Rheological Characteristics of Human Saliva
The book titled "Rheological Characteristics of Human Saliva" is structured into four chapters. It examines how saliva behaves under mechanical forces, focusing on its flow and deformation properties. Saliva plays an essential role in mastication, swallowing, speech, and digestion, and its rheological behavior is key to these functions. As a pseudoplastic, non-Newtonian fluid, saliva becomes less viscous with increased shear rate. This allows it to flow more easily during activities like chewing or speaking, while remaining more viscous at rest to protect and hydrate the oral mucosa. Its viscosity varies depending on the type of salivary gland-parotid saliva is more watery, while submandibular and sublingual secretions are thicker and more mucinous. Stimulation reduces viscosity, and factors such as hydration, health, stress, and diet also influence its rheological properties.

Existence of Internal and External Valences in Chemical Clusters
The chemical clusters analyzed and categorized in this book demonstrate the fact that the driving force behind the chemical reactions is the desire for the nodal points of each chemical element in the cluster ATTAINS A NOBLE GAS CONFIGURATION. Just like a hydrogen ligand (H), a skeletal linkage to a nodal point in a cluster behaves as SINGLE ELECTRON DONOR. Regarding electron counting at a NODAL POINT, it has been found easier to consider electrons on the skeletal element as an INTERNAL VALENCY ( V1 ) AND THOSE DONATED BY SKELETAL LINKAGES AND LIGANDS AS EXTERNAL VALENCE (V2). The sum of V1+V2=8 FOR MAIN GROUP ELEMENTS, V1+V2=18 FOR TRANSITION ELEMENTS AND V1+V2=32 FOR LANTHANIDES/ACTINIDES. A wide range of examples to illustrate this concept for main group and transition elements are provided in this book.

Interesting Materials
The book titled "Interesting Materials: Graphene and Graphene Oxide" is structured into four chapters. In recent years, a new material called graphene has emerged within the field of advanced nanomaterials and is being extensively explored by scientists and engineers. Graphene is a two-dimensional (2D) allotrope of carbon, in which sp簡-hybridized carbon atoms are covalently bonded in a hexagonal lattice to form a single atomic sheet. It is now understood that graphene is the fundamental building block of other carbon allotropes, such as graphite, single-walled/multi-walled carbon nanotubes, and fullerenes. Over the past five years, chemically modified graphene (CMG) has been studied for a wide range of applications-including polymer composites, energy materials, sensors, paper-like materials, field-effect transistors (FETs), and biomedical uses-thanks to its excellent electrical, mechanical, and thermal properties. The chemical modification of graphene oxide, derived from graphite oxide, has become a promising method for the large-scale production of CMG platelets.

Blackened silver and gold production
In this book, the authors will reveal theoretical mechanism of formation of electrolytic oxygen bubbles during water electrolysis for intensive formation of microdispersed oxygen bubbles on a jewelry silver or gold anode (oxidation), which allowed developing a new electrochemical method of blackening silver or gold. Authors will present the developed on the mechanism basis electrolyzer, which in practice implemented a new electrochemical method of blackening silver or gold. It will be shown that developed electrolyzer made it possible to blacken silver or gold jewelry with a thin, durable and indelible black film, which does not require careful maintenance, like regular silver or gold, retains its magnificent appearance longer and is distinguished by its high strength, bactericidal properties of silver, which help destroy pathogenic bacteria and microbes on the surface of the skin. Black gold jewelry, obtained by the developed method, is uniformly saturated with a thin black film, stylish and wear-resistant and is not expensive. The resulting black gold has a universal fashionable color, combined with white gold in classic jewelry.
