Here we argue that the putative quantum critical point in the prototypical unconventional superconductor CeCoIn5 is characterized by the delocalization of electrons in a transition that connects two Fermi surfaces of different volumes, with no apparent broken symmetry. Drawing on established theory of f-electron metals, we discuss an interpretation for such a transition that involves the fractionalization of spin and charge, a model that effectively describes the anomalous transport behavior we measured for the Hall effect.材(Cai)料(Liao)科(Ke)学(Xue)Materials ScienceSingle-walled zeolitic nanotubes单(Dan)壁(Bi)分(Fen)子(Zi)筛(Shai)纳(Na)米(Mi)管(Guan)▲ 作(Zuo)者(Zhe)：AKSHAY KORDE, BYUNGHYUN MIN, ELINA KAPACA, OMAR KNIO, IMAN NEZAM, ZIYUAN WANG, et al.▲ 链(Lian)接(Jie)：https://www.science.org/doi/10.1126/science.abg3793▲ 摘(Zhai)要(Yao)研(Yan)究(Jiu)组(Zu)报(Bao)道(Dao)了(Liao)具(Ju)有(You)微(Wei)孔(Kong)分(Fen)子(Zi)筛(Shai)壁(Bi)的(De)单(Dan)壁(Bi)硅(Gui)酸(Suan)铝(Lv)纳(Na)米(Mi)管(Guan)的(De)合(He)成(Cheng)和(He)结(Jie)构(Gou)。这(Zhe)种(Zhong)准(Zhun)一(Yi)维(Wei)分(Fen)子(Zi)筛(Shai)由(You)波(Bo)拉(La)型(Xing)结(Jie)构(Gou)导(Dao)向(Xiang)剂(Ji)（SDA）组(Zu)装(Zhuang)而(Er)成(Cheng)，该(Gai)分(Fen)子(Zi)筛(Shai)含(Han)有(You)一(Yi)个(Ge)中(Zhong)心(Xin)联(Lian)苯(Ben)基(Ji)团(Tuan)，由(You)C10烷(Wan)基(Ji)链(Lian)连(Lian)接(Jie)到(Dao)奎(Kui)宁(Ning)环(Huan)端(Duan)基(Ji)。高(Gao)分(Fen)辨(Bian)率(Lv)电(Dian)子(Zi)显(Xian)微(Wei)镜(Jing)和(He)衍(Yan)射(She)及(Ji)其(Qi)他(Ta)支(Zhi)持(Chi)方(Fang)法(Fa)揭(Jie)示(Shi)了(Liao)一(Yi)种(Zhong)独(Du)特(Te)的(De)壁(Bi)结(Jie)构(Gou)，它(Ta)是(Shi)两(Liang)种(Zhong)分(Fen)子(Zi)筛(Shai)结(Jie)构(Gou)类(Lei)型(Xing)（β和(He)MFI）的(De)特(Te)征(Zheng)构(Gou)建(Jian)层(Ceng)的(De)混(Hun)合(He)体(Ti)。这(Zhe)种(Zhong)混(Hun)合(He)结(Jie)构(Gou)产(Chan)生(Sheng)于(Yu)弯(Wan)曲(Qu)纳(Na)米(Mi)管(Guan)壁(Bi)形(Xing)成(Cheng)过(Guo)程(Cheng)中(Zhong)应(Ying)变(Bian)能(Neng)的(De)最(Zui)小(Xiao)化(Hua)。由(You)于(Yu)SDA分(Fen)子(Zi)的(De)自(Zi)组(Zu)装(Zhuang)，纳(Na)米(Mi)管(Guan)的(De)形(Xing)成(Cheng)导(Dao)致(Zhi)介(Jie)观(Guan)结(Jie)构(Gou)的(De)早(Zao)期(Qi)出(Chu)现(Xian)。SDA分(Fen)子(Zi)的(De)联(Lian)苯(Ben)核(He)心(Xin)基(Ji)团(Tuan)证(Zheng)明(Ming)了(Liao)π堆(Dui)积(Ji)，外(Wai)围(Wei)的(De)奎(Kui)宁(Ning)环(Huan)基(Ji)团(Tuan)则(Ze)证(Zheng)明(Ming)了(Liao)微(Wei)孔(Kong)壁(Bi)结(Jie)构(Gou)。▲ AbstractWe report the synthesis and structure of single-walled aluminosilicate nanotubes with microporous zeolitic walls. This quasi-one-dimensional zeolite is assembled by a bolaform structure-directing agent (SDA) containing a central biphenyl group connected by C10 alkyl chains to quinuclidinium end groups. High-resolution electron microscopy and diffraction, along with other supporting methods, revealed a unique wall structure that is a hybrid of characteristic building layers from two zeolite structure types, beta and MFI. This hybrid structure arises from minimization of strain energy during the formation of a curved nanotube wall. Nanotube formation involves the early appearance of a mesostructure due to self-assembly of the SDA molecules. The biphenyl core groups of the SDA molecules show evidence of π stacking, whereas the peripheral quinuclidinium groups direct the microporous wall structure.Metastable Dion-Jacobson 2D structure enables efficient and stable perovskite solar cells亚(Ya)稳(Wen)态(Tai)Dion-Jacobson二(Er)维(Wei)结(Jie)构(Gou)实(Shi)现(Xian)高(Gao)效(Xiao)稳(Wen)定(Ding)的(De)钙(Gai)钛(Zuo)矿(Kuang)太(Tai)阳(Yang)能(Neng)电(Dian)池(Chi)▲ 作(Zuo)者(Zhe)：FEI ZHANG, SO YEON PARK, CANGLANG YAO, HAIPENG LU, SEAN P.

