Formation of Large Native Sulfur Deposits Does Not Require Molecular Oxygen
Frontiers in Microbiology, 2019 Large native (i.e., elemental) sulfur deposits can be part of caprock assemblages found on top of or in lateral position to salt diapirs and as stratabound mineralization in gypsum and anhydrite lithologies. Native sulfur is formed when hydrocarbons come

(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3
Chemistry – A European Journal, EarlyView.The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers
Chemistry – A European Journal, EarlyView.ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Versatile nitrate-respiring heterotrophs are previously concealed contributors to sulfur cycle
Nature CommunicationsHeterotrophic denitrifiers play crucial roles in global carbon and nitrogen cycling. However, their inability to oxidize sulfide renders them vulnerable to this toxic molecule, which inhibits the key enzymatic reaction responsible for reducing nitrous ...

High Pressure and Road to Room Temperature Superconductivity
, 2018 High pressure serves as a path finding tool towards novel structures, including those with very high Tc.The superconductivity in sulfur hydrides with record value (203 K) is caused by the phonon mechanism.

Chemistry – A European Journal, EarlyView.New redox‐active oligothioguanidines are developed and used in dehydrogenative P–P coupling reactions and hydroquinone oxidations. Tetrathioguanidino‐ and tetraguanidinobenzenes oxidize high‐potential halogenated hydroquinones faster than relatively low‐potential hydroquinone.

Isotope shift in the Sulfur electron affinity: observation and theory
, 2010 The electron affinities eA(S) are measured for the two isotopes 32S and 34S (16752.9753(41) and 16752.9776(85) cm-1, respectively). The isotope shift in the electron affinity is found to be positive, eA(34S)-eA(32S) = +0.0023(70) cm-1, but the ...

Self‐Complementary Dimers Based on Zwitterionic Halogen Bond Donors
Chemistry – A European Journal, EarlyView.In this study we present the first isolated zwitterionic homodimers based on halogen bonding (XB). After optimization of the structures by changing the Lewis base (LB) and the backbone, their dimerization was observed in gas phase, as well as, in solid state.
