Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

open access: yesFire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Stock Price Deviations From Fundamentals Levels: Mis‐Valuation due to Investor Overconfidence?

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We use the Residual Income Valuation Model to obtain fundamental values for sample stocks in six Eurozone markets. We then estimate the deviation between the fundamental values and actual stock prices. Subsequently, we examine whether these deviations can be systematically explained by business cycle trends, trends in local economic sentiment,

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

open access: yesPolymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

Social Sustainability in Circular Bioeconomy Business Models: Insights From Argentina

open access: yesSustainable Development, EarlyView.
ABSTRACT Research on circular bioeconomy business models (CBEBM) has largely prioritised environmental and economic aspects, leaving out the social pillar. To address this gap, this paper analyses to what extent and in what ways social sustainability is integrated into CBEBM, based on 12 cases from northern Argentina, a region with high potential for ...
