Density functional theory study of promising polyene-diphenylaniline organic chromophores for dye-sensitized solar cell applications

open access: yesCogent Engineering, 2018
Dye-sensitized solar cells have attracted rapid interest over the recent years with prospect of emerging as a viable alternative to conventional silicon-based solar cells. Currently organic and inorganic complexes have been widely employed as sensitizers

THE ABSORPTION OF ULTRAVIOLET IONIZING RADIATION IN GASES

open access: yes, 1956
The sparking probability of a test gap, to which short-duration direct high voltage pulses are applied, is shown to depend on the distance of the gap from a source of short wavelength, ultraviolet radiation. The radiation is restricted to a small volume

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

Towards trace gases detection in the UV range by coupling Dual Comb Spectroscopy and Integrated Path Lidar [PDF]

open access: yesEPJ Web of Conferences
Detecting reactive traces gases in the atmosphere requires fast acquisition time and in-situ probing without air sampling. Several trace gases present a maximum absorption cross-section in the ultraviolet (UV) range, which call for a spectrally-resolved ...

Effects of optical absorption in deep ultraviolet nanowire light-emitting diodes

open access: yes, 2018
We report our study on the effect of optical absorption in nanowire ultraviolet light-emitting diodes (LEDs) using three-dimensional finite difference time domain simulation. Utilizing nanowire structures can avoid the emission of guided modes inside LED

The relation of mesomeric effects and ultraviolet light absorption data. [PDF]

open access: yes, 1956
A method for the determination of mesomeric effects from ultraviolet light absorption data is critically discussed. For halogen-substituted compounds, the method gives an order of mesomeric effects different from that which is usually accepted for the ...

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

open access: yesAdvanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Ultraviolet Absorption Spectra of Para-Bromoanisole [PDF]

open access: yes, 1972
The ultraviolet absorption spectra of para-bromoanisole have been photographed in the vapour state and in solution in cyclo-hexane. In the vapour spectrum the absorption band at 34845 cm-1 is assigned as the 0,0 band.
