Summary: The measurement of Pb-204-based isotopic ratios by quadrupole ICP-MS was investigated and optimized. The internal precision of the isotopic ratios reached about 0.4% at a Pb concentration of 1 μg L-1 and about 0.2% at 10 μg L-1, similar to the values reported for major isotopes measurements. The developed method was demonstrated to be applicable in the environmental field and produced data in good agreement with the isotopic composition of airborne particulate in central Greenland.

Summary: A novel method called inductively coupled plasma (ICP)-assisted cutting was developed for sub-nanometer finishing of polycrystalline tin, reducing the influence of grain boundaries on surface roughness. The plasma-assisted cutting method achieved a surface finish from 8.53 nm to 0.80 nm in Sa for polycrystalline tin. Additionally, the residual stress of plasma-assisted turning processing was significantly lower compared to traditional turning process.

Summary: By using an inductive nonthermal plasma reactor fed with aluminum trichloride and Ar, single-crystal aluminum nanoparticles were synthesized with different reactor conditions affecting properties like oxide shell thickness, particle mono-dispersity, and particle size. Large quantities of Ar relative to AlCl3, short residence times, and high pressures are needed to form 10-20 nm Al particles with low geometric standard deviations.

Summary: By combining ICP OES with a novel FIGA mode, a more sensitive determination of Hg was achieved. The proposed method showed a much higher analytical signal for Hg compared to conventional PN-ICP OES, resulting in a significantly improved detection limit (0.035 μg/L) and measurement precision (2.5%). It also offered a 4 times lower detection limit compared to CVG-ICP OES (0.15 μg/L).

Summary: The electron density distribution of inductively coupled plasma (ICP) was measured using laser Thomson scattering (TS) method and simulated using finite element method (FEM). The accuracy of the ICP generation simulation model was verified by comparing the simulated and experimental results. The propagation characteristics of terahertz wave in ICP were measured using terahertz time domain spectroscopy (THz-TDS) and calculated using FEM, showing high consistency between experimental and simulation results. This further proves the accuracy of the terahertz wave transmission model in plasma and the feasibility of joint simulation with ICP generation simulation model.

Summary: This study reports the Cl-based inductively coupled plasma etching of N-polar Al(Ga)N layers and its effects on the surface quality. The results show that debris appeared on the etched N-polar surface, while the etched Al-/Ga-polar surface remained clean and smooth. Chemical analysis suggests that the debris is the result of Cl-related byproducts generated during the etching process. The formation and disappearance of debris are attributed to the formation of Al(Ga)Cl-x byproducts.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
