Article Abstract
Novel bioinorganic hybrid materials based on proteins and inorganic clusters have enormous potential for the development of hybrid catalysts that synergistically combine properties of both materials. Here we report the creation of hybrid assemblies between a computationally designed symmetrical protein Pizza6-S and different polyoxometalates with matching symmetry: the tellurotungstic Anderson-Evans (Na6[TeW6O24]·22H2O) (TEW); Keggin (H4[SiW12O40]·6H2O) (STA); and 1 : 2 CeIII-substituted Keggin (K11[CeIII[PW11O39]2]·20H2O) (Ce-K). This results in the formation of complexes with clearly defined stoichiometries in solution. Crystal structures validate the complexes as building blocks for the formation of larger assemblies.

Bimorph soft actuators, traditionally composed of two materials with distinct responses to external stimuli, often face durability challenges due to structural incompatibility. Here, we propose an alternative design employing free-standing, isostructural heterogeneous Janus (IHJ) films that harmonize stability with high actuation efficiency. These IHJ films were fabricated through a vacuum self-assembly process, consisting of TiCT MXene nanosheets and hybrid graphene oxide (GO)-biomass bacterial cellulose (BC), with a well-matched two-dimensional lattice structure.

Designing heterostructure-based nanocomposites has gained considerable interest in solving energy scarcity and environmental contamination issues. Herein, a heterojunction assembly of ternary SnS/MoS/g-CN nanocomposites with varying Sn and Mo weight ratios was synthesized through a single-step hydrothermal method. At an optimized ratio of tin to molybdenum (1 : 2), denoted as SM-3, promising electrochemical and photocatalytic performances were observed compared to bare SnS/g-CN and MoS/g-CN.

Background: Aflatoxin B1 (AFB1) is a highly carcinogenic mycotoxin frequently found in contaminated food products, posing a significant threat to public health and food safety. Therefore, the development of rapid, sensitive, and reliable detection methods for AFB1 is critical for early warning and prevention. However, traditional detection techniques often require expensive equipment, skilled personnel, and complex procedures, limiting their suitability for on-site applications.

We present a supramolecular templating strategy for inducing chirality in hybrid perovskites via confined crystallization within chiral super spaces-nanoconfined, helically ordered cavities formed by the self-assembly of achiral bent-core molecules with chiral additives. Upon removal of the additives, the resulting porous films retain permanent chirality. Quasi-2D hybrid organic-inorganic perovskites crystallized within these templates exhibit distinct chiroptical activity, including mirror-image circular dichroism and circularly polarized light emitting (CPLE), with CPLE dissymmetry factors reaching up to 1.

Heterostyly is a polymorphic floral adaptation controlled by supergenes. The molecular basis of distyly has been investigated in diploid species from several unrelated families, but information is lacking for polyploid systems. Here, we address this knowledge gap in Schizomussaenda henryi, a tetraploid distylous species of Rubiaceae, the family with the greatest number of heterostylous species.
