Javier Pérez-Ramírez and colleagues have prepared mesoporous ZSM-22 zeolite by controlled silicon extraction in aqueous sodium hydroxide.

The generation of auxiliary mesoporosity has implications for the catalytic applications of this zeolite.

Using nonlinear optical crystals for second harmonic generators is an exciting field, and in this CrystEngComm Hot article, a high quality single crystal of K₃B₆O₁₀Br has been grown using a topseeded solution growth method. The crystal shows excellent second harmonic generation properties, three times better than KH₂PO₄

This work is particularly significant as this is the first time a single crystal of this type has been synthesised that is large enough to  demonstrate NLO properties.

Vanadium oxides with various connectivities of distorted VO₆ polyhedra are characterized by tremendous structural diversity, which make them a seemingly huge playground for solid-state chemists.

In this exciting CrystEngComm Hot Article, Sarbajit Banerjee et al. describe a novel seeded growth strategy to obtain nanostars of VO₂ and V₂O₅.

The synthetic strategy offers a reproducible alternative to previous approaches for growing octahedral microcrystallites and nanostars with star, snowflake, and asterisk geometries.

In this CrystEngComm Hot article, Jon Zubieta and colleagues at Syracuse University, review the solid state coordination chemistry of three coordination polymers (1,2,4-triazole, 1,2,4-triazolate and 4-pyridyltetrazolate).

This study on the recent literature gives an excellent insight into the latest developments in this field, including important structural trends and stucture/property correlations.

In this CrystEngComm Hot Article, Songjun Zeng, Qibin Yang et al. demonstrate a simple lanthanide doping route for modifying the crystal structure (crystal phase, shape, size and physical properties) of monodisperse multifunctional NaYbF4 nanocrystals.

Lanthanide-doped UC nanocrystals attract attention due to their novel UC emission properties and potential applications in optics, biolabels, colour displays and as light-emitting diodes.

When compared with conventional bioimaging materials, Ln doped UC nanocrystals are considered the most appropriate candidates for biological fluorescent labels due to weak autofluorescence, deep penetration of non-invasive NIR excitation, low radiation damage and photobleaching.
