Influence of nanoparticle encapsulation and encoding on the surface chemistry of polymer carrier beads

open access: yesScientific Reports, 2023
Surface-functionalized polymer beads encoded with molecular luminophores and nanocrystalline emitters such as semiconductor nanocrystals, often referred to as quantum dots (QDs), or magnetic nanoparticles are broadly used in the life sciences as ...

Materials Testing [PDF]

open access: yes, 2008
In recent years, a number of models to calculate the acoustical behaviour of porous materials (sound absorption, sound insulation and vibration damping) have been developed [1]. Although these models are based on physical sound theories, they require a number of material parameters and the output of a calculation will depend on the accuracy of the ...

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

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.
