Spatial distribution of acid mine drainage indexes in diferente water environments [PDF]

open access: yes, 2019
The Iberian Pyrite Belt is one of the largest metallogenic province in the world. The characteristics of this region have a reflection on the existence of Acidic Mine Drainage (AMD) discharged into the river network affecting the water quality. A several

Hydraulic response and oxygen barrier performance of earthen cover constructed with solid wastes: from soil column test to field demonstration

open access: yesYantu gongcheng xuebao
Reducing the source of acid mine drainage is very important for the ecological restoration of acid mines and tailings dumps, the research and development of earthen cover constructed with solid wastes is of great scientific and engineering value for ...

An Avalanche Effect Nanomodulator Triggers Cascade Ferroptosis/Cuproptosis for Immunosuppressive Microenvironment Remodeling

open access: yesAdvanced Science, EarlyView.
A nanomodulator called L‐Arginine/lificiguat@Copper‐hollow Prussian blue@Calcium phosphate nanoparticles is constructed to launch a self‐amplifying “avalanche effect” in tumor cells. The ensuing cascade, triggered by the acidic tumor microenvironment and near‐infrared light, induces calcium overload, generates a reactive oxygen species and reactive ...

Acid Mine Drainage and Minesite Stability (Technical Paper 9509)

open access: yes, 1995
Acid mine drainage (AMD) and minesite salinity are arguably the most serious threats posed to the environment by open cut mining and mineral processing. AMD arises when sulphur, usually in the form iron sulphide (pyrite) contained in the ore and/or waste

An Intravesical Akkermansia muciniphila‐Based Chemo‐Immunotherapeutic Platform for Bladder Cancer

open access: yesAdvanced Science, EarlyView.
Pasteurized Akkermansia muciniphila is engineered into an intravesical F127/doxorubicin platform that couples localized chemotherapy with immune remodeling. By inducing apoptosis, ferroptosis, and immunogenic cell death, this chemo‐immunotherapeutic system enhances dendritic‐cell maturation, antigen cross‐presentation, and tumor‐specific CD8+ T‐cell ...

TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis

open access: yesAdvanced Science, EarlyView.
A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...

Overcoming Drug Resistance by Paclitaxel Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
In the murine triple‐negative breast cancer (TNBC) model, chemotherapy effectively increases tumor neoantigen burden (TNB). Here, the study constructs a liposomal nanovaccine using antigens derived from in vitro chemotherapy‐treated paclitaxel‐resistant TNBC 4T1 cells.

Acid Mine Drainage And The Acid Drainage Index

open access: yes, 1981
Acid drainage is a naturally occurring process that often results from weathering and oxidation of impurities in coal. When coal is exposed through mining, the problem is magnified and it is estimated that some 11,000 miles of streams in the United ...
