Development of durable “green” concrete exposed to deicing chemicals via synergistic use of locally available recycled materials and multi-scale modifiers [PDF]

open access: yes, 2018
From the economic and social perspectives, the use of waste materials would not be attractive until their costs and quality can satisfy the construction requirements.

Laser Engineering of HfN‐Based Nanoparticles for Safe NIR‐I Photothermal and X‐ray Enhancing Cancer Therapies

open access: yesAdvanced Functional Materials, EarlyView.
In this study, we produced HfN‐based nanoparticles via femtosecond laser ablation in acetone. The nanoparticles exhibit a red‐shifted plasmonic resonance in the NIR‐I window, colloidal stability after coating with polyethyleneglycol, and excellent biocompatibility. The photothermal and X‐ray sensitization therapeutic effects were demonstrated for tumor

Regeneration of thermally recycled glass fibre for cost effective composite recycling : the effect of fibre regeneration and matrix modification [PDF]

open access: yes, 2015
The recycling of glass fibre composites has become an important issue because of social-ecological, financial and legislative reasons. One main obstacle for the recycling of glass fibre composites is the low value of the recycled fibres.

Thermo‐Mechanically Recyclable Smart Textiles from Circularly Knitted Liquid Crystal Elastomer Fibers

open access: yesAdvanced Functional Materials, EarlyView.
Reprogrammable multi‐material smart textiles knitted from liquid crystal elastomer fibers undergo 2D and 3D deformation under thermal and photo stimuli. Circularly knitted tubular structures reversibly contract in radial and axial directions, enabling autonomous climbing, liquid release, and micro pumping.

Recovery and investigation of ITO coated-glass substrates from laboratory grade discarded perovskite solar cells for their sustainable reuse

open access: yesNext Materials
Perovskite solar cells (PSCs) have gained high popularity since their discovery in 2009. With the low-cost solution-based fabrication process, the power conversion efficiency (PCE) of PSCs has reached a remarkable 26.1 %.

Design & development of a novel house hold compressing device for a wheelie bin [PDF]

open access: yes, 2013
This project consists of researching, designing, developing, prototyping and testing a device that clamps onto a wheelie bin and easily compresses the waste inside.

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

On the functionality of vasa diatreta

open access: yesDissertationes Archaeologicae: Ex Instituto Archaeologico Universitatis de Rolando Eötvös Nominatae
This study re-evaluates the functionality and production context of Roman cage cups (vasa diatreta) through recently analysed fragments from Gorsium (Tác, Hungary), found in the apsidal audience hall of a Late Roman palace.

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...
