Broad-band High-Energy Resolution Hard X-ray Spectroscopy using Transition Edge Sensors at SPring-8
Shinya Yamada, Yuto Ichinohe, Hideyuki Tatsuno +40
We have succeeded in operating a transition-edge sensor (TES) spectrometer and evaluating its performance at the SPring-8 synchrotron X-ray light source. The TES spectrometer consi…
Atmospheric Methane Removal as a Third Climate Intervention: Termination Risks and Air Pollutant Effects
Katsumasa Tanaka, Weiwei Xiong, Didier A. Hauglustaine +8
Atmospheric Methane Removal (AMR) is a third class of climate intervention, along with Carbon Dioxide Removal (CDR) and Solar Radiation Management (SRM). We show that, unlike CDR,…
Chern junctions in Moiré-Patterned Graphene/PbI2
Sun Yan, M. Monteverde, V. Derkach +5
Expanding the moire material library continues to unlock novel quantum phases and emergent electronic behaviors. Here, we introduce PbI2 into the moire family and investigate the m…
Bulk Nanostructured Zirconia Ceramics with High Hardness and Toughness via Integration of High-Pressure Torsion and Spark Plasma Sintering
Kaveh Edalati, Koji Morita, Shivam Dangwal +1
Developing nanostructured bulk ceramics is a major challenge when conventional high-temperature sintering is employed for consolidation. In the current investigation, yttria-stabil…
Behaviors of Martian CO2-driven dry climate system and conditions for atmospheric collapses
Yasuto Watanabe, Eiichi Tajika, Arihiro Kamada
The present Martian climate is characterized by a cold and dry environment with a thin atmosphere of carbon dioxides (CO2). In such conditions, the planetary climate and habitabili…
Aligning long-term climate mitigation with enhanced methane action
Katsumasa Tanaka, Kushal Tibrewal, Philippe Ciais +1
The Global Methane Pledge and other methane measures may potentially undermine CO2 mitigation in certain countries, unless they are considered as additional to the existing Nationa…
Direct Observation and Quantitative Measurement of OH Radical Desorption During the Ultraviolet Photolysis of Liquid Nonanoic Acid
Naoki Numadate, Shota Saito, Yuki Nojima +3
Ultraviolet (UV) photolysis of fatty acid surfactants which cover the surfaces of atmospheric liquid aerosols and are found in the oceans such as nonanoic acid (NA) has recently be…
Rotational effect as the possible cause of the east-west asymmetric crater rims on Ryugu observed by LIDAR data
Naoyuki Hirata, Noriyuki Namiki, Fumi Yoshida +13
Asteroid 162173 Ryugu is a rubble-pile asteroid, whose top-shape is compatible with models of deformation by spin up. Rims of major craters on Ryugu have an east-west asymmetric pr…
Assessment of waterfront office redevelopment plan on optimal building energy demand and rooftop photovoltaics for urban decarbonization
Younghun Choi, Takuro Kobashi, Yoshiki Yamagata +1
Designing waterfront redevelopment generally focuses on attractiveness, leisure, and beauty, resulting in various types of building and block shapes with limited considerations on…
Deeply decarbonizing residential and urban central districts through photovoltaics plus electric vehicle applications
Takuro Kobashi, Younghun Choi, Yujiro Hirano +2
With the costs of renewable energy technologies declining, new forms of urban energy systems are emerging that can be established in a cost-effective way. The SolarEV City concept…
Paris Agreement requires substantial, broad, and sustained engagements beyond COVID-19 public stimulus packages
Katsumasa Tanaka, Christian Azar, Olivier Boucher +3
It has been claimed that COVID-19 public stimulus packages could be sufficient to meet the short-term energy investment needs to leverage a shift toward a pathway consistent with t…
Global Daily CO emissions for the year 2020
Zhu Liu, Zhu Deng, Philippe Ciais +25
The diurnal cycle CO emissions from fossil fuel combustion and cement production reflect seasonality, weather conditions, working days, and more recently the impact of the COVI…
Local field effects in ultrafast light-matter interaction measured by pump-probe spectroscopy of monolayer MoSe
Aleksander Rodek, Thilo Hahn, Jacek Kasprzak +10
Using a novel approach to ultrafast resonant pump-probe spectroscopy we investigate the spectral shape and dynamics of absorption features related to the A exciton in an hBN/MoSe$_…
Carbon Monitor: a near-real-time daily dataset of global CO2 emission from fossil fuel and cement production
Zhu Liu, Philippe Ciais, Zhu Deng +15
We constructed a near-real-time daily CO2 emission dataset, namely the Carbon Monitor, to monitor the variations of CO2 emissions from fossil fuel combustion and cement production…
Cost-effective implementation of the Paris Agreement using flexible greenhouse gas metrics
Katsumasa Tanaka, Olivier Boucher, Philippe Ciais +2
Greenhouse gas (GHG) metrics, that is, conversion factors to evaluate the emissions of non-CO2 climate forcers on a common scale with CO2, serve crucial functions upon the implemen…
COVID-19 causes record decline in global CO2 emissions
Zhu Liu, Philippe Ciais, Zhu Deng +37
The considerable cessation of human activities during the COVID-19 pandemic has affected global energy use and CO2 emissions. Here we show the unprecedented decrease in global foss…
Scalable GWR: A linear-time algorithm for large-scale geographically weighted regression with polynomial kernels
Daisuke Murakami, Narumasa Tsutsumida, Takahiro Yoshida +2
Although a number of studies have developed fast geographically weighted regression (GWR) algorithms for large samples, none of them has achieved linear-time estimation, which is c…
Which country epitomizes the world? A study from the perspective of demographic composition
Takahiro Yoshida, Rim Er-Rbib, Morito Tsutsumi
Demographic indicators are an essential element in considering various problems in the social economy, such as predicting economic fluctuations and establishing policies. The liter…
Interference induced enhancement of magneto-optical Kerr effect in ultrathin magnetic films
