Abnormal Grain Growth: A Spontaneous Activation of Competing Grain Rotation

Abnormal Grain Growth: A Spontaneous Activation of Competing Grain Rotation
放射光白色X線を利用したラウエ回折測定によって、微粒子からなるロール加工後のマグネシウム合金の加熱過程のその場観察を行った。高温下では単結晶粒からの回折点が母合金粒子からのリングに重なって観察された。いくつかの粒子からの反射が自発的に動く様子が観察され、粒界に発生すると予想されるトルクによって粒子の回転が引き起こされていることが示唆された。この回転が起きると拡散による輸送が可能となり、粒子に近接する粒界が活性化する。次に粒子が自由に回転し粒成長しようとするが、多数の粒界のトルクの方向と大きさが競合しジグザグ状回転となる。粒成長後、粗大化した結晶粒は引き続き活性化しており、大半の母合金粒子が不活性となるまで上記の過程を繰り返す。本結果は異常粒成長を引き起こすメカニズム解明に必要な知見を与えるものである。

Soybean increases grain Zn and protein of winter wheat grown in the three-crop rotation

Crop rotation systems provide various benefits to sustainable agriculture. The inclusion of legume crops in rotation enhances the nutrient cycle in the soil-plant system, and especially the nitrogen (N) nutritional status of wheat.

Enhanced Stability in Zero‐Excess Li‐Metal Batteries via Prelithiated Carbon Nanofiber Interlayers

Advanced Science, EarlyView.
Carbon nanofibers carbonized at 700°C show Li metal deposition predominantly on the side facing the Cu current collector. During delithiation, Li agglomerates remain as inactive lithium on the fiber surface. This behavior can be changed by a modified n‐Buli prelithiation without a washing step, suppressing dead Li formation and therefore enabling ...

An Embodied Paper‐Based Microfluidic Al‐Air Battery for Enduring Untethered Insect‐Scale Robots

Advanced Science, EarlyView.
This work presents a centimeter‐scale microfluidic aluminum–air battery (MFAAB) with dual‐surface anode and F−‐mediated byproduct decomposition. The design enables a high capacity of 2697.05 mAh/g Al and delivers tens of milliwatts to power LEDs, motors, and a toy car.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
