Mechanical Caging of Nucleic Acids Enabled by Light‐Activated Synthetic Molecular Motors

Angewandte Chemie, EarlyView.
A synthetic light‐driven molecular motor imposes mechanical constraints on nucleic acids, enabling “mechanical caging” as a new mode to regulate DNA structure and function through mechanical input rather than chemical masking. ABSTRACT Control over nucleic acid activity is central to biotechnology and therapeutic development.

Patient‐Mounted Neuro Optical Coherence Tomography for Targeted Minimally Invasive Micro‐Resolution Volumetric Imaging in Brain In Vivo

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a patient‐mounted neuro optical coherence tomography system that integrates a 5 degrees‐of‐freedom skull‐mounted robot (Skullbot) with a 0.6 mm neuroendoscope for targeted, minimally invasive deep brain imaging, is developed. The system offers high‐resolution imaging with precise deployment, demonstrated through successful tumor imaging in a ...

Contact Force Estimation in Human–Robot Collaboration: A Case Study on Heavyweight Robotic Manipulators

Advanced Intelligent Systems, EarlyView.
The method presented in this paper provides a practical sensorless solution for estimating both contact force and contact location using only standard joint encoders and an available robot dynamic model. By reformulating the contact estimation problem using a single scalar equivalent contact parameter, the approach enables fast and robust computation ...

Light‐Enhanced Chloride Transport by Thiourea‐Appended Molecular Motor

Angewandte Chemie, EarlyView.
A molecular motor functionalized with a thiourea anion‐binding motif mediates transmembrane chloride transport. Light irradiation enhances transport efficiency by populating a more active metastable isomer, which slowly equilibrates to the initial stable isomer.

Short Sb···Sb Contacts in Polymorphic Tris(p‐Tolyl)Antimony: A Hallmark of Organoantimony(III) Solid‐State Chemistry?

Angewandte Chemie, EarlyView.
Discovery of polymorphism in solid tris(p‐tolyl)antimony(III) highlighted short, direct antimony‐antimony contacts, with interatomic separation shorter than the sum of the van der Waals radii, and calculated interaction energy of ca. 26 kJ mol−1 that includes a significant dispersion component.
