DOI: 10.1021/acs.inorgchem.1c01656
Abstract: SrAl2Si2 crystallizes into either a semimetallic, CaAl2Si2-type, α phase or a superconducting, BaZn2P2-type, β phase. We explore possible α→Pc,Tcβ transformations by employing pressure- and temperature-dependent free-energy calculations, vibrational spectral calculations, and room-temperature synchrotron powder X-ray… read more here.

DOI: 10.1038/s41522-017-0018-1
Abstract: The colonization of surfaces by bacterial biofilms constitutes a huge problem in healthcare and industry. When attempting biofilm inactivation or removal, it is crucial to sufficiently wet the biofilm surface with antibacterial agents; however, certain… read more here.

DOI: 10.1073/pnas.2205827119
Abstract: Significance Although bubble nucleation has been recognized as highly stochastic and heterogeneous, it is still poorly understood how surface nanoscopic topologies quantitatively modulate the nucleation process. Here, we directly measure single-bubble nucleation on surfaces with… read more here.

DOI: 10.1103/physrevb.100.045201
Abstract: Noncentrosymmetric metals such as Li$_2$(Pd$_{1-x}$Pt$_x$)$_3$B have different Fermi surface topology below and above the band touching point where spin-degeneracy is not lifted by the spin-orbit coupling. We investigate thermoelectric and optical response as probes for… read more here.

DOI: 10.1177/0954405421995618
Abstract: Unstable crude oil derivatives are among the main substances added to the mineral-based lubricants (MBL). However, the high purification and disposal costs of such lubricants and consequent environmental difficulties are the major drawbacks of cutting… read more here.
