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.

Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations
Article describes how processes including hot compression, cold compression and subsequent annealing on the structures and properties are investigated and compared. They found that applying pressure up to 10 GPa at the glass transition temperature led to permanent densifications and a dramatic increase of elastic moduli by 90%, while thermal annealing reversed the increase and applying pressure at ambient temperature did not increase the modulus.

Novel 2D Dynamic Elasticity Maps for Inspection of Anisotropic Properties in Fused Deposition Modeling Objects
Article introducing a novel ultrasonic non-destructive and non-invasive elastography method demonstrated to evaluate the mechanical properties of fused deposition modeling 3D printed objects using two-dimensional dynamical elasticity mapping. Based on the recently investigated dynamic bulk modulus and effective density imaging technique, an angle-dependent dynamic shear modulus measurement was performed to extract the dynamic Young’s modulus distribution of the FDM structures. The elastographic image analysis demonstrated the presence of anisotropic dynamic shear modulus and dynamic Young’s modulus existing in the fused deposition modeling 3D printed objects. The non-destructive method also differentiated samples with high contrast property zones from that of low contrast property regions. The angle-dependent elasticity contrast behavior from the ultrasonic method was compared with conventional and static tensile tests characterization. A good correlation between the nondestructive technique and the tensile test measurements was observed.

Fabrication and characterization of inkjet-printed 2D perovskite optoelectronic devices
Article presents the large scale synthesis of solution-processed 2D (CH₃(CH₂)₃NH₃)₂(CH₃NH₃)ₙ − 1PbₙI₃ₙ + 1 (n = 2, 3, and 4) perovskites, a family of layered compounds with composition-tunable bandgap, where inkjet printing was used to fabricate heterostructure, flexible photodetector devices. The flexible, inkjet-printed perovskite 2D heterostructures have significant potential for optoelectronic devices, which can enable broad possibilities with compositional tunability and versatility of the organohalide perovskites.

A novel nano-particle strengthened titanium alloy with exceptional specific strength
This article microstructurally tailors an exceptionally high-strength titanium alloy, Ti-6Al-2Sn-4Zr-6Mo (Ti6246) through friction stir processing (FSP) in order to provide enhanced weight savings and improved fuel efficiency. The specific strength attained in one of the conditions is close to 450 MPa m³/mg, which is about 22% to 85% greater than any commercially available metallic material. This novel nano particle strengthened Ti alloy is a potential replacement for many structural alloys, enabling significant weight reduction opportunities.
