Synthesis of Primary Amines via Reductive Amination of Aldehydes and Ketones Over a Ni‐Doped MFM‐300(Cr) Catalyst

open access: yesAdvanced Science, EarlyView.
Reductive amination of aldehydes and ketones to primary amines with high selectivity and yield can be achieved over Ni‐doped MFM‐300(Cr) in the presence of NH3 and H2. In situ inelastic neutron scattering, coupled with modeling, reveals that cooperativity between Ni active sites and MFM‐300(Cr) affords an optimal microenvironment for the selective ...

Highly Oriented Epitaxial Hexagonal Boron Nitride Multilayers on High‐Temperature‐Resistant Single‐Crystal Aluminum Nitride (0001)

open access: yesAdvanced Science, EarlyView.
High‐temperature‐resistant single crystals of aluminum nitride works best for multilayer hexagonal boron nitride (hBN) epitaxy and annealing on large‐area dielectric wafers, promising for large‐scale integration and device applications of hBN. Abstract The epitaxy of high‐quality hexagonal boron nitride (hBN) multilayers on dielectric wafers is ...

Mechanism‐Aware Digital Twin for High‐Temperature Creep Prediction in Mo–Re Alloys

open access: yesAdvanced Science, EarlyView.
A digital twin framework enables real‐time monitoring of creep in refractory alloys and reveals dislocation‐drag‐induced Re segregation to grain boundaries. Inspired by this, La2O3 dispersion is introduced to suppress dislocation motion — concurrently mitigating Re segregation and enhancing creep resistance.

Giant Magnetocaloric Effect in a Honeycomb Spiral Spin‐Liquid Candidate

open access: yesAdvanced Science, EarlyView.
The frustrated honeycomb‐lattice single‐crystal GdZnPO, a spiral spin‐liquid (SSL) candidate, exhibits a giant magnetocaloric effect (with a large Grüneisen parameter Γm = 4.4 T−1) and exceptional cooling performance near the crossover magnetic field (Hc), surpassing other known magnetocaloric materials.
