Flow and arrest in stressed granular materials

Flowing granular materials often abruptly arrest if not driven by sufficient applied stresses. Such abrupt cessation of motion can be economically expensive in industrial materials handling and processing, and is...

Structure Prediction and Mechanical Properties of Silicon Hexaboride on Ab Initio Level

Silicon borides represent very appealing industrial materials for research owing to their remarkable features, and, together with other boride and carbide-based materials, have very wide applications. Various Si–B phases have been investigated in the past, however a limited number of studies have been done on the pristine SiB6 compound. Structure prediction using a data mining ab initio approach has been performed in pure silicon hexaboride. Several novel structures, for which there are no previous experimental or theoretical data, have been discovered. Each of the structure candidates were locally optimized on the DFT level, employing the LDA-PZ and the GGA-PBE functional. Mechanical and elastic properties for each of the predicted and experimentally observed modifications have been investigated in great detail. In particular, the ductility/brittleness relationship, the character of the bonding, Young’s modulus E, bulk modulus B, and shear modulus K, including anisotropy, have been calculated and analyzed.

Using different waste as resilient layers for impact sound insulation improvement: New alternative to commercial layers?

In the residential building sector, the use of floating floors is a common practice which increasingly used to reduce vibrations and impact noise. These are usually made from industrial materials, although the emerging concern for sustainable construction is leading to the use of other materials from recycled waste. This article studies the performance of rubber, cork, and cigarette butts as a floating floor. For this purpose, their acoustic properties (ISO 9052-1 and 12,354-2 standards) are analyzed and compared with those of some commercial materials. The results obtained indicated that the performance of these eco-materials is equal or superior to that of commercially available materials.

Can earthen architectural heritage save us?

Contemporary architecture seems to turn its back on the past in terms of the raw materials taken from the environment, their transformation into building components and the way they are assembled to create buildings. The global challenge of preserving the environment forces us to rethink the way we produce architecture today. Within this challenge, the past shows us possible ways to fill the gap between tradition and modernity. However, we need to understand what motivates people to abandon ancestral materials and knowledge for materials that they cannot manufacture or use themselves. Is this transformation to industrial materials and forms irreversible? Is there nothing we can learn from our rich past? How can we revive endogenous knowledge to produce environmentally wise architecture? These are the questions that the authors, who have been working on the revival of earthen heritage for over 20 years, wish to answer.

Review of Element Analysis of Industrial Materials by In-Line Laser—Induced Breakdown Spectroscopy (LIBS)

Laser-induced breakdown spectroscopy (LIBS) is a rapidly developing technique for chemical materials analysis. LIBS is applied for fundamental investigations, e.g., the laser plasma matter interaction, for element, molecule, and isotope analysis, and for various technical applications, e.g., minimal destructive materials inspection, the monitoring of production processes, and remote analysis of materials in hostile environment. In this review, we focus on the element analysis of industrial materials and the in-line chemical sensing in industrial production. After a brief introduction we discuss the optical emission of chemical elements in laser-induced plasma and the capability of LIBS for multi-element detection. An overview of the various classes of industrial materials analyzed by LIBS is given. This includes so-called Technology materials that are essential for the functionality of modern high-tech devices (smartphones, computers, cars, etc.). The LIBS technique enables unique applications for rapid element analysis under harsh conditions where other techniques are not available. We present several examples of LIBS-based sensors that are applied in-line and at-line of industrial production processes.

A Sustainable Approach for the Refurbishment Process of Vernacular Heritage: The Sesga House Case Study (Valencia, Spain)

The refurbishment of traditional vernacular architecture is currently of interest for the conservation of heritage, historic landscape and cultural landscape, as well as for its potential benefits in the field of environmental sustainability. The carefully selected materials and techniques used in the refurbishment of a traditional dwelling in Sesga (Valencia, Spain) maintain the local construction techniques while causing the least possible environmental impact, saving on transport and transformation and construction energy. This article uses LCA to showcase this contribution, examining three scenarios: the first option is the refurbishment of the case study using natural traditional materials and techniques; the second presents a hypothetical refurbishment using widely used industrial materials; and a third option looks at the demolition of the existing building and the addition of a new construction with widely used industrial materials. This comparison has shown where and why the first option is, broadly speaking, the most sustainable option in environmental, sociocultural and socioeconomic terms.

Conceptual Designs for Sustainable Aesthetics: creative chess sets where form follows meaning

The paper presents conceptual designs that explore the notion of ‘sustainable aesthetics'. To encourage reflective practice through form and process, and guided by sustainable principles, a practice-based (thinking-and-doing) methodology was followed by Brazilian undergraduate design students. Beginning with a theoretical overview of the historical aesthetics of chess sets (premodern, modern and contemporary) the experimental findings show different approaches to thematic chess set designs that are guided by meaning-laden cultural considerations and developed using local, natural materials or reused (disposed) industrial materials. This is the first experiment of a project that represents a creative attempt to explore and develop an aesthetic for material culture through what we have termed a 'sustainable aesthetic function'. It demonstrates how objects with the same function can be expressed in very different ways whilst all adhering to the notion of "form follows meaning'.

Aplikasi Konsep Rekreatif pada Perencanaan Desain Budidaya dan Pengolahan Aren di Tuban

Palm tree (Arenga pinnata Merr.) is a multipurpose tree and it has been known that palm tree produces industrial materials.
