A Review of 3D Printing Technology for Medical Applications - ScienceDirect
In addition, highly controlled printing environments ensure high purity of the printed parts, thus maintaining the desired characteristics of the material. Moreover, the design complexity of 3D printed personalized products is reduced, allowing
The present work describes the preparation of nano-lignin particles from calcium lignosulfonate (CL). The nano-lignin was fabricated from colloidal lignin–polyacrylamide complexes via self-assembly. The sizes of the nano-lignin particles were

Darcy’s law was used to calculate the effective permeability to oil and effective permeability to water at irreducible water saturation and residual oil saturation , respectively.For a horizontal linear system, flow rate is related to
Surface and Interface Engineering for Nanocellulosic Advanced Materials - Yang- Advanced Materials - Wiley Online Library
This way we obtain nanocelluloses with high purity but at the expenses of low yield (40–50% or even lower), [] high environmental hazards, and high production cost. The limitations of these nanocelluloses in material formation are already known
In this process, a prehydrolysis step is used to extract most of the hemicelluloses, followed by kraft pulping to remove most of the lignin, and a bleaching/purification step which results in the production of dissolving pulp with a high cellulo

Thin-layer aluminium recycling and refinery seems to be a promising approach capable of producing high-purity aluminium with low specific energy consumption. Full article (This article belongs to the Special Issue Advances in Understanding of
Carnauba wax has very good emulsification properties and excellent oil-binding capacity for ester oils and mineral oils. It also raises the melting point of gels, thus making it the preferred additives in lipsticks, lip balms, and mascara. It
Hydrogen production by PEM water electrolysis – A review - ScienceDirect
High current densities Compact system design and Quick Response Greater hydrogen production rate with High purity of gases (99.99%) Higher energy efficiency (80–90%) High dynamic operation New and partially established High cost of components
Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl
