Abstract: With the strengthened awareness of environmental protection and the growing interests of wastes recycling, silicon recovery from polycrystalline silicon kerf loss (PSKL) has drawn extensive attentions all over the world. In this paper, an efficient and...
Biogenic silica accumulation in picoeukaryotes: Novel players in the marine silica cycle.
Publication Type: Academic Journal
Source(s): Environmental microbiology reports [Environ Microbiol Rep] 2023 Aug; Vol. 15 (4), pp. 282-290. Date of Electronic Publication: 2023 Mar 29.
Abstract: It is well known that the biological control of oceanic silica cycling is dominated by diatoms, with sponges and radiolarians playing additional roles. Recent studies have revealed that some smaller marine organisms (e.g. the picocyanobacterium Synecho...
Controlling the surface silanol density in capillary columns and planar silicon via the self-limiting, gas-phase deposition of tris(dimethylamino)methylsilane, and quantification of surface silanols after silanization by low energy ion scattering.

Abstract: Surface silanols (Si-OH) play a vital role on fused silica surfaces in chromatography. Here, we used an atmospheric-pressure, gas-phase reactor to modify the inner surface of a gas chromatography, fused silica capillary column (0.53 mm ID) with a small...
An improved digestion and analysis procedure for silicon in plant tissue.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Sep 08; Vol. 18 (9), pp. e0289151. Date of Electronic Publication: 2023 Sep 08 (Print Publication: 2023).
Abstract: Silicon (Si) in plant tissues reduces abiotic and biotic stress, but it is incorporated as silica (SiO2), which is difficult to solubilize for analysis. We modified an oven-induced tissue-digestion and analysis method to improve Si solubilization and v...
Synthesis of ordered mesoporous silica from biomass ash and its application in CO 2 adsorption.
Publication Type: Academic Journal
Source(s): Environmental research [Environ Res] 2023 Aug 15; Vol. 231 (Pt 1), pp. 116070. Date of Electronic Publication: 2023 May 05.
Abstract: It is possible to achieve high-value utilization of solid wastes and lower the cost of mesoporous silica synthesis by synthesizing mesoporous silica from solid wastes. In this study, silica was extracted using the alkali fusion method using biomass ash...
Cation-dependent assembly of hexagonal DNA origami lattices on SiO 2 surfaces.
Publication Type: Academic Journal
Source(s): Nanoscale [Nanoscale] 2023 Aug 10; Vol. 15 (31), pp. 12894-12906. Date of Electronic Publication: 2023 Aug 10.
Abstract: DNA origami nanostructures have emerged as functional materials for applications in various areas of science and technology. In particular, the transfer of the DNA origami shape into inorganic materials using established silicon lithography methods hol...
Silica deposition in plants: scaffolding the mineralization.
Publication Type: Academic Journal
Source(s): Annals of botany [Ann Bot] 2023 Jul 10; Vol. 131 (6), pp. 897-908.
Abstract: Background: Silicon and aluminium oxides make the bulk of agricultural soils. Plants absorb dissolved silicon as silicic acid into their bodies through their roots. The silicic acid moves with transpiration to target tissues in the plant body, where it...
Hydroxyl ion absorption in on-chip high-Q resonators.
