This study applies several high impact practices in an integrated fourth-year biomedical engineering course. The engineering design project is mapped to six deliverables using an adaptation of the Information Rich Engineering Design (IRED) model. This pedagogy facilitates regular student interactions with the instructor, the teaching assistant, the librarian and peers. Periodic information audits provide students with opportunities to reflect, integrate their learning, and share diverse experiences with the instructor. The term project is a real-world application which allows students to discover the relevance of theoretically learned concepts to hands-on problem solving. Students demonstrate competence in skills related to information seeking, writing and critical thinking through the completion of an IEEEstyle conference paper.

Background: Injectable platelet-rich fibrin (i-PRF) has the capacity to release great amounts of several growth factors, as well as to stimulate increased fibroblast migration and the expression of collagen, transforming growth factor β, and platelet-derived growth factor. Consequently, i-PRF can be used as a bioactive agent to promote periodontal tissue regeneration.
Objective: We aim to compare and evaluate the effectiveness of i-PRF in periodontal tissue regeneration.

Meteoritic impacts on planetary surfaces deliver a significant amount of energy that can produce prebiotic organic compounds such as cyanides, which may be a key step to the formation of biomolecules. To study the chemical processes of impact-induced organic synthesis, we simulated the physicochemical processes of hypervelocity impacts (HVI) in experiments with both high-speed C projectiles and laser ablation. In the first approach, a C beam was accelerated to collide with ammonium nitrate (NHNO) to reproduce the shock process and plume generation of meteoritic impacts on nitrogen-rich planetary surfaces.

A NaF-rich composite artificial interphase is generated relying on a simple chemical reaction by regulating methyl 2,2,2-trifluoromethyl ester reactivity, which can promote rapid ion transport and effectively inhibit dendrite growth in carbonate electrolytes. The assembled NaF@Na‖NaV(PO) full cell attains a long lifespan of 4000 cycles at 5C with 95% capacity retention, and a high specific capacity of 80.8 mAh g at 30C.

Voice quality serves as a rich source of information about speakers, providing listeners with impressions of identity, emotional state, age, sex, reproductive fitness, and other biologically and socially salient characteristics. Understanding how this information is transmitted, accessed, and exploited requires knowledge of the psychoacoustic dimensions along which voices vary, an area that remains largely unexplored. Recent studies of English speakers have shown that two factors related to speaker size and arousal consistently emerge as the most important determinants of quality, regardless of who is speaking.

Layered transition metal oxides (LTMOs) are attractive cathode candidates for rechargeable secondary batteries because of their high theoretical capacity. Unfortunately, LTMOs suffer from severe capacity attenuation, voltage decay, and sluggish kinetics, resulting from irreversible lattice oxygen evolution and unstable cathode-electrolyte interface. Besides, LTMOs accumulate surface residual alkali species, like hydroxides and carbonates, during synthesis, limiting their practical application.
