A double‐pulsed laser ablation (DPLA) method has been used to synthesize crystalline boron nanorods (BNRs), boron nanowires (BNWs), and bamboo‐like boron nanotubes (BBNTs) from bulk boron (BKB). A q‐switched Nd: YAG laser operating at the first and second harmonic wavelengths with 1064 and 532 nm is used to ablate a solid composite boron target doped with 1% Ni and 1% Co in a tube furnace in flowing argon gas. Boron nanostructures in the form of BNRs, BNWs, and BBNTs are condensed from the hot laser‐induced plasma plume at furnace temperatures of 800, 900, and 1000 °C. The morphology and the chemical and optical nature of the nanostructures are identified from X‐ray diffraction, electron microscopy, energy‐dispersive X‐ray spectroscopy, Raman, UV–vis, and photoluminescence (PL) spectroscopies. The results confirm the crystallinity and phase purity of the boron‐nanomaterials and that they are preferentially grown in the c‐axis direction of α‐boron. The as‐synthesized BNRs, BNWs, and BBNTs are observed to have lengths of 0.2–1.5 μm and widths between 10 and 100 nm, and show respective PL resonance emission peaks at 330, 331, and 333 nm, and the electrical conductivities of 312, 313, and 324 S cm−1 at room temperature which are higher than the electrical conductivity of BKB.

The formation, characterization, and dye sensitized solar cell application of nickel(II), zinc(II) and cadmium(II) ferrocenyl dithiophosphonate complexes were investigated. The multidentate monoanionic ligand [S2PFc(OH)]− (L1) was synthesized. The reaction between metal salt precursors and L1 produced Ni(II) complexes of the type [Ni{S2P(Fc)(OH)}2] (1) (molar ratio 1:2), and a tetranickel(II) complex of the type [Ni2{S2OP(Fc)}2]2 (2) (molar ratio (1:1). It also produced a Zn(II) complex [Zn{S2P(Fc)(OH)}2]2 (3), and a Cd(II) complex [Cd{S2P(Fc)(OH)}2]2 (4). Complexes 1–4 were characterized by 1H and 31P NMR, FTIR and elemental analysis, and complexes 1 and 2 were additionally analyzed by X‐ray crystallography. The first examples of dye‐sensitized solar cells (DSSCs) co‐sensitized with ferrocenyl dithiophosphonate complexes 1–4 are reported. Co‐sensitization with the ruthenium dye N719, produced the dye materials (3)‐N719 (η=8.30%) and (4)‐N719 (η=7.78%), and they were found to have a better overall conversion efficiency than the pure Ru N719 dye standard (η=7.14%) under the same experimental conditions. The DSSCs were characterized using UV/vis, cyclic voltammetry, electrochemical impedance spectroscopy (EIS), photovoltaic‐ (I−V curves), and performing incident photon‐to‐current efficiency (IPCE) measurements.

The manaksite mineral KNaMnSi 4 O 10 was synthesized and used to fabricate electrodes, which were investigated for electrochemical energy storage (EES) application using cyclic voltammetry (CV), galvanostatic charge and discharge (GCD), and electrochemical impedance spectroscopy (EIS). Optimum weight percentages (wt%) of electrode components were established as 10 wt% polytetrafluoroethylene (PTFE) binder, 15 wt% RuO 2 and 5 wt% carbon black. RuO 2 was added to improve electrical conductivity. A ratio of 13 : 3 for KNaMnSi 4 O 10  : RuO 2 was used in the fabrication of the electrode. A study of the suitable electrolyte and corresponding concentration to use was done using NaOH and KOH, both at concentrations of 1 M, 3 M and 6 M, with 3 M NaOH as the optimum electrolyte and concentration. The KNaMnSi 4 O 10 yielded a specific capacity of 106 mA h g -1 . An investigation into the energy storage mechanism from a plot of log  I ( ν ) vs. log  ν , where I is current and ν is the scan rate gave a b value parameter of 0.8; that is, in-between 0.5 obtained for a pure battery material and 1.0 for a pure capacitor material. Accordingly, KNaMnSi 4 O 10 exhibited a battery-supercapacitor duality phenomenon consistent with supercapattery materials. The KNaMnSi 4 O 10 electrochemical system involved both capacitive and diffusion-controlled processes and was found to have good cyclic stability. It is concluded that KNaMnSi 4 O 10 is a potential electrochemical energy storage material., Competing Interests: The authors declare no conflict of interest., (This journal is © The Royal Society of Chemistry.)

The first 8-electron Pd/Ag superatomic alloys with an interstitial hydride [PdHAg 19 (dtp) 12 ] (dtp=S 2 P(O i Pr) 2 - ) 1 and [PdHAg 20 (dtp) 12 ] + 2 are reported. The targeted addition of a single Ag atom to 1 is achieved by the reaction of one equivalent of trifluoroacetic acid, resulting in the formation of 2 in 55 % yield. Further modification of the shell results in the formation of [PdAg 21 (dtp) 12 ] + 3 via an internal redox reaction, with the system retaining an 8-electron superatomic configuration. The interstitial hydride in 1 and 2 contributes its 1s 1 electron to the superatomic electron count and occupies a PdAg 3 tetrahedron. The distributions of isomers corresponding to different dispositions of the outer capping Ag atoms are investigated by multinuclear VT NMR spectroscopy. The emissive state of 3 has a lifetime of 200 μs (λ ex =448; λ em =842), while 1 and 2 are non-emissive. The catalytic reduction of 4-nitrophenol is demonstrated with 1-3 at room temperature., (© 2023 Wiley-VCH GmbH.)
