Giant energy-storage density with ultrahigh efficiency in lead-free relaxors via high-entropy design
Authors: Chen, L.; Deng, S.; Liu, H.; Wu, J.; Qi, H.
Journal: Nature Communications (2022)

AbstractNext-generation advanced high/pulsed power capacitors rely heavily on dielectric ceramics with high energy storage performance. However, thus far, the huge challenge of realizing ultrahigh recoverable energy storage density (Wrec) accompanied by ultrahigh efficiency (η) still existed and has become a key bottleneck restricting the development of dielectric materials in cutting-edge energy storage applications. Here, we propose a high-entropy strategy to design “local polymorphic distorti

Authors: Chen, P.; Li, T.; Yang, Y.; Li, G.; Gao, X.
Journal: Nature Communications (2022)

AbstractSimultaneously harvesting, converting and storing solar energy in a single device represents an ideal technological approach for the next generation of power sources. Herein, we propose a device consisting of an integrated carbon-based perovskite solar cell module capable of harvesting solar energy (and converting it into electricity) and a rechargeable aqueous zinc metal cell. The electrochemical energy storage cell utilizes heterostructural Co2P-CoP-NiCoO2 nanometric arrays and zinc me

Authors: Si, X.; Lu, R.; Zhao, Z.; Yang, X.; Wang, F.
Journal: Nature Communications (2022)

AbstractNatural gas is one of the foremost basic energy sources on earth. Although biological process appears as promising valorization routes to transfer biomass to sustainable methane, the recalcitrance of lignocellulosic biomass is the major limitation for the production of mixing gas to meet the natural gas composition of pipeline transportation. Here we develop a catalytic-drive approach to directly transfer solid biomass to bio-natural gas which can be suitable for the current infrastructu
Black carbon footprint of human presence in Antarctica
Authors: Cordero, R.; Sepúlveda, E.; Feron, S.; Damiani, A.; Fernandoy, F.
Journal: Nature Communications (2022)

AbstractBlack carbon (BC) from fossil fuel and biomass combustion darkens the snow and makes it melt sooner. The BC footprint of research activities and tourism in Antarctica has likely increased as human presence in the continent has surged in recent decades. Here, we report on measurements of the BC concentration in snow samples from 28 sites across a transect of about 2,000 km from the northern tip of Antarctica (62°S) to the southern Ellsworth Mountains (79°S). Our surveys show that BC conte
General heterostructure strategy of photothermal materials for scalable solar-heating hydrogen production without the consumption of artificial energy
Authors: Li, Y.; Bai, X.; Yuan, D.; Zhang, F.; Li, B.
Journal: Nature Communications (2022)

AbstractSolar-heating catalysis has the potential to realize zero artificial energy consumption, which is restricted by the low ambient solar heating temperatures of photothermal materials. Here, we propose the concept of using heterostructures of black photothermal materials (such as Bi2Te3) and infrared insulating materials (Cu) to elevate solar heating temperatures. Consequently, the heterostructure of Bi2Te3and Cu (Bi2Te3/Cu) increases the 1 sun-heating temperature of Bi2Te3from 93 °C to 317

Authors: Wang, J.; Li, F.; Cui, H.; Shi, Q.; Mingee, T.
Journal: Nature Communications (2022)

AbstractThe outbreak of novel coronavirus disease (COVID-19) has resulted in changes in productivity and daily life patterns, and as a result electricity consumption (EC) has also shifted. In this paper, we construct estimates of EC changes at the metropolitan level across the continental U.S., including total EC and residential EC during the initial two months of the pandemic. The total and residential data on the state level were broken down into the county level, and then metropolitan level E

Journal: Nature Communications (2022)

AbstractA lab-on-a-chip system with Point-of-Care testing capability offers rapid and accurate diagnostic potential and is useful in resource-limited settings where biomedical equipment and skilled professionals are not readily available. However, a Point-of-Care testing system that simultaneously possesses all required features of multifunctional dispensing, on-demand release, robust operations, and capability for long-term reagent storage is still a major challenge. Here, we describe a film-le
Electro-active metaobjective from metalenses-on-demand
Authors: Karst, J.; Lee, Y.; Floess, M.; Ubl, M.; Ludwigs, S.
Journal: Nature Communications (2022)

AbstractSwitchable metasurfaces can actively control the functionality of integrated metadevices with high efficiency and on ultra-small length scales. Such metadevices include active lenses, dynamic diffractive optical elements, or switchable holograms. Especially, for applications in emerging technologies such as AR (augmented reality) and VR (virtual reality) devices, sophisticated metaoptics with unique functionalities are crucially important. In particular, metaoptics which can be switched

Authors: Liu, W.; Chou, V.; Behera, R.; Le Ferrand, H.
Journal: Nature Communications (2022)

