Photocatalytic conversion of lignocellulose to valuable aromatics has significant potential for applications in biorefineries. The photocatalyst efficiency is typically limited by the buffering redox system combination with oxidation and reduction photoexcited holes electrons, respectively, which ensures high charge-recombination rates. Herein, Ag+-exchanged CdS employed easy electron transfer oxidized intermediate, results a marked increase yield product selectivity under mild reaction...
Abstract Thermoelectric power generation offers a promising way to recover waste heat. The geometrical design of thermoelectric legs in modules is important ensure sustainable but cannot be easily achieved by traditional fabrication processes. Herein, we propose the cellular architectures for efficient and durable generation, realized extrusion-based 3D printing process Cu 2 Se materials. We optimum aspect ratio cuboid leg maximize output extend this mechanically stiff hollow hexagonal...
Abstract Compared with the large plastic deformation observed in ductile metals and organic materials, inorganic semiconductors have limited plasticity (<0.2%) due to their intrinsic bonding characters, restricting widespread applications stretchable electronics. Herein, solution‐processed synthesis of α‐Ag 2 S thin films fabrication all‐inorganic, self‐powered, memory devices, is reported. Molecular Ag complex solution synthesized by chemical reduction powder, fabricating wafer‐scale...
The recent interest in wearable electronics suggests flexible thermoelectrics as candidates for the power supply. Herein, we report a solution process to fabricate Sb2Te3 thermoelectric thin films using molecular precursors, synthesized by reduction of powder ethylenediamine and ethanedithiol with superhydride. fabricated exhibit factor ∼8.5 μW cm–1 K−2 at 423 K, maintaining properties during 1000 bending cycles. FePt nanoparticles are homogeneously embedded film, reducing thermal...
Cation-exchange-induced phase transformations have recently been employed for the synthesis of a variety nanomaterials. In this study, we induced cation-exchange reaction by adding Bi-oleate to PbS quantum dots (QDs) and synthesized uniform Pb1–xBixSy QDs nanorods (NRs) with diameter approximately 3 nm length 40 (aspect ratio 1:5), respectively. Colloidal are promising materials thermoelectric applications owing their simple production process, easy dimensional control, low thermal...
Abstract Graph Neural Networks (GNNs) exhibit potential in predicting the properties of molecules, but computational analyses with GNNs often encounter problem data imbalance or overfitting. Augmentation techniques have emerged as a popular solution, and adversarial perturbation to node features achieves significant improvement enhancing model's generalization capacity. Despite remarkable advancement, there is scarce research about systematically tuning augmentation. We propose new framework...

정치자금의 문제는 정치영역에서의 문제이고 정치적 공동체 내에서의 국민의 자유권과 밀접한 관계를 갖는다. 그리고 이 법에 의해 특별히 그 인격이 부여된 법인이나 단체도 존재성에 기하여 어떠한 의미에서는 자유권을 향유할 수 있는 주체가 될 있다는 점에서 기업을 대표로 하는 법인과도 관련된 문제이다. 다만 기업의 정치자금 기부 허용의 특히 자본력에 있어서 개인을 능가하는 단체와의 힘의 불균형을 조정해야 할 필요성이 있을 뿐만 아니라 이러한 방치하는 경우에는 자연인인 개인들의 주권자로서의 지위가 약화되는 지경에 이르게 된다는 규제의 당위성은 인정된다. 또한 정경유착의 부패적 경험과 이에 대한 우려가 심각한 선거현실 속에서 더군다나 막강한 자본력을 보유한 기업인 더 신중한 검토와 고민이 함께 해야만 것이다. 문제의식을 바탕으로 하여 글에서는 규제에 관한 전면적 금지규정에 검토를 주된 분석대상으로 하고 있다. 기업이 헌법상 자유권의 기본권주체성을 갖는 것인지, 영역에서 기본권능력을...
Abstract Thermoelectric (TE) power generation offers a promising way to recover waste heat. The geometrical design of TE legs in modules is important ensure sustainable but cannot be easily achieved by traditional fabrication processes. Herein, we propose the cellular architectures for efficient and durable generation, realized extrusion-based 3D printing process Cu 2 Se materials. We designed optimum aspect ratio cuboid leg maximize output extended this mechanically stiff hollow hexagonal...
