Recent progress on covalent organic framework materials as CO2 reduction electrocatalysts

open access: yesFrontiers in Chemistry, 2022
CO2 emission caused by fuel combustion and human activity has caused severe climate change and other subsequent pollutions around the world. Carbon neutralization via various novel technologies to alleviate the CO2 level in the atmosphere has thus become

Antibiotic exposure decreases soil arsenic oral bioavailability in mice by disrupting ileal microbiota and metabolic profile

open access: yesEnvironment International, 2021
Oral bioavailability of arsenic (As) determines levels of As exposure via ingestion of As-contaminated soil, however, the role of gut microbiota in As bioavailability has not evaluated in vivo although some in vitro studies have investigated this.

The atomic path for constructing single‐helical superstructure of AuCu bimetallic nanoclusters

open access: yesAggregate, 2023
Single‐helical or double‐helical structures are common in living organisms. Helical assembly has been found in the artificial nanoparticles, but how they do so remains poorly understood. Here, we exploit atomically precise Au6Cu6 bimetallic nanoparticles

Measurement of vehicle particulate emissions. [PDF]

open access: yesEnvironmental Health Perspectives, 1975
A constant volume sampler (CVS) compatible auto exhaust particulate sampling system has been built which samples exhaust isokinetically at constant temperature. This system yields internally consistent results and is capable of frequent and convenient operation.

Forecasting Greenhouse Gas Emissions from Heavy Vehicles: A Case study of Semarang City

open access: yesJurnal Presipitasi, 2021
In Indonesia, transportation sector, specifically road transport consumed most energy compared to other sectors. Eventually, the energy consumption will increase due to the growth of vehicle number that also escalate emission.
