Bifacial Passivation of Organic Hole Transport Interlayer for NiO -Based p-i-n Perovskite Solar Cells.

Adv Sci (Weinh) 2019 Mar 29;6(6):1802163. Epub 2019 Jan 29.

Department of Energy Systems Research Ajou University Suwon 16499 Republic of Korea.

Methoxy-functionalized triphenylamine-imidazole derivatives that can simultaneously work as hole transport materials (HTMs) and interface-modifiers are designed for high-performance and stable perovskite solar cells (PSCs). Satisfying the fundamental electrical and optical properties as HTMs of p-i-n planar PSCs, their energy levels can be further tuned by the number of methoxy units for better alignment with those of perovskite, leading to efficient hole extraction. Moreover, when they are introduced between perovskite photoabsorber and low-temperature solution-processed NiO interlayer, widely featured as an inorganic HTM but known to be vulnerable to interfacial defect generation and poor contact formation with perovskite, nitrogen and oxygen atoms in those organic molecules are found to work as Lewis bases that can passivate undercoordinated ion-induced defects in the perovskite and NiO layers inducing carrier recombination, and the improved interfaces are also beneficial to enhance the crystallinity of perovskite.

Uncovering the Effect of Lattice Strain and Oxygen Deficiency on Electrocatalytic Activity of Perovskite Cobaltite Thin Films.

Adv Sci (Weinh) 2019 Mar 30;6(6):1801898. Epub 2019 Jan 30.

Materials Science and Engineering Georgia Institute of Technology Atlanta GA USA.

Developing cost effective electrocatalysts with high oxygen evolution reaction (OER) activity is essential for large-scale application of many electrochemical energy systems. Although the impacts of either lattice strain or oxygen defects on the OER performance of oxide catalysts have been extensively investigated, the effects of both factors are normally treated separately. In this work, the coupled effects of both strain and oxygen deficiency on the electrocatalytic activity of LaSrCoO (LSC) thin films grown on single crystal substrates (LaAlO3 (LAO) and SrTiO3 (STO)) are investigated.

Tumors and Their Microenvironment Dual-Targeting Chemotherapy with Local Immune Adjuvant Therapy for Effective Antitumor Immunity against Breast Cancer.

Adv Sci (Weinh) 2019 Mar 30;6(6):1801868. Epub 2019 Jan 30.

Key Laboratory of Drug-Targeting and Drug Delivery System of the Education Ministry Sichuan Engineering Laboratory for Plant-Sourced Drug and Sichuan Research Center for Drug Precision Industrial Technology West China School of Pharmacy Sichuan University Chengdu 610064 P. R. China.

Chemotherapy turns tumor cells into "tumor vaccines" by immunogenic cell death (ICD). However, it remains a challenge to exploit chemotherapy-induced "tumor vaccines" for solid cancer immunotherapy due to the inefficient effector T cells activation and tumor microenvironment immunosuppression. Here, a matrix metalloprotease 2 responsive liposome (PEG-FA-Lip) composed of cleavable PEG chains covering the folate (FA)-modified liposome is developed to deliver ICD inducer doxorubicin.

Adv Sci (Weinh) 2019 Mar 23;6(6):1801837. Epub 2019 Jan 23.

Physical Intelligence Department Max Planck Institute for Intelligent Systems 70569 Stuttgart Germany.

Collective control of mobile microrobotic swarms is indispensable for their potential high-impact applications in targeted drug delivery, medical diagnostics, parallel micromanipulation, and environmental sensing and remediation. Without integrated electronics for sensing and actuation, current microrobotic systems should rely on physical interactions among individual microrobots for local communication and cooperation. Here, it is shown that mobile microrobotic swarms with well-defined collective behavior can be designed by engineering magnetic interactions among individual units. Read More

State Key Laboratory of Pharmaceutical Biotechnology School of Life Sciences Nanjing University Nanjing Jiangsu 210023 China.

Although pancreatic islet transplantation holds promise for the treatment of type I diabetes, its application has been significantly hampered by transplant rejection. Here, an approach is demonstrated to support trans-species islet beta cells from a rat to grow and function in the body of a mouse host while overcoming graft rejection. This approach, which builds on remodeling of the mouse testicle by local injection of a tumor homogenate, establishes an immunosuppressive and proregenerative niche in the testicle. Read More

The Role of Chloride Incorporation in Lead-Free 2D Perovskite (BA)SnI: Morphology, Photoluminescence, Phase Transition, and Charge Transport.

Adv Sci (Weinh) 2019 Mar 20;6(5):1802019. Epub 2019 Jan 20.

School of Optical and Electronic Information and Wuhan National Laboratory for Optoelectronics Huazhong University of Science and Technology Wuhan 430074 China.

The incorporation of chloride (Cl) into methylammonium lead iodide (MAPbI) perovskites has attracted much attention because of the significantly improved performance of the MAPbI-based optoelectronic devices with a negligible small amount of Cl incorporation. It is expected that the Cl incorporation in 2D perovskites with layered nature would be much more efficient and thus can greatly alter the morphology, optical properties, phase transition, and charge transport; however, studies on those aspects in 2D perovskites remain elusive up to date. Here, a one-pot solution method to synthesize the Cl-doped lead-free 2D perovskite (BA)SnI with various Cl incorporation concentrations is reported and how the Cl incorporation affects the morphology change, photoluminescence, phase transition, and charge transport is investigated.
