Significance Bioactive lipids control a wide variety of physiologic processes. We have recently identified branch bioactive lipid signaling mediated by N -acyl amino acids (NAAs) and the circulating enzyme peptidase M20 domain-containing 1 (PM20D1). Here we generate characterize mice globally deficient in PM20D1. These PM20D1-KO bidirectional changes NAA levels blood tissues exhibit metabolic nociceptive phenotypes. Our findings elucidate endogenous functions for vivo suggest PM20D1...
Prediction of chemical reaction outcomes using machine learning (ML) has emerged as a powerful tool for advancing materials synthesis. However, this approach requires large and diverse datasets, which are extremely limited in the field nanomaterials synthesis due to inconsistent nonstandardized reporting literature lack understanding synthetic mechanisms. In study, we extracted parameters InP quantum dot (QD) syntheses our inputs resultant properties (absorption, emission, diameter) outputs...
Measuring and modulating charge-transfer processes at quantum dot interfaces are crucial steps in developing dots as photocatalysts. In this work, cyclic voltammetry under illumination is demonstrated to measure the rate of photoinduced charge transfer from CdS by directly probing changing oxidation states a library molecular acceptors, including both hole electron acceptors. The data demonstrate presence long-lived donor generated native photodoping well positive correlation between driving...
Nanoscale tetrapods were synthesized with independently tunable core and arm sizes aspect ratios from a spectrum of quantum dot seeds, including ZnTe, CuInS2, InP, InP/ZnS, Cd3P2. The range II–VI, I–III–VI, III–V, II–V seeds included both cubic tetragonal lattices, demonstrating the versatility CdS growth upon surfaces accessible (111) planes, those distorted structures. Except for Cd3P2 where effect is inconsequential, cation exchange in was observed to occur concurrently give alloyed cores...
N-Acyl amino acids directly bind mitochondria and function as endogenous uncouplers of UCP1-independent respiration. We found that administration N-acyl to mice improves glucose homeostasis increases energy expenditure, indicating this pathway might be useful for treating obesity associated disorders. report the full account synthesis mitochondrial uncoupling bioactivity lipidated their unnatural analogues. Unsaturated fatty acid chains medium length neutral head groups are required optimal...
Intrinsic active site ensembles on Ni 2 P nanocrystal surfaces direct the selective reduction of nitrate to ammonia through potential-dependent co-adsorption H* and NO x *.
We present a method to measure relative energies between binding conformations of carboxylate ligands on InP magic-sized clusters in solution. Using Markov chain Monte Carlo global fitting analysis temperature-dependent vibrational spectra cluster-bound ligands, we observe significantly different various bidentate and monodentate motifs. Relative the motif, chelating conformation is 0.7 ± 0.3 kcal/mol more stable syn–syn bridging 1.1 0.5 stable, but syn–anti exhibits no significant...
Semiconductor quantum dots (QDs) are efficient organic photoredox catalysts due to their high extinction coefficients and easily tunable band edge potentials. Despite the majority of surface being covered by ligands, our understanding effect ligand shell on photocatalysis is limited steric effects. We hypothesize that we can increase activity QD photocatalysts designing a with targeted electronic properties, namely, redox-mediating ligands. Herein, functionalize QDs hole-mediating ferrocene...
CdS QDs are widely employed as photocatalysts for reactions such hydrogen evolution, and its degradation under aerobic, aqueous conditions is well understood. However, despite evidence of aggregation precipitation QD inert conditions, catalyst speciation under-explored. In this work, we demonstrate that during a reductive dehalogenation reaction, undergo surface ligand etching, leading to loss colloidal stability the formation micro-crystalline cadmium metal deposits. We hypothesize results...
Chemistry students at community colleges often experience a lack of hands-on research opportunities, which can be significant disadvantage when they transition to four-year universities. To address this, the Summer Research Opportunities for Community College Students (SCROCCS) was established in 2022 by graduate University Washington provide early chemical exposure college Greater Puget Sound area. SCROCCS has two primary goals: (1) participating with and skills crucial their success...
Active site ensembles on transition metal phosphides tune the selectivity of nitrate reduction reaction and mitigate competing hydrogen evolution. Using Ni2P nanocrystals as a case study, we demonstrate evidence competitive Langmuir-Hinshelwood mechanism that involves co-adsorption both H* NOx* intermediates impact intermediate binding energetics toward NH3.
Despite the ubiquity of electricity in many parts world, there are still over a billion people who do not have access to reliable electric grid. Distributed solar energy has emerged as low-cost solution for these off-grid communities gain electricity. These tend be rural, remote, or agricultural regions where it can expensive extend existing electrical infrastructure. Such also been shown slowest recover post-disaster situations, infrastructure damaged. Addressing this need, our group...
