Polymeric Layered Films for TiO2‐Au/CuS Tandem Photothermal Catalytic H2 Production in Harsh Seawater and Waste Plastic Media

open access: yesAdvanced Energy Materials, EarlyView.
A spatially decoupled, polymeric passivated catalytic system is designed to facilitate pivotal photoprocesses such as photothermal, photogeneration‐charge separation, and redox at distinct locations. The proposed polymeric tandem photothermal catalytic (PTPC) film consists of TiO2/Au photocatalytic and CuS photothermal layers, spatially separated and ...

Overload breakdown in models for photosynthesis [PDF]

open access: yesarXiv, 2015
In many models of the Calvin cycle of photosynthesis it is observed that there are solutions where concentrations of key substances belonging to the cycle tend to zero at late times, a phenomenon known as overload breakdown. In this paper we prove theorems about the existence and non-existence of solutions of this type and obtain information on which ...

Photosynthesis and Respiration [PDF]

open access: yes
Most people are aware that plants undergo photosynthesis, a process by which they convert sunlight and carbon dioxide in sugar and water. But not as many realize that plants also undergo respiration, which is the reverse of this process.

Early evolution of purple retinal pigments on Earth and implications for exoplanet biosignatures

open access: yes, 2018
We propose that retinal-based phototrophy arose early in the evolution of life on Earth, profoundly impacting the development of photosynthesis and creating implications for the search for life beyond our planet.

Cd Single Atom as an Electron Mediator in an S‐Scheme Heterojunction for Artificial Photosynthesis of H2O2

open access: yesAdvanced Energy Materials, EarlyView.
To achieve precise coupling between two semiconductors with a charge shuttle and interfacial interaction modulation, a catalyst architecture with a Cd single atom mediated S‐scheme heterojunction formed by interfacing CdS and TiO2 nanoparticles is proposed.
