The polycrystalline feature of solution-processed perovskite film and its ionic nature inevitably incur substantial crystallographic defects, especially at the surface grain boundaries (GBs). Here, a simple defect passivation method was exploited by post-treating CH3NH3PbI3 (MAPbI3) with rationally selected diammonium iodide. molecular structure used iodide discovered to play critical role in affecting phase purity treated MAPbI3. Both NH3I(CH2)4NH3I NH3I(CH2)2O(CH2)2NH3I (EDBE) induce...
A low-bandgap (1.33 eV) Sn-based MA0.5 FA0.5 Pb0.75 Sn0.25 I3 perovskite is developed via combined compositional, process, and interfacial engineering. It can deliver a high power conversion efficiency (PCE) of 14.19%. Finally, four-terminal all-perovskite tandem solar cell demonstrated by combining this with semitransparent MAPbI3 to achieve 19.08%.
Semiconductor quantum dots (QDs) exhibit unique optical and photophysical properties that offer significant advantages over organic dyes as labels for chemo/bio-sensing. This review addresses the methods metal ion detection with QDs, including photoluminescent, electrochemiluminescent, photoelectrochemical, electrochemical approaches. The main mechanisms of direct interaction between QDs ions which lead to photoluminescence being either off or on, are discussed in detail. These interactions...
Abstract Entirely low‐temperature solution‐processed (≤100 °C) planar p‐i‐n perovskite solar cells (PSCs) offer great potential for commercialization of roll‐to‐roll fabricated photovoltaic devices. However, the stable inorganic hole‐transporting layer (HTL) in PSCs is usually processed at high temperature (200–500 °C), which far beyond tolerant (≤150 fabrication. In this context, NiO x nanoparticles (NPs) are an excellent candidate to serve as HTL PSCs, owing their solution processability...
Synthesizing 2D metal-organic frameworks (2D MOFs) in high yields and rational tailoring of the properties a predictable manner for specific applications is extremely challenging. Now, series porphyrin-based lanthanide MOFs (Ln-TCPP, Ln=Ce, Sm, Eu, Tb, Yb, TCPP=tetrakis(4-carboxyphenyl) porphyrin) with different thickness were successfully prepared household microwave oven. The as-prepared Ln-TCPP nanosheets showed thickness-dependent photocatalytic performances towards photooxidation...
Abstract Background Despite therapeutic advances, once a cancer has metastasized to the bone, it represents highly morbid and lethal disease. One third of patients with advanced clear cell renal carcinoma (ccRCC) present bone metastasis at time diagnosis. However, metastatic niche in humans, including immune stromal microenvironments, not been well-defined, hindering progress towards identification targets. Methods We collected fresh patient samples performed single-cell transcriptomic...

Controlled doping for adjustable material polarity and charge carrier concentration is the basis of semiconductor materials devices, it much more difficult to achieve in ionic semiconductors (e.g., ZnO GaN) than covalent Si Ge), due high intrinsic defect density semiconductors. The organic–inorganic perovskite material, which frenetically being researched applications solar cells beyond, also an semiconductor. Here we present Ag-incorporated films planar heterojunction cells. Partial...
Photodetectors with ultrafast response are explored using inorganic/organic hybrid perovskites. High responsivity and fast optoelectronic achieved due to the exceptional semiconducting properties of perovskite materials. However, most perovskite‐based photodetectors exploited date centered on Pb‐based perovskites, which only afford spectral across visible spectrum. This study demonstrates a high‐performance near‐IR (NIR) photodetector stable low‐bandgap Sn‐containing perovskite, (CH 3 NH )...

The PEC constructed by plasmon-enhanced photoactive material (namely, Au NPs/Yb-TCPP) specific DNA aptamer against S protein. NPs/Yb-TCPP fabricated in situ growth of NPs on the surface 2D...
Perylene diimide tethered pillar[5]arene derivatives form aggregates in non-polar organic solvents, and the complexation of cationic amino acid ethyl ester (cAA-OEt) with induce a central-to-planar-to-helical chirality transfer, leading to intensive circular dichroism (CD) signals having dissymmetric factors (gabs ) up 3.67×10-2 . The hierarchical chiral induction exhibited an intriguing threshold dose effect, namely, does not occur low concentration range cAA-OEt but is triggered when...
