“…1). It should be pointed out that the adsorption of Cys was studied only on bare and octadecyl silica (Basiuk and Gromovoy 1996;Basiuk 2002) and silica gel/poly A (Mellersh and Wilkinson 2000). A review published by Lahav and Chang (1976) and various other papers mentioned in the introduction show the results of adsorption for several amino acids on clays/minerals/ sediments.…”

“…Numerous papers about the adsorption of amino acids on minerals/clays/sediments have been published such as: Ala/Gly/Ser/Phe/His on β-FeOOH.Cl n (Holm et al 1983); several amino acids on clays (Paecht-Horowitz 1978;Aufdenkampe et al 2001;Ding and Henrichs 2002); Lys/Leu/Asp on titanium dioxide (Rogacheva and Bobyrenko 1985); amino acids on hydroxyapatite/calcite/albite (Tanaka et al 1989;Churchill et al 2004); Gly/Lys/Glu on hematite (Ben-Taleb et al 1994); Gly/Ser/Cys on pyrite (Bebié and Schoonen 2000); pool of 20 protein amino acids on silica gel/poly A (Mellersh and Wilkinson 2000); various amino acids on several river or marine sediments (Henrichs and Sugai 1993;Aufdenkampe et al 2001; Montluçon and Lee 2001;Ding and Henrichs 2002) and several amino acids on silica/sand/quartz (Basiuk and Gromovoy 1996;Basiuk 2002;Zaia et al 2002;Churchill et al 2004). In general, all these papers showed that amino acids with positively or negatively charged R groups were adsorbed more than other amino acids.…”

In the present paper, the adsorption of amino acids (Ala, Met, Gln, Cys, Asp, Lys, His) on clays (bentonite, kaolinite) was studied at different pH (3.00, 6.00, 8.00). The amino acids were dissolved in seawater, which contains the major elements. There were two main findings in this study. First, amino acids with a charged R group (Asp, Lys, His) and Cys were adsorbed on clays more than Ala, Met and Gln (uncharged R groups). However, 74% of the amino acids in the proteins of modern organisms have uncharged R groups. These results raise some questions about the role of minerals in providing a prebiotic concentration mechanism for amino acids. Several mechanisms are also discussed that could produce peptide with a greater proportion of amino acids with uncharged R groups. Second, Cys could play an important role in prebiotic chemistry besides participating in the structure of peptides/proteins. The FT-IR spectra showed that the adsorption of amino acids on the clays occurs through the amine group. However, the Cys/clay interaction occurs through the sulfhydryl and amine groups. X-ray diffractometry showed that pH affects the bentonite interlayer, and at pH 3.00 the expansion of Cys/bentonite was greater than that of the samples of ethylene glycol/bentonite saturated with Mg. The Mössbauer spectrum for the sample with absorbed Cys showed a large increase ( approximately 20%) in ferrous ions. This means that Cys was able to partially reduce iron present in bentonite. This result is similar to that which occurs with aconitase where the ferric ions are reduced to Fe 2.5.

“…Alternatively, as we shall see in the following paragraph, polymerization could occur during a later drying step rather than immediately after adsorption; in that case, there is no need for adsorbed polymers to be highly stabilized energetically relative to polymers in solution, and therefore desorption of biopolymers need not be so unfavorable. In fact, there are not very many precise data on the thermodynamics of amino acids and peptide adsorption, with the notable exception of adsorption on silica where many free energies of adsorption were estimated by Basiuk (Basiuk and Gromovoy 1996;Basiuk 1998). For monomers, they are almost always positive (0 to + 4 kJ mol −1 ).…”

