Essential oils are simply the volatile oils of plants. These are concentrated liquids contain many terpenes, alkaloids and alcohols etc. Various compounds of essential oils have bioactive properties such as antimicrobial, anti-cancer, anti-diabetic, anti-viral and anti-fungal etc. This book describes the sources of essential oils, extraction and production method, characterizing tools, bioactivity, and various applications in the field of industries, daily usage, agriculture, health, and food.

The focus of Volume 2 is peptides and proteins. The organization emphasizes separation techniques, preparation protocols, and fundamentals of ionic gas-phase species of biological importance. This volume is divided into four sections: (1) experimental approaches and protocols, (2) sequence analysis, (3) other structural analyses, and (4) targeted applications.

Advanced analytical technologies offer flavor chemists the opportunity to explore and understand complex mixtures in great detail. This work covers three real-time mass spectrometric techniques applied to food-flavor assessments: APCI-MS, PTR-MS, and SIFT-MS. Chapters introduce each technique and review their implementation in key topics of food and flavor science. Latest applications and innovative new developments are outlined in several research chapters.

Large amounts of biomass residues are generated every year, and they can be utilized as one of the most abundant, cheap, and renewable resources on Earth. However, improper management allows these residues to become environmental hazards. This work presents research on how to utilize biomass derived from plant, animal, and industrial waste residues.

Chemistry serves a critical role in the fields of archaeology and art, from assisting in the reconstruction of humanity's past to the preservation of priceless works of art. Exploring the interface of chemistry, art, and archaeology within the chemistry curriculum can help students understand and engage in core chemistry concepts. Readers will appreciate the comprehensive description of tested pedagogical activities, laboratories, courses, and study abroad experiences at the intersection of chemistry, art, and archaeology.

Over the last 70 years, plastic usage has spread into nearly every corner of modern life and all geographies. For much of this time, plastics have been disposed of at the end of their first life. While recycling and reuse have increased, these have been limited by the need for clean, single-material streams as feedstock for mechanical recycling and the development status of advanced recycling technologies. By enabling the use of more mixed-waste streams, technologies will not only cut down on plastic waste landfilling, but also reduce greenhouse gas emissions.

Atkins' Physical Chemistry is widely acknowledged by students and lecturers around the globe to be the textbook of choice for studying physical chemistry. The exceptional quality of previous editions has been built upon to make the twelfth edition of Atkins' Physical Chemistry even more closely suited to the needs of both lecturers and students.

Analytical Chemistry is important and applied, experimental field of science that employs different instruments, and methods for the collection, separation, identification, and quantification of various organic, inorganic, and biological molecules. This interdisciplinary branch is based not only on chemistry but also on other disciplines such as biology, physics, pharmaceutical, and many areas of technology.

There has been an increasing rush of innovation in techniques to push the pressure limit higher in surface science experiments over the last twenty years. However, these new capabilities present practical difficulties in both performing the experiment and analyzing the data. This work explores the principles of vibrational, X-ray photoelectron, and X-ray absorption spectroscopies under ambient conditions and advanced applications of these techniques.

Transitioning to online learning, educators have been tasked with the difficult work of finding ways to reimagine content and deliver engaging courses that best serve each student's learning journey. This work offers data-supported strategies for online chemistry education with perspectives from students, teaching associates, teaching fellows, and academics. Chapters include case studies around teaching chemistry online, a review of options for chemistry labs in an online course, and guidance for adapting on-ground chemistry courses for the virtual environment in both asynchronous and synchronous delivery modalities.
