Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications

Advanced Intelligent Systems, EarlyView.
Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

Stacking Interactions: A Supramolecular Approach to Upgrade Weak Halogen Bond Donors

Chemistry – A European Journal, Volume 28, Issue 70, December 15, 2022., 2022
π‐Stacking interactions turn on halogen σ‐hole in unactivated chloro‐ and bromo‐arenes which are thus enabled to function as good halogen bonding donors. Abstract The co‐crystallization of tetracyanobenzene (TCB) with haloarenes ArX provided six new co‐crystals TCB ⋅ ArX (ArX=PhCl, PhBr, 4‐MeC6H4Cl, 4‐MeC6H4Br, 4‐MeOC6H4Cl, 1,2‐Br2C6H4) which were ...

Enantioselective Photochemical Generation of a Short‐Lived, Twisted Cycloheptenone Isomer: Catalytic Formation, Detection, and Consecutive Chemistry

Angewandte Chemie, EarlyView.
In a proof‐of‐concept study, it was for the first time shown that planar chiral trans‐cycloalk‐2‐enones, such as 2, can be formed enantioselectively from their cis‐isomers by triplet energy transfer from a chiral catalyst. Computational studies performed with cyclohept‐2‐enone and enone 1 provided invaluable insights into the mode of action of the ...

Description of unilateral kidney embolism and contralateral nephrectomy as a less invasive remnant kidney model in cats; a proof‐of‐concept study

Animal Models and Experimental Medicine, EarlyView.
Unilateral, minimally invasive, renal arterial embolization and delayed contralateral nephrectomy was described in cats as a novel remnant kidney model of chronic kidney disease using two doses of embolic particles. Renal function declined and characteristic histopathological markers of kidney disease were present 6 months after the embolism procedure.

Synthesis of Cyclic and Acyclic ortho‐Aryloxy Diaryliodonium Salts for Chemoselective Functionalizations

Chemistry – A European Journal, Volume 28, Issue 69, December 9, 2022., 2022
Ortho‐iodo diaryl ethers are selectively transformed into either oxygen‐bridged cyclic diaryliodonium salts or ortho‐aryloxy‐substituted acyclic diaryliodonium salts through regioselective and high‐yielding one‐pot routes. A series of chemoselective arylations under metal‐catalyzed and metal‐free conditions shows the complimentary reactivities of these

Aqueous Zinc‐Bromine Battery with Highly Reversible Bromine Conversion Chemistry

Angewandte Chemie, EarlyView.
ZnSO4 solution is initially screened as the electrolyte for bromide cathodes. Subsequently, a targeted sequestration strategy is proposed to modify KBr cathode, achieving high‐reversibility bromine conversion chemistry. In situ Raman spectra reveal a Br3−/Br−‐dominated conversion mechanism.

Specific Lipid Studies in Complex Membranes by Solid‐State NMR Spectroscopy

Chemistry – A European Journal, Volume 28, Issue 70, December 15, 2022., 2022
Specific lipid interaction in complex membranes: Specific interactions with lipids are critical for proteins and drugs, however, direct structural measurements of interactions with lipids remain difficult, especially in membranes that mimic biological conditions.
