Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

The Efficiency Question in Economics [PDF]

Philosophy of Science, 2018
AbstractMuch philosophical attention has been devoted to whether economic models explain and more generally to how scientific models represent. Yet there is an issue more practically important to economics than either of these, which I label theefficiency question: regardless of how exactly models represent, or of whether their role is explanatory or ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Economics notes: Definitions of efficiency

BMJ, 1999
This is the third in a series of occasional notes on economics Decision makers are increasingly faced with the challenge of reconciling growing demand for health care services with available funds.1 Economists argue that the achievement of (greater) efficiency from scarce resources should be a major criterion for priority setting.

Economic Efficiency, Distributive Justice and Liability Rules [PDF]

The main purpose of this paper is to show that the conflict between the considerations involving economic efficiency and those of distributive justice, in the context of assigning liability, is not as sharp as is generally believed to be the case.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

Advanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.
