Which acid and base react to form water and sodium sulfate? When a strong acid reacts with a weak base, what will the resulting solution be? What are the chemical equations for the first ionization step of carbonic acid? How do you write an ionic equation for the dissoluti...
EFFECT OF H2S ON CORROSION BEHAVIOR OF X70 STEEL IN WEAK ACID SOLUTIONSH2S对X70钢在弱酸性溶液中的腐蚀行为的影响H2SX70钢腐蚀用静态失重法,动电位扫描法,交流阻抗法结合扫描电镜研究了H2S对X70钢在弱酸性溶液中的腐蚀行为的影响.结果表明,在25℃,pH=4.6的HAC-NaAC体系中,加入0.04mmol/L的H2S会大幅度加速...
That is perhaps due to the distinct behavior of the cathodic polarization curves observed in the presence of H2S, as compared to those obtained in strong acids solutions or in the presence of other weak acids such as carboxylic acids and carbonic acid. In the presence of aqueous H2S, the ...
. Drought-induced hormone (i.e., ABA, salicylic acid (SA), jasmonic acid (JA) and ethylene) and ROS signals vary among plants, which promote the accumulation of H2S in guard cells and initiate the signals downstream of H2S to induce stomatal closure (Deng et al.2020; García-Mata and ...
5. This illustrates that the H2S dimer is much floppier than the H2O dimer. The wave functions shown in Supplementary Fig.6have nodal planes that depend on at least two intermolecular coordinates. Due to the strong coupling of these coordinates the excited states are mostly of mixed character....
Based on the experiences of previous studies, RDG elucidates the strength of interactions revealing weak and strong interactions of the studied systems69,70,71. Hence, the peaks at the low-density surface of RDG maps were used herein to explain the interactions between enrofloxacin and the ...
It has been reported that the Michaelis constant Km of 3MP for 3MST is 4.08 mM15 and this affinity is relatively weak. Some 3MP(substrate)-like inhibitors of 3MST, such as pyruvate and 3-mercaptopropionic acid, also show inhibition constant Ki values of several mM15,17. Nevertheless, ...
When non-nanomotor PTM without movement ability and mitochondrial targeting ability was placed in chamber I, chamber II and chamber III showed similar weak fluorescence intensity (Fig. 4c and d). When the chamber I was placed with nanomotor-based H2S donor PCM with mitochondrial targeting ...
While single-reactable probes 2 and 3 showed relative strong fluorescence under simi- lar test conditions. These results implied that the combined usage of FRET-ICT dual-quenching effects is more efficient than that of any FRET or ICT single-quenching effect. After reacting with H2S, the probe ...
