Conformal printing of electrically small antennas onto the convex and concave surfaces hemispherical glass substrates is demonstrated. Their bandwidth approaches fundamental limit for their size, offering nearly an order magnitude improvement over rudimentary monopole designs. Detailed facts importance to specialist readers are published as ”Supporting Information”. Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted by authors.

Solid-state electrolyte separators play a critical role in improving energy density, charging rate, and safety next-generation batteries; however, controlling the interface between Li-metal separator continues to be challenging. Here, using garnet-type Li7La3Zr2O12 (LLZO) ceramic solid electrolyte, we show that sputter-coated thin metallic interlayers (∼300 nm of gold) combination with controlled discharge rates (0.3 mA/cm2) practical levels external pressure (0.7 MPa) vital roles mitigating...
Lithium–metal batteries with solid electrolyte separators promise improvements in energy density, fast charge capability, and safety. However, the lack of control electrolyte–lithium–metal interface continues to impede development. Interlayers between lithium–metal are reported improve performance but have limitations due stability, rate limitations, use undesirable elements (e.g., Ag, Au). Here, we show that a thin layer abundant metal Sn provides required stability transport properties...
Vinylene carbonate (VC) and polyethylene oxide (PEO) have been investigated as functional agents that mimic the solid electrolyte interphase (SEI) chemistry of silicon (Si). VC PEO are known to contribute stability Si-based lithium-ion batteries an additive a SEI component, respectively. In this work, covalent surface functionalization was achieved via facile route, which involves ball-milling Si particles with sacrificial PEO. Thermogravimetric analysis (TGA), X-ray photoelectron...
Printed electronics rely on low-cost, large-area fabrication routes to create flexible or multidimensional electronic, optoelectronic, and biomedical devices1-3. In this paper, we focus one- (1D), two- (2D), three-dimensional (3D) printing of conductive metallic inks in the form flexible, stretchable, spanning microelectrodes. Direct-write assembly4,5 is a 1-to-3D technique that enables features ranging from simple lines complex structures by deposition concentrated through fine nozzles...
Abstract Cation‐disordered rocksalt (DRX) cathodes have recently emerged as a promising class of cobalt‐free, high‐capacity for lithium‐ion batteries. To facilitate their commercialization, the development scalable synthesis techniques providing control over composition and morphology is critical. this end, sol‐gel route to prepare Mn‐rich DRX with high capacities presented here. Several compositions varied Mn content nominal F doping are successfully prepared using technique. In‐situ X‐ray...
The design tradeoffs between three spherically conformal electric monopoles-the spherical helix (SH), meanderline (SM), and a hybrid design-are explored through both simulation measurement. We show that the SH is efficient, but can be difficult to impedance match without external components. On other hand, SM antenna has widely controllable with slightly increased loss. Thus, proposed retains desirable qualities of SM. All designs are fabricated using printing technique for comparison....
In this work, we modified the reaction pathway to quickly (minutes) incorporate lithium and stabilize ionic conducting garnet phase by decoupling formation of a La–Zr–O network from addition lithium. To do this, synthesized La2Zr2O7 (LZO) nanoparticles which LiNO3 was added. This method is departure typical solid-state synthesis methods that require high-energy milling promote mixing intimate particle–particle contact sol–gel syntheses as unique porous microstructure obtained. We show time...

The performance of single-ion conductors is highly sensitive to the material's defect chemistry. Tuning these defects limited for solid-state reactions as they occur at particle–particle interfaces, which provide a complex evolving energy landscape atomic rearrangement and product formation.

Consumer safety is a market force that impeding high energy-dense lithium metal batteries from entering the marketplace. As such, research and development into solid electrolytes (SE) have yielded several promising candidates for solid-state batteries. However, each class of SEs comes with particular problems either increase processing cost, or decrease performance relative to current liquid electrolytes, both. For example, Lipon other similar silicates phosphates are stable against voltage...
Silicon (Si)-based negative electrodes often have these two prerequisites for improved performance: submicron or nanoscale dimension and additives (generally electrolytes). In this work, a single approach was implemented to achieve the beneficial effects of both. Functionalized Si particles with an average diameter less than 300 nm good polydispersity indices (0.2 0.3) were successfully generated by ball-milling vinylene carbonate (VC) polyethylene oxide (PEO). Surface characterization using...
