2021年5月，清华大学化学系曲良体教授和程虎虎博士团队开发了一种异质膜湿气发电材料和器件（Moisture-enabled electric generator, MEG），能够利用空气中水汽直接产生电能，实现了低湿度环境下的高电压产出，集成MEG成功输出上千伏电压，为新型清洁能源的开发和社会的可持续发展提供了新的能量转化利用思路。该成果近期发表于《自然 纳米技术》(Nature Nanotec...
向天然气管道中注入乙二醇并进行回收再利用是深水气田开发中防止水合物生成的重要技术手段，但当采出水中的二价盐含量较高时会造成管道或MEG 再生系统的堵塞、结垢和腐蚀等问题，导致常规乙二醇再生系统不能正常生产。为此开发了一种新的乙二醇再生工艺，即在MEG 富液中加入碱液使M2+生成沉淀物，然后采取过滤分离的方式脱掉二价盐再进行再生。通过室内模拟实验，对富乙二醇中二价阳离子脱除影响因素和操作条件进行了研...
天文学家已经发现了一个遥远的世界，其轨道远远超出了冥王星，位于太阳系的极远端。这颗天体的非正式名称为L91，它可能正处于逐步从奥尔特星云——一个彗星和其他冰冻天体的大本营——向同样冰冷的柯伊伯带转移的过程中。天文学家之前从未在其他天体中观察到这样的现象。
Conversational Interaction in the Scanner: Mentalizing during Language Processing as Revealed by MEG
conversational interaction episodic working memory
2015/12/18
Humans are especially good at taking another’s perspective—representing
what others might be thinking or experiencing. This “mentalizing”
capacity is apparent in everyday human interactions and conv...

Subjects (n=12) listened to the synthesized syllable tokens ba, da, ma, and na. Evoked magnetic fields were recorded using a 93-sensor whole-head biomagnetometer array while subjects performed a same-...
The role of temporal predictability in semantic expectation: An MEG investigation
Prediction Expectation Semantic
2015/9/2
Prior research suggests that prediction of semantic and syntactic information prior to the
bottom-up input is an important component of language comprehension. Recent work in
basic visual and audito...
A lexical basis for N400 context effects: Evidence from MEG
Semantic priming Semantic anomal Prediction
2015/9/2
The electrophysiological response to words during the ‘N400’ time window (300–500 ms post-onset) is
affected by the context in which the word is presented, but whether this effect reflects the ...

An MEG experiment was carried out in order to compare the processing of lexical-tonal and intonational contrasts, based on the tonal dialect of Roermond (the Netherlands). A set of words with identica...
Investigating phonological processing by varying pronounceability: MEG Evidence
Investigating phonological processing varying pronounceability
2014/11/12
For words and pronounceable non-words, the M350 did appear to be inversely related to word frequency, as found in previous studies (Embick et. al., 2001). We did, however, find an M350 peak for the f...
