“…Very high defect site densities in 3D-NSCAs are shown by a Raman spectrum with an intensity ratio of the D and G bands ( I D / I G ) of 3.4 (Figure G and Table S1). This may result in accelerated electron transport, which is necessary for excellent sensing performance. , X-ray photoelectron spectroscopy (XPS) spectrum (Figure S15) suggests that 3D-NSCAs contain the element N, which is crucial for enhancing their electrocatalytic performance. − The functional groups containing oxygen in 3D-NSCAs, as shown by the XPS and Fourier transform infrared (FT-IR) spectra (Figures S15 and S16), are very advantageous for lowing charge transfer resistance and improving the hydrophilicity of the electrode interface . In light of the aforementioned, 3D-NSCAs emerge as promising nanoscaled material for manufacturing UA sensor.…”

Fully integrated wearable sensors are capable of dynamically, directly, and independently tracking biomarkers in raw noninvasive biofluids without any other equipment or accessories by integrating the unique on-body monitoring feature with the special complete functional implementation attribute. Sweat, saliva, and urine are three important noninvasive biofluids, and changes in their biomarkers hold great potential for revealing physiological conditions. However, it is still a challenge to design single fully integrated wearable sensor arrays (FIWSAs) that are universally able to concurrently measure electrolytes and metabolites in three of the most common noninvasive biofluids including sweat, saliva, and urine. Here, we propose the first single universal FIWSAs for wirelessly, noninvasively, and simultaneously measuring various metabolites (i.e., uric acid) and electrolytes (i.e., Na + and H + ) in raw sweat, saliva, or urine under subjects' exercise by integrating the specifically designed microfluidic, sensing, and electronic modules in a seamless manner. We evaluate its utility for noninvasive gout management in healthy subjects and in gout patients through a purine-rich meal challenge and with a medicine-treatment control, respectively. Noninvasive monitoring of multiple electrolytes and metabolites in a variety of raw noninvasive biofluids via such single universal FIWSAs may enrich the understanding of the biomarkers' levels in the body and would also facilitate self-health management.

“…45 Inductively coupled plasma optical emission spectrometry (ICP-OES) and elemental mapping results showed that the Ru loading in Ru 1 /NiO was 0.17 wt % with Ru species uniformly dispersed on NiO support. Apart from that, SACs such as Co 1 /SNC, 46 Ce 1 /NC, 47 Pt 1 @Co, 48 etc., could also be prepared using this method. The convenience of this method lies in the free use of templates, additives, or solvents, which greatly simplifies the synthetic process.…”

Among all renewable energy sources (e.g., solar energy, wind, and biomass), biomass is the only organic carbon resource which has great potential to partly replace nonrenewable fossil resources to produce high value-added chemicals and biofuels. Singleatom catalysts (SACs) have shown compelling prospects and arguably become one of the most active research fields in biomass chemical catalysis due to their fascinating strengths in maximum atomic utilization, highly efficient catalytic reactivity, high selectivity, and good stability. Numerous achievements about the SACs have recently been amassed, including advanced synthesis methods, characterization techniques, and theoretical calculation, allowing us to forecast their working mechanisms and the catalytic roles of metals and coordination sites in the catalytic process. Based on the relevant literatures on SACs over the past few years, this review summarizes the preparation methods of SACs and their catalysis applications for biomass conversions with a special focus on the structure−activity relationship and catalytic reaction mechanism as well as prospects for the future developments of SACs. This review provides fundamental information for the development of the SACs in biomass valorization, clearly stimulating the development in this emerging research field.

“…Ball milling method, a top-down mechanochemical route, refers to putting one or mixed metal salts into a ball mill, adding ball milling beads for milling for a period of time to obtain atomic-scale metal balls, which interact with the carriers to form SACs. 90,91 The advantages of this method are no templates, solvents, or additives, and are easy to scale up and expand, which has the potential for largescale production. Ji et al 92 successfully prepared 60, 200, and 1000 g noble metal SACs by ball milling with large ball mills and more feed quantities, and the catalyst structure remained unchanged (Figure 12).…”

In recent years, owing to the depletion of fossil energy and the aggravation of environmental pollution, the conversion and storage of distributed renewable energy (such as solar energy, wind energy, and tidal energy) based on electrochemical technology have attracted extensive attention. Electrocatalytic processes with high efficiency and high selectivity play a key role in clean energy conversion and storage. With the nearly 100% atomic utilization rate and unique catalytic activity, single-atom catalysts (SACs) have been rapidly developed and widely used in the field of energy conversion and storage. In this review, we first introduce the characteristics of SACs. Then, we focus on the application of SACs in energy conversion, including water electrolysis reaction, nitrogen reduction reaction, nitrate reduction reaction, oxygen reduction reaction, and carbon dioxide reduction reaction. In terms of energy storage, we focus on supercapacitors and Li-S batteries. Further, we enumerate some of the methods for the synthesis of SACs in high metal loading or large scale. Finally, the main challenges and opportunities for this emerging field in the future are discussed and prospected.
