As a most promising mid‐temperature thermoelectric material, CoSb3‐based bulk material exhibits an applicable figure‐of‐merit (ZT) of more than one. However, their fabrication is historically time‐consuming due to the long‐time solid‐state phase transitions from CoSb2 to CoSb3. To overcome this challenge, here, a fast one‐step process is developed to fabricate n‐type Yb‐doped CoSb3 with stable ZT of 1.12 at 765 K in <5 h. Experiments confirm Yb promotes peritectic reactions of CoSb + Liquid → CoSb2 and CoSb2 + Liquid → CoSb3, optimizes power factor, and suppresses thermal conductivity. Moreover, the dense grains, induced by the one‐step crystallization, result in outstanding mechanical properties with a Young's modulus of 171.4 GPa and a hardness of 8.8 GPa in the Yb‐doped CoSb3. This study indicates that the fast one‐step fabrication route can effectively promote the practical applications of CoSb3‐based thermoelectrics and provide guidance for thermoelectric fabrication via rational phase design.

Realizing high thermoelectric performance in CoSb3 skutterudite‐based thin films and their devices is historically challenging, especially due to the lack of high‐performing thin‐film‐based device working at medium‐to‐high temperatures. Here, a record‐high ZT of 1.1 is achieved at 683 K in an n‐type Ce0.3Ni1.5Co2.5Sb12 thin film, fabricated from a self‐designed target via advanced pulsed laser deposition. Both experimental and computational results confirm that the Ce‐filling and metal‐featured nanoinclusions such as CeSb contribute to high electrical conductivity, while the Ni‐doping and significantly strengthen the energy filtering effect that occurs at the dense interfaces between the Ce0.3Ni1.5Co2.5Sb12 matrix and the nanoinclusions which leads to a large Seebeck coefficient, giving rise to such a high ZT. In addition, a new‐type CoSb3 thin‐film‐based device is successfully fabricated, which exhibits a high output power density of 8.25 mW cm−2 at a temperature difference of 140 K and a cold‐side temperature of 573 K, indicating the potential for application to medium‐to‐high‐temperature power generation scenarios.

Brigatinib is a next‐generation anaplastic lymphoma kinase (ALK) inhibitor approved for the treatment of patients with ALK‐positive (ALK+) non–small cell lung cancer (NSCLC). A phase 1 drug‐drug interaction study was conducted to evaluate the effect of multiple‐dose administration of brigatinib on the single‐dose pharmacokinetics of midazolam, a sensitive cytochrome P450 3A substrate. In cycle 1, patients with ALK+ or ROS1+ solid tumors, including NSCLC, received a single 3‐mg dose of midazolam as an oral solution alone on day 1 and then coadministered with brigatinib on day 21 (brigatinib 90 mg once daily on days 2‐8; 180 mg once daily on days 9‐28). After cycle 1, patients could continue to receive brigatinib in 28‐day treatment cycles. The primary study objective was to characterize the effect of brigatinib 180 mg once daily on midazolam pharmacokinetics. The secondary objective was to assess safety. Exploratory efficacy endpoints included objective response rate and progression‐free survival. Brigatinib was generally well tolerated, and safety data were consistent with the known safety profile. Among the 10 patients with ALK+ NSCLC, the confirmed objective response rate was 30% and median progression‐free survival was 7.2 months. Coadministration of brigatinib reduced midazolam maximum observed plasma concentration by ≈16% (geometric least‐squares mean ratio, 0.836 [90%CI, 0.662‐1.056]) and area under the plasma concentration–time curve from time 0 to infinity by ≈26% (geometric least‐squares mean ratio, 0.741 [90%CI, 0.600‐0.915]). Thus, brigatinib is a weak inducer of cytochrome P450 3A in vivo. [ABSTRACT FROM AUTHOR]

This study examined various parental racial socialization messages as mediators between school‐based racial discrimination and racial identity formation over 4 years for African American boys (N = 639) and African American girls (N = 711). Findings indicated that school‐based racial discrimination was associated with racial identity beliefs. For African American boys, behavioral racial socialization messages mediated the relation between school‐based racial discrimination and racial centrality over time. Mediation also resulted for African American girls, but for a different set of race‐related messages (negative messages and racial barriers) and racial identity beliefs. The developmental significance of the findings and implications for future research are discussed. [ABSTRACT FROM AUTHOR]
