pH‐Tunable Material Properties of Glycine‐Rich Condensates from Tick Bioadhesive

Advanced Functional Materials, EarlyView.
This work studies the influence of pH on the phase separation behavior of a disordered glycine‐rich protein found in tick bioadhesive. The results show profound impact on the propensity of coacervation, condensate microstructure and viscosity, amphiphilicity of the peptides, and effective encapsulation of therapeutic molecules.

Tailoring Microstructure in Copper‐Based Conductive Metal–Organic Frameworks for Enhanced Chemiresistive Sensing and Uptake of Sulfur Dioxide

Advanced Functional Materials, EarlyView.
Precursor‐ and solvent‐mediated synthesis yields four Cu3(HHTP)2 morphologies with distinct physicochemical, sorption, and sensing properties toward SO2. Uptake capacities correlate with BET surface area, while sensing performance scales with particle aspect ratio.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Multi‐Frequency SuperDARN HF Radar Observations of the Ionospheric Response to the October 2023 Annular Solar Eclipse

Geophysical Research Letters
An annular solar eclipse was visible on 14 October 2023 from 15:00–21:00 UT as its path traveled across North, Central, and South America. In this letter, we present the first multi‐frequency Super Dual Auroral Radar Network (SuperDARN) observations of ...

SOLAR-ECLIPSE OBSERVATIONS IN PAKISTAN: HEALTH AND SAFETY CONSIDERATIONS

The Sky, 2018
This paper addresses health issues associated with the observations of solar eclipses, in particular, eclipse retinopathy due to observation of partial-solar eclipses without proper protection to eyes.

OCTOID: A Soft Robotic System Featuring Programmable Shape Morphing and Dynamic Structural Coloration

Advanced Functional Materials, EarlyView.
Inspired by octopuses, actuating legs based on soft materials are fabricated with programmed chiroptical properties and mechanical behaviors to achieve dynamic color modulation and reversible shape morphing, and these legs are developed into a modular OCTOID system.

Otro eclipse de la poesía

Escuela Abierta, 2019
El autor compara el esplendor de la poesía y los poetas en el reinado de al-Mutamid de Sevilla y su posterior decadencia con "otro eclipse" -el del último cuarto de este siglo- en el que, según su opinión, la poesía no tiene el valor de antaño y los ...
