Other Notes
所有缓冲液的 pH 值都取决于温度和浓度。Tris 缓冲液，温度每降低 1°C，pH 值增加约 0.03 个单位，每稀释十倍 pH 值降低0.03-0.05 个单位。
对于精确的应用，使用经过精心校准的 pH 计和玻璃/甘汞组合电极。

An acquisition method that does not increase scan time or specific absorption rate is investigated for reducing the deleterious effects of cerebrospinal fluid (CSF) partial volume effects on diffusion tensor imaging (DTI) tractography. It is based on using a shorter

A rhenium tris-carbonyl derivative has been designed to couple infrared and luminescent detection in cells. Both spectroscopies are consistent with one another; they point out the reliability of the present SCoMPI (for Single Core Multimodal Probe for Imaging) for bimodal

Nanoparticles in contact with cells and living organisms generate quite novel interactions at the interface between the nanoparticle surface and the surrounding biological environment. However, a detailed time resolved molecular level description of the evolving interactions as nanoparticles are internalized
