Teaching of Engine‐Driven Root Canal Treatment Globally—A “Questionnaire Based” Study

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Objectives The teaching of root canal therapy, particularly engine‐driven root canal preparation, varies across dental schools. Therefore, this qualitative, questionnaire‐based study aimed to identify preferred engine‐driven endodontic systems at top‐ranked dental universities and to explore the reasons behind their selection.

Fluorenone and Fluorenemalononitrile‐Tethered Conjugated Microporous Polymers for Efficient CO2 Uptake and Rhodamine B Removal

open access: yesMacromolecular Rapid Communications, EarlyView.
TPET‐F2CN CMP exhibited higher CO2 uptake (2.88 mmol g−1 at 273 K) and superior Rhd B adsorption, with an equilibrium capacity of 98.12 mg g−1 and a maximum monolayer capacity of 155.6 mg g−1. ABSTRACT Herein, two conjugated microporous polymers (CMPs), TPET‐FO and TPET‐F2CN, are functionalized with carbonyl and nitrile groups.

Resonant two-photon ionization spectra of van der Waals complexes: O-, m- and p-C6H4R2...N2 (R≡F, CH3)

open access: yes, 1997
The jet-cooled van der Waals (vdW) complexes o-, m- and p-C6H4R2...N2 were studied by the one-colour resonant two-photon ionization technique (R2PI) through the S1←S0 transition around the 0̄00 band.

Mechanical Performance Retention of CNT‐Modified Sisal Biocomposites Under Hygrothermal‐Saline Aging

open access: yesPolymer Composites, EarlyView.
Mechanical Performance Retention of CNT‐Modified Sisal Biocomposites Under Hygrothermal‐Saline Aging. ABSTRACT This study investigates the influence of carbon nanotubes (CNTs) on the moisture absorption kinetics and mechanical degradation of discontinuous random fiber (DRF) biocomposites under accelerated hygrothermal–saline (HTS) aging.

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3

open access: yesSmall, EarlyView.
Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...
