Application of pyrophyllite in high-temperature treated building materials [PDF]

open access: yesScience of Sintering, 2023
Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures, making it a suitable mineral ...

NRL materials testing facility [PDF]

open access: yes2012 16th International Symposium on Electromagnetic Launch Technology, 2012
The Naval Research Laboratory Materials Testing Facility performs basic research on high-power railguns. The laboratory houses a 6-m-long, 5-cm-bore railgun capable of launching 0.5-kg projectiles at up to 2.5 km/s. The railgun is powered by an 11-MJ capacitor bank comprising twenty-two 0.5-MJ modules.

Laboratory tools to quantify biogenic dissolution of rocks and minerals: a model rock biofilm growing in percolation columns

open access: yesFrontiers in Earth Science, 2016
Sub-aerial biofilms (SAB) are ubiquitous, self-sufficient microbial ecosystems found on mineral surfaces at all altitudes and latitudes. SABs, which are the principal causes of weathering on exposed terrestrial surfaces, are characterised by patchy ...

Local Hydrogen Measurements in Multi-Phase Steel C60E by Means of Electrochemical Microcapillary Cell Technique

open access: yesMetals, 2023
By utilizing hydrogen as an eco-friendly energy source, many metals are exposed to gaseous (pressurized) hydrogen. High-strength steels with an ultimate tensile strength of 800 MPa and above are especially susceptible to hydrogen-induced fracturing, also

Complexity of the behaviour of asphalt materials in cyclic testing [PDF]

open access: yes, 2017
This paper compares the results obtained in two types of cyclic tension-compression tests, a time sweep test, constant strain amplitude, and a strain sweep test, increasing strain amplitude every 5000 cycles, called EBADE (standing for the Spanish words ...

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
