Chitons are marine molluscs that mineralize their teeth by the process of matrix-mediated biomineralization. The teeth develop in a continuous manner forming hard minerals, including magnetite, making analysis of the matrix within these mineralized regions difficult. This article describes the use of charge contrast imaging techniques, rarely applied to biological samples, to simultaneously image the organic and mineral phases within the teeth of these animals. Resulting evidence demonstrates the power of this technique in delivering architectural information concerning both the matrix and mineral phases, without the need for removal of the hard mineralized material.

Perovskite nanocrystals (NCs) with their excellent optical and semiconductor properties have emerged as primary candidates for optoelectronic applications. While extensive research has been conducted on the 3D perovskite phase, the zero-dimensional (0D) form of this promising material in the NC format remains elusive. In this paper, a new synthesis strategy is proposed.

Recent reconnaissance geochemical investigations have unveiled Cryogenian magmatism linked to the compressional accretionary phase, contributing to the growth of the Afif Terrane in the eastern Arabian Shield. The Cryogenian Suwaj intrusive suite, within the Afif Terrane, displays a compositional range from gabbro-diorite to tonalite-granodiorite. The uniform compositional variation is primarily due to magmatic differentiation within parental magma across multiple pulses.

Livestock manure, a common fertilizer in Chinese agriculture, can lead to environmental contamination and potential health risks due to elevated antibiotic and phosphorus levels. Importantly, the high phosphorus levels initiates transformations of phosphate minerals in soils, especially calcareous soils. These variations in phosphate mineralogy can significantly impact the migration and fate of antibiotics within the soil.

Quadruple perovskite oxides have received extensive attention in electronics and catalysis, owing to their cation-ordering structure and intriguing physical properties. However, their repertoires still remain limited. In particular, piezoelectricity from quadruple perovskites has been rarely reported due to the frustrated symmetry-breaking transition in A-site-ordered perovskite structures, disabling their piezoelectric applications.

Phase separation plays a crucial role in many natural and industrial processes, such as the formation of clouds and minerals and the distillation of crude oil. In metals and alloys, phase separation is an important approach often utilized to improve their mechanical strength for use in construction, automobile, and aerospace manufacturing. Despite its importance in many processes, the atomic details of phase separation are largely unknown.
