“…Moreover, we find an approximate 8-fold rotational symmetry, whereas the symmetry of phthalocyanines themselves is 4-fold. This may be attributed to fluctuations of the molecule between two orientations as previously reported in a number of cases. − …”

Large ordered islands of aluminum phthalocyanine (AlPc) molecules, which are unstable in air, are synthesized from ClAlPc on Pb(100) via dechlorination. Low-temperature scanning tunneling microscopy reveals that isolated AlPc molecules lose their spin moment on superconducting Pb(100). Molecular magnetism, which is detected via Yu–Shiba–Rusinov (YSR) resonances, may be restored by surrounding a molecule with an array of neighbor molecules in artificial arrays or in a self-assembled monolayer. Unlike phthalocyanine (H2Pc) or lead phthalocyanine (PbPc) monolayers, where the YSR energy was found to depend strongly on the detailed configuration of the neighboring molecules, we find a similar magnetic moment on every second molecule for AlPc. In addition, YSR resonances lead to unusually high conductance peaks that are due to vibrational excitations. Twelve vibrational modes are resolved and discussed with respect to similar results from PbPc. The enhancement of the inelastic transitions is tentatively attributed to the large amplitude of the YSR resonances and the long lifetime of electrons in the molecular bound state. By assembling neighboring molecules into configurations that differ from those of the monolayer, the YSR energy may be fine-tuned, and a simple spin-state switching device is constructed.

Introduction:Child abuse and neglect is a widespread and pressing issue, with serious and long-term adverse effects on children's physical and psychological health. Pediatricians play a crucial role in detecting and addressing cases; however, studies have shown challenges in reporting cases encountered in clinical practice. This study aims to examine pediatricians' attitudes towards reporting cases of child abuse and neglect encountered in their clinical practices, as well as the factors influencing these attitudes. Materials and Methods: A descriptive cross-sectional study was conducted among pediatricians in Istanbul. Data collected included sociodemographic characteristics, knowledge and formal training about child neglect and abuse, attitudes about dealing with it, experience, and reporting behavior. The data was collected through a self-administered online questionnaire. The study provides insights into the current awareness and response of Istanbul's pediatricians towards child neglect and abuse. The data were analyzed using SPSS 22, employing descriptive and comparative statistics such as frequency, mean, standard deviation, and correlation tests. Ethical approval was obtained from the Istanbul Medipol University Ethics Committee. The study was conducted in accordance with the Declaration of Helsinki and online consent was obtained from the participants. Results: The study involved 126 pediatricians. Results showed that pediatricians had generally positive attitudes toward reporting child neglect and abuse. Gender and marital status did not significantly influence attitudes, but pediatricians who were parents scored higher on reporting Responsibility. Additionally, it was shown that those with more professional experience had a higher reporting responsibility score. Structured training on child abuse and neglect has been shown to increase pediatricians' reporting responsibility scores and exhibit less anxious attitudes. Conclusion:This study highlights pediatricians' positive attitudes toward reporting child abuse and neglect and identifies influencing factors such as training, professional experience, and collaboration. It emphasizes the importance of addressing challenges like awareness of reporting procedures and concerns about negative consequences. Comprehensive training, clear reporting protocols, and multidisciplinary collaboration are essential for increasing reporting rates and improving the detection of child abuse and neglect. The study contributes to enhancing child protection systems in Turkey by providing insights into pediatricians' attitudes toward reporting child abuse and neglect.
