Although the Glu-Ala repeats do improve the proportion of correctly cleaved material by preventing steric hindrance of the kex2p cleavage site [ 20, 22].
The metalloporphyrin species abundant at the external surface of FSM-16 supports aluminated by impregnation of purely siliceous material are free of steric hindrances and yield predominantly epoxide.
These indirect effects during fiber degradation could be the release of compounds from the material affecting inhibition or steric hindrance during enzymatic hydrolysis or fermentation.
Civil liberty groups have expressed concerns that the so-called "Closed Material Hearings" (CMPs) would be a massive hindrance to open justice and contesting allegations from the security services.
The main hindrances to the development of these materials are represented by the relatively low capacity (150 mAh g−1), the lower, sloped reaction potential (3.2 3.3 V vs. Li+/Li) compared to the higher, flatter potential of, for example, LiFePO4 (3.4 V vs. Li+/Li) and the lack of lithium/sodium in the initial compound.
Cellulose triacetate is highly beneficial as a polymer material for metal ion removal as it creates minimum hindrance to the transport of ions within the membrane (Flory, 1953).
Taking into account the cell-wall characteristics of sugar cane, it is clear that lignin represents one of the main hindrances to cellulosic ethanol production from this lignocellulosic material.
Being the most oxidized state of carbon, CO2 as a raw material is in its lowest energy level, thus posing a major hindrance in establishing industrial processes.
We believe that the difference in rate constants between a flat surface and porous material may be due in part to the steric and electrostatic hindrance present in biomolecule films on the pores walls, as well as conformational restriction of the surface-tethered strands suppressing biomolecule interactions inside the pores [ 22, 23].
Hydrophilic PEG has been the focus of research as an effective coating material for hydrophobic nanoparticles due to its ability to resist protein fouling and provide steric hindrance preventing nanoparticles from aggregation [34].
