AI Article Synopsis
- A fresh HZSM-5 catalyst was modified using different voltages in a direct non-thermal plasma reactor to enhance its properties for biomass catalytic pyrolysis.
- The modification at 22 kV produced the best results, increasing the specific surface area, mesoporous volume, and total acid content by 17.02%.
- The catalyst modified at this voltage also exhibited the highest selectivity for monocyclic aromatic hydrocarbons at 40.55% during pyrolysis tests.
Article Abstract
Fresh HZSM-5 catalyst modification experiment was carried out on the direct non-thermal plasma (DNTP) reactor. The aim of this work was to study the effects of modified voltages on the physicochemical properties of HZSM-5 and its enhancement in biomass catalytic pyrolysis. The results showed that DNTP modification was performed at different voltages of 20 kV, 22 kV, 24 kV, compared with fresh HZSM-5, the effect of 22 kV voltage was preferably. H-22 had the largest specific surface area and mesoporous volume, and the total acid content added 17.02%. The biomass catalytic pyrolysis test was used to test the HZSM-5 catalytic activity after modification. The results showed that the catalyst obtained by the catalyst under 22 kV modified voltage had the highest monocyclic aromatic hydrocarbon selectivity of 40.55%.

The escalating challenges posed by water resource contamination, especially exacerbated by health concerns associated with microbial fungi threats, necessitate advanced disinfection technologies. Within this context, non-thermal plasma generated within bubble column reactors emerges as a promising antifungal strategy. The effects of direct plasma bubbles within different discharge modes and thus-produced plasma activated water (PAW) on the inactivation of Saccharomyces cerevisiae are investigated.

In most of the cases Interventional Radiology techniques and therapies are proposed for the management of symptomatic soft tissue benign tumors responsible for pain and/or compression symptoms aiming to offer a curative intent by means of tumor necrosis with subsequent symptoms' management and improvement of life quality. The ablative therapies include chemical, thermal and non-thermal approaches while, trans-arterial (chemo)embolization also has a distinct role. Adjunct ancillary techniques should be performed whenever necessary to increase efficacy and safety and avoid or reduce complications.

Clinical outcomes of catheter ablation remain suboptimal in patients with atrial fibrillation (AF), particularly in those with persistent AF, despite decades of research, clinical trials, and technological advancements. Recently, pulsed-field ablation (PFA), a promising non-thermal technology, has been introduced to improve procedural outcomes. Its unique feature of myocardial selectivity offers safety advantages by avoiding potential harm to vulnerable adjacent structures during AF ablation.

Background: Scientific literature, with no conflicts of interest, shows that even below the limits defined by the International Commission on Non-Ionizing Radiation Protection, microwaves from telecommunication technologies cause numerous health effects: neurological, oxidative stress, carcinogenicity, deoxyribonucleic acid and immune system damage, electro-hypersensitivity. The majority of these biological effects of non-thermal microwave radiation have been known since the 1970s.
Methods: Detailed scientific, political, and military documents were analyzed.
