Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Simulation of Vibration Caused by Blasting for a Layered Slope [PDF]

, 2004
Recent studies showed that vibration caused by blasting mainly reflects the property of geological structure itself neighboring the blasting center. Different vibration signals can be collected for different geological structures under blasting.

Numerical modelling of vibrational effects on buildings from blasting

, 2023
It is well known that blasting in rock may cause structural damages to nearby buildings. There are various national standards that regulate acceptable blast induced vibration levels. These standards are sometimes criticized for being outdated with a need

Properties of Surfactant-Modified Ammonium Nitrate

Gaoya wuli xuebao
Porous ammonium nitrate is frequently used for specific applications due to its porous structure when compared with conventional ammonium nitrate, however, its higher transportation costs increase overall operational expenses. This study investigated the

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Source Model for Blasting Vibration

, 2002
By analyzing and comparing the experimental data, the point source moment theory and the cavity theory, it is concluded that the vibrating signals away from the blasting explosive come mainly from the natural vibrations of the geological structures near ...

Effects of simulated blasting on mortality of Rainbow Trout eggs

, 2008
Blasting in or near water can negatively affect fish. In Canada, there are maximum allowable limits for blasting-induced overpressure (100 kPa) and peak particle velocity (PPV; 13 mm/s) to protect fish and their incubating eggs, respectively. No studies,
