Red‐Light Tomographic Volumetric 3D Printing in Seconds for Fabrication of Colorless Structures

open access: yesAdvanced Materials Technologies, EarlyView.
A custom red‐light‐responsive TVAM platform combines methylene blue, triethanolamine, and PEGDA to fabricate transparent crosslinked hydrogels. Light patterns are projected into a rotating resin container, where a sacrificial photoinitiator system enables rapid polymerization and colorless channel‐containing structures, utilizing low‐energy light for ...

Response of gas exchange and chlorophyll fluorescence of maize to alternate irrigation with fresh- and brackish water

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
The scarcity of good-quality water is forcing the use of brackish water for irrigation in many areas around the world. Alternate fresh- and brackish water irrigation is a feasible irrigation method (IM).

Hexanoic acid 2-(diethylamino)ethyl ester enhances chilling tolerance in strawberry seedlings by impact on photosynthesis and antioxidants

open access: yesBiologia Plantarum, 2011
Strawberry (Fragaria ananassa Duch.) seedlings were pretreated with hexanoic acid 2-(diethylamino)ethyl ester (DA-6) in concentrations of 0, 10, 20 and 40 mg dm-3 and then subjected to chilling and rewarming. The effects of applied DA-6 on the generation

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

open access: yesAdvanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Transparent Single‐Dye NIR Photonic Platform for Multimodal Optical Authentication

open access: yesAdvanced Optical Materials, EarlyView.
A single‐component DHP‐SQ dye integrates visible transparency, near‐infrared (NIR) fluorescence, and photothermal functionality into one molecular platform. NIR‐selective visualization transforms visually imperceptible printed patterns into readily authenticated information, while screen‐printing compatibility enables well‐defined patterning on diverse

Arctic Micromonas uses protein pools and non-photochemical quenching to cope with temperature restrictions on Photosystem II protein turnover [PDF]

open access: yes, 2016
Micromonas strains of small prasinophyte green algae are found throughout the world’s oceans, exploiting widely different niches. We grew arctic and temperate strains of Micromonas and compared their susceptibilities to photoinactivation of Photosystem ...
