The Staphylococcus aureus genome contains three toxin-antitoxin modules, including one mazEF module, SamazEF. Using an on-column separation protocol we are able to obtain large amounts of wild-type SaMazF toxin. The protein is well-folded and highly resistant against thermal unfolding but aggregates at elevated temper…
A numerical study on the dynamic response of a generic rigid water-landing object (WLO) during water impact is presented in this paper. The effect of this impact is often prominent in the design phase of the re-entry project to determine the maximum force for material strength determination to ensure structural and eq…
Cryo-transmission electron microscopy (Cryo-TEM) and particularly single particle analysis is rapidly becoming the premier method for determining the three-dimensional structure of protein complexes, and viruses. In the last several years there have been dramatic technological improvements in Cryo-TEM, such as advance…
Nanofluids consist of nanoparticles suspended in a liquid medium and the particle size is smaller than 100 nm.Nanofluids have great thermo-physical properties such as thermal conductivity, thermal diffusivity, viscosity and heat transfer coefficient as compared to their base fluids.The key feature of nanofluid is its…
The conical glass nanopore was modified through layer-by-layer electrostatic deposition of a monolayer of glucose oxidase, and then an ultrathin gold film was formed in situ through enzyme-catalyzed reactions. The morphology and components of single glass nanopore before and after ultrathin Au deposition were characte…
The nanoscale electro‐reduction in a memristive oxide is a highly relevant field for future non‐volatile memory materials. Photoemission electron microscopy is used to identify the conducting filaments and correlate them to structural features of the top electrode that indicate a critical role of the three phase bound…
Perylenes are well‐known pigments with excellent chemical, thermal, and photochemical stabilities and have been used in various optical and electronic fields. Although for sensitized mesoscopic solar cells there is rapid progress of metal‐free thiophene dyes, which now reach over 11.5% power conversion efficiency (PCE…
In this work, we report the synthesis of an three-dimensional (3D) cone-shape CNT clusters (CCC) via chemical vapor deposition (CVD) with subsequent inductively coupled plasma (ICP) treatment. An innovative silicon decorated cone-shape CNT clusters (SCCC) is prepared by simply depositing amorphous silicon onto CCC via…
Reinforced concrete flat slab structures are used widely in construction projects due to their economic and functional advantages. Punching shear failure in such structures can have catastrophic effects in the case of, for example, multi-storey framed structures and the designer aims to ensure that ductile flexural de…
Benzimidazoline radical dimers that can be handled in air but that function as powerful reductants are reported and evaluated as n-dopants by solution- and vacuum processing. In several host materials, one of these dimers is found to have a more-consistent doping effect than a hydride-donor dopant analog. Notably, a r…
Biobased composites have been widely proposed in the literature as suitable replacements for a variety of engineered materials, with applications ranging from biomedical devices to automotive components to construction materials. Previous research has primarily focused on engineering biobased alternatives with mechani…
ABSTRACT A polystyrene‐block‐poly(methyl methacrylate) (PS‐b‐PMMA) exhibiting a well‐defined structure was prepared combining anionic polymerization and mercaptan/ε‐caprolactam living polymerization. To evaluate how this block copolymer affected the crystallization of polylactide (PLA), 0.5 wt % thiol‐terminated PS ho…
Abstract Chemical modification based on incorporation of flame retardants into polymer backbones was used in order to reduce flammability of polystyrene (PSt). The halogeno‐substituted styrenes: 4‐chlorostyrene (ClSt), 4‐bromostyrene (BrSt) and 2,3,4,5,6‐pentafluorostyrene (5FSt) were applied as reactive flame retarda…
ABSTRACT The aim of this study was to investigate chitosan film behavior during microwave heating for 10 different heating times from 0 to 40 min. Chitosan films were produced by casting. Their structure and properties were investigated with several techniques, including Fourier transform infrared spectroscopy and dif…
A chromatographic adsorption unit was designed and built to study the adsorption of alkanes in zeolites for the hydrocarbon trap systems in three‐way catalysts, to assist in the selection of optimal materials for this application. The experimental apparatus used a zeolite bed in place of the column in an ordinary gas…
High-performance optoelectronic devices based on cup-stacked carbon nanotubes are realized. Based on a Schottky barrier model, rectifying behaviors and high photoresponse are observed by using growth catalysts as nanoscale electronic contacts. Similar performances are also obtained and furthermore tuned by using the…
Rubber nanocomposites based on styrene–butadiene rubber (SBR) and organophilic layered silicate were prepared. Clay structures based on dodecyl benzene sulfonic acid (DBSA), nonyl phenol ethoxylate (NPE), and DBSA/NPE (50/50%) were prepared and characterized. The results indicate the intercalation of the used surfacta…
In this paper, the spalling causes of backup rolls in a roughing mill of a hot strip rolling mill were investigated. The roughing mill withstood extreme service conditions with long service cycles for backup and work rolls, a large variety of the same width rolling campaigns, severe and non‐uniform wear contours of ba…
Biodegradable poly(butylene succinate) (PBS)/carbon fiber (CF) composites were prepared by melt blending method using twin‐screw extruder followed by injection molding. Mechanical properties, crystallization behavior, morphology, crystal structure, and thermal stability of PBS/CF composites were investigated with diff…
Gold nanoparticles have received much attention in recent years due to their unique size-dependent properties, as they find useful applications in materials science [Mayoral et al. (Nanoscale 2:335–342, 2010 )], catalysis [Schwerdtfeger (Angew Chem Int Ed 42:1892–1895, 2003 )] [Hashmi and Hutchings (Angew Chem Int Ed…
