Because of its useful optoelectronic properties and the relative abundance of its elements, the quaternary semiconductor Cu 2 ZnSnS 4 (CZTS) has garnered considerable interest in recent years. In this work, we dope divalent, high spin transition metal ions (M 2+ = Mn 2+ , Co 2+ , Ni 2+ ) into the tetrahedral Zn 2+ sites of wurtzite CZTS nanorods. The resulting Cu 2 M x Zn 1−x SnS 4 (CMTS) nanocrystals retain the hexagonal crystalline structure, elongated morphology, and broad visible light absorption profile of the undoped CZTS nanorods. Electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), and infrared (IR) spectroscopy help corroborate the composition and local ion environment of the doped nanocrystals. EPR shows that, similarly to Mn x Cd 1−x Se, washing Cu 2 Mn x Zn 1−x SnS 4 nanocrystals with trioctylphosphine oxide (TOPO) is an efficient way to remove excess Mn 2+ ions from the particle surface. XPS and IR of as-isolated and thiol-washed samples show that, in contrast to binary chalcogenides, Cu 2 Mn x Zn 1−x SnS 4 nanocrystals aggregate not through dichalcogenide bonds, but through excess metal ions cross-linking the sulfur-rich surfaces of neighboring particles. Our results may help in expanding the synthetic applicability of CZTS and CMTS materials beyond photovoltaics and into the fields of spintronics and magnetic data storage.

“…Chemical reduction is popular due to its relative simplicity and low cost [9]. Selective plating can be obtained using a local chemical reduction method [12], whereas optical reduction allows for selective activation and direct metallisation of the surface, without the use of costly additional processing [13].…”

This article reports the performance of different metallic ions and nanoparticles (Ag, Cu, Ni, Pd, Cr, Co, Au and Fe) used as seed layers, formed by chemical or optical reduction, for the electroless Cu plating of metal tracks onto polyetherimide (PEI). Plated Cu performance was tested by adhesion, electrical conductivity, plating rate, XPS, SEM, XRD and EDX analysis. The application of Cu and Ag seeds resulted in high quality electroless Cu deposits presenting strong adhesion properties and high conductivity ((2.0 ± 0.5) ×10 7 S/m and (3.6 ± 0.2) ×10 7 S/m, respectively) compared with bulk copper (5.96 ×10 7 S/m). Performance is attributed to the high surface density and uniformity of seed layers. Of the metals, only Ag ions were photoreduced under the conditions applied and were subsequently used to electroless Cu plate high quality track features of 150 µm width. The application of sulphuric acid pre-treatment to PEI prior to Ag ion exchange, improved the photoinitiated track formation process, as demonstrated by a threefold increase to both photoinduced Ag nanoparticle density on the surface and electroless Cu plating rate, as well as improved electroless Cu adhesion to PEI.

Thermal Extraction of Polycyclic Aromatic Hydrocarbons from Atmospheric 2.5 μm Particulate Matter Collected on a Filter Paper Using a High-Temperature Headspace Method

Recently, owing to the performance improvement of the headspace (HS)-sampling devices and its consumables, HS vial samples can be analyzed at temperatures up to 300°C. Some studies have attempted to analyze polycyclic aromatic hydrocarbons (PAHs) in atmospheric 2.5 µm particulate matter (PM 2.5) collected on filter paper by gas chromatography/mass spectrometry (GC/MS) coupled with thermal desorption device. However, no studies have reported the use of an HS-sampling device to quantify PAHs in PM 2.5 filter paper. In this study, we found that the quantification of PAH analysis using HS-GC/MS can be improved by the following steps, so that the accuracy becomes almost the same as that of a solvent-extraction method: 1) replacement of the air in the HS vial with nitrogen, 2) limiting the solvent to toluene, 3) using hydrolyzed polyimide-covered septum, and 4) optimization of the heating temperature and heating time of the HS vial.As a result, we succeeded in protecting PAHs in an HS vial at a high temperature and in creating an analysis method with a high recovery rate and high repeatability; the limit of quantitation of each PAH in this method was 5.4 pg m −3 in the case of a volume of 10,080 m 3 of air being collected on the filter paper.
