Exploring Natural Product Chemistry
Global warming and, even more recently, the COVID pandemic have brought into public focus our dependence on science and the lens with which it considers the world. Science is providing opportunities for new ways of thinking and has always opened new avenues for creative thought and advances. This book examines and summarises the developments and changes in approaches to organic and natural product chemistry as seen through the published works of the author and seeks to place them in a philosophical and societal context. Demonstrating and explaining how scientists and, more particularly, chemists arrive at a world view, it will show how this is predicated not just by scientific advances but also by societal influences. The author uses personal experience to detail progress through science. Techniques used in such investigations are alluded to but not described in detail since the interested reader can access the full published papers if required. Interesting both to the general, scientifically literate reader and to the specialist wanting information on natural product chemistry, the book does not create a rulebook for carrying out natural product chemistry but rather examines the processes that lie beneath the development of natural product chemistry and how this enables chemists to examine and interpret the world. Students of chemistry (whatever their age or stage of career) may also be interested in reading how peer reviewed and published material relates to the wider society view.

Photocatalytic reduction of nitrate in water
Nitrate is one of the most commonly found compounds in watercourses due to the infinity and diversity of existing sources, whether natural or man-made. Its excess can lead to various health and environmental problems, but cheap and efficient ways of treating water contaminated with nitrate are not yet a reality. One of the ways of remediating aquifers or water sources contaminated with nitrate or nitrite, which can add low cost and efficiency, is the use of photocatalysis, which uses ultraviolet (UV) or visible radiation as an energy source for the degradation of nitrate and nitrite. Focusing on this form of treatment, new photocatalysts were synthesised for the reduction of nitrogenous species such as nitrate and nitrite to molecular nitrogen.
Chemical Thermodynamics and Kinetics
The book entitled "Chemical Thermodynamics and Kinetics" is structured into two chapters. Thermodynamics deals with the macroscopic study of phenomena of any nature, involving the transfer of energy in the form of heat and mechanical work. The name is derived from the Greek language and was created by Lord Kelvin, who also formulated the first definition of thermodynamics. In German, thermodynamics is also called W瓣rmelehre (theory of heat), a term created by Rudolf Clausius in his works on the mechanical theory of heat. Nowadays, thermodynamics represents one of the most logically structured branches of physics. Born at the beginning of the 19th century from the practical need to optimize the efficiency of steam engines, thermodynamics has become one of the classical disciplines of theoretical physics. Chemical kinetics (or reaction kinetics, less commonly called chemical dynamics) is a branch of physical chemistry that studies the rate and mechanism of chemical processes. It includes the investigation of how different experimental conditions can influence the rate of a chemical reaction and gathers information about reaction mechanisms and reaction transition states.

Cotton seeds are toxic due to 1.5% gossypol. Flax (Linum) belongs to the Linaceae family with about 200 varieties. It is a perennial, bushy textile plant like cotton.Hemp has the highest industrialization capacity among technical plants: nothing is wasted, and everything is recovered. Products from hemp range from rope to cosmetics and automotive industries. Additionally, after hemp cultivation, land becomes suitable for cereal crops the next year because hemp kills weeds. The amount of chemical fertilizer required is much lower compared to other crops.
Macroevolutionaries
One of the twentieth century's great paleontologists and science writers, Stephen Jay Gould was, for Bruce S. Lieberman and Niles Eldredge, also a close colleague and friend. In Macroevolutionaries, they take up the tradition of Gould's acclaimed essays on natural history, offering a series of wry and insightful reflections on the fields to which they have devoted their careers. Lieberman and Eldredge explore the major features of evolution, or "macroevolution," examining key issues in paleontology and their links to popular culture, philosophy, music, and the history of science. They focus on topics such as punctuated equilibria, mass extinctions, and the history of life--with detours including trilobites, Hollywood stuntmen, coywolves, birdwatching, and New Haven-style pizza. Lieberman and Eldredge's essays showcase their deep knowledge of the fossil record and keen appreciation of the arts and culture while touching on different aspects of Gould's life and work. Ultimately, they show why Gould's writings and perspective are still relevant today, following his lead in using the natural history essay to articulate their view of evolutionary theory and its place in contemporary life. At once thought-provoking and entertaining, Macroevolutionaries is for all readers interested in paleontology, evolutionary biology, and Gould's literary and scientific legacy.

Introducing the theme of medicines as a mediator in chemistry teaching
This book aims to study how the subject of medicines is included in chemistry teaching in state schools in Ub獺-MG. A visit was made to the Senador Levindo Coelho state school and a questionnaire with open and closed questions was administered to teachers and students in the third year of secondary school. These questionnaires were used as tools to find out how teachers develop organic chemistry content and the students' prior knowledge of this content and its relationship to their daily lives. The second step was to analyze the contents of the textbooks and their relationship with the subject of medicines. Subsequently, the materials used in the development of this work were made up: questionnaires, directed studies and scripts for lectures and experiments in order to promote, in addition to contextualization, the students' curiosity in solving problems related to self-medication and the disposal of medicines. Knowledge was then applied through lectures covering the content of organic functions and involving the topic of medication in the identification of its compounds.
Yerba mate as a biosorbent for contaminants in water treatment
Among the technologies available for water recovery, one of the most widely used is adsorption, a process based on the ability of certain solids to remove soluble substances. For this reason, precursor materials with a high carbon content have been tested as adsorbents. The aim of this study was to test the adsorptive capacity of biomass obtained from consumed yerba mate waste, comparing activation by pyrolysis alone with activation with ZnCl2 and subsequent pyrolysis. The metals tested were Cu2+, Pb2+ and Ni2+, which can cause damage to health if ingested in high concentrations. It was observed that of the metals studied, copper is the most favourable to be removed from water, with almost 100% removal using activated carbon by pyrolysis alone. This process also showed the highest Freundlich constant (Kf) of 203.0 mg.g-1.
