Ambient blade-coated perovskite solar cells with high reverse bias stability enabled by polymeric hole transporter design

open access: yesNature Communications
Reverse bias stability remains a critical challenge for inverted perovskite solar cells (PSCs). While self-assembled monolayers (SAMs) boost efficiency, their low breakdown voltages limit device reliability.

Antiferromagnetic spin-coupling between MnII and amminium radical cation ligands: models for coordination polymer magnets [PDF]

open access: yes, 2008
One and two electron oxidation of the manganese(II) complex [L2Mn(hfac)2] {L = 4'',4'''-di-tert-butyl-2',2'',2'''trimethoxy-{4-(4'-diphenylaminophenyl)pyridine} were studied by ultra violet/ visible/ near infra red spectroscopy, cyclic voltammetry and ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

2D Coordination Polymer [Fe(piv)2(dab)2]n

open access: yesMolbank
The interaction of preorganized iron(II) pivalate complexes with aromatic N-donor ligand (pyridine (py) or 2,2′-bipyridine (bpy)) and 1,4-diaminobutane (dab, putrescine) in anhydrous acetonitrile yielded a new 2D coordination polymer [Fe(piv)2(dab)2]n (1,

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
