Preferably, the deposited materials are metallic elements which are deposited in layers of thickness in the range from 5 to 50 nm. Optionally, barrier layers are interposed at intervals during the deposition step (a) for the purpose of preventing diffusion across the bulk deposit during the heat...
The resultant effect on the macroscopic moisture barrier properties of the materials were evaluated using water vapour permeability (WVP) measurements. The CR had no significant effect on the WVP, except for one blend of acetylated fat and beeswax for which a slow CR may have favoured the ...
Chemical vapour deposition of metals and metal silicides on the internal surfaces of porous silicon doi:10.1016/0022-328X(92)83450-VCobalt, cobalt monosilicide and rhenium thin films have been deposited on the internal walls of both n- and p-type ... G D.,Anderson,and,... - 《Journal ...
Aerogels, attributable to their outstanding properties and potential applications in diverse fields, have been a major topic of innovative materials research in the last decades. While previously the scientific community has mainly focused on inorganic- and plastic-based aerogels, recent years have ...
However, these are separated by a barrier estimated to be no higher than about 130 cm−1. Thus the two shapes are likely to be parts of the potential energy surface domain that is associated with the most stable shape of urea, i.e. one in which the zero-point vibration covers both ...
is the positively charged K128 which also shows a similar switch of the torsion angles (Supplementary Information Table S1), indicating that this loop and in particular the residue E158 / K128 could serve as the threshold position to overcome the energetic barrier nucle- ating such a large conf...
Remarkably, downsizing of the non-porous Fe(py)2[Pt(CN)4] (py = pyridine) to a thin film of 16 nanometres thickness initiates a gate-opening structural transformation (cp-to-op) induced by the lower potential energy barrier53. At the nanoscale, guests can diffuse in between ...
Finally, the important ICL3 linking the pseudo- symmetrical halves (TM1-5 and TM6-10) of the transporter is also shifted up to B10 Å and forms an additional barrier that closes the channel on the cytoplasmic side (Fig. 5). This two-tier channel block likely ensures that very little ...
On crossing the epithelium barrier, it can cause several diseases, from otitis to pneumoniae and meningitis, mostly in young children and immunocompromised patients. Besides its iron requirement, H. influenzae also displays an absolute haem prerequisite to sustain its aerobic growth, as it is devoid...
Light metal/CFRP-made structural members which are characterized in that they are structural materials in which a CFRP material is stuck to the surface of a light metal material via an adhesive agent layer of thickness at least 10 μm and up to 500 μm, and the volume resistivity of the ...
