“…A more advanced description of the flow through the spatial system of capillaries in the form of meandering channels is also found in Brinkhman [ 79 ]. The literature on the subject discusses other models of hydrodynamics of single and multiphase fluids flowing through porous media, taking into account the influence of fluid properties and the type of porous medium on the flow through granular beds [ 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 ]. A separate group of the practical use of the gas permeability methods is studies on the quality assessment of construction materials, particularly concretes [ 88 , 89 , 90 , 91 , 92 ].…”

With regard to the problem of gas flow through isotropic porous deposits, the issues were considered in the category of description of gas movement mechanisms for structural models of the skeleton. As part of experimental tests of gas permeability through porous material in the form of polyamide, the numerical simulation method was used, using the k–ε turbulence model. The analysis of hydrodynamic phenomena occurring in the porous material made it possible to confront experimental research with numerical calculations. The analysis shows that, for a porous polyamide bed, there is a certain limit range of gas velocity (10−4–1) ms−1 at which flow resistance is the lowest. On the other hand, the highest value of the flow resistance is gradually achieved in the range of gas velocity (1–10) ms−1. This is due to the different structure of the isotropic polyamide material. The validation of the numerical model with experimental data indicates the validity of the adopted research methodology. It was found that the permeability characteristics of the tested porous material practically did not depend on the direction of gas flow. For porous polyamide, the permeability characteristic is non-linear, which, from the point of view of the measurements carried out, indicates the advantage of turbulent gas flow over its laminar movement. The novelty of the article is a proprietary method of measuring gas permeability for a cube-shaped sample made of a material constituting a sinter of spherical particles of equal dimensions. The method enables the determination of gas flow (in each flow direction) in microchannels forming an orthogonal network, characteristic of isotropic materials.

“…The 1-D hexagonal and 3-D cubic OMCs were prepared using the nanocasting method, which employed ordered mesoporous silica as hard templates [43][44][45][46][47][48][49][50][51][52] and acidied sucrose as a carbon source. Likewise, all the MNCs were also synthesized using SBA-15 silica as a hard template 53,54 and the precursors used for synthesizing these N-doped carbons are ethylene diamine, pdiaminobenzene, aniline, pyrrole, and polyvinylpyrrolidone (PVP).…”

“…Compared with mesoporous silicon materials, mesoporous carbon materials have several special excellent properties, such as high specific surface area and porosity, adjustable pore size, controllable pore wall composition and structure, simple synthesis, and a lack of physiological toxicity. At the same time, high thermal and hydrothermal stability and extremely large specific surface area and pore volume can be obtained by optimizing and controlling the synthesis conditions, thus making this type of material very promising for a wide range of applications, including in adsorbent carriers [20,36], catalyst supports [37,38,39], hydrogen storage materials [40,41,42], and electrode materials [43,44,45].…”

Food safety is one of the most important and widespread research topics worldwide. The development of relevant analytical methods or devices for detection of unsafe factors in foods is necessary to ensure food safety and an important aspect of the studies of food safety. In recent years, developing high-performance sensors used for food safety analysis has made remarkable progress. The combination of carbon-based nanomaterials with excellent properties is a specific type of sensor for enhancing the signal conversion and thus improving detection accuracy and sensitivity, thus reaching unprecedented levels and having good application potential. This review describes the roles and contributions of typical carbon-based nanomaterials, such as mesoporous carbon, single-or multi-walled carbon nanotubes, graphene and carbon quantum dots, in the construction and performance improvement of various chemo-and biosensors for various signals. Additionally, this review focuses on the progress of applications of this type of sensor in food safety inspection, especially for the analysis and detection of all types of toxic and harmful substances in foods.
