Magnetic scattering of spin polarized carriers in (In, Mn)Sb dilute magnetic semiconductor.

Physical review letters

Csontos M, Wojtowicz T, Liu X, Dobrowolska M, Jankó B, Furdyna JK, Mihály G.
PMID: 16384260
Phys Rev Lett. 2005 Nov 25;95(22):227203. doi: 10.1103/PhysRevLett.95.227203. Epub 2005 Nov 21.

Magnetoresistance measurements on the magnetic semiconductor (In, Mn)Sb suggest that magnetic scattering in this material is dominated by isolated Mn2+ ions located outside the ferromagnetically ordered regions when the system is below T(c). A model is proposed, based on...

Background. The purpose of this article is to present treatment outcomes for dysplastic hips in cerebral palsy, operated by tenotomy of the thigh adductor muscles and the greater iliopsoas muscle. Material and methods. 40 dysplastic hips in 20 severely...

Spin-polarizable excitonic luminescence in colloidal Mn2+-doped CdSe quantum dots.

Nano letters

Beaulac R, Archer PI, Liu X, Lee S, Salley GM, Dobrowolska M, Furdyna JK, Gamelin DR.
PMID: 18331001
Nano Lett. 2008 Apr;8(4):1197-201. doi: 10.1021/nl080195p. Epub 2008 Mar 11.

The photoluminescence of colloidal Mn2+-doped CdSe nanocrystals has been studied as a function of nanocrystal diameter. These nanocrystals are shown to be unique among colloidal doped semiconductor nanocrystals reported to date in that quantum confinement allows tuning of the...

Ar-matrix IR spectra of 5-halouracils interpreted by means of DFT calculations.

The journal of physical chemistry. A

Dobrowolski JC, Rode JE, Kołos R, Jamróz MH, Bajdor K, Mazurek AP.
PMID: 16838988
J Phys Chem A. 2005 Mar 17;109(10):2167-82. doi: 10.1021/jp045213f.

The infrared low-temperature Ar-matrix spectra of 5-halouracils and unsubstituted uracil were measured and interpreted in terms of the spectra calculated at the DFT/B3PW91/6-311G level followed by a potential energy distribution (PED) analysis. For the PED analysis, the sets of...

High-rate automated deposition system for the manufacture of complex multilayer coatings.

Applied optics

Sullivan BT, Clarke GA, Akiyama T, Osborne N, Ranger M, Dobrowolski JA, Howe L, Matsumoto A, Song Y, Kikuchi K.
PMID: 18337884
Appl Opt. 2000 Jan 01;39(1):157-67. doi: 10.1364/ao.39.000157.

A previously described automated thin-film deposition system based on rf-magnetron sputtering could deposit quite complex optical multilayer systems with good precision and with no one in attendance [Sullivan and Dobrowolski, Appl. Opt. 32, 2351-2360 (1993)]. However, the deposition rate...

Three Clonal Lineages of Phytophthora cinnamomi in Australia Revealed by Microsatellites.

Phytopathology

Dobrowolski MP, Tommerup IC, Shearer BL, O'Brien PA.
PMID: 18943056
Phytopathology. 2003 Jun;93(6):695-704. doi: 10.1094/PHYTO.2003.93.6.695.

ABSTRACT The genetic structure of populations of Phytophthora cinnamomi, a pathogen of an enormous variety of woody plants, was investigated using microsatellites. Three intensively sampled disease sites in southwest Australia were analyzed along with a large culture collection of...

Toward perfect antireflection coatings. 3. Experimental results obtained with the use of Reststrahlen materials.

Applied optics

Dobrowolski JA, Guo Y, Tiwald T, Ma P, Poitras D.
PMID: 16539263
Appl Opt. 2006 Mar 01;45(7):1555-62. doi: 10.1364/ao.45.001555.

The equipment and methods used to produce wide-angle antireflection coatings based on Reststrahlen materials are described. The optical constants of the coating materials used in the construction of the multilayers were determined by spectrophotometric ellipsometry and are compared with...

Research on thin film anticounterfeiting coatings at the National Research Council of Canada.

PMID: 20555586
Appl Opt. 1989 Jul 15;28(14):2702-17. doi: 10.1364/AO.28.002702.

After a brief description of the threats which face the issuers of documents and valuable papers, the concept of thin film anticounterfeiting coatings proposed by the NRCC is explained. The colorimetric considerations which govern the design of such devices...

Synthesis of high rejection filters with the Fourier transform method.

Applied optics

Verly PG, Dobrowolski JA, Wild WJ, Burton RL.
PMID: 20555614
Appl Opt. 1989 Jul 15;28(14):2864-75. doi: 10.1364/AO.28.002864.

Although in theory the Fourier transform method is valid only for small rejections, in practice it can be modified for the synthesis of high rejection filters with minimum transmittances as low as 10(-4). Two new spectral functions are proposed...

The program for the synthesis of nonabsorbing thin film systems by the method of gradual evolution [J. A. Dobrowolski, Appl. Opt. 4, 937 (1965)] has been extended to include new features and to handle absorbing materials. In the analysis...

Computation speeds of different optical thin-film synthesis methods.

Applied optics

Li L, Dobrowolski JA.
PMID: 20725355
Appl Opt. 1992 Jul 01;31(19):3790-9. doi: 10.1364/AO.31.003790.

Several different thin-film design problems were solved by the comprehensive-search, gradual-evolution, minus-filter, flip-flop, and inverse-Fourier-transform, thin-film synthesis methods. In order to compare the relative effectiveness of each method, the results obtained and computation times required by these techniques for...
