Micro‐ and Macrostructure Effects on Hydrogen Release Using 3D‐Printed Reactor‐Catalysts
Not by its cover: We show here that the internal structure of a hydrogen generation reactor can govern the rates of reaction through a combination of efficient mass transfer and pore access, which can be optimized using metal 3D printing. ABSTRACT We report the design, fabrication, and testing of 3D‐printed Al–stainless steel reactor‐catalyst monoliths

Survey study of the efficiency and economics of hydrogen liquefaction
The production of liquid hydrogen, with coal as the starting material, is reported. The minimum practicable energy and cost for liquefaction of gaseous hydrogen in the 1985-2000 time period is presented to investigate the possible benefits of the ...

Thermoacoustic Modeling of Cryogenic Hydrogen
Future thermoacoustic cryocoolers employing hydrogen as a working fluid can reduce reliance on helium and improve hydrogen liquefaction processes. Traditional thermoacoustic modeling methods often assume ideal-gas thermophysical properties and neglect ...

Sedimentation‐driven environmental filtering shapes community assembly of cryptic coralline algae
Abstract Community assembly of cryptic crustose coralline algae (CCA) underlies the formation of algal reefs across the global ocean, yet the ecological mechanisms shaping these communities remain poorly understood. Sedimentation has been linked to variation in CCA community structure across the Taoyuan Algal Reef (TAR), the world's largest subtropical

Enhancing Hydrogen Storage in Carbon‐Substituted Beryllium Nitride: A DFT‐Based Investigation
Carbon‐substituted BeN4 monolayers enable efficient hydrogen storage, achieving 6.02 wt% uptake with moderate adsorption energy (−0.24 eV) and near‐ambient desorption temperature (308 K). These results highlight BeN4 as a promising candidate for practical hydrogen storage applications.

In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...

Guidelines for the preparation of hydrogels with protective function
Abstract As three dimensional network structure functional materials, protective hydrogels, with their excellent biocompatibility, high water content, and the ability to provide physical barriers and regulate the environment for active substances/cells, have shown broad prospects in fields such as drug delivery, tissue engineering, and food ...
