Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

A Green Consumer‐Based Approach to Advance Branding Strategies in Experiential Consumption Contexts. Insight From the Cruise Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Growing environmental awareness has intensified demand for sustainability and transparency, especially in cruise tourism, a high‐impact and highly scrutinised service context. This study examines how green consumption values (GCV) shape passengers' perceptions of the credibility of green marketing claims (believability) and, in turn, influence

Experimental Investigation on the Effect of Dry and Wet Activation Processes on the Morphological Properties of Activated Carbon Derived From Sugarcane Bagasse

open access: yesCarbon Innovation, EarlyView.
Synthesis and characterization of sugarcane bagasse‐derived activated carbon via KOH‐assisted dry and wet activation. ABSTRACT This study explores the impact of activation processes on the morphological properties of activated carbon. Carbon is initially produced through vacuum pyrolysis at three temperatures (500°C, 600°C, and 700°C), with a heating ...

Enhanced hydrosuction performance for cohesive sediment removal in low-head reservoirs

open access: yesAin Shams Engineering Journal, 2017
Deposited sediment removal or dredging is generally required in many hydro-system projects. Siphon dredging or hydrosuction bears many advantages including low energy consumption, minor turbidity generation and ability of localized dredging. A new device

Thermal Degradation of PFAS in Different Scales: Measurement of Hydrogen Fluoride (HF)

open access: yesChemie Ingenieur Technik, EarlyView.
The communication article is about the challenges to balance a combustor in the case of fluorine when incinerating PFAS containing materials. Several analytical methods are compared: for continuous measurement, FTIR with TDLS. The detected fluorine species are further compared with results upon IC and pyrohydrolysis for discontinuous measurements in ...

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...
