FUERZAS DE SUPERFICIE Y ADHESIÓN EN SISTEMAS CELULÓSICOS: NUEVA FORMA DE EVALUAR FIJACIÓN/DISPERSIÓN DE RESINA EN LA FABRICACIÓN DE PAPEL/CELULOSA SURFACE FORCES AND ADHESION IN CELLULOSE SYSTEMS: NEW WAY TO EVALUATE RESIN FIXATION/DISPERSION IN THE MANUFACTURE OF PAPER/CELLULOSE

open access: yesMaderas: Ciencia y Tecnología, 2010
Las fuerzas superficiales entre partículas coloidales de resina y fibra dominan el comportamiento y las propiedades finales de papel y celulosa. Aquí se describe el uso de Microscopía de Fuerza Atómica (AFM) para medir directamente las fuerzas de ...

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

The Anisotropic Adsorption of De Novo Allosteric Two‐Component Protein Fibers on Mica Surfaces

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interfacial behavior of de novo designed proteins that self‐assemble into tubular architectures with distinct morphologies — small (S), large (L), and helical (H) fibers — at the muscovite mica‐water interface is explored using in situ AFM. Abstract Protein adsorption at solid–liquid interfaces underlies many biomedical and materials

Decoupler pylon: wing/store flutter suppressor [PDF]

open access: yes, 1982
A device for suspending a store from a support such as an aircraft wing and more specifically for increasing the flutter speed of an aircraft flying with attached store and reducing the sensitivity of flutter to changes in the pitch inertia and center of

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Electron–Matter Interactions During Electron Beam Nanopatterning

open access: yesAdvanced Functional Materials, EarlyView.
This article reviews the electron–matter interactions important to nanopatterning with electron beam lithography (EBL). Electron–matter interactions, including secondary electron generation routes, polymer radiolysis, and electron beam induced charging, are discussed.

North Wind 4kW passive control system design [PDF]

open access: yes, 1981
An overview of a mechanical rotor control design is presented. Operation at constant RPM and rapid response are obtained by using blade pitch moments for both sensing control need and blade pitch actuation. The basic concept, static or equilibrium design,

Kinematics of the swimming of Spiroplasma

open access: yes, 2009
\emph{Spiroplasma} swimming is studied with a simple model based on resistive-force theory. Specifically, we consider a bacterium shaped in the form of a helix that propagates traveling-wave distortions which flip the handedness of the helical cell body.
