Published: December 2020

An examination of manganese silicates and germanates revealed unusual structural motifs and extremely different chemistries, with identical hydrothermal reactions forming KMnSiO versus KMnGeO(OH)(HO). The germanate is exceptional in both its -axis length (exceeding 76 Å) and unit cell volume (nearly 18000 Å), the largest known polygermanate structure to our knowledge.

Ionizing radiation from natural and many synthetic sources is a remarkable tool in many scientific, production, quality control, food preservation, medical, security, and other technological processes. The need to protect humans (public and personnel), gadgets, the environment, and animals from the harmful effects of radiation, while maintaining and expanding the scope of application has made radiation protection an important topic to discuss. Among the methods and materials available for radiation control, shielding and the use of glass shields are the most effective and attractive methods and materials, respectively.

Article Synopsis
  • The study explores the growth and structure of ultrathin iron silicate and iron germanate films on a ruthenium substrate, focusing on how temperature affects their formation.
  • These two-dimensional films serve as simplified models for more complex, catalytically active structures like zeolites, which have applications as catalysts and molecular sieves.
  • Researchers used advanced experimental techniques for real-time analysis and theoretical modeling to reveal that both film systems consist of a two-layer structure, with distinct compositions impacting the arrangement and properties of iron atoms within the films.

Pyroxenes (AMXO) consisting of infinite one-dimensional edge-sharing MO chains and bridging XO tetrahedra are fertile ground for finding quantum materials. Thus, here, we have studied calcium cobalt germanate (CaCoGeO) and calcium cobalt silicate (CaCoSiO) crystals in depth. Heat capacity data show that the spins in both compounds are dominantly Ising-like, even after being manipulated by high magnetic fields.

Er-doped glasses and fibers with broadband near infrared (NIR) emission have been widely applied in EDFA. Limited by optical gain band of Er-doped glasses and fibers, it was hardly meet to the demands of broadband amplification in the C + L band. In this work, six glass matrixes were employed for discussing the influence of glass matrix on the Stark splitting of Er and the wavelength of laser output and amplification.
