Summary: A single-crystalline silicon nanobelt field-effect transistor (SiNB FET) device was developed for pH and biomolecule sensing, with buffer concentration shown to affect sensitivity and stability. The sensor demonstrated sensitivity to solution pH and AFP, with results indicating a negative relationship between buffer concentration and sensor sensitivity. Surface functionalization was found to impact AFP sensing effectiveness, with buffer concentration influencing current shifts in the sensor. Overall, buffer concentration plays a crucial role in the sensitivity and stability of the SiNB FET device in chemical and biomolecular sensing.

Summary: The study demonstrated that modifying bitumen emulsion with nanosilica can enhance the moisture susceptibility and mechanical performance of asphalt mixtures by improving the bitumen cohesion and adhesion with aggregates. The addition of nanosilica significantly increased the indirect tensile strength and compressive strength of the samples, as well as the secant stiffness modulus, while reducing the failure strain against lateral deformation. Statistical analysis also confirmed the significant effect of nanosilica addition on reducing moisture susceptibility and improving mechanical performance of asphalt emulsion mixtures.

Summary: This study compares the pH sensing performance of non-functionalized carbon nanotubes (CNT) field-effect transistors (p-CNTFET) and CNTFET functionalized with a conjugated polyfluorene polymer (f-CNTFET). The results show that p-CNTFETs exhibit a linear, reversible pH response in phosphate buffer solutions (PBS), while f-CNTFETs have a stronger pH response in both PBS and borate buffer solutions (BBS). The performance of f-CNTFET exceeds the current state-of-the-art in BBS.

Summary: This study investigated sonochemical degradation of surfactants with different charge types, and found that the degradation rate increased with increasing initial bulk concentration until reaching a maximum value. The initial bulk concentration to obtain the maximum degradation rate was positively correlated with the critical micelle concentration (cmc). Anionic surfactants had lower initial bulk concentrations compared to their cmcs, while cationic surfactants had higher initial bulk concentrations than their cmcs, which can be explained by the negatively charged cavity surface and the effect of the coexisting counterions of the surfactants.

Summary: Since the first chemical fluorescent sensor reported in 1867, research has been ongoing to find intelligent organic molecules that can act as high selective and sensitive chemical sensors. Various methods, such as colorimetric and fluorescence techniques, have been used to develop and study new nitroquinolinic compounds with potential recognition capabilities against different solvents, pH levels, and organic/inorganic salts. Spectroscopic and spectrometric techniques were employed for structural characterization, while UV-Vis and fluorescence measurements confirmed the binding/interaction processes of ionic species, showing sensitivity to pH and solvents. The combination of theory and experiment, including DFT calculations, provided a better understanding of behavior in acidic, basic, and neutral environments.

Summary: Buffers are widely used in soil enzyme assays to measure specific activities or pH optima, but the pH stabilization capacity of commonly used MUB buffer may deviate significantly in different soils, even with increased concentration. Forcing a specific pH in enzyme activity assays in soils appears difficult, presenting a tension between maintaining pH and maximizing assay sensitivity.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
