Isolation Defines Identity: Functional Consequences of Extracellular Vesicle Purification Strategies

open access: yesAdvanced Healthcare Materials, EarlyView.
Four extracellular vesicle purification strategies are compared using ovarian‐cancer ascites and ES‐2 cell supernatants. A novel workflow links purification to function by combining particle‐normalized proteomics with matched cell‐free and cell‐based assays.

Coastal cryogenic processes and cabonate balance of the coastal waters of eastern Arctic seas in the light of a changing climate [PDF]

open access: yes, 2003
An observed increase in alkalinity of the East Siberian Sea during the last quarter of the XX century is the result of CO2 absorption from the atmosphere, a more intense transport of organic substances into the water due to more active erosion of ice ...

The Space Within: How Architected Voids Promote Tissue Formation

open access: yesAdvanced Materials, EarlyView.
This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating

Exploring the role of PdO and oxygen vacancies of Pd/CeO2 in bicarbonate hydrogenation

open access: yesJournal of CO2 Utilization
The hydrogenation of bicarbonates in aqueous solutions using a Pd-based catalyst is an effective method for the production of formate. Herein, we synthesized finely dispersed Pd/CeO2 catalysts via a two-step calcination method and evaluated their ...

A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening

open access: yesAdvanced Materials, EarlyView.
A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.
