Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

Advanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing

Red‐Light Tomographic Volumetric 3D Printing in Seconds for Fabrication of Colorless Structures

Advanced Materials Technologies, EarlyView.
A custom red‐light‐responsive TVAM platform combines methylene blue, triethanolamine, and PEGDA to fabricate transparent crosslinked hydrogels. Light patterns are projected into a rotating resin container, where a sacrificial photoinitiator system enables rapid polymerization and colorless channel‐containing structures, utilizing low‐energy light for ...

Square lattice Ising model \tilde{\chi }^{(5)} ODE in exact arithmetic [PDF]

Journal of Physics A: Mathematical and Theoretical, 2010
We obtain in exact arithmetic the order 24 linear differential operator $L_{24}$ and right hand side $E^{(5)}$ of the inhomogeneous equation$L_{24}(Φ^{(5)}) = E^{(5)}$, where $Φ^{(5)} =\tildeχ^{(5)}-\tildeχ^{(3)}/2+\tildeχ^{(1)}/120$ is a linear combination of $n$-particle contributions to the susceptibility of the square lattice Ising model. In Bostan,

A Transnasal Endoscope for Robotically Assisted Gastroscopy

Advanced Robotics Research, EarlyView.
This work introduces a 4.25 mm diameter magnetically navigated transnasal endoscope for upper gastrointestinal (GI) screening and intervention. The system enables precise remote steering throughout the upper GI tract and is demonstrated through in vitro and in vivo experiments, including the robotic execution of preprogrammed retroflexions, trans ...

Disrupted TFEB/GDNF–cAMP/ATP Coupling Underlies Astrocytic Dysfunction and Depression in LRRK2 G2019S Parkinson's Mice

Advanced Science, EarlyView.
ABSTRACT The LRRK2 G2019S mutation, a Parkinson's disease–linked variant, has been associated with depression‐like phenotypes, but mechanisms remain unclear. We chart age‐dependent behavioral changes and astrocyte reactivity in G2019S mice and define a pathway connecting LRRK2 to TFEB/GDNF signaling, cellular energetics, and inflammation.
