Portland cement concrete, the most used manufactured material in the world, is a significant contributor to anthropogenic carbon dioxide (CO2) emissions. While strategies such as point-source CO2 capture, renewable fuels, alternative cements, and supplementary cementitious materials can yield substantial reductions in cement-related CO2 emissions, emerging biocement technologies based on the mechanisms of microbial biomineralization have the potential to radically transform the industry. In this work, we present a review and meta-analysis of the field of biomineralized building materials and their potential to improve the sustainability and durability of civil infrastructure. First, we review the mechanisms of microbial biomineralization, which underpin our discussion of current and emerging biomineralized material technologies and their applications within the construction industry. We conclude by highlighting the technical, economic, and environmental challenges that must be addressed before new, innovative biomineralized material technologies can scale beyond the laboratory.

This article reviews recent developments in small-scale mechanical property testing with some emphasis on intermediate (meso) length scales in complex microstructures and coated systems. The introduction summarizes size effects discovered from a century ago up to the recent explosion in micropillar testing that established many length scale effects in yielding and fracture. The bulk of the article deals with plasticity and fracture in polyphasic and microstructurally graded systems, including biomaterials, composites, and thermal protection systems, highlighting the use of in situ methods where mechanical tests are coupled to synchrotron X-ray scattering, electron backscattering, radiation damage, and digital image correlation. Expected final online publication date for the Annual Review of Materials Research, Volume 52 is July 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Recent decades have seen growing and widespread adoption of glass as an architectural material that can be used not only in window panes but also as facades, walls, and roofs. This is despite glass traditionally being considered a brittle material, not readily capable of handling the high loads required of architectural materials. Architectural glass has enabled the vaulted, transparent structures of many modern airport terminals and eye-catching buildings, such as the ubiquitous all-glass Apple Stores found around the world. Glass has enabled architects to expand their visions of buildings, using light and space to create wonderful new designs. As described in this review, these dramatic new possibilities for how glass is used in architecture have been the result of a convergence of many developments, including a better understanding of the fracture of glass, new processes for strengthening glass, confidence in large-scale finite element modeling of gravitational and wind loads, advances in the lamination of glass sheets, and the availability of ever larger individual sheets of float glass. The concurrent evolution of standards for the use of glass in buildings has also played a role in advancing the use of architectural glass. Advances in the architectural use of glass have their roots in the traditional uses and physical understanding of the properties of glass that have developed over hundreds of years.

Attempts to track material flows and the calculation of efficiency for material systems go hand in hand. Questions of where materials come from, where materials go to, and how much material is lost along the way are embedded in human societies. This article reviews material flows, their analysis, and progress toward material efficiency. We focus first on material flow analysis (MFA) and the three key tenants of any MFA: presentation of materials, visualization of the flow structure, and insight derived from analysis. Reviewing recent literature, we explore how each of these concepts is described, organized, and presented in MFA studies. We go on to show the role of MFA in material efficiency calculations and what-if scenario analysis for informed decision-making. We investigate the origins and motivations behind the material efficiency paradigm and the key efficiency strategies and practices developed in recent years and conclude by suggesting priorities for a future research agenda.

Hard solids with predominantly covalent–ionic bonding are finding rapidly increasing usage in many modern technologies. However, this class of solids is severely limited by their intrinsic brittleness—they break easily. It is in this context that a fundamental knowledge of brittle fracture mechanisms is of practical importance. This review covers the essential features of crack behavior in characteristically brittle solids, starting with fundamental physical and chemical models, with distinctions between equilibrium and kinetic states, stability and instability, and crack propagation and initiation. Means of imparting higher strength and toughness to otherwise brittle materials are then explored along with their pros and cons. Select technological areas where fracture properties constitute a vital facet of material function—windows and display panels, structural ceramics, biomaterials, layer structures, manufacturing, and nanomechanics—are then presented as illustrative case studies. The balance between factors such as strength and toughness, scaling and threshold effects, and crack containment and crack avoidance, as well as structure at the atomic and microstructural scales, emerge as critical factors in materials design.

The past decade was marked by significant advances in the development of severe plastic deformation (SPD) techniques to achieve new and superior properties in various materials. This review examines the achievements in these areas of study and explores promising trends in further research and development. SPD processing provides strong grain refinement at the nanoscale and produces very high dislocation and point defect densities as well as unusual phase transformations associated with particle dissolution, precipitation, or amorphization. Such SPD-induced nanostructural features strongly influence deformation and transport mechanisms and can substantially enhance the performance of advanced materials. Exploiting this knowledge, we discuss the concept of nanostructural design of metals and alloys for multifunctional properties such as high strength and electrical conductivity, superplasticity, increased radiation, and corrosion tolerance. Special emphasis is placed on advanced metallic biomaterials that promote innovative applications in medicine.

Recent advances in the field of diffusion in multiprincipal element systems are critically reviewed, with an emphasis on experimental as well as theoretical approaches to determining atomic mobilities (tracer diffusion coefficients) in chemically complex multicomponent systems. The newly elaborated and augmented pseudobinary and pseudoternary methods provide a rigorous framework to access tracer, intrinsic, and interdiffusion coefficients in alloys with an arbitrary number of components. Utilization of the novel tracer-interdiffusion couple method allows for a high-throughput determination of composition-dependent tracer diffusion coefficients. A combination of these approaches provides a unique experimental toolbox to access diffusivities of elements that do not have suitable tracers. The pair-exchange diffusion model, which gives a consistent definition of diffusion matrices without specifying a reference element, is highlighted. Density-functional theory–informed calculations of basic diffusion properties—asrequired for the generation of extensive mobility databases for technological applications—are also discussed.

Lithium garnet oxides are a family of fast-ion conductors with appreciable lithium ionic conductivity in the solid state, making them promising candidates as electrolytes for all-solid-state batteries. In their structures, lithium is partially (along with vacancy) distributed among more than one crystallographically distinct sites, just as with other fast-ion conductors. This disorder has a great influence on lithium's transport properties such as diffusivity and ionic conductivity. We review atomistic simulation studies in conjunction with complementary experimental investigations, which offer atomic-scale visualization of and insight into lithium transport phenomena in lithium garnet oxides.

This review focuses on the properties of reactive materials (RMs) that enable exothermic formation reactions and their application as local heat sources. We examine how the heat produced by these formation reactions can enable a range of useful functions including bonding, sealing, ignition, signaling, and built-in degradation. We begin by describing the chemistries, geometries, microstructures, and fabrication of RMs. We then explore the magnitude and measurement of their stored chemical energies and the rates and mechanisms by which the stored energy can be released to generate useful heat. The majority of the review focuses on how the released heat can be modeled and used to perform a range of functions. Expected final online publication date for the Annual Review of Materials Research, Volume 52 is July 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Strain glass is a new strain state discovered recently in ferroelastic systems that is characterized by nanoscale martensitic domains formed through a freezing transition. These nanodomains typically have mottled or tweed morphology depending on the elastic anisotropy of the system. Strain glass transition is a broadly smeared and high order–like transition, taking place within a wide temperature or stress range. It is accompanied by many unique properties, including linear superelasticity with high strength, low modulus, Invar and Elinvar anomalies, and large magnetostriction. In this review, we first discuss experimental characterization and testing that have led to the discovery of the strain glass transition and its unique properties. We then introduce theoretical models and computer simulations that have shed light on the origin and mechanisms underlying the unique characteristics and properties of strain glass transitions. Unresolved issues and challenges in strain glass study are also addressed. Strain glass transition can offer giant elastic strain and ultralow elastic modulus by well-controlled reversible structural phase transformations through defect engineering.
