Qualitative Real‐Time Disinfection Monitoring through Lipid Nanoparticle‐Separated Fluorophore‐Quencher Pairs

open access: yesAdvanced Sensor Research, EarlyView.
A real‐time method for monitoring surface disinfection is presented using fluorescence‐labeled DNA and lipid nanoparticles. The system detects chemical disintegration caused by disinfectants, producing an immediate fluorescence change visible with simple tools.

Evaluating Bicarbonate Electrolyzer Configurations for Energy‐Efficient Formate Production

open access: yesAdvanced Sustainable Systems, EarlyView.
Reactive carbon capture (RCC) with bicarbonate electrolyzers (BEs) offers an efficient alternative to gas‐fed CO2 electrolyzers by eliminating regeneration and pressurization steps. This study optimizes BE configurations and compares RCC chains to gas‐fed carbon chains for formate production.

Polyethyleneimine‐Modified Biosorbent Based on Banana Pseudostem Biomass for Environmental Remediation and Food Analysis

open access: yesAdvanced Sustainable Systems, EarlyView.
Biosorbents derived from banana pseudostem are functionalized with polyethyleneimine, with or without glutaraldehyde, and evaluated for dye removal and solid‐phase extraction. The materials exhibit high adsorption capacities and broad pH applicability in dye removal, while computational studies reveal amino groups as key interaction sites.

Ni Single Atoms in Zeolite Beta for Selective Alkyne Hydrogenation

open access: yesAdvanced Sustainable Systems, EarlyView.
Single‐atom Ni in zeolite Beta (Ni1/BEA) selectively remove trace acetylene from ethylene. Ni1/BEA achieve full conversion with ≈89% ethylene selectivity, stable for 24 h without coking, and 12 times higher TOF than prior zeolite‐supported single‐atom Ni catalysts. Na+ exchange suppress Brønsted acid‐catalyzed oligomerization. Under ethylene‐rich feeds,
