Ferrovalley materials are generally hexagonal lattice systems with a ferromagnetism-valley coupling, in which the intrinsic ferromagnetism can induce valley polarization. However, as of now the number of ferrovalleys found is still limited. In this article, TlX (X = Cl/Br/I) single-layers (SLs) are proposed with a tetragonal lattice structure as well as ferroelectricity-valley coupling.

Thus, high-basicity CaO-SiO-FeO-MgO slag with BO content from 0% to 15% was designed, and its melting characteristics and viscosity were investigated. The influence of BO content on the phase diagram of the slag system was calculated using FactSage 7.

- High iron content in nickel slag primarily occurs in the fayalite phase, and basic oxides can disrupt its stable structure for better utilization.
- The study focuses on the CaO-SiO-FeO-MgO system, examining how varying basicity affects melting characteristics, viscosity, and structural changes.
- Results indicate that with a basicity of 0.90, the system achieves optimal temperatures and viscosity, while higher basicities lead to changes in the silicate network structure and viscosity behavior.

This study investigated the effects of different combinations of irrigation and nitrogen levels on the growth of greenhouse sweet peppers, assessing yield, quality, water use efficiency (WUE), and partial factor productivity from applied N (PFPN). By using controlled drip irrigation, the optimal conditions for efficient, large-scale, high-yield, and high quality production of sweet peppers in Northwest China were determined. Using the local conventional irrigation and nitrogen regime as a control (105% ET, N: 300 kg·hm), three alternative irrigation levels were also tested, at 90%, 75%, and 60% ET.

Objectives: To explore the relation of ultrasonic findings to pathological features in cases of chronic viral hepatitis B and C.
Methods: The ultrasonic and pathological findings were analyzed in 130 patients with chronic viral hepatitis B and 106 with chronic viral hepatitis C.
Results: In patients with hepatitis B, the ultrasonic echo was thicker and more intensive and uneven cords were found.
