Whitesides explains each photograph, describing why and how each of these phenomena occur."--BOOK JACKET
No small matter : science on the nanoscale by Felice Frankel ( Book )
7 editions published in 2009 in English and Undetermined and held by 766 WorldCat member libraries worldwide
A small revolution is remaking the world. The only problem is, we can't see it. Images and descriptions reveal the virtually invisible realities and possibilities of nanoscience. An introduction to the science and technology of small things. An overview of recent scientific advances that have given us our ever-shrinking microtechnology - for instance, an information processor connected by wires only 1,000 atoms wide. New methods are described that are used to study nanostructures, suggest ways of understanding their often bizarre behavior, and outline their uses in technology. The various means of making nanostructures are explained and speculated about their importance for critical developments in information processing, computation, biomedicine, and other areas. No Small Matter considers both the benefits and the risks of nano/microtechnology - from the potential of quantum computers and single-molecule genomic sequencers to the concerns about self-replicating nanosystems

Convergence of knowledge, technology and society : beyond convergence of nano-bio-info-cognitive technologies by Mihail C Roco ( Book )
1 edition published in 2013 in English and held by 8 WorldCat member libraries worldwide
Convergence of knowledge and technology for the benefit of society (CKTS) is the core opportunity for progress in the 21st century, based on five principles: (1) the interdependence of all components of nature and society, (2) enhancement of creativity and innovation through evolutionary processes of convergence that combine existing principles, and divergence that generates new ones, (3) decision analysis for research and development based on system-logic deduction, (4) higher-level cross-domain languages to generate new solutions and support transfer of new knowledge, and (5) vision-inspired basic research embodied in grand challenges. Solutions are outlined for key societal challenges, including creating new industries and jobs, improving lifelong wellness and human potential, achieving personalized and integrated healthcare and education, and securing a sustainable quality of life for all. This report provides a ten-year NBIC2 vision within a longer-term framework for converging technology and human progress that began with a previous study on NBIC fields: nanotechnology, biotechnology, information technology, and cognitive science (Roco and Bainbridge, 2003)
Attenuation Lengths of Photoelectrons in Hydrocarbon Films ( Book )
2 editions published in 1988 in English and held by 2 WorldCat member libraries worldwide
The attenuation length, lambda, of photoelectrons with energies in the range 900-1400 eV in hydrocarbon films was measured using self-assembled monolayers of alkanethiols, HSCnH2n+1, on gold. The intensity of the photoelectron peaks from the gold substrate decreased exponentially with the chain length, with attenuation lengths of 42 A at 1402 eV, 34 A at 1151 eV, and 28 A at 940 eV. Over the narrow energy range studied, lambda was directly proportional to the kinetic energy of the photoelectrons. Keywords: Photoelectron spectroscopy; Attenuation lengths; Monomolecular films; Self assembly; Gold; Alkanethiols. (jhd)

