Web摘要: 以乙酰丙酮铜和硫粉为铜源和硫源,在油酸(OA)-油胺(OM)-十八烯(ODE)体系中合成了近红外吸收的硫化铜(CuS)纳米颗粒,并通过改变硫元素活化状态的方式调节其吸收峰到适合光热治疗的1 064 nm附近。 通过阳离子交换法进一步制备了Fe、Mn等元素掺杂的CuS纳米颗粒,并保持其吸收峰位置几乎不变。 WebLithium acetylacetonate Product Number : A18464 Supplier : Johnson Matthey Catalog Company Inc. 30 Bond Street, Ward Hill, Massachusetts, 01835??8099 Emergency Telephone Number: (978) 521??6300; CHEMTREC: (800) 424??9300 Alternative Names : Lithium 2,4?pentanedionate 2. COMPOSITION AND INFORMATION ON … Web29 dec. 2016 · Here, we propose that, in the presence of excess acetylacetone (Hacac) and free protons (H+), the reduction can take place between 2.25 and 1.5 V versus Na/Na+ via a one-electron-transfer reduction. This reduction can take place in situ during discharge in a novel hybrid Na-based flow battery (HNFB) with a molten Na–Cs alloy as the anode. how do i shut down facebook page
