A good-performing fuel is generally one that achieves a high ignition mass flux with a low maximum temperature to avoid slag problems due to ash melting [30], which hampers the diffusion of the species and reduces the energy of the bed.
For this reason, the matrix of mitochondria from the heart, brain, and skeletal muscle is a hard gel, which excludes or greatly hampers the diffusion of small molecules [ 133, 134].
The question is: How to recover distribution grid costs equitable without hampering the diffusion of solar power?
Besides, nanostars are usually produced with polyvinylpyrrolidone (PVP) in dimethylformamide (DMF), thus demanding an extensive cleaning of the particles before the encoding process (PVP is retained at the gold surface after the synthesis, hampering the diffusion and adsorption of the SERS probes at the particle).
While spectacular patterns have been demonstrated on metal surfaces, there have been fewer studies of the spontaneous organization of supramolecular networks on semiconductor surfaces, where the formation of covalent bonds between organics and adatoms usually hamper the diffusion of molecules and their subsequent interactions with each other.
The transfer of Igs through the endothelium appeared to be merely a result of diffusion although their large molecular size may hamper the diffusion.
However, beyond tumor vasculature, there are additional biological barriers that are intrinsic to tumor parenchyma, which effectively hamper the diffusion of the carriers thus reducing their therapeutic efficacy.
The low cost of formalin, being less expensive than brand substitute products, and also being readily available in the market by many suppliers and in different convenient formats has hampered the diffusion and research of alternatives.
However, even in such powerful models, the BBB, which regulates the composition of the central nervous system interstitial fluid by allowing low-molecular weight and lipid compounds to pass while at the same time restricting access of water-soluble compounds and macromolecules, may well hamper the diffusion of chemotherapeutic agents to glioma cells [ 98].
In fish culture, for example, the occurrence of genotype−environment interactions are frequently investigated because they may hamper the diffusion of genetic gain in different rearing environments and thus be undesirable (Fishback et al. 2002; Kause et al. 2004; Maluwa et al. 2006; Saillant et al. 2006).
From this analysis, we identified poor regulatory design, lack of market demand, and some institutional characteristics of the construction sector as the key systemic barriers that hamper the diffusion of green energy innovations in the Dutch housing sector.
