Human behavior occurs within a system, and as such, so do behaviors in performance-related domains (e.g., athletics, academics). Doping is a performance enhancement behavior that can be problematic because of the negative physical and psychological effects associated with the use of some substances and the common argument that doping is unfair. However, doping continues and may be increasing. Because a firm theoretical or empirical understanding of doping does not exist, this article proposes a conceptual, comprehensive, and innovative systemic model of doping behavior. The model is built from relevant empiricism supporting the idea that contemporary doping behavior is a function of systemic transactions between historical doping practices, the present environment, current antidoping interventions, one's genetic makeup, developmental milestones, social factors, and epigenetics.

Dynamic micro/nano-structured surfaces play pivotal roles in biological systems and engineering applications. Despite considerable progress has been made in fabricating precisely ordered architectures, achieving controlled motion in top-down fabricated structures remain a formidable challenge. Here, we introduce an advanced dynamic micron-nano optical platform featuring hierarchical microscale wrinkles integrated with ordered nanoscale arrays.

ConspectusHydrogen spillover, the simultaneous diffusion of protons and electrons, has recently emerged as a key phenomenon in the functionalization of hydrogen in cutting-edge research fields. Its occurrence has been found to significantly impact hydrogen-related fields of science, such as catalysis, reduction, and hydrogen storage. Since the discovery of hydrogen spillover more than half a century ago, although many scientists have reported its unique properties and have attempted to utilize them, no practical advanced applications have been established yet.

The development of high-performance, cost-effective non-noble metal catalysts for the oxygen evolution reaction (OER) is critical to advancing sustainable hydrogen production via water electrolysis. Herein, we report a facile and mild strategy for synthesizing amorphous bimetallic organic framework materials (NiFe-MOFs) using pyridine-modified threonine (l-PyThr) as an organic ligand. The optimized NiFe-PyThr-4:1 catalyst exhibits remarkable OER activity, requiring low overpotentials of only 162 and 222 mV to achieve current densities of 10 and 100 mA cm, respectively, along with a small Tafel slope of 34.

We report the performance of solid-state ceramic supercapacitors (SSCs) based on a novel composite electrolyte comprising aluminum-doped lithium lanthanum titanate perovskite, LiLaTiAlO (Al-doped LLTO), and the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF). Rietveld refinement of X-ray diffraction data confirms the preservation of the tetragonal perovskite phase after Al substitution, indicating structural stability of the host lattice. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy further corroborate the successful incorporation of Al without forming secondary phases.

However, multilayer MoS is largely overlooked because of its optically inactive indirect bandgap caused by interlayer coupling. It is highly desirable to modulate and decrease the interlayer coupling so that each layer in multilayer MoS can exhibit a monolayer-like direct-gap behavior.
