The mechanical properties of foam concrete with sand at different low temperatures and different strain rates were studied. Foam concrete with sand at low temperatures (−10, −20, and −30°C) were tested using a split Hopkinson pressure bar (SHPB) apparatus with different impact pressures...
Scale bars: c 100 nm; d 20 nm; e 100 nm; f 200 nm. Full size image Here, we show that the Turing structure with near zero strain semi-coherence interfaces are constructed in homogeneous solutions subject to the diffusion kinetics. Our experimental results combined with molecular ...
13)C NMR2D NMR1-phenyl-1H-pyrazolesin molecular glasses of decalin, -terphenyl and toluene, and in polymethylmethacrylate polymer were obtained under continuous light illumination. Temperature was high enough so that the EPR spectra corresponded to thermal equilibrium between the spin sublevels. The...
It is noted that the reference heat should also be applied from the bottom electrode (via C and D) and the ratio between the HFS signal from the top and bottom heater should be averaged if the EC film thickness is much larger than the thermal diffusion length of the system. Utilizing ...
Differential scanning calorimetry (DSC) testing was employed to elucidate the crystal-glass transformation. As depicted in Fig.2d, during the initial up-scan, a notable endothermal peak at 140.7 °C emerges, denoted as the melting temperature (Tm), indicating the transition from a crystalline...
The challenge in accelerometer design is an accelerometer that responds only to acceleration along its sensing axis while rejecting all other mechanical, thermal, and electrical inputs. Pyroshock is a complex environment with acceleration along all axes, large dynamic strain ...
