Graphene‐Based Wearable Textile Triboelectric Nanogenerators and Biomechanical Sensors

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a wearable textile‐based triboelectric nanogenerator (T‐TENG) using sprayed graphene enhanced with a PVA adhesion layer. The graphene‐based electrode demonstrates high electrical conductivity and robustness to multiple bends. The fabricated T‐TENG provides stable and efficient output, with strong responsiveness to biomotion.

Probing color coherence effects in pp collisions at [Formula: see text]. [PDF]

open access: yes, 2014
A study of color coherence effects in pp collisions at a center-of-mass energy of 7[Formula: see text] is presented. The data used in the analysis were collected in 2010 with the CMS detector at the LHC and correspond to an integrated luminosity of 36 ...

Linking Device Performance to Nanoscale Photoactivation of Grain Boundaries in 2D Hybrid Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.

Structural Modulation of Charge Transfer in Donor–Acceptor Systems: Effects of Donor Type and Connectivity

open access: yesAdvanced Optical Materials, EarlyView.
A coherent phthalimide acceptor platform with planar (Cz—carbazole) and spiro‐type (SAF—spiroacridine fluorene) donors enables systematic tuning of donor geometry and coupling, driving the evolution of excited‐state topology from classical CT‐TADF and fluorescence/RTP to CT‐driven and LE‐assisted TADF with OLED efficiencies ≈ 36%.
