Abstract Zinc metal suffers from violent and long‐lasting water‐induced side reactions uncontrollable dendritic Zn growth, which seriously reduce the coulombic efficiency (CE) lifespan of aqueous zinc‐metal batteries (AZMBs). To suppress corresponding harmful effects highly active water, a stable zirconium‐based metal‐organic framework with water catchers decorated inside its sub‐nano channels is used to protect Zn‐metal. Water within narrow can constantly trap molecules solvated Zn‐ions...

This paper presents learning the uncorrelated color space (UCS), independent (ICS), and discriminating (DCS) for face recognition. The new spaces are derived from RGB that defines tristimuli R, G, B component images. While UCS decorrelates its three images using principal analysis (PCA), ICS derives by means of blind source separation, such as (ICA). DCS, which applies discriminant analysis, effective Effective image representation is formed in these concatenating their images, efficient...

Accumulating clinical evidence suggests that lung microbiome is closely linked to the progression of pulmonary diseases; however, it still controversial which specimen type preferred for evaluation microbiome. To address this issue, we established a classical acute injury (ALI) mice model by intratracheal instillation lipopolysaccharides (LPS). We found bacterial DNA obtained from bronchoalveolar lavage fluid (BALF), intact tissue [Lung(i)], after perfused [Lung(p)], and feces one mouse were...

Abstract All inorganic perovskite quantum dots (ABX 3 , A = Cs, B Pb, X Cl, Br, or I) are potential candidates for wide‐color‐gamut display applications. High‐efficiency green and red dot (PeQD) light‐emitting diodes (LEDs) have been achieved, however, development of blue‐emitting devices, especially those with the relatively short wavelengths (<470 nm) meeting National Television System Committee blue standard, lag largely behind, mainly due to poor film quality, low photoluminescence...

Noncommunicable diseases (NCDs) are a major threat to population health worldwide. In Shanghai, China, new pattern of NCD management-self-management-has been developed in community service centres (CHSCs).To clarify how contracting with CHSC-based family doctors (FDs) influences the engagement and effectiveness self-management behaviour among patients.We conducted two waves questionnaire survey (in 2013 2016) collect data on patients NCDs. Separate logistic regression models longitudinal...

Abstract Highly efficient green and red perovskite quantum dots (PeQDs) light‐emitting diodes (PeQDLEDs) have been achieved. However, blue PeQDLEDs, especially those with the relatively short wavelengths (<470 nm) meeting National Television System Committee standard, struggled to match high efficiency stability of their counterparts. The main critical problems are low photoluminescence yield (PLQY) poor PeQDs, as well unfavorable device structure. Herein, a strategy codoping Mn 2+ Ni in...
