Summary: The bi-functional activities of electrocatalysts for the ORR and discharge products decomposition in rechargeable Li-O2 batteries can be effectively evaluated using cyclic voltammetry with varying the lower potential limit. Utilizing Ru-Sn oxides decorated graphene nanowalls as examples, it was found that both Ru-enriched and Sn-enriched Ru-Sn oxides exhibit higher bi-functional activities than mono-oxides and pure graphene. The full cell performance in terms of rate capability, cycle life, and charge-discharge voltage gaps can be correlated to these findings.

Summary: Exploring and applying novel and sustainable deep eutectic solvents (DESs) for lignocellulose pretreatment is a promising approach for efficient bioconversion. However, the selection of efficient DESs and the inner mechanisms of lignocellulose deconstruction are still limited. In this study, bio-based acetylcholine chloride (AChCl) was used as a hydrogen bond acceptor with lactic acid, urea, and glycerol for microwave-assisted pretreatment of moso bamboo. The lactic acid-AChCl DES showed the highest enzymatic conversion yield of bamboo cellulose (-85%) due to its lower pH value and viscosity, followed by glycerol-AChCl and urea-AChCl DES. The chemical and physical properties of bamboo biomass after pretreatment were systematically determined, and it was found that the removal of lignin (-90%)/xylan (100%) and changes in cellulose structures played key roles in promoting bioconversion yields. The effects of novel DESs pretreatments on lignocellulose deconstruction were evaluated, which may provide new strategies for bioconversion enhancement and process optimization.

Summary: Communicable diseases spread quickly through infectious mediums among people and animals, such as bacteria and viruses. The recent global outbreak of COVID-19 has motivated researchers to use smart sensor technologies to detect, prevent, and control the spread of communicable diseases. Smart sensors, including biosensors, wearable sensors, unmanned vehicles, and bedsheet sensors, collect real-time data on the transmissibility of diseases, which can be processed using advanced machine-learning techniques. The use of smart sensors helps facilitate more accurate diagnoses of communicable disease viruses.

Summary: In this research, a nanostructured zinc oxide nanoparticle-modified carbon paste electrode (ZnO/CPE) was used along with an anionic surfactant and sodium dodecyl sulphate (SDS) to detect trimethoprim (TMP) through voltametric techniques. The electrode showed higher peak current than the original CPE. Various parameters such as pH, immersion time, scan rate, and concentration were studied. The TMP electrode process was found to be irreversible and diffusion controlled with two electrons transferred. The developed electrode proved effective in detecting TMP in pharmaceutical dosages and urine samples, indicating its potential in clinical and pharmaceutical sample analysis.
