Microfluidic Capillary Arrays for Pixelated Control of Multimaterial Flows

open access: yesSmall, EarlyView.
A 3D‐printed pixellated capillary array maps up to thousands of fluid inputs into arbitrary multimaterial flow cross‐sections. Automated manifold design and laminar scaling are used to amplify printing resolution orders of magnitude, generating microscale fluidic control from printed elements, enabling designed microflows for potential use in ...

Steady‐State and Dynamic Behavior of Geometry‐Tunable Microfluidic Passive Flow Regulators

open access: yesSmall, EarlyView.
Passive microfluidic flow regulators exhibit geometry‐dependent dynamic behavior, where channel width governs the resistance–compliance interactions within the system. Narrow channels produce faster responses with higher bandwidth, while wider channels yield slower responses and stronger attenuation.

Spatial Activity Patterning and Topological Defect Transport in Acoustically Energized Active Liquid Crystals

open access: yesSmall, EarlyView.
Channel geometry is used to pattern activity in acoustically energized active liquid crystals, producing controlled, directional transport of topological defects. The mechanism is revealed by experiment and minimal modeling, offering a new design principle for programmable topological transport and active microfluidic architectures. ABSTRACT Patterning

Nitrogen‐Doped GeTeS Ovonic Threshold Switching Selector With Optimized Performance Trade‐Off for 1S–1R Phase‐Change Memory

open access: yesSmall, EarlyView.
This study introduced a Ge‐Te‐S co‐sputtering process to resolve the performance trade‐off between GeTe and GeS in OTS selector devices, and improved device durability through nitrogen doping. Furthermore, in a 1S‐1R structure incorporating phase‐change memory devices, it simultaneously achieved excellent thermal stability, durability, high‐speed ...

Shear‐Responsive Red Blood Cell Carriers for Targeted Drug Delivery to Constricted Arteries

open access: yesSmall, EarlyView.
Red blood cells are harnessed as mechanoresponsive carriers that exploit the elevated shear stress of stenotic arteries to transiently open membrane pores and release encapsulated therapeutics selectively at sites of arterial narrowing. By coupling vascular hemodynamics with RBC membrane mechanics, a hemodynamically activated platform for localized ...

Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

open access: yesSmall, EarlyView.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

Multi‐Scale Engineering of Photonic Meta‐Structures With Emergent Optical Resonances via Colloidal Crystal Engineering With DNA and Microwell Templates

open access: yesSmall, EarlyView.
This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.

Unraveling Pathway Complexity in Photoreversible Supramolecular Hydrogels: Real‐Time Visualization and Sub‐Micrometric Photopatterning

open access: yesSmall, EarlyView.
This research demonstrates real‐time visualization of supramolecular sol‐gel transitions using Fluorescence Lifetime Imaging Microscopy (FLIM). By leveraging 5D visualization, integrating 3D space, time, and polarity resolution, we achieved maskless sub‐micrometric photopatterning within the gel matrix.

Data‐driven elemental descriptors for rational design of high‐sensitivity extreme ultraviolet photoresists

open access: yesSmart Molecules, EarlyView.
Data‐driven descriptors indicate that elements such as I, Te, In, Sn, Sb, Cs and Bi have positive impact on EUV sensitivity in photoresists, whereas elements like C and H exhibit negative contributions. Abstract The rational design of high‐sensitivity photoresists for extreme ultraviolet (EUV) lithography is hindered by the lack of quantitative ...
