Guidelines for evaluation and treatment of lead poisoning of wild raptors

open access: yesWildlife Society Bulletin, 2017
Lead poisoning is a threat to birds, particularly scavenging birds of prey. With the availability of portable lead‐testing kits, an increasing number of field researchers are testing wild‐caught birds, in situ, for lead poisoning.

MXene Membrane as Multifunctional Interface for Vapor Splitting via Photothermal‐Catalytic Membrane Distillation

open access: yesAdvanced Materials, EarlyView.
A multifunctional MXene‐based membrane integrates photothermal evaporation and photocatalytic vapor splitting in a sweeping‐gas membrane distillation (PTC‐SGMD) platform, simultaneously generating freshwater and hydrogen. The SrTiO3/MX@PVDF interface leverages broad‐spectrum solar absorption, efficient heat/mass transfer, and gas–solid catalysis to ...

Lead poisoning and its effects on bone density

open access: yesScientific Reports
Lead poisoning is a significant health concern, impacting multiple organs in the body, including the musculoskeletal system. While some studies suggest a link between lead exposure and reduced Bone Mineral Density (BMD), others report no significant ...

Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

open access: yesAdvanced Materials, EarlyView.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

High‐Performance Zero‐Gap Glycerol‐Fed Electrolyzer for C3 Chemicals and Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
This work presents a dynamic, self‐regulating operation strategy that enables selective glycerol electrooxidation in the OER‐free regime, co‐producing C3 chemicals and hydrogen at cell voltages below 1.25 V. Voltage‐ and temperature‐resolved analyses define optimal operating conditions, achieving a sustained current density of 500 mA cm−2 at ∼1.21 V ...

The Status of Childhood Lead Poisoning and Prevention in Nevada, USA

open access: yesThe Scientific World Journal, 2007
One of the first steps in addressing the problem of childhood lead poisoning is to identify the possible sources of exposure in specific communities and target high-risk populations with appropriate interventions. Due to several factors, such as lack of

Operando X‐ray Spectroscopy Study of Pd and Pd–Au Laterally Condensed Catalysts during Selective Acetylene Hydrogenation: The Role of Carbon

open access: yesAdvanced Materials, EarlyView.
The selective hydrogenation of acetylene over laterally condensed Pd and Pd–Au catalysts (LCCs) was investigated using operando X‐ray absorption and photoelectron spectroscopy in combination with density functional theory. Pd‐LCCs were found to incorporate significantly more carbon into the metal lattice than Pd–Au LCCs, where the carbon uptake governs

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

open access: yesAdvanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...

One in Four US Households Likely Exceed New Soil Lead Guidance Levels

open access: yesGeoHealth
Lead exposure has blighted communities across the United States (and the globe), with much of the burden resting on lower income communities, and communities of color.

Blood Lead Levels among Children in Yaoundé Cameroon

open access: yesFrontiers in Public Health, 2017
Blood lead levels (BLLs) are a useful indication of a population exposure to lead from environmental sources. No previous published study had reported BLLs in Cameroon.
