The open circuit voltage (VOC) losses at multiple interfaces within perovskite solar cells (PSCs) limit the improvements in power conversion efficiency (PCE). Herein, a tailored strategy is proposed to reduce the energy offset at both hetero‐interfaces within PSCs to decrease the VOC losses. For the interface of perovskite and electron transport layer where exists a mass of defects, it uses the pyromellitic...
The development of novel method for drug‐resistant bacteria detection is imperative. A simultaneous dual‐gene Test of methicillin‐resistant Staphylococcus aureus (MRSA) is developed using an Argonaute‐centered portable biosensor (STAR). This is the first report concerning Argonaute‐based pathogenic bacteria detection. Simply, the species‐specific mecA and nuc gene are isothermally amplified using...
Assembled gold nanoparticle (AuNP) superstructures can generate unique physicochemical characteristics and be used in various applications, thus becoming an attractive research field. Recently, several DNA‐assisted gold nanoparticle assembly methods have been rigorously developed that typically require a non‐catalytic equimolar molecular assembly to guarantee the designed assembly. Although efficient...
Droplet microfluidics are extensively utilized to generate monodisperse cell‐laden microgels in biomedical applications.
