A method is described for the concentration of Salmonella from water. As is done with enterovirus, Salmonella bacteria were concentrated from water in two steps: by pH 3.5 adsorption on and pH 9.5 elution from 8-micron porosity micro-fiber glass filter tubes. This method worked in less than 30 min, and Salmonella typhimurium was inactivated only slightly in spite of rapid pH variations (pH 3.5 ...

abstract porous materials are commonly found in nature and as industrial materials such as wood, carbon, foams, ceramics and bricks. in order to use them effectively, their mechanical properties must be understood in relation to their micro-structures. foam made from non-flammable metal will remain non-flammable and the foam is generally recyclable back to its base material. this research work ...

Porous conducting polymers are intriguing heat harvester candidates. This review focuses on the different strategies to vary porosity range (from micro- macro-pores) and their impact thermoelectric properties.

Pore fluid pressurization, one of the main causes soil instability, is known to be anomalously high for interstitial water in clay submitted undrained heating. This anomaly attributed confinement nanometric micropores. In this work, we use molecular simulation investigate how affects thermo-mechanical properties and a new poromechanical formulation (Laurent Túlio Int J Eng Sci 152:103296, 2020)...

The lignin aerogels that are both high porosity and compressibility would have promising implications for bioengineering field to sound-adsorption and damping materials; however, creating this aerogel had a challenge to adhesive lignin. Here we reported cellulose as green adhesion agent to synthesize the aerogels with strong mechanical performance. Our approach-straightforwardly dissolved in io...

Fibrous filters were fabricated using a novel melt co-extrusion and two-dimensional multiplication technology combined with a high pressure water jet delamination technique. The filters made from polypropylene (PP) / polyamide 6 (PA6) system exhibited micro to nano scale fibers having uniform fiber distribution and superior mechanical properties. Effects of film draw ratio upon co-extrusion on ...

Bone microarchitecture and mineralization were determined at three-dimensional synchrotron radiation micro computed tomography in two inbred mice strains. Distal metaphysis of the left femur was imaged in three dimensions at 6.65 microm, whereas the right femur was analyzed with histomorphometry. Three-dimensional quantitative parameters of trabecular and cortical bone architecture were compute...

A tissue-engineering scaffold resembling the structure of the natural extracellular matrix can often facilitate tissue regeneration. Nerve and tendon are oriented micro-scale tissue bundles. In this study, a method combining injection molding and thermally induced phase separation techniques is developed to create single- and multiple-channeled nanofibrous poly(L-lactic acid) scaffolds. The ove...
