Is There A Pure Electronic Ferroelectric?
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

ABSTRACT The focus on wind power frequency regulation has largely been on individual wind farms, which presents challenges in meeting the coordinated operation needs of multiple stations within large‐scale installations. To address issues of model simplification and accuracy, we propose a large‐scale wind farm equivalent modeling method based on ...

云南省由于先前没有兔狲(Otocolobus manul)的野外实体影像资料,因此无法确认其在云南省有分布。依托第二次青藏高原综合科学考察,项目团队于2020年8月—2024年12月在云南省迪庆藏族自治州香格里拉市累计安装180台红外相机进行野生动物本底资源调查。在2024年9月19日记录到一段兔狲(Otocolobus manul)的野外活动影像,该影像为云南省首例兔狲野外纪录资料,证实了兔狲在云南省的分布。

Delayed Tropical Asian Summer Monsoon Onset in Recent Decades
Abstract This study reveals that the onset of tropical Asian summer monsoon (TASM) experienced a pronounced interdecadal delay (about one week) after the late‐2000s. Both the large‐scale seasonal transition reflected by EOF analysis and the monsoon onset dates defined by local rainfall exhibited a clear interdecadal change.

为获得高纯度的澳洲坚果蛋白粉,以低纯度澳洲坚果蛋白粉为原料,采用单因素试验和正交试验确定糖化酶纯化澳洲坚果蛋白粉的最佳工艺条件,在最佳工艺条件下进行中试生产实践(澳州坚果仁—压榨制油—粉碎—脱脂饼粉—加水磨浆—碱溶酸沉—酶解纯化—喷雾干燥—纯化蛋白粉),对纯化后蛋白粉的溶解度、乳化性、持水性和吸油性进行测定,并比较了纯化前后蛋白粉的氨基酸组成及含量。结果表明:澳洲坚果蛋白粉最佳纯化工艺条件为加酶量100 U/g、酶解温度55 ℃、酶解时间90 min、料液比1∶ 8,在此条件下进行中试生产实践 ...

Modification of bamboo cell walls using chemical in‐situ bonding was carried out, while optimizing the arrangement of bamboo fibers. Additionally, an N‐P‐B flame retardant system was formed within the bamboo material to develop an ultra‐strong flame retardant bamboo‐based composite.

ABSTRACT Existing literature largely agrees that authoritarian regimes establish channels for political participation to gather valuable information on citizens' anti‐regime sentiments and policy preferences and to supervise lower‐level bureaucrats and firms.

旨在为澳洲坚果粕的综合利用及高值化产品加工提供参考,以澳洲坚果脱脂粕粉为原料,采用单因素试验和正交试验确定复合酶增溶改性与纯化制备速溶蛋白粉与分离蛋白粉的最佳工艺条件,并进行中试生产实践同步制备速溶蛋白粉与分离蛋白粉,对2种蛋白粉的功能特性和氨基酸组成进行测定。结果表明:澳洲坚果速溶蛋白粉最佳增溶工艺条件为中性蛋白酶与纤维素酶质量比2∶ 1、加酶量1.5%(以脱脂粕粉质量计)、酶解时间120 min、料液比1∶ 4;分离蛋白粉最佳纯化工艺条件为糖化酶、谷氨酰胺转氨酶与单宁酶质量比2∶ 2∶ 1、加酶量1
