Determination of Bromine in Brine by Wavelength Dispersive X-ray Fluorescence Spectrometry with Film Adsorption Pretreatment

open access: yesYankuang ceshi, 2015
Bromine exists mainly as ions in bromide brine and halide sulfate brine in the hydrosphere of the crust. Powder carrier pellet method is commonly used in analyzing bromine in brine by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). However,

Design of nanoparticles for generation and stabilization of CO2-in-brine foams with or without added surfactants [PDF]

open access: yesarXiv, 2018
Whereas many studies have examined stabilization of emulsions and foams in low salinity aqueous phases with nanoparticles (NPs) with and without added surfactants, interest has grown recently in much higher salinities relevant to subsurface oil and gas applications.

A step function density profile model for the convective stability of CO2 geological sequestration [PDF]

open access: yesarXiv, 2017
The convective stability associated with carbon sequestration is usually investigated by adopting an unsteady diffusive basic profile. The method of normal modes is not applicable due to the time dependence of the nonlinear base profile. Therefore, the instability is quantified either in terms of critical times at which the boundary layer instability ...

Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

3D Printing of Auxetic Self‐powered Mechanoluminescent Photonic Skins for Underwater Communication and Safety Monitoring

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed self‐powered auxetic mechanoluminescent photonic skin for underwater communication and safety monitoring is introduced. Its auxetic structures, with a negative Poisson's ratio, ensure exceptional conformability to curved surfaces, enhancing adaptability to dynamic underwater environments.
