Diagnosis of Portal Hypertension: Advancing Towards Non‐Invasive Solutions

Portal Hypertension &Cirrhosis, EarlyView.
This review systematically summarizes a full spectrum of non‐invasive diagnostic approaches for portal hypertension (PH), including imaging modalities, elastography, serum biomarkers, composite scoring systems and endoscopic ultrasound‐guided portal pressure gradient (EUS‐PPG), and analyzes their performance across different liver disease etiologies ...

Fragmentation Across Scales, Geography, and Climate Challenges in European Urban Climate Change Adaptation and Mitigation Research: A Bibliometric and Systematic Review

Sustainable Development, EarlyView.
ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Microfluidic Capillary Arrays for Pixelated Control of Multimaterial Flows

Small, 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 ...

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.

Tactic Behaviors in Asymmetric Pacman Particles

Small, EarlyView.
The swimming behavior of TiO2 Pacman particles exhibits different modes depending on the fuel and illumination conditions. However, the behavior of these intrinsically asymmetric particles is still not well understood, and here we present a first approach to modeling their dynamics. Furthermore, we investigate their fundamental responses to some of the

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

Small 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.

Programmable Porosity in Polymers via Microfluidic Templating and 3D Printing

Small Methods, EarlyView.
Fluid templating is a powerful way to produce porous polymers. Microfluidic technologies enable fine control over the dimension and packing of bubbles and droplets. Combined with additive manufacturing, microfluidic templating enables the creation of polymeric functionally graded porous materials in which both porosity and three‐dimensional geometry ...
