Efficient Computational Screening of Organic Polymer Photovoltaics.

The journal of physical chemistry letters

Kanal IY, Owens SG, Bechtel JS, Hutchison GR.
PMID: 26282968
J Phys Chem Lett. 2013 May 16;4(10):1613-23. doi: 10.1021/jz400215j. Epub 2013 Apr 29.

There has been increasing interest in rational, computationally driven design methods for materials, including organic photovoltaics (OPVs). Our approach focuses on a screening "pipeline", using a genetic algorithm for first stage screening and multiple filtering stages for further refinement....

Topological valley transport at bilayer graphene domain walls.

Nature

Ju L, Shi Z, Nair N, Lv Y, Jin C, Velasco J, Ojeda-Aristizabal C, Bechtel HA, Martin MC, Zettl A, Analytis J, Wang F.
PMID: 25901686
Nature. 2015 Apr 30;520(7549):650-5. doi: 10.1038/nature14364. Epub 2015 Apr 22.

Electron valley, a degree of freedom that is analogous to spin, can lead to novel topological phases in bilayer graphene. A tunable bandgap can be induced in bilayer graphene by an external electric field, and such gapped bilayer graphene...

Chemical composition of the giant red sea cucumber, Parastichopus californicus, commercially harvested in Alaska.

Food science & nutrition

Bechtel PJ, Oliveira AC, Demir N, Smiley S.
PMID: 24804015
Food Sci Nutr. 2013 Jan;1(1):63-73. doi: 10.1002/fsn3.12. Epub 2013 Jan 08.

Giant red sea cucumbers, Parastichopus californicus, are commercially harvested in the U.S. Pacific Northwest; however, the nutritional and chemical properties of its edible muscle bands and body wall have not been fully elucidated. In particular are the fatty acid...

Writing for publication in an RN to Baccalaureate program: an exercise in critical thinking.

Nursing and health care perspectives

Davidhizar R, Bechtel GA, Tiller CM.
PMID: 10640103
Nurs Health Care Perspect. 1999 May-Jun;20(3):146-50.

More than 35,700 registered nurses are currently enrolled in an RN to Baccalaureate completion program (I). The demand for these graduates is expected to continue, along with an increased demand for community-based educational programs. Many of these students have...

Triangulation research among culturally diverse populations.

Journal of allied health

Bechtel GA, Davidhizar R, Bunting S.
PMID: 10874331
J Allied Health. 2000;29(2):61-3.

There exists an ongoing challenge in the health sciences to develop research methods that effectively describe patterns of health beliefs and actions in different cultures. While the dominant framework for research has traditionally been the quantitative paradigm, qualitative methods...

Comparing the dynamical effects of symmetric and antisymmetric stretch excitation of methane in the Cl+CH4 reaction.

The Journal of chemical physics

Bechtel HA, Camden JP, Brown DJ, Zare RN.
PMID: 15267378
J Chem Phys. 2004 Mar 15;120(11):5096-103. doi: 10.1063/1.1647533.

The effects of two nearly isoenergetic C-H stretching motions on the gas-phase reaction of atomic chlorine with methane are examined. First, a 1:4:9 mixture of Cl(2), CH(4), and He is coexpanded into a vacuum chamber. Then, either the antisymmetric...

Millimeter-wave-detected, millimeter-wave optical polarization spectroscopy.

The Journal of chemical physics

Steeves AH, Bechtel HA, Coy SL, Field RW.
PMID: 16238366
J Chem Phys. 2005 Oct 08;123(14):141102. doi: 10.1063/1.2069865.

We report a new form of microwave optical double-resonance spectroscopy called millimeter-wave-detected, millimeter-wave optical polarization spectroscopy (mmOPS). In contrast to other forms of polarization spectroscopy, in which the polarization rotation of optical beams is detected, the mmOPS technique is...

Comparing reactions of H and Cl with C-H stretch-excited CHD3.

The Journal of chemical physics

Camden JP, Bechtel HA, Ankeny Brown DJ, Zare RN.
PMID: 16438587
J Chem Phys. 2006 Jan 21;124(3):034311. doi: 10.1063/1.2155434.

We report the methyl radical product state distributions for the reactions of H and Cl with CHD3(nu1 = 1,2) at collision energies of 1.53 and 0.18 eV, respectively. Both reactions demonstrate mode selectivity. The resulting state distributions from the...

Hydroxyl and its concentration profile in methane-air flames.

Applied optics

Bechtel JH, Teets RE.
PMID: 20216770
Appl Opt. 1979 Dec 15;18(24):4138-44. doi: 10.1364/AO.18.004138.

Hydroxyl concentration profiles are measured in several atmospheric-pressure premixed laminar flames. The first quantitative comparison of hydroxyl concentration profiles to recent flame models is presented. These models include the influence of hydroxyl on fuel breakdown, on carbon monoxide oxidation,...

Coherent anti-Stokes Raman spectra of oxygen atoms in flames.

Optics letters

Teets RE, Bechtel JH.
PMID: 19710736
Opt Lett. 1981 Oct 01;6(10):458-60. doi: 10.1364/ol.6.000458.

Coherent anti-Stokes Raman spectroscopy (CARS) was used to detect oxygen atoms (electronic Raman scattering) and oxygen molecules (rotational Raman scattering) in both hydrogen-oxygen and methane-oxygen flames. The high spectral resolution of CARS is useful for distinguishing the oxygen-atom signals...
