The article will be focused on methods of chemical modification of NR and the use of improved traditional fillers such as carbon black (CB) and silica. Modification reactions include epoxidation, hydrogenation, and grafting vinyl monomers onto NR molecules. Some methods of surface modification of NR film were also reviewed. Thanks to modification the NR degree of unsaturatiton is decrease that leads to its enhanced aging resistance.

Self-driven ultraviolet photodetectors based on wide-bandgap semiconductors have been well investigated but are still being explored for further performance enhancement. Here we report a self-driven electrochemical ultraviolet photodetector (EUVPD) using a three-dimensional nanostructured photoanode based on defect-engineered TiO2 nanotube arrays (TNAs) modified with single-walled carbon nanotubes (SWCNTs) to enhance photoelectric performance.

Anion exchange membrane fuel cells (AEMFCs) have recently received significant attention due to their potential to use non-Pt catalysts. In this work, we developed bimetallic PdNi nanoparticles supported on Vulcan XC72R carbon black (PdNi/C) using a wet impregnation method applied to AEMFC anode electrodes.

A glassy carbon electrode, modified with gold nanoparticles/over-oxidized poly-eriochrome black T film, was fabricated for sensitive determination of As(III) by stripping voltammetry in an acidic medium. The electrode surface properties were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS).

The improvement of thermal protection properties of materials to diversify the thermal protection material family is a growing trend. Accordingly, this paper focuses on determining the influence of the percentage of carbon nano powder (0-14%) on the thermal, physical and mechanical properties of carbon fiber/phenolic matrix composite (CPC) in order to find out the extent of reasonable proportion of carbon powder to improve thermal protection.

In this study, a portable instrument, microAethe® model AE51, was used to continuously measure BC concentrations in various microenvironments within buildings and transportation modes. Overall average daily personal exposure to BC from those microenvironments was 5.46 µg/h. The highest BC exposure was during commuting 13.48 µg/h and 5.74 µg/h for the motorcyclist and car driver, respectively.

The Payas region bauxite deposits occur as a sandwiched layer that is a few kilometers long and an average of 10 m thick between the lower and upper Cretaceous carbonates of the Arabian Platform. The bauxites occur as 2 types, comprising blanket and pocket, are chemically and texturally homogeneous, and have a thrust structure with ophiolitic mélange formations. The bauxite varies in color, from reddish-brown to grayish-green to black, and has a massive, patchy, and very rare oolitic-pisolitic texture.

The objectives of this study were to investigate the potential biological activities of black cumin seed oil (BCSO) and wheat germ oil (WGO) on different cell lines. Initially, commercially available BCSO and WGO obtained by supercritical carbon dioxide extraction were analyzed in terms of tocopherol, aliphatic alcohols, and thymoquinone content via HPLC and GC analysis. Cell free antioxidant activities and total phenolic content of both oils were detected by DPPH assay and Folin–Ciocalteu method, respectively.

Mesoporous polyethylene glycol (PEG)/silica and carbon black (CB)/silica xerogel composites were prepared by the solgel method as an adsorbent for CO2 adsorption. The CO2 adsorption process was carried out under pure CO2 atmosphere at room temperature in addition to ambient air. The xerogel composites with high surface area and pore volume showed better CO2 adsorption capacity than the pure silica xerogel. After modifying samples with propylene diamine using the wet impregnation method, an increase in CO2 adsorption capacity was observed for the samples except CB/silica xerogel composite.

The aim of the current study was to examine the effect of black ash carbon nanofibers (CNFs) on gamma-aminobutyric acid (GABA) shunt pathway in germinating seeds of tomato (Lycopersicon esculentum Mill., c.v. Rohaba) under salt stress. Seed’s germination pattern, seed moisture content, GABA shunt metabolite levels (GABA, Glutamate and Alanine), total proteins and total carbohydrates, and the level of oxidative damage in response to sodium chloride (NaCl) treatments were determined.

The results showed that AGC stocks were significantly lower than SOC, normally ranging from 9.9 to 29.55 tons ha-1 . Using the Walkley-Black method, the total SOC was estimated at the range of 81.76 to 323.83 tons ha-1 (with an average of 161.47±15.85 tons ha-1 ), which indicated a strong relationship between tree density and SOC. In addition, using the IDW interpolation method, this study estimated that the total CO2 absorbed by mangrove forests was 1,631,834 tons in Bang La and Dai Hop.

Titanium dioxide (TiO2) and carbon black (CB) nanoparticles (NPs) have biological effects that could aggravate pulmonary emphysema. The aim of this study was to evaluate whether pulmonary administration of TiO2 or CB NPs in rats could induce and/or aggravate elastase-induced emphysema, and to investigate the underlying molecular mechanisms.

In this preliminary study, black spinel-carbon nanocomposite was synthesized and investigated for improved solar radiation absorbance aimed for the solar-driven integrated MD seawater desalination process. The black spinel-carbon nanocomposites were based on black spinel CuCr2O4 doped with various Fe3+ content. The black spinel-carbon nanocomposite was synthesized using the hydrothermal method and was characterized with respects to structural morphology and radiation absorbance properties.

Integrated nutrient management system (INMS) gained importance not only in increased yield of crops but also in maintaining the soil health and fertility. Keeping these in views a field experiment was conducted at Mountain research centre for field crops Khudwani (SKUAST-Kashmir) during 2013 (in progress since march 2008) to study the Effect of INM on soil carbon pools and soil quality in rice-brown sarson cropping system with different treatment combinations.
