In 2013, materials scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering grew...
A liquid nitrogen immersion cryostat has been developed for optical measurements. Liquid nitrogen in the sample chamber is kept free of bubbles and schlieren by the use of a cooling jacket of sacrific...
This paper describes a simple orbital picture for understanding the optical transitions and the second-order nonlinear optical response of metallocene-based chromophores of the form metallocene-(pi-br...
Garito and co-workers have suggested a mechanism to dramatically increase the second hyperpolarizability, gamma, in linear pi-electron-conjugated molecules. Polarization is introduced that leads to a ...
Eumelanin is a ubiquitous biological pigment, and the origin of its broadband absorption spectrum has long been a topic of scientific debate. Here, we report a first-principles computational investiga...
Accurate image-to-image registration is critical for many image processing workflows, including georeferencing, change detection, data fusion, image mosaicking, DEM extraction and 3D modeling. Users n...
The theory of polarizable anisotropic fluids is developed on the basis of a model fluid consisting of anisotropic Drude oscillators with embedded permanent dipoles. A matrix theory is developed. The d...
A pH optical sensor was developed based on the use of a mixture of Malachite Green Oxalate and Bromocresol Green indicators immobilized in a triacetylcellulose membrane, which had been previously hydr...
A pH optical sensor was developed based on the use of a mixture of Malachite Green Oxalate and Bromocresol Green indicators immobilized in a triacetylcellulose membrane, which had been previously hyd...
Three-dimensional models of seagrass canopies were constructed by treating leaves as flexible strips that fall under their own weight into naturalistic canopy structures. Canopy structures incorporate...
The response curves and sensor properties of silver-deposited optical fibers with Ag film thicknesses of 20.0 − 80.0 nm based on surface plasmon resonance (SPR) were investigated. The response o...
Capillary chromatography for the separation of optical isomers was developed using an untreated poly(tetrafluoroethylene) capillary tube and a water–hydrophilic/hydrophobic organic solvent mixture as ...
Three-armed poly(methyl methacrylate)[PMMA] was synthesized by atom transfer radical polymerization at 100 °C using benzene-1,3,5-triyl tris(4-(bromomethyl) benzoate as 3-armed initiator and a cuprous...
The electrochemical and optical properties of a novel conducting copolymer called poly(2,5'-dimethyl-[4-(2,5-di-thiophen- 2-yl-pyrrol-1-yl)-phenyl]azobenzene-co-(3,4-ethylenedioxythiophene)) (poly(1-c...
We characterized dissolved organic matter in La Caldera, an alpine lake in Sierra Nevada (Spain), and watersoluble organic compounds (WSOC) in dry and wet deposition originating from Saharan and marin...
