Research on room temperature phosphorescence (RTP) of metal-organic frameworks (MOFs) has been rapidly developed in recent years. However, it is still challenging to realize long-wavelength RTP (>580 nm). In this article, a new strategy is proposed to achieve the red-shifted RTP through constructing dual-ligand MOFs.

Synthesis of high-molecular-weight polypeptides and their block copolymer macromolecular architectures from β-sheet-promoting L-amino acids is still an unresolved problem. Here, an elegant steric hindrance-assisted ring-opening polymerization (SHAROP) strategy is introduced to access β-sheet poly(L-tyrosine) having more than 250 units. The scope of the synthetic methodology is expanded to access unexplored poly(L-tyrosine)-based higher-order β-sheet block copolymer nanoassemblies.

Guidance and control of multiple unmanned surface vehicles (Multi-USVs) present many challenges due to their under-actuation and the unknown environmental disturbance. This research addresses the formation guidance and control problems of multi-USVs by designing a global fixed-time constrained guidance and control formation approach. First, a global fixed-time control Lyapunov function (GFCLF) is proposed using an innovative shift function to deal with the fixed-time output partial constraint.

Statement Of Problem: Early childhood caries is one the world's most common problems in infants and treatment of posterior teeth with esthetic crowns in a low rate of wear on opposite dentition is a challenge for pediatric dentists.
Purpose: The purpose of this in vitro study was to evaluate the wear behavior of the tooth colored crown materials and the opposing teeth in using different esthetic crown materials in the mixed dentition period.
Material And Methods: The following tooth type and crown materials were considered in the experiment.

Statement Of Problem: Extraoral photogrammetry (PG) systems can record implant positions in 1 scan or in 2 scans that are then merged. However, the accuracy of implant positions recorded in 2 partial photogrammetry scans is unknown.
Purpose: The purpose of this in vitro study was to compare the accuracy of complete arch implant scans recorded in 1 or 2 scans by using 3 extraoral PG systems.
