Summary: Researchers have developed a new strategy to control the on-surface radical oligomerisations by using tunneling electrons, leading to the controlled synthesis of alkyl oligomers. This transfer only occurs under specific conditions, allowing for the precise formation of oligomers with defined size distribution.

Summary: This study reports the fabrication and characterization of titanium nitride nanobridge Josephson junctions and nanoscale superconducting quantum interference devices on SiN-buffered Si substrates. The use of titanium nitride allows for reproducible preparation and long-term stability of the devices. The variable thickness shape of the nanobridge junctions is achieved through wet etching and reactive ion etching. The results pave the way for superconducting electronics and all-TiN qubits operating at sub-100 mK temperatures.

Summary: Sigma-type and pi-type excited dipole-bound states (DBSs) were observed in cryogenically cooled potassium iodide (KI) anions for the first time. Experimental and theoretical results showed excellent agreement, confirming the prediction that a dipolar molecule with a large enough dipole moment can have an excited DBS.

Summary: In this study, positron-electron annihilation spectra of benzene, deuterated benzene, and naphthalene were theoretically calculated using Feshbach vibrational resonance energies and widths. It was found that the contribution of symmetric ring stretching vibration mode to the annihilation spectrum is significant and affects the p-electron density.

Summary: The Keldysh-Usadel technique (KUT) is necessary for describing non-equilibrium situations in a superconductor below its critical temperature, but it has not been applied to realistic circuits. To check the validity of this procedure, a toy model (the Ginzburg-Landau model) is used in situations with slow evolution. It is found that neglecting the explicit influence of time variation leads to inaccurate or even qualitatively wrong description of phase slips.

Summary: We have developed a self-biased planar 4-Josephson-junction nanoscale superconducting quantum interference device (nanoSQUID) with optimal sensitivity without the need for a magnetic flux. The nanoSQUID includes novel NbN-TiN-NbN nanobridge Josephson junctions (nJJs) with NbN current leads and TiN nanobridges connecting the electrodes of the nanoSQUID body. The nJJ and nanoSQUID exhibit hysteresis-free, reproducible, and long-term stable operation at 4.2 K, thanks to the optimal superconducting transition temperature and corrosion resistance of the TiN and NbN films. The nanoSQUID's cantilever is fabricated with a distance of approximately 300 nm between the nanoSQUID and the substrate corner, using amorphous Al films as sacrificial layers.

Summary: In this study, dissociative electron attachments of CO2- via the lowest shape resonant state (2)Pi(u) were investigated using a high-resolution anion velocity map imaging apparatus. The results showed that the dissociation of CO2-((2)Pi(u)) proceeds through a combinational motion of bond stretching and bending. This study provides important insights into the dissociation dynamics of CO2-((2)Pi(u)).

Summary: This study aimed to provide 5-year follow-up data comparing patient-reported outcomes for mandibular overdentures supported by two implants with magnetic attachments under immediate or conventional loading. Results showed no significant differences between the immediate loading group and the conventional loading group throughout the study. However, significant improvements in oral health-related quality of life, patient satisfaction, and denture assessment were observed within both groups from baseline to years 1-5.

Summary: The article investigates the fabrication and optimization of Rf SQUIDs on MgO substrate. Ion beam etching as a post fabrication trimming process is used for noise optimization, but it degrades the low frequency 1/f noise. It is found that similar noise performance can be achieved in SQUIDs without the need of trimming.

Summary: A facile polymer-directed metal-organic framework (MOF)-based nanoarchitechtonics was developed to enhance the catalytic efficiency of multi-enzyme cascade reactions through substrate channeling. The new method involved the simultaneous synthesis of MOF and co-immobilization of enzymes, resulting in a closely packed nanoarchitecture with enhanced substrate channeling. The enzyme cascade reaction system showed a 3.5-fold increase in catalytic activity compared to free enzymes.

Summary: An electrochemical biosensor based on rolling circle amplification (RCA) was developed for the detection of lead ion (Pb2+). The biosensor utilized Pb2+-dependent DNAzyme and DNA-templated silver nanoclusters (DNA-AgNCs) for amplification, and showed high sensitivity and selectivity for Pb2+ analysis in the range of 1 pM-10 μM with a detection limit of 0.3 pM. This strategy has potential applications in real water samples and environment analysis.

Summary: This study demonstrates that NbB2 nanoflakes exhibit excellent selectivity and durability in ambient electrochemical N-2 reduction reaction, leading to efficient NH3 production. The high selectivity is attributed to the presence of abundant active vacancies on the surface, which makes the N-N triple bonds in N-2 molecule easier to break for NH3 production.
