System for operating solid oxide fuel cell generator on diesel fuel [PDF]

open access: yes, 1997
A system is provided for operating a solid oxide fuel cell generator on diesel fuel. The system includes a hydrodesulfurizer which reduces the sulfur content of commercial and military grade diesel fuel to an acceptable level.

Thermal curing of an epoxy-anhydride system modified with hyperbranched poly(ethylene imine)s with different terminal groups [PDF]

open access: yes, 2017
New hyperbranched polymers (HBP) have been synthesized by reaction of a poly(ethylene imine) with phenyl and t-butyl isocyanates. These HBPs have been characterized by 1H-NMR (nuclear magnetic resonance of hydrogen) and Fourier transform infrared ...

Silicon as an intermediary between renewable energy and hydrogen [PDF]

open access: yes
Non-renewable energy sources are becoming depleted. Air and water (our environment) are precious and will be under increased jeopardy without effective energy and environmental policies.

Hydrogenation of Magnesium Nickel Boride for Reversible Hydrogen Storage [PDF]

open access: yes, 2010
We report that a ternary magnesium nickel boride (MgNi_(2.5)B_2) mixed with LiH and MgH_2 can be hydrogenated reversibly forming LiBH_4 and Mg_2NiH_4 at temperatures below 300 °C. The ternary boride was prepared by sintering a mechanically milled mixture

In situ formation of catalytically active graphene in ethylene photo-epoxidation. [PDF]

open access: yes, 2018
Ethylene epoxidation is used to produce 2 × 107 ton per year of ethylene oxide, a major feedstock for commodity chemicals and plastics. While high pressures and temperatures are required for the reaction, plasmonic photoexcitation of the Ag catalyst ...

Role of Additives in LiBH4-MgH2 Reactive Hydride Composite sorption reactions

open access: yes, 2010
The influence of additives on the reaction kinetics and microstructure refinement in LiBH4–MgH2 composites is investigated in detail. Indications of the rate-limiting processes during the reactions are obtained by comparison of the measured reaction kinetics with simulations with one specific rate-limiting process.

Investigation on different composition of powder metallurgy electrode (Cu-W) in high performance edm (HPEDM) on AISI D2 hardened steel [PDF]

open access: yes, 2013
The ideal selection of manufacturing conditions is one of the most important aspects to take into consideration in the majority of manufacturing processes and particularly in processes related to Electrical Discharge Machining (EDM).

Reactive hydride composites for efficient hydrogen energy storage

open access: yes, 2016
Solid state chemical storage of hydrogen in metals offers promising advantages over compressed hydrogen gas and condensed liquid hydrogen, especially for mobile applications with respect to safety and energy efficiency. However, no single metal hydride simultaneously satisfies the essential performance criteria for onboard hydrogen storage namely, high

Study of improved resins for advanced supersonic technology composites. Part 1: Heteroaromatic polymers containing ether groups. Part 2: Curing chemistry of aromatic polymers and composite studies [PDF]

open access: yes
Fourteen ether-containing, aromatic dianhydrides have been synthesized from N-phenyl-3 or 4-nitrophthalimide and various bisphenols. The process involves nucleophilic displacement of activated nitro groups with bisphenolate ions.

Molecular Mimics of Intermetallic Phases: Selective Alkylamide‐Ligand Deprotection Drives Co/Ga Cluster Formation

open access: yesAngewandte Chemie International Edition, EarlyView.
The bimetallic M14 cluster [Co3Ga2]H(μ2‐GaTMP)9 was achieved by a co‐reductive approach utilizing Mg and H2 to selectively deprotect and capture the Ga‐TMP metallo‐ligands, forming a Co/Ga alloyed cluster kernel, making it a structural representative of a related solid‐state counterpart.
