RADS, ASTHMA, COPD. "In healthy individuals, stimulation of sensory nerves may be protective; however, in individuals with airway disease, the heightened response to sensory irritants may exacerbate disease and have a deleterious health impact." https://lnkd.in/ey47aVM View in LinkedIn

TRPA1 IS AN EXTRAORDINARY MOLECULE, playing important roles in snakes, bats, mosquitoes, and man, from sensing heat, cold, various mustards and capsaicin, involved in metabolic control, pain, and neuropsychiatric disorders. Biomolecules are more often known for exquisite specificity and fidelity, but this clever construct has an enormous range of nuanced functions. What a beautiful molecule. View in LinkedIn

SOUND CONTROL. "Phononic crystals will provide new components that offer the same level of control over sound that mirrors and lenses provide over light." https://lnkd.in/ehwDYhR View in LinkedIn

ACOUSTIC INSULATORS. "The existence of structures with complete phononic band gaps has obvious applications. For instance, a phononic crystal will reflect incoming sound waves with frequencies within the gap and can therefore be used as an acoustic isolator." https://lnkd.in/ehwDYhR View in LinkedIn

SUPERLENSES. "Ultrasound, negative refraction and superlenses. One of the hottest topics in optics over the past five years has been the possibility of making “superlenses” with materials that have a negative refractive index." https://lnkd.in/ehwDYhR View in LinkedIn

PHONICS. "Just as photonic band gaps were followed by phononic band gaps, recent progress in making superlenses for electromagnetic waves has prompted efforts to make superlenses for acoustic waves." https://lnkd.in/ehwDYhR View in LinkedIn

METAMATERIAL LENSES. "In general it is not possible for a lens to produce an image that contains details that are finer than the wave-length of the light being focused. However, superlenses made of “negative index” materials can overcome this diffraction limit." https://lnkd.in/ehwDYhR View in LinkedIn

SOUND LENSES. "Negative refraction in phononic crystals is possible due to multiple scattering of sound waves at the solid–air interfaces. The development of superlenses for acoustic waves would be a major breakthrough for a variety of ultra-sound techniques." https://lnkd.in/ehwDYhR View in LinkedIn

"HYPERSONIC phononic crystals could also have a large impact in thermal management. Thermal energy in solids is transported primarily by electrons and phonons. The electronic contribution is important for materials with a large number of free carriers, such as metals. The presence of a phononic band gap would reduce the flow of phonons and therefore the thermal conductivity of a solid." https://lnkd.in/ehwDYhR View in LinkedIn

PHONON LASERS. "A crystal that is “blind” to electromagnetic waves with wavelengths of about several hundred nanometres and “deaf” to sound at similar wavelengths within the crystal...The ability to make structures with both types of band gap could lead to breakthroughs in the field of acousto-optics." https://lnkd.in/ehwDYhR View in LinkedIn
