Photoinduced Electron Transfer (PET) as Key to Accelerate the Cycloreversion Reaction of Arylquadricyclanes

open access: yesChemistry – A European Journal, EarlyView.
It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

open access: yesChemistry – A European Journal, EarlyView.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Pd‐Catalyzed C─C Bond Borylation of Biphenylenes Leading to Tri‐Ortho‐Substituted Biaryls

open access: yesChemistry – A European Journal, EarlyView.
Palladium‐catalyzed ring‐opening C─C borylation of 1‐substituted biphenylenes yields a range of o,o,o′‐trisubstituted biaryls with two ortho‐boryl groups via selective cleavage of the least hindered C─C bond. The resulting diborylated products are readily amenable to sequential, site‐selective postfunctionalization.

Traceability as Part of Competitive Strategy in the Fruit Supply Chain [PDF]

open access: yes
This paper discusses traceability as part of information management in fruit supply chains of Emilia-Romagna, Italy. A review of the rules in use for traceability distinguishes between a proper traceability and a traceability plus (T+), embedded of many ...

Carbon monoxide adsorption on NaY zeolite and impregnated with 5% niobium: Characteristics and fixed‐bed study

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Schematic of the CO adsorption process in a fixed‐bed column containing pure NaY zeolite and Nb‐modified NaY (NaY–5%Nb). On the left, breakthrough curves and temperature profiles highlight the dynamic performance and thermal effects during CO adsorption.

Building a Robust Investigator‐Initiated Platform: The I‐CARE Experience

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Investigator‐initiated studies that include information collected by patients are rising, but limited data is available on patient and investigator experience in this setting. The I‐CARE cohort included patients with inflammatory bowel disease (IBD) monthly collecting clinical information in 15 countries for up to 6 years.
