There's another compelling reason to bring back a cheaper MacBook: It's the perfect way to court disgruntled Windows users, something Apple hasn't really done since its "Get A Mac" ads from the mid-2000s. I figure the unbridled success of the iPhone and iPad made Apple focus less on directly competing with Windows. The sleek designs of the 2011-2015 era MacBook Air and Pros were their main selling points, but Apple's push towards USB-C-only machines and unreliable butterfly keyboards later made it clear it wasn't totally focused on Macs.
The Guardian reports that US Customs and Border Protection is already preparing a system to process refunds for affected companies, but that might not mark the end of Trump’s tariff regime. In a press conference held after the Supreme Court released its decision, the President announced plans to introduce tariffs using other, more constrained methods. Tariffs aren’t the only obstacle Nintendo faces, either. The company could also be forced to raise the price of its consoles in response to the current RAM shortage.,这一点在PDF资料中也有详细论述
2月25日,中国科学院等研究团队在《自然·能源》(Nature Energy)上发表论文Regulating grain growth via Li2SnS3 interphase in kesterite solar cells with certified efficiencies exceeding 15%,报告了一种新型铜锌锡硫硒太阳能电池,可实现超过15%的光电转换效率。研究团队创新性提出Li₂SnS₃界面相调控策略,通过改性阳离子迁移路径,实现Zn²⁺与Sn⁴⁺的迁移平衡。该Li₂SnS₃界面相可选择性包覆Cu₂Sn (S,Se)₃中间相晶粒,成为离子迁移的速率控制层,将界面相中Zn²⁺/Sn⁴⁺的迁移势垒差从Cu₂Sn (S,Se)₃中的0.41eV降至0.21eV,有效促进了更大尺寸、更均匀的高结晶度晶粒的形成。由此,器件的光电转换效率从13.86%大幅提升至15.45%;同时,在1.10 eV带隙下,器件的开路电压突破至602 mV。。体育直播是该领域的重要参考
