Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

open access: yesAdvanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

Morphology-Tailored Dynamic State Transition in Active-Passive Colloidal Assemblies

open access: yesResearch
Mixtures of active self-propelled and passive colloidal particles promise rich assembly and dynamic states that are beyond reach via equilibrium routes. Yet, controllable transition between different dynamic states remains rare.

Block Copolymers: Emerging Building Blocks for Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
This review addresses how block copolymer (BCP) physics and rheology have led to the widespread use of BCPs in advanced additive manufacturing techniques, with particular emphasis on the untapped potential of these nanostructured materials toward achieving multi‐scale architected materials with unique, programmable material properties.

Colloidal active matter

open access: yesEurophysics News
In the last two decades, significant research progress has been made in artificially equipping colloidal particles with their own drive (“motor”). They are then called active particles. In this case, a single active colloid typically moves much faster and more dynamically than a passive one, which follows purely diffusive Brownian motion.

Real‐Time, Label‐Free Monitoring of Cell Behavior on a Bioelectronic Scaffold

open access: yesAdvanced Functional Materials, EarlyView.
A bioelectronic nanofibrous scaffold is introduced that supports cell growth while enabling real‐time, label‐free monitoring of cellular behavior through impedance measurements. The system correlates electrical signals with cell viability and surface coverage, offering an integrated platform for studying dynamic biological processes and advancing next ...

Active Colloidal Gels

open access: yes, 2022
On their way towards equilibrium, but kinetically arrested, colloidal gels is a peculiar state of matter halfway between liquids and solids. Systems of active particles that convert external energy into mechanical work have been the focus of intense research in the past 25 years, as they exhibit a number of phases of matter, which are out of reach for ...

Traveling Strings of Active Dipolar Colloids [PDF]

open access: yesPhysical Review Letters
We study an intriguing new type of self-assembled active colloidal polymer system in 3D. It is obtained from a suspension of Janus particles in an electric field that induces parallel dipoles in the particles as well as self-propulsion in the plane perpendicular to the field.

Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

open access: yesAdvanced Functional Materials, EarlyView.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Principle of intravenous fluid therapy in the neurocritically ill patients [PDF]

open access: yesJournal of Neurocritical Care
Intravenous fluid therapy is a fundamental treatment in intensive care units (ICUs). Although most clinical trials have focused on patients requiring active resuscitation of the intravascular volume, such as those experiencing shock or sepsis ...
