Herein we reviewed Titanium dioxide (TiO2) nanoparticles and how they are applied in the photocatalytic splitting of water to generate hydrogen but also to remove both organic and inorganic pollutants. Hydrogen generation through the splitting of water by TiO2 which is a cheap, efficient, and non-toxic photocatalyst has found wide application in clean energy production. The efficiency of the photocatalyst can be improved by using water or sacrificial agents as electron donors, thereby enhancing hydrogen production. In addition, this review explores the fundamental principles, mechanisms, and applications of TiO2-based photocatalysis. It further, highlights the structural properties, bandgap engineering, and surface modifications that influence the catalytic activity of TiO2. Additionally, we discuss the doping of TiO2 with both metals and non-metals to narrow the energy band gap which lowers the recombination effects. Finally, it introduces the potential applications of TiO2-based photocatalysis in the photodegradation of organic and inorganic pollutants.

Published: October 2024

Wood apple (Feronia limonia L.; Rutaceae family) commonly known as poor man’s fruit in India due to its several nutraceutical importance, is native to South India and Sri Lanka. Sanskrit term, “kapittha,” receives several mentions in a number of ancient texts including “Hinduism: an Alphabetical Guide”. Buddhist scholar mentioned wood apple as an Indian fruit while, military commander and poet Chauvundaraya (940-989AD) listed wood apple in numerous medicinal remedies and also mentioned in Charak Samhita and Sushruta Samhita. Wood apple has been planted extensively or being allowed to grow naturally in the reserved forests throughout Southeast Asia, Northern Malaysia and on Penang Island. In India, it is more common in Deccan, Maharashtra, Madhya Pradesh, Uttar Pradesh, Chhatishgarh, Bihar, Jharkhand, West Bengal, Rajasthan, Gujarat, Tamil Nadu, Andhra Pradesh, Kerala and Odisha, however, no data is available for its area and production. Unfortunately, the lack of attention has meant that their potential value is under-exploited and they are in danger of continued genetic erosion, ultimately leading to disappearance. Therefore, it is necessary to spread the awareness of its importance among common people and researches to identify superior genotypes, production problems of wood apple for their ex-situ collection, conservation, evaluation and utilization that is being explained by this study after having various literatures available in different forms from different sources. This review article will help future researchers to conserve as well as explore the possible benefits of this crop to the common people harnessing societal value of growers.
Dependence of Generation of Whistler Mode Chorus Emissions on the Temperature Anisotropy and Density of Energetic Electrons in the Earth's Inner Magnetosphere

Published: January 2018

AbstractWe carry out a series of self‐consistent electron hybrid code simulations for the dependence of chorus generation process on the temperature anisotropy and density of energetic electrons in the Earth's inner magnetosphere. We use the same magnetic field gradient in the simulation system and different temperature anisotropy AT for the initial distribution of energetic electrons at the magnetic equator. We conduct 6 sets of simulations for different AT from 4 to 9, changing the initial number density Nh of energetic electrons at the equator in each set of simulations. By analyzing the spectra obtained in the simulation results, we identify chorus elements with rising tones in the results for higher Nh but no distinct chorus in smaller Nh. We compare the simulation results with estimations of the threshold and optimum amplitude proposed by the nonlinear wave growth theory. We find that the chorus generation processes reproduced in the simulation results are consistently explained by the theoretical estimates. We also compare the simulation results with linear growth rates for all simulation runs. We find clear disagreement between the spectral characteristics of reproduced chorus and the predictions by the linear theory. The present study clarifies that the spectra of chorus are essentially different from those predicted by the linear theory and are determined fully by nonlinear processes of wave‐particle interactions in the chorus generation region.

