Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

Journal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

Quartz Clouds in the Dayside Atmosphere of the Quintessential Hot Jupiter HD 189733 b

The Astrophysical Journal Letters
Recent mid-infrared observations with JWST's Mid-Infrared Instrument Low Resolution Spectrometer (MIRI LRS) have resulted in the first direct detections of absorption features from silicate clouds in the transmission spectra of two transiting exoplanets,

Near-infrared spectroscopy of the atmosphere of Jupiter

Journal of Quantitative Spectroscopy and Radiative Transfer, 1984
Abstract The spectroscopic properties of the atmosphere of Jupiter are reviewed and the uses of spectroscopy for remote sensing of the Jovian composition, thermal structure and cloud properties are discussed. The limitations of earth-based and existing spacecraft spectroscopy and the prospects for the Near Infrared Mapping Spectrometer on the ...

Navigating the Net Zero Transition: Towards Improved Effectiveness of Corporate Decarbonization Strategies

Business Strategy and the Environment, EarlyView.
ABSTRACT With net zero CO2 emissions as the benchmark for mitigating the worst impacts of climate change by mid‐century, businesses are urged to deploy robust reduction measures. However, in light of increasing emissions globally, the effectiveness of current corporate decarbonization strategies remains unclear.

Jupiter’s Tropical Atmosphere: Shallow Weather, Deep Plumes, and Vortices

The Planetary Science Journal
Towering storms, swirling clouds, and vortices are the cloud top manifestation of complex weather systems shaping the atmosphere of Jupiter. We use observations from Juno’s MicroWave Radiometer (MWR), the Karl G.

Entropy‐Controlled Exsolution of Highly Dispersed Nickel‐Based Active Metals From Spinel Oxide via Optimizing Metal‐Support Interaction for Dry Reforming of Methane

Carbon Energy, EarlyView.
The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

The Canadian Journal of Chemical Engineering, EarlyView.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and

Two Classes of Hot Jupiter Atmospheres [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractWe highlight the potential importance of gaseous TiO and VO opacity on the highly irradiated close-in giant planets. The day-side atmospheres of these planets may naturally fall into two classes that are somewhat analogous to the M- and L-type dwarfs. Those that are warm enough to have appreciable opacity due to TiO and VO gases we term the “pM

Efficient Recycling of Spent LiCoO2 Cathodes Via Confined Pore‐Assisted Simplified Direct Carbothermic Reduction Without External Reducing Agents

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A simplified direct carbothermic reduction (SDCR) process is developed for efficient recycling of spent LiCoO2 cathodes. The SDCR method employs carbon conductive agents and organic binders embedded in the electrode as internal reducing agents, while the confined pores of calendered electrodes promote the retention of in situ generated reduction gases.

Diagnosing the Atmosphere of Jupiter's Volcanic Moon Io Using Energetic Neutral Atoms (ENAs)

Geophysical Research Letters
During a Juno spacecraft encounter with Jupiter's volcanic moon Io (30 December 2023), the Jupiter Energetic Particle Detector Instrument (JEDI) observed Energetic Neutral Atoms (ENAs) of >150 keV oxygen and sulfur (O + S) coming from Io's mostly ...
