Decorating hole transport material with −CF_(3) groups for highly efficient and stable perovskite solar cells

The hole transport material (HTM) plays an extremely important role to determine the power conversion efficiency (PCE) and the stability of perovskite solar cells (PSCs). Herein, we report an effective strategy to improve the performance of HTMs by introducing −CF_(3) groups via the rational decorative mode. Upon direct attachment or nonconjugated alkoxyl bridging of −CF_(3) groups on the terminal diphenylamines, the resulting molecular HTMs, i.e., 2,7-BCzA4CF_(3) and 2,7-BCzA4OCCF_(3), show distinct properties. Compared with 2,7-BCzA4CF_(3), the nonconjugated alkoxyl bridging −CF_(3) group-based 2,7-BCzA4OCCF_(3) exhibits better thermal stability, hydrophobicity, and a dramatically upgraded hole mobility by 135.7-fold of magnitude to 1.71 × 10^(−4) cm^(2) V^(−1) S^(−1). The PSCs with 2,7-BCzA4OCCF_(3) as HTM exhibit an PCE of up to 20.53% and excellent long-term stability, maintaining 92.57% of their performance for 30 days in air with humidity of 30% without encapsulation. This work provides beneficial guidelines for the design of new HTMs for efficient and stable PSCs.

In situ apolipoprotein E-enriched corona guides dihydroartemisinin-decorating nanoparticles towards LDLr-mediated tumor-homing chemotherapy

The therapeutic efficiency of active targeting nanoparticulate drug delivery systems(nano-DDS)is highly compromised by the plasma proteins adsorption on nanoparticles(NPs)surface,which significantly hinders cell membrane receptors to recognize the designed ligands,and provokes the off-target toxicity and rapid clearance of NPs in vivo.Herein,we report a novel dihydroartemisinin(DHA)-decorating nano-DDS that in situ specifically recruits endogenous apolipoprotein E(apoE)on the NPs surface.The apoE-anchored corona is able to prolong PLGA-PEG2000-DHA(PPD)NPs circulation capability in blood,facilitate NPs accumulating in tumor cells by the passive enhanced permeability and retention(EPR)effect and low-density lipoprotein receptor(LDLr)-mediated target transport,and ultimately improve the in vivo antitumor activity.Our findings demonstrate that the strategy of in situ regulated apoE-enriched corona ensures NPs an efficient LDLr-mediated tumor-homing chemotherapy.

Decorating and Filling of Multi-Walled Carbon Nanotubes with TiO₂Nanoparticles via Wet Chemical Method

Multi-walled carbon nanotubes (MWCNTs) have been successfully modified with TiO2 nanoparticles via wet chemical method. For this purpose tetra chloride titanium (TiCl4) was used as titanium source. MWCNTs were exposed at different amount of TiCl4 (0.25 and 0.1 ml) and different soaking times. The modified MWCNTs have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). TEM results showed that the MWCNTs were fully decorated with TiO2 at short term immersion. Increasing soaking time caused to fill the MWCNTs with TiO2 nanoparticles. The results showed that the amount of precursor had a significant role on quantity of decoration. The decoration of outer surface of MWCNTs with TiO2 was more noticeable at large amount of TiCl4. XRD results revealed that the crystalline structure of TiO2 on the surface and inner of MWCNTs was rutile. The average size of TiO2 nanoparticles which modified MWCNTs were 20 nm.

Effect of Partial Replacement of Fly Ash by Decoration Waste Powder on the Fresh and Mechanical Properties of Geopolymer Masonry Mortar

This study aims to investigate the feasibility of using decoration waste powder(DWP)as a partial replacement for fly ash(FA)in the preparation of geopolymer masonry mortar,and to examine the effect of different DWP replacement rates(0%-40%)on the fresh and mechanical properties of the mortar.The results showed that each group of geopolymer masonry mortar exhibited excellent water retention performance,with a water retention rate of 100%,which was due to the unique geopolymer mortar system and high viscosity of the alkaline activator solution.Compared to the control group,the flowability of the mortar containing lower contents of DWP(10%and 20%)was higher.However,as the DWP replacement rate further increased,the flowability gradually decreased.The DWP could absorb the free water in the reaction system of geopolymer mortar,thereby limiting the occurrence of geopolymerization reaction.The incorporation of DWP in the mortar resulted in a decrease in compressive strength compared to the mortar without DWP.However,even at a replacement rate of 40%,the compressive strength of the mortar still exceeded 15 MPa,which met the requirements of the masonry mortar.It was feasible to use DWP in the geopolymer masonry mortar.Although the addition of DWP caused some performance loss,it did not affect its usability.

Nest decoration:Black feathers prevent Crested Mynas from nest usurpation

Nests are important structures for birds to raise their offspring and for signaling.Many birds incorporate feathers into the nest,since feathers were traditionally thought to serve the function of insulation.Hypotheses in recent years have considered that some birds place feathers in conspicuous locations in the nest for decoration to trigger a fear response in the competitors.In this study,we investigated whether decorative feathers could deter nest usurpation by Crested Mynas(Acridotheres cristatellus)by manipulating nest box contents.The results revealed that Crested Mynas preferred black feathers to white feathers as decorations and occupied nest boxes decorated with black feathers significantly less than those decorated with white feathers,suggesting that black decorative feathers in the nest could be more effective in preventing nest usurpation by Crested Mynas and that white decorative feathers may have other functions.The black feathers in the nest are prominently placed at the edge of the nest to convey the message that“this nest is occupied”or“the owner of this nest has been preyed upon”to visitor Crested Mynas,thus effectively preventing them from usurping the nest at a later stage.
