TL;DR: In this paper, a facile one-step KOH activation procedure was explored to make the carbonaceous sorbents, which have advanced porous structure and hold superior CO2 uptake, up to 3.68 and 5.11 mmol/g.
Abstract: In
this work, porous carbons were achieved from sustainable biomass
lotus stalk. Unlike the common carbonization-activation two-step method,
a facile one-step KOH activation procedure was explored to make the
carbonaceous sorbents. The as-made adsorbents have advanced porous
structures and hold superior CO2 uptake, up to 3.68 and
5.11 mmol/g at 1 bar, 25 and 0 °C, respectively. After carefully
checking the relationship of CO2 uptake with each porous
characteristic, the volume of narrow micropores is found to be the
leading factor that determines the CO2 adsorption abilities
of the adsorbents under ambient conditions. Moreover, the narrower
pore size distribution is also preferential to the adsorption of CO2. Apart from the high CO2 uptake, these lotus stalk-derived
adsorbents also possess extra excellent CO2 capture properties
such as good recyclability, fast adsorption kinetics, reasonable CO2/N2 selectivity, suitable heat of adsorption, and
high dynamic adsorption capacity. These results demonstrate that these
cost-effective carbonaceous adsorbents developed by the facile one-step
method have potential in the application of actual CO2 capture.

TL;DR: In this paper, the authors present a critical overview of three widely used nanoprecipitation techniques, namely, traditional nanoprecipient in bulk solutions, flash nanop-recipient, and micro-fluidic-based nanop-reconstruction, summarizing their key characteristics, advantages and disadvantages.
Abstract: Significant efforts have been made to fabricate drug-loaded nanoparticles for drug delivery. Nanoprecipitation is a simple and versatile method for making various types of polymer nanoparticles with well-controlled particle size, size distribution, and surface properties. This review presents a critical overview of three different widely used nanoprecipitation techniques, namely, traditional nanoprecipitation in bulk solutions, flash nanoprecipitation, and microfluidic-based nanoprecipitation. The review starts with the comparison of these three different nanoprecipitation methods summarizing their key characteristics, advantages, and disadvantages. Then, different types of nanoparticles synthesized using nanoprecipitation are presented including di-block copolymer nanoparticles and natural polymer nanoparticles. A special focus is placed on comparing different drug-loaded polymer nanoparticles prepared using different nanoprecipitation approaches including their synthesis methods, drug loading, encapsulation efficiency, nanoparticle properties (e.g., size, PDI, etc.), and stability. Finally, the principle of forming nanoparticles with well-controlled properties is discussed to fundamentally understand the intricate interplay between mixing, supersaturation, nucleation, and particle growth, aiming to provide a general guideline for making drug-loaded nanoparticles based on nanoprecipitation.

TL;DR: In this article, two new quantitative structure-property relationship (QSPR) models based on conductor-like screening model for real solvent (COSMO-RS) molecular charge density distributions (Sσ-profiles) were developed using the data obtained from the literature.
Abstract: This work presents the development
of molecular-based mathematical
models for the prediction of electrical conductivity of deep eutectic
solvents (DESs) Two new quantitative structure–property relationship
(QSPR) models based on conductor-like screening model for real solvent
(COSMO-RS) molecular charge density distributions (Sσ-profiles) were developed using the data obtained
from the literature The data comprise 236 experimental electrical
conductivity measurements for 21 ammonium- and phosphonium-based DESs,
covering a wide range of temperatures and molar ratios First, the
hydrogen-bond acceptors (HBAs) and hydrogen-bond donors (HBDs) of
each DES were successfully modeled using COSMO-RS Then, the calculated Sσ-profiles were used as molecular descriptors
The relation between the conductivity and the descriptors in both
models has been expressed via multiple linear regression
The first model accounted for the structure of the HBA, the HBD, the
molar ratio, and temperature, whereas the second model additionally
incorporated the interactions between the molecular descriptors The
results showed that by accounting for the interactions, the regression
coefficient (R2) of the predictive model
can be increased from 0801 to 0985 Additionally, the scope and
reliability of the models were further assessed using the applicability
domain analysis The findings showed that QSPR models based on Sσ-profiles as molecular descriptors are
excellent at describing the properties of DESs Accordingly, the obtained
model in this work can be used as a useful guideline in selecting
DESs with the desired electrical conductivity for industrial applications

TL;DR: In this paper, a manganese well-dispersed on Fe3O4 microsphere (Mn-Fe 3O4) catalyst was synthesized for the direct conversion of carbon dioxide (CO2) into light olefins.
Abstract: In this work, manganese well-dispersed on Fe3O4 microsphere (Mn–Fe3O4) catalyst was synthesized. It exhibited excellent catalytic performance for the direct conversion of carbon dioxide (CO2) into light olefins. A CO2 conversion of 44.7% with high selectivity of light olefin (46.2%, yield of 18.7%), high O/P ratio (6.5), and low selectivity of CO (9.4%) was obtained over the 10Mn–Fe3O4 catalyst. The Mn–Fe3O4 catalyst was studied by XRD, SEM, (HR)TEM, STEM–EDS, H2-TPR, and CO2-TPD. The result indicated that the manganese promoter could facilitate the adsorption of CO2 and the activation of C═O bonds as well as inhibit the secondary hydrogenation. This work offered a novel Fe-based catalyst system to the utilization of CO2 and an understanding in promoting C═O bond activation in the first step of CO2 hydrogenation to hydrocarbon reaction.

TL;DR: In this paper, a photoelectrochemical (PEC) reduction of CO₂ is proposed to solve the problem of unsatisfactory conversion efficiency and poor product selectivity in aqueous solution.
Abstract: Photoelectrochemical (PEC) reduction of CO₂ is a potential way to simultaneously address environmental problems and reduce the energy crisis. However, traditional conversion of CO₂ in aqueous solution has serious drawbacks, such as low solubility, slow diffusion, and complicated existing form of CO₂ in water, as well as the competitive H₂ evolution from reduction of H₂O, leading to unsatisfactory conversion efficiency and poor product selectivity. To overcome these problems, in this work, gas CO₂ has been directly introduced to a flow cell, in which a membrane cathode assembly with Ag nanocube electrocatalysts is used. It is surprising to find that with this PEC reduction strategy, the product selectivity of CO can be substantially enhanced with the suppression of competitive H₂ evolution. The control experiments and theoretical calculations suggest that the facile mass transfer of gas CO₂ to the (100) plane of Ag nanocubes electrocatalysts and the suitable photocurrent density may account for such advantages.
