Local Evolution of a Prenoon Drainage Plume

Geophysical Research Letters
Plasmaspheric drainage plumes are typically observed in the postnoon sector during geomagnetic storms, but their local evolution in the prenoon sector remains poorly understood.

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Intersections involving waves and monopoles in eleven dimensions

, 1997
We consider intersections in eleven dimensions involving Kaluza-Klein monopoles and Brinkmann waves. Besides these purely gravitational configurations we also construct solutions to the equations of motion that involve additional M2- and M5-branes. The maximal number of independent objects in these intersections is nine, and such maximal configurations,

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

Advanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

''My will has chosen life!'': Revisiting The Piano (1993) Through Third-Wave Feminism

Art and Interpretation
The present article offers a theoretically grounded third-wave feminist reading of Jane Campion’s The Piano (1993), arguing that the film anticipates and articulates key principles associated with third-wave feminism, particularly autonomy, embodied ...

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

Advanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

A Combined Image Theory-Scattering Matrix Method for PEC Dihedral Geometries

IEEE Open Journal of Antennas and Propagation
We present a method for analyzing electromagnetic wave scattering from a set of objects located within a dihedral corner. The study focuses on the 2-D case and considers scatterers modeled as dielectric and/or perfectly conducting cylinders with ...

High‐Performance Piezoelectric Nanogenerators Based on Wurtzite BeO Nanowire Arrays

Advanced Materials Technologies, EarlyView.
This study demonstrates high‐performance piezoelectric nanogenerators based on 1D BeO nanowire arrays. The BeO nanowires exhibit a high piezoelectric coefficient (∼15.8 pm V−1) and deliver an output voltage of ∼26.1 V and power density of ∼0.32 µW cm−2.

Stability and dispersion relations of three-dimensional solitary waves in trapped Bose–Einstein condensates

New Journal of Physics, 2015
We analyse the dynamical properties of three-dimensional solitary waves in cylindrically trapped Bose–Einstein condensates. Families of solitary waves bifurcate from the planar dark soliton and include the solitonic vortex, the vortex ring and more ...
