<p style="text-align:left;"><span style="font-size:14pt;"><em><strong>Abstract:</strong><br /> Catalytic conversions of carbon dioxide (CO2) into carbon monoxide as well as other hydrocarbons through hydrogenation of carbon dioxide, which originates directly from energy sources that are renewable, are regarded as one of the most cost-effective strategies to mitigate global warming and force chemical and energy businesses toward more sustainable resource usage. The CO2 hydrogenation process has recently examined a wide range of heterogeneous catalysts. Due to its outstanding material qualities in several domains, including energy and the environment, TiO2 has received significant interest as a potential photocatalytic material for decades however, its broad bandgap (3-3.2 eV) inhibits light absorption in confined light wavelength ranges, and TiO2 relatively high charge carrier recombination rate is a barrier to efficient photocatalytic CO2 conversion. Similar to how nanostructures have benefits like enhanced light absorption, increased surface area, directed charge transport, and effective charge separation. In addition, methods including hydrogenation, junction creation, and doping have improved photocatalytic performance. Those tactics have the potential to significantly alter the electrical architecture behind the improved spectrum harvesting. Methanol, CO, ethanol, and many more derivatives are produced directly from the hydrogenation of CO2 by examining the catalytic efficiency and reaction mechanism over a variety of heterogeneous catalyst types with a focus on practical considerations. Using TiO2 as the support, Pt NP is able to promote the overall CO2 conversion to enhance the activity of Pt over PtTiO2 is originated from the sites at the Pt-oxide interface, where the synergy between Pt and oxide plays an important role. In this review, we highlight the work done to improve photocatalytic CO2 reduction via both the material and structural modification of TiO2 and TiO2-based photocatalytic systems. Also, we go over various methods for creating TiO2 photocatalysts with a nanostructure for effective CO2 conversion, photocatalyst structure design, and material modification.</em></span></p>

Ammonia as one of the most abundant toxic pollutants has a negative impact on every living being. Trace levels of ammonia can cause serious irritation to sensitive organs such as eyes, skin, and whole respiratory system. Serving as a serious threat for human health and environment, is an imperative to find an efficient strategy for rapid detection and monitoring of gas pollutants. Due to their tunable physicochemical properties, nanomaterials are promising components for sensors development, possessing good gas sensing capabilities.<br /> In this work, ammonia (NH3) sensing performance testing was conducted on sensors based on three different types of irradiated screen-printed electrodes - carbon nanostructures (multi-walled carbon nanotubes - MWCNT and graphene – G) and electroconductive polymer (polyaniline - PANI). The irradiation was applied with 60Co gamma rays at different doses (0, 50 and 100kGy). The testing was performed against NH3 vapors with different concentration (3 and 25%). The electrochemical characterization included resistance change monitoring of the non-irradiated and irradiated electrodes which confirmed conductivity increase for irradiated structures. Best sensing response showed MWCNT electrode irradiated with 100kGy with electrical resistance of around 21M. The electrochemical characterization was followed by physical characterization with scanning electron microscopy (SEM) in order to confirm the irradiation effect on the structure.</em></span></p>

<p style="text-align:left;"><span style="font-size:14pt;"><em><strong>Abstract:</strong><br />Currently, improper application of commercially available chemical fertilizers has created strong barriers to the health of soil as well as entire ecosystem. To feed the expanding population under ever-changing environment, maintaining agriculture output is becoming crucial day by day. Therefore, to reduce the use of inefficient traditional chemical fertilizers, modern agriculture requires novel techniques. In this context, nano enabled slow-release fertilizers may be the best option for nutritional security as well as environmental sustainability. Since few years back, the use of nanomaterials (NMs) in terms of next-generation fertilizers especially the biopolymer-based formulations at optimal dose have been appreciated to increase the nutrient utilization efficiency through a more controlled, and slower nutrient release phenomenon that could better match the sustained nutrient needs of crops across the time. In this regard, chitosan being biocompatible and biodegradable in nature has mostly been studied for crop protection and growth in agriculture for last ten years. Chitosan is a linear biopolymer of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit), derived from the biowaste of seafood industry. It acts as an abundant nutrient source of C (54.4–47.9 wt%), O (42.3–30.19 wt%), N (7.6–5.8 wt%), and P (6.1–3.4 wt%) to plants. In addition, chitosan possesses enough functional groups which can be used to functionalize with active ingredients (AIs).

