Using angle-resolved photoelectron spectroscopy we investigate the electronic valence band structure of the Si(331)-(12 × 1) surface reconstruction for which we recently proposed a structural model containing silicon pentamers as elementary structural buil ...
Polyiodides have been transferred intact from acetonitrile solution to the gas phase and analyzed by mass spectrometry. A range of ions were observed, including I-11, I-13, and I-15, which have higher iodine/iodide ratios than any previously ...
In general, most porous materials are so complex that structural information cannot be easily observed with 3D visualization tools. To address this problem, we have developed a special abstract 2D representation to depict all important topological features ...
Ultrasonic assistance is widely used in manufacturing, both for conventional (e. g. grinding, drilling) and non-conventional (e. g. EDM) processes. Ultrasonic machining is also used as a stand alone process for instance for micro-drilling. Industrial appli ...
Structural fire endurance experiments were conducted on full-scale cellular glass fiber reinforced (GFRP) columns under axial compression and subjected to ISO 834 fire exposure from one side. Unprotected columns could resist fire for more than 30 min, whic ...

The multifunctional use of FRP composites offers the potential to contribute to the emergence of a new generation of lightweight engineering structures for an innovative infrastructure that meets the challenges with which today's construction industry is f ...

Re-protonation is key: A combination of a high magnetic field (1 GHz) and ultra-fast magic-angle spinning (60 kHz) allows easy detection of NMR spectra revealing details of secondary and tertiary structures of medium-sized proteins. The technique was appli ...
We introduce a nonradial potential term for coarse-grained (CG) molecular simulations of proteins. This term mimics the backbone dipole−dipole interactions and accounts for the needed directionality to form stable folded secondary structure elements. We sh ...
Simulation is a key issue in the design of control electrical systems. Simulation packages using component library, such as PSIM®, are very useful to achieve this goal. The simulation model is thus easily built from the system topology (structural model). ...
The influence of the constant life diagram (CLD) formulation on the fatigue life prediction of composite materials was examined. Most commonly used and recently proposed CLDs applied on composite materials fatigue data are presented and their applicability ...