Published: January 2018

AbstractNew maps of S velocity variation for the upper and middle crust making up the northwestern most corner of South America have been developed from cross correlation of ambient seismic noise at 52 broadband stations in the region. Over 1,300 empirical Green's functions, reconstructing the Rayleigh wave portion of the seismic wavefield, were obtained after time and frequency‐domain normalization of the ambient noise recordings and stacking of 48 months of normalized data. Interstation phase and group velocity curves were then measured in the 6–38 s period range and tomographically inverted to produce maps of phase and group velocity variation in a 0.5° × 0.5° grid. Velocity‐depth profiles were developed for each node after simultaneously inverting phase and group velocity curves and combined to produce 3‐D maps of S velocity variation for the region. The S velocity models reveal a ~7 km thick sedimentary cover in the Caribbean region, the Magdalena Valley, and the Cordillera Oriental, as well as crustal thicknesses in the Pacific and Caribbean region under ~35 km, consistent with previous studies. They also display zones of slow velocity at 25–35 km depth under regions of both active and inactive volcanism, suggesting the presence of melts that carry the signature of segmented subduction into the overriding plate. A low‐velocity zone in the same depth range is imaged under the Lower Magdalena Basin in the Caribbean region, which may represent either sublithospheric melts ponding at midcrustal levels after breaching through a fractured Caribbean flat slab or fluid migration through major faults within the Caribbean crust.

Published: January 2018

AbstractDecision‐Making Under Uncertainty (DMUU) approaches have been less utilized in developing countries than developed countries for water resources contexts. High climate vulnerability and rapid socioeconomic change often characterize developing country contexts, making DMUU approaches relevant. We develop an iterative multi‐method DMUU approach, including scenario generation, coproduction with stakeholders and water resources modeling. We apply this approach to explore the robustness of adaptation options and pathways against future climate and socioeconomic uncertainties in the Cauvery River Basin in Karnataka, India. A water resources model is calibrated and validated satisfactorily using observed streamflow. Plausible future changes in Indian Summer Monsoon (ISM) precipitation and water demand are used to drive simulations of water resources from 2021 to 2055. Two stakeholder‐identified decision‐critical metrics are examined: a basin‐wide metric comprising legal instream flow requirements for the downstream state of Tamil Nadu, and a local metric comprising water supply reliability to Bangalore city. In model simulations, the ability to satisfy these performance metrics without adaptation is reduced under almost all scenarios. Implementing adaptation options can partially offset the negative impacts of change. Sequencing of options according to stakeholder priorities into Adaptation Pathways affects metric satisfaction. Early focus on agricultural demand management improves the robustness of pathways but trade‐offs emerge between intrabasin and basin‐wide water availability. We demonstrate that the fine balance between water availability and demand is vulnerable to future changes and uncertainty. Despite current and long‐term planning challenges, stakeholders in developing countries may engage meaningfully in coproduction approaches for adaptation decision‐making under deep uncertainty.

Published: January 2018

AbstractEmerging cellular therapies require effective platforms for producing clinically relevant numbers of high‐quality cells. This report introduces a materials‐based approach to improving expansion of T cells, a compelling agent for treatment of cancer and a range of other diseases. The system consists of electrospun fibers, which present activating antibodies to CD3 and CD28. These fibers are effective in activating T cells, initiating expansion, and simplify processing of the cellular product, compared to current bead‐base platforms. In addition, reducing the mechanical rigidity of these fibers enhances expansion of mixed populations of human CD4+ and CD8+ T cells, providing eightfold greater production of cells in each round of cell growth. This platform also rescues expansion of T cells isolated from CLL patients, which often show limited responsiveness and other features resembling exhaustion. By simplifying the process of cell expansion and improving T cell expansion, the system introduced here provides a powerful tool for the development of cellular immunotherapy.

