An empirical investigation of the effects of concentration on profitability among US banks [PDF]
This paper analyses the effects of concentration on profitability in the US banking sector from 1994-2005, using bank-level panel data. A new index of concentration is proposed, which reflects the depth and intensity of concentration.

Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

To profit or not to profit? That is the wrong question [PDF]
In social economy research, the issue of ‘profit’ (whether to make and/or distribute it) is a dominant framing concept. We argue that this dominance (even negatively referenced) maintains the hegemony of financial capital and the ‘for-profit’ paradigm. By refusing to accept a definition that labels organisations in terms of what they are not, scholars ...

Persistence of Profitability and the Dynamics of Competition in Turkey, 1985-2004 [PDF]
The existing empirical literature on the intensity of competition in developing countries shows that the persistence of profitability is smaller in developing than in advanced economies.

We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells
Indene‐C60 bisadduct (ICBA) accumulates at the buried interface of inverted tin‐lead perovskite solar cells, limiting undesired electron extraction while maintaining efficient hole transport. ICBA simultaneously scavenges molecular iodine, mitigating Sn2+ oxidation and interfacial recombination. This coupled electronic‐chemical regulation delivers 22.7%

A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...
