The Globalization of Clean Energy Technology
Authors: Gallagher Kelly Sims 
Published: March 2019

An examination of barriers that impede and incentives that motivate the global development and deployment of cleaner energy technologies, with case studies from China.
The development and deployment of cleaner energy technologies have become globalized phenomena. Yet despite the fact that energy-related goods account for more than ten percent of international trade, policy makers, academics, and the business community perceive barriers to the global diffusion of these emerging technologies. Experts point to problems including intellectual property concerns, trade barriers, and developing countries' limited access to technology and funding. In this book, Kelly Gallagher uses analysis and case studies from China's solar photovoltaic, gas turbine, advanced battery, and coal gasification industries to examine both barriers and incentives in clean energy technology transfer.
Gallagher finds that the barriers are not as daunting as many assume; these technologies already cross borders through foreign direct investment, licensing, joint R&D, and other channels. She shows that intellectual property infringement is not as widespread as business leaders fear and can be managed, and that firms in developing countries show considerable resourcefulness in acquiring technology legally. She finds that financing does present an obstacle, especially when new cleaner technologies compete with entrenched, polluting, and often government-subsidized traditional technologies. But the biggest single barrier, she finds, is the failure of government to provide sensible policy incentives. The case studies show how government, through market-formation policy, can unleash global market forces. Gallagher's findings have theoretical significance as well; she proposes a new model of global technology diffusion that casts doubt on aspects of technology transfer theory.
Peripheral Vision
Authors: Patterson Zabet 
Published: March 2019

How the S-C 4020—a mainframe peripheral intended to produce scientific visualizations—shaped a series of early computer art projects that emerged from Bell Labs.
In 1959, the electronics manufacturer Stromberg-Carlson produced the S-C 4020, a device that allowed mainframe computers to present and preserve images. In the mainframe era, the output of text and image was quite literally peripheral; the S-C 4020—a strange and elaborate apparatus, with a cathode ray screen, a tape deck, a buffer unit, a film camera, and a photo-paper camera—produced most of the computer graphics of the late 1950s and early 1960s. At Bell Laboratories in Murray Hill, New Jersey, the S-C 4020 became a crucial part of ongoing encounters among art, science, and technology. In this book, Zabet Patterson examines the extraordinary uses to which the Bell Labs SC-2040 was put between 1961 and 1972, exploring a series of early computer art projects shaped by the special computational affordances of the S-C 4020.
The S-C 4020 produced tabular data, graph plotting and design drawings, grid projections, and drawings of axes and vectors; it made previously impossible visualizations possible. Among the works Patterson describes are E. E. Zajac's short film of an orbiting satellite, which drew on the machine's graphic capacities as well as the mainframe's calculations; a groundbreaking exhibit of “computer generated pictures” by Béla Julesz and Michael Noll, two scientists interested in visualization; animations by Kenneth Knowlton and the Bell Labs artist-in-residence Stan VanDerBeek; and Lillian Schwartz's “cybernetic” film Pixillation.
Arguing for the centrality of a peripheral, Patterson makes a case for considering computational systems not simply as machines but in their cultural and historical context.

Published: March 2019

Objective(s)To fully understand the dynamics of Intimate Partner Violence (IPV) it is necessary to understand the role of personality. The current understanding of which personality characteristics are associated with IPV victimization is, however, far from comprehensive. Given this gap in the literature, our objective was to examine the associations between the dimensions of the psychobiological model of personality and psychopathological symptoms in women who had experienced IPV.MethodsUsing a case-control design, a group of women who had experienced IPV and who were living in shelters (n= 50) were compared to a group of control women who had not experienced IPV (n= 50). All women completed the Temperament and Character Inventory–Revised and the Brief Symptom Inventory.ResultsVictims of IPV showed significantly higher levels of Harm Avoidance and Self-Transcendence, and lower levels of Reward Dependence and Self-Directedness, than the non-IPV control group. Victims of IPV also reported elevated levels of psychopathological symptoms. Personality dimensions showed a broadly consistent pattern of associations across different psychopathological symptoms. A regression analysis indicated that Novelty Seeking was negatively associated with psychopathological symptoms in victims of IPV, but not significantly associated in non-victims.ConclusionsThe study highlights the important role of Harm Avoidance and Self-Directedness for understanding psychopathological symptoms. Novelty Seeking appears to play an important role in the expression of individuals’ experiences of IPV. These results have important implications for research and practice, particularly the development and implementation of interventions.

