AbstractThe application of photocatalytic and self‐cleaning titanium dioxide (TiO2) nanomaterials coating on the stone of architectural heritage (particularly on marble) can be used to preserve their aesthetic qualities. The present work describes the effect of dipping time on the wetting property of coatings and the effect of UV irradiation on the coating in terms of hydrophilicity. The suspension of TiO2‐SiO2 is prepared by adding 30–50 nm in size TiO2 particles in the sol–gel processed SiO2 solution. The water contact angle (WCA) decreases with increasing dipping time of piece of marble in TiO2 – SiO2 suspension. Also the hydrophilicity of coating increases with increasing UV illumination time. The 2D and 3D laser microscope analysis revealed surface structure and stable surface roughness of 1.0 µm. Such type of superhydrophilic TiO2 – SiO2 coating may be used to protect architectural heritage and buildings.

AbstractBreast cancer is one of the major causes of increased deaths and it is the focus of researchers across the world. Bacteria are harmful to create human diseases like cholera, jaundice. It is needful to control the growth of harmful bacteria. Andrographis alata is rarely presented, widely used in tribal people, and it is also useful to many diseases. These studies are focused on the control the growth of (Gram‐positive (G+ve) and negative (G−ve)) bacteria, and evaluate the anticancer activity against the MCF‐7 cell line using TiO2 nanoparticles (NPs). TiO2 NPs is prepared via A. alata leaf extract. The synthesized TiO2 NPs are characterized by Fourier‐transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), and transmission electron microscope (TEM). Antibacterial activity is carried out by disc diffusion method. The anti‐breast cancer activity (MCF‐7 cell line) is determined via MTT assay. The antibacterial activities of TiO2 NPs are tested against the G+ve (Streptococcus pneumonia and Bacillus cereus) and G−ve (Pseudomonas aeruginosa and Escherichia coli). The greatest zone of inhibition is observed in B. cereus (15 mm) and E. coli (18 mm) at 50 µL. In vitro anticancer efficiency (IC50) of synthesized TiO2 NPs shows good anticancer activity against the MCF‐7 cancer cell line. The prepared NPs show potent antibacterial (foodborne pathogens) and anticancer (MCF‐7) activities, so TiO2 NPs will be useful in biomedical applications.

Published: December 2021

AbstractAn environmentally benign methodology for the regioselective synthesis of an important class of imidazoheterocycles has been developed using choline chloride‐based deep eutectic solvent. It involves the coupling of 2‐amnopyrimidines, 2‐aminopyridines, and 2‐aminopyrazines with 2‐halocarbonyl compounds to get a variety of substituted imidazopyrimidines, imidazopyridines, and imidazopyrazines, respectively. This method is found to be expeditious, catalyst‐free, energy‐efficient with good yields of products and potential for scale‐up. Moreover, the eutectic solvent is inexpensive, biodegradable, non‐toxic, and recycled five times without any considerable loss in its activity.

AbstractCobalt substituted zinc ferrite aluminate series with compositional formula Zn1‐xCoxFeAlO4 (x = 0.0, 0.2, 0.4, and 0.6) is prepared by chemical sol–gel synthesis. The prepared samples are characterized by X‐ray diffraction (XRD), transmission electron microscope (TEM) technique. A cubic spinel phase is revealed by XRD analysis and confirmed from selected area electron diffraction (SAED) pattern. The true values of lattice constant are obtained from Nelson–Riley extrapolation plot, and lattice strain values are obtained with the help of Williamson‐Hall equation. The TEM image confirms average crystallite size of 31 nm. The dielectric study discloses the decrease of dielectric constant and loss tangent with the increasing frequency of applied field.

AbstractPresent work depicts the progress of cadmium oxide (CdO)‐polyaniline composites synthesized by chemical oxidative technique. The composites with change in CdO composition are subjected to structural, electrical, dielectric, and morphology using X‐ray diffraction, AC conductivity, and scanning electron microscopy. The thermogravimetric analysis carried out to study the thermal stability, which shows that the composite with highest CdO concentration displays better stability. The electrical conductivity of the modified polyaniline tends to change with change in the frequency indicating hopping of charge carriers as a dominant mechanism. The variation of dielectric constant of all modified polyaniline with respect to the frequency is analyzed at room temperature. The dielectric constant is found to increase with the decrease in CdO concentration and is found to highest for composite with 2% CdO.

