A thermodynamic approach for correlating the solubility of drug compounds in supercritical CO2 based on Peng-Robinson and Soave-Redlich-Kwong equations of state coupled with van der Waals mixing rules [PDF]
Journal of the Serbian Chemical Society, 2019 In the present study, the effect of equations of state and mixing rules in a thermodynamic approach has been investigated for the correlation of the solubility of four new solid pharmaceutical compounds, namely, benzamide, cetirizine, metaxalone and ...

The legacy of van der Waals [PDF]
, 2015 The physical implications of the form and nature of the van der Waals equation of state are explained. The relation of this equation to so-‐‐called van der Waals forces and radii is ...

Advanced Functional Materials, EarlyView.A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Thermodynamics of Natural Pigment-Doped Ethanol under Monochromatic Laser Irradiation
Reviews on Advanced Materials Science, 2018 A laser beam heats a mixture of ethanol and anthocyanins producing the effect of a reciprocating machine. This behaviour is analyzed in terms of the stable, metastable and unstable states of Landau and Lifschitz.

Advanced Functional Materials, EarlyView.USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.

Evaluation of van der Waals density functionals for layered materials [PDF]
, 2018 © 2018 American Physical Society. In 2012, Björkman et al. posed the question "Are we van der Waals ready?" [T. Björkman, J. Phys.: Condens. Matter 24, 424218 (2012)JCOMEL0953-898410.1088/0953-8984/24/42/424218] about the ability of ab initio modeling to

Advanced Functional Materials, EarlyView.A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)
