Navier-Stokes transport coefficients for a model of a confined quasi-two-dimensional granular binary mixture

Vicente Garzo et al.

Summary: The Navier-Stokes transport coefficients for a confined quasi-two-dimensional granular binary mixture of inelastic hard spheres have been determined using the Boltzmann kinetic equation. The results show explicit forms for the diffusion transport coefficients, shear viscosity coefficient, and quantities T-i((1)) and zeta((1)) under steady state conditions. These coefficients are not limited to specific values of concentration, mass, and/or size ratios, and apply in principle to arbitrary degrees of inelasticity. Furthermore, the violation of Onsager reciprocal relations for a confined granular mixture is quantified in terms of the parameter space of the problem.

Enhanced norfloxacin degradation by visible-light-driven Mn3O4/γ-MnOOH photocatalysis under weak magnetic field

Ning Li et al.

Summary: A valence-state heterojunction Mn3O4/gamma-MnOOH was synthesized for efficient norfloxacin degradation under magnetic field assisted visible light, with enhanced charge carrier transfer and inhibiting recombination of electron-holes, as well as providing more active sites for photocatalysis. The opposite Lorentz forces contribute to attractive interactions between norfloxacin and the catalyst, accelerating norfloxacin degradation with lower active energy. This study sheds new lights on an innovative strategy of magnetic field assisted photocatalysis for refractory contaminants remediation from water.

Rational design of pore structures for carbon aerogels to significantly increase adsorption of tetracycline from water using batch and fixed-bed operation

Wen-Cui Xu et al.

Summary: A novel method for fabricating 3D porous carbon nanofiber/graphene oxide composite aerogels was developed for antibiotic removal from water, which showed significantly enhanced adsorption capacity due to the adjustable pore structure. The adsorbent effectively removed antibiotics over a wide pH range and exhibited lower inlet pressure in fixed-bed column adsorption compared to traditional particle adsorbents. The main possible mechanisms for the adsorption of antibiotics on the adsorbent included pi-pi electro-donor-acceptor interaction, pore filling, and hydrogen bonding.