We maximized hole transport across the layers of a metastable Dion-Jacobson (DJ) 2D perovskite that tuned the orientational arrangements of asymmetric bulky organic molecules. The reduced energy barrier for hole transport increased out-of-plane transport rates by a factor of 4 to 5, and the power conversion efficiency (PCE) for the 2D PSC was 4.9%. With the metastable DJ 2D surface layer, the PCE of three common 3D PSCs was enhanced by approximately 12 to 16% and could reach approximately 24.7%. For a triple-cation–mixed-halide PSC, 90% of the initial PCE was retained after 1000 hours of 1-sun operation at ~40°C in nitrogen.Capturing the swelling of solid-electrolyte interphase in lithium metal batteries观(Guan)测(Ce)锂(Zuo)金(Jin)属(Shu)电(Dian)池(Chi)固(Gu)体(Ti)电(Dian)解(Jie)质(Zhi)中(Zhong)间(Jian)相(Xiang)的(De)膨(Peng)胀(Zhang)▲ 作(Zuo)者(Zhe)：ZEWEN ZHANG, YUZHANG LI, RONG XU, WEIJIANG ZHOU, YANBIN LI, SOLOMON T.

This leads to substantial gaps in our understanding of the structure and chemistry of key interfaces in battery systems. We adopt and modify a thin film vitrification method to preserve the sensitive yet critical interfaces in batteries at native liquid electrolyte environments to enable cryo–electron microscopy and spectroscopy. We report substantial swelling of the solid-electrolyte interphase (SEI) on lithium metal anode in various electrolytes. The swelling behavior is dependent on electrolyte chemistry and is highly correlated to battery performance. Higher degrees of SEI swelling tend to exhibit poor electrochemical cycling.地(Di)球(Qiu)科(Ke)学(Xue)Earth ScienceOn the relative temperatures of Earth’s volcanic hotspots and mid-ocean ridges地(Di)球(Qiu)火(Huo)山(Shan)热(Re)点(Dian)和(He)大(Da)洋(Yang)中(Zhong)脊(Ji)的(De)相(Xiang)对(Dui)温(Wen)度(Du)▲ 作(Zuo)者(Zhe)：XIYUAN BAO, CAROLINA R.

However, Tex estimates are limited in geographical coverage and often inconsistent for individual hotspots. We infer the temperature of oceanic hotspots and ridges simultaneously by converting seismic velocity to temperature. We show that while ~45% of plume-fed hotspots are hot (Tex ≥ 155°C), ~15% are cold (Tex ≤ 36°C) and ~40% are not hot enough to actively upwell (50°C ≤ Tex ≤ 136°C). Hot hotspots have an extremely high helium-3/helium-4 ratio and buoyancy flux, but cold hotspots do not. The latter may originate at upper mantle depths. Alternatively, the deep plumes that feed them may be entrained and cooled by small-scale convection.公(Gong)共(Gong)卫(Wei)生(Sheng)Public HealthImmune correlates analysis of the mRNA-1273 COVID-19 vaccine efficacy clinical trialmRNA-1273新(Xin)冠(Guan)疫(Yi)苗(Miao)效(Xiao)力(Li)临(Lin)床(Chuang)试(Shi)验(Yan)的(De)免(Mian)疫(Yi)相(Xiang)关(Guan)分(Fen)析(Xi)▲ 作(Zuo)者(Zhe)：PETER B.

These immune markers were measured at the time of second vaccination and 4 weeks later, with values reported in standardized World Health Organization international units. All markers were inversely associated with COVID-19 risk and directly associated with vaccine efficacy. Vaccine recipients with postvaccination 50% neutralization titers 10, 100, and 1000 had estimated vaccine efficacies of 78% (95% confidence interval, 54 to 89%), 91% (87 to 94%), and 96% (94 to 98%), respectively. These results help define immune marker correlates of protection and may guide approval decisions for messenger RNA (mRNA) COVID-19 vaccines and other COVID-19 vaccines.
