查询词典 energy surface

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。

Thermogravimetry curve shows that NiOH embedded in AAO decomposed slowly compared to thin film.

可能存在两个原因：氧化钛纳米丝具有比氧化钛纳米膜更大的比表面积；氧化钛纳米丝的光学带隙大于氧化钛纳米膜的，带宽的增加，使得价带电子电位变得更正，导带电位变得更负，这实际上增加了光生电子和空穴的氧化还原能力，提高了半导体光催化氧化有机物的活性。

Pyronine B adheres to on the surface of CdS and prevents CdS aggregating, which leads to the decrease of fluorescence quantum yield of CdS. Fluorescence resonance energy transfer happens from CdS to Rhodamine B, Butyl rhodamine B and Rhodamine 6G, respectively. There is a higher FRET efficiency between CdS and Neutral red with the value being 0.282. Moreover, coupling reaction between -NH_2 of Neutral red and -COOH of CdS -TGA leads to red shift of CdS fluorescence spectrum. The reaction also occurs between Safranine T and CdS. At the same time, the Fluorescence of ST is quenched by forming ST -CdS ground state complex. Chapter 6, CdS QDs modified by chitosan and polyethyleneimine can be quenched by Cu~(2+). According to the experimental result, we develop the novel sensor for Cu~(2+).

研究结果，吡啰红与CdS之间作用形式是染料聚集在CdS的表面使得CdS不易聚集，但同时也降低了CdS的发光的量子效率；罗丹明B、罗丹明6G、丁基罗丹明B均与CdS之间存在能量转移，位阻效应使得能量转移效率最高的BRhB的相对荧光强度增大最小；中性红与CdS的能量转移效率更高，同时推测可能使CdS-TGA上的-COOH与部分NR的-NH_2发生偶联导致粒子变大而发生荧光光谱的红移；番红花红与CdS是相互荧光猝灭，可能是ST的-NH_2与CdS-TGA上的-COOH发生偶联使得纳米粒子变大以及二者形成基态复合物的共同作用的影响。
