Spatial diagnosis and regulation conception of open-pit coal mine ecosystem disturbance in arid and semi-arid areas

open access: yesMeitan xuebao
Open-pit coal mines in arid and semi-arid areas are a crucial component of national coal resources, which occupy an essential position in promoting regional economic growth and meeting rising energy demand. However, numerous challenges are caused by open-

Underground Signals: The Ecological Power of Root Volatiles

open access: yesAdvanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

The persistence of life measured by carbon cycling in closed ecological systems [PDF]

open access: yes, 1986
Materially closed energetically open ecological systems have been observed to support biological activity for over 10 years. It has been suggested that closed ecological systems (CES), as models of the earths biosphere, will support life indefinitely ...

The role of plant disease in the development of controlled ecological life support systems [PDF]

open access: yes, 1986
Plant diseases could be important factors affecting growth of higher plants in Closed Ecological Life Support Systems (CELSS). Disease control, therefore, will be needed to maintain healthy plants.

Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

open access: yesAdvanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Generation of toxic substances in closed ecological systems

open access: yes, 1982
The atmospheres of closed ecological systems, such as spacecraft and submarines, have been found to contain hundreds of individual compounds. Although most of these compounds are present only in trace amounts, some are known to be hazardous to human ...

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...
