The Role of the Surface Energy of Tannin‐Based Adsorbent Materials on the Lead Removal Capacity in Contaminated Water

open access: yesChemistry–Methods, EarlyView.
Sample with low concentration of surface groups presents low surface energy and in consequence low adsorption capacity independently of the specific surface area and micro and mesoporosity. In this work, inverse gas chromatography at infinite dilution was used to associate the surface properties (London component, acid and basic constants, and enthalpy)

Effect of pre-aging deformation on the intergranular corrosion resistance of 6000 series aluminium alloys [PDF]

open access: yesMATEC Web of Conferences, 2020
Aluminium alloys in the 6000 series may become susceptible to intergranular corrosion (IGC) by unfavourable thermomechanical processing in combination with presence of Cu and a low Mg/Si ratio.

Phylogenetic analysis of paired breast carcinomas identifies genetic events associated with clonal recurrence and invasive progression

open access: yesThe Journal of Pathology, EarlyView.
Abstract Development of ipsilateral breast carcinoma following a diagnosis of breast ductal carcinoma in situ (DCIS) has been assumed to represent recurrence of the primary tumour. However, this may not always be the case, and it is important to determine how often such recurrences represent new tumours.

Conservation challenges and opportunities for native apple (Malus) species in Canada

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Boron and Nitrogen Bridged Mn Single‐Atom Catalyst for Highly Efficient Nitrogen Electroreduction to Ammonia

open access: yesSmall, EarlyView.
This work demonstrates a Mn single‐atom catalyst coordinated with B2N2 in B/N co‐doped carbon (MnB2N2/C) as an efficient platform for electrochemical NH3 synthesis. The MnB2N2 configuration lowers the energy barrier for N2 protonation while suppressing hydrogen evolution, achieving remarkably high NH3 Faradaic efficiency and long‐term durability.

METAL ANOMALY PROSPECTION AT CERRADO. EXAMPLE FOR THE USE OF SI-PHYTOLITHS AT RIACHO DOS MACHADO REGION, MINAS GERAIS, BRAZIL.

open access: yesGeochimica Brasiliensis, 2018
The target area of this work is a heavy metal anomaly in the surroundings of a gold mine and a lead mining complex. This work investigated the distribution of selected heavy elements in soil samples and Si-Phytoliths from plants. The aim was to verify if

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

open access: yessteel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Information systems and digitization of traditional knowledge: Trends in cultural heritage and memory institutions and the WIPO Genetic Resources Treaty*

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract Understanding the role of information communication technologies (ICTs) in development, especially in relation to marginalized populations, has been the focus of many related disciplinary categories within the broader ecosystem of information sciences.