AbstractIron oxide (Fe2O3) nanoparticles are synthesized by novel, swift, extremely simple, requiring enormously less preparation time, and a financially savvy process called an ASH Supported method and utilized for expelling arsenic from water. A simulated sample of arsenic(III) of known concentration is prepared in the laboratory. This simulated sample of arsenic is treated with two different concentrations and phases of iron oxide nanoparticles for two different reaction times (1 and 24 h). Fe2O3 nanoparticles are observed in two phases, namely mixed and pure phase, in nanosized range confirmed by angle dispersive X‐ray diffraction (ADXRD). These nanoparticles are found to have 99% sorption efficiency and the highest adsorption capacity of 964 mg g−1 for arsenic(III) than reported earlier in any literature. The results show that 0.1 mg of Fe2O3 nanoparticles effectively remove arsenic(III) from the simulated water sample for 1 h reaction time. The maximum adsorption is obtained at a 7.0 pH value for minimal ionic strength. This article also renders that the arsenic removal is phase induced rather than size induced. Arsenic(III) removal by iron oxide nanoparticles synthesized by the above‐mentioned method is reported for the first time and this is the main attraction of the present work.

AbstractThe structures of ZnO nanoparticles (NPs) of different morphology (rod, flower, and grains) using Zinc chloride and zinc nitrate synthesis are carried out under ambient conditions. In this investigation, we report that ZnO NPs are effectively synthesized and exploited to exhibit the morphological effect of ZnO NPS on its reduction in photocatalytic methylene blue (MB) dye‐degradation. UV–Visible spectra studies of the prepared ZnO NPs confirm the absorption peak at 377, 376.3, and 376 nm representative of the formation of ZnO NPs. Powder X‐ray diffraction (XRD) results demonstrate that the strong, highly intense, and narrow‐width diffraction peaks indicate the most stable crystalline hexagonal (Wurtzite) structure of ZnO NPs of rod, flower, and grains with average size about 20, 16.62, and 18.02 nm in diameter, respectively. According to field emission‐scanning electron microscopy (FE‐SEM), results confirm the development of ZnO NPs. In addition, the degradation efficiency of MB dye by ZnO (grain) reveals larger enhancement than the rod and flower with the highest adsorption of color after 0.067 min−1.This study offers the mainstep forward in the field of diluted wastewaters in textile industries.

AbstractNanograined zinc oxide (ZnO) thin films are synthesized by successive ionic layer adsorption and reaction (SILAR) method. The structural analysis reveals synthesized films show phase pure ZnO with wurtzite crystal structure. The deposited ZnO thin films show interconnected nanograins with porous morphology. The ZnO films exposes liquefied petroleum gas (LPG) and shows gas response of 18% under the exposure of 2600 ppm LPG at 673 K. The palladium (Pd) sensitization significantly improves the LPG sensing properties. The Pd sensitization improves gas response up to 80% under exposure of 5200 ppm at 498 K. The response and recovery time are 60 and 50 s, respectively.

AbstractThe Co doped Li0.5Fe2.5O4 ferrites are successfully prepared by using sol–gel synthetic process. The resulting nanosample is characterized by using XRD and SEM technique. The x‐ray diffraction (XRD) analysis studies clearly suggest the formation of single phase nanomaterials. The SEM analysis indicates the formation of uniform and fine grains like morphology in mixed‐metal oxides. The results of combustion synthesis elucidate that the fuel to oxidizer ratio is the most effective factor for the formation and surface morphology of mixed‐metal oxides. The synthesized Co doped Li0.5Fe2.5O4 ferrite is used for the adsorption studies of methyl orange dye by batch experiments. It is found from the adsorption studies that the removal percentage of Methyl orange is much better. Li0.5Fe2.5O4 particles are good adsorbent materials for removal of methyl orange dyes as compare to the Co doped Li0.5Fe2.5O4 nanopowder. However, the adsorption capacity of Li0.5Fe2.5O4 can be lower by doping with cobalt.

