Cutoff and Emergence of Dart Leaders in an Unbranched Positive Leader Simulation

open access: yesGeophysical Research Letters
Channel cutoff is the process by which an active lightning channel cools down, goes dark, and loses its ability to effectively conduct electricity. Current cutoff precedes several lightning phenomena, notably dart leaders and return strokes, but the ...

Ram-wake effects on plasma current collection of the PIX 2 Langmuir probe [PDF]

open access: yes, 1985
The Plasma Interaction Experiment 2 (PIX 2) Langmuir probe readings of the same polar magnetospheric regions taken on consecutive orbits showed occasional apparent densities as much as 10 times lower than the average, although each pass clearly showed ...

Robust autoresonant excitation in the plasma beat-wave accelerator: a theoretical study

open access: yes, 2004
A modified version of the Plasma Beat-Wave Accelerator scheme is introduced and analyzed, which is based on autoresonant phase-locking of the nonlinear Langmuir wave to the slowly chirped beat frequency of the driving lasers via adiabatic passage through

Three‐Dimensional Hierarchical Nanowire‐Networks with Deep‐Focus Tolerance and Adhesion Robustness for Harsh‐Environment SERS Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications

open access: yesAdvanced Functional Materials, EarlyView.
Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Adsorption of Bovine Serum Albumin onto Hydroxylapatite: Theoretical Modeling and Measurements [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2010
Adsorption of Bovine Serum Albumin (BSA) onto calcium Hydroxyl Apatite (HA), Ca10PO4(OH)2, has been studied by Ultra Violet (UV) spectroscopy. The adsorption isotherms of BSA onto the HA surface at 291.7 K and 303.2 K were satisfactorily presented by ...

Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.
