Single-Crystalline Perovskite Nanowire Arrays for Stable X-ray Scintillators with Micrometer Spatial Resolution

X-ray scintillation detectors based on metal halide perovskites have shown excellent light yield, but they mostly target applications with spatial resolution at the tens of micrometers level. Here, we use a one-step solution method to grow arrays of 15-μm-long single-crystalline CsPbBr3 nanowires (NWs) in an AAO (anodized aluminum oxide) membrane template, with nanowire diameters ranging from 30 t

Urban Energy Landscapes and the Rise of Heat Networks in the United Kingdom

In the past decade, district heat networks have emerged as a key strategy for the UK government to achieve its 2050 decarbonization targets. Reports and analyses have focused on the technical and economic challenges of introducing networked heat provision in a country where this is a relatively novel energy service. Meanwhile, there has been little emphasis on the spatial and physical aspects of h

Miaolingian (Cambrian) trilobite biostratigraphy and carbon isotope chemostratigraphy in the Tingskullen drill core, Öland, Sweden

The Cambrian succession of the Tingskullen drill core from northern Öland comprises Cambrian Series 2 and Miaolingian (Wuliuan Stage) siliciclastic strata. The major portion of the succession is represented by the Miaolingian Borgholm Formation, which, in ascending order, is subdivided into the Mossberga, Bårstad and Äleklinta members. The Äleklinta Member is barren of body fossils, whereas the Mo

Sustainable architecture in context : STS and design thinking

There has been little emphasis in STS scholarship to date on the design of the built environment. This paper attempts to address this oversight by examining alternative design practices in the growing field of sustainable architecture. We propose a geohistorical framework that includes three design dispositions—context-bound, context-free, and context-rich—and illustrate each with a prominent sust

The ecosystem of expertise : complementary knowledges for sustainable development

This article critically examines the approach of technical experts, including engineers, natural scientists, architects, planners, and other practitioners, who are attempting to create more sustainable forms of economic development, environmental protection, and social equity. The authors identify four principal characteristics of expertise–ontological assumptions, epistemological approaches, powe

University campuses as testbeds of smart urban innovation

In this chapter, the authors begin by interpreting smart urban development as a mode of urban experimentation where Information & Communication Technology (ICT) is being implemented to fundamentally alter the operation of cities. They focus on the role of university campuses in situating smart urban development. By drawing on literatures on urban laboratories and experimentation as well as uni

Smart goes green : digitalising environmental agendas in Bristol and Manchester

The smart city is increasingly described as an emergent and soon to be dominant urban development paradigm. This chapter examines the translation of smart urban development to two British cities with noted environmental agendas: Bristol and Manchester. Both cities exemplify the 'actually existing smart city', with a particular emphasis on the green or environmental aspects of smart technologies. T

Innovating for an ageing society : insights from two Japanese smart cities

Smart cities are enthusiastically promoted around the world by industry and governments alike as a desirable means to achieve urban sustainability. This chapter contributes empirical evidence on how projects reflecting qualities of a Smart City 2.0 model can play out on the ground. It examines two Japanese smart cities addressing the interconnected challenges of an ageing society and preventative

Introduction : situating smart cities

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book illustrates how urban innovation is being negotiated and interpreted in a wide range of contexts, while also raising more fundamental questions about the rapidly evolving relationship between society and information and communication technologies (ICT). It describes how smart urba

Conclusions : the long and unsettled future of smart cities

Smart urbanisation is neither universal, apolitical nor straightforward. Many advocates of smart urbanisation suggest that the fully connected and digitalised future is just around the corner. Negotiations over technological choices, financial models, the role of technical experts and related issues resonate with today's smart cities debates. Contemporary smart city interventions continue to be pa

Afterword : planning and the non-modern city

Cities are messy, planning is messy. Things do not come together as nicely as we would like; they do not necessarily add up. It is one thing to say that cities are multifaceted and complex and quite another to engage with and study this complexity and make sense of it. STS provides a way to interpret and engage with urban messiness without oversimplifying and missing out on the essence of cities.

Community housing retrofit in the UK and the civics of energy consumption

The existing housing stock in the UK will make a significant contribution to national carbon emissions for many decades to come. Existing houses present a significant challenge to systemic upgrades because they are influenced by a disparate set of regulations, incentives, and stakeholders. Unlike the new build industry, there is no single set of standards to regulate and steer the energy performan
