This experiment tests the risk of pH changes in organic materials. Containment in carbon dioxide for three days had no effect on the pH of the four materials tested. -- AATASanders, SherriSanders S (1987) Effects of CO2-fumigation on pH. ICOM Committee for Conservation, 8th Triennial Meeting...
而CLSM则利用具有荧光色素DHPDS在不同pH下荧光波长的改变来标定电极扩散层中溶液的平均pH环境(Figure 2c-2d)。 Figure 2. (a) pH-dependent SEIRA spectra of 0.5 M phosphate solutions with corresponding band assignments; (b) ph...
Stunning method had a significant effect on pH values (P < 0.001) as well as on pH decline (P < 0.01). The lowest pH was found at 24 h post-slaughter in G1 and the highest one on G5. The greatest drop in pH (pH0–pH24) was found in G1 ...

通过对不同[K+]下*COatop的振动Stark effect的研究发现(Figure 5a-5c),Stark 斜率在不同[K+]下并没有改变,说明不同[K+]下电极表面的局部电场强度并没有改变,所以证实加入K+后CO2R FE的提升并不是由于K+引入的局部电场效应引起的。但是加入K+后,电极表面的溶剂水环境发生了明显的改变(Figure 5d):具有较...

Here, through the co-immobilization of carbonic anhydrase, we study the effect of CO2 hydration on the local environment and performance of a range of disparate CO2 reduction systems from enzymatic (formate dehydrogenase) to heterogeneous systems. We show that the co-immobilization of carbonic ...
Pyropia haitanensis, a commercially important species, was cultured at two CO2 concentrations (390×10−6 and 700×10−6 (parts per million)) and at low and high nutrient levels, to explore the effect of elevated CO2 on the species under nutrient enrichment. Results show that in CO2-enric...
Effect of pH on the Nitrite Hydrogenation Mechanism over Pd/Al2O3 and Pt/ Al2O3: Details Obtained with ATR-IR Spectroscopy It is well-known that activity and selectivity to N2 during nitrite hydrogenation over noble metal catalysts in water depend on the pH of the solution, but... SD Eb...
