Volume 41 of Reviews in Mineralogy and Geochemistry introduces to the field of high-temperature and high-pressure crystal chemistry, both as a guide to the dramatically improved techniques and as a summary of the voluminous crystal chemical literature on minerals at high temperature and pressure. The three parts of the book introduces crystal chemical considerations of special relevance to non-ambient crystallographic studies, reviews the temperature- and pressure-variation of structures in major mineral groups and presents experimental techniques for high-temperature and high-pressure studies of single crystals and polycrystalline samples as well as special considerations relating to diffractometry on samples at non-ambient conditions.

Improved housing conditions can save lives, prevent disease, increase quality of life, reduce poverty, and help mitigate climate change. Housing is becoming increasingly important to health in light of urban growth, ageing populations and climate change. The WHO Housing and health guidelines bring together the most recent evidence to provide practical recommendations to reduce the health burden due to unsafe and substandard housing. Based on newly commissioned systematic reviews, the guidelines provide recommendations relevant to inadequate living space (crowding), low and high indoor temperatures, injury hazards in the home, and accessibility of housing for people with functional impairments. In addition, the guidelines identify and summarize existing WHO guidelines and recommendations related to housing, with respect to water quality, air quality, neighbourhood noise, asbestos, lead, tobacco smoke and radon. The guidelines take a comprehensive, intersectoral perspective on the issue of housing and health and highlight co-benefits of interventions addressing several risk factors at the same time. The WHO Housing and health guidelines aim at informing housing policies and regulations at the national, regional and local level and are further relevant in the daily activities of implementing actors who are directly involved in the construction, maintenance and demolition of housing in ways that influence human health and safety. The guidelines therefore emphasize the importance of collaboration between the health and other sectors and joint efforts across all government levels to promote healthy housing. The guidelines' implementation at country-level will in particular contribute to the achievement of the Sustainable Development Goals on health (SDG 3) and sustainable cities (SDG 11). WHO will support Member States in adapting the guidelines to national contexts and priorities to ensure safe and healthy housing for all.

Within the last two decades, the experimental technology for the study of high temperature solid-vapor and liquid-vapor equilibria has mushroomed so fast that· both academic and industrial research ers desirous of working in this field -- be they physical chemists, metallurgists, ceramists, petrologists, crystal chemists, or mem bers of any of the several branches of materials science -- find themselves in the situation that in order to learn the art of the latest techniques, a period of apprenticeship or residency needs be spent at an institution or laboratory currently engaged in this type of solid-vapor or liquid-vapor research. The tech niques for control of the vapor phase at total pressures of one atmosphere or greater have not been well defined in the literature. Therefore, the purpose of this volume will be to serve as a labora tory manual for the control, calibration, and measurement of high temperature-high pressure equilibria. The avowed aims of this treatment of experimental techniques are: (1) to give, in terms understandable at the graduate student level, the laboratory procedures necessary to the design and utilization of good experimental technique, (2) to list the limitations, dangers, and technical pitfalls inherent or intrinsic to the described techniques, (3) to give theory and specific data only where they are essential to the experimental design, (4) to give with each chapter references that are extensive enough to serve as a bibliography of the state-of-the-art of technique development within the last decade.
