Dual-Band Microwave Sensor Based on Planar Rectangular Cavity Loaded With Pairs of Improved Resonator for Differential Sensing Applications

IEEE Transactions on Instrumentation and Measurement, 2021
A dual-band sensor based on a planar rectangular cavity loaded with pairs of improved planar resonator is used to measure the permittivity difference of liquids with a small volume ( $2.5~\mu \text{l}$ ).

Superconductivity in a quintuple-layer square-planar nickelate

Nature Materials, 2021
Since the discovery of high-temperature superconductivity in copper oxide materials1, there have been sustained efforts to both understand the origins of this phase and discover new cuprate-like superconducting materials2.

Planar and non-planar borepins

Molecular Physics, 1996
Theoretical studies of borepin and its B-substituted derivatives show planar structures with weak out-of-plane bending modes, often leading to boat-shaped borepins. The lowest vibrational frequency of borepin is 167 cm-1 at both HF/6-31G* and MP2/6-31G* levels, compared to 248 cm-1 calculated for the isoelectronic tropylium ion.

Formamidinium lead trihalide: a broadly tunable perovskite for efficient planar heterojunction solar cells

, 2014
Perovskite-based solar cells have attracted significant recent interest, with power conversion efficiencies in excess of 15% already superceding a number of established thin-film solar cell technologies.

Lattices contained in planar orders are planar

Algebra Universalis, 1992
The following is the main result of the paper. Let \(P\) be a finite ordered set with planar covering graph and let \(\text{cov}(P)\) be its planar representation. Let \(L\) be a truncated lattice contained in \(P\). Then the covering graph of \(L\) has a representation \(\text{cov}(L)\) in which, whenever \(b\) covers \(a\) in \(L\), the edge joining \

Planar heterojunction perovskite solar cells via vapor-assisted solution process.

Journal of the American Chemical Society, 2014
Hybrid organic/inorganic perovskites (e.g., CH3NH3PbI3) as light absorbers are promising players in the field of third-generation photovoltaics. Here we demonstrate a low-temperature vapor-assisted solution process to construct polycrystalline perovskite

Methylammonium-free, high-performance, and stable perovskite solar cells on a planar architecture

Science, 2018
Staying in the black phase Hybrid perovskite solar cells often use the more thermally stable formamidinium (FA) cation rather than methylammonium, but its larger size can create lattice distortion that results in an inactive yellow phase.

PLANAR LACES

Journal of Knot Theory and Its Ramifications, 2002
Let S be a connected open subset of 2-sphere S2 which is identified with the extended plane R2 ∪ {∞}. We assume that S contains the n segments {1, 2, …, n} × [-1, 1]. An n-lace ℓ (in S) is the union ℓ1 ∪ … ∪ ℓn of disjoint simple arcs in S such that ∂ ℓi = {(i, 1), (π (i),-1)}, i = 1, …, n, for some permutation π of {1, 2, …, n}.
