    Among the strategies for reducing the negative effects on the environment affected by the uncontrolled consumption and low potential for the recovery of conventional plastics, the synthesis of new biodegradable and recyclable plastics represents one of the most promising methods for minimizing the negative effects of conventional non-biodegradable plastics. The spectrum of existing biodegradable materials is still very narrow. Therefore, to achieve greater applicability, research is being carried out on biodegradable polymer mixtures, the synthesis of new polymers, and the incorporation of new stabilizers for thermal degradation, alongside the use of other additives such as antibacterials or new and more sustainable plasticizers. Some studies analyze direct applications, such as shape memory foams, new cartilage implants, drug release, etc. The reader can find several studies on the degradation of biodegradable polymers under composting conditions. However, novel bacteria that degrade polymers considered non-biodegradable in other, unusual conditions (such as conditions of high salinity) are also presented.

    This thesis investigates the detection efficiency of field-resolved measurements of ultrashort mid-infrared waves via electro-optic sampling for the first time. Employing high-power gate pulses and phase-matched upconversion in thick nonlinear crystals, unprecedented efficiencies are achieved for octave-spanning fields in this wavelength range. In combination with state-of-the art, high-power, ultrashort mid-infrared sources, this allows to demonstrate a new regime of linear detection dynamic range for field strengths from mV/cm to MV/cm-levels. These results crucially contribute to the development of field-resolved spectrometers for early disease detection, as fundamental vibrational modes of (bio-)molecules lie in the investigated spectral range.The results are discussed and compared with previous sensitivity records for electric-field measurements and reference is made to related implementations of the described characterization technique. Including a detailed theoretical description and simulation results, the work elucidates crucial scaling laws, characteristics and limitations. The thesis will thus serve as an educational introduction to the topic of field-resolved measurements using electro-optic sampling, giving detailed instructions on simulations and experimental implementations. At the same time, it showcases the state-of-the-art in terms of detection sensitivity for characterizing mid-infrared waves.

    Organic compounds are, at the most basic level, compounds that contain carbon and hydrogen. These compounds are called organic because they were once believed to have been derived from living things, but that is not necessarily the case. The organic compound is a large class of chemical compounds in which one or more carbon atoms are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. Some examples of organic compounds are carbohydrates, fats (lipids), proteins, and nucleic acids, which are the basis for the molecules of life. "Classification & Analysis of Organic Compounds" is a comprehensive book that describes basic concepts about the classification of organic compounds and how to do analysis of an organic compound. The book includes crystallization techniques, concepts of photochemistry, the chemistry of volatile organic compounds, electrochemistry, medicinal organic chemistry, enzymes, and their action. This book includes concepts about intermolecular interactions and their significance in detail.

    The thesis presents a systematic study of the Mpemba effect in a colloidal system with a micron-sized particle diffusing in a water bath. While the Mpemba effect, where a system's thermal relaxation time is a non-monotonic function of the initial temperature, has been observed in water since Aristotle's era, the underlying mechanism of the effect is still unknown. Recent studies indicate that the effect is not limited to water and has been studied both experimentally and numerically in a wide variety of systems. By carefully designing a double-well potential using feedback-based optical tweezers, the author demonstrates that an initially hot system can sometimes cool faster than an initially warm system. The author also presents the first observation in any system of another counterintuitive effect-the inverse Mpemba effect-where the colder of the two samples reaches the thermal equilibrium at a hot temperature first. The results for both the observations agree with theoretical predictions based on the Fokker-Planck equation. The experiments reveal that, for carefully chosen conditions, a strong version of both of the effects are observed where a system can relax to the bath temperature exponentially faster than under typical conditions.

    Pavement materials such as asphalt mixtures, granular aggregates, and soils exhibit complex material properties and engineering performance under external loading and environmental conditions. For instance, the asphalt mixture shows highly nonlinear viscoelastic and viscoplastic properties at high temperatures, and it presents fatigue cracking damage and fracture properties at intermediate or low temperatures. Constitutive models based on mechanics theories have been the kernel of performance prediction of pavement infrastructures and materials. They lay down a solid foundation for material selection, design, pavement structural evaluation and maintenance decisions. Advances in mechanics modeling and associated experimental testing for pavement infrastructures and construction materials are emerging constantly, such as nonlinear viscoelasticity, viscoplasticity, fracture, and damage mechanics models. Meanwhile, various numerical modeling technologies are being developed and implemented to solve the multiscale and multiphysical equations. Examples include finite element, discrete element, and micromechanics or molecular dynamics simulations at different dimensions and scales. This reprint provides a unique platform, presenting novel studies and new discoveries in the areas of mechanics, numerical modeling and experimental testing of pavement infrastructures and materials.

    His life thrown into chaos by the death of his father in his youth, Linus Pauling persevered through an impoverished childhood to become one of the great scientists and humanitarians of the 20th century. In a stunningly original examination of the two-time Nobel Laureate, Oregon State University archivist Chris Petersen touches upon the major eras of Pauling's life and dials into specific episodes, themes, accomplishments, and failures at a level of detail that has not been put forth elsewhere. Topics exclusively covered here include Pauling's generative process as author of the groundbreaking text The Nature of the Chemical Bond; the colorful history of the Linus Pauling Institute; his symbiotic relationship with the W H Freeman & Co. publishing house; two entirely separate clashes with the United States Senate and the Soviet Academy of Science; and the story of his brilliant and troubled son Peter. Interspersed throughout the book are light pieces that narrate humorous moments in Pauling's life and other vignettes that lend insight into his seemingly maverick personality. The culmination of 15 years of research, Visions of Linus Pauling is a magisterial piece of work, equivalent to previously unseen footage of a blockbuster movie.The Pauling Blog: https: //paulingblog.wordpress.com/2022/11/03/we-wrote-a-book/
