Algal Biochar-Metal Nanocomposite Particles Tailor the Hydration Kinetics and Compressive Strength of Portland Cement Paste.

Biochar can improve the mechanical properties of portland cement paste and concrete. In this work, we produced algal biochar-zinc (biochar-Zn) and algal biochar-calcium (biochar-Ca) nanocomposite particles and studied their effect on the hydration kinetics and compressive strength of cement paste. Results show that 3 wt % biochar-Zn delayed peak heat evolution during cement hydration from 8.

Perspectives on Cobalt Supply through 2030 in the Face of Changing Demand.

Lithium-ion battery demand, particularly for electric vehicles, is projected to increase by over 300% throughout the next decade. With these expected increases in demand, cobalt (Co)-dependent technologies face the risk of significant impact from supply concentration and mining limitations in the short term. Increased extraction and secondary recovery form the basis of modeling scenarios that examine implications on Co supply to 2030.

Everyday Discrimination Prospectively Predicts Inflammation Across 7-Years in Racially Diverse Midlife Women: Study of Women's Health Across the Nation.

Self-reported discrimination has emerged as a predictor of negative psychological and physical health outcomes across racial/ethnic groups. The goals of this study were to determine whether C-reactive protein (CRP), a marker of inflammation and risk factor for future cardiovascular disease (CVD) was independently predicted by everyday discrimination or whether race or body mass index (BMI) modified this association over a 7-year period among 2,490 women from racially diverse backgrounds. At baseline, the 10-item Williams' measure of everyday discrimination was administered.

Childhood socioeconomic status is associated with psychosocial resources in African Americans: the Pittsburgh Healthy Heart Project.

Objective: To determine whether lower childhood socioeconomic status (SES) was associated with fewer psychosocial resources independent of adult SES, and whether these associations differed by race/ethnicity.

Method: Cross-sectional study of 342 middle-aged (M = 60.5 ± 4.

Unfair treatment is associated with poor sleep in African American and Caucasian adults: Pittsburgh SleepSCORE project.

Objective: To test the association between self-reported unfair treatment and objective and self-reported sleep characteristics in African American and Caucasian adults.

Design: Cross-sectional study of 97 African American and 113 Caucasian middle-aged adults.

Main Outcome Measures: Participants completed: (a) two-night in-home, polysomnography (PSG) sleep study, (b) sleep diaries and actigraph assessments across 9 days and nights, and (c) self-report measures of sleep quality in the past month, and daytime sleepiness in the past 2 weeks.

Unfair treatment and trait anger in relation to nighttime ambulatory blood pressure in African American and white adolescents.

Objective: To determine if ambulatory blood pressure (ABP) at night relative to day ABP among adolescents is influenced by unfair treatment and trait anger, and whether these associations are stronger in African Americans and adolescents from lower socioeconomic status (SES) families and neighborhoods.

Methods: A total of 189 healthy white and African American adolescents (ages = 14-16 years, standard deviation = 0.62, 50% female) completed 2 days and 1 night of ABP monitoring and unfair treatment and trait anger questionnaires.

Coping with racism: a selective review of the literature and a theoretical and methodological critique.

Racism is a stressor that contributes to racial/ethnic disparities in mental and physical health and to variations in these outcomes within racial and ethnic minority groups. The aim of this paper is to identify and discuss key issues in the study of individual-level strategies for coping with interpersonal racism. We begin with a discussion of the ways in which racism acts as a stressor and requires the mobilization of coping resources.

Racism and ambulatory blood pressure in a community sample.

Objective: Racism has been identified as a psychosocial stressor that may contribute to disparities in the prevalence of cardiovascular disease. The goal of the present article was to investigate the relationship of perceived racism to ambulatory blood pressure (ABP) in a sample of American-born Blacks and Latinos.

Methods: Participants included English-speaking Black or Latino(a) adults between the ages of 24 and 65.
