Due to the low molecular weight and viscosity, ETCs are successfully intercalated to the clay gallerys, what is evidenced by XRD showing a down-shift of basal plane peak of layered silicate along with TEM investigation.
Raman analysis shows that the intensity ratio of D to G bands (ID/IG) of nanotubes increases with the melamine amount and position of G-band undergoes a down-shift due to increasing nitrogen doping.
X-ray photoelectron spectroscopy indicates that the surface Pd atoms donate more electrons to the overlap with the sub-layer atoms, suggesting a strengthened d-hybridization and a down-shift of d-band center relative to the Fermi level on the surface.
Plot of the averaged current/voltage (I/V) relationship of Ih in the presence or absence of SKF83959 reveals a down-shift of the I/V curve, and an enhancement of the maximal steady-state current amplitude (from −70 to −120 mV, Fig. 3B).
Likewise, all three major bands of APP responded to PNGaseF with a down-shift.
EndoH, in contrast, left the upper two bands of APP unchanged, but induced a down-shift of the lowest band.
During strawberry flower development, a down-shift of temperatures below 2°C translates into injury to reproductive organs from early stages of bud development until the flower opens.
In the NMR spectrum, there was a down-shift of the peak of CH2 protons neighboring to OH group of PEG to 4.25 ppm from 3.65 ppm that confirmed the formation of PEG-VPA.
Replacement of the oxygen isotopes from O2 to O2 in A1 results in a down-shift of −46 cm−1 for the O O stretch vibration, in agreement with experiment, where a value of −45 cm−1 was reported.
A down-shift in the peak at 1575 to 1566 cm−1 suggests a potential loss of double bond character of the C17-C18 bond.[ 23] This conclusion is supported by the time-resolved IR data collected for a Chlide only sample (i.e. C17-C18 bond is reduced), which show a significant feature at about 1570 cm−1 that is not present in the Pchlide data.
Because K-to-Q mutation has been commonly used to generate an acetylated lysine mimic due to chemical similarity of an acetamide and the Gln side chain (e.g., PMID: 23904479; 19303850; 21906795), such mutation may not generate enough structural change of the protein to cause a down-shifting of the band.
