X-ray diffraction (XRD) and Energy-dispersive X-ray fluorescence spectrometer (EDXRF) are employed to investigate the microstructure of bulk specimens grown through the Bridgman technique and traveling heater process, respectively. We investigate the lattice parameters, grain sizes, and microstrains of the two grown samples. For a crystal grown by the vertical Bridgeman method, the vacancy serves as an acceptor, resulting in p-type conduction, whereas the vacancy expected to serve as a donor, occurring in n-type conduction for the crystal grown via the traveling heater technique. The concentration of crystal grown via the VBM is determined to be p-type, whereas the concentration of that grown via the THM is n-type. Concerning crystal, the determined crystallite sizes obtained to be 165 and 182 nm for the VBM and THM, respectively.

Crystal Structural Editing: Novel Biaxial MgTeO Crystal as Zero-Order Waveplates.
Adv Mater

State Key Laboratory of Crystal Materials and Institute of Crystal Materials, Shandong University, Jinan, 250100, China.
Waveplates are important optical components to control the polarization of light. Currently, they are often fabricated from uniaxial crystals, and there is no report about waveplates based on the biaxial crystals. In this work, a novel biaxial crystal MgTeO with a structure constructed by 0D TeO groups is designed and grown as waveplate materials for the first time.

The periodontal ligament (PDL) is a connective tissue, and PDL cells have a potential to differentiate into cementoblasts, osteoblasts, and gingival fibroblasts. This study investigated whether transcription factor c-Myb could induce differentiation of PDL cells for periodontal regeneration. PDL cells were isolated from extracted teeth and cultured.

Space life science has been a frontier discipline in the life sciences, aiming to study the life phenomena of earth organisms and their activity patterns under the special environment of space. This review summarizes studies in various key topics in space life science, namely, how microbiome changes in humans and plants, the development of space agriculture and the use of animal, plant and cell models to study the effect of space environments on physiology. We highlight the new possibilities of using high-quality protein crystals uniquely available when grown under space conditions to aid drug development on earth, and the state-of-the-art Bioregenerative Life Support Systems (BLSS) to achieve long term human survival in space.

Due to the limited active sites and poor conductivity, the application of tungsten disulfide (WS) in alkaline water electrolysis remains a challenge. Herein, Ni-WS nanosheet arrays were in situ grown on the carbon fiber paper (Ni-WS/CFP) as an electrocatalyst for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline media, and the introduction degree of Ni can be regulated by adjusting the electrodeposition time. When the electrodeposition time is 3 min, Ni ions are doped into the lattice of WS, and by prolonging the electrodeposition time to 10 min, the nickel disulfide (NiS) crystal phase is generated to form NiS@WS heterojunction.
