Summary: This study reports a simple and inexpensive method to achieve impurity-free MOF film deposition on nonconductive poly(ether sulfone) (PES) membranes. The proposed strategy allows the generation of MOF units on the membrane-electrolyte interface through the counter-diffusion of ions, resulting in the deposition of a pure MOF film on untreated polymer membranes.

Summary: This study proposes a new single-stage technique for creating functional surfaces on machined components through a powder mixed EDM process. A comparative analysis of surfaces generated by MoS2 powders of two different sizes, 40 μm (μP) and 90 nm (nP), mixed into the dielectric of EDM is explored. The input parameter chosen is current (Ip), and its effect on Rq, Rsk, Rku, recast layer thickness (RCLT), and EDS analysis of AISI 304 machined surface is assessed. The results show that the Rq increases proportionally with the rise in Ip for both μP and nP mixed dielectrics. At smaller magnitudes of Ip, a unique combination of negatively skewed and positively kurtotic surfaces are generated in both μP and nP mixed dielectrics. The RCLT increases with increasing Ip magnitudes, and the deposition of MoS2 on the machined surface is observed through EDS profiles.

Summary: In this study, spinel-phase Zn2Ga3-xFex3+Ge0.75O8 and Zn2Ga2.98-xFex3+Cr0.02Ge0.75O8 nanoparticles were prepared by one-step hydrothermal method in combination with vacuum annealing. Fe3+ doping influences the generation of (Ga-Zn(0) -Zn'(Ga)) defects and the afterglow time. NIR persistent luminescence can be observed in Fe3+ and Cr3+ co-doped ZGGO nanoparticles, with a longer afterglow time. ZGGO: Cr3+, Fe3+ nanoprobes show potential applications in autofluorescence-free imaging and MRI.

Summary: This paper presents a novel approach of using reduced graphene oxide as a reducing agent for Au(III) chloride complex ions to fabricate composite material Au@GO(r) in a single-step process. The reduction process was performed under high pressure and high temperature conditions, resulting in gold nanoparticles with an average diameter below 3 nm. The advantage of using reduced graphene oxide lies in its high surface area, which significantly accelerates the reaction rate. Green chemistry metrics and circularity indicators were used to assess the environmental friendliness and sustainability of the process, with an atom economy score of 99%.

Summary: Hydrogen peroxide sensors were made through a single printing step with carbon ink containing catalytically synthesized Prussian blue nanoparticles. The resulting bulk-modified sensors had a wider linear calibration range and a lower detection limit compared to surface-modified sensors, due to decreased noise and increased signal-to-noise ratio. The glucose and lactate biosensors based on these sensors showed similar or higher sensitivities compared to surface-modified biosensors.

Summary: We synthesized a carbon nanotubes-en-capsulated Ni nanoparticles catalyst through a facile chemical vapor deposition approach for electrochemical CO2 reduction (ECR). The Ni@N-C catalyst exhibited the highest CO Faraday efficiency (FECO%) of 90% at -0.77 V vs. RHE in the H-type cell. Moreover, it showed a high FECO% of over 93% within the range of -0.37 to -0.77 V vs. RHE in the flow cell. The excellent catalytic performance of Ni@N-C suggests that N-doped carbon nanotubes coated on Ni nanoparticles play a vital role in promoting ECR activity. This work provides insights into the development of a simple and efficient electrocatalyst for ECR.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.

Summary: Molecular docking (MD) analysis is widely used for studying the interaction between aptamers and small molecules. This study established steady-state aptamers of tertiary structures (SATS) using specific aptamers of tetracycline antibiotics as docking models. Molecular docking results revealed multiple binding sites in the SATS of aptamers, with significant variations in binding free energy (BFE) and docking score (DS). The study also proposed a method for MD analysis based on SATS, providing insights into binding mode and predicting binding sites.
