Ductility Tuning via Cluster Network Characteristics of Porous Components

open access: yesAdvanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

A Study of the Effects of Ionic Charge and Molecular Weight of Polymers on Wet-Web Strength [PDF]

open access: yes, 1978
Improved machine speeds in the production of paper have increased the number of wet-end breaks due to wet-webs that are unable to withstand the increased stresses at increased rates of production.

Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact

open access: yesAdvanced Materials Technologies, EarlyView.
This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across

Mechanical characterization of adobe bricks in existing constructions in Aveiro Region, Portugal [PDF]

open access: yes, 2005
In Portugal it is common to find earth constructions all over the country, being predominant in the centre and south. In the past, earth was massified as a construction material, used with different typologies and applications.

Exciton Radiative Lifetimes in Hexagonal Diamond Ge and SixGe1–x Alloys

open access: yesAdvanced Optical Materials, EarlyView.
Strong room‐temperature photoluminescence reported in hexagonal Ge conflicts with theory predicting a nearly dark band edge. First‐principles calculations of excitonic radiative lifetimes fill a key gap in this debate, showing that pristine hexagonal Ge remains intrinsically weakly emissive, while Si alloying only modestly shortens the lifetime and ...

Investigating Fatigue Performance on the Foamed Asphalt Specimens Generated Using Different Foam Properties [PDF]

open access: yes, 2012
An evaluation of fatigue resistance for foamed asphalt mixture is very demanding since the binder is not continuously distributed on the aggregate surface and this mixtures contains water, the content of which dramatically affects the mechanical ...

The Role of Ionic Liquids at the Biological Interfaces in Bioelectronics

open access: yesAdvanced Science, EarlyView.
Ionic liquids (ILs) are highlighted as key artificial ionic materials that bridge biological ion‐based signaling and electronic devices. By understanding their composition, structure, function relationships, and mechanisms, ILs can advance from high performance electrolyte to core materials enabling integrated, multifunctional bioelectronics for ...

MODELING THE DIRECT TENSILE STRENGTH FOR LIGNITE EXTRACTED AT U.M.C. PESTEANA USING THE FINITE-DISCRETE ELEMENT METHOD (FDEM) [PDF]

open access: yesFiabilitate şi Durabilitate
In rock mechanics labs, the tensile strength test is carried out by either direct or indirect methods. Among indirect test methods, the most common is a diametrical compression on a disk specimen, also known as the Brazilian Tensile Strength (BTS) test.
