Key bacterial groups maintain stream multifunctionality in response to episodic drying

open access: yesLimnology and Oceanography Letters, Volume 9, Issue 3, Page 286-295, June 2024.
Abstract Microbial biodiversity is fundamental to maintain ecosystem functioning in seasonally variable ecosystems. However, it remains unclear how alterations in water availability caused by episodic drying compromise the ability of stream microbes to maintain multiple functions simultaneously (e.g., primary production and carbon cycling).

Resisting extractivism as a feminist critical socio‐spatial practice

open access: yesGender, Work &Organization, Volume 31, Issue 3, Page 983-1011, May 2024.
Abstract This paper draws on feminist geographies of space, proposing a feminist critical spatial practice approach to study social movement organizing. Inspired by the work of Jane Rendell, a feminist theorist and architectural historian, we propose embodiment, materiality, affectivity, and alterity as co‐constitutive of feminist organizing ...

A Review on Quantum Dot‐Based Color Conversion Layers for Mini/Micro‐LED Displays: Packaging, Light Management, and Pixelation

open access: yesAdvanced Optical Materials, Volume 12, Issue 2, January 16, 2024.
Mini/micro‐light‐emitting diodes (LEDs) are regarded as a potential candidate for next‐generation display technology. A promising strategy of combining mini/micro‐LEDs with quantum dot (QD) color conversion layers has been widely investigated to realize a full‐color displays.

Finger-jointing of acetylated Scots pine using a conventional MUF resin

open access: yes, 2018
Acetylation of wood is a modification technique that chemically alters the wood substance and enhances several properties of wood. The basic principle is to impregnate wood with acetic anhydride to react and replace OH-groups with acetyl groups in the wood cell wall.

The Study of the Adhesive Activity and Modification Possibilities of Melamine-Urea-Formaldehyde (MUF), Urea-Formaldehyde (UF) Resins

open access: yesMaterial Science and Applied Chemistry, 2014
Two types of thermosetting resins MUF and UF have been used as glues for birch wood veneer. As resins modifiers polyvinylacetate emulsion (PVA), polyvinylbutiral (PVB) (powder and solution), rubber latex, adipic (Ad) and sebacic (Seb) acids have been utilized.
