If possible, all surfaces painted with lead-based paint should be abated by replacement, encapsulation, or paint removal. Ordinary paint is never an appropriate encapsulant; it is only part of a temporary maintenance procedure. Encapsulation materials should be durable and, where possible, affixed with both fasteners and adhesive. Paintlike coatings should be used with caution. Only coatings an...

The technique of tailoring the complex refractive index of an artificial dielectric material has been developed at the University of Lowell Research Foundation (ULRF). Low reflection coatings, generally referred to as Dällenbach layers, have been designed for metal substrates using the artificial dielectric. The method of characterizing materials for the purpose of tailoring their dielectric pr...

A facile process is introduced to flake high aspect-ratio anodic TiO(2) nanotube (TiNT) arrays off Ti substrates and then chemically remove the bottom caps to obtain open-ended TiNT films that exhibit high activity to photocatalytic degradation of methylene blue and efficient hydrogen production from photoelectrocatalytic water splitting.

Two kinds of Bi2Se3 nanostructures, 3D rose-like hierarchitectures and monodisperse nanospheres, have been synthesized through adjusting the supersaturation of the precursor solution. Noticeable hydrogen storage capacity, amounting to 185 mA h g-1, has been found for the 3D rose-like hierarchitectures, which arises from the special micro/nano-hierarchitectures with highly crystallized flake-sub...

The industrial demand for functional filaments made of bio-sourced, biocompatible, biodegradable, and/or recyclable polymers and composites material extrusion (MEX) 3D printing is continuously growing. Polylactic acid (PLA), the most popular filament, combines such properties, yet its reinforcement with low-cost, inert, recycled fillers remains challenging. Herein, glass in three different micr...

As 2D materials (2DMs) gain the research limelight as a technological option for obtaining on-demand printed low-cost integrated circuits with reduced environmental impact, theoretical methods able to provide necessary fabrication guidelines acquire fundamental importance. Here, multiscale modeling technique is exploited study electronic transport in devices consisting of 2DM network flakes. Th...