AbstractMicrostructured composites with hierarchically arranged fillers fabricated by three-dimensional (3D) printing show enhanced properties along the fillers’ alignment direction. However, it is still challenging to achieve good control of the filler arrangement and high filler concentration simultaneously, which limits the printed material’s properties. In this study, we develop a magnetically assisted drop-on-demand 3D printing technique (MDOD) to print aligned microplatelet reinforced comp
Smart low interfacial toughness coatings for on-demand de-icing without melting
Authors: Azimi Dijvejin, Z.; Jain, M.; Kozak, R.; Zarifi, M.; Golovin, K.
Journal: Nature Communications (2022)

AbstractIce accretion causes problems in vital industries and has been addressed over the past decades with either passive or active de-icing systems. This work presents a smart, hybrid (passive and active) de-icing system through the combination of a low interfacial toughness coating, printed circuit board heaters, and an ice-detecting microwave sensor. The coating’s interfacial toughness with ice is found to be temperature dependent and can be modulated using the embedded heaters. Accordingly,
Rising ecosystem water demand exacerbates the lengthening of tropical dry seasons
Authors: Xu, H.; Lian, X.; Slette, I.; Yang, H.; Zhang, Y.
Journal: Nature Communications (2022)

Abstract
                  Precipitation-based assessments show a lengthening of tropical dry seasons under climate change, without considering simultaneous changes in ecosystem water demand. Here, we compare changes in tropical dry season length and timing when dry season is defined as the period when precipitation is less than: its climatological average, potential evapotranspiration, or actual evapotranspiration. While all definitions show more widespread tropical drying than wetting for 1983
Adenosine triphosphate-activated prodrug system for on-demand bacterial inactivation and wound disinfection
Authors: Weng, Y.; Chen, H.; Chen, X.; Yang, H.; Chen, C.
Journal: Nature Communications (2022)

AbstractThe prodrug approach has emerged as a promising solution to combat bacterial resistance and enhance treatment efficacy against bacterial infections. Here, we report an adenosine triphosphate (ATP)-activated prodrug system for on-demand treatment of bacterial infection. The prodrug system benefits from the synergistic action of zeolitic imidazolate framework-8 and polyacrylamide hydrogel microsphere, which simultaneously transports indole-3-acetic acid and horseradish peroxidase in a sing
Widespread shift from ecosystem energy to water limitation with climate change
Authors: Denissen, J.; Teuling, A.; Pitman, A.; Koirala, S.; Migliavacca, M.
Journal: Nature Climate Change (2022)

AbstractTerrestrial ecosystems are essential for food and water security and CO2 uptake. Ecosystem function is dependent on the availability of soil moisture, yet it is unclear how climate change will alter soil moisture limitation on vegetation. Here we use an ecosystem index that distinguishes energy and water limitations in Earth system model simulations to show a widespread regime shift from energy to water limitation between 1980 and 2100. This shift is found in both space and time. While t
Feasibility of hybrid in-stream generator–photovoltaic systems for Amazonian off-grid communities
Authors: Brown, E.; Johansen, I.; Bortoleto, A.; Pokhrel, Y.; Chaudhari, S.
Journal: npj Clean Energy (2022)

Abstract
               While there have been efforts to supply off-grid energy in the Amazon, these attempts have focused on low upfront costs and deployment rates. These “get-energy-quick” methods have almost solely adopted diesel generators, ignoring the environmental and social risks associated with the known noise and pollution of combustion engines. Alternatively, it is recommended, herein, to supply off-grid needs with renewable, distributed microgrids comprised of photovoltaics (PV) and
Isotopic evidence for pallasite formation by impact mixing of olivine and metal during the first 10 million years of the Solar System
Authors: Windmill, R.; Franchi, I.; Hellmann, J.; Schneider, J.; Spitzer, F.
Journal: npj Clean Energy (2022)

Abstract
               Pallasites are mixtures of core and mantle material that may have originated from the core–mantle boundary of a differentiated body. However, recent studies have introduced the possibility that they record an impact mix, in which case an isotopic difference between metal and silicates in pallasites may be expected. We report a statistically significant oxygen isotope disequilibrium between olivine and chromite in main group pallasites that implies the silicate and metal p

Authors: Garritano, A.; Song, W.; Thomas, T.
Journal: npj Clean Energy (2022)

AbstractCarbon fixation is a critical process for our planet; however, its distribution across the bacterial and archaeal domains of life has not been comprehensively studied. Here, we performed an analysis of 52,515 metagenome-assembled genomes and discover carbon fixation pathways in 1,007 bacteria and archaea. We reveal the genomic potential for carbon fixation through the reverse tricarboxylic acid cycle in previously unrecognized archaeal and bacterial phyla (i.e. Thermoplasmatota and Elusi

Authors: Eguchi, J.; Diamond, C.; Lyons, T.
Journal: npj Clean Energy (2022)

