Impurity Band Formation as a Route to Thermoelectric Power Factor Enhancement in n‐type XNiSn Half‐Heuslers

open access: yesAdvanced Physics Research, EarlyView.
A new route to improve the power factor of n‐type XNiSn half‐Heusler thermoelectrics is demonstrated. This relies on the alignment of host and impurity bands arising from Cu dopants. The effect is strongest near room temperature and substantially improves the performance.

Exploring developmental changes in femoral midneck cross‐sectional properties

open access: yesThe Anatomical Record, EarlyView.
The properties of femoral midneck cross‐sections exhibit a unique growth pattern that is characterized by shape changes during adolescence. Abstract This research delves deeper into previous works on femoral cross‐sectional properties during ontogeny by focusing for the first time on the human femoral midneck. The ontogenetic pattern of cross‐sectional

The local period integrals and essential vectors

open access: yesMathematische Nachrichten, Volume 296, Issue 1, Page 339-367, January 2023., 2023
Abstract By applying the formula for essential Whittaker functions established by Matringe and Miyauchi, we study five integral representations for irreducible admissible generic representations of GLn over p‐adic fields. In each case, we show that the integrals achieve local formal L‐functions defined by Langlands parameters, when the test vector is ...

Aging Behavior Beyond SOH 80: An Experimental Aging Study on Commercial Lithium–Ion Batteries with Different Cathode Materials: Capacity Loss, Resistance Change and Impedance Modeling

open access: yesBatteries &Supercaps, EarlyView.
Commercial cells made of four different cathode materials are studied for two modes of degradation and subsequently characterized with three different diagnostic techniques during and after aging, leading to a total of more than 200 cells analyzed for this study. Thus, this study reveals aging effects for lithium–ion batteries beyond state of health of
