Schiff based derived homogeneous catalysts for ring‐opening terpolymerization

open access: yesPolymer International, EarlyView.
One‐pot synthesis of degradable terpolymers from l‐lactide, propylene oxide and CO₂ using diverse catalysts is described, revealing structure–property relationships for tailored applications in sustainable materials. Abstract In this study, we synthesized and evaluated a series of Schiff base cobalt catalysts for the terpolymerization of propylene ...

IRAS 16293-2422: Evidence for Infall onto a Counter-Rotating Protostellar Accretion Disk [PDF]

open access: yes, 2005
We report high spatial resolution VLA observations of the low-mass star-forming region IRAS 16293-2422 using four molecular probes: ethyl cyanide (CH$_3$CH$_2$CN), methyl formate (CH$_3$OCHO), formic acid (HCOOH), and the ground vibrational state of ...

Integrating DynamiCROP model and risk assessment for pesticide residues in spinach: Implications for food safety

open access: yesPest Management Science, EarlyView.
This study adapted and validated the dynamiCROP model for spinach, a leafy vegetable not previously included in its standard framework. The findings confirm that model‐predicted pesticide concentrations, when integrated into hazard quotient (HQ) calculations, can effectively support dietary risk assessment.

Theoretical performance optimization of enzymatic electrochemical CO2 reduction to formate: Voltage, concentration, temperature, pressure, and flow rate

open access: yesJournal of CO2 Utilization
Formic acid (FA) is a notable fuel product due to its atom economy, low activation energy, and applications in flow cells and hydrogen storage. While metal catalysts are typically used, selectivity remains a challenge.

Searching for Trans Ethyl Methyl Ether in Orion KL

open access: yes, 2015
We report on the tentative detection of $trans$ Ethyl Methyl Ether (tEME), $t-CH_3CH_2OCH_3$, through the identification of a large number of rotational lines from each one of the spin states of the molecule towards Orion KL. We also search for $gauche$-$
