Contamination of surface waters by mining wastes in the Milluni Valley (Cordillera Real, Bolivia): Mineralogical and hydrological influences [PDF]

, 2008
This study is one of very few dealing with mining waste contamination in high altitude, tropical-latitude areas exploited during the last century. Geochemical, mineralogical and hydrological characterizations of potentially harmful elements (PHEs) in ...

Electropolymerized Aptasensor for Femtogram‐Level Cytokine Detection

Advanced Materials, EarlyView.
Electropolymerization of 3‐amino‐ʟ‐tyrosine creates ultrathin, smooth, and chemically robust pALT nanofilms with accessible carboxyl functionalities for direct aptamer immobilization. Integrated with fiber‐optic SPR and OECT platforms, these interfaces enable IL‐6 detection down to 100 fg mL−1 and provide a versatile route to bioelectronic sensing ...

Examining Point-Nonpoint Trading Ratios for Acid Mine Drainage Remediation with a Spatial-Temporal Optimization Model [PDF]

A trading ratio is required for water quality trading that involves nonpoint sources to compensate for the difficulty of determining nonpoint loadings, the stochastic characteristics of nonpoint loadings, and the uncertainty inherent in nonpoint source ...

Acid mine drainage in British Columbia : today and tomorrow

, 1987
Of the 16 metal mines currently operating in British Columbia, five generate acid mine drainage. At least five abandoned mines also produce acid mine drainage.

Recovery of Metals from Acid Mine Drainage

Chemical Engineering Transactions, 2012
Acid Mine Drainage (AMD) poses a severe pollution problem attributed to current and past mining activities. Low pH, high concentrations of sulphates and various heavy metals makes AMD treatment a major concern because of possible deleterious effects of ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Characterization of Dar Bouaazza’s Mine Tailings Using Xrf, Acid-Base Accounting, And Leaching Tests (Taza Province, Morocco) [PDF]

BIO Web of Conferences
The present work evaluates the potential of Dar Bouaazza's mine tailings, located in Taza province Morocco, to generate acid mine drainage. In this regard, four samples (R2, R3, R6 and R7) were collected from the wastes left from previous mining ...

Unveiling the Hidden Geometry of OECTs: Contact‐Semiconductor Overlap Driven Errors in Volumetric Capacitance

Advanced Materials Technologies, EarlyView.
This work examines how contact–semiconductor overlap influences volumetric capacitance extraction in organic electrochemical transistors as device dimensions shrink. It shows that neglecting overlap leads to systematic, geometry‐driven errors in capacitance values.

Advances in acid rock drainage (ARD) characterisation of mine wastes

, 2006
Research was carried out to improve acid rock drainage (ARD) prediction methodologies, focussing on resolving uncertainties in acid base accounting (ABA) methods. Advancements, their application, and interpretation are reported. Consideration of both net
