The purpose of this study is to make a review and or definition of AM (additive manufacturing), and an evaluation of its use in furniture production within a few projects to provide industry-specific awareness. AM can be considered as one of the latest innovative processes, as a state-of-the-art development, in manufacturing industries. AM is expressed as the future of the products and localization of the manufacturing processes in some studies. Innovation is a key factor both for firms and consumer products or service output. And, in today's competitive environment, it compels all the partners for R & D activities to provide technological development. But, all the partners come to a parting of the ways of disruptive or sustainable innovation. It can be said that furniture manufacturing by AM method is relatively new. Non-industrial use of the AM in furniture production can be stated as one of the latest innovative development. Thereby, this study reviews how AM is used to produce furniture within applied projects, which materials and methods are used for production and suggests its future impact. 展开更多

The aim of the study is to conduct comprehensive experiments and developments of innovative technologies to produce the oil extract of amaranth for their application as food additives in the food industry. To achieve the aim, the following tasks were identified: (I) study the physicochemical, biochemical properties and the composition of amaranth seeds; (2) improving the methods for producing the oil extract of amaranth. This article is devoted to complex research of processes of manufacture of vegetable oils. Authors have developed scientific bases of improvement and an intensification of technological processes for production of oil from amaranth seeds. The authors have developed a new technology for extracting of oil from amaranth seeds using hexane as a solvent. The proposed method provides to obtain oil without great technical effort and keeps it all the nutrients that promote the highest taste of the product and with little labor and time costs. 展开更多

We report the enhanced performance of organic solar cells(OSCs) based on regioregular poly(3-hexylthiophene)(P3HT) and methanofullerene [6,6]-phenyl C61-butyric acid methyl ester(PCBM) blend by using dihydroxybenzene ... We report the enhanced performance of organic solar cells(OSCs) based on regioregular poly(3-hexylthiophene)(P3HT) and methanofullerene [6,6]-phenyl C61-butyric acid methyl ester(PCBM) blend by using dihydroxybenzene as additive in the active layer.The effect of the content of the additives on electrical characteristics of the device is studied.The device with 0.2 wt% dihydroxybenzene additive achieves the best power conversion efficiency(PCE) of 4.58% with Jsc of 12.5 mA/cm2,Voc of 0.65 V,and FF of 66.6% under simulated solar illumination of AM 1.5G(100 mW/cm2),compared with the control device with PCE of 3.39%(35% improvement compared with the control device).The XRD measurement reveals that the addition of additives induces the crystallization of P3HT and establishes good inter-network to increase the contact area of donor and acceptor,and then helps charge to be effectively transferred to the electrode to reduce the chance of recombination.All evidences indicate that the dihydroxybenzene is likely to be a promising new type additive that can enhance the performance of organic bulk heterojunction solar cells. 展开更多