WC Ball to SiC weight ratio of 10:1 and ≈40% milling jar feed occupancy by volume were kept at a constant. The XRD analysis of milled samples showed that increasing milling speed increased rate of crystal size reduction, amorphization and lattice strain. Optimizing milling conditions led to synthesis of SiC particle in macro, micro, submicron and nano size. Particles milled at 100 and 150rpm were smooth with rounded edges while particles milled above 200 rpm were angular with rough morphology. The variation of particle size in cordierite ceramic structures led to improved thermomechanical properties in ceramics. 15% 200rpm1hr milled SiC ≈1µm resulted to significant improvement of % apparent porosity and bulk density of 12.4% and 1.99 compared to 25.05% and 1.98 samples without SiC respectively. The XRD analysis of SiC laced ceramic samples showed presence of characteristic 2ƟO SiC peaks at ≈35.8, 41, 60 and 70. The enhancement of % apparent porosity and bulk density were attributed to SiC particle size.</em></span></p>

So far, more than 30 types of MXenes materials have been successfully synthesized, and dozens of similar materials have been predicted by computer simulation. The synthesized MXene was analyzed by SEM and TEM to identify the presence of anatase-type titanium dioxide on the surface of MXene. When doped with different weights of urea, it was found that the 0.5g of urea doped MXene material showed a strong ability to photo-catalytically decompose phenol under visible light, and the decomposition rate reached above 85% within 3 hours. However, the performance of N-TiO2-MXene for phenol degradation under visible light was poor at lower pH and higher ionic concentrations. Moreover, through free radical shielding experiments, it was determined that the dominant free radicals were ◦OH, O2- and holes for phenol degradation. This study demonstrates that the N-TiO2-MXene produced in this experiment can be used for environmental applications.</em></span></p>

<p style="text-align:left;"><span style="font-size:14pt;"><em><strong>Abstract:</strong><br /> Carbon dioxide (CO2) is a double-edged sword. Although it helps create a warm environment on Earth, the excessive burning of fossil fuels has led to a continuous rise in CO2 concentration in the atmosphere, resulting in irreversible climate changes [1, 2]. High entropy materials, which consist of various elements in single-phase compounds, are known for their unique properties and crystal structures due to their high configurational entropy. The recent research trend has focused on utilizing nanostructured ceria (CeO2) in various applications due to its availability, affordability, and stability. It has been found that this rare earth oxide has the potential to be used in photocatalytic applications, including energy production, hydrogen generation, oxygen evolution, and storage capacity enhancement [3, 4].<br /> In our research, we prepared six ceria-based rare earth high-entropy oxides (HEOs) with fluorite structure and examined their photocatalytic behavior toward CO2 hydrogenation. The cationic site in the fluorite lattice consists of five equimolar elements, including Sm, Ce, Pr, La, and Nd (rare earth elements) and Y and Zr (transition metals). The HEOs exhibit band gaps ranging from 2.65 to 3.37 eV and appropriate valence and conduction band positions for CO2 reduction. The samples possess high photocatalytic activity, which can be attributed predominantly to the accessibility of more active sites, resulting in more photogenerated electrons. The materials produced carbon monoxide as the main product, but some methane and methanol were also generated. The photocatalytic performance of all studied HEOs surpasses single fluorite oxides or equivalent mixed oxides. The Ce0.2Zr0.2La0.2Nd0.2Sm0.2O2 (CZLNS) showed the highest photocatalytic conversion of CO2 (29.7 %) and formation rate for CO (1256.1 nmol) among the HEO samples and its pristine CeO2 counterpart (6.6 %).

