The emergence of solid-state battery technology presents a potential solution to the dissolution challenges of high-capacity small molecule quinone redox systems. Nonetheless, the successful integration of argyrodite-type LiPSCl, the most promising solid-state electrolyte system, and quinone redox systems remains elusive due to their inherent reactivity. Here, a library of quinone derivatives is selected as model electrode materials to ascertain the critical descriptors governing the (electro)chemical compatibility and subsequently the performances of LiPSCl-based solid-state organic lithium metal batteries (LMBs).

Their PL peaks were located at ∼8 μm at 10 K with a full width at half maximum (FWHM) of 10 meV. Using the temperature-dependent FWHM values, we obtained carrier-phonon coupling coefficients for PbSe.

Distinct bandedge PL emission was observed in the whole temperature range between 10 and 300 K, indicating the high optical quality of these nanostructures. The PL peak of the nanosheets was found at 0.

- A survey was conducted to evaluate the usability of the third edition of the Korean breast cancer clinical practice guidelines, involving 100 questionnaires sent to over 700 members of the Korean Breast Cancer Society.
- Out of the 270 respondents, 96 completed the questionnaire, which covered various aspects of breast cancer, including benign and metastatic diseases, with a focus on the differences in clinical evidence levels required for recommendations compared to the previous guidelines.
- The guideline committee is encouraged to strengthen the development process through clinical trial data, a multidisciplinary approach, regular updates, and discussions, aiming for improved cost-effectiveness and optimal decision-making in breast cancer treatment.
The amplification and overexpression of Her2 proto-oncogene have been found to be associated with the development and progression of human breast cancer. A polymorphic valine allele at codon 655 of the Her2 gene (Her2(V655)) was suggested by some authors to be a susceptible genetic factor for the development of breast cancer. The Her2 polymorphism at codon 655 was investigated in 304 Korean women including 177 patients with breast cancer.
