Excessive moisture transport into building enclosures can lead to increased energy use as well as mold growth and structural rot when moisture condenses in wall cavities. Currently, architects and builders must use passive membrane products as weather resistant barriers which exhibit a single permeability irrespective of environmental conditions. Membranes with a single high permeability may allow ...

A major source of volatile organic compound emissions into the environment is thevent stream from the glycol-based dehydration units used to remove water fromnatural gas. A glycol dehydration unit operating on a 50-million SCFD naturalgas stream will typically discharge more than 40 tons per year of varioushazardous volatile organic air pollutants - about half of which is "BTEX"(benzene, toluene, ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

Optical sensing for nuclear detonation detection involves space‐based detection within the visible wavelength. Emerging optical detectors will leverage unique diffractive optics to help enhance and discriminate signals of interest from other background emitters. Because of the precision required to achieve these objectives, innovative designs and manufacturing methods are required to benefit Nuc ...

Ethylene demand is expected to increase by 50% domestically and worldwide over the next 5 years with a scramble to increase supply via expansion or grass root facilities. US capacity will remain at about 20% of the world’s supply and exceed 100 BPPY. To meet this challenge, US-DOE has invented a mixed metal oxide catalyst, M1 for the oxidative dehydrogenation of ethane (C2-ODH) to ethylene at hi ...

Synchrotron-based science has had a great scientific impact and will continue to have great impact going forward. For high brightness 3rd and 4th generation light sources, errors are almost completely due to distortion in the front-end optics caused by the high heat loads generated by the broadband radiation from the insertion device. Diamond offers a solution because of its low x-ray absorption a ...

A new quasi-resonant converter, called the unipolar series resonant converter ("USRC"), will be adapted as a four-quadrant drive for electric vehicles ("EVs"). With zero current and voltage switching, it will high modulation frequency (over 30 khz), thus driving a motor silently and efficiently throughout the speed range. The USRC produces any waveform required by any type of EV motor. It produces ...

The high‐energy physics (HEP) community has identified integral field spectroscopy (IFS) as an area that could dramatically leverage investments in current and future sky surveys for the study of dark energy. Many lines of evidence now agree that most mass in the universe is in the form of dark matter, which interacts mainly via the force of gravity. Identification and detailed phenomenology of ...

A fundamental component responsible for low bit error rate (BER) is the phase jitter of the frequency reference source, regardless if a network is wireless or fiber optic in nature. In the case of wireless the frequency reference source is typically a voltage controlled oscillator (VCO), and in the fiber optic case it is a clock. In order to maximize the full benefit of spread spectrum technique ...
