First-principles, spin-relaxed pseudopotential plane wave calculations show that Ti atoms can form a continuous coating of carbon nanotubes at different amounts of coverage. Fully relaxed geometry has a complex but regular atomic structure. The semiconducting tube becomes ferromagnetic metal with high quantum conductance. However, the magnetic properties of Ti− coated tubes depend strongly on the geometry, amount of Ti coverage and also on the elastic deformation of the tube. While the magnetic moment can be pronounced significantly by the positive axial strain, it can decrease dramatically upon the adsorption of additional Ti atoms to those already covering the nanotube. Besides, the electronic structure and the spin-polarization near the Fermi level can also be modified by radial strain.

Introduction: Psychological science is undergoing a period of change and transformation. Statement of the Problem: The crisis in confidence over psychological science has led to an emphasis on larger and larger sample sizes, sustaining an unfortunate neglect of single-subject research designs in undergraduate education. Literature Review: We identified several excellent articles advocating for the benefits of single-subject and small N designs over group-based research designs, yet single-case designs are seldom taught at undergraduate level. Teaching Implications: Teachers of psychology are provided with resources for implementing training in single-case research designs at undergraduate level, enabling students to draw objective conclusions in an N-of-1 research report. We do this using an example from a recently developed module on wellbeing science. Conclusion: Embedding an underused methodological approach for determining objective change in single individuals into undergraduate psychology curricula will help to develop practical skills applicable to many roles in the discipline of psychology, the healthcare sector and the quantified-self community.
