Rational Use of Land Resource During the Implementation of Transportless System of Coal Strata Surface Mining [PDF]

, 2017
Surface mining and open pits engineering affect the environment in a very negative way. Among other pollutions that open pits make during mineral deposits exploiting, particular problem is the landscape changing. Along with converting the land into pits,

A Sustainable Biotechnology Approach for Mineral Separation

Advanced Functional Materials, EarlyView.
Silver‑binding peptides are first identified through phage‐display screening, and then engineered into multifunctional and responsive peptides or proteins. These tailored biomolecules can selectively capture and aggregate silver particles or ions from complex mixtures, enabling rapid and efficient silver separation and recovery.

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Fine‐Tunning BaCo0.4Fe0.4Zr0.1Y0.1O3−δ‐Based Air Electrodes for Reversible Protonic Ceramic Cells via Co‐Engineering A‐site Deficiency and Nickel Content

Advanced Functional Materials, EarlyView.
A synergistic strategy combining A‐site deficiency and B‐site nickel doping yielded a BCFZYN‐095‐01 nanocomposite air electrode for reversible protonic ceramic cells with superior ORR/OER activities. B‐site deficiency in the perovskite lattice enhances proton conduction, and nickel doping within the bulk facilitates oxygen transport.
