For many years, chemical pesticides have been performed to control different pests and diseases and this may be due to their broad spectrum of action, easy of application and the relatively low cost. But these chemicals have environmental risks, thus alternative control agents are needed. Chitosan is one of the novel…
The ability to track interfacial dynamics of a single nanoparticle at the solution-solid interface is crucial for understanding physical, chemical, and biological processes, but it remains a challenge. Here, we demonstrated a plasmonic imaging technique that can track unlabeled nanoparticles at the solution-solid inte…
It is well known that dielectric breakdown in a liquid generates cavitation bubbles and shock waves. Here we demonstrate that when the liquid is bounded by two solid glass boundaries (10--20-$\ensuremath{\mu}\mathrm{m}$ separation), rings of microscopic bubbles can be nucleated around the laser-induced cavitation bubb…
Abstract This paper investigates nematic liquid crystals in three-dimensional curved space, and determines which director deformation modes are compatible with each possible type of non-Euclidean geometry. Previous work by Sethna et al showed that double twist is frustrated in flat space R 3 , but can fit perfectly in…
In our work, zinc hexahydrophthalate (HHPA-Zn) was synthesized and its β-nucleating activity in isotactic polypropylene (iPP) was confirmed. The single crystals of HHPA-Zn were obtained for the first time, with the crystal structure analyzed. The results of differential scanning calorimeter (DSC) and wide-angle X-ray…
One of the challenges of the century is to reach compatibility between the required resistance and the usage of lightweight building materials that may negatively affect the mechanical properties. Natural fibers nowadays are used as enhancers in the industrial field. Hence, the fibers contribute by giving an ideal sol…
Understanding factors that underpin the signs and magnitudes of electron spin–spin couplings in biradicaloids, especially those that are integrated into highly delocalized electronic structures, promises to inform the design of molecular spintronic systems. Using steady-state and variable temperature electron paramagn…
The properties of native spider silk vary within and across species due to the presence of different genes containing conserved repetitive core domains encoding a variety of silk proteins. Previous studies seeking to understand the function and material properties of these domains focused primarily on the analysis of…
Gold nanoparticles (AuNPs) are the most thoroughly studied nanoparticles because of their remarkable optical properties. Color changes in assays that use AuNPs can be easily observed with the naked eye, resulting in sensitive colorimetric methods, useful for detecting a variety of biological molecules. However, while…
Protein purification is of vital importance in the food industry, drug discovery, and other related fields. Among many separation methods, polyelectrolyte (PE)-based phase separation was developed and recognized as a low-cost purification technique. In this work, spherical polyelectrolyte brushes (SPBs) with a high sp…
Abstract Polycrystalline Nd 2 CoIrO 6 double perovskite crystallizes in monoclinic crystal structure with P 2 1 / n space group. The average grain size of powder sample is 400–500 nm. The dielectric, impedance and ac conductivity of the sample were studied in the temperature range 5–300 K and in the frequency range 20…
Uranium is one of the strategic minerals used mainly in energetics. The main purpose of uranium mining is to achieve maximum production to meet the rapidly growing demand for energies. It needs to become aware that technological progress in mining processes could significantly reduce the negative impacts associated wi…
Traditional liquid marbles (LMs), liquid droplets encapsulated by hydrophobic particles at the liquid-gas interface, are restricted by their short lifetime and low heat transfer efficiency. Herein, a new paradigm for LMs immersed in various liquid mediums with massive enhanced heat transfer and spatial recognition is…
Regenerated cellulose fibers were prepared by dry-jet wet spinning of cellulose solutions using three different solvents: the ionic liquids 1-butyl-3-methylimidazolium chloride (BMIMCl) and 1-ethyl-3- methylimidazolium diethyl phosphate (EMIMDEP), and the solvent used in the lyocell process, N-methylmorpholine N-oxide…
INTRODUCTION: Glioblastoma multiforme is the most common and the most aggressive primary brain tumor, with a median survival of 14 months. This dismal prognostic has turned research toward nanomedicine as a new therapeutic approach that can deliver therapeutic compounds to GBM. AREAS COVERED: The review covers recent…
Abstract Poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) films are attracting famous applications in antistatic coating, energy storage and conversion, printed electronics, and biomedical fields due to their conductivity, optical transparency and flexibility. However, PEDOT:PSS has poor dispersion…
Abstract Graphene‐based composite is promising as thermal interface material (TIM) due to its outstanding thermal properties. However, there are some bottlenecks to excellent performance, such as agglomeration of particles and undesirable voids between nanoplatelets. In this work, a composite with three‐dimensional (3…
Fabrication of a 3D in vitro model that mimics the artery takes an important role in understanding pathological cell behaviors and mechanisms of vascular diseases by proposing an advanced model that can recapitulate a native vessel condition in a controlled manner. Because a model geometry and the structure of cells a…
Abstract Polymers are a class of materials that provide unparalleled benefits to humanity, fulfilling countless needs in an exceedingly broad range of applications. Because of their ubiquity and current ways of producing them, polymers also pose significant challenges to the environment. Inspired by a previous publica…
This work aims to achieve the excellent microwave absorption in layered dielectric nickelate compounds. The phase, microstructure, electromagnetic properties and microwave absorption of the Sr modified La2-xSrxNiO4±δ (x=0, 0.3, 0.5, 0.75) nickelates were investigated, determining the analysis of the role of Sr doping…
