Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment.

open access: yesPhysical Review Letters
On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of ...

Oxidative Dehydrogenation of N‐Heteroaromatic Alkyl Alcohols and Amines Facilitated by Dearomative Tautomerization

open access: yesChemistry – A European Journal, Accepted Article.
The oxidation of alcohols, amines, and halides is a fundamental transformation in organic chemistry with significant applications in the synthesis of fine chemicals, pharmaceuticals, and natural products. Here we show that a broad variety of N‐heteroarenes bearing hydroxymethyl, aminomethyl, or halomethyl groups are oxidatively dehydrogenated to their ...

N,N‐Bis(trifluoromethyl)aminoacetonitrile: A Versatile Building Block for the Introduction of the Bis(trifluoromethyl)amino Group

open access: yesChemistry – A European Journal, Accepted Article.
N,N‐Bis(trifluoromethyl)aminoacetonitrile (CF3)2NCH2CN (1) that is accessible via a simple single‐step protocol is establish­ed as building block for the introduction of the (CF3)2N group. The two reaction sites of 1, the methylene unit and the nitrile (cyano) group, provide access to different organic substance classes.

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Elucidating the structures of substituted adamantyl esters and ethers using rotational spectroscopy and computations

open access: yesChemPhysChem, Accepted Article.
Adamantane derivatives are promising candidates in the design of new materials with unique properties. In this study, we investigated the molecular structure of a series of adamantyl esters and ethers with an increasing substituent size using broadband rotational spectroscopy.
