The phrase "as a solid source" is correct and usable in written English.
It can be used when referring to something that is reliable or trustworthy, often in the context of information or evidence.
Example: "The research paper was cited multiple times in the article, establishing it as a solid source for the claims made."
Alternatives: "as a reliable source" or "as a trustworthy source."
In his mind, publishing the names and mugshots of everyone arrested in the past 30 days is a solid source of entertainment, as well as a public service.
Chemoheterotrophic denitrification technologies using woodchips as a solid carbon source (i.e., woodchip bioreactors) have been widely trialed for treatment of diffuse-source agricultural nitrogen pollution.
A method is reported for the growth of multiwall carbon nanotubes (MWCNTs) using polyacrylonitrile as a solid carbon source and nanosized SiO2 particles as catalyst.
Also demonstrated by Shen et al. (2013), the application of starch/polylactic acid as a solid carbon source undermined the denitrification rate due to the conspicuous difference of biodegradability between the two carbon-blended components.
In detail, the boron nitride crucible holding GaAs powders (~1 g, 99.9999 % purity) and the SiO2/Si substrates (50-nm-thick thermal oxide) with the thermally deposited Au film (2.5 nm in nominal thickness) are placed in the centers of the upstream and downstream zones of a two-zone tube furnace, respectively, serving as the solid source and the growth catalyst.
The bio-char was a porous carbonaceous material with high energy content, which can be applied as a solid fuel, adsorbent or source of biofertilizer.
In addition to lower power consumption, the AQUOS LED series is built to last longer – as a solid-state light source, LEDs generate less heat and are more durable, leading to a longer lifespan – an expected 100,000 hours, two thirds longer than traditional LCD TVs.
The goal of this research is to propose the use of industrial by-products as solid sources of silica in replacement of commercial sodium silicate (SS) for the manufacture of geopolymeric binary binders.
Digi Times, which is about as solid as source as you can get, says mass production will begin in May.
Our MBE system (VG-V80H) was equipped with solid sources of Al, Ga, As, P, and two sources of In(1,2).
