Heterogeneous media consisting of thin layers particles forked porous structure with different physical-chemical properties are widely used in science-intensive technologies and priority sectors industry, medicine, ecology, etc. Such distributed systems pores two main spaces: micro- nanopores macropores cavities between particles. Mass transfer the system heterogeneous causes types mass transfe...

Fungal pores feel the pull S teinberg et al. report that fungi use motor proteins to distribute their nuclear pores around the nuclear envelope. In animal cells, the nuclear lamina holds the nuclear pores in place, ensuring that they are evenly spaced. The lamina prevents nuclear pores from clustering, promoting import of cargoes through the pores and helping to organize the chromosomes, which ...

It is well-known that the Interparticle interactions between adsorbates and surface of an adsorbent can affect the surface morphology. One of the consequences of this issue is that the resonant frequency of a nanoscale resonator can be changed due to adsorption. In this study we have chosen a cantilever-based nanoscale mass-sensor with a single nanoparticle at its tip. Using the classical...

We report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (MTU) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (Au-NPs). This thiol-containing molecule exhibits intriguing affinity with Au-NPs. The reactivity involves the displacement of the citrate shell by the thiolate shell followed ...

The mechanism of the formation of alveolar pores (Kohn's pores) in neonatal male rabbits was studied by scanning electron microscopy and scanning electron microscopic morphometric analysis. The number of alveolar pores per alveolus was increased after birth. About 80 percent f alveolar pores had Type H alveolar epithelial cells on their edges when the rabbits were I-day old. This percentage dec...
