Adsorption of Mono Substituted Nitro Phenols From Aqueous Solution on the Zemeej Surface at Different Temperatures

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
   Adsorption of o-Nitrophenol (o-Nph), m- Nitrophenol (m-Nph) and p- Nitrophenol (pNph) on the sedimentary sand of the Tigress River which is known locally by “Zemeej” from aqueous solution at 288, 298, 308, 318 and 328 k0 .

Ultrasonic irradiation of p-nitrophenol in aqueous solution

open access: yes, 1991
The kinetics and mechanism of the sonochemical reactions of p-nitrophenol have been investigated in oxygenated aqueous solutions. In the presence of ultrasound (20 kHz, 84 W) p-nitrophenol was degraded primarily by denitration to yield NO_2^-, NO_3 ...

Second harmonic generation by p-nitrophenol at water/air and water/heptane interfaces

open access: yes, 1992
Interfacial second harmonic generation by p-nitrophenol at air/water and heptane/water interfaces has been investigated. The preliminary results indicate that the orientation of the p- nitrophenol is slightly different in the two cases. but the influence

Metal‐Dependent Effects and Crowding Robustness of Pseudomonas fluorescens Esterase I

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Pseudomonas fluorescens esterase I retains catalytic activity in metal‐rich and crowded environments, despite metal‐specific inhibitory effects. These findings highlight its robustness for biocatalytic applications in complex environments. Industrial biocatalysts are strongly influenced by their physicochemical environment, yet systematic studies on ...

Semi‐Rational Engineering of Formate Dehydrogenase Reveals Loop Dynamics as a Key Determinant of Thermostability

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Semi‐rational engineering yields a thermostable Bacillus simplex formate dehydrogenase variant (Q125F) with a 25‐fold longer half‐life at 60°C and strong resistance to chemo‐inactivation. Molecular dynamics reveal enhanced π–π interactions stabilizing a flexible loop and enabling efficient NADH regeneration for robust biocatalytic detoxification ...

Toward Reliable Spectroscopic Analysis of Reaction Kinetics in Polaritonic Chemistry

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
Vibrational strong coupling has been reported to modify chemical reaction rates, yet its mechanism remains unresolved. We expose pitfalls in UV/Vis‐based kinetic analyses and emphasize the need for standardized cavity protocols. ABSTRACT Recent reports suggest that chemical reaction rates can change inside an optical cavity.
