A series of π-conjugated oligomer-acceptor dyads were synthesized that feature oligo(phenylene ethynylene) (OPE) conjugated backbones end-capped with a naphthalene diimide (NDI) acceptor. The OPE segments vary in length from 4 to 8 phenylene ethynene units (PE n -NDI, where n = 4, 6 and 8). Fluorescence and transient…
Biocarbon supported Ni catalysts have been prepared by facile impregnation of Ni species by microwave-heating and used for selective hydrogenation of nitrobenzene to cyclohexylamine. These catalysts were characterized by X-ray diffraction, Raman spectra, N2 sorption measurement, X-ray photoelectron spectroscopy, tempe…
Abstract There is a growing literature database that demonstrates the therapeutic potential of cold atmospheric plasma (herein referred to as plasma). Given the breadth of proposed applications (e.g. from teeth whitening to cancer therapy) and vast gamut of plasma devices being researched, it is timely to consider pla…
Slow vascularization often impedes the viability and function of engineered bone replacements. Prevascularization is a promising way to solve this problem. In this study, a new process was developed by integrating microcarrier culture and coculture to fabricate pre-vascularized bone microtissues with mesenchymal stem…
Herein we showcase the potential of ultrasound-responsive nanobubbles in enhancing macromolecular permeation through layers of the retina, ultimately leading to significant and direct intracellular delivery; this being effectively demonstrated across three relevant and distinct retinal cell lines. Stably engineered na…
Solid self-nanoemulsifying (S-SNEDDS) asymmetrically coated osmotic tablets of the poorly water-soluble drug Vinpocetine (VNP) were designed. The aim was to control the release of VNP by the osmotic technology taking advantage of the solubility and bioavailability-enhancing capacity of S-SNEDDS. Liquid SNEDDS loaded w…
The N-polyamide 6 (N-PA6) was used as a toughening agent to improve the mechanical properties of a thermosetting phenol formaldehyde (PF) resin. Then, molybdenum disulfide (MoS 2 ) and graphite (Gr) were added as friction modifiers to improve the tribological properties of PF resin–N-PA6 composite. In this article, it…
Cotton fiber and cottonseed are the two major products of cotton crop. The ratio of fiber and cotton is 100/150. Cotton fiber represents 85-90% of cotton’s total economic value. Thus, enhanced utilization of cottonseed products as industrial raw materials would greatly benefit cotton growers and processors. Defatted c…
The objective of this paper is to determine the high-current vacuum arc mode transition diagram of a horseshoe-type axial magnetic field (AMF) contact with long contact gap. Drawn arc experiments were carried out in an L-C discharging circuit. Horseshoe-type contacts with contact material of CuCr50 and contact diamete…
Micellization in water and reduction of the surface tension at water interfaces with air and oil are two archetypical properties of surfactants, caused by self-aggregation and Gibbs monolayer formation at the interfaces, respectively. We present here a new type of amphiphiles that possess a conical shape consisting of…
Intermolecular interactions in conjugated polymers influence crystallinity, self-assembly, and packing motif, factors which in turn crucially impact charge transport properties such as carrier mobility in organic electronic devices. Correlated alignment of molecular and crystalline morphologies provides direct pathway…
Phosphomolybdic acid supported on silica (PMoA), and phosphomolybdic acid supported on silica substituted with nickel (Ni-PMoA), cobalt (Co-PMoA), are prepared with different loadings. All catalysts have been characterized using thermogravimetric analysis (TGA), BET surface area, Solid-state 31 P NMR spectra, FT-IR, D…
Cardiomyopathy induced by doxorubicin (DOX) was recognized at an early stage and also several years after drug administration. Mesenchymal stem cells (MSCs) have many properties that make them suitable for preventive and/or regenerative therapies. In this study, we evaluated the effect of MSCs in the functional and th…
We demonstrate good agreement between the theoretical and experimental collision frequency of individual Pt nanoparticles (NPs) undergoing collisions at a Au ultramicroelectrode (UME) (5 μm radius) using electrocatalytic amplification provided by 15 mM hydrazine in 5 mM phosphate buffer (PB; pH 7) over 100 to 300 s. D…
A surface-confined aqueous reversible addition–fragmentation chain transfer (SCARAFT) polymerization method was developed to coat capillaries for use in capillary zone electrophoresis (CZE). SCARAFT polymerization primarily takes place on the inner surface of the capillary instead of in solution, which greatly improve…
In this study, we investigated the use of three-dimensional electrospun poly(lactic-co-glycolic acid)/poly(ε-caprolactone) (PLGA/PCL) scaffolds seeded and cultured with postnatal dental cells, for improved dental tissue regeneration. Wet-electrospinning combined with ultrasonic treatment was studied as a method to enh…
We investigate the effect of a skewed permanent magnet (PM) with overhang on the axial unbalanced magnetic force (UMF) of a PM motor, especially in the presence of static and dynamic eccentricities of a rotor. We derive the mathematical equations of the axial UMF acting on PM motor due to the skewed PM with overhang a…
In this work, we use flow visualization and rheometry techniques to study the dynamics and evolution of secondary flows in a model wormlike micellar solution sheared between concentric cylinders, i.e., in a Taylor-Couette cell. The wormlike micellar solution studied in this work contains cetyltrimethylammonium bromide…
A hierarchically porous partially graphitic carbon (HPGC) membrane with three-dimensionally networked nanotunnels is prepared and applied as a monolithic matrix for electrochemical (bio)sensing. The walls of the nanotunnels (∼40–80 nm in diameter) are composed of partially graphitic carbon with ordered mesopores (∼6.5…
Linalool has been extensively applied in various fields, such as flavoring agent, perfumes, cosmetics and medical science. However, linalool is unstable, volatile and readily oxidizable. A sensitive substance can be encapsulated in a capsule, so encapsulation technology can solve these problems. In this paper, linaloo…
