Aircraft emissions of nitrogen oxides (NOx= NO + NO2), aerosols, and aerosol precursors provide a non-negligible contribution to the climate impact of air traffic, and the uncertainty in their climate Effective Rad...

The chemical behavior of sulfur in the interstellar medium (ISM), particularly in the dense regions where stars form, is still far from being well understood. Questions such as which is the main sulfur reservoir in the I...

Cloud morphological transitions strongly influence radiative effects and the regional radiation budget. Marine cold-air outbreaks (MCAOs) over the northwestern Atlantic feature such transitions. Characterizing these tran...

The Pampeano aquifer formed by loess-like sediments provides water to cities and for agricultural uses in the Pampean plain, which is the most productive area in Argentina. Studies on the mechanisms through which this gr...

In marine environments, the increased drag force on vehicles impedes their speed underwater, leading to high energy consumption and reduced vehicle efficiency. Superhydrophobic coatings have gained remarkable attention r...

Mercury (Hg) is a contaminant of global concern, and an accurate understanding of its atmospheric fate is needed to assess its risks to humans and ecosystem health. Atmospheric oxidation of Hg is key to the deposition of...

The realization of higher coupling strengths between coupled resonant modes enables exploration of compelling phenomena in diverse fields of physics and chemistry. In this study, we focus on the modal coupling between lo...

This study presents the chemical and isotopic compositions of hydrothermal gases from fumaroles discharging around Copahue volcano (Argentina). Gas samples, including those from two fumaroles at the active summit crater,...

Copper sites in proteins are designed to perform either electron transfer or redox catalysis. Type 1 and CuA sites are electron transfer hubs bound to a rigid protein fold that prevents binding of exogenous ligands and s...

The rechargeable lithium air (oxygen) battery (Li-O2) has very high energy density comparable to fossil fuels (∽3,600 Wh/kg). However, the parasitic reactions of the O2- reduction products with solvent and electrolyte ...

Industrial Biotechnology and Applied Microbiology is an optional 128h-course for Chemistry and Biology students at the Faculty of Sciences, University of Buenos Aires, Argentina. This course is usually attended by 25 stu...

China's Clean Air Action (CAA) plan implemented since 2013 has significantly altered atmospheric composition, and yet its impact on the terrestrial carbon sink remains unclear. This study employed the Regional Earth Syst...

Los monoterpenos y otros compuestos orgánicos volátiles emitidos por la vegetación(emisiones biogénicas) juegan un papel significativo en la química troposférica porsu participación en la formación de oxidantes f...

The pecan nutshell [Carya illinoinensis (Wangenh) C. Koch] (PNS) is a source of bioactives with important beneficial properties for the human health. PNS represents between 40–50 % of total mass of the nut, resulting ...

The problem of incomplete data matrices is repeatedly found in large databases; posing a significant obstacle for an effective treatment of data. This paper examines a self-organizing-map (SOM) based method of data imput...

Cerium-based materials were intensively studied in last years because of their high oxygen storage capacity (OSC) associated to the reversible Ce4+ Ce3+ process and their properties closely related to the defect chemistr...

The aggregation of α-synuclein is associated with progression of Parkinson's disease. We have identified submicrometer supramolecular structures that mediate the early stages of the overall mechanism. The sequence of st...

We present herein an in-depth study on the activity of amidinoquinoxaline N-oxides 1 against Gram-positive and Gram-negative anaerobic bacteria. Based on 5-phenyl-2,3-dihydropyrimidoquinoxaline N-oxide 1a, the selected s...

Antimicrobial finishings protect users from pathogenic and odor-generating microorganisms, which are of medical and hygiene concerns. Controlled release is a useful approach to obtain antimicrobial finishings in several ...

We present a study of the microscopic dynamics of water trapped in reverse non-ionic micelles by means of a series of molecular dynamics simulations. The analysis of the effects of micellar confinement on spectroscopical...

Mitigating anthropogenic methane emissions is widely recognized as an effective strategy to reduce near-term climate warming. Here, we use satellite observations from MethaneSAT (2024–2025) to characterize methane emis...

The temperature sensitivity of fine particulate matter (PM2.5) critically influences air quality and human health under a warming climate, yet models struggle to accurately reproduce observed sensitivities. This study im...

Extreme indoor and outdoor conditions in patients’ places of stay (hot or cold air and changes in humidity) lead to weakening of the lipid barrier function and disproportionate epidermal microbiota which results in a l...

We are reporting two new mixed valent Co(ii)/Co(iii) polynuclear complexes, {Co II 6 Co III 3 } and {Co II Co III 4 }, bearing different amount of Co(ii) ions in their cores, through the employment of the multidentate tr...
