Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Electromagnetic wave absorption materials require high dielectric loss and excellent impedance matching performance. However, current conventional biomass‐derived electromagnetic wave absorption materials are still limited by low electrical conductivity and a single structure.

, 2019 在低碳经济下,以由低碳制造商、普通制造商和零售商组成的供应链作为研究对象,考虑了无碳税和有碳税两种情形,分析了分散决策和集中决策两种情况下供应链减排决策及合作策略,研究发现,在分散决策的情况下,碳税税率应该设置在一个合理分范围内,这样才能够充分调动低碳制造商减排的积极性,碳税如果设置过高,增加了企业的经营负担,并没有起到减排的作用,但是在集中决策下,碳税越高越能促进企业减排;同时还发现集中决策能够有效地提高供应链利润,因此需要设计一定约束机制来保证供应链各企业能够按照集中决策的方式来进行决策 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of structurally stable anodes with high capacities and long cycle lives is essential for the development of potassium–ion batteries. Conversion‐type anodes have attracted considerable attention in potassium–ion batteries (PIBs) due to their high theoretical capacities.

, 2023 作为算力承接地，西部地区拥有丰厚的自然资源禀赋，需充分发挥其在能源、气候等方面的优势。“东数西算”背景下，数据中心急需对算力转移过程的碳减排效益进行量化分析。在考虑可再生能源、气候因素和传输过程3个影响因素的情况下，构建了数据中心工作负载转移的碳排放量核算模型，以“东数西算”八大节点为例进行算例分析。结果发现，相较于可再生能源和气候因素所减少的碳排放量，传输过程造成的额外碳排放量微乎其微，在仅考虑前两者的情况下，每转移1 kW·h的工作负载，碳排放量可减少0.053~0.344 kg ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Size‐controllable Sn nanoparticles are designed in this work via oxide doping to be uniformly embedded into flexible N‐doped carbon nanofibers, in which the agglomeration and migration of Sn are effectively restrained due to the suppressive effect of selected oxides, including SiO2, TiO2, and ZnO. Benefiting from unique merits of the embedment

, 2008 由 CO_2大量排放所引发的温室效应,已经成为全球普遍关注的环境问题之一。如何从源头减少二氧化碳排放和降低大气中二氧化碳的含量成为挑战人类智慧的难题。但从资源化角度出发,CO_2 是一种安全丰富的碳资源,具有多种用途,因此从工业废气中捕集、回收 CO_2即可以降低大气中二氧化碳的含量,达到减排目的,又可以有效利用碳资源,减少经济损失。现有的 CO_2捕集技术包括生物法、物理法和化学法等,但这些方法都具有一定的局限性,如碳资源的浪费及有机溶剂的挥发进一步导致环境污染、设备腐蚀、后处理复杂等问题 ...

Gongye shui chuli日趋严格的排放标准在提升治污效能的同时，也导致能耗与碳排增加，呈现“水质提升而碳排加剧”的突出矛盾。在“双碳”战略与水污染防治协同推进的背景下，污水处理厂作为能耗与碳排放的关键节点，其减污降碳协同治理已成为行业绿色转型的核心议题。本文梳理了其在污染削减、碳排放核算、协同路径及评价体系等方面的研究进展，揭示了污染控制与碳减排间的内在耦合关系。污水处理过程的碳排主要来自生物处理与污泥处置单元，由直接排放（CO₂、CH₄、N₂O）与间接排放（能源、药剂）共同构成。为实现协同增效，提出以“数字化+绿色技术 ...
