Background: Following the new line of research on Family Social Capital, this work focused on the adaptation and application of the Family Social Capital questionnaire to studying the association between Family Social Capital (FSC) and the intention of Russian females to start a business.

Objective: This study investigated the relationship between three dimensions of Family Social Capital (Structural, Cognitive, and Bonding) and components of Entrepreneurial Intention (EI) operationalized via Ajzen's Theory of Planned Behavior among females in Russia.

Design: Online survey participants (N=222) were assessed with 1) an adapted version of the FSC questionnaire (Álvarez et al.

Low back pain occupies one of the leading places among pain syndromes and is an urgent medical, social, and economic problem of our time. A review of modern domestic and foreign literature data on the features of diagnosis, treatment and rehabilitation of chronic dorsalgia in patients with comorbid pathology was carried out. The article reflects the main etiological factors, describes the types of back pain: non-specific (musculoskeletal), radiculopathy, pain associated with potentially dangerous diseases, in addition, issues of the pathogenesis of pain syndromes are highlighted with an indication of nociceptive, neuropathic, psychogenic components.

A general synthesis approach of aqueous glutathione-capped ternary Ag-In-S, Cu-In-S, and Hg-In-S nanocrystals (NCs) is introduced, allowing the NC composition to be varied in a broad range. Ternary Hg-In-S (HIS) NCs are reported for the first time and found to have the same tetragonal chalcopyrite motif as Cu-In-S and Ag-In-S NCs, corroborated by phonon spectra, while X-ray photoelectron spectroscopic data indicate mercury to be present as Hg in the Hg-In-S NCs. Colloidal HIS and Hg-In-S/ZnS NCs showed little or no variations of the spectral width of the photoluminescence band upon NC size selection, temperature variation in a broad range of 10-350 K, deposition of a ZnS shell, or postsynthesis annealing.

Article Synopsis
  • The study examines how the photoluminescence (PL) intensity of colloidal semiconductor nanocrystals (NCs) changes with temperature, specifically focusing on GSH-capped Ag-In-S (AIS) NCs and their AIS/ZnS core/shell structures.
  • Both core and core-shell NCs show significant PL quenching when heated from 10 to 80 °C, which reverses upon cooling, attributed to the breakdown of ligand-metal complexes and the presence of water.
  • The thermal PL quenching mechanism demonstrates increased temperature sensitivity for these NCs compared to others, suggesting their potential use as luminescent nano-thermometers for precise temperature sensing in bio-sensing applications.
