Advanced Functional Materials, EarlyView.The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Minimal NOx emission by Lysinibacillus sphaericus in nutrient poor soil
Soil & Environment, 2018 The aim of this study was to determine whether nitrogen dioxide emissions by Lysinibacillus sphaericus exist in nutrient poor soil. First, we evaluated the presence of two genes involved in denitrification (nosF and nosD) by PCR screening of five ...

Analysis of available technologies for the separating nitrogen and carbon dioxide from natural gas [PDF]
Tehnika, 2018 In the Serbia there are more gas reservoirs with reserves of more than 10 million Sm3 of natural gas. One of the reasons why they have not been exploited yet is that they contain nitrogen and carbon dioxide, that should be separated during the production

Advanced Functional Materials, EarlyView.A cerium oxide‐carbon nanohybrid catalyst is synthesized via two distinct routes and is integrated into H‐type cells and gas diffusion layers (GDLs) to enhance electrochemical performance. Structural variations significantly affect performance, with the solvothermal sample exhibiting higher current densities.

Advanced Functional Materials, EarlyView.This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.
