Process Development : Fine Chemicals from Grams to Kilograms
Process development bridges the gap between the laboratory synthesis of an organic compound and its industrial manufacture on a large scale.In this concise text the authors use real examples to show the problems which may be encountered in scaling up chemical syntheses and the ways in which these problems may be overcome.The major part of the book is devoted to genuine case histories from ICI/Zeneca Pharmaceuticals.Through a range of carefully chosen examples, the book explains how it is possible to synthesise multi-kilogram quantities of a new organic compound which have been made in the laboratory only on the milligram scale.A wide range of aliphatic, aromatic, and heterocyclic compounds is covered.The book will be of particular value to research chemists who are involved in the development phase of novel compounds and to advanced undergraduate and postgraduate students interested in the fine chemicals industry.

Programming Machine Learning : From Coding to Deep Learning
You've decided to tackle machine learning - because you're job hunting, embarking on a new project, or just think self-driving cars are cool.But where to start? It's easy to be intimidated, even as a software developer.The good news is that it doesn't have to be that hard.Master machine learning by writing code one line at a time, from simple learning programs all the way to a true deep learning system.Tackle the hard topics by breaking them down so they're easier to understand, and build your confidence by getting your hands dirty.Peel away the obscurities of machine learning, starting from scratch and going all the way to deep learning.Machine learning can be intimidating, with its reliance on math and algorithms that most programmers don't encounter in their regular work.Take a hands-on approach, writing the Python code yourself, without any libraries to obscure what's really going on.Iterate on your design, and add layers of complexity as you go.Build an image recognition application from scratch with supervised learning.Predict the future with linear regression. Dive into gradient descent, a fundamental algorithm that drives most of machine learning.Create perceptrons to classify data. Build neural networks to tackle more complex and sophisticated data sets.Train and refine those networks with backpropagation and batching.Layer the neural networks, eliminate overfitting, and add convolution to transform your neural network into a true deep learning system.Start from the beginning and code your way to machine learning mastery.What You Need: The examples in this book are written in Python, but don't worry if you don't know this language: you'll pick up all the Python you need very quickly.Apart from that, you'll only need your computer, and your code-adept brain.

What are PFAS chemicals?
PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been widely used in various industrial and consumer products since the 1940s. They are known for their water and oil repellent properties, and are commonly found in products such as non-stick cookware, food packaging, stain-resistant fabrics, and firefighting foams. PFAS chemicals are concerning because they are persistent in the environment, can accumulate in the human body, and have been linked to various health issues including cancer, immune system dysfunction, and reproductive problems. Due to their widespread use and potential health risks, there is growing concern and regulatory action to address PFAS contamination and exposure.

How are chemicals stored?
Chemicals are typically stored in a designated area that is well-ventilated, secure, and away from direct sunlight and heat sources. They should be organized and labeled properly to ensure easy identification and access. Additionally, chemicals should be stored in compatible groups to prevent any potential reactions or hazards. It is important to follow specific storage guidelines provided by the manufacturer and any relevant regulations to ensure safety and compliance.
-
What are BKS chemicals?
BKS chemicals are a type of chemical compound that are used in various industrial applications, including manufacturing, agriculture, and pharmaceuticals. These chemicals are often designed to have specific properties, such as being a catalyst, solvent, or reagent, and are used to facilitate or enhance chemical reactions. BKS chemicals can also be used in the production of various consumer products, such as cleaning agents, cosmetics, and food additives. Overall, BKS chemicals play a crucial role in many different industries and are essential for the production of a wide range of products.

The Secret Life of Chemicals
This book provides extensive information on the chemicals that inhabit our environment, our food, our water and our air and the impact that they may be having on human health.The author is a medical scientist, with training in the law. The book documents current understanding about pesticides in food, the plastics revolution, toxic metals, air, water and electronic waste pollutants, chemical exposure in the workplace, radiation pollutants, chemical exposure and hearing loss, how our bodies deal with chemicals, genetic variability and the risk of disease, the effect of chemicals on genes, mitochondria and the immune system and what we can do about it all. Industrialisation has resulted in many thousands of chemicals, which are being continuously developed and often escaping from where they are used into our human environment, without us really knowing enough about them.In high dosages or with continuous small dosage, the evidence suggests, that many of them couldinterfere with human health and some of them are known to be doing so. But for the vast majority, we are left wondering whether some could be responsible for some diseases the causes of which are inadequately understood. Every chapter is thoroughly reinforced with several pages of references from the peer-reviewed literature.
