Inhalation of air-dispersed sub-micrometre and nano-sized particles presents a risk factor for animal and human health. Here, we show that nasal aerodynamics plays a pivotal role in the protection of the subterranean mole vole Ellobius talpinus from an increased exposure to nano-aerosols. Quantitative simulation of particle flow has shown that their deposition on the total surface of the nasal ...
Nanophotonic technique has been attracting much attention in applications of nano-bio-chemical sensing and energy conversion of solar energy harvesting and enhanced energy transfer. One approach for nano-bio-chemical sensing is surface plasmon resonance (SPR) imaging, which can detect the material properties, such as density, ion concentration, temperature, and effective refractive index in hig...
We propose to use the intrinsic two-level system (TLS) defect states found naturally in integrated optomechanical devices for exploring cavity QED-like phenomena with localized phonons. The Jaynes-Cummings-type interaction between TLS and mechanics can reach the strong coupling regime for existing nano-optomechanical systems, observable via clear signatures in the optomechanical output spectrum...
We show that a graphene sheet perforated with microor nano-size antidots have prominent absorption resonances in the microwave and terahertz regions. These resonances correspond to surface plasmons of a continuous sheet “perturbed” by a lattice. They are excited in different diffraction orders, in contrast to cavity surface plasmon modes existing in disconnected graphene structures. The resonan...
We discuss subwavelength-scale semiconductor metal-optic resonators placed on the metal substrate with various top metal plate sizes. Albeit with large optical losses, addition of metal layers converts a leaky semiconductor nano-block into a highly-confined optical cavity. Optically pumped lasing action is observed with the extended top metal layer that can significantly suppress the radiation ...
We present a loss-coupled distributed feedback microlaser, monolithically grown on standard 300-mm Si wafer using nano-ridge engineering. The cavity is formed by integrating metallic grating top of the nano-ridge. This allows forming laser without etching III-V material, avoiding damaged interfaces and associated carrier loss. Simulations, supported experimental characterisation modal gain devi...
فرآیند ماشینکاری به روش تخلیه الکتریکی( edm)، یکی از فرآیندهای نوین ماشینکاری است که کاربردهای متنوعی در ساخت و تولید محصولات میکرومتری دارد. رشد و توسعه نانوتکنولوژی و نیاز به بهره گیری از روشهای جدید موجب شده است که جذبه زیادی برای استفاده از فرآیند edm در ساخت و تولید محصولات نانومتری ایجاد شود. فرآیند nano-edm یک فرآیند ماشینکاری حرارتی است که در آن از انرژی حرارتی حاصل از جرقه الکتریکی برا...
