Metastable, , kinetically favored but thermodynamically not stable, interstitial solid solutions of carbon in iron are well-understood. Carbon can occupy the interstitial atoms of the host metal, altering its properties. Alloying of the host metal results in the stabilization of the FeC phases, widening its application.

Water-soluble metal-organic cages (WSMOCs) show high potential as antitumor agents, while the targeted functionalization of WSMOCs toward enhanced antitumor performances is a challenging task. Herein, WSMOCs were functionalized with donor-acceptor (D-A) systems for synergistic photothermal-chemotherapy. Octahedral [ML] cages based on a 2,4,6-tri(2-pyridine-4-yl)-1,3,5-triazine (TPT) acceptor and M(bpy) (M = Pd for , Pt for ) nodes were functionalized with tetrathiafulvalene (TTF) to form and .

We report a scalable method based on continuous-flow reactors for conformally coating the surfaces of facet-controlled Pd nanocrystals with uniform, ultrathin shells made of Pt. The key to the success of such an approach is the identification of a proper polyol to generate the Pt atoms at a relatively slow rate to ensure adequate surface diffusion and thus the formation of uniform shells in a layer-by-layer fashion. We first demonstrate the concept using the production of Pd@Pt (n = 2-5) core-shell icosahedral nanocrystals and then have the strategy successfully extended to the syntheses of Pd@Pt cubic and octahedral nanocrystals.

Lanthanum strontium ferrite (LaSrAgFeO = 0; LSFO) and its silver-doped derivative (LaSrAgFeO = 0.05; LASFO) are synthesized using mild conditions by a sol-gel method. Both oxides present a perovskite-like structure with orthorhombic symmetry due to octahedral tilting; thus, the incorporation of silver in the A-site does not significantly modify the perovskite structure.
