Improved out-of-plane properties through alternative print path and in-layer heating by Ole S. Nesheim, Anni Cao, Lisa Ducarouge, Christer W. Elverum

“…The primary increase in UTS was thus attributed to enhanced matrix bonding due to postheating, while the L toolpath effectively increased the tensile modulus. Based on matrix structure variations observed in the SEM images, we hypothesize that the initially porous structure solidifying after material deposition can be effectively eliminated by postheating, resulting in increased interlayer contact area, ultimately enhancing UTS.…”

USP1/UAF1 targets polyubiquitinated PCNA with an exo-cleavage mechanism that can temporarily enrich for monoubiquitinated PCNA by Niels Keijzer, Jan Sakoltchik, Kaustav Majumder, Nina van Lil, Farid El Oualid, Alexander Fish, Titia K. Sixma

“…Kinetic analysis reveals that USP1/UAF1 prefers cleaving the ubiquitin-ubiquitin bond over cleavage of the ubiquitin-PCNA bond and therefore treats poly- and monoubiquitinated PCNA as different substrates. A cryo-EM structure of USP1/UAF1 with a K63-diubiquitin and structure-based mutagenesis suggests that this mechanistic preference is maintained in evolution. …”

Performance Optimization and Synergistic Mechanism of Ternary Blended Cementitious System Composed of Fly Ash, Slag, and Recycled Micro-Powder by Rongfang Song, Qingnian Yang, Hang Song

“…SEM and mercury intrusion porosimetry (MIP) analyses revealed that systems incorporating low addition levels of recycled micro powder and slag powder exhibit calcium silicate hydrate (C-S-H) gel, acicular ettringite crystals, and a denser pore structure. However, at higher dosages (>10%), the porosity increases significantly and the pore structure deteriorates, resulting in reduced shrinkage performance. …”
