Advancement in Design of HHO Generator

open access: yes
The usage of fossil gases(like LPG) and the resulting drastic increase in pollution levels has made us realize the need for additional sustainable gas which does not cause pollution. This research ended in an innovative concept of utilizing Brown gas (also known as HHO gas) as a fuel enhancer for LPG gas cylinders employed in cooking activities ...

Identification of symbiotic nitrogen fixation‐modulating factors in alfalfa and mechanism elucidation of MsHHO3

open access: yesThe Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Symbiotic nitrogen fixation (SNF), a unique nitrogen acquisition mechanism formed through the interaction between leguminous plants and rhizobia, plays a critical role in reducing dependence on chemical fertilizers. However, in alfalfa (Medicago sativa L.), the mechanisms underlying nitrate‐responsive SNF remain poorly understood. In this study,

Unraveling Temporal Fish Diversity in a Neotropical Hydropower Reservoir: Comparing eDNA Metabarcoding to Traditional Fishing Methods

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Comparing eDNA metabarcoding and gillnet surveys in a Neotropical reservoir, this study finds that eDNA detects greater species richness yet reveals distinct assemblage structures. The results underscore the value of integrating both methods to achieve comprehensive biodiversity monitoring in hydropower‐impacted ecosystems.
