Wavelength‐Dependent Differential Amplification of Raman Scattering by Chiral Gold Nanorods for Multiplexed Encoding

open access: yesAdvanced Functional Materials, EarlyView.
The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...

Resistance Exercise Intervention Restores Functional Capacity and Improves Frailty Biomarkers in Centenarians. [PDF]

open access: yesJ Cachexia Sarcopenia Muscle
ABSTRACT Background Centenarians comprise an age group characterized by exceptional longevity and low age‐associated pathologies. However, they still experience physiological decline, and different studies have linked frailty to this population. Exercise interventions reverse frailty and improve functional capacity, but no studies have addressed the ...

Selective Laser Sintering 3D Printing of Drug‐Loaded Intravitreal Implants

open access: yesAdvanced Functional Materials, EarlyView.
Selective laser sintering enables the fabrication of biodegradable and biocompatible intravitreal implants with tunable microstructures for sustained drug delivery. By modulating laser scanning speed, the polymer matrix architecture is engineered to control the release kinetics of dexamethasone and riboflavin over several months. This approach offers a

Structural Control of Photoconductivity in a Flexible Titanium‐Organic Framework

open access: yesAdvanced Materials, EarlyView.
The concept of flexibility is extended to titanium frameworks and use it to gain control over charge transport. MUV‐35 is a flexible doubly interpenetrated framework that can shrink spontaneously its volume by ≈40% to afford a photoconductive, porous state that is thermodynamically favored by non‐covalent interactions. Abstract The soft nature of Metal‐

Bi‐Functional Topospecific Nanoparticles to Promote Immune‐Tumor Cell Engagement as A New Immunotherapeutic Strategy

open access: yesAdvanced Materials, EarlyView.
A Janus‐engineered nanoplatform (J‐pHLIP‐PD1), featuring separate tumor‐ and immune‐targeting faces, bridges melanoma cells and cytotoxic T lymphocytes using toposelective pHLIP and anti‐PD‐1 presentation. This strategy elicits robust antitumor responses, promotes immunogenic tumor cell death, suppresses lung metastasis in vivo, and provides a modular,

Cultura contra cultura

open access: yesTripodos, 2008
De totes les grans paraules, és a dir, de tots els vocables destinats a la confusió, cultura és amb força probabilitat la que ha sofert les més grans expropiacions. Procedent del mot llatí cultus, participi de colere, va designar en primer lloc el conreu de la terra, i amb el concepte de cultura animi de Ciceró es va obrir al conreu de l’esperit, al ...

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Differential serotonergic modulation of two types of aggression in weakly electric fish

open access: yesFrontiers in Behavioral Neuroscience, 2012
Agonistic aggression has provided an excellent framework to study how conserved circuits and neurochemical mediators control species-specific and context-dependent behavior.
