Drop impact on natural porous stones [PDF]

open access: yesJournal of Colloid and Interface Science, 2016
Drop impact and spreading on three natural porous stones are experimentally determined using high-speed imaging and compared with spreading over an impermeable steel surface. The dynamic non-wetting behavior during spreading and the hydrophobic contact angle >90° is attributed to the presence of an air layer between the droplet and the porous substrate.

Limitations of the Standard Procedure for the Evaluation of Marble and Limestone for Use in Construction: A Critical Analysis and Proposal for Modification [PDF]

open access: yes, 2011
The selection of natural stone for each specific use must be based on determinations which assess their technical quality and ensure their suitability for the environment in which they will be utilized. Among the criteria to be considered, a petrographic

Flux‐Regulated Crystallization of Perovskites Using Machine Learning‐Predicted Solvent Evaporation Rates for X‐Ray Detectors

open access: yesAdvanced Functional Materials, EarlyView.
By integrating machine learning into flux‐regulated crystallization (FRC), accurate prediction of solvent evaporation rates in real time, improving crystallization control and reducing crystal growth variability by over threefold, is achieved. This enhances the reproducibility and quality of perovskite single crystals, leading to reproducible ...

Near‐Infrared Organic Photovoltaic Electrodes for Subretinal Neurostimulation

open access: yesAdvanced Functional Materials, EarlyView.
Organic photovoltaic electrodes based on the D18:Y6 blend enable precise and light‐controlled activation of retinal ganglion cells in a degenerating retina. NIR Light‐driven activation of retinal ganglion cells, tunable stimulation parameters, and biocompatibility with human retinal organoids highlight their potential for next‐generation prosthetics ...

The RNA code: Nature’s Rosetta Stone [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
Marshall Nirenberg and Heinrich Matthaei initiated their biochemical approach to elucidating the genetic code in 1959, 6 years following the discovery of the double helix structure of DNA (1). At the time, geneticists were using T4 bacteriophage mutagenesis/reversion of plaque morphology toward the same goal by inferring that three mutations were ...

Naturalis Historia, Reconstructed [PDF]

open access: yes, 2013
When Pliny the Elder wrote Naturalis Historia around 70 A.D., the idea of natural history contained and connected biology, geology, and mineralogy with the history of painting and sculpture. Art was an extension of the natural world as its materials were

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles
