Anomalous temperature dependence of speed of sound of bulk poly(N-isopropylacrylamide) hydrogels near the phase transition

Walker, Ezekiel; Reyes Contreras, Delfino; Krokhin, Arkadii; Neogi, Arup (Ultrasonics, 2014-02-12)

Bulk Poly(N-isopropylacrylamide) (PNIPAm) hydrogels are thermally responsive polymers that undergo a sharp volumetric phase transition around its lower critical solution temperature of 33 C. The physical characteristics ...
Coupled Resonator Acoustic Waveguides-Based Acoustic Interferometers Designed within 2D Phononic Crystals: Experiment and Theory

Martínez Esquivel, David; Méndez Sánchez, Rafael Alberto; Heo, Hyeonu; Martínez Argüello, Ángel Marbel; Mayorga Rojas, Miguel; Neogi, Arup; Reyes Contreras, Delfino (Wiley-VCH GmbH, 2023-12-06)

The acoustic response of defect-based acoustic interferometer-like designs, known as Coupled Resonator Acoustic Waveguides (CRAWs), in 2D phononic crystals (PnCs) is reported. The PnC is composed of steel cylinders arranged ...
Funneled focusing of planar acoustic waves utilizing the metamaterial properties of an acoustic lens

Walker, Ezekiel; Reyes Contreras, Delfino; Mayorga Rojas, Miguel; Krokhin, Arkadii; Neogi, Arup (SPIE, 2014-09)

Metamaterial acoustic lenses are acoustic devices based on phononic crystal structures that take advantage of negative or near-zero indices of refraction. These unique properties arise due to either the antiparallel ...
Pulsed Laser Fragmented Carbon Black Powders for the Synthesis of Carbon Nanodots

Reyes Contreras, Delfino; Camacho López, M.; Buendía González, Leticia; Camacho López, M. A.; Squires, B; Neogi, Arup (Int J Opt Photonic Eng, 2022-05-07)

The pulsed laser fragmentation in liquid media of carbon black (CB) powders using picosecond (ps) laser pulses to produce photoluminescent carbon nanodots (CNDs) is reported. A 1064 nm Nd:YAG pulsed laser with a repetition ...
Tunable ultrasonic phononic crystal controlled by infrared radiation

Walker, Ezekiel; Reyes Contreras, Delfino; Mayorga Rojas, Miguel; Krokhin, Arkadii; Neogi, Arup; Wang, Zhiming (APPLIED PHYSICS LETTERS, 2014-09-07)

A tunable phononic crystal based ultrasonic filter was designed by stimulating the phase of the polymeric material embedded in a periodic structure using infrared radiation. The acoustic filter can be tuned remotely using ...
