Combining Cover Crops and No‐Tillage Enables Reduced Herbicide Inputs in Safflower (Carthamus tinctorius L.) Crop

open access: yesInternational Journal of Agronomy, Volume 2026, Issue 1, 2026.
The increasing need to reduce reliance on chemical inputs in agriculture highlights the importance of integrated weed management strategies. Two‐year field experiment was conducted to evaluate the effects of cover crops, tillage systems, and reduced pre‐emergence herbicide rates on weed management and safflower (Carthamus tinctorius L.) performance ...

3D Conjugated Nonflat Biphenyl Side Chains: Their Exclusive Role in Inducing Negative Electrostatic Potential in Efficient Organic Solar Cells

open access: yesSmall, Volume 21, Issue 41, October 16, 2025.
A nonfullerene acceptor named BPY, featuring 3D biphenyl side chains, is developed to reduce nonradiative energy loss in organic solar cells. The improved dipole moments, negatively charged surface electrostatic potential, and proper morphology of BPY enhance charge dynamics and reduce nonradiative recombination, enabling high‐performance OSCs with PM6:

The Effect of Regioisomerism on the TADF Properties of Organic Dyes

open access: yesChemistryEurope, Volume 3, Issue 5, September 18, 2025.
The properties of TADF emitters are highly dependent on the chosen electron donor and acceptor, as well as the π‐system that links them together. Herein, we show that regioisomerism affects the physical properties of spirobifluorene‐based systems in solution, thin films and crystals.
