Electron microscopy imaging of nanoporous polymers at sub-nanometre resolution is difficult due to insufficient electron contrast of polymers.
Considerable interest exists in the development of novel n-type conjugated polymers, since many currently available polymer systems have insufficient electron mobility and/or electron affinity.
The high rate applications such as electric vehicles of the traditional lithium ion batteries (LIBs) are commonly limited by their insufficient electron conductivity and slow mass transport of lithium ions in bulk electrode materials.
Below −1.6 V of external cathodic voltage, the ZnO NRAs could not be formed due to the insufficient electron supply under a low external cathodic voltage.
During denitrification, N2O can form when insufficient electron donor is available, when the pH is excessively high, when sufficient copper is lacking, or when inhibitors of the N2O reductase, such as DO, hydrogen sulfide, high nitrite (({text{NO}}_{2}^)) or ammonia (NH3) concentrations, are present (Tallec et al. 2008; Bergaust et al. 2010; Lu and Chandran 2010; Pan et al. 2012, 2013a).
Several surface loops and residues were not modeled due to insufficient electron density.
The region comprising the α4 α5 joining loop, which might constitute part of the entrance to the cavity, was not modelled in the structure of Ce-FAR-7 due to insufficient electron density.
Of the 182 residues of CalU16, the first 4 residues, the last 2 residues, and a dynamic loop containing 19 residues (a.a. 141 159) from subunit A and 15 residues (a.a. 144 158) from subunit B were not modeled due to insufficient electron density.
As at low temperatures, the thermal energy (k B T) is insufficient to allow electrons to hop to their nearest neighbours.
This could be due to an insufficient transfer of electrons from Pdx to the P450 as CYP154H1 and CYP101A1 (the natural monooxygenase partner of PdR and Pdx) share only 26% sequence identity on protein level.
Hacking worried that the simple manipulation of the first quotation, the changing of the charge on an oil drop or on a superconducting niobium sphere, which involves only the charge of the electron, was insufficient grounds for belief in electrons.
