Biology, Chemistry and Physics are the core disciplines upon which our scientific understanding and teaching are based. Physics underpins our understanding of the real world with a mathematical framework based on fundamental laws; Chemistry derives knowledge of the composition, properties and behaviour of matter and materials; while Biology investigates the living world, deriving general principles and obtaining detailed insight into the way in which units of life relate to one another. In this module, you will be introduced to the key concepts of each discipline, while recognising the inter-reliance of each in understanding the Natural World.

The module aims to provide you with a detailed understanding of the core concepts surrounding Biology, Chemistry and Physics. The intention is that you will complete the module with a breadth of understanding sufficient to allow you to undertake core second year modules in each Discipline. Specifically:

Biology: You will be introduced to the concepts of biological diversity, evolution, the genetic basis of life and the boundaries that encompass biological systems. You will then explore the fundamental principles underlying these systems, at the level of the biochemical reaction, the cell, the tissue, the entity, the population and the environment. Specific examples will be used to reinforce your understanding and to relate the chemical and physical principles taught in the other areas of the module, to the biological world.

Chemistry: We will teach you how energy quantisation leads to the atomic and molecular orbitals that govern the physicochemical properties of substances and how to apply this knowledge in rationalising chemical reactivity and bonding. We will show you how to apply the laws of thermodynamics to predict the position of chemical equilibrium and how theories of reaction kinetics are used to interpret experimental data for reaction rates. We will teach you the nomenclature, structural representations and reaction mechanisms of organic chemistry, showing you how to apply this knowledge in chemical synthesis.

Physics: We will teach you how to make quantitative predictions about the physical world by combining physical principles to build mathematical models. You will be introduced to fundamental physical principles and some standard models of physics, including models for atoms, solids, liquids and gases, and light and sound. You will be guided in how to apply the principles of physics in new situations and manipulate mathematical formulae to build quantitative physical models. Your problem-solving strategies and strategies for identifying and remedying missing knowledge will be developed.

Biological Content Summary

We will begin by addressing the concepts of space (boundaries), time, quantities and relationships of entities within the biological world, providing the framework upon which we build your understanding. We will then take a "bottom up" approach; building your knowledge of the fundamental building blocks of life leading to biological macromolecules. We then take you on a tour of the cell, before explaining the concepts of energy storage and release in animals and plants. Next, we will show you how those principles lead to the generation of life, and the diversity within. This takes us to the realm of the gene; the chromosomal and molecular basis of inheritance and how that information is expressed in the form of protein. With the building blocks of life in place, we switch to focusing on mechanisms of evolution, the tree of life, diversity of biological form and the major clades of life. We continue to work upwards to the level of multicellular plant and animal life, organ endocrine and reproductive systems before finally taking a look at ecosystems and their relationship to the natural world.

Chemistry Content Summary

We shall begin by discussing the origin of atomic orbitals, their shape, the associated quantum numbers and the rules governing the filling of orbitals with electrons, before seeing how this knowledge explains chemical properties and reactivity. We shall then see how the linear combination of atomic orbitals (LCAO) is used to construct molecular orbitals and so to explain the bonding and associated properties, including aspects of their bond vibration as evidenced by infrared spectroscopy, of some simple molecules. The course then turns to consider reacting mixtures of chemical substances, showing how thermodynamics governs the position of reaction equilibrium and outlining the theories of reaction kinetics used to interpret measurements of chemical reaction rate in terms of a rate law and a reaction mechanism. The underlying mathematics is considered in some detail and the overlap with physics (e.g. the Maxwell-Boltzmann distribution for speeds of gas molecules) and biology (e.g. enzyme kinetics) is highlighted. With these enabling concepts in place, we shall then turn to structure and reactivity of organic molecules, pertinent in particular to the chemistry and biology of living systems. Prefaced by a discussion of orbital hybridisation and bonding in carbon, and including the analytical elements of mass spectrometry and of nuclear-magnetic resonance (NMR) and infrared spectroscopies, we shall explain how organic molecules are named and represented, how different functional groups impart different reactivity and how the main reaction types (addition, substitution and elimination) occur in mechanistic terms. This is the central synthetic framework for everything from the elucidation of biosynthetic pathways in nature, to designing new molecules and materials for use in all branches of science.

The precise control of reaction outcomes to achieve materials with well-defined features is a main endeavor in the development of inorganic materials. Confining reaction within a confined space, such as nanoreactor, is an extremely promising methodology which allows to ensure control over the final properties of the material. An effective room temperature inverse miniemulsion approach was developed for the controlled synthesis of non-doped and Eu3+-doped calcium molybdate crystalline nanophosphors. The advantages and the efficiency of confined space in terms of nanoparticles features like size, shape and functional properties are highlighted by systematically comparing miniemulsion products with calcium molybdate particles obtained without confinement from a typical batch synthesis. A relevant beneficial impact of space confinement by miniemulsion nanodroplets is observed on the control of size and shape of the final nanoparticles, resulting in 12 nm spherical nanoparticles with narrow size distribution, as compared to the 58 nm irregularly shaped and aggregated particles from the batch approach (assessed by TEM analysis). Further considerable effects of the confined space for the miniemulsion samples are found on the doping effectiveness, leading to a more homogeneous distribution of the Eu3+ ions into the molybdate host matrix, without segregation (assessed by PXRD, XAS, ICP-MS, photoluminescence studies). These findings are finally related to the photoluminescence properties, which are evidenced to be closely dependent on the Eu3+ content in the miniemulsion samples, whereas no relationship is evidenced for the batch samples. All these results are attributed to the uniform and controlled crystallization process occurring inside each miniemulsion nanodroplet, as opposed to the uncontrolled nucleation and growth observed in the classic non-confined approach.
