Author: Ghazi-Tehrani, Adam Kavon; Pontell, Henry N. Description: Phishing, the fraudulent attempt to obtain sensitive information by disguising oneself as a trustworthy entity via electronic communication, has quickly evolved beyond low-skill schemes that relied on casting “a wide net.” Spear phishing attacks target a particular high-value individual utilizing sophisticated techniques. This study aims to describe the current state of phishing, the expected technological advances and developments of the near future, and the best prevention and enforcement strategies. Data comes from interviews with approximately 60 information technology security professionals, “hackers,” and…

Author: Fillet, R.; Nicolas, V.; Fierro, V.; Celzard, A. Description: One way to harvest solar energy is to produce steam from liquid water. Steam can be used to provide freshwater even in a harsh environment, with extreme temperature and low groundwater supplies. It can also be extracted from polluted soil or water, purifying the water in the process at the same time. Water evaporation systems are energy effective, with efficiencies ranging from 60% to over 90%. Furthermore, they can be cost-effective and have a low environmental impact, using the right…

Author: Gong, Feng; Wang, Wenbin; Li, Hao; Xia, Dawei (David); Dai, Qingwen; Wu, Xinlin; Wang, Mingzhou; Li, Jian; Papavassiliou, Dimitrios V.; Xiao, Rui Description: Utilizing the clean and renewable solar energy to generate steam for wastewater purification or seawater desalination is a promising solution to the worldwide scarcity of fresh water. Herein, we report a highly-efficient, eco-friendly and cost-effective solar steam generator based on ball-milling graphite and cellulose fiber from waste paper. Ball-milling graphite/cellulose fiber composite aerogels are facilely developed via a freeze casting-drying method, endowing a featured vertically aligned…

Author: Zang, Kunpeng; Zhang, Gen; Wang, Juying Description: Although oil and gas explorations contribute to atmospheric methane (CH4) emissions, their impact and influence along the shelf seas of China remain poorly understood. From 2012 to 2017, we conducted four ship-based surveys of CH4 in the seawater column and boundary layer of the Bohai Sea, China, and further measured CO2 and several meteorological parameters. The average observed CH4 mixing ratios in the boundary layer and its concentrations in seawater column were 1950 ± 46 ppb in November 2012 (dissolved CH4 was…

Author: Punzo, E.; Gomiero, A.; Tassetti, A. N.; Strafella, P.; Santelli, A.; Salvalaggio, V.; Spagnolo, A.; Scarcella, G.; De Biasi, A. M.; Kozinkova, L.; Fabi, G. Description: Multidisciplinary monitoring of the impact of offshore gas platforms on northern and central Adriatic marine ecosystems has been conducted since 1998. Beginning in 2006, 4-5 year investigations spanning the period before, during, and after rig installation have explored the effects of its construction and presence on macrozoobenthic communities, sediment, water quality, pollutant bioaccumulation, and fish assemblages. In this study, sediment samples collected at…

Author: Gorchov Negron, Alan M.; Kort, Eric A.; Conley, Stephen A.; Smith, Mackenzie L. Description: Methane (CH4) emissions from oil and gas activities are large and poorly quantified, with onshore studies showing systematic inventory underestimates. We present aircraft measurements of CH4 emissions from offshore oil and gas platforms collected over the U.S. Gulf of Mexico in January 2018. Flights sampled individual facilities as well as regions of 5-70 facilities. We combine facility-level samples, production data, and inventory estimates to generate an aerial measurement-based inventory of CH4 emissions for the U.S….
