Kinetic Study on the Reaction of Phenylperoxy Radicals With Nitric Oxide

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Cavity ring‐down spectroscopy (CRDS) and quantum cascade laser absorption spectroscopy (QCLAS), in conjunction with pulsed laser photolysis, were employed to investigate the reaction between phenylperoxy radicals (C6H5O2) and nitric oxide (NO) at a temperature of 296 ± 4 K. The experiment was carried out under N2 as bath gas.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Sensitivities of Large Eddy Simulations of Aerosol Plume Transport and Cloud Response

open access: yesJournal of Advances in Modeling Earth Systems
Cloud responses to surface‐based sources of aerosol perturbation partially depend on how turbulent transport of the aerosol to cloud base affects the spatial and temporal distribution of aerosol.

Glucocorticoids Impair the Airway Epithelial Barrier via Autophagy‐Associated Apoptosis in Asthma: A Preliminary Study Both In Vitro and In Vivo

open access: yesPediatric Discovery, EarlyView.
Mechanism underlying the negative effects of glucocorticoids on the airway epithelial barrier. Glucocorticoids upregulate autophagy factors and downregulate anti‐autophagy factors. Enhanced autophagy promotes excessive apoptosis and epithelial detachment, impairing airway barrier function.

Human Umbilical Cord Mesenchymal Stem Cell‐Derived Microvesicles Alleviate Bronchopulmonary Dysplasia in Preterm Rats by Inhibiting Neutrophil Extracellular Trap Formation

open access: yesPediatric Discovery, EarlyView.
Excessive neutrophil extracellular trap (NET) extrusion (NETosis) links prenatal inflammation to bronchopulmonary dysplasia (BPD) pathogenesis. Treatment with human umbilical cord mesenchymal stem cell‐derived microvesicles suppresses NET formation, reduces lung injury, and promotes alveolarization in a preterm rat model, offering a promising cell‐free

Using optimization tools to explore stratospheric aerosol injection strategies

open access: yesEarth System Dynamics
Abstract. Stratospheric aerosol injection (SAI), as a possible supplement to emission reduction, has the potential to reduce some of the impacts associated with climate change. However, the outcomes will depend on how it is deployed: not just how much but also the latitudes of injection and the distribution of injection rates across those latitudes ...

Scaling turbulence drives the general circulation

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Change in Wind Renewable Energy Potential Under Stratospheric Aerosol Injections

open access: yesEarth's Future
Abstract Wind renewable energy (WRE) is an essential component of the global sustainable energy portfolio. Recently, there has been increasing discussion on the potential supplementation of this conventional mitigation portfolio with Solar Radiation Modification (SRM). However, the impact of SRM on conventional mitigation measures has
