10 editions published between 1997 and 2007 in English and held by 834 WorldCat member libraries worldwide

"How many electrons can dance on the head of a pin? What do DNA strands look like when chased by an electrical charge? Using innovative photographic technology, MIT artist-in-residence Felice Frankel finds startling abstract beauty in the undulations of liquid crystal film, the gymnastics of plastic microstructures, the migratory trudge of bacteria, and other scientific wonders." "What do these experiments teach us, and how might such scientific innovations affect our world? A fascinating text by world-renowned Harvard chemistry professor George M. Whitesides explains each photograph, describing why and how each of these phenomena occur."--Jacket
No small matter : science on the nanoscale by Felice Frankel( Book )

12 editions published between 2009 and 2011 in 3 languages and held by 811 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 )

5 editions published between 2013 and 2014 in English and held by 15 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). This is truly an impressive body of work, which advances a transformative collection of concepts that could impact many areas of society and science. The ideas of this study are exciting. Tinsley Oden, University of Texas, Austin (April 2013) The CKTS study presents inspirational ideas behind the concept of convergence and identifies ground-breaking opportunities for human progress through such convergence. Christos Tokamanis, Nanotechnology and Converging Technologies, EU, Brussels (May 2013) The study provides a systematic and unified, internationally benchmarked framework for convergence that is relevant to policymakers, entrepreneurs, researchers, and the general public. Jo-Won Lee, Hanyang University, Korea (June 2013) I consider .. the first NBIC study in 2001.. as an historical landmark that has caused a new dynamic in the reflection on these new technologies within the broad scientific and governmental community.

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.

Attenuation Lengths of Photoelectrons in Hydrocarbon Films( Book )

2 editions published in 1988 in English and held by 1 WorldCat member library 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)
Acid-Base Behavior of Carboxylic Acid Groups Covalently Attached at the Surface of Polyethylene( Book )

2 editions published between 1983 and 1985 in English and held by 1 WorldCat member library worldwide

Oxidation of low-density polyethylene film with chromic acid/sulfur acid at 72 C generates a material (PE-CO2H) having a high density of carboxylic acid and ketone functionalities in a thin surface layer on the polymer. Similar oxidation of low density polyethylene powder (powder PE-CO2H) and ultrahigh molecular weight polyethylene (UHMW-CO2H) generate materials having only slightly different properties. This paper determines extent of the ionization of the surface and near-surface carboxylic acis groups of these materials in contact with water as a function of pH using three experimental techniques: measurement of attenuated total reflectance infrared (ATR-IR) spectra, measurement of contact angles, and direct potentiometric titration. The first and third techniques measure the concentrations of carboxylic acid and carboxylate groups throughout the polymer surface and near-surface region. The second technique relies on differences in the hydrophilicity of carboxylic acid and carboxylate groups to produce differences in the polymer-water interfacial free energy. This technique is sensitive primarily to surface functionality. On the basis of correlations between results obtained using these three techniques, we propose an equation (eq 6) relating the contact angel of an aqueous solution having a given value of pH on PE-CO2H and UHMW-CO2H and the extent of ionization of those carboxylic acid groups which are directly exposed to the solution

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
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)
The configurational stability of primary Grignard reagents. Applications of nuclear magnetic resonance spectroscopy to the study of molecular asymmetry by G. M Whitesides( )

1 edition published in 1964 in Undetermined and held by 1 WorldCat member library worldwide

Part I. The Configurational Stability of Primary Grignard Reagents. Examination of the temperature dependence of the nuclear magnetic resonance spectrum of 3,3-dimethylbutylmagnesium chloride in diethyl ether solution indicates that inversion of configuration at the methylene group of this Grignard reagent occurs with an approximate rate of 10 sec.[superscript -1] at room temperature. The dependence of the rate of inversion on solvent and on the structure of the Grignard reagent is discussed in terms of possible mechanisms for the inversion. Part II. Applications of Nuclear Magnetic Resonance Spectroscopy to the Study of Molecular Asymmetry. The methylene protons of 1-phenylethyl benzyl ether are magnetically non-equivalent and display an AB-type nuclear magnetic resonance spectrum. The variation in the spectrum of this compound and in the spectra of other structurally similar ethers with solvent indicates that the principal contribution to the magnetic non-equivalence of the methylene protons originates in the magnetic anisotropy of the phenyl group bonded directly to the methylene group. It is suggested that the solvent dependence of these spectra reflects changes in the populations of the possible rotational conformations open to the molecule
The Structure and Reactivity of Alkylsiloxane Monolayers Formed by Reaction of Alkyltrichlorosilanes on Silicon Substrates( Book )

1 edition published in 1989 in English and held by 1 WorldCat member library worldwide

Long-chain alkyltrichlorosilanes, C13Si (CH2)nX, adsorb from solution onto silicon-silicon dioxide (Si/SiO2) substrates and form ordered alkylsiloxane monolayer films. These films were characterized by wettability, ellipsometry, and XPS. Except for very short chains (n = 0,1,2), the wetting of these monolayers was approximately independent of chain length. The presence of small amounts of water was necessary for the formation of these films. The alkylsiloxane monolayers were stable in common organic solvents, water, and acid, but were destroyed by prolonged exposure to base. Simple reactions on vinyl-terminated monolayers generated alcohol-, carboxylic acid-, and bromine- terminated films whose contact angles were lower than the starting monolayers, but whose lengths were largely unchanged. Measurements of the contact angle of acid-terminated interfaces as a function of pH indicated that ionization of soluble carboxylic acids. Monolayers containing mixtures of methyl- and carboxyl-functionalities exhibited wetting properties that mirrored the composition of the interface

The possibility that terms other than Fermi contact interaction make significant contributions to nuclear spin-spin coupling with heavy nuclei has stimulated considerable interest in the nmr spectra of compounds containing heteroatoms. In particular, relative signs and magnitudes of J sub XCH and J sub XCCH have been reported for ethyl derivatives of several heavy isotopes of spin 1/2. Inorder to understand better the factors responsible for spin couping with a representative heavy nucleus, we have analyzed the spectra of (CH3)3P, (CH3)2PH and (CH3)PH2 and have obtained relative signs and magnitudes of J sub PH and J sub PCH
