Identification and Structural Analysis of New Nrf2 Activators by Mechanism‐Based Chemical Transformation of 15‐Deoxy‐Δ12, 14‐PGJ2

Mechanism‐based chemical transformation of 15‐deoxy‐Δ^{12, 14}‐PGJ₂ (15d‐PGJ₂) resulted in a series of new NF‐E2‐related factor‐2 (Nrf2) activators and detailed elucidation of the function of each electrophilic binding site. In addition, HO‐1 expression resulting from Nrf2 activation through enhanced dissociation of the Keap1–Nrf2 complex by the new activators was proved.     

Preparation of graphene/multi-walled carbon nanotube hybrid and its use as photoanodes of dye-sensitized solar cells

This study employed a solution-based method to prepare a 3-D hybrid material comprising graphene and acid-treated multi-walled carbon nanotubes (MWCNTs). The adsorption of MWCNTs on graphene reduces the π–π interaction between graphene sheets resulting from steric hindrance, providing a subsequent reduction in aggregation. Optimal proportions of MWCNTs to graphene (2:1) enabled the even distribution of individual MWCNTs deposited on the surface of the graphene. The hybrid 3-D material was incorporated within a TiO₂ matrix and used as a working electrode in dye-sensitized solar cells (DSSCs). The hybrid material provides a number of advantages over electrodes formed of either MWCNTs or graphene alone, including a greater degree of dye adsorption and lower levels of charge recombination. In this study, DSSCs incorporating 3-D structured hybrid materials demonstrated a conversion efficiency of 6.11%, which is 31% higher than that of conventional TiO₂-based devices.     

Prevention of the development of polluting characteristics in cooking water residue from nixtamalisation of corn by removing solid lime particles

Removing solid lime particles (SLP) may help to prevent polluting characteristics of corn cooking wastewater (nejayote). The objective of this study was to evaluate the polluting characteristics of nejayote and characteristics of nixtamal, masa and tortilla using SLP-free solutions (SLPF) for the nixtamalisation process. Two SLPF treatments: calcium hydroxide (CHYDROX) and calcium oxide (COXIDE) were compared against traditional nixtamalisation (TRADNIX). Polluting characteristics including pH, settleable solids, total hardness, alkalinity and chemical oxygen demand (COD) reduced by 29.5% and 24.3%, 61.9% and 63.3%, 46.3% and 54.7%, 43.3% and 55.1%, 41.1% and 67.7% in CHYDROX and COXIDE, respectively, compared to TRADNIX. Masas and tortillas from SLPF treatments were whiter than those from TRADNIX. Moisture in SLPF tortillas was lower by 4.3–6.3% compared to TRADNIX. Tortillas from SLPF treatments had higher maximum tensile strength (0.04–0.08 N mm⁻²) than TRADNIX. Removing SLP is a viable strategy for preventing pollution from the nixtamalisation process.     

Effect of row space and irrigation on seed composition of Turkish sesame (Sesamum indicum L.)

The effect of row space (RS) and irrigation (IR) on total protein, total oil, and fatty acid composition of Harran-grown sesame seed was studied. Total oil content of sesame varied from 46.4 to 51.5%. The oil and protein contents were significantly different among treatments (P<0.01) in 1998 and 1999. IR affected oil content significantly (P<0.01) in both years, and RS had no significant effect. The protein content was significantly influenced by RS and IR at P<0.05 and P<0.01, respectively. RS 70 cm had the highest protein content followed by RS 60, 50, and 40 cm, respectively. IR every 24th day resulted in the highest level of protein, followed by 18th-, 12th-, and 6th-day irrigation, respectively. Correlation coefficients between protein and oil content were −0.34 in 1998 and −0.59 in 1999. RS (P<0.05) and IR (P<0.01) influenced oleic and linoleic acid contents significantly. Interactions of RS and IR were also found to be significant (P<0.05) over the oleic and linoleic acid levels.     

Internalizing externalities of electricity generation: An analysis with MESSAGE-MACRO

This paper examines the global impacts of a policy that internalizes the external costs (related to air pollution damage, excluding climate costs) of electricity generation using a combined energy systems and macroeconomic model. Starting point are estimates of the monetary damage costs for SO₂, NO_X, and PM per kWh electricity generated, taking into account the fuel type, sulfur content, removal technology, generation efficiency, and population density. Internalizing these externalities implies that clean and advanced technologies increase their share in global electricity production. Particularly, advanced coal power plants, natural gas combined cycles, natural gas fuel cells, wind and biomass technologies gain significant market shares at the expense of traditional coal- and gas-fired plants. Global carbon dioxide emissions are lowered by 3% to 5%. Sulfur dioxide emissions drop significantly below the already low level. The policy increases the costs of electricity production by 0.2 (in 2050) to 1.2 € cent/kWh (in 2010). Gross domestic product losses are between 0.6% and 1.1%. They are comparatively high during the initial phase of the policy, pointing to the need for a gradual phasing of the policy.
