Novel Double Hybrid-Type Bone Cements Based on Calcium Phosphates, Chitosan and Citrus Pectin
(MDPI, 2023-08-30)In this work, the influence of the liquid phase composition on the physicochemical properties of double hybrid-type bone substitutes was investigated. The solid phase of obtained biomicroconcretes was composed of highly ... -
CO2-Assisted Dehydrogenation of Propane to Propene over Zn-BEA Zeolites: Impact of Acid–Base Characteristics on Catalytic Performance
(MDPI, 2023-03-31)Research results about the influence of BEA zeolite preliminary dealumination on the acid–base characteristics and catalytic performance of 1% Zn-BEA compositions in propane dehydrogenation with CO2 are presented. The ... -
Amino-Acids Surfactants and n-Octanol Mixtures─Sustainable, Efficient, and Dynamically Triggered Foaming Systems
(American Chemical Society, 2023-08-17)Surfactants with amino-acid heads (AASs), namely N-lauroyl-l-alanine (C12-ALA), N-lauroyl-l-leucine (C12-LEU), and N-lauroyl-l phenylalanine (C12-PHE) were mixed with n-octanol (C8OH) and thoroughly investigated via surface ... -
Bubble Formation and Motion in Liquids—A Review
(MDPI, 2023-08-26)In flotation, a bubble acts as a carrier for attached particles. The properties of the gas–liquid interface of the bubble are one of the main factors determining the bubble motion and flotation efficiency. Monitoring of ... -
Towards green flotation: Investigating the effect of rhamnolipid biosurfactant on single bubble adhesion dynamics
(Elsevier B.V. All, 2023-08-04)In this study we performed an experimental analysis of the influence of rhamnolipid (RL) biosurfactant produced by Pseudomonas aeruginosa on the dynamics of bubble adhesion onto model surfaces of various hydrophobicity. ... -
Experimental and theoretical study of adsorption of synthesized amino acid core derived surfactants at an air/water interface
(The Royal Society of Chemistry, 2022-01-20)The adsorption characteristics of amino acid surfactants, synthesized as substances with different volumes and hydrophilic head properties, have been previously described experimentally, without robust theoretical explanation. ... -
Molecular mechanisms of pH-tunable stability and surface coverage of polypeptide films
(Elsevier, 2023)Streaming potential and quartz crystal microbalance measurements, combined with all-atom molecular dynamics simulations, were used to study the pH dependency of the adsorption of two basic homopolypeptides, poly-L-lysine ...
