Exploiting Device Deformability for Fluid and Particle Manipulation

Small, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Modeling and Simulation for Micromilling Mechanisms

Procedia Engineering, 2017
Abstract In order to study the micromilling mechanisms, FEM (finite element method) has been used to create models and to conduct simulations for micromilling process. The aluminum alloy material 7075-T6 is selected as the workpiece material for its advantages to make miniaturized components.

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

In‐Mold Wettability Patterning of Microfluidic Devices Without Back‐End Surface Modification

Chemistry–Methods, Volume 6, Issue 6, June 2026.
This study demonstrates in‐mold wettability patterning of microfluidic devices, eliminating the need for post‐fabrication surface modification to define hydrophilic and hydrophobic regions. The new approach enables efficient droplet seeding in hydrophilic‐in‐hydrophobic well arrays and selective wettability of microchannels in fluidic devices.

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

Advanced Materials Technologies, Volume 11, Issue 7, 6 April 2026.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Vibration Propagation Characteristics of Micro-Milling Tools

Machines, 2022
Micro-milling tools are usually used for the 3D precision processing of micro metal parts under ultra-high speed. However, due to the structural characteristics of small scale, variable cross-section, and weak stiffness, the vibration of micro-milling ...