The present paper offers a review of recent (post-1980) work on amino acid adsorption and thermal reactivity on oxide and sulfide minerals. This review is performed in the general frame of evaluating Bernal's hypothesis of prebiotic polymerization in the adsorbed state, but written from a surface scientist's point of view. After a general discussion of the thermodynamics of the problem and exactly what effects surfaces should have to make adsorbed-state polymerization a viable scenario, we examine some practical difficulties in experimental design and their bearing on the conclusions that can be drawn from extant works, including the relevance of the various available characterization techniques. We then present the state of the art concerning the mechanisms of the interactions of amino acids with mineral surfaces, including results from prebiotic chemistry-oriented studies, but also from several different fields of application, and discuss the likely consequences for adsorption selectivities. Finally, we briefly summarize the data concerning thermally activated amide bond formation of adsorbed amino acids without activating agents. The reality of the phenomenon is established beyond any doubt, but our understanding of its mechanism and therefore of its prebiotic potential is very fragmentary. The review concludes with a discussion of future work needed to fill the most conspicuous gaps in our knowledge of amino acids/mineral surfaces systems and their reactivity.

“…The adsorption of pyridnium ion is driven by either electrostatic interaction of the positively charged pyridinium ion with the fewer negatively charged silanolates or by hydrogen bonding between the protonated amino group (≡N + -H δ+ ) of the pyridinium ion, a hydrogen bond donor, and the predominant silanol groups, 13 hydrogen bond acceptors, on the silica surface. Several authors [12][13][14][15][16][17][18][19] suggested that the lone pair of electrons from the electronegative oxygen atom of the silanol (≡SiO δ− H δ+ ) group has only a weak attraction toward hydrogen bond donors, for example the protonated amine groups in our case. Hence, the resulting hydrogen bonding is weak and the electrostatic adsorption of the charged pyridinium ion is more likely the cause of the observed reduction in oxide RR.…”

Following our earlier analysis of amino acids, we investigated the effectiveness of acetic acid, pyridine, and sorbitol that were chosen to represent carboxylic acid, amine and alcohol functional group families, respectively, as additives in ceria dispersions for polishing SiO 2 and Si 3 N 4 films. By comparing the speciation of the additives available and the material removal rates with respect to pH, we identified that the removal rates of nitride, but not oxide, are suppressed to <1 nm/min in the pH range where the additive species containing a protonated amino group or a neutral carboxylic group or a neutral hydroxyl group are dominant. All of these species are strong hydrogen bond donors and can form strong hydrogen bonds with Si 3 N 4 surface while their corresponding bonding on SiO 2 surface sites is weaker. The stronger hydrogen bonding hinders Si 3 N 4 hydrolysis and suppresses Si 3 N 4 removal. In contrast, the weakly bound additive species are easily removed from the SiO 2 surface by the polishing pad and the ceria abrasives, leading to high SiO 2 to Si 3 N 4 removal rate selectivity. Similar results were also obtained with valeric acid, imidazole, glucose, sucrose, and mannitol, confirming the importance of a strong hydrogen bond formation in a broader class of additives. Shallow trench isolation (STI), which helps isolate the transistors and prevents shorting and cross-talk, is a widely used process in semiconductor device fabrication. The STI process includes the deposition of silicon nitride on a thermally grown pad oxide followed by the etching of a shallow trench into the silicon substrate. A layer of silicon oxide such as tetraethyl ortho silicate (TEOS) oxide, high density plasma (HDP) oxide, or high aspect ratio process (HARP) oxide is deposited on the entire substrate surface, not only filling the trenches but also creating an uneven topography. After the trenches are filled, the excess deposited oxide needs to be removed and the topography planarized before the fabrication of any IC elements. So far, chemical mechanical polishing/planarization (CMP) has been the only viable technique to remove the overburden oxide and planarize the topographies. This STI CMP step requires a slurry which polishes the overburden oxide with high oxide removal rate (RR) and stops on the underlying nitride surface with minimal nitride loss and oxide dishing.Ceria-based dispersions 1 containing various additives have a huge market position for planarizing these STI structures efficiently because of their superior ability to polish oxide films at high rates using only a low solids loading of ∼1 wt% or less and to stop on the underlying nitride film with minimal loss as well as dishing. 2,3 In the absence of any additive, these same ceria slurries would also produce significant nitride RRs and lead to considerable nitride loss. Hence, many types of additives (amino acids, amines, surfactants, polymers and acids) were investigated to achieve high oxide-to-nitride rate selectivity. 4-12For example, America and Babu ...