The vegetation and the afforestation of agricultural land non-forest represent a potential increase in carbon stocks which could, under certain conditions and within certain limits, compensate part of the emissions resulting from the use of fossil fuels and deforestations. Quantification of stocks of biomass and carbon dioxide contained in agroforestry systems has become an international priority within the framework of the implementation of REDD+ mechanism. Estimates of stocks of carbon in woody biomass, dead organic matter, belowground biomass, litter, herbaceous and lianas plant biomass were incorporated in allometric equation based on non-destructive method. The total carbon stock evaluated in the parkland of Tectona grandis was 207.34 ton/3ha out of which woody biomass accounted for 130.19 ton/3ha belowground biomass (40.4 ton/3ha), dead organic matter (22.85 ton/3ha), litter (9.09 ton/3ha), herbaceous plant biomass (2.28 ton/3ha) and lianas (2.53 ton/3ha). The aboveground biomass therefore contributed approximately 62.80 % of the total stock of carbon assessed. This show the considerable contribution of Tectona grandis parkland to climate change mitigation in Cameroon.

AbstractThe stiffening of the extracellular matrix (ECM) with age hinders muscle regeneration by causing intrinsic muscle stem cell (MuSC) dysfunction through a poorly understood mechanism. Here, the study aims to study those age‐related molecular changes in the differentiation of MuSCs due to age and/or stiffness. Hence, young and aged MuSCs are seeded onto substrates engineered to mimic a soft and stiff ECM microenvironment to study those molecular changes using single‐cell RNA sequencing (scRNA). The trajectory of scRNA data of the MuSCs under four different conditions undergoing differentiation is analyzed as well as the active molecular pathways and transcription factors driving those differentiation fates. Data revealed the presence of a branching point within the trajectory leading to the emergence of an age‐related fibroblastic population characterized by activation of the TNF‐related apoptosis‐inducing ligand (TRAIL) pathway, which is significantly activated in aged cells cultured on stiff substrates. Next, using the collagen cross‐linking inhibitor β‐aminopropionitrile (BAPN) in vivo, the study elucidates stiffness changes on TRAIL downstream apoptotic targets (caspase 8 and caspase 3) using immunostaining. TRAIL activity is significantly inhibited by BAPN in aged animals, indicating a complex mechanism of age‐related declines in muscle function through inflammatory and apoptotic mediators.

AbstractThe assembly of synthetic modules into user‐defined hydrogels for cell culture and clinical applications carries significant advantages over naturally derived materials. Modularity is exploited in synthetic‐polymer‐based hydrogels to alter their physical properties, and spatiotemporally incorporate signaling peptides and growth factors. By contrast, the design of self‐assembling peptide hydrogels has focused largely on assessing cellular responses to unmodified hydrogels and introducing small cell‐adhesive ligands. In short, the modularity of peptide hydrogels is yet to be fully exploited. Previously, hydrogelating self‐assembling fibers (hSAFs) are reported in which two de novo designed α‐helical peptides form gels when mixed. Here, rational peptide design and engineering are used to alter the elastic properties of these hydrogels, to introduce adhesion peptides and growth factors, and to spatially pattern proteins within them. Analysis of the viability and morphology of primary rat neurons cultured on these hydrogels indicates that the modularity of the hSAF system provides a flexible platform for manipulating cell behavior, with potential future applications for modeling natural systems in vitro and regenerative medicine in vivo.

Published: November 2024

AbstractDirect regeneration of electrode materials has been in the spotlight due to its potential resource recovery and environmental benefits, especially for LiNixCoyMnzO2 (NCM) cathode materials. Yet, prior studies have predominantly emphasized innovating regeneration methods, overlooking the intrinsic defects of spent NCM and their effects in the regeneration process. This study proposes a mechanism aimed at facilitating lithiation regeneration by modulating the surface defects of spent NCM. The generation of oxygen defects in degraded NCM intensifies the adsorption of lithium source, effectively reducing the energy barrier for Li+ migration from surface to bulk. Simultaneously, mechanical energy is employed to alter the local thermodynamic state to provide a driving force for lithium migration, allowing it to undergo a prelithiation reaction before roasting. The temperature range in which the phase transition occurs during the roasting process becomes more concentrated. This contributes to increasing opportunities for lithium insertion and accelerates the repair of crystal structure, resulting in favorable properties of regenerated materials. This strategy innovatively exploits the inherent defects of spent NCM, proposes the critical role of synergistically regulating defect kinetic and thermodynamic features in facilitating regeneration, providing a unique perspective for the design of direct NCM regeneration technology.

