High‐Performance Electrocatalysts of Potassium Lactate Oxidation for Hydrogen and Solid Potassium Acetate Production

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Potassium lactate, produced from polylactic acid plastic waste, is oxidized to potassium acetate on an anode using Ni(Co)OOH as the electrocatalyst, while hydrogen is simultaneously generated at the cathode, through a highly efficient industrial‐scale electrolysis system.

Two Material Properties from One Wavelength‐Orthogonal Photoresin Enabled by a Monochromatic Laser Integrated Stereolithographic Apparatus (Mono LISA)

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A single object with dual properties – degradable and non‐degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi‐material printing is enabled by the combination of a fully wavelength‐orthogonal photoresin and a monochromatic tunable laser printer, paving the way for precise multi‐material ...

Viewpoint: Is critical art librarianship actually a thing? [PDF]

open access: yesArt Libraries Journal, 2019
If I'm being honest I still feel as though I am a bit of an imposter in the world of art librarianship. I often feel as though I have a very conservative, corporate and conformist approach to librarianship within the art library environments in which I work. I also often feel naïve when it comes to discussing and affirming ‘what makes art librarianship

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

open access: yesAdvanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

Single‐Atom Photocatalyst as Floatable Artificial Leaf for Upcycling Oceanic Plastic Waste

open access: yesAdvanced Materials, EarlyView.
To resolve the catastrophic disaster of oceanic plastic pollution, the novel Ru single atom loaded ZnIn2S4 photocatalysts, in the forms of powder or floatable artificial leaf, were prepared for direct conversion of raw polypropylene plastic into valuable chemicals. The optimized catalyst exhibits exceptional performance, with a total formic/acetic acid

Institutionalization of progressist and critical librarianship

open access: yes, 2021
“Outra Biblioteconomia” vem sendo praticada e produzida com características distintas. As designações dessas Biblioteconomias que se opõem a uma vertente conservadora são mormente conhecidas como: Biblioteconomia Progressista e Crítica. Assim, por meio de uma pesquisa exploratória, de cunho bibliográfico, buscaremos dar luz aos marcos institucionais ...