The Reactivity of Carboxylic Acid and Ester Groups in the Functionalized Interfacial Region of 'Polyethylene Carboxylic Acid' (PE-CO2H) and Derivatives: Differentiation of the Functional Groups into Shallow and Deep Subsets Based on a Comparison of Contact Angle and ATR-IR Measurements ( Book )
1 edition published in 1986 in English and held by 1 WorldCat member library worldwide
The carboxylic acid groups present in the functionalized interface of polyethylene carboxylic acid (PE-CO2H, a material prepared from low-density polyethylene film have been differentiated by reaction with aqueous chromic acid) into two subsets: those sufficiently close to the surface of the polymer to influence its wettability by water and those too deep to do so. This differentiation was accomplished by taking advantage of differences in rates of esterification of carboxylic acid groups in different regions of the functionalized interface, and of differences in rates of hydrolysis of ester groups derived from them. The subset of functional groups influencing wettability comprises <30% of the total groups present in the functionalized interface and appears to be homogeneous in its chemical reactivity. The remaining groups (approx. 70% of the total) do not directly influence wettability and appear to become less reactive with increasing depth in the polymer. The surface and subsurface carboxylic acid and ester moieties are both less reactive in hydrolysis and formation reactions than are these groups in organic molecules in solution. Reactivities of the interfacial functional groups depend on structure in ways having no analogy in reactions in solution
Designing Ordered Molecular Arrays in Two and Three Dimensions ( Book )
1 edition published in 1991 in English and held by 1 WorldCat member library worldwide
Two and three dimensional assemblies self-assembled monolayers (SAMs) and hydrogen-bonded co-crystals, respectively show substantial changes in their supramolecular structures with seemingly minor changes in the structure of their molecular atomic constituents. The structure of SAMs obtained by adsorption of alkanethiols onto silver and copper are indistinguishable, although the atomic radii of silver and copper are different. The structure of the SAM on silver is different from that on gold, although the atomic radii of these metals are essentially the same. A macroscopic property of the SAMs, wetting, is not affected by these structural differences. Co-crystals formed from derivatives of barbiturates and melamines form hydrogen bonded tapes in the solid state. These tapes provide a template for studying the packing forces within crystals
Reductive Elimination of H-H, H-CH3, and CH3-CH3 from Bis(Phosphine)Platinum(II), - Palladium(II), and -Nickel(II) Complexes: A Theoretical Study Using the SCF-X alpha-SW Method ( Book )
1 edition published in 1981 in English and held by 1 WorldCat member library worldwide
Self-consistent-field X alpha scattered-wave (SCF-Xalpha-SW) calculations have been carried out for two series of organometallic complexes (L = H3P: L2PtH2, L2Pt(H)CH3, and L2Pt(CH3)2; L2Ni(CH3)2, L2Pd(CH3)2, and L2Pt(CH3)2. These calculations suggest a correlation between the relative rates of reductive elimination (L2MXY yields L2M + XY) and the molecular orbital character of the starting complexes: those compounds which eliminate XY relatively rapidly have occupied molecular orbitals with pronounced M-X(Y) antibonding character those which eliminate XY slowly have only vacant M-X(Y) antibonding orbitals. No single orbital (HOMO or other) dominates the M-X(Y) bonding in thses complexes: bonding and antibonding character is distributed among several of the valence orbitals. We propose a simple model to correlate the occupancy of antibonding M-X(Y) orbitals and rates of reductive elimination with the relative electronegativities of M and X(Y). The limitations of this model, and alternates to it, are described briefly. (Author)
Wetting of Functionalized Polyethylene Film Having Ionizable Organic Acids and Bases at the Polymer-Water Interface: Relations between Functional Group Polarity, Extent of Ionization, and Contact Angle with Water ( Book )
1 edition published in 1988 in English and held by 1 WorldCat member library worldwide
This paper examines the wetting by water of low density polyethylene film modified at the polymer water (air) interface by introduction of polar organic functional groups (carboxylic acids, amines, and others). Water/polymer contact angles were determined for each of these interfaces; for interfaces containing acidic or basic functional groups, the contact angle was determined as a function of the pH. The observed contact angle was related to the hydrophilicity of these functional groups: as the hydrophilicity (as measured by Hansch pi parameters) increased up to a certain point, the contact angle decreased. Beyond that point, increased hydrophilicity had little additional influence on the contact angle. The result is interpreted in terms of water adsorbed on the polar interfacial functional groups: extensive hydration of interfacial groups having large negative pi parameters moderates their effective hydrophilicity.

