In general, the critical length of the damage zone depends on the material, specimen, and size of the sharp notch.
Meanwhile, experimental research on thermal insulation performance of a lightweight ceramic material specimen and a novel ceramic-nanomaterial hybrid structure in high-temperature/oxidation environments up to 1700 °C was carried out.
NICD conducted the following laboratory tests on 2 suspected culture isolates, 2 sputum specimens, 1 lung autopsy material specimen, and 1 lung lavage sample (Table): 1) direct fluorescent antibody test for Yersinia pestis; 2) culture and bacteriophage lysis test; and 3) PCR and gene sequencing to detect Y. pestis specific genes (pla and F1).
Existing research has investigated the fatigue properties of 3D printed multi-material specimens and shows that there is a weakness at multi-material interfaces.
The 3 other factors (material, specimen thickness, and surface) and all possible interactions among them were significant (P<.05).
Material specimens in vacuum and living cells in air can also be irradiated by this facility.
There were equal amounts of CFU recovered from root filling material specimens with PDT and the combination of NaOCl irrigation followed by PDT.
In order to determine strain rate effects and to draw conclusions about the hydrostatic stress dependency of the material, specimens were tested in compression and tension at strain rates from 10−3 to 104 s−104
As an efficient, space-saving method to cool the container and the material specimens, an array of mini-channels (1 mm gaps) through which low pressure (0.3 MPa) helium gas is flowing is established.
Material specimens were subjected to electrochemical and long-term incubation test with artificial tear fluid (ATF) of various acidities.
And more dimples appear for material specimens.
