A Soft Robotic Device for Targeted Massage Therapy of Residual Limbs

open access: yesAdvanced Robotics Research, EarlyView.
Residual limb edema after amputation can hinder recovery and delay prosthetic fitting. This study presents a soft‐robotic wearable device that delivers sequential compression through pneumatic McKibben actuators. By replicating the principles of manual lymphatic drainage, the device generates controlled mechanotherapeutic pressure patterns, providing a

Natural Products Inspired Scaffold Diversification Leads to Unnatural Molecular Warhead and Covalent Strategy to Modulating Protein Function through Electrophilic Bromine Transfer

open access: yesAdvanced Science, EarlyView.
We report a new thiolate‐reactive α,α‐gem‐dibromo lactam warhead that activates transcription factor Nrf2 and demonstrates anti‐inflammatory activities, which have implications in cancer, neurodegeneration, and cardiovascular diseases. RNA‐seq illuminated detailed transcriptional profiles, and chemical reactions with cysteine‐containing compounds ...

Conversion of Alcohols into Amides Using Alumina-Methanesulfonic Acid (AMA) in Nitrile Solvents [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
The reaction of tertiary, secondary and benzylic alcohols with different nitriles in the presence of alumina-methanesulfonic acid (AMA) as a new reagent affords the corresponding amides in good yields (Table 1, 2).

Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

open access: yesAdvanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Dynamic dielectric properties and the γ transition of bromine doped polyacrylonitrile

open access: yeseXPRESS Polymer Letters, 2007
Based on monitoring the γ process (the lowest temperature-relaxation) in polyacrylonitrile (PAN) by dynamic dielectric spectroscopy, new evidence for the formation of a charge transfer complex between bromine dopants and nitrile groups is presented.

Momentum Transfer Rate Constants for Collision of Cl-with Trans-Dichloroethylene and Para-Difluorobenzene [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
A classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. The model takes into consideration the effect of diffraction outside the capture limit on the rate constants. The theory is used

Electrochemistry of 2,2'-Bipyridine Complexes of Cobalt in the Presence of Acrylonitrile [PDF]

open access: yes, 1978
The previously claimed (1) catalysis of the electroreduction of acrylonitrile by means of a complex of Co(I) and 2,2′‐bipyridine is shown to be erroneous. The “catalytic currents” result instead from the two‐electron reduction of a mixed complex of Co(I)
