摘要：The nature of acidic and basic (alkaline) oxides can be easily illustrated via a series of three straightforward classroom demonstrations for high school and general chemistry courses. Properties of carbon dioxide, sulfur dioxide, and magnesium oxide are revealed inexpensively and safely. Additionally, the very different kinetics of hydration of SO2 (rapid) and CO2 (slow) are evident. The pH changes observed by use of universal indicator provide striking visual evidence that makes the concepts of acidic and basic oxides less abstract and more concrete than verbal or written descriptions alone. By using the MgO solution for the SO2 hydration reaction, one can mimic environmental interactions that lead to the neutralization of alkaline and acidic species. Interestingly, the SO2 and CO2 demonstrations can easily be adapted to environmental chemistry courses and especially the very relevant realm of climate change science. The difference in hydration rates explains why CO2 is a greenhouse gas, but SO2 is not listed as one. Variations of the CO2 hydration demonstration reveal the sensitivity of oceans to acidification by dissolved CO2 and the relationship of fossil fuel combustion to ocean acidification.

摘要：We report a poly(vinyl alcohol) (PVA)-coated porous graphitic carbon (PGC, Hypercarb) packing as a novel stationary phase for hydrophilic interaction liquid chromatography (HILIC). The exterior and the pores of the PGC particles are coated with a thin layer of PVA by soaking the particles in a PVA solution, filtering, and thermally cross-linking the PVA. Such PVA coated PGC particles (5.7 μm diameter), hereinafter called PVA–PGC are stable at least through pH 1.0–12.7, can be made in <2 h, and exhibit different selectivity relative to six commercial HILIC phases and bare PGC. To our knowledge, this is the first fully pH-stable, completely neutral HILIC phase. Excellent efficiency stable is observed for polar analytes (∼70 000 and 118 000 plates/m for cytosine and resorcinol, respectively). Retention closely resembles standard HILIC behavior. Other substances can also be easily incorporated in the PVA layer; an anion exchange column can be readily made by incorporating diallyldimethylammonium chloride in the PVA coating solution. The ease of preparation without the requirement of synthetic skills or paraphernalia and the possibility of incorporating a variety of modifiers makes this a particularly versatile approach.

摘要：We present an integrated model, SWITCH-China, of the Chinese power sector with which to analyze the economic and technological implications of a medium to long-term decarbonization scenario while accounting for very-short-term renewable variability. On the basis of the model and assumptions used, we find that the announced 2030 carbon peak can be achieved with a carbon price of ∼$40/tCO2. Current trends in renewable energy price reductions alone are insufficient to replace coal; however, an 80% carbon emission reduction by 2050 is achievable in the Intergovernmental Panel on Climate Change Target Scenario with an optimal electricity mix in 2050 including nuclear (14%), wind (23%), solar (27%), hydro (6%), gas (1%), coal (3%), and carbon capture and sequestration coal energy (26%). The co-benefits of carbon-price strategy would offset 22% to 42% of the increased electricity costs if the true cost of coal and the social cost of carbon are incorporated. In such a scenario, aggressive attention to research and both technological and financial innovation mechanisms are crucial to enabling the transition at a reasonable cost, along with strong carbon policies.

摘要：We report herein a crystal engineering strategy that affords a new and versatile metal–organic material (MOM) platform that is tunable in terms of both pore size and functionality. This platform is comprised of two long-known molecular building blocks (MBBs) that alternate to form a cationic square grid lattice. The MBBs, [Cu(AN)4]2 (AN = aromatic nitrogen donor), and [Cu2(CO2R)4] square paddlewheel moieties are connected by five different fs, L1–L5, that contain both AN and carboxylate moieties. The resulting square grid nets formed from alternating [Cu(AN)4]2 and [Cu2(CO2R)4] moieties are pillared at the axial sites of the [Cu(AN)4]2 MBBs with dianionic pillars to form neutral 3D 4,6-connected fsc (four, six type c) nets. Pore size control in this family of fsc nets was exerted by varying the length of the ligand, whereas pore chemistry was defined by the presence of unsaturated metal centers (UMCs) and either inorganic or organic pillars. 1,5-Naphthalenedisulfonate (NDS) anions pillar in an angular fashion to afford fsc-1-NDS, fsc-2-NDS, fsc-3-NDS, fsc-4-NDS, and fsc-5-NDS from L1-L5, respectively. Experimental CO2 sorption studies revealed higher isosteric heat of adsorption (Qst) for the smallest pore size material (fsc-1-NDS). Computational studies revealed that there is higher CO2 occupancy about the UMCs in fsc-1-NDS compared to other extended variants that were synthesized with NDS. SiF62– (SIFSIX) anions in fsc-2-SIFSIX form linear pillars that result in eclipsed [Cu2(CO2R)4] moieties at a distance of just 5.86 ?. The space between the [Cu2(CO2R)4] moieties affords a strong CO2 binding site that can be regarded as being an example of a single-molecule trap; this finding has been supported by modeling studies. Gas sorption studies on this new family of fsc nets reveal stronger affinity toward CO2 for fsc-2-SIFSIX vs fsc-2-NDS along with higher Qst and CO2/N2 selectivity. The fsc platform reported herein offers a plethora of possible porous structures that are amenable to tuning of both pore size and pore chemistry.

