In-sensor computing hardware based on emerging reconfigurable photosensors can effectively reduce redundant data and decrease power consumption, which greatly promote the evolution of machine vision. However, because complex device structures low integration abilities, common architectures mainly lie in two dimensions, resulting time area efficiencies. Here we propose a three-dimensional (3D) neuromorphic photosensor array for parallel in-sensor image processing. It is constructed vertical...
Background Bacteria play critical roles in marine nutrient cycles by incorporating and redistributing dissolved organic matter (DOM) inorganic nutrients the ocean. TonB-dependent transporter (TBDT) proteins allow Gram-negative bacteria to take up scarce resources from nutrient-limiting environments as well siderophores, heme, vitamin B12, recently identified carbohydrates. Thus, characterization of TBDT distribution functions is essential better understand contribution DOM assimilation its...

Abstract The assembly of spherical fullerenes, or buckyballs, into single crystals for crystallographic identification often suffers from disordered arrangement. Here we show a chiral configuration decapyrrylcorannulene that has concave ‘palm’ corannulene and ten flexible electron-rich pyrryl group ‘fingers’ to mimic the smart molecular ‘hands’ self-adaptably cradling various buckyballs in (+)hand-ball-hand(−) mode. As exemplified by 15 buckyball structures representing pristine, exohedral,...
Pristine fullerene C60 is an excellent electron transport material for state-of-the-art inverted structure perovskite solar cells (PSCs), but its low solubility leaves thermal evaporation as the only method depositing it into a high-quality layer (ETL). To address this problem, we herein introduce highly soluble bowl-shaped additive, corannulene, to assist in -assembly smooth and compact film through favorable bowl-ball interaction. Our results show that not corannulene can dramatically...

In regular perovskite solar cells (PSCs), the commonly used electron transport layer (ETL) is titanium oxide (TiO2). Nevertheless, preparation of a high-quality TiO2 ETL demands an elevated-temperature sintering procedure, unfavorable for fabrication PSCs on flexible substrates. Besides, TiO2-based devices often suffer from notorious photocurrent hysteresis and serious light soaking instability, limiting their potential commercialization. Herein, novel pyridine-functionalized fullerene...
Perovskite solar cell (PSC) is a potential next‐generation photovoltaic technology alternative to the conventional competitors including polycrystalline silicon, cadmium telluride, and copper indium gallium diselenide cells. Particularly, functionalized fullerenes play crucial roles as charge transport layers, interfacial additives in perovskite photovoltaics, dramatically contributing promotion of power conversion efficiency (PCE) stability. As field advances rapidly, importance rationally...
