A Soft Robotic Jellyfish with Decoupled Actuators for Agile 3D Locomotion

Advanced Intelligent Systems, Volume 8, Issue 6, June 2026.
This study presents a soft robotic jellyfish featuring a functionally decoupled actuation architecture. By separating propulsion, steering, and vertical regulation into independent modules, the robot overcomes conventional coupled‐motion limitations. Utilizing a passive‐valve‐based differential drag strategy and lateral water jets, it achieves agile 3D

Modifying def2‐TZVPP: A Minimal Diffuse Addition for Reliable ΔE Versus ρ(BCP) Relationships in H‐Bonded Systems

Journal of Computational Chemistry, Volume 47, Issue 14, 30 May 2026.
Minimal hydrogen‐centered diffuse functions improve the description of the hydrogen‐bond critical point. ABSTRACT Basis set quality has a relevant role in the electronic structure description of hydrogen‐bonded (H‐bonded) systems, particularly for properties sensitive to the electron density in low‐density intermolecular regions.

Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

Chemistry – A European Journal, Volume 32, Issue 20, 27 May 2026.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...

Optimized Green Synthesis of Silver Nanoparticles Using Ocimum gratissimum Extract With Antibacterial and Antibiofilm Activity Against Multidrug‐Resistant Bacteria

ChemistrySelect, Volume 11, Issue 19, 20 May 2026.
ABSTRACT While several studies have explored the green production of silver nanoparticles (AgNPs), only a limited number have specifically investigated their antibacterial properties when synthesized using Ocimum gratissimum (OG) extracts as both a reducing and stabilizing agent.
