Removal of 2,4-Dichlorophenoxyacetic Acid from Aqueous Solutions Using Al₂O₃/Graphene Oxide Granules Prepared by Spray-Drying Method

Resources
Within this study, aluminum oxide granules with 0.25%vol. of graphene oxide were prepared by a spray-drying method to make an adsorbent for the 2,4-Dichlorophenoxyacetic acid (2,4-D) herbicide removal from aqueous solutions.

Sintering studies on ceramic fuel materials.

, 1964
Satisfactory dense crack—free dispersions of spheroidal U02 — Th02 particles in BeO can be produced by "co-sintering", a process in which unsintered particles are hydrostatically pressed in BeO and the dispersion is sintered in one step, the large voids ...

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Mechanical properties variation of samples fabricated by fused deposition additive manufacturing as a function of filler percentage and structure for different plastics

Scientific Reports
One of the key factors in manufacturing products by fused deposition molding (FDM) or layer-by-layer printing technology is the material intensity of the product.

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Finite element analysis of curl development in the selective laser sintering process [PDF]

, 2001
Selective laser sintering (SLS) is a rapid prototyping process, which operates by using a laser to locally heat an area within a layer of powder material, causing it to fuse together, creating a thin cross-section of solid material.

Determination of Annealing Temperature of Thin-Walled Samples from Al-Mn-Mg-Ti-Zr Alloys for Mechanical Properties Restoration of Defective Parts After SLM

Journal of Manufacturing and Materials Processing
The aim of this work is to investigate the effect of annealing (at temperatures ranging from 260 °C to 530 °C) of thin-walled Al-Mn-Mg-Ti-Zr samples manufactured by selective laser melting (SLM) on their tensile mechanical properties, hardness, and ...

Sintering by volume diffusion.

, 1964
The process of sintering by volume diffusion has been subjected to a critical review. Various stages in the sintering process have been identified. It has been shown that sintering is most effective when the porosity takes the form of continuous pore ...
