Front Cover: In article number 2000754, Susan M. Kelleher and co-workers outline an accessible scalable method for polyethylene glycol (PEG)-tapered nanopillar array production. Photopolymerisation of acrylateterminated polypropylene (PPG) PEG monomeric/photoinitiator cocktails is utilised to cast high fidelity replicas silicon arrays. this way, rapid prototyping polymeric nanostructured surfac...

This paper reported the experimental testing of a triangular and conventional basin solar still (TBSS CBSS). Solar absorber are made glass polyethylene cover, respectively, with an area 0.25 m2. Square same m2 square cover for condensation was fixed. Experimentations were conducted during month December 2018, different natural criteria such as intensity, wind speed, surrounding ambient temperat...

the seasonal diversity and distribution of microphytes and macrophytes in 40 artificial irrigationponds constructed in a semi-arid region, and the most suitable conditions to maintain these enclaves asbiodiversity spots were studied for the first time. a total of 104 species were detected. bacillariophyta,cyanobacteria and chlorophyta dominated both pelagic and benthic microphytic communities, ...

Objective(s): The use of new technologies, which can be realized as nanotechnology, is a novel approach in this sector. Covers made of silver nanoparticles effectively prevent and reduce invasion of microorganisms, compared with other conventional covers. This study was conducted to determine the effects of nanosilver covers in comparison with other conventional covers. <stron...

Introduction: Polyethylene wear particles induce macrophages to release cytokines, which can lead to osteolysis and aseptic loosening of total joint prostheses. The generation of polyethylene wear particles is one of the most important factors that affect the midterm and long-term clinical results associated with total knee arthroplasty (TKA). Therefore, to achieve better long-term results for ...

INTRODUCTION Reconstruction of cranial defects is an essential component of skull base surgery as it aids in restoring functionality, providing coverage of intradural structures, and achieving optimal cosmesis. In acoustic neuroma surgery, tumor removal and subsequent reconstruction of the skull base defect are equally important elements. All three approaches utilized in acoustic neuroma surger...
