Advanced Functional Materials, EarlyView.A strategic spin‐polarization suppression in Fe single‐atom catalysts is proposed to enhance electrocatalytic reduction of NO to NH3. Employing a top‐down electrospinning strategy, self‐supported FeSAC with Fe‐N3S1 coordination structure and spin‐state transition is engineered from high‐spin to low‐spin.

Development of PDC Bit with Axe-shaped Teeth and its Application in East China Sea
Shiyou jixie, 2021 The PDC bits used in many wells in the East China Sea had low ROP and small footage in the process of drilling deep formation. After the bits were pulled out, it was found that the cutting teeth had been worn severely.

Effects of vibrational nonequilibrium on the inviscid design of an axisymmetric nozzle for hypersonic flow [PDF]
An axisymmetric, hypersonic nozzle for arc-heated air is described. The method of characteristics is used to compute an inviscid nozzle contour in which vibrational nonequilibrium is approximated by the sudden-freeze technique.

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing
Advanced Functional Materials, EarlyView.A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...

Advanced Functional Materials, EarlyView.Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.
