Dibenzoquinone Cyclopentadithiophene Diradicaloids Show Optical Transitions of Different Spin States and Anomalous Near‐Infrared Emission

Angewandte Chemie, Volume 137, Issue 2, January 10, 2025.
A series of bis(semiquinone) linearly π‐conjugated compounds with dithiophene bridges of different lengths were prepared that ranged from closed‐shell (the smallest) to full diradical (the longest) accompanied with narrow singlet‐triplet energy gaps (magnetic response).

Luminescence Thermometry on the Route of the Mobile‐Based Internet of Things (IoT): How Smart QR Codes Make It Real

Advanced Science, Volume 6, Issue 19, October 2, 2019., 2019
Organic–inorganic hybrid materials doped with Eu3+ and Tb3+ are processed asluminescent Quick Response (QR) codes, simultaneously doubling the storage capacity and sensing the temperature using a photo taken with a smartphone. The developed methodology yields a maximum relative thermal sensitivity of 5.14% · K−1 and a minimum temperature uncertainty of

Analytical Modelling of High Concentrator Photovoltaic Modules Based on Atmospheric Parameters

International Journal of Photoenergy, Volume 2015, Issue 1, 2015., 2015
The goal of this paper is to introduce a model to predict the maximum power of a high concentrator photovoltaic module. The model is based on simple mathematical expressions and atmospheric parameters. The maximum power of a HCPV module is estimated as a function of direct normal irradiance, cell temperature, and two spectral corrections based on air ...

RMS Current of a Photovoltaic Generator in Grid‐Connected PV Systems: Definition and Application

International Journal of Photoenergy, Volume 2008, Issue 1, 2008., 2008
This paper includes a definition of a new and original concept in the photovoltaic field, RMS current of a photovoltaic generator for grid‐connected systems. The RMS current is very useful for calculating energy losses in cables used in a PV generator. As well, a current factor has been defined in order to simplify RMS current calculation.

Identifying the exposure of taxonomic, functional, and phylogenetic diversity of steppe birds to renewable energy development

Conservation Biology, EarlyView.
Abstract Biodiversity is globally threatened by human impacts, including land‐use transformation and climate change, which has prompted a rapid transition from fossil fuels to cleaner energy sources, such as photovoltaic (PV) energy. However, utility‐scale PV plants require vast areas and can lead to conflicts with biodiversity conservation, making ...

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

Advanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential
