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

open access: yesSmall, 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

open access: yesSmall, 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.

Symmetry‐Guided Optical Control of Dynamic 1D Protein Self‐Assembly and Precise In Vitro Initiation of Biomolecular Condensation

open access: yesSmall, EarlyView.
A photoreversible 1D protein assembly has been developed by utilizing symmetry matching between StrepTactin and photoswitchable Dronpa145N. The light‐induced modulation of oligomerization allows for precise control over protein connectivity and valency.

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

open access: yesSmall, 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

open access: yesSmall, 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 ...

Chemical and Biological Determinants of PEG‐Lipid Shedding From Therapeutic Nanoparticles

open access: yesSmall, EarlyView.
PEG‐lipids play a central role in governing lipid nanoparticle stability, targeting, and function. However, PEG‐lipids can “shed” from the nanoparticle surface in biological environments, with the extent and kinetics of shedding influenced by chemical and biological factors.

Harnessing the Folding of Antitumor Peptides for Controlled Carrier‐Free Drug Delivery

open access: yesSmall, EarlyView.
A disulfide‐bridged stapled p53 α‐helix co‐assembled with doxorubicin into protease‐resistant nanocomplexes. Reductive intracellular conditions induced helix refolding and nanostructure disassembly, which enabled the coordinated release of the chemotherapeutic agent and anticancer peptide.

Nanosecond, Nanometer Movies of MEMS/NEMS Dynamics in a Standard SEM Using Time‐Tagged Secondary Electrons

open access: yesSmall Methods, EarlyView.
For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

The Influence of the Pretreatment of Tool Steel on the Running‐In Phase of Diamond‐Like Carbon Coatings

open access: yessteel research international, EarlyView.
The influence of tool steel pretreatment on the running‐in behavior of TiNb‐diamond‐like carbon (DLC) coatings is investigated. Ion etching promotes carbide protrusion and increases coating roughness, while post‐deposition polishing reduces surface asperities.
