High‐radiance near‐infrared (NIR) phosphor‐converted light‐emitting diodes (pc‐LEDs) are demanded for wearable biosensing devices and the properties of these pc‐LEDs are highly dependent on the performance of the NIR phosphor. An ultraviolet–visible and NIR‐responded broadband NIR NaScGe2O6:Cr3+ phosphor is reported. Under 490 nm excitation, NaScGe2O6:Cr3+ shows broad emission band from 700 to 1250 nm, which covers the first and second NIR windows. An NIR pc‐LED with radiant flux of 12.07 mW@350 mA is realized based on NaScGe2O6:Cr3+ and 450 nm blue LED chip. The ability of high‐power NIR light of the NIR pc‐LED to penetrate human tissues is observed successfully. Additionally, in NaScGe2O6:Cr3+, the luminescence performance of Cr3+ under 808 nm laser excitation is achieved for the first time.

This review investigates the thermal behaviors of phosphors and summarizes phosphors with excellent thermal stabilities.

A novel and direct transformation of aryl, heteroaryl, vinyl, or ethynyl methyl ketones or carbinols to corresponding primary amides has been developed. An iodine-NH(3).H(2)O system was proven to be efficient for this reaction and afforded the expected products with good yields in aqueous media. A tandem Lieben-Haller-Bauer reaction mechanism was involved in this type of reaction and is proposed for the first time.

Brucellosis is a neglected zoonosis. It causes acute febrile illness and a potentially debilitating chronic infection in humans, and livestock infection has substantial socioeconomic impact. Over the past two decades, improvements have been made to better understand the various aspects of human and animal brucellosis. Meanwhile, especially in the developing world, immense challenges that remain in controlling and eradicating brucellosis are novel diagnostics tools and efficacious vaccines. Here, we will focus on the remarkable issues on epidemiological survey, as well as the priority and challenge of brucellosis in China. Brucellosis will be controlled with meaningful collaboration between local and public partnerships effectively applying a One Health framework.
