The orbital motion, absolute mass, and high-altitude winds of exoplanet HD209458b

open access: yes, 2010
For extrasolar planets discovered using the radial velocity method, the spectral characterization of the host star leads to a mass-estimate of the star and subsequently of the orbiting planet. In contrast, if also the orbital velocity of the planet would

Homocysteine Exacerbates Pulmonary Fibrosis via Orchestrating Syntaxin 17 Homocysteinylation of Alveolar Type II Cells

open access: yesAdvanced Science, EarlyView.
The study identifies elevated homocysteine (Hcy) levels in idiopathic pulmonary fibrosis patients' samples, with alveolar type 2 cells as the primary site of Hcy metabolism. Methionine synthase reductase downregulation in these cells exacerbates fibrosis, while folate administration reduces Hcy levels and alleviates fibrosis.

Structural Effects of Carbon Monoxide Coordination to Carbon Centers. π and σ Bindings in Aliphatic Acyl \u3cem\u3eversus\u3c/em\u3e Aromatic Aroyl Cations [PDF]

open access: yes, 2004
The binding of carbon monoxide to carbon centers has been examined with two series of aromatic and aliphatic oxocarbonium ions that are successfully isolated as crystalline and highly reactive (hygroscopic) aroylium and acylium salts with poorly ...

Liquid Metal Printed Zinc Tin Composite Oxide Nanosheets: A Platform for Multifunctional Sensing at Room Temperature

open access: yesAdvanced Science, EarlyView.
This work introduces a vacuum‐free liquid metal printing approach to create ultrathin zinc–tin composite oxide nanosheets. The material shows strong UV light responsiveness and high sensitivity to ammonia gas at room temperature, highlighting the potential of mixed metal oxides for advanced environmental sensors and optoelectronic device technologies ...

ST Elevation Myocardial Infarction Due to Carbon Monoxide Poisoning

open access: yesEurasian Journal of Medicine, 2011
Carbon monoxide is formed as a result of combustion of any carbon compound and can lead to hypoxia in many organs including the brain and the heart. Carbon monoxide poisoning in the United States is the leading cause of the fatal poisonings.

Carbon monoxide pollution experiment [PDF]

open access: yes
The experiment is designed to obtain data for the investigation of mechanisms by which CO is removed from the earth's atmosphere. The approach uses an orbiting platform to remotely map global CO concentrations and determine vertical CO profiles using a ...

Upcycling Spent Graphite Anodes into Bifunctional Photothermal Catalysts for Efficient PET Chemical Recycling

open access: yesAdvanced Science, EarlyView.
Waste graphite anodes from spent lithium‐ion batteries serve as a sustainable lithium source for synthesizing lithium ethylene glycolate. This reactive species efficiently catalyzes PET depolymerization under mild conditions, achieving rapid and selective monomer recovery.
