In general , two forms of combinatorial library synthesis exist , " liquid-phase " synthesis and " solid-phase " synthesis ; in the latter the chemistries are performed with one or more of the reagents attached to an inert solid support such as a bead or column .
Other companies are also trying out new chemistries and materials , at the positive and negative terminals of the battery .
其他公司同样尝试着在电池的正负极上使用新的化学制剂和材料。
U.s. department of energy ( doe ) research is currently focused on lithium chemistries .
能源部的研究近期集中在锂电上。
Car batteries come in different capacities , have different recharging speeds and use different chemistries which have their own recharging criteria .
汽车电池有容量上的差异,充电速度的差异以及化工成分的差异,具备自身的充电标准。
In my first clinical experience , I was learning a strange new color code : red-top tube for blood chemistries , purple top for hematology , green top , yellow top , and so on .
