The focus of this study was to observe the mechanical properties of bamboo plastic composites (BPCs) with bamboo pulp fiber (BPF) or white mud (WM). The essential work of fracture (EWF) methodology was used to characterize the impact toughness of BPCs. The results revealed an increase in flexural, tensile and impact properties, when adding the BPF in the BPCs. While the flexural properties of WM-reinforced BPCs revealed increasing, there was a decrease in tensile and impact strength. In an impact strength analysis study, BPF-filled BPCs showed excellent impact property over WM-filled BPCs; scanning electron microscopy (SEM) helps to explain impact fracture behavior of BPCs. EWF analysis of impact results showed that the specific essential work of fracture () increased significantly with the amount of BPF used in BPCs but decreased with the increase of WM in the BPCs. There was similar variation for the non-essential plastic work () of BPCs. This result indicates that the fracture initiation and fracture propagation of BPCs are different.

Copper radioisotopes can be used for imaging as well as for therapy and, thus, can form ideal theranostic pairs. The Cu(II) complexes of cross-bridged cyclam (cb-cyclam) derivatives are considered to be highly stable . However, the complexes are mostly formed under harsh conditions not compatible with sensitive biomolecules.

Methods: A total of 172 patients met inclusion criteria for this study. Patient-reported outcomes including patient-reported wrist/hand evaluation (PRWHE), single assessment numeric evaluation, and PRO measurement information system (PROMIS) global-10 questionnaires were collected prospectively and stored in an electronic data capture system until review for the purpose of this study.

Selenium (Se), released from mining, power generation, and agriculture, is an environmentally and ecologically concerning contaminant due to its toxicity at elevated concentrations. Se oxyanions are highly soluble and mobile in aquatic ecosystems, and have a strong tendency to bioaccumulate and biomagnify, leading to acute and chronic toxicity in animals and humans. Photocatalysis presents a promising sustainable Se treatment solution and has successfully reduced and removed Se from mining-influenced matrices using UV-powered slurry photoreactor systems.