AbstractBackgroundClear cell sarcoma of soft tissue (CCS), epithelioid sarcoma, and synovial sarcoma are rare tumors historically identified as high risk for lymph node metastasis. This study investigates incident nodal metastasis and associated survival in children and young adults with these subtypes.ProcedureUsing the National Cancer Database (2004–2015), we created a retrospective cohort of 1303 patients (aged ≤25 years) who underwent local control therapy for CCS, epithelioid sarcoma, and synovial sarcoma. Kaplan–Meier curves estimated overall survival (OS) by subtype. Stratifying on subtype, Cox regressions assessed OS by lymph node sampling status and nodal metastasis.ResultsThere were 103 (7.9%) patients with CCS, 221 (17.0%) with epithelioid sarcoma, and 979 (75.1%) with synovial sarcoma. Lymph node sampling was more frequent in patients with CCS (56.3%) and epithelioid sarcoma (52.5%) versus synovial sarcoma (20.5%, p < .001). Synovial sarcoma metastasized to lymph nodes less frequently than CCS or epithelioid sarcoma (2.1% vs. 14.6% and 14.9%, p < .001). Across all subtypes, lymph node metastasis was associated with inferior OS (HR 2.02, CI 1.38–2.95, p < .001). Lymph node sampling was associated with improved OS in CCS (HR 0.35, CI: 0.15–0.78, p = .010), inferior OS in synovial sarcoma (HR 1.60, CI: 1.13–2.25, p = .007), and no statistical association with OS in epithelioid sarcoma.ConclusionsLymph node metastasis is rare in children and young adults with synovial sarcoma. Lymph node sampling procedures were not consistently performed for patients with CCS or epithelioid sarcoma, but improved OS supports routine lymph node sampling in children and young adults with CCS.

AbstractBackgroundMature aggressive B‐cell lymphomas are heterogenous malignancies that make up more than half of all diagnosed non‐Hodgkin lymphoma in children and adolescents. The overall survival rate increased over the last decades to 80%–90% due to fine tuning of polychemotherapy. However, new therapeutic implications are needed to further increase the overall survival. Current clinical trials analyze the therapeutic effect of rituximab in pediatric patients, while the mechanism of action in vivo is still not fully understood.MethodsEffector molecules important for tumor defense were analyzed before and at day 5 after rituximab treatment via flow cytometry. Serum rituximab levels were measured with an ELISA.ResultsWe evaluated patient parameters that may affect treatment response in relation to rituximab administration and serum rituximab levels. We indeed found a reduction of Fcγ receptor (FcγR) II levels after rituximab treatment in monocyte subtypes, whereas FcγRI expression was significantly increased. Serum levels of proinflammatory marker proteins S100A8/A9 and S100A12 significantly decreased after treatment to normal levels from an overall proinflammatory state before treatment. CD57, perforin, and granzyme B expression decreased after treatment, comprising a less cytolytic natural killer (NK) cell population.ConclusionThe highlighted effects of rituximab treatment on patient's immune response help in understanding the biology behind tumor defense mechanisms and effector function. After subsequent studies, these novel insights might be translated into patient care and could contribute to improve treatment of pediatric patients with mature aggressive B‐cell lymphoma.

Published: December 2021

AbstractJute fiber with high content and large aspect ratio is directly used to prepare PLA composites to show the effect on structure and properties. By comparing with bamboo powder, it is found that the large aspect ratio of jute fiber is helpful to form a crisscross structure in PLA composites to provide a strong framework. And the larger amount of jute fiber leads to the stronger framework in the PLA composites. Accordingly, the high comprehensive mechanical properties are produced of the PLA composites with jute fiber. Only through the simple blending of 70% jute fiber and PLA, the flexural strength and flexural modulus respectively reach 94.0 ± 4.4 MPa and 9116.7 ± 127.2 MPa, which obviously exceed the mechanical properties of PLA/bamboo blends. The addition of jute fiber also improves the thermal resistance of PLA composites as well as the crystallization ability and perfection of PLA. All the results exhibit the advantages of high content filling of jute fiber with large aspect ratio to modify PLA. Utilization of biomass filler with high content and large aspect ratio will provide an important methodology to expand the application capacity of fully degradable composites in many areas.
Microswimmers from Scalable Galvanic Displacement

Published: December 2021

AbstractMicroswimmers are small particles capable of converting available energy sources into propulsion owing to their compositional asymmetry, and are promising for applications ranging from targeted delivery to enhanced mixing at the microscale. However, current fabrication techniques demonstrate limited scalability and/or rely on the excessive use of expensive precursor materials. Here, a scalable Pickering‐wax emulsion technique is combined with galvanic electrochemistry, to grow platinum films from copper nanoparticles asymmetrically seeded onto SiO2 microparticle supports. In this manner, large quantities of Pt‐SiO2 Janus microswimmers are obtained. Utilizing copper as a templating material not only has the potential to reduce synthesis time, material costs, and toxic waste, but also facilitates the further extension of this methodology to a range of functional materials. This electrochemical approach builds upon previous attempts to overcome the current limitations in microswimmer synthesis and offers exciting opportunities for their future development.

