Coal-fired power plant is a major contributor to greenhouse gas emissions.The post-combustion capture is a promising method for CO2emission reduction but the high thermal demand is unbearable.To address this issue,solar thermal energy and CO2capture are jointly integrated into the coal-fired power plant in this study.The solar thermal energy is employed to meet the heat requirement of the CO2capture process,thereby avoiding the electricity loss caused by self-driven CO2capture.Furthermore,the heat released from the carbonation reaction of MgO adsorbent is integrated into the steam Rankine cycle.By partially substituting the extracted steam for feedwater heating,the electricity output of the power plant is further increased.According to the results from the developed model,the system could achieve a CO2capture rate of 86.5% and an electricity output enhancement of 9.8% compared to the reference system,which consists of a self-driven CO2capture coal-fired power plant and PV generation unit.The operational strategy is also optimized and the amount of CO2emission reduction on a typical day is increased by 11.06%.This work shows a way to combine fossil fuels and renewable energy for low carbon emissions and efficient power generation.

Thallium(Tl)compounds,highly toxic to biology,are usually released into flue gas during fossil/minerals combustion,and further distributed in water and soil.In this work,we fundamentally investigated the capture of gaseous Tl_(2)O by industrial V2O5-WO3/TiO_(2)catalyst under working condition in Tl-containing flue gas.Experimental and theoretical results indicated that the Tl_(2)O has significant electron-feeding capacity and easily donate electron to unoccupied orbitals of TiO_(2),leading to dismutation of Ti 2p and inartificial formation of p-n junction on TiO_(2)surface,which prompted Tl_(2)O selectively interacted with TiO_(2)in flue gas.Herein,we proposed and verified an effective way to capture gaseous Tl_(2)O,which offered almost the best choice to eliminate Tl emission from flue gas and expanded the function of the TiO_(2)-based catalyst.The formation of p-n junction on commercial V2O5-WO3/TiO_(2)catalyst under working condition was revealed for the first time,which can be a valuable reference for both heterocatalysis and electro/photocatalysis.

High applied thermal-stability and superior structural property for activated carbon adsorbent are extremely promising,which also is the determining short slab in volatile organic compounds(VOCs)adsorption applications.Herein,we develop the outstanding engineering carbon adsorbents from waste shaddock peel which affords greatly-enhanced thermal-stability and super structural property(S_(Lang)=4962.6 m2·g^(-1),Vmicro=1.67 cm^(3)·g^(-1)).Such character endows the obtained adsorbent with ultrahigh adsorption capture performance of VOCs specific to benzene(16.58 mmol·g^(-1))and toluene(15.50 mmol·g^(-1),far beyond traditional zeolite and activated carbon even MOFs materials.The structural expression characters were accurately correlated with excellent adsorption efficiency of VOCs by studying synthetic factor-controlling comparative samples.Ulteriorly,adsorption selectivity prediction at different relative humidity was demonstrated through DIH(difference of the isosteric heats),exceedingly highlighting great superiority(nearly sixfold)in selective adsorption of toluene compared to volatile benzene.Our findings provide the possibility for practical industrial application and fabrication of waste biomass-derived outstanding biochar adsorbent in the environmental treatment of threatening VOCs pollutants.

Amyloid beta-peptide 1-42(Aβ1-42)is one of the biomarkers of Alzheimer's disease,and its selective capture and quantitative detection are important for diagnosis and treatment of Alzheimer's disease.Herein,copper(Ⅱ)ions-immobilized virus-like hollow covalent organic frameworks(V-HCOFs@Cu^(2+))were synthesized by a facile approach.The as-prepared V-HCOFs@Cu^(2+)showed unique morphology,ultra-high specific surface(2552 m^(2)/g),uniform mesoporous structure(3.2 nm),superior chemical stability and abundant binding sites.Based on these excellent properties,the V-HCOFs@Cu^(2+)could be adopted as an ideal enrichment probe for highly efficient capture of Aβ1-42,exhibiting high adsorption capacity(320 mg/g),and fast adsorption equilibration time(3 min).In addition,an attractive approach of the V-HCOFs@Cu^(2+)-based matrix-assisted laser desorption/ionization mass spectrometry(MALDI-MS)was developed for the rapid screening and quantitative analysis of Aβ1-42 in human serum by using C-peptide as an internal standard,which exhibited low limit of detection(LOD,0.2 fmol/μL),and satisfactory recovery.This work provides an alternative solution for enrichment of biomarkers and also offers the potential applications of COFs in clinical analysis.

Exosomes are nanoscale membrane-enclosed extracellular vesicles secreted by various cells,which have enormous potential as disease biomarkers for clinical application.However,the isolation and detection of exosomes remain enormous challenges,which limits their further application.Herein,inspired by immunomagnetic beads,a magnetic nanoparticle conjugated aptamer was repurposed for the effective capture and detection of exosomes.The magnetic nanoparticles,composed of Fe 3 O 4 synthesized by the hydrothermal method as the core and coupled with gold nanoparticles(Fe 3 O 4@Au),provide a large specific surface area,making the resulting composite material an effective platform for exosome capture.Furthermore,the elution of captured exosomes with 1.0 M NaCl made downstream analysis of exosomes possible.The preliminary clinical application value of the composite in exosome analyses of serum from healthy individuals and patients with Alzheimer’s disease(AD)has also been verified,which could provide a promising platform for biomedical and clinical diagnosis.

