Biocompatible Ink Optimization Enables Functional Volumetric Bioprinting With Xolography

Advanced Materials, EarlyView.
Xolography's reliance on weak‐base co‐initiators introduces unique biochemical constraints. By dissecting the effects of extracellular pH, osmolality, and lysosomotropic stress, this study defines the biochemical design space that enables fully biocompatible, cell‐laden volumetric printing. Abstract Xolography is a novel linear volumetric manufacturing

High Resolution ALMA Data of the Fomalhaut Debris Disk Confirms Apsidal Width Variation

The Astrophysical Journal Letters
We present long-baseline observations of the Fomalhaut outer debris disk at 223 GHz (1.3 mm) from Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 5, which we use along with archival short-baseline observations to produce a 0 $\mathop{.}\limits{^

Straightforward Preparation of Polyurethane‐Based Biomaterials with Dual Antibacterial and Anti‐Adhesive Properties for Long‐Lasting Catheter Applications

Advanced Materials Interfaces, EarlyView.
This study presents the elaboration of antibacterial, antiadhesive, and antibiofilm polyurethane by a straightforward process based on the co‐extrusion of 2 wt.% of both antibacterial and antiadhesive copolymer. The material proves to be active even after pre‐exposition to biological media and prevents E. coli biofilm formation without toxicity.

Runaway accretion of metals from compact debris disks onto white dwarfs

, 2011
It was recently proposed that metal-rich white dwarfs (WDs) accrete their metals from compact debris disks found to exist around more than a dozen of them.

Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

Advanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.

Novel Manufacturing of Cellulose‐Based Membranes for Energy Storage Devices: Toward a PFAS Free Future

Advanced Sustainable Systems, EarlyView.
This work presents a novel, scalable method for manufacturing PFAS‐free cellulose‐based membranes for energy storage devices. By coating kraft paper with cellulose nanofibrils and optimizing barrier and ionic conductivity properties, membranes are achieved that prevent redox molecule crossover while maintaining performance.
