Plasma–Kinetic Coupling and Redox Mechanisms in the Degradation of Acid Red 51 by Atmospheric Corona Discharge

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the degradation of the xanthene dye Acid Red 51 (ARE‐51) using atmospheric‐pressure corona discharge plasma, integrating electrical characterization, optical emission spectroscopy (OES), kinetic modeling, and physicochemical analysis to establish a unified plasma–liquid interaction framework. A degradation efficiency of

Design Considerations for Polymer–Deep Eutectic Solvent Hybrid Systems for Transdermal Drug Delivery

open access: yesJournal of Applied Polymer Science, EarlyView.
Deep eutectic solvents (DESs) act as tunable, green excipients that modulate polymer structure–property relationships to enhance drug solubility, skin permeation, stability, and controlled release. Through hydrogen‐bond interactions, DES–polymer hybrid systems enable improved transdermal performance, offering a rational, design‐driven platform for ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Dental crown morphological variation and heterodonty in carcharhiniform sharks

open access: yesThe Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

O dirigismo laico: D. Pedro II e o projeto imperial

open access: yesAtas do ..., 2006
Este estudo traça um breve esboço sobre a maneira pela qual a historiografia trata o mecenato artístico de D. Pedro II, sua relação com os projetos construtores da incipiente nação e a imagem criada do próprio monarca. Considera ainda a ruptura do academismo romântico face aos padrões neoclássicos nas artes plásticas.

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 ...

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).
