屏幕作为建筑元素的发展历程

立面和立面设计是建筑的基本要素,媒体立面是立面设计相对较新的分支领域。文章概述了媒体立面的设计与研究过程,并以六个项目为例介绍立面设计涉及的元素与子元素如何与通信技术相互结合。     

北非1942

<正>前言本情景的制作缘起于编辑部送给我的一盒威龙北非兵人。怎奈因诸事扰之,期间停工半年有余,致使整个制作周期长达一年两个月。停工虽打乱了制作的节奏,但却使我有机会沉淀下来总结自己这几年模型制作的心得。所以,本情景可以说是我为了求证自己这些感悟对与错的一个实验性作品。我将本情景的背景设定在1942年北非的突尼斯,德军北非军团501重型坦克营一辆三号N型坦克和一辆82侦察车相聚于某一小镇,装甲兵和侦察车成员正在相互交流情报,而一些装甲掷弹兵则在休整补充物资。     

共享时间开放平面幼儿园:未来学前教育建筑的提升

正当今的教育毫无疑问是日新月异的,各种新的因素在不断涌入这一领域和教育市场。在各个等级的教育上都能看到纵向和横向的变化。大学教育要么走向线上,要么通过实体或虚拟形式的教育全球化在世界各地拓展品牌分支。例如,芬兰的小学正致力于各种传统学科融合为贯通知识的整体方法。在荷兰,史蒂夫·乔布斯学校是小学个性化教育的旗手,并取得了骄人的成果。幼儿园也在发生各种变化,像蒙特梭利和华德福这样的成功模式得以进一步升级,像我们父辈那时一样因循守旧的幼儿园建筑设计和空间变化尤为明显。这正是共享时间幼儿园发展的道路,并对原有的成功教育模式进行升     

Amination of biochar surface from watermelon peel for toxic chromium removal enhancement

Watermelon peel residues were used to produce a new biochar by dehydration method. The new biochar has undergone two methods of chemical modification and the effect of this chemical modification on its ability to adsorb Cr(VI) ions from aqueous solution has been investigated. Three biochars, Melon-B, Melon-BO-NH_2 and Melon-BO-TETA, were made from watermelon peel via dehydration with 50% sulfuric acid to give Melon-B followed by oxidation with ozone and amination using ammonium hydroxide to give Melon-BO-NH_2 or Triethylenetetramine(TETA) to give Melon-BO-TETA. The prepared biochars were characterized by BET, BJH,SEM, FT-IR, TGA, DSC and EDAX analyses. The highest removal percentage of Cr(VI) ions was 69% for Melon-B,98% for Melon-BO-NH_2 and 99% for Melon-BO-TETA biochars of 100 mg·L~(-1) Cr(VI) ions initial concentration and 1.0 g·L~(-1) adsorbents dose. The unmodified biochar(Melon-B) and modified biochars(Melon-BO-NH_2 and Melon-BO-TETA) had maximum adsorption capacities(Qm) of 72.46, 123.46, and 333.33 mg·g~(-1), respectively.The amination of biochar reduced the pore size of modified biochar, whereas the surface area was enhanced.The obtained data of isotherm models were tested using different error function equations. The Freundlich,Tempkin and Langmuir isotherm models were best fitted to the experimental data of Melon-B, Melon-BO-NH_2 and Melon-BO-TETA, respectively. The adsorption rate was primarily controlled by pseudo-second–order rate model. Conclusively, the functional groups interactions are important for adsorption mechanisms and expected to control the adsorption process. The adsorption for the Melon-B, Melon-BO-NH_2 and Melon-BO-TETA could be explained for acid–base interaction and hydrogen bonding interaction.
