Role of Sidewall Conditions in the External Quantum Efficiency of InGaN‐Based Micro‐LEDs

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 6, June 2025.
The sidewall condition is an important factor determining external quantum efficiency (EQE) of InGaN‐based micro light‐emitting diodes (µLEDs). This study investigates the optimal thickness of the passivation layer and time of chemical treatment that are required to ensure a high EQE and reliability in LEDs since they strongly influence on the state of

Do guard cells have single or multiple defense mechanisms in response to flg22?

open access: yesPhysiologia Plantarum, Volume 177, Issue 3, May/June 2025.
Abstract Bacterial flagellin (flg22) induces rapid and permanent stomatal closure. However, its local and systemic as well as tissue‐ and cell‐specific effects are less understood. Our results show that flg22 induced local and systemic stomatal closure in intact tomato plants, which was regulated by reactive oxygen‐ and nitrogen species, and also ...

A novel metric for coronal MHD models [PDF]

open access: yes, 2009
[1] In the interest of quantitatively assessing the capabilities of coronal MHD models, we have developed a metric that compares the structures of the white light corona observed with SOHO LASCO C2 to model predictions.

Effects of urea fertilizer and nettle extract on the biochemical and morphological characteristics of ornamental peppers (Capsicum frutescens L.) under deficit irrigation conditions

open access: yesIrrigation and Drainage, Volume 74, Issue 2, Page 600-614, April 2025.
Abstract The aim of this study was to determine the effects of nettle extract, urea fertilizer and deficit irrigation on the biochemical and morphological characteristics of ornamental peppers. The study consisted of two irrigation (I) treatments (100% irrigation (I100) and 50% irrigation (I50)) and four fertilizer treatment groups (urea fertilizer: U;

Widespread Diagenesis at Unconformities in Gale Crater as Inferred From the Curiosity Rover and From Orbit

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract NASA's Curiosity rover has found widespread evidence of alteration in sedimentary rocks in Gale crater, Mars driven by interactions with fluids both before and after lithification (early and late diagenesis). Most notably, Curiosity observed distinctive color, chemical, and mineralogical changes interpreted as evidence of diagenesis at the ...
