Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

open access: yesSmall, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.

Solvatochromism in Solvent Mixtures: A Practical Solution for a Complex Problem

open access: yesLiquids
Many reactions are carried out in solvent mixtures, mainly because of practical reasons. For example, E2 eliminations are favored over SN2 substitutions in aqueous organic solvents because the bases are desolvated.

The Host‐Guest Assemblies of Metal–Organic Frameworks and Protic Ionic Liquids With ZIF‐8 and [Dema][TfO] – Structural Response and Ionic Conductivity

open access: yesSmall, EarlyView.
MOFs can serve as effective proton conductors owing to their porous structures and well‐defined channels. In this study, the protic ionic liquid [Dema][TfO] is introduced into ZIF‐8 cages. The confined [Dema][TfO] can transfer between adjacent ZIF‐8 cages, inducing cage expansion through the swing effect.

Reverse Micelles: The Gateway for Oral (Poly)Peptide Delivery

open access: yesSmall, EarlyView.
RM achieve superior oral peptide delivery through high loading capacity, strong lipophilicity, and a low‐hydration microenvironment that protects against enzymatic degradation. Meanwhile, dRM provides favorable permeation‐enhancing interactions and a consistent safety profile, collectively driving enhanced oral performance.

ULTRASONIC STUDIES OF ANTIPROTOZOAL DRUG IN PROTIC AND APROTIC SOLVENTS AT 308.15 K

open access: yesLatin American Applied Research - An international journal, 2014
 Ultrasonic velocities and density of various concentrations (0.01 to 0.10M) of anti protozoal drog “Diloxanide Furoate” in methanol, dimethyl formamide and 1,4-dioxan have been measured at 308.15 K by using single crystal variable path ultrasonic interferometer operating at 2 MHz and pycnometer respectively.

1,4‐Brook Rearrangement of β‐Silyl Allylic Alcohols: Trisubstituted Alkenes by Copper‐Mediated Stereoretentive ipso‐Substitution Reactions

open access: yesAngewandte Chemie, Volume 138, Issue 44, 26 October 2026.
To fully leverage the power of the ruthenium‐catalyzed trans‐hydrosilylation of propargyl alcohols, it was necessary to develop a practical and robust method for the activation of those products that carry the silyl group distal to the hydroxy substituent.
