Sexual Risks in Young Patients in Inpatient Child and Adolescent Psychiatric and Psychotherapeutic Addiction Treatment Engaging in fulfilling and low-risk sexual relationships is a developmental task in adolescence and young adulthood. At the same time, sexual contact is associated with risks, including early and/or unwanted pregnancies, sexually transmitted infections (STIs) and negative sexual experiences. In the present study, n = 84 inpatients in child and adolescent psychiatric and psychotherapeutic addiction treatment aged between 13 and 19 years were examined.

- The study focuses on how interfacial ion insertion affects the performance of lithium-ion batteries, particularly in two-dimensional layered-oxide particles.
- The research reveals that the varying insertion rates across channels are influenced by unclear crystal orientation and lithium diffusion lengths, making it challenging to understand the activation of insertion channels.
- Using a specially fabricated single-crystal thin film, the researchers found heterogeneity in lithium concentration during insertion, which worsens with higher current density, offering essential insights for improving battery design and longevity.
Article Synopsis
- Cations like potassium (K) play a crucial yet debated role in the CO electroreduction reaction, influencing its mechanism.
- A study using a Ni-N structure shows that K alters the rate-determining step of the reaction, supported by in-situ X-ray and Raman spectroscopy data.
- This interaction between K and CO stabilizes chemisorbed CO, shifting the reaction pathway to favor CO electroreduction over hydrogen evolution, thus lowering the energy barrier.
Crosstalk, the exchange of chemical species between battery electrodes, significantly accelerates thermal runaway (TR) of lithium-ion batteries. To date, the understanding of their main mechanisms has centered on single-directional crosstalk of oxygen (O) gas from the cathode to the anode, underestimating the exothermic reactions during TR. However, the role of multidirectional crosstalk in steering additional exothermic reactions is yet to be elucidated due to the difficulties of correlative in situ analyses of full cells.
