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

Advanced NanoBiomed Research, Volume 6, Issue 8, August 2026.
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.

Targeting Human Protein Kinase CK2 by a Library of Indeno[1,2‐b]Indoles: Contribution of Thermal Shift Assay to Pre‐Screening and Co‐Crystallization to Post‐Screening

Archiv der Pharmazie, Volume 359, Issue 8, August 2026.
A series of 25 functionalized indeno[1,2‐b]indoles was selected from in‐house compound library and additional synthesis work. Capillary electrophoresis‐based and thermal shift assays, X‐ray analysis of small molecules, and co‐crystallization studies highlighted a key molecular template for the inhibitory potential of protein kinase CK2.

Competing Pathways in Heme Catalyzed Oxidations With Porphyrin‐Centered Reactivity

ChemistryEurope, Volume 4, Issue 8, August 2026.
Heme‐catalyzed oxidations proceeding through porphyrin‐centered reactivity are quite rare. In attempts to optimize the catalytic umpolung of chloride proceeding via an isoporphyrin, we found a competing pathway. The iron(III) π‐dication readily performs alternative reactivity, leading to a bifurcation in reaction mechanisms at this point.

Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 3996-4006, August 2026.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Mechanistic Insights and Performance Advancements in Flow Capacitive Deionisation for Sustainable Energy Conversion

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Flow capacitive deionisation is an advanced electrochemical technology for water purification and energy‐related applications. It represents a viable alternative to conventional desalination methods due to its low operating voltage, continuous electrode regeneration, and stable performance under moderate‐to‐high salinity conditions. The use of

KINETICS AND MECHANISM OF AERIAL OXIDATION OF HYDROQUINONE IN A DEVELOPER SOLUTION AND DETERMINATION OF DEVELOPER'S HALF-LIFE AT 20°C [PDF]

Journal of Sciences, Islamic Republic of Iran, 1995
The aerial oxidation of hydroquinone in a freshly prepared developer solution at 20°C has been studied through the measurement of concentration changes by a spectrophotometric method. The concentration of consumed hydroquinone is directly proportional to

Interaction Among Microbiota, Chemical Composition, and Quality Variations in Coffea arabica Across Altitudinal Gradients During Wet Processing

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Fermentation significantly altered the dominant bacterial genera from Sphingomonas and Pleomorphomonas (before fermentation) to Weissella and Lactobacillus (after fermentation), while Cladosporium and Fusarium remained the dominant fungal genera. Notably, non‐volatile compounds in de‐pulping coffee beans and volatile compounds of roasted coffee beans ...
