Lead-free halide double perovskite nanocrystals (DPNCs) are emerging materials, recently explored as potential candidates in light-emitting, photovoltaic, and other optoelectronic applications. This Letter reveals unusual photophysical phenomena and nonlinear optical (NLO) properties of Mn-doped CsAgInCl nanocrystals (NCs) via temperature-dependent photoluminescence (PL) and femtosecond Z-scan measurements. The PL emission measurements suggest that self-trapped excitons (STEs) are present, and more than one STE state is possible for this doped double perovskite.

CsAgInCl double perovskite (DP) nanocrystals (NCs) are an emerging class of materials with promising application potential in photonics/optoelectronics owing to their nontoxicity, direct bandgap, and high thermal and moisture stability. These NCs are, however, rarely explored for nonlinear optical (NLO) applications. Herein, we present a comprehensive investigation of the photophysical and nonlinear optical properties of erbium- (Er) and ytterbium (Yb)-doped CsAgInCl nanocrystals (denoted as Er-DP and Yb-DP, respectively).

Article Synopsis
  • Adductor canal block (ACB) is useful for pain relief after total knee arthroplasty (TKA), but it doesn't target pain in the back part of the knee; this study compares two additional techniques, IPACK and SPANK blocks, for better pain control.
  • The research involved 82 patients split into two groups receiving ACB combined with either IPACK or SPANK, measuring pain scores, opioid use, and patient satisfaction from 6 to 48 hours post-surgery.
  • Results showed that the IPACK group had significantly better pain relief, lower opioid use, and higher patient satisfaction than the SPANK group, while knee rehabilitation outcomes were similar for both.

Objective: The antibacterial property of coconut, the presence of lauric acid, and the ability to extract antimicrobial peptides Cn-AMP (1, 2, and 3) from tender coconut water has drawn attention on its effectiveness in normal consumption. An experimental study was conducted to evaluate the antimicrobial efficacy of tender coconut water in its natural state on .

Materials And Methods: Fresh tender coconut water and pasteurized tender coconut water were taken as test samples, dimethyl formamide was used as the negative control, and 0.
