Garnet‐like luminescence upon Ce3+‐activation is found in the first six representatives Li9RESi4N4O8 (RE = Y, La, Gd, Dy, Yb, Lu) of the substance class of lithium rare‐earth oxonitridolithosilicates, which also show a novel structure type. High‐temperature solid‐state synthesis yielded crystalline samples for single‐crystal X‐ray diffraction‐based ...

A Review on MXene Terminations
Surface terminations play a decisive role in determining the properties of MXenes. Their coordination, composition and stoichiometry can be tuned both during synthesis and through post synthesis methods to tailor MXenes for optimum performance in applications. This review explores the present understanding of surface terminations.

Inducing Chirality and Chiral Instabilities in Ferrogels with Homogenous Magnetic Fields
By pre‐aligning magnetic particles into chains, significant chiral deformations are induced by fixing the base of a cylindrical actuator and applying a homogeneous magnetic field. Subsequent base rotation can drive the system into metastable states. Further rotation or reduction of field strength triggers a chiral instability, characterized by a switch

A scalable bio‐templated approach using spray‐coating and thermal annealing fabricates cellulose nanofibril (CNF) films loaded with gold nanoparticles (Au NPs) and graphene oxide (GO) hybrids as Surface‐enhanced Raman scattering (SERS) substrates. The 3D CNF network ensures uniform Au NPs distribution, while annealing induces more hotspots, confirmed ...

Programmable Entanglement of Granular Mechanical Metamaterials
This paper introduces entangled granular metamaterials—clusters of complex grains whose interlocking drives emergent, tunable properties. Here, we identify geometric features that enable entanglement and quantify them via disentanglement dynamics. We demonstrate robotic handling where magnetically controlled grains achieve robust collective picking and

Reformulation of Electromagnetism with Differential Forms
Classical electromagnetism is a well-established discipline. However, there remains some confusions andmisunderstandings with respect to its basic structures and interpretations. For example, there is a long-lasting controversy on the choice of unit systems. There are also the intricate disputes over the so-called EH or EB formulations.
