Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

Deep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

ForestERW: a spatially explicit carbon dioxide removal model for practical enhanced rock weathering applications in United States forests

Frontiers in Climate
Enhanced rock weathering (ERW) is an emerging carbon dioxide removal (CDR) pathway that has been heavily explored for agricultural systems. There may also be co-benefits from this approach in historically acidified forest ecosystems by replenishing ...

Geoengineering impact of open ocean dissolution of olivine on atmospheric CO2, surface ocean pH and marine biology

Environmental Research Letters, 2013
Ongoing global warming induced by anthropogenic emissions has opened the debate as to whether geoengineering is a ‘quick fix’ option. Here we analyse the intended and unintended effects of one specific geoengineering approach, which is enhanced ...

REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence [PDF]

, 2001
Very few studies deal with REE (rare earth element) mobility within the system soil–soil solution–streamwater. In this article, we try to characterize the fractionation and the migration of the REE in a granite-derived soil system located in a small ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Adapting and Verifying the Liming Index for Enhanced Rock Weathering Minerals as an Alternative Liming Approach

Land
Acidic soils limit plant nutrient availability, leading to deficiencies and reduced crop yields. Agricultural liming agents address these issues and are crucial for deploying silicate amendments used in enhanced rock weathering (ERW) for carbon sequestration and emission reduction. Grower recommendations for liming agents are based on the liming index (

Calcite is an efficient and low-cost material to enhance benthic weathering in shelf sediments of the Baltic Sea

Communications Earth & Environment
Recent studies have proposed calcite and dunite as possible alkaline materials for enhanced benthic weathering in shallow depocenters of the Baltic Sea as a marine carbon dioxide removal strategy.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Interactions between silicate weathering and ectomycorrhiza in severely acidified forests

Communications Earth & Environment
Soil acidification driven by anthropogenic nitrogen (N) deposition is a growing global threat to forest health. Aside from direct nutrient-related effects, as forest soils acidify, severe reductions in ectomycorrhizal (EcM) fungi abundance and diversity ...
