The release rate of a drug molecule from a porous support depends on a large number of factors, including support characteristics, surface functionalization (procedure and linker type), drug features, biological receptor fluid characteristics, and release conditions. Model-based (in-silico) modulation of the release rate through influential parameters can help in designing an optimized delivery...

Gelatin is considered as a partially degraded product of collagen and it is a biodegradable polymer which can be used to produce scaffolds for tissue engineering. Three-dimensional, porous gelatin scaffolds were fabricated by thermally induced phase separation and freeze-drying method. Their porous structure and pore size were characterized by scanning electron microscopy. Scaffolds with differ...

3D nanofibrous chitosan-polyethylene oxide (PEO) scaffolds were fabricated by electrospinning at different processing parameters. The structural characteristics, such as pore size, overall porosity, pore interconnectivity, and scaffold percolative efficiency (SPE), were simulated by a robust image analysis. Mouse fibroblast cells (L929) were cultured in RPMI for 2 days in the presence of variou...

Three activated carbons are synthesized in a rotary reactor at different activation times. The adsorption isotherms of the samples are measured The pore size distribution of the samples is determined using combined Saito and Foley method, BJH method. An average potential function has been determined inside the cylindrical pores. The effect of activation time on the pore size distribution sample...

Highly porous and well interconnected titanium dioxide (TiO(2)) scaffolds with compressive strength above 2.5 MPa were fabricated without compromising the desired pore architectural characteristics, such as high porosity, appropriate pore size, surface-to-volume ratio, and interconnectivity. Processing parameters and pore architectural characteristics were investigated in order to identify the ...

Bamboo-structured carbon nanotubes are grown on Co-Mo/MCM-41 catalyst in the temperature range of 873-973 K by thermal chemical vapor deposition of acetylene. This study shows that the purified carbon nanotubes have open tips and the metals of the catalyst are not encapsulated. Thus, the bamboo-structure seems to grow from the base. Pore size distribution of the product is quite narrow and ...

Filtration media are required to have suitable pore size, pore size distribution, pore volume, pore surface area and permeability for performing satisfactorily in applications. It is difficult to encounter all the desired properties in a filtration medium. In this investigation, we have characterized filtration media by flow porometry, used these pre-characterized filtration media to design com...

introduction: poroscopy is a method of identification in which the characteristics of sweat pores are compared from different aspects. these pore openings are present along the friction ridges found on the distal end of digits, palms and soles in the hands and feet. materials amd methods: this study enrolled 100 iranian males from the fars family who resided in khorasan razavi province. the ave...
