Effects of motor patterns on water-soluble and membrane proteins and cholinesterase activity in subcellular fractions of rat brain tissue [PDF]

open access: yes
Albino rats were kept for a year under conditions of daily motor load or constant hypokinesia. An increase in motor activity results in a rise in the acetylcholinesterase activity determined in the synaptosomal and purified mitochondrial fractions while ...

From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Areas of daily mobility

open access: yes, 2000
La mobilité quotidienne connaît, depuis une trentaine d’années en France, une évolution principalement géographique. Les bassins de vie débordent largement des limites de la ville morphologique et la commune est loin de constituer l’enveloppe de la vie quotidienne de ses habitants.

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

open access: yesAdvanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

open access: yesAdvanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

Compulsory elements in daily personal mobilities

open access: yesNetcom
This article explores the nature of compulsory elements within daily mobilities that seemingly present freedom and personal autonomy, notably in the ability of individuals to choose among several mobility modes and technological vehicles for these movements.

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

ANALYSIS OF THE DAILY MOBILITY IN FLORIANÓPOLIS

open access: yesGeo UERJ, 2020
O conceito de mobilidade é polissêmico e pode ser adjetivado para dar providência a diferentes explicações, dentre as quais destaca-se a mobilidade cotidiana, compreendida como aquela do trajeto de casa ao trabalho e vice-versa, cujas implicações forjam hábitos e práticas espaciais.
