Through inducing death receptor (DR) clustering to activate downstream signaling, tumor necrosis factor related apoptosis inducing ligand (TRAIL) trimers trigger apoptosis of tumor cells. However, the poor agonistic activity of current TRAIL‐based therapeutics limits their antitumor efficiency. The nanoscale spatial organization of TRAIL trimers at different interligand distances is still challenging,...
Functional passivators are conventionally utilized in modifying the crystallization properties of perovskites to minimize the non‐radiative recombination losses in perovskite light‐emitting diodes (PeLEDs). However, the weak anchor ability of some commonly adopted molecules has limited passivation ability to perovskites and even may desorb from the passivated defects in a short period of time, which...
Efficient Light‐Emitting Diodes
In article number 2205336, Yue‐Min Xie, You‐Yong Li, Man‐Keung Fung, and co‐workers introduce a novel multidentate molecule (Formamidine Sulfinic Acid, FSA) to heal perovskite defects, where the intense bonding strength of the S≐O and –NH2 groups of the multidentate molecule to the undercoordinated Pb defects can effectively facilitate the passivation of the perovskites,...
The high capacity of Li‐rich and Mn‐based (LRM) cathode materials is originally due to the unique hybrid anion‐ and cation redox, which also induces detrimental oxygen escape. Furthermore, the counter diffusion of released oxygen (into electrolyte) and induced oxygen vacancies (into the interior bulk phase) that occurs at the interface will cause uncontrolled phase collapse and other issues. Therefore,...
Designing and constructing bimetallic hierarchical structures is vital for the conversion‐alloy reaction anode of sodium‐ion batteries (SIBs). Particularly, the rationally designed hetero‐interface engineering can offer fast diffusion kinetics in the interface, leading to the improved high‐power surface pseudocapacitance and cycling stability for SIBs. Herein, the hierarchical zinc–tin sulfide nanocages...
With the popularity of low‐dose computed tomography (LDCT) in clinical examination of the lung, the prevalence of pulmonary nodules has significantly increased, thus significantly improving the early diagnosis of lung cancer, but also potentially contributing to overtreatment. This study aims to develop a noninvasive method to assist in diagnosing the pulmonary nodules. To do so, 3798 patients are...
Metal–organic frameworks (MOFs) can be fine‐tuned to boost sorbent‐sorbate interactions in order to improve gas sorption and separation performance, but the design of MOFs with ideal structural features for gas separation applications remains a challenge. Herein it is reported that unsaturated alkali metal sites can be immobilized in MOFs through a tetrazole based motif and that gas affinity can thereby...
In article number 1900426, Ze Chang, Xian‐He Bu, and co‐workers demonstrate a new strategy for the immobilization of alkali metal cations (K+) in metal–organic frameworks (MOFs) toward gas affinity boosting. The immobilized K+ cations could be desolvated and serve as traps for CO2 capture, which effectively enhances the CO2 sorption performances of the MOFs.
Neuromorphic systems aim to implement large‐scale artificial neural network on hardware to ultimately realize human‐level intelligence. The recent development of nonsilicon nanodevices has opened the huge potential of full memristive neural networks (FMNN), consisting of memristive neurons and synapses, for neuromorphic applications. Unlike the widely reported memristive synapses, the development...
The rapid development of electric vehicles and modern personal electronic devices is severely hindered by the limited energy and power density of the existing power sources. Here a novel hybrid Zn battery is reported which is composed of a nanostructured transition metal oxide‐based positive electrode (i.e., Co3O4 nanosheets grown on carbon cloth) and a Zn foil negative electrode in an aqueous alkaline...
In article number 1603435, by Rong Zhao and co‐workers, graphene quantum dots are introduced into memristive devices as nano oxygen‐reservoirs. As a result, repeatable analog states of memristive devices are attained with nearly 85% reduction in variations, indicating highly controllable synaptic weight changes. The controllable artificial synapses could equip neural networks with accurate and efficient...
Memristive devices, having a huge potential as artificial synapses for low‐power neural networks, have received tremendous attention recently. Despite great achievements in demonstration of plasticity and learning functions, little progress has been made in the repeatable analog resistance states of memristive devices, which is, however, crucial for achieving controllable synaptic behavior. The controllable...
A simple method to prepare metal‐organic framework (MOF) nanotubes is developed by employing polyoxometalates (POMs) as modulators. The local structure of the MOF nanotubes is investigated combining XANES and EXAFS studies. These nanotubes show both an excellent catalytic performance in the detoxification of sulfur compounds in O2 atmosphere and a remarkable cycling stability as the anode material...
