Acoustical characteristic of empty fruit bunch (EFB) fibre with influence of sodium hydroxide treatment time and decay lifespan [PDF]

open access: yes, 2019
Research on natural fibres has gain much interest in recent years due to the sustaibability and avaibility in which demand for green renewable reinforced composites. Natural fibres can be considered as the alternative way to replace the synthetic fibre

Novel hybrid flax reinforced supersap composites in automotive applications [PDF]

open access: yes, 2015
Flax fibre bio-epoxy composites have not found many commercial uses in structural applications on account of their lack of cost efficiency and high susceptibility to environmental changes. Non-woven flax mats were subjected to alkali, acetylation, silane

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

Identification of the effects of alkalinity exposure on the gills of oriental river prawns, Macrobrachium nipponense

open access: yesBMC Genomics
Macrobrachium nipponense is an important commercial freshwater species in China. However, the ability of alkali tolerance of M. nipponense is insufficient to culture in the major saline-alkali water source in China. Thus, it is urgently needed to perform

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Organic mass and protein extraction from secondary sewage sludge via multi-step physical alkali- and acid-based treatment

open access: yesFrontiers in Chemical Engineering
The perception of sewage sludge has been shifting from waste to resource, leading to various technological proposals for its management and resource recovery. This study explores a two-step sewage sludge treatment using different pathways—physical-alkali

ALKALI-TREATMENT OF CHLORINATED POLYESTER FIBER

open access: yesSen'i Gakkaishi, 1978
Chlorinated polyester fabric with upto 20% chlorine content was prepared by irradiating the fabric in chlorine gas at about atmospheric pressure with γ-rays at room temperature.When the chlorinated fabrics were subjected to an alkali-treatment such as heating up to 100°C in aqueous solution of sodium carbonate, it caused, more or less, a weight loss ...

Synthesis of CoAl2O4 by double decomposition reaction between LiAlO2 and molten KCoCl3 [PDF]

open access: yes, 2008
Submicronic CoAl2O4 powders were prepared by double decomposition reaction between solid LiAlO2 and molten KCoCl3 at 500 ◦C for 24 h. The reaction mechanism involves the dissolution of LiAlO2 shifted by the precipitation of CoAl2O4 until complete ...
