This article presents a study in which new materials are developed through experimental knowledge construction and knowledge exchange between different disciplines. The New Silk research project (2017-2020) is the building block for the research. New Silk aims to produce new types of silk-like materials in the context of synthetic biology. In this article we discuss the initial experimental touchpoints between material science, synthetic biology, design and art encountered during the project’s first year. Firstly, the study shows that shared material experiences in the setting of workshops build foundational understanding of perceived material agency leading to discussion on material activity and research ethics. Secondly, our research identified that all of these disciplines, material science, synthetic biology, design and art, approach materials research through experimental methods, even if the goal of the research differs in each discipline.

The One of alternative energy that is environmentally friendly is by untilize water energy and turn it into a Microhydro power plant. Microhydro power plant usually made from utilize the waterfall with the head fell. While utilization for streams with a head small drop is not optimal yet. This is a reference to doing research on harnessing the flow of a river that has a value of head low between 0.7 m – 1.4 m with turning it into a Vortex flow (vortex). The purpose of this research is to know  the effect variation number of blade on power and efficiency in the vortex turbine. This research uses experimental methods to find current, voltage, torque and rpm using a reading instrument. The materials research vortex turbine used 6 blade, 8 blade and 10 blade with flat plate. The result showed the highest efficiency is 29,93 % with produce turbine power is 19,58 W, generated on turbine with variation 10 blade with load 3,315 kg and the capacity of water 10,14 l/s. Followed with an efficiency 24,17% and produce turbine power is 15,81 W, generated on turbine with the variation 8 blade with load 3,315 kg and the capacity of water is 10,14 l/s. The the lowest turbine efficiency 22,32% with produce tuebine power 14,60 W, generated on turbine with the variation 6 blade with load 3,315 kg, the capacity of water is 10,14 l/s.

<p>The analysis presented in this manuscript helps bridge an important fundamental discrepancy between the existing theoretical and experimental knowledge regarding the performance of Ag catalysts for CO<sub>2</sub> electrochemical reduction (CO<sub>2</sub>ER). The results demonstrate how the intermediate species *OCHO is formed readily en-route the HCOO<sup>– </sup>pathway and plays a decisive role in determining selectivity of a predominantly CO producing catalyst such as Ag. Our theoretical and experimental approach develops a better understanding of the nature of competition as well as the complex interactions between the reaction intermediates leading to CO, HCOO<sup>–</sup> and H<sub>2</sub> during CO<sub>2</sub>ER.</p><p><br></p><p>Details of computational and experimental methods are present in the Supporting Information provided. </p><p><br></p><p><br></p>

AbstractThroughout human history, most further developments or new achievements were accompanied by new materials or new processes that enabled the technologic progress. With concrete devices and applications in mind, synthesis and subsequent treatment of materials naturally went along with the progress. The aim of the underlying article is to spot the role of optimization, of discovery, of trial-and-error approaches, of fundamentals and curiosity driven design and development. In a consecutive examination, five missions addressing the challenges facing our world (identified by the European Council) will be cross linked with seven topical areas from materials science defined by the European Materials Research Society. The scope of this examination is to identify approaches and methods to further develop and innovate materials which form the basis of the anticipated solutions.

Blast Effect

Building protection on our century is very important because of the terrorist attacks. The old buildings in Europe aren’t enough strong again blast loads. Nowadays we know many different explosives and theirs effects of walls and human bodies. The detonation caused blast effect provokes building damage and fragmentation effects. The explosion caused damages, parts of bricks and fragments produce other secondary damage in other buildings and human bodies.It can’t protect the historical and old buildings by new walls and fences because of the cityscape. It needs to find new possibilities to improve the buildings resistance again blast effects. It needs a effectively thin and strong materials to reinforced the buildings walls. The new materials innovated by material science can be good solution for this project. These materials usually composites likes syntactic foams, spherical shells or carbon fields reinforced composites.

In this chapter, we will present a review of theoretical and empirical analyses of Web-based collaboration processes used during a scripted university course. The results refer to a design-based study that involved first-year teacher-education students (N = 30) studying pedagogy over a period of three months. The intervention involved structuring the subjects’ collaborative actions with three different pedagogical scripts. According to the findings, the scripts guided students’ activities by helping them find resources for knowledge construction and work together through a series of steps. However, there were variations among groups in terms of quality of collaboration, and the students mostly cumulatively shared or constructed knowledge from similar perspectives. On the basis of the challenges raised in the SCORE and related studies, future prospects are outlined for the design of flexible pedagogical scripts.

In order to introduce students to mechanical engineering, a first year design laboratory was developed based on pine wood derbies that are run in various children’s organizations. In these races, children and their parents design and build a car using a kit consisting of a pine block, metal axles and plastic wheels. This design exercise introduces students to several aspects of mechanical engineering, including manufacturing, aerodynamics, and material science. It also builds on courses that cover engineering drawing and report writing.

This study uses Critical Discourse Analysis and Social Network Analysis to examine an online peer mentoring site created to unite first-year and third-year preservice teachers enrolled in an undergraduate teacher education program. The peer mentoring site was developed to provide both first-year preservice teachers and more experienced peers the opportunity to discuss, share, and learn both from and with one another. The study demonstrated that the online peer mentoring site supported valuable interactions and professional communications among first-year and third-year students. In particular, the preservice teachers engaged with one another to share their experiences and learning as they prepared to be teachers. This study has implications for the field of undergraduate education in its demonstration that an online peer mentoring site can allow for the cultivation of learning, ideas and knowledge exchange, and support of students learning in informal environments. This research also has implications for future research to determine how different populations of students use an online peer mentoring site to interact with their peers and the outcomes that emerge. Such data could inform future development of peer mentoring sites and similar learning spaces.
