Completing Form NC-4 helps your employer determine how much to withhold from your paycheck for North Carolina’s flat-rate individual income tax. The number of allowances you claim on the form influences how much is withheld. The more allowances you claim, the less tax will be taken from your paycheck, increasing your take-home pay.

2022年4月6日 · Here, we report a bioinspired artificial ion channel by assembly of acidic MOF (MIL-53-COOH; MIL: Matériaux de l′Institut Lavoisier) into single polyethylene terephthalate NC (PET NC) to achieve ultrafast rectifying counter-directional transport of metal ion and proton.

2025年1月22日 · The synergistic effect of N-doped double nanocarbon encapsulation and multielectron reactions is employed to promote the optimized Na 3.25 VMn 0.25 Fe 0.75 (PO 4) 3 /NC@CNTs (NVMn 0.25 Fe 0.75 P/NC@CNTs) electrode material to deliver fast Na + diffusion kinetics, high reversible capacity (110.2 mAh g –1 at 0.1 C), and long-term cyclic ...

2024年4月30日 · 本文通过延长硬碳负极的老化时间，可以在其纳米孔中实现更充分的电解液预脱溶剂化，从而显著提升钠离子存储的效率和初始库仑效率。 这种策略不仅显著提高了硬碳负极的ICE，达到98.21%的平均值，而且没有牺牲电池的容量和循环稳定性。 此外，本文提出的双SEI模型有效地解释了硬碳负极中不可逆钠损失的机制，并展示了通过调控纳米孔中的脱溶剂化过程来优化电池性能的可能性。 这些发现为设计更实用的硬碳材料和推动其商业应用提供了重要的理 …

Several basin studies reported that iC 4 /nC 4 and iC 5 /nC 5 increase with increasing thermal maturity in oils and condensates (Connan and Cassou, 1980) and natural gases (Qin et al., 2019...

2025年3月26日 · 1 Introduction sodium-ion batteries (SIBs) are expected to be next-generation energy storage systems due to the advantages of abundant resources, lower cost, and environmental safety [1 - 4]. Anode materials have been widely studied as a key factor affecting the performance of SIBs [5 - 7].
