Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

open access: yesAdvanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

FUNDAMENTAL MODELS OF STRUCTURAL STABILITY

open access: yesRudarsko-geološko-naftni Zbornik, 2017
In this paper, basic structural stability phenomena are described. After some general comments about stability in the field of civil engineering, four elementary sources of nonlinearity are mentioned: of equilibrium equations, strain (geometry) relations,

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Comparing various influences on adhesive contact with friction

open access: yesSelected Scientific Papers: Journal of Civil Engineering, 2019
A general computational model covering many types of frictional contact interfaces between visco-elastic bodies is considered for some cases physically relevant in numerical analysis of contact in civil engineering structures.

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

open access: yesAdvanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

La signalisation maritime en Tunisie (1881-1920) ou les phares de la présence coloniale

open access: yesRevue des Mondes Musulmans et de la Méditerranée, 2010
Two years after the landing of French troops in Tunisia, in 1883, the Plenipotentiary Paul Cambon appoints an Inspector General of Roads at the head of the Directorate of Civil engineering.

Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control

open access: yesAdvanced Materials, EarlyView.
Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.

Evaluation of Persian civil engineering equivalents Proposed by the Academy of Persian Language and Literature [PDF]

open access: yesزبان پژوهی
IntroductionTo strengthen the scientific register of Persian, selection of scientific terms from foreign languages and a precise understanding of word-formation mechanisms in this register and its capacities are of considerable importance.
