Critical Review on the Molecular Behavior of Surfactants at the Oil–Water Interface During Oil Displacement

open access: yesEnergy Science &Engineering, EarlyView.
This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Nonthermal Food Processing Technologies: A Comprehensive Review

open access: yesFuture Postharvest and Food, EarlyView.
The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

Malleostapedotomy in Patients With Stapes Fixation: A Systematic Review

open access: yesThe Laryngoscope, EarlyView.
This systematic review analyses the current evidence on malleostapedotomy as a primary or revision procedure in patients with stapes fixation. Twenty‐five studies comprising 632 operated ears were included. Malleostapedotomy proved to be a safe and effective alternative to incus‐anchoring stapedoplasty, with favorable hearing outcomes and a low ...

An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...
