Copper and zinc are elements commonly used in industrial applications as aqueous solutions. Before the solutions can be discharged into civil or native waterways, waste treatment processes must be undertaken to ensure compliance with government guide

We investigated the fabrication of an optical-fiber oxygen sensor based on luminescence quenching of a ruthenium (II) complex for our optical-fiber-sensor arrays. Sensor regions are located between two optical fibers forming orthogonal fiber-fiber ju

A highly porous optical-fiber cladding was developed for evanescent-wave fiber sensors, which contains sensor molecules, maintains guiding conditions in the optical fiber, and is suitable for sensing in aqueous environments. To make the cladding mate

One theme that both the American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) agree pervades any science course (and specifically chemistry) is scale. Despite the fact that scale concepts and skills are at

Assessment and evaluation tools and instruments are developed to measure many things from content knowledge to misconceptions to student affect. The standard validation processes for these are regularly conducted and provide strong evidence for the v

A new evanescent-wave fiber sensor is described that utilizes absorption-modulated luminescence (AML) in combination with a crossed-fiber sensor platform. The luminescence signals of two crossed-fiber reference regions, placed on opposite sides of th

Scale as a theme in science instruction is not a new idea. As early as the mid-1980s, scale was identified as an important component of a student’s overall science literacy. However, the study of scale and the scale literacy of students in varying

An important component of a student’s science literacy is scale and concepts relating to scale including proportion and quantity. Measuring a student’s scale concept has been examined using laboratory studies with one-on-one activities and interv

Within a host molecular system, such as cofactors in proteins, active sites in metal–organic frameworks, and dopants in semiconductor solids, a guest molecule experiences a very specific environment that includes interaction with electrostatic forc

Hole-burning spectroscopy, a high-resolution spectroscopic technique, allows details of heterogeneous nano-environments in biological systems to be obtained from broad absorption bands. Recently, this technique has been applied to proteins, nucleic a
