Ozone and alkyl nitrate formation from the Deepwater Horizon oil spill atmospheric emissions [PDF]

, 2012
Ozone (O3), alkyl nitrates (RONO2), and other photochemical products were formed in the atmosphere downwind from the Deepwater Horizon (DWH) oil spill by photochemical reactions of evaporating hydrocarbons with NOx (=NO+NO2) emissions from spill response

Chiral Nanohoops as an Efficient Spin Polarization System

Advanced Functional Materials, EarlyView.
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...

Inter- and intramolecular enantioselective carbolithiation reactions

Beilstein Journal of Organic Chemistry, 2013
In this review we summarize recent developments in inter- and intramolecular enantioselective carbolithiation reactions carried out in the presence of a chiral ligand for lithium, such as (−)-sparteine, to promote facial selection on a C=C bond.

Mechanically Stable and Tunable Photoactivated Peptide‐Based Hydrogels for Soft Tissue Adhesion

Advanced Functional Materials, EarlyView.
A collagen‐like peptide hydrogel platform is developed using supramolecular self‐assembly and light‐triggered crosslinking. It creates mechanically stable, tunable hydrogels with cytocompatibility and biodegradability, making them potential soft tissue adhesives.

Anomere Amide Ermöglichen Aminative Alken‐Aryl‐ und Alken‐Alken‐Kupplungen

Angewandte Chemie
AbstractTrotz der Bedeutung von Kreuzkupplungsreaktionen, bei denen C−N‐Bindungen gebildet werden, stellen aminative Kupplungsansätze, bei denen zwei Fragmente direkt am Heteroatom verknüpft werden, eine selten genutzte retrosynthetische Strategie für den molekularen Aufbau dar.
