Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

Rare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Transforming Fragile Hydrogel Chips Into Standardized Cartridges via Contact Line Pinning for Robust Microfluidics

Small, EarlyView.
Hydrogel‐based microfluidic chips revolutionize drug delivery, tissue engineering, and biosensing, yet face challenges due to fragility and connection difficulty. This study introduces a novel cartridge design that enhances usability through a hydrogel–plastic hybrid design and a contactless connection method.

Ultrathin Freestanding MoSiN Nanocomposite Membranes as Efficient High‐Temperature Mid‐Infrared Thermal Emitters

Small, EarlyView.
Ultrathin freestanding MoSiN nanocomposite membranes are developed as stable and efficient mid‐infrared emitters for gas sensing under extreme thermal conditions. A 12 nm‐thick membrane combines intermetallic phases for enhanced IR absorption with a dielectric phase for mechanical stability.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

Small Structures, EarlyView.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Simultaneous Formation of Arsenic Nitride Chalcogenides As3NS3 and As3NSe3 and Arsenic–Chalcogen Zintl Anions by Ammonothermal Reactions

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Mn, As, and S or Se react in liquid NH3 to the Zintl ions (As4S6)2– and (As2Se6)2–. Simultaneously, the arsenic nitride chalcogenides As3NS3 and As3NSe3 are formed. Their isotypic structures contain planar trigonal NAs3 groups connected via chalcogen bridges to 1D‐strands forming channels that can host solvent molecules.
