1. High-temperature corrosion properties of chromia- and alumina-forming alloys
Abstract : Electricity production, transportation, and manufacturing industry are some of the largest sources of greenhouse gas emissions. In many cases, these processes are carried out at high temperature and energy efficiency is limited by material degradation, so-called ‘high-temperature corrosion’. READ MORE

2. Grouting of Fractured Rock with Silica Sol; Grouting design based on penetration length
Abstract : ABSTRACTRecent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is cement-based. During the past 10 years, the acceptable flow of water into tunnels has been reduced significantly. The current requirements mean that an average fracture aperture of around 0. READ MORE

3. Grouting of Hard Rock with Gelling Liquids, Field and Laboratory Studies of Silica sol
Abstract : Recent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is a cement-based one. During the past 10 years, the acceptable flow of water into tunnels has been significantly reduced. The current requirements mean that an average fracture aperture of around 0. READ MORE

4. Towards Energy-Efficient Drinking Water Production using Biomimicry
Abstract : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. READ MORE

5. Aqueous behaviour of characteristic molecules in the synthesis of porous silica materials : - an atomistic description
Abstract : The formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. READ MORE
