Photoswitchable Conductive Metal–Organic Frameworks

Advanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Color stability of facial prostheses

The Journal of Prosthetic Dentistry, 1995
The limited service of facial prostheses is the result of degradation of the elastomer and color instability. Deterioration may be caused by many factors, which include environmental exposure and changes in humidity. This investigation assessed the efficacy of an additive, intrinsic, broad-spectrum ultraviolet light absorber on the color stability of a

Color stability of recent composite resins

Odontology, 2016
The objective of the study was to evaluate the color stability of 8 recently developed resin composites when exposed to various staining agents. Six disc-shaped specimens made out of 8 resin composite materials were immersed in artificial saliva, coffee, coke, tea, orange juice and red wine. The initial color (T0) of the 288 specimens was assessed by a

COLOR STABILITY OF BETANIN

Journal of Food Science, 1974
Some chemical and physical factors were evaluated for their effects on stability of betanin in model systems and in beet juice. Results indicate that the stability of betanin color is pH sensitive and generally is less than that of artificial dyes. The color of betanin is most stable between pH 4.0 and 6.0.

Color stability of provisional prosthodontic materials

The Journal of Prosthetic Dentistry, 2004
Discoloration of provisional prosthodontic materials may result in patient dissatisfaction and additional expense for replacement.The purpose of this study was to determine the color stability of 5 provisional prosthodontic materials before and after immersion in distilled water or coffee for 20 days or exposure to ultraviolet (UV) light for 24 hours.A

Color stability of temporary restorative materials

The Journal of Prosthetic Dentistry, 1979
In this study it was shown that: 1. There was a statistically significant initial color difference in materials labeled shade 65. 2. Rough materials darkened significantly more than polished materials. 3. There was not statistically significant over all difference in the amount of staining between air-cured and pressure-cured samples. 4.

COLOR STABILITY OF PEELED 'SARIASLAMA' CHESTNUTS

Acta Horticulturae, 2014
The potential use of citric acid, ascorbic acid and Na-metabisulphite for the control of browning of peeled 'Sariaslama' chestnut was investigated. 'Sariaslama' chestnuts were dipped into solutions of 0, 1, 2 and 4 mM citric acid, ascorbic acid and Na-metabisulphite, placed in trays over-wrapped with plastic film and stored at 4 degrees C for 10 d ...
