“…Further, reported values of standard adsorption free energy ΔG°a ds of alkanes on silica surface show that ΔG°a ds decreases with an increase in alkane chain length in the range from −10 to −25 kJ/mol for hexane to nonane, Figure 4. 56,57 The above discussion explains the wettability condition of quartz substrate ahead of the wettability alteration of its surface by the dispensed nanofluids.…”

Advanced low-salinity aqueous formulations have shown promising results for rock wettability modification and interfacial tension reduction. Additives, such as surfactant and nanoparticles, can be used for such formulations. The interaction of these novel formulations with different fluid phases and the rock surface is, however, yet to be understood in detail. Thus, an experimental study was conducted in this study to investigate the interfacial tension and wettability of carbon dioxide and anionic surfactant (SDBS, 1.435 mM) at high pressure and temperature. The results show that the anionic surfactant (SDBS, 1.435 mM) augmented the effect of zirconia (ZrO 2 ) nanoparticles (100−2000 mg/L concentration) at low-salinity conditions and proved to be an effective wettability and interfacial tension modifier when used at appropriate divalent cation/sulfate ion ratios. Low-salinity surfactant nanofluids may thus be applied for wettability alteration and interfacial tension reduction for recovering residual oil, carbon dioxide-enhanced oil recovery, as well as carbon dioxide geosequestration. We also demonstrate in this study that the ratio of divalent cations to sulfate ions (0 ≤ M 2+ /SO 4 2− ≤ 4.427) has a significant role in interfacial tension reduction and wettability modification. We further show using contact angle wettability measurements that initial weak water− wet quartz surfaces can turn to more water−wet when zirconia nanoparticles used in the low-salinity formulation are in the range of 100−1000 mg/L. Interestingly, further incremental nanoparticle concentration decreases the water wettability but further reduces the carbon dioxide/brine interfacial tension.

“…The second ring in (+)-3-carene is the major structural feature setting it apart from the two pinenes, it has only three carbons and is positioned at one edge of the six-carbon ring, opposite the endocyclic double bond (Fig 2). Each structure effects the strength of intermolecular forces among their interacting molecules, and the force strengths are inversely related to each compounds vapor pressure [64,65] and associated liquid evaporation rate starting with the lowest for (+)-3-carene < (-)-β-pinene < (+)-α-pinene. Lures releasing them by direct evaporation require adjustments to provide similar release rates, such as using different numbers of containers, or modifying sizes of container openings, etc.…”

Red turpentine beetle, Dendroctonus valens (Coleoptera: Curculionidae: Scolytinae) is a non-aggressive pine bark beetle native to North America, and more aggressive invader in China. Dispersing pioneer beetles are attracted to potential host trees by oleoresin monoterpene kairomones, but respond more strongly to those combined with ethanol, a mixture often released from stressed, dying, or recently dead trees. (+)-3-Carene, usually the dominant or co-dominant monoterpene in ponderosa pine, Pinus ponderosa, is a stronger attractant than α-pinene or β-pinene where tested over a large portion of the D. valens range, while (+)-3-carene+ethanol was shown previously to attract twice the beetles of (+)-3-carene. A field test comparing D. valens attraction among the three monoterpenes when all are released with ethanol has never been reported, and was our objective. In three US Pacific Northwestern pine forests, (-)-β-pinene+ethanol lures attracted 1.4 to 1.9 times more beetles than (+)-3-carene+ethanol. (+)-or (±)-α-pinene+ethanol lures were least attractive. A 1:1:1 monoterpene mixture+ethanol lure attracted more beetles than the 1:1:1 lure, but it was not statistically higher. Monoterpenes were dispensed from low density polyethylene bottles and their release rates monitored in laboratory and field tests. Under laboratory conditions (+)-3-carene was released much more rapidly than (+)-α-pinene or (-)-β-pinene when dispensed separately, or in a 1:1:1 mixture. (+)-3-Carene in the 1:1:1 mixture increased the release of both pinenes over their rates when dispensed separately. (-)-β-Pinene+ethanol is currently the strongest kairomone lure for D. valens attraction in US northwest pine forests, and has value for beetle detection, monitoring, research, and management.

Organonitrates (ON) are important components of secondary organic aerosols (SOAs). α-Pinene (C 10 H 16 ), the most abundant monoterpene in the troposphere, is a precursor for the formation of several of these compounds. ON from α-pinene can be produced in the gas phase via photochemical processes and/or following reactions with oxidizers including hydroxyl radical and ozone. Gas-phase nitrogen oxides (NO 2 , NO 3 ) are N sources for ON formation. Although gas-phase reactions of α-pinene that yield ON are fairly well understood, little is known about their formation through heterogeneous and multiphase pathways. In the current study, surface reactions of α-pinene with nitrogen oxides on hematite (α-Fe 2 O 3 ) and kaolinite (SiO 2 Al 2 O 3 (OH) 4 ) surfaces, common components of mineral dust, have been investigated. α-Pinene oxidizes upon adsorption on kaolinite, forming pinonaldehyde, which then dimerizes on the surface. Furthermore, α-pinene is shown to react with adsorbed nitrate species on these mineral surfaces producing multiple ON and other oxidation products. Additionally, gas-phase oxidation products of α-pinene on mineral surfaces are shown to more strongly adsorb on the surface compared to α-pinene. Overall, this study reveals the complexity of reactions of prevalent organic compounds such as α-pinene with adsorbed nitrate and nitrogen dioxide, revealing new heterogeneous reaction pathways for SOA formation that is mineralogy specific.
