21. He worked on aspects of theoretical solid state physics , that included the properties of organic semiconductors. 22. Throughout his career, his specialties were photochemistry, electron diffraction, magnetic resonance, solid state physics , and neurochemistry. 23. Skyrmions as topological objects are important in solid state physics , especially in the emerging technology of spintronics. 24. Nernst helped establish the modern field of physical chemistry and contributed to electrochemistry, thermodynamics and solid state physics . 25. The Fermi energy is one of the important concepts in the solid state physics of metals and superconductors. 26. He has been a distinguished professor of nuclear physics and solid state physics in many universities of Pakistan. 27. A great deal of modern solid state physics as produced today stems from this original and early paper. 28. He made contributions to quantum mechanics, radio wave propagation in the atmosphere, solid state physics , and information theory. 29. His work is cited in the classical book " Introduction to Solid State Physics " by Charles Kittel. 30. In 1975 he was invited to the USA to Cornell University's Laboratory of Atomic and Solid State Physics .