Published: December 2021

AbstractSecurity threats have increased in recent years. To motivate the developers to stick to the security policies, the notion of usable security is investigated. Enhancing the usability of security services leads to developing software products that are resilient against security threats. In this paper, we investigate the role of usable security in developers' intention toward fulfilling the security considerations through the development process. To study this, we conducted empirical research on 25 experts in the field of software development. We proposed a model for analyzing the research outcome using statistical inference based on an extension of the theory of planned behavior. In particular, we posit that attitude toward the development of usable services, subjective norms, and moral obligation are determinants of intention to develop usable security services. We developed 11 security services that are used in the development of service‐oriented software. We asked the experts to integrate the security services in the software and studied the integration process using a detailed questionnaire. The findings indicate a strong positive influence of all correlations, which describe developers' intentions to develop usable secure services to 52%. Our insights enhance the understanding of developers' intentions toward developing usable secure services and their fulfillment.
Non‐secreting parathyroid carcinoma in a dog
Authors: Tremolada Giovanni , Schaffer Paula , Pitt Kathryne 
Published: December 2021

AbstractParathyroid carcinoma is a rare condition affecting dogs. These tumour types are most commonly not palpable on physical exam and cause hypercalcaemia. Patients with this tumour usually present for clinical signs related to their hypercalcaemic status. This case report describes the first case of a dog with a palpable ventral cervical mass diagnosed as a non‐secreting parathyroid carcinoma. After surgical excision and adjuvant chemotherapy, the dog was alive and presumed disease‐free 16 months after surgery. The prognosis in the dog presented here with non‐secreting parathyroid carcinoma seems to be favourable, but the role of adjunctive chemotherapy is still uncertain. A non‐secreting parathyroid carcinoma should be included as a differential diagnosis in dogs presenting with a ventral cervical mass and no evidence of hypercalcaemia.
Parameter estimation and uncertainty analysis in hydrological modeling
Authors: Herrera Paulo A. , Marazuela Miguel Angel , Hofmann Thilo 
Published: December 2021

AbstractNowadays, mathematical models of hydrological systems are used routinely to guide decision making in diverse subjects, such as: environmental and risk assessments, design of remediation strategies for contaminated sites, and evaluation of the impact of climate change on water resources. The correct development and use of them is relevant beyond the realm of hydrology. The continuous improvement in computational power and data collection are leading to the development of increasingly complex models, which integrate multiple coupled physical processes to achieve a better representation of the modeled system. Most of the parameters included in models are difficult to measure directly, so they must be estimated from collected data through a calibration procedure. Furthermore, when models are used to make forecasts about future or hypothetical scenarios, it is important to bound the uncertainty of their results. Therefore, the application of systematic approaches for parameter estimation, sensitivity, and uncertainty analysis to integrate data and models and quantify potential errors, is more necessary now than it was in the past. Even though methodological frameworks for these purposes exist, they have had a slow adoption due to their high computational cost and the required technical knowledge to apply them. We analyze existing methodologies, discuss remaining challenges, and present a survey of emerging trends for the application of parameter estimation and uncertainty analysis in hydrological modeling. Thus, the main objective of this overview article is contributing to improving the quality of models and to their correct use as support tools for decision‐making.This article is categorized under:

CUBIC DIRAC OPERATORS AND THE STRANGE FREUDENTHAL–DE VRIES FORMULA FOR COLOUR LIE ALGEBRAS
Authors: MEYER PHILIPPE 
Published: December 2021

AbstractThe aim of this paper is to define cubic Dirac operators for colour Lie algebras. We give a necessary and sufficient condition to construct a colour Lie algebra from an ϵ-orthogonal representation of an ϵ-quadratic colour Lie algebra. This is used to prove a strange Freudenthal–de Vries formula for basic colour Lie algebras as well as a Parthasarathy formula for cubic Dirac operators of colour Lie algebras. We calculate the cohomology induced by this Dirac operator, analogously to the algebraic Vogan conjecture proved by Huang and Pandžić.
