Hydrosilylation of olefins activated on highly Lewis-acidic calcium cation
Chemistry. 2024 Apr 25:e202401322. doi: 10.1002/chem.202401322. Online ahead of print.ABSTRACTThe report introduces simple yet highly reactive calcium salt, Ca[Al(ORF)4]2 (RF = C(CF3)3), 1, which effectively catalyses olefin hydrosilylation through an unusual mechanism involving the activation of the alkene molecule. Upon dissolution in o-difluorobenzene (oDFB), 1 forms a highly Lewis acidic [Ca(oDFB)6]2+ complex. Our DFT calculations reveal that fluoride ion affinity is comparable to SbF5. Reactivity tests show that it effectively catalyses the hydrosilylation of olefins with high regioselectivity, also in reactions invol...

The Effect of Direct Observation of Procedural Skills on Learning and Satisfaction of Students in Community Dentistry Course
CONCLUSION: The DOPS method had more impact on Fluoride therapy, pit and fissure sealant therapy, and health education's learning process in dentistry students than the conventional evaluation. The professors and students' satisfaction level was high regarding DOPS. The advantages of the DOPS method are student-centeredness, objectivity, and appropriate feedback.PMID:38660432 | PMC:PMC11036320 | DOI:10.30476/JAMP.2023.100431.1890 (Source: Adv Data)

Spatial Atlas for Mapping Vascular Microcalcification Using 18F-NaF PET/CT: Application in Hyperphosphatemic Familial Tumoral Calcinosis
CONCLUSIONS: This technique affords the ability to visualize spatial patterns of the active microcalcification process in the peripheral vasculature. Further, this technique affords the ability to track microcalcifications at precise locations not only across time but also across subjects. This technique is readily adaptable to other diseases of vascular calcification and may represent a significant advance in the field of vascular biology.PMID:38660800 | DOI:10.1161/ATVBAHA.123.320455 (Source: Arteriosclerosis, Thrombosis and Vascular Biology)

High ‐Level Disordered Metal–Organic Frameworks Synthesized by Interference‐Oriented Attachment for Electrochemical Anion Sieve
This study pioneers the use of the interference-oriented attachment (IOA) mechanism to meticulously craft the morphology and crystal growth of MIL-101(Cr) (Cr-MOF), resulting in the successful synthesis of a high-level disordered Cr-MOF boasting an enhanced array of active sites and exceptional electrochemical properties. The correlation between disordered structures and the electrochemical properties of MOFs are elucidated using the lattice distortion index and fractal dimension. The high-level disordered MOF electrode showcases a remarkable fluoride sieving effect, outperforming conventional fluoride removal materials wi...

Sensors, Vol. 24, Pages 2694: Polymer Nanocomposite Sensors with Improved Piezoelectric Properties through Additive Manufacturing
Daewon Kim
Additive manufacturing (AM) technology has recently seen increased utilization due to its versatility in using functional materials, offering a new pathway for next-generation conformal electronics in the smart sensor field. However, the limited availability of polymer-based ultraviolet (UV)-curable materials with enhanced piezoelectric properties necessitates the development of a tailorable process suitable for 3D printing. This paper investigates the structural, thermal, rheological, mechanical, and piezoelectric properties of a newly developed sensor resin material. The polymer resin is based on polyviny...
