Sustainable Concrete: Enhancements and Challenges

Assi L., Carter K., Deaver E., Dekhn H., Ziehl P., University of South Carolina, US

Fly ash-based geopolymer concrete or alkali-activated fly ash-based concrete is a sustainable concrete that is not only reduced CO2 emissions, and also it utilizes waste materials such as fly ash, metakaolin, or blast furnace slag. [...]

Utilization of Aerogel Materials and Systems in the Building Envelopes of Tomorrow

Jelle B.P., Gao T., Norwegian University of Science and Technology (NTNU) / SINTEF Building and Infrastructure, NO

Building envelopes incorporating aerogel materials may exploit miscellaneous properties of the aerogels such as a very low thermal conductivity, lightweight properties due the air-filled low-density aerogel structure, and the possibility of utilizing solar radiation as [...]

Pilot Scale Demonstration & Independent Verification of Carbon Utilization Technologies for the NRG COSIA Carbon XPRIZE

Hansen T., Woolcock P., Leitch M., Extavour M., McCabe K., Southern Research, US

The NRG COSIA Carbon XPRIZE is a global competition to develop technologies for converting CO2 from power plants and industrial facilities into valuable products. The pilot scale demonstration required teams to operate at a 200 [...]

MCM-41 and Functionalized MCM-41 as Adsorbents to Remove Heavy Metals and Hardness from Contaminated Water and Groundwater

Leung S.W., Basnet N., Dejesus K., Lai J.C.K., Idaho State University, US

Mining operating and abandoned mines often have resulted in waste rock dumps and open pits that contain materials high in heavy metals and toxic elements. These contaminants are known to be present in groundwater, surface [...]

A Novel, Nanostructured, Metal-Organic Frameworks-Based Pretreatment Technology for the Remediation of PFAS in Industrial Wastewater

Ozdemir O.K., Ornstein J.M., framergy, Inc, US

Per-and polyflouralkyl substances, otherwise known as PFAS, are a class of chemicals that include perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). This class of chemcials has a large variety of uses globally, but their utilization [...]

The Use of Focused Aerosol Deposition in the Collection and Analysis of Nanoparticles from Ultrapure Water Systems Used in Semiconductor and Pharmaceutical Industry

Van Schooneveld G., Keady P., Oberreit D., CT Associates, Inc, US

The reduction of particles in ultrapure water (UPW) systems is driven primarily by the semiconductor industry. Particles that can produce defects in chip manufacturing and potentially reduce yield, are now identified to be 10 nm [...]

Mechanical Re-Design of a Wells Turbine Blade to improve the efficiency of the LIMPET Wave Energy Conversion System

Montes A., Centro de Enseñanza Técnica y Superior, MX

Renewable energies are told to be the future of energy generation for the world; nowadays, the wind sector is the one with more development in technology. However, there are two big sources of energy that [...]

Photocatalytic Activity of Immobilized Nano-TiO2 in Complex Wastewaters: Case Study of Multiple Dye Composition

Bellè U., De Flaviis L., Diamanti M.V., Ormellese M., Pedeferri M., Politecnico di Milano, IT

Titanium dioxide (TiO2) is widely investigated for its photocatalytic properties and for the possibility of obtaining nanotubular oxide films with high specific surface area directly immobilized on a substrate. In the present work, nanotubular TiO2 [...]

Characterization of the Oils of some Non-Edible Seeds as Biodiesel

Osadolor O.O., Clifford O.O., Ambrose Alli University, Ekpoma, Nigeria, NG

In this study, oils of the seeds of Azadirachta indica(Neem), Mangnifera indica(Mango), Thevetia peruviana, Jatropha curcas and Hervia Brasilensis(Rubber) were extracted and transesterified. The oil and biodiesel yields were; Neem, 97%, Mango, 90%, Thevetia 98%, [...]

BTMO Catalyzed Hydrothermal Liquefaction of Lignocellulosic Biomass
