The Monte Carlo programme PENEPMA performs simulations of X-ray emission from samples bombarded with electron beams. It is both based on the general-purpose Monte Carlo simulation package PENELOPE, an elaborate system for the simulation of coupled electron-photon transport in arbitrary materials, and on the geometry s…
Although cytotoxic chemotherapy is widely used against epithelial ovarian cancer (EOC), adverse side effects and emergence of resistance can limit its utility. Therefore, new drugs with systemic delivery platforms are urgently needed for this disease. In this study, we developed linalool-incorporated nanoparticles (LI…
This paper presents the design and testing of an electrically controllable magnetostrictive spring that has a dynamically tunable stiffness (i.e., a magnetostrictive Varispring). The device enables in situ stiffness tuning or stiffness switching for vibration control applications. Using a nonlinear electromechanical t…
Highly conductive indium zinc oxide (IZO) thin films were successfully fabricated via a self-combustion reaction for application in solution-processed thermoelectric devices. Self-combustion efficiently facilitates the conversion of soluble precursors into metal oxides by lowering the required annealing temperature of…
Abstract Inspired by the design of composite materials, we propose a new composite supercapacitor that comprises an integrated cell with high‐power‐ and high‐energy‐related electrode materials. The composite electrochemical double‐layer capacitor (EDLC) is the equivalent circuit of a high‐power EDLC of power P1 and en…
Surface-active polymers that display nonfouling properties and carry binding groups that can adsorb onto different substrates are highly desirable. We present a postmodification protocol of an active-ester-containing polymer that allows the creation of such a versatile platform. Poly(pentafluorophenyl acrylate) has be…
ABSTRACT High performance epoxy resins have attracted much research interest in the last decades. Herein, two novel epoxy monomers containing cycloaliphatic hydrocarbon, 1,4‐bis(4‐(N,N‐diglycidylamino)phenoxy)cyclohexane (CyhEP) and 1,3‐bis(4‐(N,N‐diglycidylamino)phenoxy)adamantane (AdaEP) were synthesized and charact…
In this study, silk fibroin was extracted from cocoons of silkworms and fabricated into nonwoven mats by electrospinning method. A new model based on the group method of data handling (GMDH) and artificial neural network (ANN) was developed for estimation of the average diameter of electrospun silk fibroin nanofibers.…
In this study, the Al 3+ –Sn 4+ substitution reaction in the AlN-doped SnO 2 thin films is confirmed by photoluminescence and X-ray photoelectron spectrum analysis. Also, both Al 3+ –Sn 4+ and N 3– –O 2– substitution reactions are verified by computational simulation, Vienna ab initio simulation package (VASP). The co…
BACKGROUND: Single photon emission computed tomography (SPECT) is an indispensable tool in the determination of the in vivo fate of polymeric micelles. However, for this purpose, the micelles need to be radiolabeled, and almost all radiolabeling procedures published to date involve the conjugation of a chelating agent…
A series of over 30 differential equations were solved to model experimental data on urethane foam formation. Methyl formate and C5–C6 hydrocarbons were used as physical blowing agents, and water was used as a chemical blowing agent. The rate of evaporation of the physical blowing agents was estimated using an overall…
Low voltage imaging, X-ray microanalysis and X-ray mapping has become very important for the investigation of nanomaterials and their surfaces. This is especially true for low voltage imaging of non-conductive samples and beam sensitive samples. Operating the SEM at lower accelerating voltage allows for greater surfac…
We have demonstrated that mussel-inspired polydopamine can serve as an intermediate coating layer for covalently attaching oligonucleotides on nanostructures of diverse chemical nature, which are made possible by the universal adhesion and spontaneous reactivity of polydopamine. Our results have shown that polydopamin…
A simple, facile and low-cost method for recycling of supercapacitor materials is proposed. This process aims to recover some fundamental components of a used supercapacitor, namely the electrolyte salt tetraethyl ammonium tetrafluoroborate (TEABF4) dissolved in an aprotic organic solvent such as acetonitrile (ACN), t…
Although DBP (di-n-butyl phthalate) is commonly encountered as an artificially-synthesized plasticizer with potential to impair fertility, we confirm that it can also be biosynthesized as microbial secondary metabolites from naturally occurring filamentous fungi strains cultured either in an artificial medium or natur…
Cost effective and fast ultra-high-temperature testing methods such as oxyacetylene torch testing are extremely useful for the rapid screening of ultra-high-temperature ceramic (UHTC) materials for hypersonic applications. There is no report in the literature, however, of an organised study to measure the heat flux an…
In this paper, we present a first-principles and molecular dynamics study to delineate the functionalization-induced changes in the local structure and the physical properties of amorphous polyaniline. The results of radial distribution function (RDF) demonstrate that introducing -SO3(-)Na(+) groups at phenyl rings le…
The fluorescent dye DAPI is useful for its association with and consequent amplification of an ∼460 nm emission maximum upon binding to dsDNA. Labelling with higher DAPI concentrations is a technique used to reveal Pi polymers [polyphosphate (polyP)], with a red-shift to ∼520-550 nm fluorescence emission. DAPI-polyP e…
We report herein the synthesis of a novel nest structured electromagnetic composite through in-situ chemical polymerization of 3-methyl thiophene (3MT) in the presence of the BaFe11.92(LaNd)0.04O19-TiO2 (BFTO) nanoparticles and MCNTs. As an absorbing material, the BFTO/MCNTs/P3MT/wax composites were prepared at variou…
Foamed polylactide (PLA), PLA–PBAT (poly (butylene adipate‐co‐terphathalate)) blend and their composites with CaCO3 were prepared in a batch process using supercritical carbon dioxide (CO2) at 12 MPa and 45°C. The solubility of CO2 and its diffusion patterns in different PLA samples was investigated. PLA systems had a…
