Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells
Advanced Functional Materials, EarlyView.Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

Proceedings of the American Mathematical Society, 1971 Fell has proved that the process of inducing representations of a locally compact group from representations of closed subgroups is a continuous process if topologies are defined on the spaces of representations in the right way. As a corollary he shows that inducing preserves weak containment.

Industrial round-wood losses associated with motor-manual tree felling and bucking (Case study: Kheyrud forest, Iran) [PDF]
Iranian Journal of Wood and Paper Industries, 2015 Damage to the harvested log can occur during the felling, delimbing, bucking, skidding, piling, and hauling functions of wood harvesting. A field-based study was performed to determine the amount of industrial round-wood losses associated with most ...

Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces
Advanced Functional Materials, EarlyView.A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures
