  text: 'The highly enhanced thermoelectric figure of merit, zT ≈ 2.6 at 573 K, obtained
    recently in Cd-doped polycrystalline AgSbTe2 by Roychowdhury et al. ( Science
    2021, 371, 722) brings it to the forefront of thermoelectric and energy materials
    research. Ag/Sb cationic ordering in polycrystalline AgSbTe2 was a challenging
    issue for a long time: their ordered arrangement in the cationic sublattice in
    polycrystalline samples remained elusive despite multiple theoretical predictions
    and experimental studies. Recently, selective cation doping has been used to enhance
    the Ag/Sb ordering, and cation ordered nanoscale (2–4 nm) domains were observed
    in polycrystalline AgSbTe2, which reduce lattice thermal conductivity. The enhanced
    cation ordering also delocalizes disorder-induced localized electronic states,
    and consequently the electronic transport enhances. In this Focus Review, we provide
    the details of the rational design of a high-performance thermoelectric material
    using the recently developed atomic order–disorder optimization strategy with
    AgSbTe2 as an example. Atomic disorder is ubiquitous in most thermoelectric materials,
    and the atomic order–disorder optimization strategy applies to a large variety
    of thermoelectric materials.'

  text: Passivation layers on electrode materials are ubiquitous in nonaqueous battery
    chemistries and strongly govern performance and lifetime. They comprise breakdown
    products of the electrolyte including carbonate, alkyl carbonates, alkoxides,
    carboxylates, and polymers. Parasitic chemistry in metal–O2 batteries forms similar
    products and is tied to the deviation of the O2 balance from the ideal stoichiometry
    during formation/decomposition of alkaline peroxides or superoxides. Accurate
    and integral quantification of carbonaceous species and peroxides or superoxides
    in battery electrodes remains, however, elusive. We present a refined procedure
    to quantify them accurately and sensitively by pointing out and rectifying pitfalls
    of previous procedures. Carbonaceous compounds are differentiated into inorganic
    and organic ones. We combine mass and UV–vis spectrometry to quantify evolved
    O2 and complexed peroxide and CO2 evolved from carbonaceous compounds by acid
    treatment and Fenton’s reaction. The capabilities of the method are exemplified
    by means of Li–O2 and Na–O2 cathodes, graphite anodes, and LiNi0.8Co0.15Al0.05O2
    cathodes.