AbstractFlexible and robust memristors with controllable resistance‐switching characteristics are important to neuromorphic computing. However, the nanomaterials‐based, solution‐processed resistance switching layer usually has poor reliability and tunability due to uneven morphology and invariable surface properties. Herein, phosphorylated graphene nanoflakes (phos‐GPs) are synthesized for high‐performance solution‐processed flexible memristors. In situ conductive atomic force microscopy reveals that the tightly stacked uniform nanoflakes and modified phosphorate groups jointly reduce the formation barrier of the conductive filaments. Furthermore, phosphorylation gives rise to surface silver ion coordination leading to enhanced radial growth of the conductive filaments. The memristor shows volatile characteristics in the Ag/phos‐GPs/ITO architecture and exhibits non‐volatile properties in the Ag/Ag+‐(phos‐GPs)/ITO structure. Both types of memristors display consistent I‐‐V curves during long‐term cycling and under repetitive mechanical bending, in addition to excellent synaptic plasticity. Moreover, ultrasmall nonlinearity is observed from non‐volatile long‐term synaptic potentiation and depression. By utilizing the tunable artificial synapses, the processes of memory‐forgetting and re‐recognition are simulated, and the image recognition tasks are accomplished by the artificial neural networks.

Published: November 2024

AbstractZinc‐ion batteries possess operation safety, high energy density, production flexibility and affordability, making them attractive for scalable energy storage. While Zn anodes face significant challenges from rampant dendrite growth and electrolyte‐related side‐reactions in a complex interfacial microenvironment. The growing interfacial resistance further degrades the battery performance. An integrated anode interfacial design is reported to regulate simultaneously the Zn2+ flux and interfacial resistance through in situ confinement growth of Zn2+ sieve, that is, 2D CuBDC metal–organic framework in mesoporous carbonaceous host. CuBDC with sub‐nanometer channels is selected for efficient dehydration and directional Zn2+ flux transport, and lowering the nucleation barrier by zincophilic Cu(II) and N sites. Conductive meso‐carbon reduces the interfacial resistance and blocks the interfacial side‐reactions. Resultantly, the modified Zn anodes demonstrate improved cycling stability with lower voltage polarization, supported by operando optical microscopy and ex situ analysis. This work provides a feasible strategy improving aqueous Zn anodes and new interfacial insights on designing advancing zinc batteries.

AbstractEnhancing the thermal decomposition efficiency and safety of ammonium perchlorate (AP) is of far‐reaching significance in composite propellants. Most catalysts act well on the thermal decomposition of AP, however, synergistically achievements of fastened decomposition and improved mechanical safety are still in challenge. Herein, neutral red (NR) is selected from typical dyes through theoretical calculations, acting as an organic decoration of AP crystal with improved performances. Among the four organic dyes, NR demonstrated the highest adsorption energy and evident charge transfer at the interface. Following preparations through a freeze‐drying technique obtained a quasi‐homogeneous energetic composite (NR‐AP‐5%). The large interaction force between NR and AP promoted the rupture of chemical bonds between Cl and O as proved by TG‐MS, showing excellent energy‐release performance with the decreased exothermic peak from 437.0 to 355.5 °C. Correspondingly, the activation energy is reduced from 213.59 to 107.72 kJ mol−1, with largely increased heat release from 447.29 to 1014.86 J g−1. In addition, the inert decoration of NR endowed considerable advances in the safety performances of AP, achieving remarkably improved impact and friction sensitivity of 35 J and 288 N, respectively. This unique assembly structure provides a novel strategy to achieve high‐effective catalysis for functional propellants.
Enabling One‐Step De‐Sodiation of Na4MnV(PO4)3 Cathode via Regulating Coordination Environment for High‐Power and Long‐Lasting Sodium‐Ion Batteries

