Survival of reactive carbon through meteorite impact melting

Melt fragments in melt breccias from the Gardnos impact crater, Norway, contain abundant carbon. A high proportion of the carbon present in the original melt was preserved. The stripping of hydrogen from carbon during melting prevents later hydrocarbon formation, hence the carbon is fixed in place rather than volatilized. Underlying lithic breccias that were not melted record hydrocarbon generatio

Feasibility trade-offs in decarbonising the power sector with high coal dependence : The case of Korea

Decarbonising the power sector requires feasible strategies for the rapid phase-out of fossil fuels and the expansion of low-carbon sources. This study assesses the feasibility of plausible decarbonisation scenarios for the power sector in the Republic of Korea through 2050 and 2060. Our power plant stock accounting model results show that achieving zero emissions from the power sector by the mid-

CHRISGAS-Intermediate Report

This intermediate report presents some of the important findings of the research work carried out during the first three years of the CHRISGAS project. The report is aimed at a broad technical-oriented audience such as: engineers with a general interest in the state-of-the-art and new developments in the biomass-to automotive fuel sector, and/or to teachers/lecturers/students in technical subjects

Small Scale Reformers for on-site Hydrogen Supply

This paper presents the major outcome of the IEA Hydrogen Implementing Agreement (IEA-HIA) Task 23 “Small-scale reforming for on-site hydrogen supply”. The task is briefly described, including the three sub-tasks: harmonized industrialization, sustainability and renewables and market information. An exclusive network of worldwide suppliers of reformers as well as gas companies has contributed to

Altitudinal variation in impacts of snow cover, reservoirs and precipitation seasonality on monthly runoff in Tibetan Plateau catchments

Understanding monthly runoff variability, its spatio-temporal characteristics, and key drivers under climate change and human impacts is crucial for long-term water resource management. However, current knowledge remains limited, especially in high-elevation, seasonally cold regions. Focusing on 10 sub-basins along an elevation gradient (1000 to 5900 ma.s.l.) in the hydrologically complex Yalong R

Energy security under de-carbonization scenarios: An assessment framework and evaluation under different technology and policy choices

How would a low-carbon energy transformation affect energy security? This paper proposes a frame- work to evaluate energy security under long-term energy scenarios generated by integrated assessment models. Energy security is defined as low vulnerability of vital energy systems, delineated along geographic and sectoral boundaries. The proposed framework considers vulnerability as a combination of

Large Eddy Simulation of Turbulent Flows in Combustor Related Geometries

Numerical simulations using Large Eddy Simulation (LES) are applied to turbulent swirling flow fields. The swirling motion is often introduced into combustors to act as flame holders or enhance the mixing between species. Different turbulence models capture the swirling motion more or less accurately. LES is well suited for understanding details of swirling flows. It resolves all the large scales

A Concept of a Para-Hydrogen-Based Cold Neutron Source for Simultaneous High Flux and High Brightness

A novel concept of cold neutron source employing chessboard or staircase assemblies of high-aspect-ratio rectangular para-hydrogen moderators with well-developed and practically fully illuminated surfaces of the individual moderators is proposed. An analytic approach for calculating the brightness of para-hydrogen moderators is introduced. Because the brightness gain originates from a near-surface

Aseptic Packaging for Energy Efficiency and Resilient Food Supply: A Comparative Study of Milk Preservation

Global food systems are increasingly vulnerable to climate change, energy volatility, and geopolitical disruptions—threatening the security and stability of perishable supply chains. This thesis investigates the potential of aseptic packaging technologies, specifically ultra-high-temperature (UHT) treatment and sterile filling, as a means to reduce energy consumption and enhance resilience in the

Adipose Clocks: Burning the Midnight Oil.

Circadian clocks optimize the timing of physiological processes in synchrony with daily recurring and therefore predictable changes in the environment. Until the late 1990s, circadian clocks were thought to exist only in the central nervous systems of animals; elegant studies in cultured fibroblasts and using genetically encoded reporters in Drosophila melanogaster and in mice showed that clocks a

Regulation of carbohydrate metabolism by nitric oxide and hydrogen sulfide : Implications in diabetes

Nitric oxide (NO) and hydrogen sulfide (H2S) are two gasotransmitters that are produced in the human body and have a key role in many of the physiological activities of the various organ systems. Decreased NO bioavailability and deficiency of H2S are involved in the pathophysiology of type 2 diabetes and its complications. Restoration of NO levels have favorable metabolic effects in diabetes. The

Transition to a β-sheet-rich structure in spidroin in vitro : The effects of pH and cations

Unlike man-made fibers, the silks of spiders are spun from aqueous solutions and at atmospheric pressure in a process still poorly understood. The molecular mechanism of this process involves the conversion of a highly concentrated, predominantly disordered silk protein (spidroin) into β-sheet-rich structures. To help store and transport the spidroins in solution, as well as probably control their
