Boron is a component of neodymium magnets (Nd 2 Fe 14 B), which are among the strongest type of permanent magnet. These magnets are found in a variety of electromechanical and electronic devices, such as magnetic resonance imaging (MRI) medical imaging systems, in compact and relatively small motors and actuators .

Boron is a trace element that is naturally present in many foods and available as a dietary supplement. It is a structural component of plant cell walls and is required for plant growth, pollination, and seed formation [1].

Boron is a metalloid and was discovered by Joseph L. Gay-Lussac and L. J. Thénard in 1808. It is chemically unreactive and is the second hardest element on earth. Boron is an ancient metal and have been known to human civilization since thousands of years.

2022年4月19日 · The boron 2 was one of the best racquets in its time (early 90's) but it wouldn't hold a candle to a modern racquet as technology has moved on quite a bit now. I'd suggest you keep it in good condition (cut and remove all the strings to take the stress off the frame) and sell it for a modern racquet if you are looking to get back into playing.

某君小勇，今隐其名，皆余昔日打野球时损友；分隔多年，消息渐阙。 日前偶闻其一大病；适归故乡，迂道往访，则仅晤一人，言病者其弟也。 劳君远道来视，然已早愈，赴某地踢场矣。 因大笑，出示日记二册，谓可见当日病状，不妨献诸发烧友。 持归阅一过，知所患盖“中毒狂”之类。 语颇错杂无伦次，又多荒唐之言；亦不著月日，惟墨色字体不一，知非一时所书。 间亦有略具联络者，今撮录一篇，以供JS研究。 记中语误，一字不易；惟人名虽皆网名，不为世间所知，无关 …