Ash samples from corn stalk and coal co-fired at 0%,5%,10%,15%,20%,and 100%biomass were collected by a 4-stage wire-pipe type electrostatic precipitator (ESP),and the ratio of 14C/12C in ash samples from the 0%,20%,and 100% co-firing scenarios were measured by an accelerator mass spectrometer.The differential capture efficiency in electrostatic fields for coal ash,coal/biomass co-combustion ash (co- ash),and pure biomass ash was studied separately based on the ratio 14C/12C.Other factors that may influence capture efficiency were analyzed,including microscopic morphology,resistivity,dust density, and particle size distribution.The results indicate that co-ash may be efficiently captured by ESP,while pure biomass ash could not.Co-ash capture was mainly concentrated in the first two electrostatic fields in the lab-scale ESP,and the overall capture efficiency exceeded 90%.Biomass addition decreased the resistivity of co-ash,and enhanced its surface adsorption capacity to form agglomerates,facilitating the capture of co-ash.The capture efficiency of coal ash in co-ash was higher than that of pure coal ash in the first electrostatic field of the ESP.Co-firing biomass can aid the removal of both coal ash and biomass ash when using an ESP.

Among the wave energy converters (WECs), oscillating buoy is a promising type for wave energy development in offshore area. Conventional single-freedom oscillating buoy WECs with linear power take-off (PTO) system are less efficient under off-resonance conditions and have a narrow power capture bandwidth. Thus, a multi-freedom WEC with a nonlinear PTO system is proposed. This study examines a multi-freedom WEC with 3 degrees of freedom: surge, heave and pitch. Three different PTO systems (velocity-square, snap through, and constant PTO systems) and a traditional linear PTO system are applied to the WEC. A time-domain model is established using linear potential theory and Cummins equation. The kinematic equation is numerically calculated with the fourth-order Runge–Kutta method. The optimal average output power of the PTO systems in all degrees of freedom are obtained and compared. Other parameters of snap through PTO are also discussed in detail. Results show that according to the power capture performance, the order of the PTO systems from the best to worst is snap through PTO, constant PTO, linear PTO and velocity-square PTO. The resonant frequency of the WEC can be adjusted to the incident wave frequency by choosing specific parameters of the snap through PTO. Adding more DOFs can make the WEC get a better power performance in more wave frequencies. Both the above two methods can raise the WEC’s power capture performance significantly.

Hierarchically porous carbon materials are promising for energy storage,separation and catalysis.It is desirable but fairly challenging to simultaneously create ultrahigh surface areas,large pore volumes and high N contents in these materials.Herein,we demonstrate a facile acid-base enabled in situ molecular foaming and activation strategy for the synthesis of hierarchically macro-/meso-/microporous N-doped carbon foams(HPNCFs).The key design for the synthesis is the selection of histidine(His)and potassium bicarbonate(PBC)to allow the formation of 3D foam structures by in situ foaming,the PBC/His acid-base reaction to enable a molecular mixing and subsequent a uniform chemical activation,and the stable imidazole moiety in His to sustain high N contents after carbonization.The formation mechanism of the HPNCFs is studied in detail.The prepared HPNCFs possess 3D macroporous frameworks with thin well-graphitized carbon walls,ultrahigh surface areas(up to 3200 m^2 g^-1),large pore volumes(up to 2.0 cm^3 g^-1),high micropore volumes(up to 0.67 cm^3 g^-1),narrowly distributed micropores and mesopores and high N contents(up to 14.6 wt%)with pyrrolic N as the predominant N site.The HPNCFs are promising for supercapacitors with high specific capacitances(185-240 F g^-1),good rate capability and excellent stability.They are also excellent for CO2 capture with a high adsorption capacity(~4.13 mmol g^-1),a large isosteric heat of adsorption(26.5 kJ mol^-1)and an excellent CO2/N2 selectivity(~24).

Carbon dioxide(CO2) is the largest anthropogenic greenhouse gas(GHG) on the planet contributing to the global warming. Currently, there are three capture technologies of trapping CO2 from the flue gas and they are pre-combustion, post-combustion and oxy-fuel combustion. Among these, the post-combustion is widely popular as it can be retrofitted for a short to medium term without encountering any significant technology risks or changes.Activated carbon is widely used as a universal separation medium with series of advantages compared to the first generation capture processes based on amine-based scrubbing which are inherently energy intensive. The goal of this review is to elucidate the three CO2 capture technologies with a focus on the use of activated carbon(AC) as an adsorbent for post-combustion anthropogenic CO2 flue gas capture prior to emission to atmosphere. Furthermore, this coherent review summarizes the recent ongoing research on the preparation of activated carbon from various sources to provide a profound understanding on the current progress to highlight the challenges of the CO2 mitigation efforts along with the mathematical modeling of CO2 capture. AC is widely seen as a universal adsorbent due to its unique properties such as high surface area and porous texture. Other applications of AC in the removal of contaminants from flue gas, heavy metal and organic compounds, as a catalyst and catalyst support and in the electronics and electroplating industry are also discussed in this study.
