Article Synopsis
  • - Land-use change significantly contributes to biodiversity loss in Africa, yet there has been limited research on future projections due to uncertainties; this study aims to fill that gap by analyzing various land-use scenarios from 2021 to 2100.
  • - The research uses 2020 observational land-use data to evaluate future changes across seven Shared Socioeconomic Pathways (SSP) scenarios, finding strong correlations (0.89) between current and projected land uses.
  • - Projected outcomes indicate a decrease in barren and forest land, while cropland, grassland, and urban areas will likely expand significantly, raising concerns about biodiversity loss and ecosystem health in the region.

Introduction: As an important advanced functional material, the memory effect of nitinol shape memory alloy (SMA) is the focus of research. According to the current research, the memory function of the alloy decreases after welding, and there is no sufficient explanation for the phenomenon.

Objectives: For the problem, this research is to explore the underlying causes of the decrease of shape memory function after welding by analyzing the microstructure and micro defects.

A method to improve the brazing between YSZ and Ti6Al4V by femtosecond laser surface machining is introduced. The highest strength of ~150 MPa (which is 95.2% higher than that of the flat YSZ/Ti6Al4V joint) is achieved when the processing speed is 200 μm/s.

Dynamic evolution of initial instability is investigated by an analytic model obtained by modifying the theory of Warren and Langer [Phys. Rev. E 47, 2702 (1993)] and the quantitative phase-field model in directional solidification under transient conditions for realistic parameters of a dilute alloy.