Published: January 2018

AbstractCoherent two‐photon‐excited (TPE) therapy in the near‐infrared (NIR) provides safer cancer treatments than current therapies lacking spatial and temporal selectivities because it is characterized by a 3D spatial resolution of 1 µm3 and very low scattering. In this review, the principle of TPE and its significance in combination with organosilica nanoparticles (NPs) are introduced and then studies involving the design of pioneering TPE‐NIR organosilica nanomaterials are discussed for bioimaging, drug delivery, and photodynamic therapy. Organosilica nanoparticles and their rich and well‐established chemistry, tunable composition, porosity, size, and morphology provide ideal platforms for minimal side‐effect therapies via TPE‐NIR. Mesoporous silica and organosilica nanoparticles endowed with high surface areas can be functionalized to carry hydrophobic and biologically unstable two‐photon absorbers for drug delivery and diagnosis. Currently, most light‐actuated clinical therapeutic applications with NPs involve photodynamic therapy by singlet oxygen generation, but low photosensitizing efficiencies, tumor resistance, and lack of spatial resolution limit their applicability. On the contrary, higher photosensitizing yields, versatile therapies, and a unique spatial resolution are available with engineered two‐photon‐sensitive organosilica particles that selectively impact tumors while healthy tissues remain untouched. Patients suffering pathologies such as retinoblastoma, breast, and skin cancers will greatly benefit from TPE‐NIR ultrasensitive diagnosis and therapy.

Published: January 2018

AbstractWearable bendable bandage‐based sensor and a minimally invasive microneedle biosensor are described toward rapid screening of skin melanoma. These wearable electrochemical sensors are capable of detecting the presence of the tyrosinase (TYR) enzyme cancer biomarker in the presence of its catechol substrate, immobilized on the transducer surface. In the presence of the surface TYR biomarker, the immobilized catechol is rapidly converted to benzoquinone that is detected amperometrically, with a current signal proportional to the TYR level. The flexible epidermal bandage sensor relies on printing stress‐enduring inks which display good resiliency against mechanical deformations, whereas the hollow microneedle device is filled with catechol‐coated carbon paste for assessing tissue TYR levels. The bandage sensor can thus be used directly on the skin whereas microneedle device can reach melanoma tissues under the skin. Both wearable sensors are interfaced to an ultralight flexible electronic board, which transmits data wirelessly to a mobile device. The analytical performance of the resulting bandage and microneedle sensing systems are evaluated using TYR‐containing agarose phantom gel and porcine skin. The new integrated conformal portable sensing platforms hold considerable promise for decentralized melanoma screening, and can be extended to the screening of other key biomarkers in skin moles.
Self‐Calibrating Mechanochromic Fluorescent Polymers Based on Encapsulated Excimer‐Forming Dyes

Published: January 2018

AbstractWhile mechanochemical transduction principles are omnipresent in nature, mimicking these in artificial materials is challenging. The ability to reliably detect the exposure of man‐made objects to mechanical forces is, however, of great interest for many applications, including structural health monitoring and tamper‐proof packaging. A useful concept to achieve mechanochromic responses in polymers is the integration of microcapsules, which rupture upon deformation and release a payload causing a visually detectable response. Herein, it is reported that this approach can be used to create mechanochromic fluorescent materials that show a direct and ratiometric response to mechanical deformation. This can be achieved by filling poly(urea‐formaldehyde) microcapsules with a solution of a photoluminescent aggregachromic cyano‐substituted oligo(p‐phenylene vinylene) and embedding these particles in poly(dimethylsiloxane). The application of mechanical force by way of impact, incision, or tensile deformation opens the microcapsules and releases the fluorophore in the damaged area. Due to excimer formation, the subsequent aggregation of the dye furnishes a detectable fluorescence color change. With the emission from unopened microcapsules as built‐in reference, the approach affords materials that are self‐calibrating. This new concept appears to be readily applicable to a range of polymer matrices and allows for the straightforward assessment of their structural integrity.