Abstract
               Oxygen and carbon are 2 elements critical for life on Earth. Earth's most dramatic oxygenation events and carbon isotope excursions (CIE) occurred during the Proterozoic, including the Paleoproterozoic Great Oxidation Event and the associated Lomagundi CIE, the Neoproterozoic Oxygenation event, and the Shuram negative CIE during the late Neoproterozoic. A specific pattern of a long-lived positive CIE followed by a negative CIE is observed in association with oxygenation e
Unexpected no significant soil carbon losses in the Tibetan grasslands due to rodent bioturbation
Authors: Huang, M.; Gan, D.; Li, Z.; Wang, J.; Niu, S.
Journal: npj Clean Energy (2022)

AbstractThe Tibetan grasslands store 2.5% of the Earth’s soil organic carbon. Unsound management practices and climate change have resulted in widespread grassland degradation, providing open habitats for rodent activities. Rodent bioturbation loosens topsoil, reduces productivity, changes soil nutrient conditions, and consequently influences the soil organic carbon stocks of the Tibetan grasslands. However, these effects have not been quantified. Here, using meta-analysis and upscaling approach
Structural measures of personal networks predict migrants’ cultural backgrounds: an explanation from Grid/Group theory
Authors: Molina, J.; Ozaita, J.; Tamarit, I.; Sánchez, A.; McCarty, C.
Journal: npj Clean Energy (2022)

Abstract
               Culture and social structure are not separated analytical domains but intertwined phenomena observable in personal networks. Drawing on a personal networks dataset of migrants in the United States and Spain, we show that the country of origin, a proxy for diverse languages and cultural institutions, and religion may be predicted by specific combinations of personal network structural measures (closeness, clustering, betweenness, average degree, etc). We obtain similar res
Cryocampsis: a biophysical freeze-bending response of shrubs and trees under snow loads
Authors: Ray, P.; Bret-Harte, M.
Journal: npj Clean Energy (2022)

Abstract
               We report a biophysical mechanism, termed cryocampsis (Greek cryo-, cold, + campsis, bending), that helps northern shrubs bend downward under a snow load. Subfreezing temperatures substantially increase the downward bending of cantilever-loaded branches of these shrubs, while allowing them to recover their summer elevation after thawing and becoming unloaded. This is counterintuitive, because biological materials (including branches that show cryocampsis) generally become

Authors: Buonocore, J.; Salimifard, P.; Magavi, Z.; Allen, J.
Journal: Scientific Reports (2022)

AbstractBuilding electrification is essential to many full-economy decarbonization pathways. However, current decarbonization modeling in the United States (U.S.) does not incorporate seasonal fluctuations in building energy demand, seasonal fluctuations in electricity demand of electrified buildings, or the ramifications of this extra demand for electricity generation. Here, we examine historical energy data in the U.S. to evaluate current seasonal fluctuation in total energy demand and managem

Heterogeneous climate change impacts on electricity demand in world cities circa mid-century
Authors: Romitti, Y.; Sue Wing, I.
Journal: Scientific Reports (2022)

Abstract
                  
                    Rising ambient temperatures due to climate change will increase urban populations’ exposures to extreme heat. During hot hours, a key protective adaptation is increased air conditioning and associated consumption of electricity for cooling. But during cold hours, milder temperatures have the offsetting effect of reducing consumption of electricity and other fuels for heating. We elucidate the net consequences of these opposing effects in 36 cities
Demonstration of static electricity induced luminescence
Authors: Kikunaga, K.; Terasaki, N.
Journal: Scientific Reports (2022)

AbstractCan we visualise static electricity, which everyone in the world knows about? Since static electricity is generated by contact or peeling, it may be a source of malfunction of electronic components, whose importance is steadily increasing, and even cause explosion and fire. As static electricity is invisible, makeshift measures of static electricity are taken on various surfaces; there is also a common view that it is hard to take effective measures. Here we present a specific luminescen

Authors: Kamranzad, B.; Amarouche, K.; Akpinar, A.
Journal: Scientific Reports (2022)

AbstractThe sustainability of wave energy linked to the intra- and inter-annual variability in wave climate is crucial in wave resource assessment. In this study, we quantify the dependency of stability of wave energy flux (power) on long-term variability of wind and wave climate to detect a relationship between them. We used six decades of re-analysis wind and simulated wave climate in the entire globe and using two 30-yearly periods, we showed that not only the previously suggested minimum per

Authors: Rad, N.; Bekker, A.; Arashi, M.
Journal: Scientific Reports (2022)

AbstractWind energy production depends not only on wind speed but also on wind direction. Thus, predicting and estimating the wind direction for sites accurately will enhance measuring the wind energy potential. The uncertain nature of wind direction can be presented through probability distributions and Bayesian analysis can improve the modeling of the wind direction using the contribution of the prior knowledge to update the empirical shreds of evidence. This must align with the nature of the
