Assessment of nano-tribological properties (friction and wear) on polymer surface helps to understand their scratch, mar and wear properties. More polymers are used now for automotive, electronics, appliances, and building and constructions industries due to aesthetics and design freedom. Owing to their lower mechanic…
Low-temperature processable hybrid organic/inorganic based electronic devices, such as field-effect transistors (FETs), micro/nano energy generators, photodetectors, etc. offer practical solutions towards realizing low-cost, flexible self-powered autonomous systems. This work presents the method for `direct' integrati…
Like rigid objects, also soft and elastic manufactured materials for industrial and biomedical applications are subjected to fatigue stress that might speed up the aging process and even cause premature failures. The occurrence of early signs of damaging, like the arising of surface cracks, could avoid more severe cri…
Recently, interconnect based stretchable electronic devices have attained growing interest due to its application for various state-of-the-art technologies. Here, we report an engineered design of spiral interconnects for a series of stretchable networks referred to as the symmetrical series; wherein spirals connect t…
Textile based wearable, biocompatible and low-cost energy storage devices are highly in demand to overcome the issue of powering wearable sensors and electronic devices. In this work, we designed an environmentally friendly textile supercapacitor (SC) which operates with sweat equivalent electrolyte. For investigating…
Nuclear magnetic resonance, vibrational, structural and electronic properties for 4-isopropyl-N, N-Bis (4-azidophenyl) aniline (IPAPA) were determined by quantum chemical calculations of the DFT method. The results were compared with experimental 1H-NMR spectral data. Theoretical chemical calculations and experimental…
This paper presents a 2D analytical model for predicting the magnetic flux density distribution in slotless permanent-magnet (PM) linear tubular (PMLT) motors due to armature reaction effects based on the sub-domain method. According to this method, the machine cross-section is divided into the six sub-regions and Max…
This paper presents a miniaturized potentiostat readout circuit patch developed for electrochemical or biosensors. The presented patch has been fabricated on a flexible polyimide substrate using off-the-shelf electronics. In contrast to the traditional bulky equipment for electrochemical analysis, the presented patch…
The process called “polydopamine-dip coating” was successfully applied to modify the surface of poly(2-hydroxyethyl methacrylate), PHEMA, cryogel disks for the first time. This facile surface modification process fitted very well to the chemistry of cryogels since the integrity of the cryogel disks was maintained duri…
Beech wood is mainly used for furniture, plywood, decorative veneer manufacturing or packaging. Timber or lumber is traditionally dried in kilns by processes often taking several weeks. This research deals with more rapid process called contact-drying process. Drying was performed using the heating plates with a tempe…
This work reports the fabric-based supercapacitors (FSCs) using silver coated textile as the current collector. The electrochemical properties of the device in PVA-KCl gel electrolyte was studied. The performance of the device was further improved by printing an inhouse formulated graphite paste as the active electrod…
We present a method for printing conductive polymers onto P(VDF-TrFE) nanofibers to create all-polymer piezoelectric devices. Inkjet printing is an attractive fabrication approach for rapid prototyping of flexible electronics, but until now with limited applications in developing P(VDF-TrFE) nanofiber-based devices. W…
Abstract A three‐dimensional fine‐woven punctured felt green body was used as a preform to generate an advanced ceramic. After chemical vapor infiltration and several cycles of precursor infiltration and pyrolysis, the pyrolysis carbon, as well as the silicon carbide and zirconium carbide ceramic matrix were formed. T…
Green corrosion inhibitors are biodegradable. Some research groups have reported the successful use of natural substances to inhibit the corrosion of metals in acidic and alkaline environments. Among the various green inhibitors, plant extracts are becoming increasingly popular. In this study, the inhibition and adsor…
Abstract 3D and robust Poly(l‐lactide) (PLLA) fibrous materials has been fabricated via electrospinning and evaporation welding for high‐efficiency dye adsorption and oil/water separation simultaneously. Herein, sodium dodecyl benzene sulfonate (SDBS) in spinning solution has been found to stimulate fibrous materials…
Abstract A detailed investigation into the role of initiator structure, the presence of an initiator, and basicity of the non‐nucleophilic base in the chain‐growth condensation (CGC) synthesis of poly(N‐octyl benzamide) was conducted. A series of phenyl ester dimethyl amide initiators with different leaving groups wer…
Abstract Coarse‐graining routines are necessary for simulating systems involving large molecules. However, their accuracy is limited by excessive simplifications that are made during the upscaling procedure. The time autocorrelation of the shape anisotropy of grains in cis‐polybutadiene chains is computed, and it is c…
By using a standard stretch spline as the research object, the influence of gas counter pressure (GCP) technology on melt foaming behavior in chemical foaming injection molding (CFIM) process was investigated. Related experimental line for GCP assisted CFIM foam was designed, and the effect of GCP technology on melt f…
Natural tanzanites usually show strongly trichroic coloration from violet to blue, and brown colors in different directions. However, this characteristic is easily changed to violet-blue dichroism after heat treatment. Moreover, the cause of color modification after heating is still controversial. A few researchers ha…
This paper tries to relate Pedersen’s model on partial discharges and work carried out by Bruning and co-workers on the possibility of the existence of charging phenomena below inception voltage, which may eventually cause deterioration of polymeric insulation. Moreover, with the aid of the Electromagnetic theory, som…
