O PROCESSO AD(EO)D - UM NOVO CONCEITO
Ciência Florestal, 2009 In this study, cooking of the wood had been investigated until kappa numbers 17 and 14 for a process kinetically modified, elimination of oxygen delignification from the fiber line, and application of AD(EO)D and AD(PO)D techniques for pulp of kappa 17 ...

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Kappa number prediction based on cooking liquor measurements
, 2004 Abstract CLA 2000 Cooking Liquor Analyzer gives on-line information on cooking reactions during a cook. Alkali, total dissolved solids and lignin contents are measured during individual cooks in a batch digester house and from several circulations in a continuous digester.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, EarlyView.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Advanced Materials, EarlyView.Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

ESTUDO DA BRANQUEABILIDADE DA POLPA KRAFT DE EUCALIPTO
Ciência Florestal, 2015 The aim of this study was to evaluate how the pulp bleachability ability is correlated with the wood chemical characteristics, the cooking conditions, the kappa number of the brown pulp and the bleaching sequences, based on the pulp bleached brightness ...

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...
