Abstract Achieving topological transformation in an inorganic chemical system is an ongoing challenge. We show that such a topological transformation can be achieved in a simple metal‐oxide based inorganic system of soft‐oxometalates (SOMs). Starting from a dispersion of heptamolybdate‐based SOM nanotubes, molybdenum…
According to the dimensionless formulae of DOP (depth of penetration) of a rigid projectile into different targets, the resistive force which a target exerts on the projectile during the penetration of rigid projectile is theoretically analyzed. In particular, the threshold V c of impact velocity applicable for the as…
Dimensional stability of wood plastic composites (WPCs) made from polypropylene and pine wood flour with and without coupling agent was investigated. The pine wood flour was prepared from wood chips which had been immersed, respectively, in boiling water for 1 h, 3 h, and 5 h or in distilled water for 1 day, 3 days, a…
The study of cell immobilization on delicate polymer by an air atmospheric pressure plasma jet (AAPPJ) is required for its medical application. The aim of this study was to evaluate whether AAPPJ treatment induce cell immobilization effect on delicate polymers without significant change of surface roughness by AAPPJ t…
Flexoelectricity is known as the electromechanical coupling effect between the strain gradient and the polarization. In this study, a flexoelectric sensor is laminated on conical shells to monitor the natural modal signal distributions. The sensing mechanism of a generic flexoelectric sensor patch is presented first.…
We address electromagnetic (EM) wave scattering by an infinite coated cylinder at an arbitrary incidence angle. The time-averaged EM energy stored inside the core-shell cylinder is analytically calculated for TM- and TE-polarized incident plane waves. An analytical expression relating the internal energy to the absorp…
Cyclo[8]pyrrole (C8) is an octapyrrolic expanded porphyrin. In its diprotonated form it stabilizes strong supramolecular complexes (association constants of ca. 10 5 M –1 ) in benzonitrile with both the zinc porphyrin carboxylate (ZnP) and pyrene carboxylate (Py) anions via a combination of hydrogen-bonding and electr…
We theoretically demonstrate that nanocomposites made of colloidal semiconductor quantum dot monolayers placed between metal nanoparticle monolayers can function as multilayer hyperbolic metamaterials. Depending on the thickness of the spacer between the quantum dot and nanoparticle layers, the effective permittivity…
Biodegradable foams are a key area of growth for packaging applications. Starch-based materials have been a successful environmentally degradable polymer. However, making foams out of these materials has been challenging due to their chemical composition and consequent low miscibility in CO 2 . We examine the potentia…

In this research a type of wood plastic composites (TR‐WPCs) is prepared by blending tea residue (TR) with high‐density polyethylene (HDPE). The chemical composition of TR was analyzed quantitatively. The effects of TR content, compatibilizers, and nanofillers on the structure, morphology, and mechanical properties we…
Ethynyl-substituted siloxysilsesquioxanes are promising building blocks for a wide range of substances based on a POSS/DDSQ core, especially for (oligo-)polymer syntheses and modifications (the formation of hybrid materials with interesting photophysical and mechanical properties). In this study, we report on a series…
ABSTRACT Anisotropic cetylpyridinium modified magnetic montmorillonite/polyimide (CPC‐Fe 3 O 4 ‐MMT/PI) composite films were prepared based on CPC‐Fe 3 O 4 ‐MMT capable of exfoliation and magnetic‐field response via in situ polymerization and relatively low magnetic field adjustment (0.6 T) in the film casting followe…
The interaction of hydrogen atoms and molecules with a silica surface is relevant for many research and technological areas. Here, the dynamics of hydrogen atoms colliding with an H-preadsorbed β -cristobalite (0 0 1) surface has been studied using a semiclassical collisional method in conjunction with a recently deve…
Microwave (MW) H 2 plasmas with small admixtures of CH 4 and/or B 2 H 6 used for doped diamond deposition have been studied by infrared absorption and optical emission spectroscopy (OES) techniques. The experiments were carried out in order to analyze the dependence of the plasma chemistry on several parameters in the…
The crystallization of 16 human antibody Fab fragments constructed from all pairs of four different heavy chains and four different light chains was enabled by employing microseed matrix screening (MMS). In initial screening, diffraction-quality crystals were obtained for only three Fabs, while many Fabs produced hits…
Polyamide66 (PA66) and polyamide66/sepiolite (PA66/sepiolite) nanocomposites at 1, 3, 5, 7, and 9 wt% clay loading were prepared and injected to simulate industrial processing. Tensile tests were performed in the samples, and scanning electron microscopy was used to characterize the fracture surface. The samples were…
The authors show that nanocrystalline diamond (NCD) thin films prepared by microwave plasma enhanced chemical vapor deposition apparatus with a linear antenna delivery system are well compatible with epithelial cells (5637 human bladder carcinoma) and significantly improve the cell adhesion compared to reference glass…
Abstract. The varied aspect ratios observed in the Antarctic marine diatom Eucampia antarctica are described and quantified. Data are compiled from detailed measurements of the gross morphology of winter stage specimens found in samples of modern marine sediments. Surface sediment samples come from a range of oceanogr…
To characterize the nonlinear relationship between load and displacement and its dependency on temperature and time variations, the rate form of thermomechanical constitutive equations for shape memory polymers is newly derived. Experimental tests of the shape memory polymers are analyzed to acquire the parameters nee…