Published: November 2024

AbstractNa4MnV(PO4)3 (NMVP) is considered as a promising cathode candidate for sodium‐ion batteries (SIBs) because it possesses a higher voltage plateau of 3.6 V (Mn3+/Mn2+) besides the voltage plateau of 3.4 V (V4+/V3+), lower cost, and environmental benign compared to Na3V2(PO4)3. However, such cathode still suffers from sluggish intrinsic Na+ diffusion kinetics and the Jahn‐Teller distortion of Mn3+, leading to low capacity and poor cycling performance. Particularly, the second‐step Na+ de‐sodiation in NMVP is the rate‐determining step owing to a lower chemical diffusion coefficient with one order of magnitude than that of the first‐step counterpart. To address these issues, a coordination environment regulation strategy is reported to develop a one‐step de‐sodiation NMVP cathode via introducing Zr4+ and K+/Ca2+ into Mn and Na sites, respectively. Based on theoretical calculations and electrochemical evaluation, the obtained Na3.3K0.1Ca0.1Mn0.8VZr0.2(PO4)3 exhibits much enhanced Na+ diffusion and efficiently inhibits the Jahn‐Teller distortion. Importantly, such modification significantly facilitates the second‐step Na+ diffusion of NMVP, realizing one‐step de‐sodiation. When employed as a cathode for SIBs, such cathode shows a specific capacity of 73 mAh g−1 (15 C), and capacity retentions of 92.7% after 3000 cycles (at 10 C, room temperature), and 72.6% after 1000 cycles (1 C, 50 °C).

Published: November 2024

AbstractAddressing the urgent need for effective fracture treatments, this study investigates the efficacy of a 3D bioprinted biomimetic hydrogel, enriched with bone marrow mesenchymal stem cells (BMSCs) and targeted hypoxia‐inducible factor 1 alpha (Hif1a) gene activation, in enhancing fracture healing. A photocross‐linkable bioink, gelatin methacryloyl bone matrix anhydride (GBMA) is developed, and selected its 5% concentration for bioink formulation. Rat BMSCs are isolated and combined with GBMA to create the GBMA@BMSCs bioink. This bioink is then used in 3D bioprinting to fabricate a hydrogel for application in a rat femoral fracture model. Through transcriptome sequencing, WGCNA, and Venn analysis, the hypoxia‐inducible factor Hif1a is identified as a critical gene in the fracture healing process. In vitro studies showed that Hif1a promoted BMSC proliferation, chondrogenic differentiation, and cartilage matrix stability. The in vivo application of the GBMA@BMSCs hydrogel with Hif1a overexpression significantly accelerated fracture healing, evidenced by early and enhanced cartilage callus formation. The study demonstrates that 3D bioprinting of GBMA@BMSCs hydrogel, particularly with Hif1a‐enhanced BMSCs, offers a promising approach for rapid and effective fracture repair.

AbstractThe clearance of minimal residual disease (MRD) after breast cancer surgery is crucial for inhibiting metastasis and recurrence. However, the most promising biomarker‐activated fluorescence imaging strategies encounter accessibility issues of the delivered sensors to cytoplasmic targets. Herein, a flower‐like composite nanosensor with photoacoustic (PA) effect‐enhanced lysosomal escape and cytoplasmic marker‐activated fluorescence is developed to address this challenge. Specifically, the incorporation of Co2+ into the synthesis of 2D Zn2+‐derived metal–organic frameworks enabled rapid dopamine polymerization and deposition. Subsequently, the composite nanoflower (FHN), characterized by an average size of ≈80 nm and petal thickness of ≈6 nm, is formed through the sealing of micropores and simultaneous cross‐linking of nanosheets. The pronounced reduction in thermal conductivity of FHN, and superposition of interpetal thermal fields under a pulsed laser (PL), lead to enhanced PA effect and membrane permeability. Thereby, nanosensors efficiently escape from lysosomes resulting in synergistic fluorescence activation by dual‐factors (ATP, miRNA‐21) and DNA probes installed on FHN. A subsequently high tumor‐to‐normal tissue signal ratio (TNR) of 17.4 lead to precise guidance of NIR irradiation for efficient MRD eradication and recurrence inhibition. This study provides a new approach for high‐contrast identification and precise ablation of MRD based on the synergistic response of endogenous and exogenous factors.
