Techno‐economic and environmental assessment of a hybrid renewable energy system for a date molasses factory in Iraq using HOMER Pro

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Iraq currently faces a significant electricity deficit estimated at approximately 18 000 MW, resulting in frequent and sometimes prolonged power outages that disrupt both economic activities and social life. The widening gap between energy supply and demand, combined with environmental concerns associated with fossil fuel consumption ...

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...

Reversible Phase‐Change‐Induced Transparency Switching and Dynamic Thermal Regulation Gel for Energy‐Efficient Smart Windows

open access: yesEcoEnergy, EarlyView.
The phase transition process imparts shape‐stable gels with the capability of reversible transparency modulation and temperature‐responsive heat storage and release. When applied to smart windows, this property ensures the maintenance of thermal energy within the human thermal comfort zone, thereby facilitating indoor energy conservation.

No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

Co‐Firing Slow Solidification Process for Growing Indium‐Doped Cs3Cu2I5 Single Crystals With Record‐Breaking X‐Ray Detection Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.
