The choice of surfactant or surfactant mixtures at suitable concentrations contributes to the stability of solid lipid nanoparticles (SLN). In this study, it was found that 1.5% TegoCare 450 was the most effective stabilizer for the Witepsol E85 SLN dispersion compared to Tween 80, Tyloxapol and Pluronic F68 according to the data obtained from differential scanning calorimetry (DSC), zeta potential (ZP) measurements and particle size analysis.

This study utilized deep eutectic solvents (DES) based on choline chloride/lactic acid (ChCl/LA) to deconstruct coconut fibers. The effects of DES with different temperatures and molar ratios on the yield of lignin, recovery rate of residues, structural changes in lignin and solid residues, and saccharification efficiency were investigated. The results showed that acidic DES treatment effectively deconstructed the coconut fibers, resulting in a high lignin yield of 68.

Proper waste management and sustainable energy production are crucial for human development. For this purpose, this study evaluates the impact of blending percentage on energy recovery potential and environmental benefits of co-combustion of wastewater sludge and Brazilian low-rank coal. The sludge and coal were characterised in terms of their potential as fuel and co-combustion tests were carried out in a pilot-scale bubbling fluidised bed focused on the influence of the percentage of sludge mixture on the behaviour of co-combustion with coal in terms of flue gas composition and fluidised bed temperature stability.

In this work, UiO-66-l-cys with enhanced adsorption capacity for Hg(Ⅱ) in water was synthesized through a facile two-step partial ligand replacement strategy. The presence of the functional groups significantly enhanced the capacity of the material for Hg(Ⅱ). According to the Langmuir model, the maximum theoretical adsorption capacity was calculated to be 1321.

The development of stable biopharmaceutical formulations, such as monoclonal antibodies, poses a great challenge in the pharmaceutical industry. This study investigated the stabilizing effect of 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) in liquid and solid formulations of infliximab during processing and storage. The solid formulation was produced by a scaled-up high-speed electrospinning method, resulting in a product suitable for reconstitution with excellent dissolution properties.

A universal and green catalytic system for the hydrogenation of unsaturated aldehydes and ketones into the corresponding alcohols with the CC bonds retained under atmospheric hydrogen pressure in the water phase was realized by -functionalized amino ligand-stabilized ruthenium complexes (-PPhCHNHMe)[(CHNHR)]RuCl (R = H, Me, Et) and (-PPhCHNMe)[(CHNHEt)]RuCl with wide substrate compatibility and excellent functionality tolerance. The structural synergism between -PPhCHNHMe and (CHNHEt) achieves the enhanced performance, with a positive correlation with the electron density of the amino ligand.
