Summary: The current development status of impedimetric biosensors using tethered bilayer membranes (tBLMs) as sensing elements was reviewed. Understanding the nature of electrochemical impedance spectroscopy (EIS) response defined by the physical properties of tBLMs is crucial for designing and operating such sensors. Traditional parameters, such as membrane conductance derived from electric equivalent circuits, may not accurately measure the activities of pore-forming agents due to the unique molecular structure and physical properties of the submembrane reservoir and the dependence of measured EIS signals on the lateral 2D distribution of pores (defects) in tBLMs. Controlling the micro-heterogeneity of tBLMs and experimentally measuring the specific resistance of the submembrane reservoir offer a potential way to design robust tBLM biosensors with reproducible signals.

Summary: Lipid droplets (LD) locate in the endoplasmic reticulum membrane and play important roles in biological functions. A protein called ADRP surrounds LDs along with phospholipid monolayers and is involved in storing neutral lipids. This article focuses on the influence of ADRP on the 3D shape of LDs embedded in bilayers and the diffusion of phospholipids on LD surfaces. The study shows that ADRP significantly affects the 3D structure of LDs. Rating: 9/10.

Summary: In this study, biomimetic electrodes suitable for probing protein/phospholipid interactions were created on metallurgically polished aluminum surfaces. The fusion of multilamellar vesicles on the aluminum surface formed a hybrid bilayer lipid membrane (hBLM), with its complex capacitance being typical for intact phospholipid bilayers. The presence of cholesterol in hBLMs inhibited membrane damage caused by the peptide melittin, which showed a concentration-dependent interaction with the hBLMs.

Summary: This article investigates the structure and packaging features of Bi-B-Zn sealing glass with different Bi2O3 concentrations. Increasing the Bi2O3 and Bi/B ratio leads to changes in the glass transition temperature and glass softening temperature. The modification of the glass network structure increases or decreases the [BiO] and [BO] units. Encapsulating a polyimide optical fiber with FBG on 65-manganese steel shows good bonding effect and stable sensing capability of the FBG sensor in a high-temperature subterranean environment.

Summary: Organic synthesis driven by solar energy is gaining attention for its advantages of selectivity and milder reaction conditions. However, the inefficient utilization efficiency due to slow charge separation limits its catalytic performance. Assembling 0D/2D Z-schemed semiconductor nano-heterojunctions can be a promising solution. In this study, 0D/2D carbon nitride quantum dots (CNQDs)/Bi2MoO6-x (BMO-OD) was synthesized, showing superior catalytic activity for amine oxidation coupling under ambient conditions. The design and synthesis of 0D/2D CNQDs/BMO-OD can enhance the photoinduced charge carriers' separation kinetics, promoting the photocatalytic oxidation coupling of amines under mild conditions.

Summary: Heavy metal pollution is a global environmental issue. In this study, a screen printed electrode modified with bismuth powder (Bi-SPE) was prepared for the detection of Cd2+. The Bi-SPE exhibited a linear detection range of 5-50 μg/L and a detection limit of 4.80 μg/L for Cd2+. Compared to the bare screen printed electrode, Bi-SPE showed better detection performance by providing more active sites for heavy metal ion predeposition. The advantage of Bi-SPE is its ability to detect heavy metal ions without the addition of bismuth ions in the solution, enabling in-situ detection. The prepared Bi-SPE holds great potential for the detection of heavy metal ions in real water samples.

Summary: This study reported a heterostructured Ni/Ni0.2Mo0.8N nanorod array electrocatalyst, which exhibited excellent electrocatalytic activity for the oxidation of 5-hydroxymethylfurfural (HMF) and achieved nearly 100% conversion of HMF and 98.5% yield of 2,5-furandicarboxylic acid (FDCA) products. Further experiments revealed that Ni species in the catalyst can be readily converted to NiOOH as the real active sites. In addition, a two-electrode electrolyzer assembled with this catalyst achieved simultaneous production of FDCA and H2 at a low voltage. This work highlights the significance of regulating redox activities of transition metals and constructing heterostructured electrocatalysts for more efficient energy utilization.

Summary: Numerous research studies have been conducted on lead-free glass frits for crystalline silicon solar cells due to the high toxicity of Pb. However, lead-free glass frits have poor metallization performance. In this study, a method for preparing low-content lead oxide composited glass frits was established to reduce PbO content while maintaining excellent properties. The addition of PbO improved the etching ability of the glass frit and resulted in increased conductive path when prepared into silver paste.

Summary: In this study, RuO2 electrocatalyst was defectively engineered to enhance the cooperation between NOR and OER, leading to efficient synthesis of nitric acid. The optimized D-RuO2 exhibited outstanding NOR activity in acidic electrolyte, with a maximum yield of 767.92 mu g h(-1) mg(cat)(-1), surpassing previous reports. Experimental and computational results indicated that OER intermediates played a crucial role, and the rate-determining step during nitrogen oxidation was the transition from *O to *OOH involved in the formation of *NN(OH). The enhanced stabilization of *OH and the promotion of O-O bond breakage in the rate determining step of *NN(OH) formation contributed to the excellent NOR activity.

Summary: Simultaneous water purification of multiple hazardous pollutants assisted by photocatalysis technology is an environmentally friendly and energy-smart strategy. In this study, a Z-scheme heterojunction of TiO2-Au@CN nanofibers was constructed, which showed excellent photocatalytic performance for inactivation of E.coli and removal of RhB under simulated solar light irradiation. The promoted photocatalytic performance was attributed to the Z-scheme electron transfer mechanism at the interface of the heterojunction assisted by AuNPs as an electron mediator. The constructed Z-scheme heterojunction with efficient light utilization showed great potential in practical water purification under sunlight.
