Published: October 2010

A functionalized polymer film allowing for a complete and straightforward second-harmonic generation (SHG)-assisted high-contrast writing-reading-erasing-writing sequence is proposed. The whole process is supported by the reversible photoinduced dimerization of a coumarin chromophore and enables efficient optical data storage that can be detected only by SHG imaging.

Cushing's syndrome related to higher rates and earlier onset of cataract: A nationwide retrospective cohort study.

Graefes Arch Clin Exp Ophthalmol

January 2025

School of Medicine, Faculty of Medical and Health Sciences, Tel Aviv University, Tel Aviv, Israel.

Purpose: To investigate the risk of cataract in patients with Cushing's syndrome (CS) and evaluate whether disease onset occurs at an earlier age compared to general population.

Methods: A nationwide retrospective matched-cohort study including individuals diagnosed with endogenous CS from 2000 to 2023. Patients with CS were matched in a 1:5 ratio with a control group individually matched for age, sex, socioeconomic status, and body mass index.

Theoretical Study on the Kinetics of Secondary Oxygen Addition Reactions for N-Butyl Radicals.

Chemical kinetics for second oxygen addition reactions (·QOOH + O) of long-chain alkanes are of great importance in low-temperature combustion technologies. However, kinetic data for key reactions of ·QOOH + O systems are often difficult to obtain experimentally and are primarily estimated or calculated by using theoretical methods. In this work, barrier heights (BHs), reaction energies (Δs), and relative energies (REs) of stationary points for key reactions of two representative ·QOOH + O systems in the low-temperature oxidation of -butyl as well as pressure-dependent rate constants for the involved reactions are calculated with the high-level quantum chemical method CCSD(T)-F12b/CBS.
