“…We have also demonstrated that gas‐phase turbulence and bulk chemical reactions can impact film growth significantly. Although there remain many challenges in understanding indoor surfaces, 57 overall, the model should be applicable to a wide range of laboratory and field measurements as these become available.…”

Large surface area‐to‐volume ratios indoors cause heterogeneous interactions to be especially important. Semi‐volatile organic compounds can deposit on impermeable indoor surfaces forming thin organic films. We developed a new model to simulate the initial film formation by treating gas‐phase diffusion and turbulence through a surface boundary layer and multi‐layer reversible adsorption on rough surfaces, as well as subsequent film growth by resolving bulk diffusion and chemical reactions in a film. The model was applied with consistent parameters to reproduce twenty‐one sets of film formation measurements due to multi‐layer adsorption of multiple phthalates onto different indoor‐relevant surfaces, showing that the films should initially be patchy with the formation of pyramid‐like structures on the surface. Sensitivity tests showed that highly turbulent conditions can lead to the film growing by more than a factor of two compared to low turbulence conditions. If surface films adopt an ultra‐viscous state with bulk diffusion coefficients of less than 10−18 cm2 s−1, a significant decrease in film growth is expected. The presence of chemical reactions in the film has the potential to increase the rate of film growth by nearly a factor of two.

“…These results suggest that weak interactions, such as halogen bonding, can play substantial roles in controlling the speed at which multiphase transformations occur in the atmosphere and on indoor surfaces. [21][22][23][24][25] Rudich and co-workers 6 observed that classes of chemical reactions that occur slowly in the gas phase (k < 10 À15 cm 3 molecules À1 s À1 ), due to high activation barriers, are enhanced at monolayer organic surfaces that mimic tropospheric aerosol; in some cases by many orders of magnitude. For example, the reaction of bromine atoms with saturated aliphatic lms occurs 10 000 times faster than predictions based upon analogous reactions in the gas phase.…”

“…Vascular endothelial growth factor (VEGF) activates unfolded straight linear protein response sensors in the endoplasmic reticulum through phospholipase C gamma which mediated crosstalk with mammalian target of rapamycin complex 1 (mTORC1) in the regulation of angiogenesis [28]. Indicates the involvement of the synthesis of VEGF-A during the effects of phospholipase and mitochondrial enzymes on Pro-TOR protein during the binding with FOX transcription factor for re-synthesis pyrimidine and leucine amino acids for preparation for sestrin-1 synthesis.…”

RORs isoforms are so active biological molecules in lipid metabolism and in fat biosynthesis, that strongly dependent on and regulated by OPA1 mitochondrial genes and its active mitochondrial enzymes where each of mitochondrial enzyme (phospholipase, synthase, and synthetase) is responsible for its own ROR isoform {phospholipase responsible for ROR-alpha synthesis, synthase responsible for ROR-beta synthesis, and synthetase responsible for ROR-gamma synthesis} for acting and functioning the long fatty acids molecules “which produced from the effects of ATPase and COX enzyme on lipid molecules which accompanied and associated with absorbed nutrient molecules (pro-lipo-nutrient -mTOR molecules)”, and then will follow its own pathway in fatty and amino acids biosynthesis, in active anti-inflammations biosynthesis, and then will follow its own functions in original cells proliferations. Where, Lipid molecules+ATPase+COX enzymes ¬¬>long Fatty acids molecules +mitochondrial active phospholipase + ribosomal ATPase (in a control limit) ¬-> long Fatty acid-acyl-CoA phospholipase (which is ROR-alpha active isoforms), ¬¬>>Fatty acyl-CoAsynthase which is ROR beta active genes, And ¬¬>> fatty acyl-CoA-synthetase (which is ROR-gama isoforms) then both ROR-alpha and ROR-gama +AMP ¬> isopentanyl PP+ Leu (or Meth) amino acids ¬> leu-pentapeptides (or Meth-pentapeptides) active molecules for activating enkephalin tissue in brain. ATPase and COX enzymes are responsible for acting on lipid associated with nutrients-mTOR for producing long fatty acids molecules which will be affected by mitochondrial phospholipase, synthase and synthetase to form ROR-alpha, ROR-beta and ROR-gamma respectively.
