Electro-brightening of mechanical pulp

, 2000
The electro-oxidation of sodium carbonate (Na₂C0₃) to percarbonate (C₂O₆²⁻), with its subsequent hydrolysis was investigated as a means to produce peroxide and to drive the in-situ electrochemical brightening of thermo-mechanical pulp.

Revealing the Atomic‐Scale Structure of the Copper–Sulfuric Acid Interface

Small Methods, EarlyView.
How do acids interact with metallic surfaces? Using a multidisciplinary approach of electrodeposition and 3D‐printing, a novel approach of micro‐corrosion cells enables cryogenic atom probe tomography at the liquid‐solid interface of dilute sulfuric acid in contact with copper at different time and thermal conditions. ABSTRACT Corrosion originates from

A Multi‐Analytical Campaign on Reused Medieval Musical Parchment From the Archivio di Stato di Siena (Italy)

X-Ray Spectrometry, EarlyView.
ABSTRACT In this study, a non‐invasive, multi‐analytical approach combining hypercolorimetric multispectral imaging (HMI), stereomicroscopy, X‐ray fluorescence (XRF) spectroscopy, principal component analysis (PCA) and X‐ray radiography (RX) is used to investigate three reused musical parchment fragments dating from the late 14th or early 15th century ...

The Mysterious Stranger and Modern Enchantment

The British Journal of Sociology, EarlyView.
ABSTRACT Sociological accounts of modernity have long emphasized rationalization, alienation, and the attenuation of affective intensity. While these diagnoses capture crucial dynamics of modern social order, they leave underexplored a persistent and generative dimension of social life: enchantment.

The detection of latent fingermarks on semi‐porous substrates with UV‐C and the full spectrum imaging system (FSIS‐II)

Journal of Forensic Sciences, EarlyView.
Abstract The use of UV‐C imaging for the detection of latent fingermarks has been reported since the 1970s; however, widespread adoption has been limited due to health and safety concerns as well as its possible detrimental effects on DNA evidence. Semi‐porous substrates may not be suitable for processing with methods recommended for porous or non ...

Subset of Fluorophores Is Responsible for Radiation Brightening in Viromimetic Particles

, 2021
In certain conditions, dye-conjugated icosahedral virus shells exhibit suppression of concentration quenching. The recently observed radiation brightening at high fluorophore densities has been attributed to coherent emission, i.e., to a cooperative ...

The Redemption of a Forgotten War: Korea in Australian Memory and Commemoration

Australian Journal of Politics &History, EarlyView.
ABSTRACT This article examines how the Korean War has been remembered in Australia despite its historically marginal place in the nation's military heritage. By detailing Australian memories of the Korean War across official, quasi‐official, and unofficial histories, it shows that Korea occupied only a minor position in Australia's military imaginary ...
