NUMERICAL MODELING OF COMBUSTION PROCESSES IN HYBRID ROCKET ENGINES
International Journal of Energetic Materials and Chemical Propulsion, 2016 Nowadays, numerical simulations of combustion processes in hybrid rockets are generally considered as a qualitative tool used mainly to describe the flow field inside the rocket engine. A research effort is of major importance in order to change this trend.

Towards an integrated molecular understanding of plant hormones
Journal of Integrative Plant Biology, EarlyView.This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Narrative reconstruction of the self: Living funerals as rituals of trauma and transformation
The Australian Journal of Anthropology, EarlyView.Abstract Living funerals mark a radical reconfiguration of contemporary engagements with mortality, transforming death from an imposed ending into an actively authored narrative. This study examines the practice in Hong Kong's hybrid sociocultural landscape, where traditional Chinese death rituals collide with neoliberal selfhood and globalised ...

Radiation analysis of various vehicle and payload configurations for the reusable nuclear shuttle [PDF]
, 1972 Radiation analyses were performed and shielding weight requirements were estimated for various candidate vehicle and payload configurations for use with the reusable nuclear shuttle. The analyses included both point kernel and Monte Carlo approaches. The

Situating African FinTech in Global Financial Networks
Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.Short Abstract This paper explores the geographical patterns of firm creation and investments in African FinTech and how they have evolved since the emergence of FinTech on the continent. Our findings show waves of investment, specialisation of different FinTech centres and the networks of FinTech capital.

Impact of radiation dose on nuclear shuttle configuration [PDF]
, 1972 The impact of nuclear radiation (from the NERVA propulsion system) on the selection of a reference configuration for each of two classes of the reusable nuclear shuttle is considered.

Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media
Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.

Carbon Neutralization, Volume 5, Issue 3, May 2026.An electron structure modulation engineering strategy is developed by tuning the first coordination shell and leveraging synergistic effects with adjacent nanoparticles of Co single atoms. The CoS@Co–N2S2 catalyst achieves an average H2O2 selectivity of 88% (0.3–0.55 V), whereas CoS2@Co–NS3 exhibits 52% 4e− selectivity.
