Hydrogels
Hydrogels, as three-dimensional polymer networks, are able to retain a large amount of water in their swollen state. The biomedical application of hydrogels was initially hampered by the toxicity of cross-linking agents and the limitations of hydrogel formation under physiological conditions. However, emerging knowledge in polymer chemistry and an increased understanding of biological processes have resulted in the design of versatile materials and minimally invasive therapies.The novel but challenging properties of hydrogels are attracting the attention of researchers in the biological, medical, and pharmaceutical fields. In the last few years, new methods have been developed for the prepar...
Wettability and Interfacial Phenomena
Wettability at the solid/liquid interface, its dynamics, tunability, the influence of operating parameters, surface and interfacial phenomena play an increasingly significant role in a wide variety of applications, for example, material processing, nanotechnology, oil recovery, oil spills, chemical leaching, water management, and disease transmission. Although a mature field, it is experiencing dramatic developments on several fronts with emerging applications in new fields. This book presents a collection of eight chapters on nanoscale wetting phenomena, oil extraction from reservoir rocks, the role of coatings, particle morphology, surface roughness and viscosity in metal processing, and practical applications of superhydrophobic behaviour in cell culturing, isolation, anti-icing, anti-reflective and anti-corrosion coatings in the transportation and optical devices fields.
Chitin-Chitosan
Chitin is the second most abundant biopolymer after cellulose and is a resourceful copious and cheap biomaterial discovered in 1859 owing to significant industrial and technological utility. Raw chitin-chitosan resembles keratin in its biological functions. Chitin chemistry vastly developed via innate unparalleled biological features and exceptional physicochemical characters. Chitosan endures assorted chemical/physical modifications easily at free proactive functionalities, yet intact bulk properties are achieved through processing, viz., film, membrane, composite, hybrid, nanofibre, nanoparticle, hydrogel and scaffolds. Rapidly lessen bioresources signify chitosan as an option due to renewable eco-friendliness and drive embryonic myriad applications in S
Plant Secondary Metabolites
Plant secondary metabolites are plant-based natural products that display a variety of pharmacological effects. This book discusses the invaluable bioactivity and multifaceted potential of these compounds. The book describes the physico-chemical and biochemical aspects of the plant secondary metabolites along with the chemistry, therapeutics and future perspectives of these plant secondary metabolites. Moreover, the book also discusses about various sources of plant secondary metabolites, and the metabolite determination through various analytical techniques. It further describes the potential applications of plant secondary metabolites as anticancer and chemo preventive agents, their role a...
Surface Modification to Improve Properties of Materials
This book contains selected contributions on surface modification to improve the properties of solid materials. The surface properties are tailored either by functionalization, etching, or deposition of a thin coating. Functionalization is achieved by a brief treatment with non-equilibrium gaseous plasma containing suitable radicals that interact chemically with the material surface and thus enable the formation of rather stable functional groups. Etching is performed in order to modify the surface morphology. The etching parameters are selected in such a way that a rich morphology of the surfaces is achieved spontaneously on the sub-micrometer scale, without using masks. The combination of adequate surface morphology and functionalization of materials leads to superior surface properties which are particularly beneficial for the desired response upon incubation with biological matter. Alternatively, the materials are coated with a suitable thin film that is useful in various applications from food to aerospace industries.

Inscripții pe columna gimnasticii românești - Ediția a III-a, 2022
”Să te cunoşti, să te stăpâneşti, să te învingi, iată frumuseţea eternă a sportului, aspiraţiile adevăratului sportiv şi condiţiile succesului său”, spunea candva Pierre de Coubertin. Este și ideea principală care a stat la baza acestei a treia ediții a volumului “Inscripții pe columna gimnasticii românești - Ediția a III-a, 2022 “, autor jurnalistul Emanuel Fântâneanu. Cele peste 3000 pagini sunt o incursiune în istoria gimnasticii universale și noilor sale structuri organizatorice, pentru a desluși, poate mai bine, locul și rostul gimnasticii românești; drumul parcurs de acest sport pe melegurile noastre, plecând din secolele trecute și până azi, ...
Romanian Gymnastics
Since Nadia Comaneci captured the hearts of the world with her amazing performance at the 1976 Olympic Games in Montreal, one that would change the sport of gymnastics forever, Romania has been known throughout the world for its remarkable success in the sport of gymnastics.This limited edition, full-color album presents the history of Romanian gymnastics from the founding of the Romanian Gymnastics Federation in 1906 to the Romanian women's team that won five consecutive world championship titles under coach Octavian Belu between 1994 and 2001. This book was originally published on the occasion of the 1996 Olympic Games in Atlanta and to commemorate the 90th anniversary of the founding of the Romanian Gymnastics Federation. On the 25th anniversary of its original publication, Romanian Gymnastics is being reissued to celebrate the Tokyo Olympic Games. The book profiles each member of the 1996 Romanian Women's Gymnastics team. This collector's item is a must for every gymnastics fan.
