Giant‐Domain Perovskite Films via Reduced‐Temperature Meniscus‐Guided Coating: Fluid‐Dynamic Control of Supersaturation

open access: yesSolar RRL, Volume 10, Issue 6, 29 March 2026.
Fluid‐dynamic control of supersaturation is unlocked to resolve the trade‐off between film continuity and crystal growth in perovskite bar‐coating. By utilizing a thermally driven circulation loop that suppresses excessive evaporation, we realize giant‐domain films at reduced temperatures.

Unsteady aerodynamic calculations of flappping wing motion [PDF]

open access: yes, 2007
Bu tez çırpan kanat hareketinin havada asılı kalma modunu inceleyerek gelecektekimikro hava araçları uygulamalarına ısık olmayı amaçlamıstır. Bu çalısmada, düsükReynolds sayısında kanat kesitinin sekli, kalınlığı, kambur dağılımı gibi geometricparametrelerin ve bunların yanında çırpan kanat hareketinin aerodinamik kuvvetkatsayılarının ve girdap olusum ...

Finding Local Parallel Electric Fields in Magnetotail Reconnection Using a Two‐Spacecraft Method

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the use of a novel two‐spacecraft Liouville‐mapping method using data from the Magnetospheric Multiscale mission to determine local magnetic‐field‐aligned (parallel) electric fields in the Earth's magnetotail. The method detects the presence of local acceleration potentials by mapping phase‐space density between electron ...

Decadal Shifts in Groundwater Age Detected by Environmental Tracers Across California, USA

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Groundwater age offers important insight into recharge, storage, and contamination risk. Although models predict age changes can be driven by pumping and climate variability, direct observational evidence remains limited. Here, we analyzed paired environmental tracer suites (tritium, carbon‐14, and tritiogenic helium‐3) collected a decade ...