Published: January 2018

AbstractGraphene, a 2D sp2‐hybridized carbon sheet is a hot topic in the fields of materials science and chemistry. Here, a symmetrical multilayer architecture of graphene is designed by grafting of sulfonated 4,4′‐ diaminodiphenyl sulfone (SDDS) with the ample sulfonate groups and tunable interlayer spacing to exhibit the Li+ extraction from ionic mixtures with Na+, Mg2+ and Ca2+. Under the application of an electric field, the selective separation of cations can be achieved by controlling the flow channels of negatively charged ions (≈0.48 nm) during the synthesis of rGO‐SDDS‐rGO membrane. The result shows that the ion selectivity of the rGO‐SDDS‐rGO membrane is Na+ > Li+ > Ca2+ > Mg2+ and the absolute separation efficiency values of Li+/Mg2+ and Li+/Ca2+ are as high as 85.32 and 80.81%, respectively.

Published: January 2018

ABSTRACTThis study evaluated the thermal, morphological, chemical, and mechanical properties of virgin and recycled polystyrene. The recycling process was carried out by dissolution of polystyrene (extruded and crystal) in ethyl acetate, followed by two processes for solvent removal: vaporization by direct contact with water at 85 °C in a tubular evaporator and vaporization during the extrusion process. For the samples produced by solvent evaporation in the tubular evaporator, there was practically no degradation on polymer chain, neither reduction in glass transition temperature. For the samples produced by solvent evaporation during the extrusion, a polymer chain degradation was noted by reduction in molar weight and in glass transition temperature. The FTIR evaluation suggests that polymer oxidative degradation, in both samples, was more pronounced in the extruded sample. The removal of plasticizing additives could be evidenced by the glass transition temperature increase in the recycled samples produced in the tubular evaporator. © 2018 Wiley Periodicals, Inc. J.

ObjectiveSystemic lupus erythematosus (SLE) has limited monozygotic twin concordance, implying a role for pathogenic factors other than genetic variation, such as epigenetic changes. Using the disease‐discordant twin model, we investigated genome‐wide DNA methylation changes in sorted CD4+ T cells, monocytes, granulocytes, and B cells in twin pairs with at least 1 SLE‐affected twin.MethodsPeripheral blood obtained from 15 SLE‐affected twin pairs (6 monozygotic and 9 dizygotic) was processed using density‐gradient centrifugation for the granulocyte fraction. CD4+ T cells, monocytes, and B cells were further isolated using magnetic beads. Genome‐wide DNA methylation was analyzed using Infinium HumanMethylation450K BeadChips. When comparing probes from SLE‐affected twins and co‐twins, differential DNA methylation was considered statistically significant when the P value was less than 0.01 and biologically relevant when the median DNA methylation difference was >7%. Findings were validated by pyrosequencing and replicated in an independent case–control sample.ResultsIn paired analyses of twins discordant for SLE restricted to the gene promoter and start region, we identified 55, 327, 247, and 1,628 genes with differentially methylated CpGs in CD4+ T cells, monocytes, granulocytes, and B cells, respectively. All cell types displayed marked hypomethylation in interferon‐regulated genes, such as IFI44L, PARP9, and IFITM1, which was more pronounced in twins who experienced a disease flare within the past 2 years. In contrast to what was observed in the other cell types, differentially methylated CpGs in B cells were predominantly hypermethylated, and the most important upstream regulators included TNF and EP300.ConclusionHypomethylation of interferon‐regulated genes occurs in all major cellular compartments in SLE‐affected twins. The observed B cell promoter hypermethylation is a novel finding with potential significance in SLE pathogenesis.

Published: January 2018

AbstractAmine oxidation is one of the fundamental reactions in organic synthesis as it leads to a variety of value‐added products such as oximes, nitriles, imines, and amides among many others. These products comprise the key N‐containing building blocks in the modern chemical industry, and such transformations, when achieved in the presence of molecular oxygen without using stoichiometric oxidants, are much preferred as they circumvent the production of unwanted wastes. In parallel, the versatility of ruthenium catalysts in various oxidative transformations is well‐documented. Herein, this review focuses on aerobic oxidation of amines specifically by using ruthenium catalysts and highlights the major achievements in this direction and challenges that still need to be addressed.
