A new regime for mechanical annealing and strong sample-size strengthening in body centred cubic molybdenum by Huang, Ling, Li, Qing-Jie, Shan, Zhi-Wei, Li, Ju, Ma, Evan, Sun, Jun, 1975-

“…In addition, there exists a critical diameter for focused ion beam milled pillars, below which the strengthening exponent increases dramatically, from ~0.3 to ~1. Thus, a new regime of size effects in BCC metals is discovered that converges to that of FCC metals, revealing deep connection in the dislocation dynamics of the two systems.…”

Granular shape memory ceramic packings by Yu, Hang, Hassani Gangaraj, Seyyed Mostafa, Du, Zehui, Gan, Chee Lip, Schuh, Christopher A

“…Specifically, (ZrO2)1-x-(CeO2)x is studied in three different composition regimes. In the shape memory regime (below the martensite finish temperature), confined uniaxial compression leads to martensite re-orientation in the granular SMC packing, with the peak intensity of preferred crystallographic orientation increasing with external loading. …”

Origin of residual strain in heteroepitaxial films by Postelnicu, Eveline, Wen, Rui-Tao, Ma, Danhao, Wang, Baoming, Wada, Kazumi, Michel, Jurgen, Kimerling, Lionel C

“…The model is expressed in terms of three regimes: (1) misfit control for the low temperature growth regime at 400 °C; (2) point defect control via annealing in the point defect recovery regime at 500–650 °C; and (3) thermal expansion control for growth or anneal at T &amp;gt; 650 °C in the dislocation recovery regime. …”

Photoemission Spectroscopy of Magnetic and Nonmagnetic Impurities on the Surface of the Bi[subscript 2]Se[subscript 3] Topological Insulator by Valla, T., Pan, Z. -H., Gardner, Dillon Richard, Lee, Young S., Chu, Shaoyan

“…We reveal a remarkable insensitivity of the topological surface state to both nonmagnetic and magnetic impurities in the low impurity concentration regime. Scattering channels open up with the emergence of hexagonal warping in the high-doping regime, irrespective of the impurity’s magnetic moment.…”

Diffusion-bonded CNT carpets for fundamental CDI studies by Enright, Ryan, Mitchell, R., Lv, C., Mutha, Heena K., Christiansen, Michael Gary, Thompson, Carl V., Wang, Evelyn N.

“…Unlike supercapacitors, CDI electrodes are required to operate in aqueous electrolytes with low ionic concentrations in a non-linear charging regime. To explore this practically and theoretically important regime, we developed robust, electrochemically-compatible carbon nanotube (CNT) carpet electrodes that posses a well-defined and uniform pore structure that is more readily analyzed in comparison to the random and multi-scale pore structure of typical carbon electrodes. …”

Mapping strain rate dependence of dislocation-defect interactions by atomistic simulations by Fan, Yue, Osetsky, Yuri N., Yip, Sidney, Yildiz, Bilge

“…Our predictions of a crossover from a defect recovery at the low strain-rate regime to defect absorption behavior in the high strain-rate regime are validated against our own independent, direct MD simulations at 10[superscript 5] to 10[superscript 7] s[superscript −1]. …”

Magneto-optical properties of InSb for infrared spectral filtering by Peard, Nolan, Callahan, Dennis, Perkinson, Joy C, Du, Qingyang, Patel, Neil S, Fakhrul, Takian, LeBlanc, John, Ross, Caroline A, Hu, Juejun, Wang, Christine Y

“…The Verdet coefficient was determined for a range of carrier concentrations near $10^{17}$ $\text{cm}^{-3}$ in the $\lambda$ = 8 $\mu$m - 12 $\mu$m long-wave infrared regime. The absorption coefficient was measured and a figure of merit calculated for each sample. …”

Liquid Copper and Iron Production from Chalcopyrite, in the Absence of Oxygen by Daehn, Katrin E., Stinn, Caspar, Rush, Lucas, Benderly-Kremen, Ethan, Wagner, Mary Elizabeth, Boury, Charles, Chmielowiec, Brian, Gutierrez, Carolina, Allanore, Antoine

“…However, unique opportunities to address urgent challenges faced by the copper industry arise by excluding oxygen and processing chalcopyrite in the native sulfide regime. Through electrochemical experiments and thermodynamic analysis, gaseous sulfur and electrochemical reduction in a molten sulfide electrolyte are shown to be effective levers to selectively extract the elements in chalcopyrite for the first time. …”
