Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

Advanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Chlorination‐Enabled Oxygen Control and Dual‐Sulfur Source Aided Trap Passivation to Unlock 8.24% Efficient Sb2S3 Photovoltaic Devices

Advanced Functional Materials, EarlyView.
This work demonstrates a scalable, low‐temperature synthesis strategy that combines a thioacetamide (TA)‐based dual sulfur source with CdS chlorination, enabling the formation of high‐quality Sb2S3 with a reduced open‐circuit voltage loss, resulting in improved device efficiency.

Phase Evolution Kinetics in Additive‐Free 19.75% Organic Photovoltaics Empowered by Solvent Vapor Annealing

Advanced Functional Materials, EarlyView.
Solvent vapor annealing enables kinetic control of additive‐free morphology in organic solar cells. Selective plasticization of acceptor forms an optimal fibrillar network, boosting efficiency to 19.06% (binary) and 19.75% (ternary), with ultrafast exciton dissociation and reduced recombination.

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Efficient Searches for Small Signals across Two-channel Noisy Data: A Challenge in Big-data Observations

The Astrophysical Journal Supplement Series
Searching for novel small signals in noisy data is preferably pursued by correlation in two or more independently operating channels. Signals of potential interest exist in tails beyond κσ , where κ denotes a multiple of the standard deviation σ of the ...
