Alignment, Rising, Sticking, and Phototaxis: Modulating the Behavior of Hematite Micropeanuts

Advanced Materials Interfaces, Volume 12, Issue 9, May 5, 2025.
Although a rich variety of behaviors, such as rising and phototaxis, are observed with light‐activated semiconductor microparticles, the experimental conditions under which such behaviors occur have not been elucidated. In this study, pH, fuel concentration, and light intensity are varied, revealing diverse behaviors of hematite microparticles.

Fabrication of Schiff Base Interfacial Films via Polyethyleneimine and Glutaraldehyde for pH‐Responsive Oil‐in‐Water High Internal Phase Emulsions

Advanced Materials Interfaces, EarlyView.
Due to the Schiff base reaction between polyethyleneimine and glutaraldehyde in the aqueous phase, a pH‐responsive interfacial film is constructed at the interface of the two immiscible phases. Consequently, both pH‐reversible high internal phase emulsions and pH‐controlled release capsules can be easily fabricated using this emulsion system.

Antifouling PEG Coatings by Thiol‐Acrylate Conjugate Addition Reactions for Generation of Protein Patterns via Photobleaching‐Induced Protein Binding (PiPB) BioBitmaps Using Maskless Projection Lithography

Advanced Materials Interfaces, EarlyView.
Homo‐bifunctional PEG, acrylate‐PEG‐acrylate (PEGDA), coatings are prepared on glass and glass‐type surfaces using solvent‐free thiol‐acrylate conjugate addition reactions at room temperature. The prepared PEGDA coatings are stable, antifouling, and provide feature terminal acrylates that can act as free radical acceptors for photobleaching‐induced ...

Supramolecular Nanoarchitectonics of PNIPAAM‐co‐MA and Imogolite to Obtain Thermoresponsive Clay Nanotubes Through Complexation Mechanism

Advanced Materials Interfaces, EarlyView.
The selective adsorption of anionic poly(N‐isopropylacrylamide)‐co‐methacrylic (PNIPAAM‐co‐MA) onto the external surface of imogolite nanotubes is driven by electrostatic attractions. The copolymer coating affects the surface charge, aqueous diffusion and self‐assembling of imogolite.

Growth Factor‐Loaded Mesoporous Silica Particles, Incorporated in Electrospun PCL Fibres, Provide Topographical and Chemical Cues for Tendon Tissue Engineering

Advanced Materials Technologies, EarlyView.
Electrospinning enables the hierarchical assembly of nanofiber‐based scaffolds for tissue engineering. However, encapsulated proteins often undergo structural changes. This study used mesoporous silica nanoparticles (MSNs) as protective carriers, mitigating protein denaturation and supporting controlled release.

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

Advanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

An Analysis of Elusive Relationships in Floating Zone Growth Using Data Mining Techniques

Advanced Theory and Simulations, Volume 8, Issue 5, May 2025.
Ultra‐pure silicon single‐crystals can be grown by the Floating Zone (FZ) method. This study investigates intricate relationships between process stability measures and multiple growth parameters by applying data mining techniques on FZ simulations. Regression Trees identified multivariate relationships that help explaining complex interactions between

Hydrophobin‐Coated Echogenic Microbubbles for Molecular Targeting of Tumor Cells

Advanced Science, EarlyView.
Echogenic microbubbles based on hydrophobin and corresponding fusion protein (HFBI‐domZ) are developed as contrast agents for cancer diagnostics. Hydrophobin provides high stabilization of encapsulated perfluoro‐n‐butane, and fusion proteins allow further versatile functionalization with antibodies. In‐vitro experiments indicate that these microbubbles

Condensate Halos in Condensation Frosting

Advanced Science, Volume 12, Issue 14, April 10, 2025.
The freezing of supercooled water drops on cold solid surfaces is an interfacial phase‐change phenomenon accompanied by complex heat and mass transfer yet remains partly understood. By combining optical and thermal imaging techniques, the study scrutinizes the formation, growth, and fading of condensate halos consisting of massive small droplets around
