An ultrafiltration unit with a polyvinylidene fluoride (PVDF) membrane of 40 nm nominal pore size was used to study bacteriophage MS2 removal under different conditions: pristine membrane, fouled by soluble microbial product (SMP) extracted from bioreactor (MBR) feedwater, backwashed and chemically cleaned membrane. The order these membranes as follows: > ≈ A linear correlation between relative permeability found. Mass balance analysis showed high percentage in the concentrate for compared...
Focused ion beam lift-out has become an essential technique for fabricating small-scale specimens in atom probe tomography (APT). By using a rotatable micromanipulator, we developed methods that can precisely extract the regions of interest APT samples with challenging-to-prepare geometries. Combining this function pre-milling and pre-tilt operations, prepare three typically challenging specimens: nanoparticles, nanowires, thin films. This combination effectively decrease sample preparation...
Hydroxyapatite (HAP) is a cost-effective material to remove excess levels of fluoride from water. Historically, HAP has been considered adsorbent in the environmental engineering community. This paper substantiates an uptake paradigm that recently gained disparate support: assimilation bulk apatite lattice sites addition surface sites. Pellets nanoparticles (NPs) were packed into fixed-bed media filter treat solutions containing 30 mg-F/L (1.58 mM) at pH 8, yielding 15.97 ± 0.03 mg-F/g-HAP...
Abstract Hydroxyapatite nanoparticles (HAP NPs) are important for medicine, bioengineering, catalysis, and water treatment. However, current understanding of the nanoscale phenomena that confer HAP NPs their many useful properties is limited by a lack information about distribution atoms within particles. Atom probe tomography (APT) has spatial resolution chemical sensitivity NP characterization, but difficulties in preparing required needle‐shaped samples make design these experiments...
