We experimentally demonstrate the first metamaterial "illusion optics" device--an "invisible gateway" by using a transmission-line medium. The device contains an open channel that can block waves at particular frequency range. also such work in broad
Gold nanostars were developed for cancer cell-targeted NIR-I/II SERS-imaging and PPTT.
The novel Ba2Gd2Si4O13:Ce3+,Tb3+ phosphors were systemically investigated by fluorescent method for the first time. Through an efficient energy transfer process, obtained exhibit both a blue emission of Ce3+ and yellowish green Tb3+ with considerable intensity under near-ultraviolet excitation (300-370 nm). Tuning content can generate varied hues from to white eventually green. quantum efficiency phosphor Ba2(Gd0.88Ce0.02Tb0.1)2Si4O13 is 82.3% commercial ZnS:Ag+,Cl- phosphor. Our results...
Abstract Nanobodies, single-domain antibodies derived from variable domain of camelid or shark heavy-chain antibodies, have unique properties with small size, strong binding affinity, easy construction in versatile formats, high neutralizing activity, protective efficacy, and manufactural capacity on a large-scale. Nanobodies been arisen as an effective research tool for development nanobiotechnologies variety applications. Three highly pathogenic coronaviruses (CoVs), SARS-CoV-2, SARS-CoV,...

We focus on evaluating current...
High-performance sound sensors that are compact, cost-effective, and versatile crucial for their widespread adoption in consumer electronics industrial applications. In this work, we propose a fast compact photoelectric sensor comprising Gallium nitride (GaN) integrated transceiver chip Polydimethylsiloxane- coated argentum (PDMS/Ag) composite film. The GaN includes light-emitting diode photodetector (PD) with identical multi-quantum well structures, while the PDMS/Ag film is connected to...

A series of compact La/O-vacant La(1-x)CoO(3-y) compounds were prepared by a cold high-pressure procedure, and their thermoelectric (TE) properties investigated. Compared with the ion-substituted hole-type LaCoO(3) systems (e.g., La(1-x)Sr(x)CoO(3)), thermal conduction is noticeably reduced La/O vacancies, whereas electric transport less influenced, which results in an efficient ZT enhancement. We demonstrate that large conductivity reduction originates from strong point-defect scattering,...
