Carbon/TiO2 Materials From Textile Waste: A Sustainable Approach for Dye Removal
Environmental Quality Management, Volume 35, Issue 3, Spring 2026.ABSTRACT This study synthesized carbon/TiO2 composites from textile waste through titanium isopropoxide impregnation and calcination to address dye contamination in wastewater. The composites exhibited enhanced specific surface area and pore volume with higher TiO2 content.

Thickness Calculation of Pigment Layers and Gold Leaves Using XRF and MA‐XRF Data
X-Ray Spectrometry, Volume 55, Issue 2, Page 335-348, March/April 2026.ABSTRACT In this work, XRF and MA‐XRF data were used to estimate the thickness of Chromium Oxide (Cr₂O₃) pigment and gold leaf applied over Lead White (2PbCO3.Pb(OH)2). The thickness determination was based on the differential attenuation of the Pb‐Lα and Pb‐Lβ characteristic X‐rays, which allows correlating the overlying material layer with the Pb(Lα ...

Beyond Core‐Periphery: A Multidimensional Typology of Brazilian Regional Inventive Capacity
Growth and Change, Volume 57, Issue 1, March 2026.ABSTRACT The geography of invention in Brazil is characterized by a profound and multi‐polarised structure that extends beyond a simple core‐periphery dichotomy. This paper demonstrates this complexity through a multidimensional analysis of inventive capacity (2000–2023), operationalised along four axes—‘how much’, ‘who’, ‘how’, and ‘what’ is invented ...

Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.Photosynthetische Mikroorganismen können zur lichtgetriebenen H2‐Entwicklung genutzt werden. Eine Einschränkung ist jedoch die damit verbundene Bildung von molekularem Sauerstoff als Nebenprodukt der Photosynthese, der die Aktivität des Biokatalysators für die H2‐Produktion, d. h. die Hydrogenase, inhibiert.

Angewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.Photosynthetic microorganisms can be used to perform H2 evolution driven by light. However, a crucial limitationlies in the associated generation of molecular oxygen as a by‐product of photosynthesis, which compromises the activity of the biocatalyst performing H2 production, i.e., the hydrogenase.
