Summary: Thermal reduction of sol-gel derived CuWO4 creates Cu-WO3_x composite with enhanced visible light absorption and a metal-metal oxide interface, leading to improved photocatalytic activity in the non-oxidative coupling of methane reaction. This is attributed to the abundant oxygen vacancies and additional visible light absorbance provided by the Cu nanoparticles.

Summary: The precursor gel was prepared using a sol-gel method, and ultrafine TiN was obtained by Fe-catalyzed carbon thermal reduction nitridation reaction. The addition of Fe significantly promoted the reaction, resulting in ultra-fine TiN nanoparticles with an average size of about 24 nm. The promotion effect of Fe is due to its role in providing nucleation sites for amorphous titanium oxide and facilitating the dissociation of N2.

Summary: The properties of potassium hexatitanate (K2Ti6O13, KTO) photocatalyst and the deposited Ag cocatalyst have an influence on the photocatalytic reduction of carbon dioxide to carbon monoxide. The calcination temperature and crystallite size of the KTO sample are positively correlated with the photocatalytic activity. The state of the Ag cocatalyst is also influenced by the calcination temperature, thus affecting the properties of the catalyst. Therefore, the photocatalytic activity is determined by both the properties of the KTO sample and the deposited Ag cocatalyst.

Summary: This study aims to investigate the correlation between the structural properties of different TiO2 catalysts and their photocatalytic performance and selectivity in CO2 reduction at different pH levels. Two types of TiO2 catalysts were prepared and extensively characterized using various techniques. The prepared catalysts exhibited higher selectivity in CO2 reduction compared to a commercial P25 catalyst. The TiSG catalyst, which had the lowest portion of hydroxyl oxygen species, showed the highest photoreduction efficiency. The study also explored the effect of pH on the efficiency and selectivity of photocatalytic CO2 reduction, revealing different product distributions in acidic and basic environments.

Summary: Various non-hydrolytic sol-gel synthesis methods were investigated to selectively produce mesoporous t-ZrO2 or m-ZrO2 with significant specific surface areas. The presence of significant amounts of water favored the formation of m-ZrO2, while strictly non-hydrolytic routes favored the formation of t-ZrO2. The role of water in the structure of zirconia was found to be crucial.

Summary: This study focuses on the photocatalytic degradation of methylene blue (MB) on erbium ion (Er3+) doped TiO2 under visible light. The synthesized (Er3+/TiO2) nanocomposite was characterized and different parameters were studied for the photoreactor (PR) and the synthesized catalyst. The results showed that under UV light, pure TiO2 degraded by 85%, while under visible light, (Er3+/TiO2) achieved a maximum degradation of 77% at pH 5 and improved efficiency at a low motor speed of 40 rpm. However, the degradation efficiency decreased to 70% with an increase in MB concentration.

In vitro and in vivo experiments showed that BCP and BCP/Nb2O5 ceramics were active in promoting bone formation and maturation. Therefore, in cases of tooth loss in children, clinicians should consider using calcium phosphate-based grafts to maintain the dimensions of the alveolar ridge and facilitate future implants.

Summary: We propose semi-analytical solutions that describe the spatial and temporal distributions of temperature and pressure inside low-absorbing dielectrics excited by tightly focused laser beams. These solutions are compared to experimental measurements in water, where variations in the local refractive index due to acoustic waves generated by electrostriction, heat deposition, and the Kerr effect at different temperatures are observed. The experimental results show excellent agreement with the modeling predictions, with electrostriction being the dominant transient effect in acoustic wave generation. Measurements at 4.0 degrees C demonstrate significant reduction in the thermoelastic contribution to the optical signal due to the low thermal expansion coefficient of water at this temperature.

Summary: Growing demand for renewables and sustainable energy production has led to an increased interest in producing high-quality biomethane from biogas. Despite containing methane as the main component, biogas may also contain noncombustible substances such as carbon dioxide, nitrogen, and hydrogen sulfide. These contaminants, particularly CO2 and H2S, can decrease the calorific value of biogas and cause corrosion and wear of pipes and engines. Therefore, it is necessary to remove these compounds from biogas before it can be used for various applications.

Summary: Our research investigated the optical patterns of leaves when exposed to light, studying the interactions of the light with chloroplast pigments and the structural components of leaves. We used six species of variegated leaves to analyze the effects of chlorophylls, carotenoids, and outside-chloroplast components on the behavior of light within the leaf. Our findings revealed high absorbance and scattering at specific wavelengths, which differed depending on the presence or absence of chloroplasts. These differences in light behavior were associated with the penetrability of different wavelengths and the physical mechanisms of internal reflectance and degenerate chlorophyll quantum state.

Summary: This study proposes a hybrid controller that combines concepts of a PID controller with LQR and a feedforward gain to control the positioning of a 2 DOF robotic arm with flexible joints subject to non-ideal excitations. Two cases were studied to evaluate the performance of the controls, with one case involving fixed positioning of the arm and the other case involving rotational movement of the arm. The results of simulations showed that the hybrid controller provides the lowest error for both cases, but is sensitive to variations in the mass of the arm in rotational movements, highlighting the importance of optimal control design.

Numerical results using phase portraits, bifurcation diagrams, Lyapunov exponents, and 0-1 testing confirm chaotic and hyperchaotic behavior. The results also demonstrate the effectiveness of the control, showing errors below 1% even with parametric errors. Additionally, the study explores the system in fractional order, revealing periodic, constant, or chaotic behavior for specific values of the derivative order.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
