AbstractActivated carbons are one of the most important classes of high‐surface‐area porous materials. Owing to their unique structure, low price, and large‐scale production technology, these porous carbons have been traditionally used as sorbents for eliminating contamination. In the past decade, many innovations have been seen in the synthesis, structure, applications, and theoretical and experimental methods. Herein, a comprehensive review of the up‐to‐date progress of activated carbons is presented from the viewpoint of synthetic chemistry and materials science. First, the critical textural properties are discussed, with special emphasis on the porous texture, heteroatom doping, surface functional groups, and partial graphitization. Next, the advanced synthetic strategies of activated carbons are summarized. Special attention is given to the reaction mechanism between activating agents and carbon sources, as well as the design of controlled forms and morphology. Then, their applicability in various emerging fields is covered, including supercapacitors, capacitive deionization, batteries, electrocatalysis, and carbon capture. In particular, this review highlights the potential synthesis–structure–property correlations of these porous materials. Finally, we present the future challenges and outlook for their success in energy and environmental science.

AbstractThe advent of Z‐scheme heterojunction makes it possible to improve the CO2 photoreduction efficiency of photocatalyst significantly. However, the reasonable construction of heterojunction and study of the photocatalytic mechanism remains a major challenge. Here, the Z‐scheme heterojunction photocatalyst (BP:La/InVO4:La) based on La single atom anchored on black phosphorus for photocatalytic CO2 reduction with ≈100% CO selectivity is successfully constructed. The CO generation rate of BP:La/5‐InVO4:La is ≈7.9 and 4.9 times higher than black phosphorus and InVO4, respectively. The results of X‐ray photoelectron spectroscopy, photoluminescence, and density functional theory indicate that the BP:La/InVO4:La belongs to the Z‐scheme heterojunction, and the La single atom plays multiple roles such as regulating surface active sites, promoting CO2 absorption, and increasing O defects, which can further contribute to the improvement of photocatalytic performance. The enhanced selectivity of the Z‐scheme heterojunction is further demonstrated by calculating the rate‐determining steps and selectivity‐determining steps. The results are expected to provide unique ideas for the rational design of rare earth composite photocatalyst.

AbstractAssembling molecular catalytic centers into crosslinked networks is widely used to fabricate heterogeneous catalysts but they often suffer loss in activity and selectivity accompanied by unclear causes. Here, a strategy for the construction of heterogeneous catalysts to induce activity and selectivity by bottom‐up introduction of segregated electron‐conduction and mass‐transport interfaces into the catalytic materials is reported. The catalytic skeletons are designed to possess different π orderings for electron motion and the open channels are tailored to install finely engineered walls for mass transport, so that origins of activity and selectivity are correlated. The resultant covalent organic framework catalysts with ordered π skeletons and solvophobic pores increase activity by two orders of magnitude, enhance selectivity and energy efficiency by 70‐fold, and broaden the voltage range, to promote CO2 transformation under ambient conditions. The results open a way to precise interfacial design of actionable heterogeneous catalysts for producing feedstocks from CO2.

AbstractUltrashort laser pulses deliver electromagnetic energy to matter causing its localized heating that can be used for both material removal via ablation/evaporation and driving interface chemical reactions. Here, it is shown that both mentioned processes can be simultaneously combined within straightforward laser nanotexturing of Si wafer in a functionalizing solution to produce a practically relevant metal–semiconductor surface nano‐morphology. Such unique hybrid morphology represents deep‐subwavelength Si laser‐induced periodic surface structures (LIPSSs) with an extremely short period down to 70 nm and high‐aspect‐ratio nano‐trenches loaded with controllable amount of plasmonic nanoparticles formed via laser‐induced decomposition of the precursor noble‐metal salts. Moreover, heat localization driving reduction process is utilized to produce surface morphology locally decorated with dissimilar plasmon‐active nanoparticles. Light‐absorbing deep‐subwavelength Si LIPSSs loaded with controllable amount of noble‐metal nanoparticles represent an attractive architecture for plasmon‐related applications such as optical nanosensing where efficient coupling of the propagating optical waves to highly localized electromagnetic “hot spots” is a mandatory requirement. To support this statement, applicability of such hybrid morphology for fluorescence‐based detection of nanomolar concentrations of mercury cations in solution is demonstrated.

Published: August 2022

AbstractMultifunctional organic optoelectronic devices are of great significance for the development of low‐energy consumption and space‐constrained systems. Herein, multifunctional organic photodiodes integrating transient light detection and photo‐synaptic functions in one device are unprecedentedly achieved upon readily changing the direction of the external bias. Under negative bias, the devices exhibit excellent photodetection performance with high shot‐noise‐limited specific detectivity ( > 1013 Jones) in the range from ultraviolet, visible, to near infrared and large linear dynamic range (188 dB at 915 nm), which are among the best organic photodetectors. Interestingly, the photodiode devices change to work as organic photosynapses upon tuning the external bias to be positive. Associative learning behavior is successfully simulated in an all‐optical way, while high image recognition accuracy (>80%) is realized based on artificial neural network. The mechanism studies reveal that the interface energy barrier is critical for achieving the multi‐function in one device. Finally, the universality of electrically switchable transient light detection and photo‐synaptic functions is further studied. This work provides a novel method for constructing vertical diode‐type organic optical synapses and developing multifunctional organic electronics.

