Synthesis and diverse biological activity profile of triethylammonium isatin-3-hydrazones

open access: yesADMET and DMPK, 2022
A series of biorelevant triethylammonium isatin hydrazones containing various substituents in the aromatic fragment have been synthesized. Their structure and composition were confirmed by NMR- and IR-spectroscopies, mass-spectrometry and elemental ...

Nickel(0)‐Catalyzed [2+2+2] Cycloadditions of Linked Bisdiynes with Diaryl Alkynes Generates D‐π‐A‐π‐D Bis(arylethynyl)indane‐Based Organic Frameworks as Noncytotoxic Probes for Ds‐DNA/Ds‐RNA

open access: yesChemistryEurope, Volume 4, Issue 4, April 2026.
Ni(0)‐catalyzed [2 + 2 + 2] cycloadditions of linked bisdiynes with diarylacetylenes generate highly fluorescent D‐π‐A‐π‐D bis(arylethynyl)indane dyes. They bind strongly to ds‐DNA and ‐RNA leading to significant fluorescence quenching, are nontoxic toward human cell lines, and have potential as multimodal fluorescence, CD, and Raman probes for ...

A Unified Mechanism on the Formation of Acenes, Helicenes, and Phenacenes in the Gas Phase. [PDF]

open access: yes, 2020
A unified low-temperature reaction mechanism on the formation of acenes, phenacenes, and helicenes-polycyclic aromatic hydrocarbons (PAHs) that are distinct via the linear, zigzag, and ortho-condensed arrangements of fused benzene rings-is revealed. This

Structure–Property Correlation of Diacylglycerol‐Modified Lipid Bases: Crystallization and Dispersion Behaviors

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
Medium‐chain diacylglycerols were incorporated into fully hydrogenated palm kernel oil stearin (FHPKS) to regulate crystallization behavior and melt–dispersion performance. Low DAG levels (5%–10%) promoted β′‐rich crystal networks and improved thermal responsiveness, establishing a structure–property framework for designing functional lipid bases ...

Characterization of biosurfactants’ micelles formation using fluorescence measurements: sodium taurocholate as case of study

open access: yesADMET and DMPK
Background and purpose: The evaluation of micellization parameters of surfactants that aggregate gradually, such as bile salts, is not trivial. In this work, different probes and data treatment models are tested to set up an analytical method based on ...

Design of a Reconfigurable Microfluidic System Enabled by Magnetic Miniature Robots

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Magnetic miniature robots are integrated into microfluidic chips to achieve real‐time reconfiguration. By external magnetic actuation, the robots perform sorting, mixing, flow regulation, and bubble removal on demand. This versatile platform eliminates the need for complex on‐chip hardware and enables adaptive control for biological and chemical ...
