Advanced Functional Materials, EarlyView.Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Defect Analysis of the β– to γ–Ga2O3 Phase Transition
Advanced Functional Materials, EarlyView.The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1972 In the United States of America the natural gas which contains about 0.4% up helium content is used as main material for producing the helium gas. The equipment recently developed in France separates and rectifies 0.05% of helium gas to produce high purity of helium gas.

Modulating Electrochemical CO2 Reduction Pathways via Interfacial Electric Field
Advanced Functional Materials, EarlyView.Engineering interfacial electric fields in Cu/ITO electrodes enables precise control of CO2 reduction pathways. Charge transfer from Cu to ITO generates positively charged Cu species that steer selectivity from ethylene toward methane. This work demonstrates how interfacial electric‐field modulation can direct reaction intermediates and transform ...

Delayed annihilation of antiprotons in helium gas [PDF]
Physical Review A, 1994 The delayed annihilation of antiprotons, which was recently discovered in liquid $^{4}\mathrm{He}$ at KEK, has been studied at CERN in gas-phase $^{4}\mathrm{He}$ and $^{3}\mathrm{He}$. The annihilation time spectra in gaseous $^{4}\mathrm{He}$ at various pressures were found to be similar to that for liquid $^{4}\mathrm{He}$.

Advanced Functional Materials, EarlyView.While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...