Correlation between Surface Free Energy and Surface Constitution ( )
1 edition published in 1992 in English and held by 1 WorldCat member library worldwide
Self-assembled monolayers (SAMs) of alkylsiloxanes on elastomeric PDMS (polydimethylsiloxane) were used as model systems to study interactions between surfaces. Surface free energies of these chemically modified surfaces were estimated by measuring the deformations that resulted from the contact between small semispherical lenses and flat sheets of the elastomer under controlled loads. The measured surface free energies correlated with the surface chemical compositions of the SAMs and were commensurate with the values estimated from the measurements of contact angles. This study provides, for the first time, direct experimental evidence for the validity of estimates of the surface free energies of low-energy solids obtained from contact angles
X-Ray Damage to CF3CO2-Terminated Organic Monolayers on Si/Au Supports is due Primarily to X-Ray Induced Electrons ( Book )
1 edition published in 1991 in English and held by 1 WorldCat member library worldwide
X rays damage organic materials. The relative importance of X rays themselves, and of both X ray generated and secondary electrons, in this damage was explored using self-assembled monolayers (SAMs) on multilayer thin film supports. The substrates were prepared by depositing thin films of Si (0, 50, 100 and 200) on thick layers of Au (2000 Angstroms); these systems were supported on chromium-primed silicon wafers. Trifluoroacetyl-terminated SAMs were assembled on these substrates and the samples irradiated with monochromatic A1 Kalpha X-rays. The fluxes of X rays to which the different samples were exposed were the same, but the fluxes and energy distributions of the electrons generated by interactions of the X rays with the substrates differed. The loss of fluorine from the SAMs was followed by XPS and was slower on substrates emitting a lower flux of electrons. This observation indicated that the electrons, and not the X rays themselves, were largely responsible for the damage to the organic monolayer films that resulted in loss of fluorine from them
Comparison of Self-Assembled Monolayers on Gold: Coadsorption of Thiols and Disulfides ( Book )
1 edition published in 1989 in English and held by 1 WorldCat member library worldwide
Ordered, organic monolayers were formed on gold slides by adsorption from ethanol of HS(CH2)10CH2OH, HS(CH2)10CH3, S(CH2)10CH2OH2, S(CH2)10Ch32, and of binary mixtures of these molecules in which one component was terminated by a hydrophobic methyl group and one by a hydrophilic alcohol group. The compositions of the monolayers were determined by X-ray photoelectron spectroscopy (XPS). Wettability was used as a probe of the chemical composition and structure of the surface of the monolayer. When monolayers were formed in solutions containing mixtures of a thiol and a disulfide, adsorption of the thiol was strongly preferred (approx. 75:1).

The Anthranilate Amide of 'Polyethylene Carboxylic Acid' Shows and Exceptionally Large Change with pH in Its Wettability by Water ( Book )
1 edition published in 1988 in English and held by 1 WorldCat member library worldwide
The amide formed from polyethylene carboxylic acid (PE-CO2H) and anthranilic acid shows an exceptionally large change in wettability by water with pH. The values of advancing contact angles theta(a) are theta(a)(pH 1) = 110 degs and theta(a)(pH 12) = 33 degs. Comparison of these values with those for corresponding amides of meta- and para-aminobenzoic acid and aniline suggest that both conformational mobility of the polar functional group at the solid-water interface and surface roughness contribute to this large value.

Omega-Terminated Alkanethiolate Monolayers on Surfaces of Copper, Silver and Gold Have Similar Wettabilities ( Book )
1 edition published in 1991 in English and held by 1 WorldCat member library worldwide
Long chain alkanethiols (HS(CH2)nX) adsorb from solution onto the surfaces of freshly evaporated copper, silver and gold films and form oriented monolayers. Both polar and non-polar tail groups (X) can be accommodated in these adsorptions. Adsorption on all three metals generates self-assembled monolayers (SAMs) exhibiting similar wetting properties, and thus, by inference, having related oriented structures. XPS data suggest that the omega-terminated eta-alkanethiolate monolayers, like those derived from simple alkanethiols, are composed of trans-extended chains having orientations on copper and silver that are closer to the perpendicular to the surface than are those on gold. We have prepared and characterized monolayers (mixed monolayers) by exposure of all three metals to mixtures of HS (CH2)11OH and HS9CH2)11CH3
