DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

open access: yesSmall, Volume 22, Issue 43, 3 August 2026.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Recent Strategies Toward Durable and Ion‐Tolerant Transition Metal‐Based Electrocatalysts in Seawater Electrolysis

open access: yesCarbon Energy, Volume 8, Issue 7, July 2026.
Recent strategies address these challenges through ion‐specific regulation, encompassing chloride‐tolerant and chloride‐regulating anodes together with cathode designs that suppress OH− accumulation and Mg2+/Ca2+ coupling. This ion‐management‐oriented framework provides general guidelines for achieving stable, selective, and scalable seawater ...

High‐Efficiency Phosphor Thin Films With Controlled Lateral Displacement for Low Color Crosstalk in Micro‐LED Displays

open access: yesJournal of the Society for Information Display, Volume 34, Issue 7, Page 626-636, July 2026.
High‐efficiency nano‐phosphor thin films were developed for micro‐LED color conversion, achieving high quantum efficiency and reduced lateral photon displacement. The optimized film structure effectively suppresses color crosstalk and enables high‐performance, full‐color micro‐LED displays.

Semiconductor nanoring lasers [PDF]

open access: yesApplied Physics Letters, 2011
Lasing in a subwavelength metal-clad nanoring resonator has been demonstrated with a tunable emission wavelength, controlled by the width of the ring. The emission wavelength is shown to be tunable within a 10 nm wavelength range by changing the ring width between 240 and 340 nm.

Lasing of nanoemitters with nanorings having Drude dispersion

open access: yesProgramación Matemática y Software
We systematically study the dynamics and laser emission of randomly distributed nanoemitters (NEs) integrated into two-dimensional (2D) array of metal nanorings (NR) enhanced by the plasmon-polariton (PP) excitations.

Toward Larger Cyclo‐9,10‐Anthryleneparaphenylenes

open access: yesChemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
During a macrocyclization with a dihydroanthracene diol as corner unit, larger oligomers than the trimer and tetramer were formed and isolated up to the nonamer. Their three‐dimensional structures were studied by X‐ray diffraction. The most abundant macrocycles were rearomatized to the corresponding CPP derivatives.

New Directions in Focused Ion Beam Induced Deposition for the Nanoprinting of Functional 3D Heterostructures

open access: yesAdvanced Materials Technologies, Volume 11, Issue 11, 5 June 2026.
Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...
