Active transportation such as walking, bicycling, scootering, or using a wheelchair has direct physical and mental health benefits. Electric bicycles (e-bikes) have great potential as a form of active transportation. The Massachusetts Clean Energy Center partnered with the Massachusetts Bicycle Coalition (MassBike) to develop and pilot test a program to provide free pedal assist e-bikes with implementation support for income-eligible residents in Worcester, MA as a strategy to reduce greenhouse gas emissions that contribute to climate change. MassBike received program funding over two years to provide 100 free e-bicycles to income-eligible individuals who live or work in Worcester utilizing a community-engaged approach. The e-bike pilot program took place from August 2022-May 2024. Overall, 64% of the 96 participants regularly reported their e-bike usage during the first 13 months of deployment. Per month, participants who reported their usage on average made 17 trips, rode 65 miles, and were physically active for 20 minutes per trip using their e-bike. Program results demonstrated high aggregate levels as well as strong start-up levels with a return to similar results when weather became milder after winter dips. Lessons learned include the time needed for behavior shifts and retention and reporting challenges. These preliminary results offer a glimpse of the opportunities for increased physical activity possible with a climate change mitigation strategy of active transportation.

The design of highly efficient photocatalysts to photoreduce nitrogen (N) to ammonia (NH) under mild conditions is extremely challenging. In this work, various molar ratio of molybdenum (Mo) is incorporated into BiOCl via a hydrothermal process. The resulting Mo-doped BiOCl exhibits remarkable solar-driven activity for N photo fixation without any scavengers or sacrificial agents.

Bioelectrodes function as a critical interface for signal transduction between living organisms and electronics. Conducting polymers (CPs), particularly poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), are among the most promising materials for bioelectrodes, due to their electrical performance, high compactness, and ease of processing, but often suffer from degradation or de-doping even in some common environments (e.g.

The delicate construction of electrocatalysts with high catalytic activity is a strategic method to enhance the kinetics of lithium-sulfur batteries (LSBs). Adjusting the local structure of the catalyst is always crucial for understanding the structure-activity relationship between atomic structure and catalyst performance. Here, in situ induction of electron-deficient B enables phase engineering MoC, realizing the transition from hexagonal (h-MoC) to cubic phase (c-B-MoC).

Enhancing the performance of organic solar cells (OSCs) is essential for achieving sustainability in energy production. This study presents an innovative strategy that involves fine-tuning the thickness of the bulk heterojunction (BHJ) photoactive layer at the nanoscale to improve efficiency. The organic blend D18:L8-BO is utilized to capture a wide range of photons while addressing the challenge of minimizing optical losses from low-energy photons.

Macrophage mitochondrial dysfunction, caused by oxidative stress, has been proposed as an essential event in the progression of chronic inflammation diseases, such as atherosclerosis. The cluster of differentiation-36 (CD36) and lectin-like oxLDL receptor-1 (LOX-1) scavenger receptors mediate macrophage uptake of oxidized low-density lipoprotein (oxLDL), which contributes to mitochondrial dysfunction by sustained production of mitochondrial reactive oxygen species (mtROS), as well as membrane depolarization. In the present study, the antioxidant mechanisms of action of the selective synthetic azapeptide CD36 ligand MPE-298 have been revealed.
