Abstract Accommodation is the ability of the eye to adjust its lens thickness to alter the refractive power through the contraction of ciliary muscles. The loss of accommodation ability due to aging leads to presbyopia, a condition in which the eye is unable to focus on near objects. Glaucoma is a disease that vision is impaired due to damage of the retinal ganglion cell at the optic nerve head (ONH) region, which is the leading cause of irreversible blindness worldwide. The biomechanical theory of glaucoma suggests that the deformations of ONH tissues could (directly or indirectly) drive retinal ganglion cell death.… More >

Abstract The molecular dynamics (MD) simulations were used to understand the heat transfer process between the gas phase and the solid skeleton in the nanoporous silica aerogels. The amorphous silica nanoparticles were generated by the MD simulations and the energy accommodation coefficient (EAC) between the gases and the nanoparticles was calculated based on the results of the nonequilibrium molecular dynamics (NEMD) simulations. The apparent thermal conductivity (ATC) of the gases between the heat source and heat sink was also obtained. The effects of the temperature, the particle diameter and the molecule type on the EAC and the ATC were investigated. The… More >
