Shared Manufacturing is a new mode of social manufacturing based on the principles sharing economy. This paper presents scalable framework for blockchain-based that preserves transparency and immutability characteristics transaction records, which critical to building trust between entities in systems. We define protocol service execution according design present integration blockchain technology into concept by employing cross-chain solutions. discuss existing cross chain technologies...

This paper presents an approach to integrating Blockchain and IoT technologies into modern supply chains. We propose the concept of a new logistics platform that is built as distributed network nodes offers alternative dealing with complexity chains by breaking them smaller, functionally independent parts. The modular structure allows users add their own or extend functionality existing ones. Nodes are communicating use technology, which serves bridge between virtual real worlds, making this...

Pure and copper-modified photocatalytic TiO2 nanopowders were prepared via a green sol–gel route heated to 450 °C. Copper does not enter the lattice but forms as smaller ∼2 nm Cu-based nanocrystals, decorating surface of ∼10 nanoparticles. The larger nanoparticles (NPs) is partially covered by much Cu NPs, attached NPs completely covering them due small quantity present (1–10 mol % Cu). This retards anatase-to-rutile phase transition titania domain growth through grain-boundary pinning...

Today, globalized markets require more resilient and agile manufacturing systems, as well customized virtualized features. Classical self-standing systems are evolving into collaborative networks such Cloud Manufacturing (based on centralized knowledge distributed resources) or Shared fully decentralized a solution to ensure business continuity under normal special circumstances. Additive (AM), one of the enablers Industry 4.0 (I4.0), is promising technology for innovative production models...

In order to expand the use of titania indoor as well increase its overall performance, narrowing band gap is one possibilities achieve this. Modifying with rare earths (REs) has been relatively unexplored, especially modification rutile earth cations. The aim this study was find influence TiO₂ on structural, optical, morphological, and photocatalytic properties. Titania synthesized using TiOSO₄ source titanium via hydrothermal synthesis procedure at low temperature (200 °C) modified selected...

This study investigates the effects of blockchain technology scalability limitations on performance Blockchain-Based Shared Manufacturing (BBSM), an innovative smart-manufacturing paradigm aimed at enhancing utilization global manufacturing resources via peer-to-peer (P2P) collaboration self-organized assets. Despite prevalence research highlighting technology’s as main barrier for adoption, few studies have explored their operation blockchain-based systems. The primary goal presented work...

The influence of the reaction conditions during transformation hydrogen titanate nanoribbons to TiO2 on phase composition, morphology, appearance nanoribbon surfaces and their optical properties was investigated. transformations were performed (i) through a heat treatment in oxidative reductive atmospheres temperature range 400-650 °C, (ii) hydrothermal neutral basic environments at 160 (iii) microwave-assisted environment 200 °C. Scanning electron microscopy investigations showed that...

Researchers in the field of smart manufacturing have recognized benefits blockchain technology, which solves trust problem open network without relying on any trusted third party. Blockchain technology enables interaction between otherwise competing entities to satisfy increasing customer demands a trustful way. However, existing networks are facing limitations, defined by trade-off scalability, decentralization, and security. The scalability is as ability support an load transactions it...

Recently, smart-parking systems were proposed employing blockchain technology to ensure security, transparency, and availability of services. Building on a principle complete system decentralization, we present the concept implementation privacy-preserving solution for renting parking spaces. The anonymity users is ensured by combination zero knowledge proofs, commitment schemes, differential privacy fungible tokens. We compare implementations three different public networks: Ethereum, EOS,...

Titanium dioxide is by far the most utilised semiconductor material for photocatalytic applications. Still, it transparent to visible-light. Recently, has been proved that a type-II band alignment rutile−anatase mixture would improve its visible-light absorption.In this research paper we thoroughly characterised real crystalline and amorphous phases of synthesised titanias – thermally treated at different temperatures get distinct ratios anatase-rutile-amorphous fraction as well three...

In this paper an outline of the Erasmus+ program is given. Cooperation among organizations and institutions (Key Action 2 Programme) described in a little more detail, because TET project part initiative. The motivation for presented first as key component when needs analysis must be done proposal. This followed by description partnership planned implementation.

The development of smart manufacturing modes, following the guidelines Industry 4.0 paradigm, suggests use new technologies to ensure greater agility, individualization and personalization. Blockchain technology, as one technologies, enables decentralization trustless environment, however, on other hand, introduces scalability limitations into system. This paper presents an exploratory network analysis money flow in blockchain-based Shared Manufacturing. We conduct experiment form online...

Outdoor and indoor air pollution is a global environmental concern in modern society. Although many policies regulations on quality have been promulgated worldwide over the past decades, airborne still negatively affects health therefore life-style of human beings. One strategies to challenge this problem might be reducing amount pollutant by mineralising them via photoinduced reactions. Photocatalytic oxidation gaseous pollutants titanium dioxide one most investigated solar photochemical In...
