Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

Advanced Functional Materials, EarlyView.
CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

The Structure of Crystalline Polyacetylene

The Journal of the Society of Chemical Industry, Japan, 1962
チーグラー型の触媒を用いて合成したアセチレン重合体は,典型的有機半導体として挙動し,非局在性の不対電子をもち,長い共役二重結合系からなる重合体であると推測されたが,この重合体の構造やその共役系の長さについてより詳しく調べるために,赤外吸収スペクトル,X線回折図および比抵抗などを測定し,常磁性共鳴吸収の結果とあわせて,これらアセチレン重合体の構造に関し推論を試みた。アセチレン-d2より合成されたポリ(アセチレン-d2)とアセチレン重合体の赤外吸収スペクトルを観測し,それらの各バンドを比較し,各バンドの帰属を行なった。その結果,このアセチレン重合体は対称性の大きいトランス・トランス型共役二重結合からなる平面ジグザグ構造であることを証明した。X線回折図によれば,重合体分子面相互の間隔は3 ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
