Mimicking biological enzymes may be key to hydrogen fuel production UofIllinois NatureComms
with rigid square planar porphyrins or pincer ligands is difficult, as is evidenced by the lack of spectroscopic evidence of metal-centered paramagnetic states in the aforementioned catalysts.complexes supported by mixed hard-soft NCHS2 and NCBrS2 ligands, which can stabilize Nicomplexes when the ligands become anionic. We propose that the pre-positioning of a proximal C–H bond can be an effective strategy to generate metal hydrides that can participate in hydrogen evolution.
Importantly, these Niat an overpotential of 670 mV in the presence of trifluoroacetic acid . Using a combination of synthetic, spectroscopic, electrochemical, and computational studies, we show that this new class of Ni complexes are able to access the paramagnetic Nistates during electrocatalytic hydrogen evolution. A key C–H activation step is proposed to generate a putative Niintermediate, and we propose that it mirrors the role of the cysteine ligands in [NiFe] hydrogenases.

Polar meron-antimeron networks in strained and twisted bilayers - Nature CommunicationsSliding and twisting of van der Waals layers can produce fascinating physical phenomena. Here, authors show that moiré polar domains in bilayer hBN give rise to a topologically non-trivial winding of the polarization field, forming networks of merons and antimerons.

Different NIPBL requirements of cohesin-STAG1 and cohesin-STAG2 - Nature CommunicationsNIPBL is considered the cohesin loader. Here, the authors report that a drastic reduction of NIPBL levels reduces chromatin-bound cohesin-STAG2 genome wide while cohesin-STAG1 increases and can still be found at CTCF-bound sites but cannot form loops.
