Surface Nanostructures Enhanced Biocompatibility and Osteoinductivity of laser-Additively Manufactured CoCrMo Alloys
Article describes how cobalt–chromium–molybdenum (CoCrMo) alloys are widely used in orthopedic implants due to their excellent corrosion and wear resistance and superior mechanical properties. In this study, the authors prepared CoCrMo alloys with surface nanostructures of various aspect ratios (AR) using laser-directed energy deposition (L-DED) and biocorrosion.

Multimodal and multiscale strengthening mechanisms in Al-Ni-Zr-Ti-Mn alloy processed by laser powder bed fusion additive manufacturing
Article describes how the unique thermokinetics of laser-powder bed fusion additive manufacturing has been exploited for development of a novel high strength Al-Ni-Ti-Zr-Mn alloy. The authors say that the addition of 0.5 wt% Mn leads to extraordinary improvement in ultimate tensile strength (502 MPa) and work hardening due to the activation of two Mn-induced strengthening mechanisms

Thermo/hydration responsive shape memory polymers with enhanced hydrophilicity for biomedical applications
Article states that thiol-ene/acrylate shape memory polymers (SMPs) have sufficient stiffness for facile insertion and precision placement and soften after exposure to physiological conditions to reduce the mechanical mismatch with body tissue; as a result, they have demonstrated excellent potential as substrates for various flexible bioelectronic devices, such as cochlear implants, nerve cuffs, cortical probes, plexus blankets, and spinal cord stimulators. Here, the authors report a new strategy for designing SMPs with enhanced shape recovery properties and lower moduli than previously reported SMPs under physiological conditions without sacrificing stiffness at room temperature by introducing a hydrophilic monomer.

Correlating work hardening with co-activation of stacking fault strengthening and transformation in a high entropy alloy using in-situ neutron diffraction
Article using in-situ neutron diffraction to correlate SF strengthening to work hardening behavior in a low SFE Fe40Mn20Cr15Co20Si5 (at%) high entropy alloy, SFE ~ 6.31 mJ m−2. Cooperative activation of multiple mechanisms was indicated by increases in SF strengthening and γ-f.c.c. → ε-h.c.p. transformation leading to a simultaneous increase in strength and ductility. The present study demonstrates the application of in-situ, neutron or X-ray, diffraction techniques to correlating SF strengthening to work hardening.

Insights into the mechanisms controlling the residual corrosion rate of borosilicate glasses
Article examining the glass durability and residual rate of borosilicate glass. The authors focus on the behavior of the soluble elements of the International Simple Glass (B, Na, and Ca) to show that the residual rate is controlled by the behavior of B, a glass former supposed to dissolve instantaneously when in contact with water and thus widely considered as an ideal tracer. The article demonstrates that B release is controlled by multiple processes highly dependent on the pH. A new paradigm, including B as a key element of the system, is proposed to develop a comprehensive model for the corrosion of borosilicate glass.

Cache-Aided General Linear Function Retrieval
This article designs a novel coded caching scheme that outperforms uncoded caching schemes that either use unicast transmissions or let each user recover all files in the library. It extends the scope of the authors’ past work that only considered the class of linear functions that operate element-wise over the files.
