Organosilicate Polymer E-Beam Resists with High Resolution, Sensitivity and Stability

February 28, 2013
Author(s)
Christopher Soles, Richard Kasica, Hae-Jeong Lee, Jae H. Sim, Sung-Il Lee, Ki-Bum Kim, Hyun-Mi Kim, Do Y. Yoon
Hydrogen silsesquioxane (HSQ) is an attractive electron-beam (e-beam) resist for sub-20 nm lithography due to its high resolution, excellent line-edge-roughness (LER), and good plasma etch resistance. However, the sensitivity and long-term stability of HSQ

To Predict Vibrational Spectra, Are Anharmonic Calculations Worthwhile?

January 22, 2013
Author(s)
Ruth L. Jacobsen, Karl K. Irikura, Russell D. Johnson III, Raghu N. Kacker
Anharmonic calculations using vibrational perturbation theory are known to provide near-spectroscopic accuracy when combined with high-level ab initio potential energy functions. However, performance with economical, popular electronic structure methods is

A Humidity Generator for Temperatures to 200 degC and Pressures to 1.6 MPa

D Vega-Maza, W. Wyatt Miller, Dean C. Ripple, Gregory E. Scace
We have constructed a new humidity generator that produces gas streams of known moisture content at temperatures from 85 °C to 200 °C, absolute pressures from 0.2 MPa to 1.6 MPa, and relative humidities from 10 % to 90 %. The generator produces a moist gas

Absolute line intensities for ethylene from 1800 to 2350 cm-1.

November 17, 2012

Walter J. Lafferty, Jean-Marie Flaud, A. Ben Hassen, F. K. Kwabia Tchana, X Landsheere, H Aroui
Fourteen Fourier transform spectra of ethylene (C2H4) have been recorded in the 1800-2350 spectral domain with different path-lengths and pressures and used to derive individual line intensities for lines belonging to the ν7 + ν8, ν4 + ν8 , ν6 + ν10, ν6 +

Biosynthesis of Athmu, a alpha,gamma-hydroxy-ss-amino acid of pahayokolides A-B

October 2, 2012
Author(s)
Li Liu, Dan Bearden, Juan C. Rodriguez, Kathleen S. Rein
Pahayokolides A-B are cyanobacteria derived non-ribosomal peptides which exhibit cytotoxicity against a number of cancer cell lines. The biosynthetic origin of the 3-amino-2,5,7,8- tetrahydroxy-10-methylundecanoic acid (Athmu) moiety has been investigated

Recommended vapor pressure and thermophysical data for ferrocene

August 14, 2012
Author(s)
Michal Fulem, Kvetoslav Ruzicka, Marisa A. Rocha, Luis M.N.B.F. Santos, Robert F. Berg
Recommended vapor pressure data for ferrocene (CAS Registry Number: 102-54-5) in the temperature range from 242 to 447 K were developed by the simultaneous correlation of critically assessed vapor pressures, heat capacities of the crystalline phase and the

Ionic Liquid Facilitated Introduction of Functional Materials into Biopolymer Polymer Substrates

August 2, 2012
Author(s)
Shonali Nazare, Jeffrey W. Gilman, Mauro Zammarano, Luke Haverhals, W.Matthew Reichert, Hugh De Long, Paul C. Trulove
In addition to being efficient solvents for biopolymers, several ionic liquids (ILs) have been shown to be effective solvents for synthetic polymers such as meta-aramids, i.e., Nomex ® (1-5). In this report, meta-aramid/cotton composites are generated by
