popular potential energy functions (PEFs) describing intermolecular interactions--Mie, Lennard-Jones, Morse, and Buckingham exponential-6--have been used to fit the ab initio rela…
Novel photosensitive azobenzene-containing substances with sorbitol- and lactate-based chiral fragments were synthesized to serve as chiral-photochromic dopants in cholesteric mixtures. Owing to the presence of chlorine or methyl lateral substituents in the azobenzene fragment of the dopants, the photoinduced Z-form o…
Reactive air brazing (RAB) is a promising and economic method for joining ceramic to metal as well as ceramic to ceramic. Hybrid joints gain importance in the field of challenging applications such as gas separation or solid oxide fuel cells. While the ceramic partner is often directly chosen due to its functionality,…
The solubilities of lauric acid in methanol, ethanol, propanol, n -butanol, n -pentanol, n -hexanol, isobutanol, and isoamylol were measured by synthetic method in the temperature ranging from (276.17 to 306.12) K. Results of these measurements were correlated by the modified Apelblat equation, the λ h equation and ac…
Nanomaterials are employed in extensive variety of commercial products such as electronic components, cosmetics, food, sports equipment, biomedical applications, and medicine. With the increasing utilization of engineered nanomaterials, the potential exposure of human to nanoparticles is rapidly increasing. Nowadays w…
In multiband superconductivity, the case where the single electron hopping between different Fermi surface spots of different symmetry is forbidden by selection rules is recently attracting a large interest. The focus is addressed to superconductivity made of multiple condensates with different symmetry where the chem…
Doping with noble metal nanoparticles (NPs) is an effective method to tune the photoluminescence (PL) properties of semiconductor materials. The mechanism is widely attributed to the localized surface-plasmon-resonance (SPR) effect of the metal NPs, while the contribution of potential barrier at the interface between…
Explicit formulas are derived analytically for the first derivatives of a (i) polarizable, (ii) high-rank multipolar electrostatic potential energy function for (iii) flexible molecules. The potential energy function uses a machine learning method called Kriging to predict the local-frame multipole moments of atoms de…
Multifunctional material brings many interesting issues because of various potential device applications. Using first principles calculations, we predict that the graphitic carbon nitride (g-C4N3) nanotubes can display multifunctional properties for both spintronics and optical device applications. Very interestingly,…
This paper reviews electron emission from negative electron affinity (NEA) diamond and gives account of the recent developments in alternatives to hydrogen‐termination for producing NEA diamond surfaces, particularly using lithium on oxygen‐terminated diamond. We discuss the background and motivation for using alkali…
The effect of carbon nanotube aspect ratio (AR) on the percolation characteristics of their polymer composites was investigated by melt blending the multi-wall carbon nanotubes (MWCNTs) with different AR with a thermoplastic elastomer. Previously, most studies reported the effect of aspect ratio of MWCNTs only in the…
Pyridoxal hydrazonato molybdenum(VI) complexes were prepared by the reaction of the corresponding hydrazone (H2L1 = pyridoxal isonicotinic acid hydrazone, H2L2 = pyridoxal benzhydrazone, H2L3 = pyridoxal 4-hydroxy benzhydrazone) and [MoO2(acac)2] under appropriate conditions. The complexes can be classified into three…
Manganese oxide/carbon nanofiber (MnOx/CNF) composites were successfully fabricated as freestanding electrodes through incorporating different manganese sources of nanostructured MnO2 or Mn(CH3COO)2·4H2O into polyacrylonitrile (PAN) solution by electrospinning and a subsequent carbonization method. The MnO2 with a rod…
Microcrystalline cellulose (MCC) was functionalized with quaternary amine groups for use as an adsorbent to remove Congo Red dye (CR) from aqueous solution. The ultrasonic pretreatment of MCC was investigated during its functionalization. Characterization was conducted using infrared spectroscopy (FT-IR), X-ray photoe…
