一般說明

四甲基氢氧化铵（TMAH）是一种市售的季铵碱，其碱度明显高于氢氧化铵。

應用

四甲基氢氧化铵溶液（在 H2O 中为 10 wt.%）可用作：      
  • 一种在 IPA 中使用 2-（3，4-环氧环己基）乙基三甲氧基硅烷（ECTMS）通过溶胶-凝胶法合成环氧多面体低聚倍半硅氧烷（EPOSS）的反应物。     
  • 一种用于修饰 SnO2 纳米晶体的离子液体，可作为钙钛矿太阳能电池中的有效电子传输层。

TMAH 由于其高硅蚀刻速率，也可用作硅的各向异性蚀刻剂。使用 TMAH 的主要优点是，由于不存在碱离子，它不会对电路造成危险。

The conservation of sleep across all animal species suggests that sleep serves a vital function. We here report that sleep has a critical function in ensuring metabolic homeostasis. Using real-time assessments of tetramethylammonium diffusion and two-photon imaging in live mice

A new water-soluble conjugated polymer containing fluorene and boron-dipyrromethene repeat units in the backbones (PBF) that exhibits red emission was synthesized and characterized. Cationic PBF forms uniform nanoparticles with negatively charged disodium salt 3,3'-dithiodipropionic acid (SDPA) in aqueous solution through

Several applications of high throughput genome and transcriptome sequencing would benefit from a reduction of the high-copy-number sequences in the libraries being sequenced and analyzed, particularly when applied to species with large genomes. We adapted and analyzed the consequences of

The prospect of enhancing the condensation rate by decreasing the maximum drop departure diameter significantly below the capillary length through spontaneous drop motion has generated significant interest in condensation on superhydrophobic surfaces (SHS).

Potassium homeostasis is crucial for living cells. In the yeast Saccharomyces cerevisiae, the uptake of potassium is driven by the electrochemical gradient generated by the Pma1 H(+)-ATPase, and this process represents a major consumer of the gradient. We considered that