<p style="text-align:left;"><span style="font-size:14pt;"><em><strong>Abstract:</strong><br /> In recent years, research has increased to implement nanomaterials in different areas, especially health. However, the methods used to obtain nanoparticles involve sophisticated equipment that increases production costs and chemicals that can be toxic. The alternative for nanoparticle synthesis is the biological method because it reduces these disadvantages and provides biofunctionalization. In this sense, silver and silver chloride nanoparticles (AgNPs and AgClNPs) have shown antibacterial activity against human pathogens. Therefore, in this project, silver-based nanomaterials were synthesized and characterized using the aqueous extract of Coffea arabica green beans. By UV-Vis spectroscopy, bands at 361 and 430nm corresponding to AgClNPs and AgNPs, respectively, were observed. X-ray diffraction analysis allowed the identification of the cubic structure centered on the faces at the 2 theta angles of 38.16°, 44.38° and 64.66° corresponding to the Bragg refraction of (111), (200) and (220), respectively, characteristic of AgNPs and at 46.31°, 54.92° and 57.55° assigned to the (220), (311) and (222) planes of the AgClNPs. In dynamic light scattering analysis, particle sizes greater than 100 nm were determined; however, using TEM, agglomerates of particles with sizes of 20-50 nm surrounded by organic material from the C. arabica extract were observed. The nanoparticles showed antioxidant activity against the DPPH radical and antibacterial activity against E. coli and B. subtilis, regarding the minimum bactericidal concentration of 250ppm for both strains.</em></span></p>

<p style="text-align:left;"><span style="font-size:14pt;"><em><strong>Abstract:</strong><br />Tungsten trioxide (WO3) film is commonly used to create electrochromic devices since it is one of the most promising electrochromic materials with good electrochemical properties. Here, we synthesize amorphous Bi-doped WO3 (Bi-WO3) films with improved electrochromic (EC) performance utilizing a straightforward sol-gel approach. With the right Bi element doping quantity and thickness, the EC performances can be greatly enhanced. High optical contrast (T = 73.06% at 630 nm), quick switching time (3.6/1.4 s for coloring and bleaching at 630 nm), and high coloration efficiency (52.52 cm2/C at 630 nm) were all features of the optimized Bi-WO3 hybrid film that contributed to its remarkable electrochromic performance. The fascinating EC performance of the film can be explained by its structure and electrochemical properties, which reveal that the film's amorphous structure and overall biased (002) crystal plane orientation result in large, ordered ion channels. The straightforward procedure and respectable sample qualities offered a practical method for the quick processing of high-performing EC materials and devices.</em></span></p>

According to our previous experiments, SWCNT does not affect the growth kinetics of the non-autolytic bacteria so far investigated. However, in the case of our autolytic Staphylococcus aureus strain SWCNT resulted in a change in the bacterial growth curve: it became elongated resulting in a longer reproduction time. This observation is also confirmed by the CCK-8 viability assay.</em></span></p>

Turmeric contains variety of ingredients but most important curcumin. The curcumin is insoluble in water medium due to which its applications are limited. Poor bioavailability of curcumin in body leads to its poor activity, low absorption and rapid elimination from the system. This is a major obstacle in making a drug for clinical trials. So researchers are trying to increase the solubility of curcumin in aqueous medium.<br />In the current work different nanopartciles i.e. gold, silver, silica etc have been used for improving the solubility of curcumin. A simple wet chemical method has been utilized for the synthesis curcumin conjugation with various nanoparticles. The synthesized curcumin conjugated nanoparticles have been analyzed by various characterization tools such as UV-Vis spectroscopy, FTIR, SEM/TEM etc.<br />The synthesized conjugate can be utilized for testing antibacterial, antimicrobial, anticancer application.</em></span></p></div>NP2023-004 A comparative study of the toxic effect of ZIF‑8 and ZIF‑L on the colonization and decomposition of shaded outdoor mice carrions by arthropodshttps://www.nanopaprika.eu/groups/nanoposter2023/forum/topics/np2023-0042023-02-21T10:36:16.000Z2023-02-21T10:36:16.000ZTINChttps://www.nanopaprika.eu/members/TINC<div><p style="text-align:center;"><span style="font-size:14pt;"><strong>A comparative study of the toxic effect of ZIF‑8 and ZIF‑L on the colonization and decomposition of shaded outdoor mice carrions by arthropods</strong></span></p>