摘要：A life-cycle assessment (LCA) and cost analysis are presented comparing the environmental and economic impacts of using regenerative thermal oxidizer (RTO), granular activated carbon (GAC), and activated carbon fiber cloth (ACFC) systems to treat gaseous emissions from sheet-foam production. The ACFC system has the lowest operational energy consumption (i.e., 19.2, 8.7, and 3.4 TJ/year at a full-scale facility for RTO, GAC, and ACFC systems, respectively). The GAC system has the smallest environmental impacts across most impact categories for the use of electricity from select states in the United States that produce sheet foam. Monte Carlo simulations indicate the GAC and ACFC systems perform similarly (within one standard deviation) for seven of nine environmental impact categories considered and have lower impacts than the RTO for every category for the use of natural gas to produce electricity. The GAC and ACFC systems recover adequate isobutane to pay for themselves through chemical-consumption offsets, whereas the net present value of the RTO is $4.1 M (20 years, $0.001/m3 treated). The adsorption systems are more environmentally and economically competitive than the RTO due to recovered isobutane for the production process and are recommended for resource recovery from (and treatment of) sheet-foam-production exhaust gas. Research targets for these adsorption systems should focus on increasing adsorptive capacity and saturation of GAC systems and decreasing electricity and N2 consumption of ACFC systems.

摘要：Electrocatalytic conversion of carbon dioxide (CO2) into energy-rich fuels is considered to be the most efficient approach to achieve a carbon neutral cycle. Transition-metal dichalcogenides (TMDCs) have recently shown a very promising catalytic performance for CO2 reduction reaction in an ionic liquid electrolyte. Here, we report that the catalytic performance of molybdenum disulfide (MoS2), a member of TMDCs, can be significantly improved by using an appropriate dopant. Our electrochemical results indicate that 5% niobium (Nb)-doped vertically aligned MoS2 in ionic liquid exhibits 1 order of magnitude higher CO formation turnover frequency (TOF) than pristine MoS2 at an overpotential range of 50–150 mV. The TOF of this catalyst is also 2 orders of magnitude higher than that of Ag nanoparticles over the entire range of studied overpotentials (100–650 mV). Moreover, the in situ differential electrochemical mass spectrometry experiment shows the onset overpotential of 31 mV for this catalyst, which is the lowest onset potential for CO2 reduction reaction reported so far. Our density functional theory calculations reveal that low concentrations of Nb near the Mo edge atoms can enhance the TOF of CO formation by modifying the binding energies of intermediates to MoS2 edge atoms.

摘要：By invoking analogies to lime mortars of times past, this study examines the carbonation of portlandite (Ca(OH)2) by carbon dioxide (CO2) in the liquid and supercritical states as a potential route toward CO2-neutral cementation. Portlandite carbonation is noted to be rapid; e.g., >80% carbonation of Ca(OH)2 is achieved in 2 h upon contact with liquid CO2 at ambient temperatures, and it is only slightly sensitive to the effects of temperature, pressure, and the state of CO2 over the range of 6 MPa 鈮?p 鈮?10 MPa and 8 掳C 鈮?TView: ACS ActiveView PDF | PDF | PDF w/ Links | Full Text HTML Article Options ACS ActiveView PDF Hi-Res Print, Annotate, Reference QuickView PDF (4293 KB) PDF w/ Links (630 KB) Full Text HTML Abstract Figures References Add to ACS ChemWorx Sign in Retrieve Detailed Record of this Article Retrieve Substances Indexed for this Article Retrieve All References Cited for this Article Explore by: Author of this Article Any Author Research Topic Vance, Kirk Falzone, Gabriel Pignatelli, Isabella Bauchy, Mathieu Balonis, Magdalena Sant, Gaurav Search Last * First Middle Search Topic * Patents only search Search Tools & Sharing Add to Favorites Download Citation Email a Colleague Order Reprints Rights & Permissions Citation Alerts Share this Article History Published In Issue September 16, 2015 Article ASAP September 01, 2015 Just Accepted Manuscript August 26, 2015Received: June 28, 2015Accepted: August 26, 2015Revised: August 24, 2015 Close Loading...
