Multidimensional shearforce-based constant-distance mode scanning electrochemical microscopy (4D SF/CD-SECM) was utilized for the investigation of the activity distribution of oxygen reduction catalysts. Carbon-supported Pt model catalyst powders have been immobilized in recessed microelectrodes and compared to a spot preparation technique. Microcavities serve as platform for the binder-free ca...

We present a detailed Monte Carlo study of the high-temperature phase of the two-dimensional driven lattice gas at infinite driving field. We define a finite-volume correlation length, study its finite-size-scaling behavior and extrapolate it to the infinite-volume limit by using an iterative extrapolation method. The same method is applied to the susceptibility. We determine the transverse exp...

In affinity proteomics, specific protein-binding molecules (a.k.a. binders), principally antibodies, are applied as reagents in proteome analysis. In recent years, advances in binder technologies have created the potential for an unprecedented view on protein expression and distribution patterns in plasma, cells and tissues and increasingly on protein function. Particular strengths of affinity ...

Asphalt pavements undergo long-term aging due to oxidation of the asphalt binder. As a pavement oxidizes, it stiffens and eventually cracks. The use of an antioxidant in an asphalt binder could retard aging, thus increasing the pavement’s service life. Lignin is a known antioxidant and is highly available from timber and many agricultural products. A wet-mill ethanol process produces several co...

Self-consolidating concrete (SCC) mixtures designated for precast, prestressed applications should be highly workable to flow easily through restricted spacing and completely encapsulate reinforcements without any mechanical vibration. Key workability characteristics of SCC can be described in terms of filling ability, passing ability, and resistance to segregation. These properties are typical...

This article addresses the design of a self-compacting gypsum-based lightweight composite (SGLC). A β-hemihydrate is used as binder and lightweight aggregate (LWA, 0-2 mm in different size ranges) is used as aggregate into this composite. The mix of the new composite is designed based on the particle size distribution grading theory applying the modified Andreasen and Andersen (A&A) grading lin...

Opportunistic pathogen Aggregatibacter actinomycetemcomitans resides in the multispecies biofilm in dento-gingival junction. A. actinomycetemcomitans binds and uptakes human proinflammatory cytokines, which may increase the bacterial virulence. Outer membrane secretin channel (here OMS), a DNA binder, is involved in uptake of DNA by A. actinomycetemcomitans. However, OMS homologue in Neisseria ...

Porous, nanostructured Li(NixCoyMn)O2 (NCM) achieves an improvement in the fast-charging capability and durability of lithium-ion batteries. This is attributed to extended electrolyte—active material interface, where electrochemical reactions take place thus shorter diffusion paths inside active particles are necessary for charge transfer. Due porous particle morphology, new processing challeng...

Abstract The present study investigates the feasibility of using two types municipality solid wastes incineration ashes, namely, fly ash and bottom in production sustainable alkali-activated binder. ashes are collected from plant characterized to determine their particle size distribution, specific gravity, chemical composition, heavy metals content. then used as either or sand replacement with...
