Modeling the Viscosity of Anhydrous and Hydrous Volcanic Melts
The viscosity of volcanic melts is a dominant factor in controlling the fluid dynamics of magmas and thereby eruption style. It can vary by several orders of magnitude, depending on temperature, chemical composition, and water content. The experimentally

State determination of catalytic converters based on an ultra-wideband communication system [PDF]
A novel microwave-based approach for monitoring the state of aftertreatment systems such as diesel particulate filters (DPFs), three-way catalytic converters (TWCs), and selective catalytic reduction (SCR) catalysts is proposed.

Periodic patterns displace active phase separation
In this work we identify and investigate a novel bifurcation in conserved systems. This secondary bifurcation stops active phase separation in its nonlinear regime. It is then either replaced by an extended, system-filling, spatially periodic pattern or,

Functionalized DNA-spider silk nanohydrogels for controlled protein binding and release
Hydrogels are excellent scaffolds to accommodate sensitive enzymes in a protective environment. However, the lack of suitable immobilization techniques on substrates and the lack of selectivity to anchor a biocatalyst are major drawbacks preventing the ...

Metal foam electrodes are promising for efficient CO2 reduction, but detailed characterizations of the foams at the macro and nanoscale are lacking. Here, the authors combine physicochemical and microscopic techniques in conjunction with electrochemical ...

Nonlinear spectroscopy of plasmonic nanoparticles
The plasmon resonance of a metal nanoparticle increases the optical field amplitude in and around the particle with respect to the incoming wave. In consequence, optical effects that are nonlinear in their field amplitude profit from this increased field.

Dauphiné twin in a deformed quartz: characterization by electron channelling contrast imaging and large-angle convergent-beam diffraction [PDF]
A Dauphiné twin (DT) in a deformed quartz was visualized for the first time by using orientation-optimized electron channelling contrast imaging (ooECCI) under Bragg conditions of the rhombohedral planes. The visualization in backscattered electron (BSE)

Meso-Structuring of SiCN Ceramics by Polystyrene Templates
A simple one-pot synthesis of well-defined PS-silazane nano-composites (polystyrene, PS) is described. In contrast to the, thus far, used two-step procedure ((1) assembly of a PS template bed and (2) careful filling of the voids between the PS spheres),

Hierarchical structures are abundant in almost all tissues of the human body. Therefore, it is highly important for tissue engineering approaches to mimic such structures if a gain of function of the new tissue is intended.
