Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Ekonomikos samprata, ekonominės politikos ribos ir dimensijos

open access: yesEkonomika, 2003
Dabar yra plačiai paplitusi tvarios (sustainable) ekonominės plėtros sąvoka. Ji suponuoja, kad galima ir netvari (unsustainable) ekonominė plėtra. Viena į galimos netvarios ekonominės plėtros priežasčių – jos nesubalansuotumas, kuris, be kitų, gali ...

Gold Nanoclusters as Dual Agents for Engineering Tumor Vascular Leakiness and Performing Photothermal Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Many cancer nanotherapeutics, while potent, suffer from the inability to escape from the tumor vasculature, especially in the absence of endothelial permeability. In this work, ultrasmall gold nanoclusters could engineer nanomaterials induced endothelial leakiness (NanoEL) and harness strong NIR induced photothermal characteristics to suppress tumor ...

Quadratic deformation of Minkowski space [PDF]

open access: yes, 2012
We present a deformation of the Minkowski space as embedded into the conformal space (in the formalism of twistors) based in the quantum versions of the corresponding kinematic groups.

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...
