Nanocomposites based on three different shapes of nanoscale particles, sphere (silica), plate (clay), and tube (carbon nanotube), were prepared and the dispersion of the particles in the nanocomposites was confirmed by various techniques using TEM, SEM

A description of ionic transport in unsaturated porous materials due to gradients in the electro-chemical potential and the moisture content is developed by averaging the relevant microscopic transport equations over a representative volume element. The
CF3I has been considered to be a candidate replacement of CF3Br used in aircraft for fuel inerting and for fire fighting. In this study, the chemical effects of aircraft released CF3I on atmospheric ozone were examined with the current UIUC 2D Chemical
Previously, it has been suggested that in low water-to-cement ratio (w/c) concretes, the coarser cement particles could be replaced by an inert filer with little loss in performance in terms of hydration and strength development. This communication

This paper presents a discussion of standards requirements for LADAR. Two specific questions are addressed: (1) is there a need for such standards and (2) what types of standards are required? LADAR standards development issues and current standardization
Phase Doppler Anemometry (PDA) is a widely used measurement technique capable of non-intrusively measuring a droplet diameter and up to three components of its velocity, simultaneously. PDA systems are frequently used to characterize spray nozzles and

The current work is presented as part of an effort to develop a spray transport model that would be used within the computational fire code currently under development by Sandia National Laboratory. As part of a halon replacement research program, new high
This paper discusses the use of ultra-widehand radio signals near 5 GHz to detect moisture problems within building assemblies. Ultra-widehand signals are made up of a large spectrum of electromagnetic waves, and hardware is available to temporally resolve
The U.S. Environmental Protection Agency (EPA) Building Assessment Survey and Evaluation (BASE) study included a range of measurements in 100 randomly selected U.S. office buildings for the purpose of characterizing the existing building stock with respect

This research investigates the stability of iodotrifluoromethane (CF3I) during storage. For CF3I to be used as a fire extinguishing agent, it must be able to be stored for long periods of time at high pressure in metal containers without degrading and
