Dual use of tantalum disulfides as hole and electron extraction layers in organic photovoltaic cells

28-10-2014 | Quyet Van Le; Thang Phan Nguyen; Kyoung Soon Choi; Yoon-Ho Cho; Young Joon Hong; Soo Young Kim, Physical Chemistry Chemical Physics, 2014

UV/ozone treated (UVO-treated) TaS2 and non-treated TaS2 nanosheets are introduced into organic photovoltaic cells (OPVs) as hole extraction layers (HEL) and electron extraction layers (EEL). TaS2 nanosheets are obtained via ultrasonic vibration and size-controlled by centrifugation. Atomic force ...

Bimolecular Recombination Reactions: K-Adiabatic and K-Active Forms of RRKM Theory, Nonstatistical Aspects, Low-Pressure Rates, and Time-Dependent Survival Probabilities with Application to Ozone. 2

22-10-2014 | Nima Ghaderi; R. A. Marcus, Journal of Physical Chemistry A, 2014

We consider for bimolecular recombination reactions the K-adiabatic versus the K-active forms of RRKM theory, where K is the component of the total angular momentum along the axis of least moment of inertia of the recombination product. When that product is approximately a prolate symmetric top, ...

Predicting the Effects of Nanoscale Cerium Additives in Diesel Fuel on Regional-Scale Air Quality

16-10-2014 | Garnet B. Erdakos; Prakash V. Bhave; George A. Pouliot; Heather Simon; Rohit Mathur, Environmental Science & Technology, 2014

Diesel vehicles are a major source of air pollutant emissions. Fuel additives containing nanoparticulate cerium (nCe) are currently being used in some diesel vehicles to improve fuel efficiency. These fuel additives also reduce fine particulate matter (PM2.5) emissions and alter the emissions of ...

Release of Nitrous Acid and Nitrogen Dioxide from Nitrate Photolysis in Acidic Aqueous Solutions

10-10-2014 | Nicole K. Scharko; Andrew E. Berke; Jonathan D. Raff, Environmental Science & Technology, 2014

Nitrate (NO3¯) is an abundant component of aerosols, boundary layer surface films, and surface water. Photolysis of NO3¯ leads to NO2 and HONO, both of which play important roles in tropospheric ozone and OH production. Field and laboratory studies suggest that NO3¯ photochemistry is a more ...

Reforestation as a novel abatement and compliance measure for ground-level ozone [Environmental Sciences]

07-10-2014 | Timm Kroeger; Francisco J. Escobedo; José L. Hernandez; Sebastián Varela; Sonia Delphin; Jonathan R. B. Fisher; Jani ..., Proceedings of the National Academy of Sciences current issue, 2014

High ambient ozone (O3) concentrations are a widespread and persistent problem globally. Although studies have documented the role of forests in removing O3 and one of its precursors, nitrogen dioxide (NO2), the cost effectiveness of using peri-urban reforestation for O3 abatement purposes has ...

Gas to Particle Conversion-Gas Exchange Technique for Direct Analysis of Metal Carbonyl Gas by Inductively Coupled Plasma Mass Spectrometry

06-10-2014 | Kohei Nishiguchi; Keisuke Utani; Detlef Gunther; Masaki Ohata, Analytical Chemistry, 2014

A novel gas to particle conversion-gas exchange technique for the direct analysis of metal carbonyl gas by inductively coupled plasma mass spectrometry (ICPMS) was proposed and demonstrated in the present study. The technique is based on a transfer of gas into particle, which can be directly ...

Surface graphitization of ozone‐treated detonation nanodiamonds

29-09-2014 | Jean‐Charles Arnault, Tristan Petit, Hugues A. Girard, Celine Gesset, Mathilde Combis‐Schlumberger, Mohammed Sennour ..., physica status solidi (a), 2014

Bifunctional detonation nanodiamonds (NDs) were obtained by vacuum annealing at 750 °C of NDs previously oxidized in ozone (ND‐ozone). Raman investigations demonstrate a significantly higher amount of sp2 carbon compared to ND with polyfunctional surface (ND‐NRI) annealed in vacuum under the ...

Practical realisation of ozone clearing after disperse dyeing of polyester

17-09-2014 | Seda Gundogan, Hüseyin Aksel Eren, Coloration Technology, 2014

In this study, a novel system utilising ozone in jet dyeing machines is introduced, and the results of ozone‐clearing treatments of disperse dyed polyester on the prototype modified machine are reported. A Venturi injector was mounted on the liquor circulation pipe of the jet dyeing machine to ...

Understanding Solvation in the Low Global Warming Hydrofluoroolefin HFO-1234ze Propellant

02-09-2014 | Lin Yang; Sandro R. P. da Rocha, Journal of Physical Chemistry B, 2014

Hydrofluoroolefins (HFOs), with zero ozone-depleting effect and very low global warming potential, are considered to be the next-generation high-pressure working fluids. They have industrial relevance in areas including refrigeration and medical aerosols. One major challenge expected in the ...
