Description: SEM image of an inner ear “hair cell” responsible for detecting sound within the cochlea. No one understands how these microstructures assemble and last over a lifetime of sound (since they cannot regenerate) making them highly researched in cell biology.

Description: This work presents the replication of shark skin dermal denticles using Glancing Angle Deposition (GLAD) atop line seeds. GLAD represents a highly advanced physical vapor deposition process that, when coupled with line seeds meticulously prepared through conventional photolithography, enables the creation of intricate three-dimensional micro/nanostructures on surfaces. These structures, in turn, impart exceptional properties, including superhydrophobicity, antifouling, and reduction in drag forces.The fabrication process was executed by Luca Caruso, a dedicated summer Research Experience for Undergraduates (REU) student, within the state-of-the-art cleanroom facilities at the University of Louisville.

Description: This image offers a fascinating glimpse into the intricate world of a rose petal, as observed through a scanning electron microscope. Rose petals exhibit a unique property known as para-hydrophobicity. This means that while water droplets adhere to the surface, they do so with a notably high contact angle. This remarkable characteristic is a result of the petal's complex structure, featuring a combination of nanoscale stripes on microscale hemispheres. Interestingly, when the petal undergoes desiccation, the microscale hemispheres lose their plumpness. The petal's surface reveals a series of repetitive formations resembling Devils Towers. Devils Tower, a natural wonder located in Wyoming, rises over 5000 feet above sea level. It is distinguished by its surface with hexagonal columns. This geological marvel holds deep cultural significance as a symbol and object of reverence for Native American communities.
