Physical research of the water flow on spillways of hydraulic structures

, 2014
Cílem této práce bylo získání charakteristiky poměrně nových tří typů přelivů a následné porovnání těchto charakteristik s charakteristikou známých a využívaných přelivů. Nejdříve bylo vybráno 8 typů přelivů, těmi byly: přeliv se širokou korunou, přeliv

Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.

Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Nested Institutions and Overlapping Mandates: A Policy Analysis of Mangrove Governance in Ghana, Tanzania Mainland, and Zanzibar

Environmental Policy and Governance, EarlyView.
ABSTRACT Mangroves are critical resources in sustaining coastal communities by providing essential ecosystem goods and services. Occurring within the interface of land and sea, they serve as critical ecological zones shaped by dynamic interactions between terrestrial and marine systems.

Learning Networks Drive Environmental Innovation: Evidence From Fourth‐Stage Purification Diffusion

Environmental Policy and Governance, EarlyView.
ABSTRACT Contaminants of emerging concern, including pharmaceuticals and industrial chemicals, threaten water quality globally. In the European Union (EU), until the adoption of the revised Urban Wastewater Treatment Directive in 2024, a regulatory gap had left the member states and the municipalities in them without binding removal standards ...
