Bacterial‐Based Molecular Communication: Simulation of a Fixed and Receding Receiver Scenarios in Varied Viscosities and Environmental Conditions

open access: yesAdvanced Theory and Simulations, EarlyView.
This study presents a robust 3D simulation for BBMC, focusing on both fixed and receding receiver scenarios across various conditions. Key parameters such as D, Q, u, and d are tested at different values to assess the performance and reliability of BBMC in applications like drug delivery, addressing critical challenges in nanoscale communication with ...

Comprehensive Characterization of Bihormonal Cells and Endocrine Cell Lineages in Mammalian Pancreatic Islets

open access: yesAdvanced Science, EarlyView.
This study integrates dual‐reporter genetics, imaging flow cytometry, and single‐cell sequencing to characterize rare bihormonal cells in mouse and human pancreatic islets. Gcg⁺Ins⁺ cells resemble α‐cells rather than transitional states. Cross‐species gene network analysis refines islet cell taxonomy and reveals human‐specific δ‐cell subtypes ...

Microporous Polymer Membranes: Molecular Stents Enhanced Solvent‐Accessibility for Organic Solvent Transport

open access: yesAdvanced Science, EarlyView.
A novel microporous polyimide (PI‐TB‐NDI) is designed for enhanced organic solvent nanofiltration. By incorporating o‐methyl groups into the Tröger's base (TB) unit to create molecular stents, the polymer's intrinsic free volume is effectively increased without the need for post‐treatment.

Microphysiological Uremia Model Reveals Biophysical Potentiators of Vascular Dysfunction

open access: yesAdvanced Science, EarlyView.
A microfluidic platform of engineered blood vessels is developed to study the role of mechanical forces in immune cell adhesion and extravasation in uremic microenvironments. Elevated pressure increases monocyte activity, with ICAM‐1 as a key driver. Matrix density influences monocyte phenotypes, but the uremic environment consistently promoted a pro ...

Template‐Free Fabrication of Single Atom Fe‐Based Cathodes Unlock High‐Performing Anion‐Exchange Membrane Fuel Cells

open access: yesAdvanced Science, EarlyView.
A high‐performance single‐atom critical‐raw‐material (CRM)‐free Fe‐based catalyst is designed using a template‐free manufacturing approach. This single‐atom catalyst (SAC) is incorporated into operando anion‐exchange membrane fuel cells using O2 and CO2‐free air displaying excellent performance.
