A step-shear deformation imparts an instantaneous, anisotropic stimulus onto a microphase-separated block copolymer mesophase. In response to the concomitant molecular stretching and collective deformation of the morphology, the system relaxes toward a long-lived, pseudometastable state with a minuscule residual shear…
Abstract Capsaicin (CAP) ist seit Längerem für dessen analgetische Wirkung sowie seit Kurzem für seine Antitumoraktivität an verschiedenen Zelltypen bekannt. Aufgrund seiner Schärfe und der benötigten hohen Dosen zur Erzielung einer signifikanten Aktivität hat dieser Wirkstoff bis heute keine Anwendung in der Krebsthe…
Abstract The microstructure of aragonite, one of the main bio-mineral and component of bio-inspired materials, was described in numerous investigations. Using transmission electron microscopy (TEM), for the first time we show the effect of temperature on aragonite microstructure. The local increase of (0.5 0.5 0) refl…
Abstract The glass‐forming region of the BaO‐La 2 O 3 ‐B 2 O 3 ternary system was determined by using a containerless processing. Moreover, we prepared x BaF 2 ‐(35‐ x )BaO‐15La 2 O 3 ‐50B 2 O 3 ( x = 0‐35 mol%), x BaF 2 ‐(20‐ x )BaO‐20La 2 O 3 ‐60B 2 O 3 ( x = 0‐20 mol%), x BaF 2 ‐(20‐ x )BaO‐15La 2 O 3 ‐65B 2 O 3 (…
ABSTRACT A series of novel aqueously soluble semi‐aromatic (co)polyamides, poly[(ethylenedioxy)bis(ethylene) terephthalamide]‐ ran ‐poly[(ethylenedioxy)bis(ethylene) (2,5‐dihydroxy‐3,6‐diallyl)terephthalamide] (CRPAOT‐x), were prepared via the solid‐state Claisen rearrangement reaction of poly[(ethylenedioxy)bis(ethyl…
New silver nanocomposites (AgNCs) based on copolymers of N ‐vinylpyrrolidone with N,N‐diallyl‐N′‐acetylhydrazine, poly (VP‐DAAH), and 3‐methacryloxytetrahydrothiophenedioxide‐1,1, poly (VP‐MTT), have been developed. The reduction of silver ions into silver nanoparticles was achieved using NaBH 4 as reducing agent. UV‐…
Flexoelectricity describes the coupling between polarization and strain gradients and presents a strong size dependence at nanoscale. In the current work, based on the extended linear piezoelectricity theory with flexoelectricity, we study bending of piezoelectric beams with consideration of flexoelectric effect. When…
In our previous studies, CuCl 2 showed excellent removal efficiency for trace phosphine in circular hydrogen of a polysilicon chemical vapor decomposition (CVD) stove. In this study, the investigation of properties and performances of CuCl 2 supported on γ-Al 2 O 3 with high surface area were conducted. Various charac…
Abstract The solubility of 2-chloro-3-(trifluoromethyl)pyridine (CTP) in ethyl acetate, n-butyl alcohol, 2‑propanol, methanol, trichloromethane, acetonitrile, and acetone under atmospheric pressure was measured at 273.15–303.15 K. The solubility of CTP in all eight solvents increased with the increase in temperature.…
Abstract One‐pot synthesis of polymeric nanostructures, by using ultrasound without adding initiators and surfactants, is a straightforward approach that has attracted significant attention in polymer science. In this study, the ultrasonic polymerization technique is employed to synthesize poly(ethylene glycol) based…
The structure regulation of cuprous oxide (Cu 2 O) has been realized from submicrometric cubes to irregular hollow polyhedrons and hollow truncated octahedrons. It is suggested that the evolution of Cu 2 O exotic morphology and hollow structure are caused by an inside–out Ostwald ripening mechanism in the synthetic sy…
In this work, we demonstrate a simple approach for growing 1D (one-dimensional) inorganic chains of K(C 6 H 16 N) 3 Mo 8 O 26 ·H 2 O polyoxometalates (POMs) from its colloidal soft-oxometalate (SOM) phase through the variation of pH. The structure is composed mainly of a 1D inorganic chain with a β-Mo 8 O 26 4− bindin…
The detailed analysis of resistivity $(\ensuremath{\rho})$ for single-crystalline ${\mathrm{EuTi}}_{1\ensuremath{-}x}{\mathrm{Nb}}_{x}{\mathrm{O}}_{3}\phantom{\rule{4pt}{0ex}}(x=0.10$--0.20), an itinerant ferromagnet with very low Curie temperature $({T}_{C})$, reveals that the charge conduction in this system is extr…
Melts of three-armed star polymers have been simulated using a coarse-grained model parameterized by atomistic simulations of polyethylene. The bonds between the highly coarse-grained, and hence soft, polymer beads are explicitly prevented from crossing by the TWENTANGLEMENT algorithm. The three melts of symmetric sta…
Abstract The analysis of three-dimensional neutron spin polarization vectors, using a technique referred to as spherical neutron polarimetry (SNP), is a very powerful means of determining complex magnetic structures in magnetic materials. However, the requirement to maintain neutrons in a highly polarized state has ma…
In the past, significant effort has been made to develop ultrathin membranes exhibiting physiologically relevant mechanical properties, such as thickness and elasticity of native basement membranes. However, most of these fabricated membranes have a relatively high elastic modulus, ∼MPa–GPa, relevant only to retinal a…
ABSTRACT This work describes the enhanced mechanical properties of composite polydimethylsiloxane/poly(methyl methacrylate) (PDMS/PMMA)/multi‐walled carbon nanotubes (MWCNTs) nanofiber membrane and its application in the phenol separation from saline wastewater. MWNCTs with varied content were immobilized in the membr…
heterostructures involving tailored photoelectric properties.
One intriguing metamaterial absorber with anapole excitation in the microwave frequency range is proposed for the first time. The presented subwavelength structure is composed of three copper strips to effectively improve the absorptivity. Owing to the constructive interference between toroidal and electric dipoles, a…
Abstract Derzeit publizieren Chemiker aller Fachrichtungen ca. 50 000 Kristallstrukturen pro Jahr, von denen es sich bei der überwältigenden Mehrheit um Röntgenstrukturen handelt. Wir setzen Elektronen‐ statt Röntgenbeugung ein, um die Struktur zweier molekularer Verbindungen zu bestimmen. Zu diesem Zweck wurde ein EI…
