The study designed a game-based learning(GBL)activity "Historical Battleship," which adopted an educational board game "Voyage with Taiwan" and mobile devices with online searching tasks to support students history learning.Students perceived GBL learning process at different playing stage and their flow experience were probed.The findings showed that students at the stage using board game with mobile device for online searching had more perceived attention,cognitive engagement,discussion within group,and usefulness of history learning,compared with the stage using the board game only.Moreover,students also had high flow experience when playing this board game combined with mobile devices.

金纳米颗粒的表面等离子体共振效应(SPR)在可见光响应光催化领域已得到广泛关注.然而,受光激发后产生的"热电子"其超快能量弛豫过程抑制了它的有效分离利用;基于此,我们提出通过引入具有高功函的电子受体金属(活性催化材料)来促进热电子的有效分离利用.

近年来,随着温室效应的不断恶化,将CO2 转化为其他碳化物再利用已经成为了一项重要的研究方向,然而CO2 的结构十分稳定,需要高能量和适当的催化剂才可以将其转化为可利用的碳资源,严重影响其转化效率.
过氧化氢(H2O2)作为一种环境友好型氧化剂,广泛应用于医疗、废水处理、造纸、纺织、电子工业等行业.传统的"蒽醌自氧化法"生产H2O2 具有能耗高、成本高、降解产物复杂、污染环境等缺点[1].

微囊藻毒素(Microcystins,简称MCs,目前有100 多种异构体 [1]) 是饮用水源(如湖泊、水库等)的主要污染源之一.MCs 是一种肝脏毒素,具有强促肿瘤和致癌作用.
氢气由于绿色环保、燃烧热值高、可由水制得,被认为能够减轻化石燃料过度使用问题的可再生明星能源之一.我们以石墨相氮化碳(g-C3N4)为基础材料,通过构建多尺度纳米结构、高活性异质结构、以及分子结构调控,发展了新方法合成一系列g-C3N4 基催化剂用于光、电催化分解水制氢,包括零维g-C3N4 量子点、一维g-C3N4 纳米纤维、二维g-C3N4纳米片/纳米网片,三维g-C3N4"海藻",以及氮缺陷
石墨相氮化碳作为典型的非金属2D 层状半导体光催化剂而备受关注.但是,常规热聚合所得体相氮化碳因可见光吸收范围有限和强烈的激子束缚能等缺点,而极大的限制了其光催化活性的提升.
In order to solve mechanics problems,force finding in the problem is an indispensable step.Also,this step is often difficult for not only beginners and also learners who have learned.Therefore,there a
