Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

Advanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Dual-energy micro-CT of the rodent lung

American Journal of Physiology-Lung Cellular and Molecular Physiology, 2012
The purpose of this work is to investigate the use of dual-energy micro-computed tomography (CT) for the estimation of vascular, tissue, and air fractions in rodent lungs using a postreconstruction three material decomposition method. Using simulations, we have estimated the accuracy limits of the decomposition for realistic micro-CT noise levels ...

Micro-accounting for Optimizing and Saving Energy in Smart Buildings [PDF]

, 2016
Energy management, and in particular its optimization, is one of the hot trends in the current days, both at the enterprise level (optimization of whole corporate/government buildings) and single citizens' homes. The current trend is to provide knowledge about the micro(scopic) energy consumption.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Polyphenylalanine-Modified Electrode Enabled Sensitive and Selective Detection of Cadmium Ions in Environmental Water

Digest Journal of Nanomaterials and Biostructures
A novel electrochemical sensor for cadmium ions (Cd2+) was fabricated by electropolymerizing L-phenylalanine on a glassy carbon electrode (PPhe/GCE). The resulting polyphenylalanine (PPhe) film combines a conductive polymer backbone with abundant amino ...

The Growth of Micro-organisms in Relation to their Energy Supply

Microbiology, 1960
SUMMARY: When Streptococcus faecalis was grown anaerobically in a complex medium containing d-glucose, d-ribose or l-arginine as energy source the dry wt. of organism produced was proportional to the concentration of the energy source in the medium. However, S. faecalis will not grow in a defined medium with arginine as the energy source unless glucose

Study of Inertia and Damping Characteristics of Doubly Fed Induction Generators and Improved Additional Frequency Control Strategy

Energies, 2018
Large-scale wind farms connect to the grid and deliver electrical energy to the load center. When a short-circuit fault occurs on the transmission line, there will be an excess of electric power, but the power demand will increase instantaneously once ...
