木虫 (小有名气)

[求助] 求助一个单位符号 wt % (m/v) ,注意整个是一个符号

最近看了两篇ACS的文献出现了一个单位,不清楚是什么意思,求解答,纳米四氧化三铁 12 wt % (m/v),如果仅仅是写wt% 是质量分数,可后面又加了(m/v),就有些糊涂了

麻烦给个上下文。

有两篇文献是这么表达的
1、Substrate Modification. Preparation of the AIBNSiCl SAM
initiator were carried out by the addition of 0.5 wt % (m/v) of
AIBNSiCl in toluene to clean silicon wafers or ITO in a slide
staining jar. 1 ml of pyridine was added to catalyze the surface
condensation reaction and also to act as an acid scavenger.
The substrates were left in the solution for 12 -24 h to ensure
complete SAM formation of AIBNSiCl. The slides were then rinsed
and sonicated in methanol to remove the pyridinium hydrochloride
salt that was formed in the reaction. The substrates were then stored in isopropanol in a dark cabinet to ensure no decomposition and protection from dust.
2、he composite hydrogels were fabricated
via condensation of hydrazide-functionalized and aldehyde-function-a lized c opolymers dissolved in 10 mM PBS. The hydrazide
functionalized polymer− SPION complex [12 wt % (m/v)] and
aldehyde functionalized polymer solution [2−10 wt % (m/v)] were
loaded into different barrels of a dual-barrel syringe.
