In article number 1805064, Feng Hou, Ji Liang, and co‐workers fabricate flexible, free‐standing, and continuous nickel sulfide nanosheet/carbon nanotube (NS/CNT) films through a silicamediated conversion process. The nickel sulfide nanosheets with controllable phases and compositions are homogeneously and intimately attached on highly graphitized and fewwalled CNTs. The NS/CNT can be directly used...
An effective, nondestructive, and universal strategy to homogeneously modify freestanding carbon nanotube (CNT) films with various active species is essential to achieve functional electrodes for flexible electrochemical energy storage, which is challenging and has attracted considerable research interest. In this work, a generalizable concept, to utilize silicon oxide as the intermediate to uniformly...

The above article, published online on February 27, 2018 in Wiley Online Library (https://onlinelibrary.wiley.com), has been retracted by agreement between the corresponding authors, the journal Editor‐in‐Chief, José Oliveira, and Wiley‐VCH Verlag GmbH & Co. KGaA. Although the authors stand by the scientific content of the paper, the retraction has been agreed upon due...
The development of cost‐efficient, active, and stable electrode materials as bifunctional catalysts for electrochemical water splitting is crucial to high‐performance renewable energy storage and conversion devices. In this work, the synthesis of Co‐based multi‐metal borides nanochains with amorphous structure is reported for boosting the oxygen evolution (OER) and hydrogen evolution reactions (HER)...
While immunotherapy has a tremendous clinical potential to combat cancer, immune responses generated by conventional cancer immunotherapy remain not enough to completely eliminate tumors, mainly due to the tumor's immunosuppressive microenvironment and heterogeneity of tumor immunogenicity. To improve antitumor immune responses and realize personalized immunotherapy, in this report, endogenous tumor...
In article number 1801372, Hongling Zhang, Zhenzhong Zhang, and co‐workers show that, under local ultrasound treatment, nano Fe3O4 particles (∼10 nm) are released from Ce6/Fe3O4‐L specifically within the tumor. Due to the excellent protein‐bound efficiency and lymph node (LN)‐targeting ability, endogenous tumor antigens are captured and transported to the LNs, thus potentiating cancer immunotherapy...
Development of efficient and durable non‐Pt catalysts for hydrogen evolution reaction (HER) in acid media is highly desirable. Iron nitride has emerged as a promising catalyst for its cost‐effective nature, but the corresponding acidic stability must be promoted. Herein, phosphorus‐decorated Fe2N and reduced graphene oxide (P‐Fe2N/rGO) composite are designed and synthesized. X‐ray photoelectron spectroscopy...
Zinc–air batteries with high‐density energy are promising energy storage devices for the next generation of energy storage technologies. However, the battery performance is highly dependent on the efficiency of oxygen electrocatalyst in the air electrode. Herein, the N, F, and B ternary doped carbon fibers (TD‐CFs) are prepared and exhibited higher catalytic properties via the efficient 4e− transfer...
Here, a Sb‐doped SnO2 (ATO) nanorod underneath an α‐Fe2O3 nanorod sheathed with TiO2 for photoelectrochemical (PEC) water splitting is reported. The experimental results, corroborated with theoretical analysis, demonstrate that the ATO nanorod underlayer effect on the α‐Fe2O3 nanorod sheathed with TiO2 enhances the PEC water splitting performance. The growth of the well‐defined ATO nanorods is reported...
An Ar atmospheric treatment is rationally used to etch and activate hematite nanoflakes (NFs) as photoanodes toward enhanced photoelectrochemical water oxidation. The formation of a highly ordered hematite nanorods (NRs) array containing a high density of oxygen vacancy is successfully prepared through in situ reduction of NFs in Ar atmosphere. Furthermore, a hematite (104) plane and an iron suboxide...
Nanostructured Pt is the most efficient single‐metal catalyst for fuel cell technology. Great efforts have been devoted to optimizing the Pt‐based alloy nanocrystals with desired structure, composition, and shape for boosting the electrocatalytic activity. However, these well‐known controls still show the limited ability in maximizing the Pt utilization efficiency for achieving more efficient fuel...
Controlled membrane fusion of proteinosome‐based protocells is achieved via a hydrogel‐mediated process involving dynamic covalent binding, self‐healing, and membrane reconfiguration at the contact interface. The rate of proteinosome fusion is dependent on dynamic Schiff base covalent interchange, and is accelerated in the presence of encapsulated glucose oxidase and glucose, or inhibited with cinnamyl...
Self‐propelled Au‐BP7@SP Janus‐like nanohybrids with active motion under NIR laser can effectively enhance the temperature of tumors, potentially by converting the kinetic energy into thermal energy, enhancing photothermal tumor therapy. On page 5423, Y.‐S. Li, L. Wang, H. Wang, and co‐workers provide an insight into nanohybrids' effect on photothermal treatment and open a new avenue to cancer treatment...
Au‐BP7@SP nanohybrids with active motion under NIR laser irradiation can effectively enhance the temperature of tumor potentially by converting the kinetic energy to thermal energy, enhancing the killing efficiency of the tumor cells compared with Au@SP. The study provides an insight of nanohybrids' effect on photothermal treatment and opens a new avenue to cancer treatment by using self‐propulsion...
In drug delivery systems, pH‐sensitive polymers are commonly used as drug carriers, and significant efforts have been devoted to the aspects of controlled delivery and release of drugs. However, few studies address the possible autophagic effects on cells. Here, for the first time, using a fluorescent autophagy‐reporting cell line, this study evaluates the autophagy‐induced capabilities of four types...
