Preparation of superfine and semi-hydrated flue gas desulfurization gypsum powder by a superheated steam powdered jet mill and its application to produce cement pastes

open access: yesCase Studies in Construction Materials, 2022
The low reactivity, high moisture content, and gap-graded particle size distribution of flue gas desulfurization (FGD) gypsum clearly restrict its large-scale application, particularly for cement production.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

open access: yesAdvanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Customized three dimensionally printed palatal stents: A randomized controlled clinical trial

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Soft tissue grafts are commonly used in periodontal surgery around teeth and implants. However, few studies have examined donor‐site pain through patient‐reported outcomes following soft tissue grafting. This study aimed to minimize donor‐site pain during autologous gingival grafting using a three‐dimensionally (3D)‐printed stent ...
