Sustainable Utilization and Fire Protection of Wood‐Based Composites in Buildings: Innovations, Challenges, and Future Directions

open access: yesSustainable Development, EarlyView.
ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

open access: yesSafety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Polyphosphate metabolism in Acinetobacter johnsonii 210A [PDF]

open access: yes, 1993
Since the seventies, there is a growing interest in the process of biological phosphate removal in which microorganisms able to accumulate large amounts of phosphate play a central role. Over the years many bacteria have been isolated from sludge systems

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

The Crystal Structures of High‐ and Low‐Temperature Silver Pyrophosphate: Structural Instability and Its Consequences

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

A comprehensive review of cancer‐induced cardiac wasting

open access: yesBritish Journal of Pharmacology, EarlyView.
Cancer is frequently accompanied by cachexia, a systemic syndrome characterized by progressive loss of skeletal muscle mass, with or without loss of fat mass. Increasing evidence indicates that cancer can also induce cardiac muscle wasting, which is associated with structural cardiac remodelling, impaired contractile function and the development of ...

Polyphosphate kinase from Propionibacterium shermanii. Demonstration that polyphosphates are primers and determination of the size of the synthesized polyphosphate.

open access: yesJournal of Biological Chemistry, 1987
Polyphosphate kinase from Propionibacterium shermanii was purified to 70% homogeneity and shown to be a monomeric enzyme of molecular weight 83,000 +/- 3,000. It was demonstrated that short chains of polyphosphate serve as primers by using [32P]polyphosphate, 6-80 residues in length for synthesis of long-chain polyphosphate glucokinase, the radiolabel ...

Common pathways and outliers in glucose catabolism across Trypanosomatidae

open access: yesThe FEBS Journal, EarlyView.
Trypanosomatid parasites, including Trypanosoma sp., Leishmania sp., Phytomonas sp., and Vickermania sp., share a common motif: a metabolism built around the glycosome, a unique peroxisome‐derived organelle housing the first steps of glycolysis. Yet, these organisms have evolved remarkably diverse strategies to catabolize glucose, excreting distinct ...

Inorganic Polyphosphate Is in the Surface of Trypanosoma cruzi but Is Not Significantly Secreted

open access: yesPathogens
Trypanosoma cruzi is the etiologic agent of Chagas disease, an infection that can lead to the development of cardiac fibrosis, which is characterized by the deposition of extracellular matrix (ECM) components in the interstitial region of the myocardium.
