Systematic investigation on polymer layer selection for flexible thin film encapsulation

Lifetime engineering of bioelectronic implants with mechanically reliable thin film encapsulations

“…Yang et al, though not intending to study ALI, coincidentally demonstrated this effect in their investigation on the effect of polymer layer selection for flexible thin film encapsulation. They found that as polymer surface energy decreased, the penetration depth of the ALD alumina layer correspondingly increased, resulting in lower surface stress of the alumina layer and increased flexibility of the overall film [287]. Furthermore, ALI has even shown the potential to impart self-healing capabilities to inorganic barrier layers via migration of inorganic nanoparticles within the polymer matrix after damage [288].…”

Acceptor–donor–acceptor based thermally activated delayed fluorescent materials: structure–property insights and electroluminescence performances

“…Organic light-emitting diode (OLED) technology has been extensively applied in high-end solid-state lighting and flatpanel displays due to its superior advantages of low driving voltage, flexibility, fast response, and wide viewing angle. [1][2][3][4][5] According to the spin-statistics rules, electro generated excitons have a ratio of 1 : 3 with 25% singlet and 75% triplet excitons. Conventional fluorescent materials (first generation) with high photoluminescence quantum yields (PLQYs) can only utilize singlet excitons, while the energies of triplet excitons have deviated via nonradiative transition processes.…”

Cobalt–benzimidazole swapped metal–organic macrocycle with reduced graphene oxide as a hybrid electrocatalyst for highly efficient oxygen evolution reaction

“…Among the various energy-conversion technologies, splitting water into hydrogen (H 2 ) and oxygen (O 2 ) by electrochemical techniques is considered a green and renewable innovation to meet the enormous energy demand in the forthcoming years with several applications. 3–6 However, the electrolysis of water to O 2 and H 2 through oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is a more complicated process as it requires a high overpotential. 7–9 Subsequently, noble materials, such as Ru, Ir, and Pt, are considered efficient catalysts for water splitting due to their lower operating potential, high electrical conductivity, and good chemical stability.…”
