Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Endogenous Versus Exogenous Redox‐Mediators in Anaerobic Bioelectrochemical Systems: A Comparative Study With Pseudomonas putida

open access: yesChemElectroChem, Volume 13, Issue 10, 19 May 2026.
A comparative study of endogenous and exogenous mediators for bioelectrochemical systems is conducted. Ferricyanide and phenazine‐1‐carboxylic acid are selected as representative compounds, and their electrochemical and physiological impacts on Pseudomonas putida under comparable bioelectrochemical conditions are systematically evaluated.

Piperazine‐Functionalized Nanoparticles Enable Oral Insulin Delivery in Obese Mice

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
ABSTRACT Biologics have gained prominence as a rapidly advancing therapeutic modality for a diverse spectrum of medical conditions. Nonetheless, they are predominantly administered parenterally due to poor absorption through the gastrointestinal tract. Additionally, repeated injections of biologics such as insulin cause injection pain, leading to dose ...

Pollinator Visitation Alters Cranberry Flower Fungal Communities in Wisconsin Cranberry Agroecosystems

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
A two‐year study reveals shared fungal communities between cranberry flowers and insect visitors, including Apis mellifera, Bombus species, solitary bees and hover flies. Greater fungal richness was present in pollinator‐accessible flowers compared to those that were tented.

Liquid Metals as Initiators of Free‐Radical Polymerization of Hydrogels: A Perspective

open access: yesAdvanced Functional Materials, Volume 36, Issue 6, 19 January 2026.
Gallium‐based liquid metals initiate free radical polymerization to form hydrogels without the use of toxic molecular initiators. In addition to initiating polymerization, they can act as crosslinkers, yielding softer, more extensible, and tougher hydrogels than those formed with conventional initiators.

An Evaluation of the Physicochemical Properties of Stabilized Oil-In-Water Emulsions Using Different Cationic Surfactant Blends for Potential Use in the Cosmetic Industry

open access: yesCosmetics, 2019
One of the most complex problems in hair care formulations is the duality of the surfactants used. In this regard, such surfactants must be cationic so as to interact with the negatively charged cuticle surface of hair.
