We propose an approach to detect spin currents in an even zigzag graphene nanoribbon (ZR) junction, based on the peculiar intervalley selection rule in the ribbon when only zero-energy modes are involved in transport. Spatial spin separation arises from the bipolar property of the undoped ZR and opposite pseudoparitie…
Dendrimers are a new kind of polymers. They have gained widespread attentions due to their remarkable properties in recent years. In the present work, a facile and efficient synthetic approach to prepare poly(ester amine) dendrimers is presented. Three different generations of poly(ester amine) dendrimers are synthesi…
Abstract Biopolymers and natural fibers are receiving wide attention for the potential to have good performance composites with low environmental impact. A current limitation of most biopolymers is however their change in mechanical properties at elevated temperatures. This study investigates the mechanical properties…
Two bisbenzoxazine monomers containing carboxylic groups (named as BBA for based on bisphenol-A and BPA for based on phenolphthalein) were synthesized and their structure and properties were compared with each other. The chemical structures of these bisbenzoxazine monomers containing carboxylic groups were confirmed b…
In this paper, the bonding properties of polyvinylchloride (PVC)-based wood–plastic composite (WPC) materials bonded with acrylic adhesive have been studied. The results showed that dry compression shear strength of bonded specimens glued with acrylic adhesive was 6.12 MPa, and reached 58.8% of the strength of the PVC…
Abstract The addition of autonomic healing (frequently defined as self‐healing) capabilities to a water‐soluble polymer (polyethylene oxide, PEO) is for the first time reported. The self‐healing system consists of urea‐formaldehyde microcapsules filled with dicyclopentadiene and first‐generation Grubbs catalyst, dispe…
Prevention of coagulation appears not to be possible when a foreign surface is in contact with blood; the alternative concept of a clot lysing surface has therefore been suggested. In this work, a mimic of the fibrinolytic system was constructed on L605 cobalt-chromium coronary stents. Lysine which, immobilized on a s…
Measurements of platelet adhesion and fibrinogen adsorption from flowing whole blood to a series of polyethylene oxide (PEO)-based materials were carried out. A unique experimental design was used in which both quantities were measured in the same experiment. The materials consisted of a polyurethane (PU) as a matrix…
Polymer film deposition on agar in ambient air was achieved using the helium dielectric barrier discharge jet (DBD jet) fed with polymer precursors, and the bacterial growth inhibition due to the deposited film was observed. The DBD jet with precursor addition was more efficient at sterilization than a helium-only DBD…
We report a simple and highly efficient method for creating graphene nanostructures with gaps that can be controlled on the sub-10 nm length scale by utilizing etch masks comprised of electrochemically synthesized multisegmented metal nanowires. This method involves depositing striped nanowires with Au and Ni segments…
Interest in environmental-pollutant-induced oxidative stress and knowledge of the interactions between reactive oxygen species and cellular systems have increased in toxicology and microbial ecology considerably in recent decades. These reactive oxidants are produced by a variety of environmental sources: ionizing rad…
Adipose tissue engineering aims to grow fat tissue for soft tissue reconstruction after tumour resection or trauma. However, insufficient progenitor cell differentiation and poor vascularization compromise the generation of clinically applicable adipose tissue. The desired process of neo-adipogenesis seems to be diffi…
In this paper we report the synthesis of WO$_{3}$ thin films and investigate the effect of the structure on their optical properties. The WO$_{3}$ thin films are coated on glass substrates from both W and WO$_{3}$ targets by the magnetron sputtering method in (Ar+O$_{2}$) plasma under different deposition temperatures…
An analysis of the molecular structure of the copper(II) complexes with open-chain and macrocyclic malonamide-derived tetradentate ligands based on single crystal X-ray diffraction study of four copper(II) complexes [CuL 1 (H 2 O)]·4H 2 O, [CuL 2 (H 2 O)], [CuL 3 (H 2 O)], and [CuL 4 (H 2 O)] (H 2 L 1 = 1,4,8,11-tetra…
Metallhaltige Röhren: Die Strukturen mehrerer Eisen-haltiger C-Methylpyrogallol[4]aren(PgC1)-Nanoaggregate wurden in fester Phase und in Lösung untersucht. Die Aggregate haben eine röhrenförmige Architektur mit Eisen als Gerüstbestandteil (siehe Bild; grau C, rot O, türkis/blau Fe), und magnetische Analysen weisen auf…
Cell wall deterioration throughout enzymatic hydrolysis of cellulosic biomass is greatly affected by the chemical composition and the ultrastructure of the fiber cell wall. The resulting pattern of cell wall deterioration will reveal information on cellulose activity throughout enzymatic hydrolysis. This study investi…

We introduce a novel structure of inhomogeneous parallel plate waveguide suitable for advanced applications requiring frequency tunability. The structure relies on microstrip technology and consists of a periodic metallic lattice embedded in dielectric materials. The basic metal pattern is connected to the upper layer…
Yersinia pestis protein Pla is a plasmid-coded outer membrane protein with aspartic-protease activity. Pla exhibits a plasminogen (Plg) activator activity (PAA) that promotes the cleavage of Plg to the active serine-protease form called plasmin. Exactly how Pla activates Plg into plasmin remains unclear. To investigat…
Cisplatin (cis-diamminedichloroplatinum, CDDP) is one of the most potent anticancer drugs. However, the therapeutic value of CDDP is greatly compromised by its dose-limiting nephrotoxicity. This study was performed to investigate whether reduced glutathione (GSH) was able to reduce the kidney injury induced by CDDP an…
