The adsorption structures of dimethyl ether (DME) on silicalite-1 zeolite (MFI-type) are determined using single-crystal X-ray diffraction. The structure of low-loaded DME-silicalite-1 indicates that all DME molecules are located in the sinusoidal channel, which is the most stable sorption site based on the van der Waals interaction between DME and the framework. The configuration of guest mole...

PURPOSE To examine the comorbidity profile and update estimates of health care resource utilization for commercially insured, working-age adults with diabetic macular edema (DME) relative to a matched comparison group of diabetic adults without DME. Additional comparisons were made in the subgroup of pseudophakic patients. PATIENTS AND METHODS A retrospective matched-cohort study of commercia...

Seed-assisted low alkalinity gel system was developed to explore the organic-free synthesis of MOR zeolite. nanoassemblies with Si/Al ratio (SAR) up 9.4 and high solid yield (84–94%) were successfully obtained under controlled conditions. Characterization results demonstrate that acid strength increases in parallel SAR, while total amount proton distribution main channels side pockets are simil...

Liquid fuels like dimethyl-ether (DME), produced from biomass and electricity are crucial for decarbonizing the shipping industry. In this work, production of DME wheat straw through gasification is presented. It was shown how process can be optimized by using 1) two-stage instead one-stage synthesis, 2) partial oxidation gas 3) a hydrogen quench high-temperature reverse water shift reactions. ...

Converting syngas into ethanol (EtOH) is highly attractive but remains challenge. Dimethyl ether (DME) carbonylation with CO to methyl acetate (MA) on zeolite and its further hydrogenation EtOH Cu-based catalyst open a new synthesis route from syngas. In this work, nano-sized ZSM-35 (NZ35) zeolite, possessing abundant active sites porosity short diffusion path, found realize much better activit...

IMPORTANCE Diabetic macular edema (DME) is a leading cause of vision loss in persons with diabetes mellitus. Although there are national estimates for the prevalence of diabetic retinopathy and its risk factors among persons with diabetes, to our knowledge, no comparable estimates are available for DME specifically. OBJECTIVES To estimate the prevalence of DME in the US population and to iden...

Introduction Emergency Medicine (EM) is a unique clinical learning environment. The American College of Graduate Medical Education Clinical Learning Environment Review Pathways to Excellence calls for "hands-on training" of disclosure of medical error (DME) during residency. Training and practicing key elements of DME using standardized patients (SP) may enhance preparedness among EM residents ...

PURPOSE To quantify dose mapping errors (DMEs) of a point-based dose mapping method for 4D lung treatment plans. METHODS Point-based dose mapping methods utilize deformation vector fields (DVFS) to interpolate dose from a deformed image. Volume-based dose mapping methods consider the volume overlap between deformed and reference voxels; defining dose as the integral energy divided by the inte...

PURPOSE To assess the impact of diabetic retinopathy (DR) and diabetic macular edema (DME) on health-related quality of life (HRQoL) in type 1 and type 2 diabetes using the EuroQoL EQ-5D generic multi-attribute utility instrument (MAUI). METHODS In this cross-sectional study, 577 patients with diabetes were recruited from specialized eye clinics in Melbourne, Australia. Each patient underwent...
