Betulinic Acid Enema Alleviates Colitis by Targeting Vitamin D Receptor to Protect the Intestinal Mucosal Barrier and Modulate Mucosa‐Associated Microbiota

Phytotherapy Research, EarlyView.
ABSTRACT Ulcerative colitis (UC) is a chronic inflammatory disease of the colon with limited effectiveness and safety of current drug therapies. Betulinic acid (BA) is a naturally occurring pentacyclic triterpenoid present in traditional Chinese medicines used clinically as retention enemas for UC, but its direct effects and mechanisms remain unclear ...

Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

Small, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

Adhesive Protein Nanoparticles Control Emulsion Properties via Tunable Interdroplet Linking

Small, EarlyView.
In this study, pea protein nanoparticles were probed for their ability to link emulsion droplets. Experiments across multiple length scales showed that the nanoparticles form shear‐resistant links via bridging interactions from the thin film between droplets.

Interferometric Vector Piezoresponse Force Microscopy for Simultaneous Ferroelectric Domain and Crystallographic Orientation Mapping in Uniaxial Ferroelectric Polycrystals

Small, EarlyView.
Interferometric vector piezoresponse force microscopy is used to reconstruct crystallographic grain orientations in polycrystalline ferroelectrics directly from local electromechanical response. The approach reveals grain orientation, polarization direction, and domain structure simultaneously, establishing a pathway toward EBSD‐like orientation ...

Tailoring MXene Flake Morphology via Aerosol Jet Printing for Biological and Strain Sensor Applications

Small, EarlyView.
Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...
