Disorder‐Driven Fast Na+ Transport: From Crystalline to Amorphous Networks in the Mixed‐Anion NaTaOxCl6−2x Oxychlorides

open access: yesAdvanced Energy Materials, EarlyView.
Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

Pancake Lenses through Curved Lamination for Compact Virtual Reality

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents an ultrathin VR optical system based on a 1.35 in. microdisplay, leveraging curved lamination technology. Compared to mainstream solutions, the proposed design demonstrates superior compactness (volume compression by 12%) and enhanced optical performance.

Safety and Effectiveness of Sutimlimab in Cold Agglutinin Disease: A Real‐World International Experience

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Sutimlimab is a monoclonal antibody against complement fraction C1s approved for the treatment of hemolytic anemia due to cold agglutinin disease (CAD). Here, we analyzed and report the largest international CAD cohort of sutimlimab‐treated patients ever reported to highlight its safety and effectiveness in the real‐world setting. We accrued a

Mimikry eines Lichtsammelkomplexes zur Beschleunigung der Photooxidation in asymmetrischen Lipidmembran‐Nanoreaktoren

open access: yesAngewandte Chemie, EarlyView.
Biomimetische Liposomen‐Nanoreaktoren, die natürliche Lichtsammelkomplexe nachahmen, ermöglichen eine effiziente Photooxidation von NADH. Membrangebundenes Fluorescein überträgt Energie über FRET an membrangebundenes Eosin Y und oxidiert so NADH.

Enhanced Rheological and Filtration Performance of Drilling Fluids Using Fe3O4/Saponin/Cu(II) Nanocomposites: Synthesis, Characterization, and Application

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Drilling fluids used in high‐performance well operations often struggle to maintain rheological stability, colloidal dispersion, and filtration control under harsh downhole conditions. This study engineered a multifunctional Fe3O4@Saponin/Cu(II) nanocomposite to address these challenges.

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...
