Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds

The Chemical Record, EarlyView.
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

X-Shooter spectroscopy of young stellar objects: V - Slow winds in T Tauri stars [PDF]

, 2014
Disks around T Tauri stars are known to lose mass, as best shown by the profiles of forbidden emission lines of low ionization species. At least two separate kinematic components have been identified, one characterised by velocity shifts of tens to ...

Dynamic Capabilities for Circular Economy Innovations towards Net Zero: Acqua & Sole Case Study

British Journal of Management, EarlyView.
Abstract Circular economy innovations can support firms’ transition towards the ‘net‐zero target’, one of the key objectives that firms ought to pursue to face climate change. Dynamic capabilities are deemed pivotal to enhance circular economy innovations; however, little is known about which ones – and how – can contribute to reaching such objectives.

Detection of an inner gaseous component in a Herbig Be star accretion disk: Near- and mid-infrared spectro-interferometry and radiative transfer modeling of MWC 147

, 2007
We study the geometry and the physical conditions in the inner (AU-scale) circumstellar region around the young Herbig Be star MWC 147 using long-baseline spectro-interferometry in the near-infrared (NIR K-band, VLTI/AMBER observations and PTI archive ...

Computational fluid dynamic models as tools to predict aerosol distribution in tracheobronchial airways

Scientific Reports, 2021
Aerosol and pollutants, in form of particulates 5–8 μm in main size face every day our respiratory system as natural suspension in air or forced to be inhaled as a coadjutant in a medical therapy for respiratory diseases.

Microwave‐Assisted Recycling of Lithium‐Ion Batteries: Linking Process Optimization to Volatile Organic Compounds and Fluorinated Gases Emission Mitigation

Battery Energy, Volume 5, Issue 2, March 2026.
Microwave‐assisted recycling of black mass from spent lithium‐ion batteries was optimized through a Design of Experiments approach, linking heating parameters to lithium recovery efficiency and volatile emissions. Combining GC–MS and multinuclear NMR analyses, the study identifies key conditions minimizing hazardous fluorinated and organic gas ...

Revealing the sub-AU asymmetries of the inner dust rim in the disk around the Herbig Ae star R CrA

, 2009
Models predict that in the innermost AU of the disk around Herbig Ae/Be star, the dust disk forms a "puffed-up" inner rim, which should result in a strongly asymmetric brightness distribution for disks seen under intermediate inclination.
