Special Issue Information

Dear Colleagues,

From the 4th to 7th September 2022 in Ascea (Italy), “The V International Summer School on Cyclodextrins, advances in cyclodextrin chemistry and applications” will be held, where graduate students, Ph.D. students, post-doc students, young and senior researchers interested in all the aspects of cyclodextrin chemistry and applications will share their knowledge and learn about this topic. Cyclic oligosaccharides, discovered by Antoine Villiers in 1891, have had great scientific repercussions; although, in the beginning, the main function of this ring was to encapsulate in its interior compounds that, due to size or interaction, were stabilized in its hydrophobic cavity. However, different researchers have been modifying them to overcome this limitation and reach different applications. This is why they have found a great reception in the current scientific field, with innumerable applications in fields as disparate as pharmacology, food, energy or nuclear science, with more than 21,500 publications in the last 10 years (ISI web of science). This Special Issue is about the current state-of-the-art of systems of cyclodextrin chemistry and application in different fields, providing useful dissemination of the latest information. The Special Issue covers several aspects, from synthesis and characterization to application.

Due to their high energy and power density, lithium-ion batteries (LIBs) have gained popularity in response to the demand for effective energy storage solutions. The importance of the electrode architecture in determining battery performance highlights the demand for optimization. By developing useful organic polymers, cyclodextrin architectures have been investigated to improve the performance of Li-based batteries. The macrocyclic oligosaccharides known as cyclodextrins (CDs) have relatively hydrophobic cavities that can enclose other molecules. There are many industries where this “host–guest” relationship has been found useful. The hydrogen bonding and suitable inner cavity diameter of CD have led to its selection as a lithium-ion diffusion channel. CDs have also been used as solid electrolytes for solid-state batteries and as separators and binders to ensure adhesion between electrode components. This review gives a general overview of CD-based materials and how they are used in battery components, highlighting their advantages. Full article

Cyclodextrins (CDs) are cyclic oligosaccharides that emerged as industrial excipients in the early 1970s and are currently found in at least 130 marketed pharmaceutical products, in addition to numerous other consumer products. Although CDs have been the subject of close to 100,000 publications since their discovery, and although their structure and properties appear to be trivial, CDs are constantly surprising investigators by their unique physicochemical properties. In aqueous solutions, CDs are solubilizing complexing agents of poorly soluble drugs while they can also act as organic cosolvents like ethanol. CDs and their complexes self-assemble in aqueous solutions to form both nano- and microparticles. The nanoparticles have diameters that are well below the wavelength of visible light; thus, the solutions appear to be clear. However, the nanoparticles can result in erroneous conclusions and misinterpretations of experimental results. CDs can act as penetration enhancers, increasing drug permeation through lipophilic membranes, but they do so without affecting the membrane barrier. This review is an account of some of the unexpected results the authors have encountered during their studies of CDs as pharmaceutical excipients. Full article
