Precisely Timed On‐Demand Droplet Ejection and Collision in Free Space for Controlled Reaction Initiation

Small, EarlyView.
LiDIA is an on‐demand droplet‐in‐air platform that enables synchronized droplet collision, ultralow‐waste operation, and obstruction‐free sample delivery. By combining precise triggering with reliable free‐space dispensing, it provides a versatile route for rapid mixing and time‐resolved studies, with strong potential for applications in XFEL, cryo‐EM,

Covalent Organic Framework Electrolytes for Solid‐State Lithium Batteries: Designing Ion Highways for Next‐Generation Energy Storage

Small, EarlyView.
Covalent organic frameworks provide a structurally programmable platform for solid‐state lithium batteries. This review outlines a design framework linking structural descriptors to ion‐transport metrics. It examines mechanisms of confinement, channel architecture, and hybrid designs, addressing the reasons for the occasional failure of high intrinsic ...

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

Small, EarlyView.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Engineering Cobalt‐Based Thin Films for Fischer–Tropsch Synthesis

Small, EarlyView.
Cobalt thin films with tailored crystalline phases and oxidation states serve as well‐defined model Fischer–Tropsch catalysts. In situ synchrotron GIXRD reveals distinct reduction behaviour and phase evolution, while catalytic testing demonstrates phase‐dependent hydrocarbon selectivity and improved structural stability. These model thin‐film catalysts

Revealing Airflow–Particle Dynamics in Dry Powder Inhalers

Small, EarlyView.
An integrated framework combining device and formulation characterization, CFD–DEM simulations, and interpretable machine learning is established. This framework reveals how airflow and particle interactions govern powder dispersion across prevailing dry powder inhalers.

Regulating Copper Nuclearity in Metal–Organic Frameworks for the Hydrogenation of Carbon Dioxide

Small Methods, EarlyView.
CO2 hydrogenation on Cu‐metalated MOFs at gas–solid and liquid–solid interfaces depend strongly on the nuclearity of the Cu, which can be adjusted via the density of defects and the synthesis process. In both reaction regimes, methanol formation is favored on Cu clusters rather than on isolated Cu sites, highlighting the critical role of metal ...
