Special Issue Information

Dear Colleagues,

We have the honor and pleasure to organize the 3rd National Symposium on Bioorganic, Organic and Biomaterial Chemistry "BioOrg 2019" in Poznań, Poland, December 7, 2019. In connection with this event, we would like to invite you to share the results of your research in the Molecules Special Issue entitled "BioOrg: From Biomolecules to Biomaterials".

We participate in the dynamic development of chemistry and biochemistry, during which new and innovative solutions become particularly important. To meet the requirements of green chemistry and sustainable development, many interesting studies are carried out using advanced methods. The main purpose of the “BioOrg 2019” symposium as well as the presented Special Issue is to highlight the most interesting studies in the field of biomolecules chemistry and biochemistry as well as biobased advanced materials. Moreover, of interest will be studies dealing with the processes of biotransformation of organic compounds and organic synthesis of bioactive and pharmaceutical compounds. In addition, we expect that carbohydrate and protein chemistry—in particular, enzymes, including enzymes immobilization and biocatalysis—biosensors will also appear among published studies. Furthermore, we encourage you to share your experience on biomolecule purification processes and their thorough analysis. An equally important topic of research which is included in the scope of this Special issue is related to the fabrication and characteristic of multifunctional biomaterials with various applications, including biomass valorization.

We hope that the proposed Special Issue will offer a comprehensive and interesting view and be an important source of successful solutions in modern biomolecule and biomaterial chemistry.

Preparation of Nanocellulose Using Ionic Liquids: 1-Propyl-3-Methylimidazolium Chloride and 1-Ethyl-3-Methylimidazolium Chloride
Molecules 2020, 25(7), 1544; https://doi.org/10.3390/molecules25071544 - 28 Mar 2020
Abstract
Cellulose nanocrystals were prepared using ionic liquids (ILs), 1-ethyl-3-methylimidazolium chloride [EMIM][Cl] and 1-propyl-3-methylimidazolium chloride [PMIM][Cl], from microcrystalline cellulose. The resultant samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), scanning electron microscopy (SEM), and transmission electron [...] Read more.
Cellulose nanocrystals were prepared using ionic liquids (ILs), 1-ethyl-3-methylimidazolium chloride [EMIM][Cl] and 1-propyl-3-methylimidazolium chloride [PMIM][Cl], from microcrystalline cellulose. The resultant samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The XRD results showed that nanocellulose obtained by treatment with both ILs preserved basic cellulose I structure, but crystallinity index of samples (except for Sigmacell treated with [EMIM][Cl]) was lower in comparison to the starting microcrystalline cellulose. The DLS results indicated noticeably smaller particle sizes of prepared cellulose for material treated with [PMIM][Cl] compared to cellulose samples hydrolyzed with [EMIM][Cl], which were prone to agglomeration. The obtained nanocellulose had a rod-like structure that was confirmed by electron microscopy analyses. Moreover, the results described in this paper indicate that cation type of ILs influences particle size and morphology of cellulose after treatment with ionic liquids. Full article

In this paper, we present the possibility of using pea protein isolates as a stabilizer for hempseed oil (HSO)-based water/oil emulsions in conjunction with lecithin as a co-surfactant. A Box-Behnken design was employed to build polynomial models for optimization of the ultrasonication process to prepare the emulsions. The stability of the system was verified by droplet size measurements using dynamic light scattering (DLS) as well as centrifugation and thermal challenge tests. The z-ave droplet diameters of optimized emulsion were 209 and 207 nm after preparation and 1 week storage, respectively. The concentration of free Linoleic acid (C18:2; n-6) was used for calculation of entrapment efficiency in prepared nanoemulsions. At optimum conditions of the process, up to 98.63% ± 1.95 of entrapment was achieved. FTIR analysis and rheological tests were also performed to evaluate the quality of oil and emulsion, and to verify the close-to-water like behavior of the prepared samples compared to the viscous nature of the original oil. Obtained results confirmed the high impact of lecithin and pea protein concentrations on the emulsion droplet size and homogeneity confirmed by microscopic imaging. The presented results are the first steps towards using hempseed oil-based emulsions as a potential food additive carrier, such as flavor. Furthermore, the good stability of the prepared nanoemulsion gives opportunities for potential use in biomedical and cosmetic applications. Full article
