Biochar aerogel-based electrocatalyst towards efficient oxygen evolution in acidic media (open access)

Biochar aerogel-based electrocatalyst towards efficient oxygen evolution in acidic media

Article argues that traditional acidic oxygen evolution reaction (OER) electrocatalysts are more prone to be oxidized and corroded as results of unstable carrier structures and variable electronic states of active species, so a high-performing biochar aerogel (BA) based electrocatalyst was realistically designed and synthetized via joint utilization of the terrestrial lignin and seaweed polysaccharide as carbon sources. This work puts forward a novel and effective strategy towards the enhancement of the acidic OER process by rational regulations of the BA and the coupling effect in micro-interface.

Branching of Titanium Nanorods (open access)

Branching of Titanium Nanorods

This article reports that Ti nanorod branching occurs at a low homologous temperature of 0.28 based on physical vapor deposition and characterizations using electron microscopy and X-ray diffraction. The insight into conditions for branching, together with the determination of the morphology and crystal orientation of the branches, lay the foundation for further studies of branching mechanisms and driving force.

Construction and characterization of superhydrophobic wood coatings using one-step technique (open access)

Construction and characterization of superhydrophobic wood coatings using one-step technique

Article describes how this study was aiming at enhancing the stain resistance and durability of varnish on wood surfaces, a super hydrophobic solution was created by blending the synthetic ZIF-8/paraffin with Hexadecyltrimethoxysilane at a specified mass ratio. This superhydrophobic mixture was then directly applied onto the wood varnish coating using a one-step method.

Highly Pseudocapacitive Storage Design Principles of Heteroatom-Doped Graphene anode in Calcium-Ion Batteries (open access)

Highly Pseudocapacitive Storage Design Principles of Heteroatom-Doped Graphene anode in Calcium-Ion Batteries

Article describes how pseudocapacitive storage of multivalent ions, especially Ca2+, in heteroatom-doped carbon nanomaterials is promising to achieve both high energy and power densities, but there is the lack of pseudocapacitive theories that enable rational design of the materials for calcium-ion batteries.

NextGen-Malloc: Giving Memory Allocator Its Own Room in the House (open access)

NextGen-Malloc: Giving Memory Allocator Its Own Room in the House

Article describes how memory allocation and management have a significant impact on performance and energy of modern applications. The authors observe that performance can vary by as much as 72% in some applications based on which memory allocator is used, and in this paper, the authors make a case for offloading memory allocation (and other similar management functions) from main processing cores to other processing units to boost performance, reduce energy consumption, and customize services to specific applications or application domains.
