Surface Spectroscopy on UHV-Grown and Technological Ni–ZrO2 Reforming Catalysts: From UHV to Operando Conditions
Ni nanoparticles supported on ZrO2 are a prototypical system for reforming catalysis converting methane to synthesis gas. Herein, we examine this catalyst on a fundamental level using a 2-fold approach employing industrial-grade catalysts as well as surface science based model catalysts. In both cases we examine the atomic (HRTEM/XRD/LEED) and electronic (XPS) structure, as well as the adsorpti...
متن کاملWhat is Ethics of Science and Technology?
Background: The existence of crises and problems such as non-compliance with standards and professional ethics in the field of engineering and technology, and existence of fraud and misuse in the field of science has resulted in importance of ethics in the science and technology. But the fact is that there is no accurate understanding of the ethics of science and technology, and this field is o...

Financing is one of the essential necessitates for science and technology development that many universities have paid attention to it and through establishing financing funds including endowment funds have realized this important issue. So endowment today has played a crucial role in financing and the issue of endowment, benefactors and strategic position of benefactors and donors has been one...
متن کاملInducing single-molecule chemical reactions with a UHV-STM: a new dimension for nano-science and technology.
Atomic and molecular manipulations with the scanning tunnelling microscope (STM) lead to many fascinating advances during the last decade. Recent achievements in inducing all of the basic steps of a chemical reaction with the STM at a single-molecule level open up entirely new opportunities in chemistry on the nanoscale. In this article, we review various STM-based molecular manipulation techni...
متن کاملIntegration of Science and Technology in Primary Curriculum
One of the main issues to be considered in the educational system is education. Education is the result of four elements which are interacting with each other. These four elements are: teaching, learning, structure and curriculum. Curriculum is a plan for action which forms the structure. Another issue is the status of knowledge and the way we can transform it into educational materials. In pos...
