Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

open access: yesAdvanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]

open access: yes, 2007
Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To

Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

open access: yesAdvanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

High Serum Concentration of Interleukine-6 and Rank-ligand as Risk Factors for Osteoporosis in Estrogen Deficiency Post-menopausal Women [PDF]

open access: yes, 2009
Osteoporosis in post-menopausal women is not merely due to deficient estrogenhormone production. The development of osteoporosis is due to increased boneresorption by osteoclasts. The osteoclast\u27s number and activity is controlled by activatingfactors

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

open access: yesAdvanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...

Remember the periroot sheet in orthodontic treatment of ectodermal dysplasia patients

open access: yesDental Hypotheses, 2014
Introduction: Root resorption has various etiologies. Recent studies have demonstrated a periroot sheet covering the root. The outermost layer of this sheet is the Malassez′ epithelial layer. Tooth malformations are seen in ectodermal dysplasia and it is

Microrelief of Rounded Diamond Crystals as an Indicator of the Redox Conditions of Their Resorption in a Kimberlite Melt

open access: yesCrystals, 2020
We conducted a detailed study of the morphology of diamond crystals partially dissolved in a water-bearing kimberlite melt at pressure of 6.3 GPa, temperature of 1400 °C, and two oxygen fugacities (fO2) corresponding to the Re-ReO2 buffer and near ...

A Mechanistic Blueprint for Fast, High‐Yield Green Scintillators Using Conjugated Polymer–Nanocrystal Composites

open access: yesAdvanced Functional Materials, EarlyView.
Conjugated polymer–nanocrystal composites are investigated to develop fast, high‐yield green scintillators. The polymer F8BT enables efficient, ultrafast emission, while blends with non‐emitting HfO2 nanocrystals and luminescent CdZnS/ZnS quantum dots reveal distinct sensitization mechanisms.
