Physically Transient Photonics: Random versus Distributed Feedback Lasing Based on Nanoimprinted DNA

29-Sep-2014 | Andrea Camposeo; Pompilio Del Carro; Luana Persano; Konrad Cyprych; Adam Szukalski; Lech Sznitko; Jaroslaw Mysliwiec ..., ACS Nano, 2014

Room-temperature nanoimprinted, DNA-based distributed feedback (DFB) laser operation at 605 nm is reported. The laser is made of a pure DNA host matrix doped with gain dyes. At high excitation densities, the emission of the untextured dye-doped DNA films is characterized by a broad emission peak ...

Differential dyeing of wool fabric with metal‐complex dyes after ultraviolet irradiation

17-Sep-2014 | Gianluca Migliavacca, Franco Ferrero, Monica Periolatto, Coloration Technology, 2014

Experiments were conducted to investigate the ultraviolet irradiation of wool fabric as a pretreatment for differential dyeing. Wool fabric was irradiated using a medium‐pressure mercury lamp in order to obtain, on the irradiated area, increased dye uptake under the same dyeing conditions as ...

Prediction of recipes for cotton cationisation and reactive dyeing to shade match conventionally dyed cotton

17-Sep-2014 | Matthew J Farrell, Mary A Ankeny, Peter J Hauser, Coloration Technology, 2014

Cationisation allows cotton to be dyed with anionic dyestuffs (including anionic pigment dispersions) without the need for salt, and with decreased usage of dye, water, and energy. Appropriate cationisation levels play a part in dyeing properties such as fabric levelness, in fastness properties ...

Convenient Access to Carbohydrate–BODIPY Hybrids by Two Complementary Methods Involving One‐Pot Assembly of “Clickable” BODIPY Dyes (Eur. J. Org. Chem. 26/2014)

02-Sep-2014 | Mayra R. Martinez‐Gonzalez, Arlette Urías‐Benavides, Enrique Alvarado‐Martínez, J. Cristobal Lopez, Ana M. Gómez, Ma ..., European Journal of Organic Chemistry, 2014

The cover picture shows two concise, complementary, protocols for the one‐pot, three‐component assembly of an alkyne‐ or azido‐carbohydrate, 8‐thiomethyl BODIPY, and either propargylamine or an azido boronic acid, respectively, which allow access to fluorescent carbohydrate–BODIPY hybrids. ...

In Vivo Local Dye Electroporation for Ca2+ Imaging and Neuronal-Circuit Tracing

01-Sep-2014 | Nagayama, S., Fletcher, M. L., Xiong, W., Lu, X., Zeng, S., Chen, W. R., CSH Protocols, 2014

A major technical challenge for using optical imaging to analyze neuronal circuit functions is how to effectively load synthetic Ca2+ dyes or neural tracers into the brain. We introduce here a simple but versatile approach to label many neurons and clearly visualize their axonal and dendritic ...

Experimental and Theoretical Studies of Quadrupolar Oligothiophene‐Cored Chromophores Containing Dimesitylboryl Moieties as π‐Accepting End‐Groups: Syntheses, Structures, Fluorescence, and One‐ and Two‐Photon Absorption

28-Aug-2014 | Lei Ji, Robert M. Edkins, Laura J. Sewell, Andrew Beeby, Andrei S. Batsanov, Katharina Fucke, Martin Drafz, Judith A ..., Chemistry - A European Journal, 2014

Abstract Quadrupolar oligothiophene chromophores composed of four to five thiophene rings with two terminal (E)‐dimesitylborylvinyl groups (4 V–5 V), and five thiophene rings with two terminal aryldimesitylboryl groups (5 B), as well as an analogue of 5 V with a central EDOT ring (5 VE), have ...

Hierarchically porous graphitic carbon monoliths containing nickel nanoparticles as magnetically separable adsorbents for dyes

27-Aug-2014 | Yurong Liu, Baoping Lin, Dan Li, Xueqin Zhang, Ying Sun, Hong Yang, Journal of Applied Polymer Science, 2014

ABSTRACT The hierarchically porous graphitic carbon monoliths containing nickel nanoparticles (HPGCM‐Ni) were fabricated via multi‐component co‐assembly in polyurethane (PU) foam scaffold associated with a direct carbonization process from triblock copolymer F127, diblock copolymer PDMS‐PEO, ...
