Moreover, the higher peak intensity ratio of 1763 cm1/1801 cm1 also reveals the predominant role of intramolecular ester condensation in anhydride formation in Eudragit E film.doi:10.1016/S0032-3861(98)00488-1Shan-Yang LinHui-Ling YuMei-Jane Li...
This process is characterized by a red shift in SPR, leading to the emergence of a peak at 600 nm, while the initial peak at 525 nm diminishes. The intensity of the 600 nm peak increases proportionally to the analyte concentration, as observed in Fig. 6a. Among the biogenic amines tested...
In Fig. 2a (the 5 P primer), the component peak I at a binding energy of 533.0 eV is attributed to the C–O bond22. The component peak II at 531.5 eV may be assigned to the P–O–H bond23,24. Component peak III located at 530.3 eV is mostly attributed to Zr–...
1.In this paper,two typical explosive hazardous chemicals were selected,one is double base propellant,and the other one is multi-nitro ester propellant.本文选取了2种典型爆炸性危险化学品——双基发射药和混合硝酸酯发射药作为研究对象,使用了C80微量量热仪、热重-红外光谱联用仪(TG-FTIR)、气相色谱-质谱...

(for *COOMe formation) and heat-induced desorption. In contrast to the Ru/Nb2O5analog, the Ru/NbOxcatalyst showed a distinct peak at 1750 cm−1, confirming its efficiency in generating *COOMe (Supplementary Figs.10,11). The time-resolved FTIR experiments were conducted at 150 °C to ...

Afterwards, we quenched the ?bers in a water bath for 8 h, then dried them overnight in a laboratory hood and subsequently overnight in a vacuum oven at room temperature. We quantitatively assessed ?ber acetylation using FTIR spectroscopy (i.e., absorption peak centered around 1748 cm); ...

Focusing on the changes in the peaks of the (0 5 1) and (5 0 1) planes of Na-ZSM-5, the peak intensity gradually decreased upon heating under CH owing to the increased lattice vibrations. In addition, the diffraction peak shifts to a higher angle. The zeolites exhibited a negative ...
