Omnidirectional underwater surveying and telepresence [PDF]

open access: yes, 2016
Exploratory dives are traditionally the first step for marine scientists to acquire information on a previously unknown area of scientific interest. Manned submersibles have been the platform of choice for such exploration, as they allow a high level ...

Expanded Scorpionate and Siderophore‐Inspired Ligands: From Foundational Designs to Modern Applications

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The concept of scorpionate ligands has evolved significantly since the introduction of tris(pyrazolyl)borate. By integrating a biological supramolecular ligand scaffold with the classic scorpionate architecture, researchers have made notable strides in mimicking the active sites of nitrogenase and advancing homogeneous catalysis.

Ligand‐Level Chemical Activation: Coordination with Benefits

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
While often perceived as a liability, ligand‐based reactivity in carefully designed settings becomes a powerful synthetic tool. The key to streamlined processes overriding classical ionic reactivity is the selective electron redistribution induced by metal coordination. This enables storage of electrons and protons or incorporation of functional groups

Etch mechanism of an Al₂O₃ hard mask in the Bosch process

open access: yes, 2022
The etching of high aspect ratio structures in silicon via the Bosch process is essential in modern technologies such as microelectromechanical systems (MEMS) and through‑silicon vias (TSV) fabrication. The process can be very demanding on the mask selectivity due to long etching times, and it has been shown that an Al2O3 hard mask is very suitable in ...

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Poststroke epilepsy is associated with vascular cognitive disorder in young stroke patients: The ODYSSEY study

open access: yesEpilepsia, EarlyView.
Abstract Objective Cognitive disorder is common after stroke at a young age, especially in patients with poststroke epilepsy (PSE). Whether the causative mechanism is direct (due to epilepsy‐related network alterations) or indirect (due to effect‐modifiers such as stroke severity) is not fully understood.

Phenolic Profiles, Antioxidant Properties and Predicted Glycaemic Index of Bread Sweetened With Date Syrup in Comparison With Granulated Sugar

open access: yesFood Chemistry International, EarlyView.
Date syrup are used as sweetener in bread. Bread with date syrup had superior phenolic composition, better antioxidant properties and carbohydrate hydrolysing enzymes while bread with granulated sugar had higher predicted glyceamic index. The study concluded that date syrup could be the next though‐out ingredient for dual purpose in bread. ABSTRACT The

ULK4 and CDKN2A polymorphisms influence the risk of developing monoclonal gammopathy of undetermined significance

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Monoclonal gammopathy of undetermined significance (MGUS) is an asymptomatic precursor to multiple myeloma, sharing substantial genetic features with overt malignancy. Given evidence implicating autophagy in myeloma risk, this study examined whether genetic variations in autophagy‐related genes influence MGUS susceptibility.
