Chemistry and engineering of the production process: State of the art

The present paper discusses the evolution of the chemistry and engineering of the production process of cement since the last (12th) International Congress on the Chemistry of Cement held at Montreal in 2007 Beaudoin (2007).In the last decade, the developed areas have addressed mainly the concrete design and its utilisation Young (2008). They are not treated here.In addition to the concrete applications, significant trends of innovation in cement science concerning the chemistry and engineering of the production process are observed.These trends are the consequence of the commitment of the cement industry towards the environmental constraints, the compliance with economic needs and the evolution of the market.Based on analytical studies, it seems that the cement industry will have a sustainable future if, first of all, the rate of innovation becomes higher than the rate of the occurrence of constraints and if the cement industry is able to anticipate these constraints.

Development of Fibrates as Important Scaffolds in Medicinal Chemistry

Fibrates are a class of phenoxyisobutyric acid derivatives mainly used as anti-hyperlipidemic agents. The fibrate scaffold has undergone a variety of chemical modifications, providing a wide spectrum of biological activities. Within the last few years, the majority of new synthetic fibrate derivatives have demonstrated hypolipidemic activity through peroxisome proliferator-activated receptor α (PPARα) activation. However, some compounds containing the fibrate scaffold have shown different pharmacological properties, also independent of PPARα activation, such as anti-inflammatory, analgesic, antioxidant, and antiplatelet activities. The aim of this review is to highlight the structure–activity relationships (SAR) in evaluating the significance of fibrates in the field of medicinal chemistry.     

Photoresponsive Metal-Organic Frameworks as Adjustable Scaffolds in Reticular Chemistry

The easy and remote switching of light makes this stimulus an ideal candidate for a large number of applications, among which the preparation of photoresponsive materials stands out. The interest of several scientists in this area in order to achieve improved functionalities has increase parallel to the growth of the structural complexity of these materials. Thus, metal-organic frameworks (MOFs) turned out to be ideal scaffolds for light-responsive ligands. This review is focused on the integration of photoresponsive organic ligands inside MOF crystalline arrays to prepare enhanced functional materials. Besides the summary of the preparation, properties and applications of these materials, an overview of the future outlook of this research area is provided.     

Supramolecular Chemistry in Solid State Materials such as Metal-Organic Frameworks

Supramolecular chemistry has enriched the scientific research for more than fifty years reaching one of its summits in 2016, when the Chemistry Nobel Prize was awarded for the design and synthesis of molecular machines, in which host-guest chemistry plays a fundamental role. Recently, the groups of Omar Yaghi and Fraser Stoddart, among others, have demonstrated that this chemistry can be extended to the pores of metal-organic frameworks (MOFs). This heterogenization of supramolecular chemistry can be achieved through the incorporation of macrocycles to the organic struts of these highly porous and crystalline materials. Throughout this short review we summarize interesting examples of selective recognition by naturally occurring and synthetic macrocycles in solution and solid state; and later we survey important milestones to achieve specific recognition sites and develop host-guest chemistry at the pores of MOFs. This summary contains examples of different synthetic strategies to incorporate macrocycles to solid state materials, and in particular, to prepare supramolecular MOFs with particular properties and related applications. Specifically, the revised research includes the incorporation of both naturally occurring and synthetic macrocycles to solid state materials such as polymers, metal nanoparticles, etc., as prelude of the solid phase recognition studied in MOFs. An important number of the contributions presented here feature porous solids with smooth access to the host's cavity incorporated in the pores, allowing specific recognition of guest molecules. This smooth access to those active recognition sites in materials with extremely high surface area such as MOFs, open the possibility to develop the next generation of frontier materials with application in fields such as selective capture of water toxins and heterogeneous catalysis, among others.     

论构成艺术与陶艺

一、现代陶艺之概念 中国向来以“瓷国”著称,具有悠久的陶瓷文化底蕴,对全世界的陶瓷艺术发展做出过杰出的贡献。但正是由于这种极为深厚的历史底蕴和根植于国人心中的陶瓷审美模式拖延了中国现代陶艺的萌芽,忽略了世界范围内新兴的现代陶艺审美观念,而一些西方国家,如英美和日本早在上世纪二三十年代便开始了近现代陶艺的起步和不断发展。

论构成艺术与现代陶艺创作观

自然界的物质结构及其生物、生理所构成的美的规律，显示出了巨大的生命力和感染力。同样，艺术中关的形式，有美的法则，也和其它事物的发展一样，逐渐形成了自己的规律性，找到了美的规律、美的法则。然而，任何视觉艺术的形式美规律，都是美的一种表现形态，它必须通过一定的组织结构和艺术语言体现出来。这种形式美规律包含着秩序与和谐、节奏与韵律、条理与反复、比例与尺度、空间与分割、对称与平衡、动与静等。而构成主义艺术就是充分聚集了这些形式美规律应用在其组织结构和艺术语言中。
