text: 'We consider Markov decision processes (MDPs) with specifications given as
Büchi (liveness) objectives, and examine the problem of computing the set of almost-sure
winning vertices such that the objective can be ensured with probability 1 from
these vertices. We study for the first time the average-case complexity of the
classical algorithm for computing the set of almost-sure winning vertices for
MDPs with Büchi objectives. Our contributions are as follows: First, we show that
for MDPs with constant out-degree the expected number of iterations is at most
logarithmic and the average-case running time is linear (as compared to the worst-case
linear number of iterations and quadratic time complexity). Second, for the average-case
analysis over all MDPs we show that the expected number of iterations is constant
and the average-case running time is linear (again as compared to the worst-case
linear number of iterations and quadratic time complexity). Finally we also show
that when all MDPs are equally likely, the probability that the classical algorithm
requires more than a constant number of iterations is exponentially small.'

text: 'We consider the problem of deciding whether the persistent homology group
of a simplicial pair (K,L) can be realized as the homology H∗(X) of some complex
X with L ⊂ X ⊂ K. We show that this problem is NP-complete even if K is embedded
in double-struck R3. As a consequence, we show that it is NP-hard to simplify
level and sublevel sets of scalar functions on double-struck S3 within a given
tolerance constraint. This problem has relevance to the visualization of medical
images by isosurfaces. We also show an implication to the theory of well groups
of scalar functions: not every well group can be realized by some level set, and
deciding whether a well group can be realized is NP-hard.'

text: 'We present a hybrid intercalation battery based on a sodium/magnesium (Na/Mg)
dual salt electrolyte, metallic magnesium anode, and a cathode based on FeS2 nanocrystals
(NCs). Compared to lithium or sodium, metallic magnesium anode is safer due to
dendrite-free electroplating and offers extremely high volumetric (3833 mAh cm-3)
and gravimetric capacities (2205 mAh g-1). Na-ion cathodes, FeS2 NCs in the present
study, may serve as attractive alternatives to Mg-ion cathodes due to the higher
voltage of operation and fast, highly reversible insertion of Na-ions. In this
proof-of-concept study, electrochemical cycling of the Na/Mg hybrid battery was
characterized by high rate capability, high Coulombic efficiency of 99.8%, and
high energy density. In particular, with an average discharge voltage of ∼1.1
V and a cathodic capacity of 189 mAh g-1 at a current of 200 mA g-1, the presented
Mg/FeS2 hybrid battery delivers energy densities of up to 210 Wh kg-1, comparable
to commercial Li-ion batteries and approximately twice as high as state-of-the-art
Mg-ion batteries based on Mo6S8 cathodes. Further significant gains in the energy
density are expected from the development of Na/Mg electrolytes with a broader
electrochemical stability window. Fully based on Earth-abundant elements, hybrid
Na-Mg batteries are highly promising for large-scale stationary energy storage. '

text: 'A simple and effective method to introduce precise amounts of doping in nanomaterials
produced from the bottom-up assembly of colloidal nanoparticles (NPs) is described.
The procedure takes advantage of a ligand displacement step to incorporate controlled
concentrations of halide ions while removing carboxylic acids from the NP surface.
Upon consolidation of the NPs into dense pellets, halide ions diffuse within the
crystal structure, doping the anion sublattice and achieving n-type electrical
doping. Through the characterization of the thermoelectric properties of nanocrystalline
PbS, we demonstrate this strategy to be effective to control charge transport
properties on thermoelectric nanomaterials assembled from NP building blocks.
This approach is subsequently extended to PbTexSe1-x@PbS core-shell NPs, where
a significant enhancement of the thermoelectric figure of merit is achieved. '

text: 'A cation exchange-based route was used to produce Cu2ZnSnS4 (CZTS)-Ag2S nanoparticles
with controlled composition. We report a detailed study of the formation of such
CZTS-Ag2S nanoheterostructures and of their photocatalytic properties. When compared
to pure CZTS, the use of nanoscale p-n heterostructures as light absorbers for
photocatalytic water splitting provides superior photocurrents. We associate this
experimental fact to a higher separation efficiency of the photogenerated electron-hole
pairs. We believe this and other type-II nanoheterostructures will open the door
to the use of CZTS, with excellent light absorption properties and made of abundant
and environmental friendly elements, to the field of photocatalysis. '

text: 'Monodisperse Pd2Sn nanorods with tuned size and aspect ratio were prepared
by co-reduction of metal salts in the presence of trioctylphosphine, amine, and
chloride ions. Asymmetric Pd2Sn nanostructures were achieved by the selective
desorption of a surfactant mediated by chlorine ions. A preliminary evaluation
of the geometry influence on catalytic properties evidenced Pd2Sn nanorods to
have improved catalytic performance. In view of these results, Pd2Sn nanorods
were also evaluated for water denitration. '

text: 'We consider two-player zero-sum games on graphs. These games can be classified
on the basis of the information of the players and on the mode of interaction
between them. On the basis of information the classification is as follows: (a)
partial-observation (both players have partial view of the game); (b) one-sided
complete-observation (one player has complete observation); and (c) complete-observation
(both players have complete view of the game). On the basis of mode of interaction
we have the following classification: (a) concurrent (both players interact simultaneously);
and (b) turn-based (both players interact in turn). The two sources of randomness
in these games are randomness in transition function and randomness in strategies.
In general, randomized strategies are more powerful than deterministic strategies,
and randomness in transitions gives more general classes of games. In this work
we present a complete characterization for the classes of games where randomness
is not helpful in: (a) the transition function probabilistic transition can be
simulated by deterministic transition); and (b) strategies (pure strategies are
as powerful as randomized strategies). As consequence of our characterization
we obtain new undecidability results for these games. '

text: A cation exchange-based route was used to produce Cu2ZnSnS4 (CZTS)-Ag2S nanoparticles
with controlled composition. We report a detailed study of the formation of such
CZTS-Ag2S nanoheterostructures and of their photocatalytic properties. When compared
to pure CZTS, the use of nanoscale p-n heterostructures as light absorbers for
photocatalytic water splitting provides superior photocurrents. We associate this
experimental fact to a higher separation efficiency of the photogenerated electron-hole
pairs. We believe this and other type-II nanoheterostructures will open the door
to the use of CZTS, with excellent light absorption properties and made of abundant
and environmental friendly elements, to the field of photocatalysis.

text: We report the synthesis and photocatalytic and magnetic characterization of
colloidal nanoheterostructures formed by combining a Pt-based magnetic metal alloy
(PtCo, PtNi) with Cu2ZnSnS4 (CZTS). While CZTS is one of the main candidate materials
for solar energy conversion, the introduction of a Pt-based alloy on its surface
strongly influences its chemical and electronic properties, ultimately determining
its functionality. In this regard, up to a 15-fold increase of the photocatalytic
hydrogen evolution activity was obtained with CZTS–PtCo when compared with CZTS.
Furthermore, two times higher hydrogen evolution rates were obtained for CZTS–PtCo
when compared with CZTS–Pt, in spite of the lower precious metal loading of the
former. Besides, the magnetic properties of the PtCo nanoparticles attached to
the CZTS nanocrystals were retained in the heterostructures, which could facilitate
catalyst purification and recovery for its posterior recycling and/or reutilization.
