Beyond Canonical CO Oxidation: Structural and Evolutionary Insights Into a Non‐Canonical Carbon Monoxide Dehydrogenase

open access: yesAngewandte Chemie, EarlyView.
Clade B carbon monoxide dehydrogenases (CODHs) remain enigmatic, diverging from canonical CODHs in structure and function. Here, we present the first characterization of Ruminococcus flavefaciens CODH (RfCODH), revealing occluded substrate pathways and attenuated CO oxidation activity.

Solvent‐Induced Structural Modulation in Nanoscale Covalent Organic Frameworks Enables High‐Performance NO2 Sensing

open access: yesAngewandte Chemie, EarlyView.
Solvent intercalation disrupts the stacking order of protonated porphyrin‐based 2D COF nanoparticles, resulting in a less compactly packed structure with increased accessibility of porphyrin sites. This structural modulation leads to significantly enhanced chemiresistive NO2 sensing performance.

Crosslinking of Linear Polyimines Into Aminal‐Linked Porous Organic Polymers for C2 Hydrocarbon/Methane Separation

open access: yesAngewandte Chemie, EarlyView.
Crosslinking of linear polyimines with aromatic diamines via nucleophilic addition converts nonporous polyimine precursors into aminal‐linked porous networks, offering a new strategy for synthesizing porous organic polymers. The resulting materials exhibit high C2 hydrocarbon adsorption capacity, excellent selectivity over CH4, and durable cyclic ...

Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System

open access: yesAdvanced Science, EarlyView.
An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

Forma

open access: yesEstudos Kantianos [EK], 2019
Apresentação do conceito de forma, ao qual se aplica o adjetivo de conformidade a fim no juízo de gosto. Trata-se de mostrar como Kant concebe a forma dos objetos belos na terceira Crítica, indo desde uma definição genérica e ampla como síntese do múltiplo do fenômeno até a especificação tomada como formalista pela tradição de comentários, ou seja ...

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing

open access: yesAdvanced Science, EarlyView.
Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds
