M/g-CN (M=Ag, Au, and Pd) composite: synthesis via sunlight photodeposition and application towards the degradation of bisphenol A.

In this work, natural sunlight successfully induced the deposition of gold (Au), silver (Ag), and palladium (Pd) nanoparticles (NPs) with 17.10, 9.07, and 12.

Sugarcane juice derived carbon dot-graphitic carbon nitride composites for bisphenol A degradation under sunlight irradiation.

Carbon dots (CDs) and graphitic carbon nitride (g-CN) composites (CD/g-CN) were successfully synthesized by a hydrothermal method using urea and sugarcane juice as starting materials. The chemical composition, morphological structure and optical properties of the composites and CDs were characterized using various spectroscopic techniques as well as transmission electron microscopy. X-ray photoelectron spectroscopy (XPS) results revealed new signals for carbonyl and carboxyl groups originating from the CDs in CD/g-CN composites while X-ray diffraction (XRD) results showed distortion of the host matrix after incorporating CDs into g-CN.

How orchestra members influence stage acoustic parameters on five different concert hall stages and orchestra pits.

Stage acoustic parameters aim to quantify the amount of sound energy reflected by the stage and hall boundaries and the energy decay over time. In this research, the effect of orchestra presence on parameter values is investigated. The orchestra is simulated by dressed mannequins, which have been compared with humans with respect to acoustic properties.

Safety of indwelling pleural catheter use in patients undergoing chemotherapy: a five-year retrospective evaluation.

Background: Indwelling pleural catheters (IPC) are increasingly becoming a first-line treatment in the management of malignant pleural effusions. Ambulatory management using IPC are increasingly used in this patient group whilst they are receiving concurrent chemotherapy. There are currently no prospective trials examining IPC safety in chemotherapy.

Measurements of speech intelligibility in common rooms for older adults as a first step towards acoustical guidelines.

Adapting the built environment to the needs of nursing- or care-home residents has become common practice. Even though hearing loss due to ageing is a normal occurring biological process, little research has been performed on the effects of room acoustic parameters on the speech intelligibility for older adults. This article presents the results of room acoustic measurements in common rooms for older adults and the effect on speech intelligibility.
