Evaluation of the Efficiency of a Biobased Reactive Plasticizer on the Morphology and Properties of Sustainable Flexible Films Based on Poly(Lactic Acid) (PLA) Produced by Blown Film Extrusion

open access: yesJournal of Applied Polymer Science, EarlyView.
A comparative investigation of two epoxy additives derived from cardanol (NC513 and NC514s) for production of films based on poly (lactic acid) (PLA), acetyl tributyl citrate (ATBC), and poly (butylene adipate‐co‐terephthalate) (PBAT) clarified their distinct roles, with NC513 mainly acting as a plasticizer, reducing viscosity and enhancing ductility ...

Quantum Heat Current in Terahertz‐Driven Phonon Systems

open access: yesAdvanced Physics Research, EarlyView.
We develop a quantum mechanical description of ultrafast thermodynamics on the example of a laser‐excited phonon mode. We show that the resulting quantum heat current exhibits non‐Markovian dynamics, which can be controlled by the pulse length. ABSTRACT The advent of high‐intensity ultrafast laser pulses has opened new opportunities for controlling and

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

open access: yesBMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

Computed tomography detected pyelovenous backflow associated with complete ureteral obstruction

open access: yesIJU Case Reports, 2019
Introduction Pyelovenous backflow is a rare condition resulting from an increase in pressure in the renal pelvis due to urinary obstruction. Case presentation A 49‐year‐old woman developed high‐grade fever and right‐sided hydronephrosis after undergoing ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Boosting Electron‐Hole Charge Separation in CO2 Photoreduction through Fluoroporphyrin‐Linked Nickel(II)‐Acetylide Frameworks

open access: yesCarbon Energy, EarlyView.
A NiII‐acetylide framework, H2TFPP‐Ni‐AF, demonstrates outstanding photocatalytic CO2 reduction performance: 13.16 mmol h−1 g−1 of CO with 97.9% selectivity. Synergistic interactions, including d‐p orbital hybridization within NiII‐bis(acetylide) moieties ( − C ≡ C−NiII(PBu3)2 − C ≡ C − ) and the efficient charge transport afforded by π‐conjugated ...
