Synthesis of sodium alginate/carboxy-methyl cellulose/Cu-based metal-organic framework composite for adsorption of tetracycline from aqueous solution: Isotherm, kinetic and thermodynamic approach

Atefeh Ehsani et al.

Summary: Sodium alginate/carboxy-methyl cellulose/Cu-based metal-organic framework (SA/CMC/Cu-BDC) nano-composite beads were prepared and characterized. The composite beads exhibited high surface area and showed promising adsorption capacity for Tetracycline (TC) antibiotic. The adsorption process followed Langmuir isotherm model and pseudo-second-order kinetic model. Thermodynamical analysis suggested that the adsorption of TC onto the composite beads was spontaneous and endothermic. The interactions of hydrogen bonding, electrostatic, and 7C-7C played significant roles in the adsorption process.

The effect of elastic yarn tension and alignment on the tensile and compression characteristics of weft-knitted spacer fabrics for cushioning applications

Mohammad Amirifard et al.

Summary: This research aims to improve the compressive properties of spacer fabrics by incorporating elastic yarns with various tensions and alignments in the surface layers. The presence of spandex yarn and increased tension enhance energy absorption and dissipated compression energy while reducing fabric resiliency and thickness changes. However, an increased number of miss stitches of spandex yarn decrease energy absorption and increase fabric thickness changes.

A unified approach for stress wave propagation in transversely isotropic elastic and poroelastic layered media

Mohammad Shokrollahi et al.

Summary: A complete solution is presented for stress wave propagation in multi-layered alternatively saturated and dry transversely isotropic elastic media in the frequency domain, where hysteretic damping in the soil skeleton has also been considered. The u-p formulation of Biot's poroelastodynamic theory is considered for the governing equations of the porous layers, while equations of motion of single-phase media are utilized for dry layers. The proposed generalized reflection and transmission matrices are employed to satisfy the compatibility conditions. Some numerical evaluations for simpler cases are presented to show the validity of the solution. Physical aspects of surface permeability, hysteretic damping, anisotropy, and underground water level are studied parametrically to justify the behavior of the solutions, and to discover the physical effects of different parameters involved in the subject.
