Theodor Steinbüchel's Great Figures of Christian Humanism

Modern Theology, EarlyView.
Abstract Theodor Steinbüchel (1888–1949) offers a study of eight figures in Western history who may be regarded as gestalts of Christian Humanism. He argued that none of these eight figures will ever return in the same way, but since there was an eternal conception of Christianity to which their ethos gave human form, each of these gestalts can be ...

UV Absorption Spectral Characteristics of Dissolved Organic Matter in Fen River of Taiyuan in China

E3S Web of Conferences, 2018
UV absorption is one of the important properties of chromophoric dissolved organic matter (CDOM). The UV absorption spectral characteristics of dissolved organic matter (DOM) were analyzed to infer the main components in Taiyuan urban section.

Dissolved Organic Matter (DOM) in the open Mediterranean Sea. I. Basin–wide distribution and drivers of chromophoric DOM [PDF]

Progress in Oceanography, 2018
Original research article Chromophoric dissolved organic matter (CDOM) in the open Mediterranean Sea (MedSea) is barely documented, remaining the basin–wide patterns in intermediate and deep waters still enigmatic. Here, full–depth distributions of CDOM absorption coefficients and spectral slopes recorded during the HOTMIX 2014 cruise are presented and

Measurement and modeling of diffuse ultraviolet radiation: A review

Photochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.

Linking Plant and Microbial Traits to Soil Carbon for Reliable and Resilient Bioenergy Systems

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Plant–microbe–soil interactions supporting productivity and soil carbon storage in bioenergy systems. Plants supply organic inputs that sustain microbial communities driving nutrient cycling, carbon stabilization, and soil aggregation. These interactions enhance soil structure and nutrient retention, supporting both biomass productivity and broader ...

Differences in dissolved organic matter and analysis of influencing factors between plantations pure and mixed forest soils in the loess plateau

Frontiers in Forests and Global Change
The dissolved organic matter (DOM) in forest ecosystems significantly impacts soil carbon cycling due to its active turnover characteristics. However, whether different plantation forest soil profiles exhibit distinct DOM characteristics remains unclear.

Enhanced Solar Radiation Attenuation in the Arctic Shelf Driven by Warming‐Induced Terrestrial Inputs

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Arctic warming accelerates permafrost thaw and coastal erosion, increasing terrestrial material transport to the ocean. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data (2002–2023), we report a widespread increase in the diffuse attenuation coefficient Kd(490) across Arctic shelves since 2018, notably in the Laptev and Kara ...

Universal molecular structures in natural dissolved organic matter

Nature Communications, 2018
Dissolved organic matter (DOM) in aquatic systems is among the most complex molecular mixtures known. Here the authors show that a major component in DOM is molecularly indistinguishable in marine and freshwater environments, which could reflect ...

Elucidating the Reactivity and Fate of Dissolved Organic Matter in Groundwater Entering the Alaska Beaufort Sea Coast Using 14C Ramped Oxidation

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Supra‐permafrost groundwater (SPGW) is a significant but understudied source of dissolved organic matter (DOM) to Arctic coastal systems. We applied ramped pyrolysis/oxidation (RPO) with Δ14C and δ13C isotopic analysis to assess DOM reactivity and origin in SPGW, river, and lagoon waters along the Alaska Beaufort Sea coast.