AbstractLithium metal anodes are regarded as the most promising candidate for rechargeable lithium‐based batteries, but uncontrollable Li dendrites hinder further applications. Here, sine‐wave analogous MXene (Ti3C2Tx) (SWA‐MXene) layers are produced by spreading aqueous MXene dispersion onto the sectional surface of a metallic coil and subsequently drying at room temperature. COMSOL Multiphysics simulations demonstrate that the low curvature in SWA‐MXene layers homogenizes the distributions of lithium ions and electric field, efficiently eliminating the lightning‐rod effect on the surface of aligned electrodes in the process of Li deposition. As a result, the flexible SWA‐MXene layers show a low overpotential for lithium nucleation (≈13.5 mV at 0.05 mA cm−2) and deep plating–stripping capacities up to 40 mAh cm−2, as well as a long cycle life up to 1250 h. Full cells consisting of a SWA‐MXene–Li anode and a LiFePO4 cathode also exhibit a durable cycle life up to 420 cycles at 1088 mA g−1.

AbstractSpiro‐OMeTAD is one of the most used hole transport layers (HTLs) in high efficiency n‐i‐p perovskite solar cells (PSCs). However, due to the unsatisfactory conductivity of pristine Spiro‐OMeTAD, additives such as tert‐butylpyridine (tBP) and lithium bis (trifluoromethylsulfonyl)‐imide (LiTFSI) are required to improve its hole transportation. The hygroscopic nature of these additives inevitably deteriorates the device's stability. Here, it is shown that by adding fluorinated graphene (FG) into the Li‐TFSI and tBP doped Spiro‐OMeTAD, both efficiency and stability of the PSCs are significantly enhanced. Using the FG incorporated Spiro‐OMeTAD HTL, the power conversion efficiency (PCE) of the PSC reaches 21.92%, which is 11.8% higher than the original device. The FG not only improves the hole mobility of Spiro‐OMeTAD but also effectively reduces the amount of lithium ions in the perovskite layer and improves the hydrophobicity of the HTL. The FG incorporating cell shows better stability, maintaining 90% of initial efficiency over a 2400 h test in ambient conditions with 25% humidity. Finally, it is further demonstrated that the valence band of FG incorporated Spiro‐OMeTAD HTL has a positive effect on PSCs with a 2D interfacial layer, achieving an impressive PCE of 23.14% and a Voc of 1.226 V.

AbstractPerovskite based photovoltaic (PV) cells are unique in combining low open‐circuit voltage losses with a broad bandgap tunability. This makes them an ideal PV cell to recycle photons back into electrical power in a variety of illumination systems or light emitting devices. Here, advantage of these features is taken and wide bandgap (WBG) perovskite PV cells are incorporated in devices suitable for display illumination and demonstrate a high yield in stray light recycling back into electricity with up to a 37.5% power conversion efficiency. The specific device considered is a modified half‐cylinder photonic plate designed to emit diffused broadband polarized light using a nonabsorbing reflective polarizer based on a random dielectric layer distribution. It is experimentally demonstrated that light recycling using appropriately tuned WBG perovskite PV cells becomes very efficient when implemented in systems where the light is emitted from narrowband sources, even if the emission spans a broad wavelength range.

AbstractThis paper reports the synthesis of enantiopure aryl alkyl ethers via the Pd(II)‐catalyzed picolinamide‐aided γ‐C(sp2)−H alkoxylation of various enantiopure α‐alkylbenzylamine derivatives using alcohols. Enantiopure α‐methylbenzylamines and amino alcohol substrates such as 2‐amino‐2‐phenylethanol (phenylglycinol) and 3‐amino‐3‐phenylpropanol were subjected to the γ‐C(sp2)−H alkoxylation (etherification) with alcohols using PIDA. α‐Alkylbenzylamines and phenylglycinols are valuable building blocks in organic synthesis and medicinal chemistry research areas. Accordingly, this work has enabled the assembling of various enantiopure ortho‐alkoxylated α‐methylbenzylamine and 2‐amino‐2‐phenylethanol (phenylglycinol) and 3‐amino‐3‐phenylpropanol derivatives containing aryl alkyl ether functionality. We have shown the utility of ortho‐alkoxylated α‐methylbenzylamine derivatives for assembling enantiopure α‐methylbenzylamine‐based sulfamoylcarbamates and carboxamides which are structurally related to the bio‐active compounds known in the literature. This work demonstrates the substrate scope elaboration in C−H functionalization and etherification through the C−O bond‐forming process and synthesis of aryl alkyl ether functionality containing enantiopure α‐alkylbenzylamines.

AbstractBackgroundProductivity loss and activity limitations due to chronic rhinosinusitis (CRS) are known to contribute to the significant economic and personal burden of disease. The purpose of this study was to assess productivity and activity impairment before and after endoscopic sinus surgery (ESS) for medically refractory CRS.MethodsThis investigation was a prospective, multi‐institutional, observational cohort study. Patients diagnosed with medically refractory CRS completed the Work Productivity and Activity Impairment—Specific Health Problem (WPAI‐SHP) questionnaire before surgery and approximately 6 months after the procedure. Factors associated with minimal clinical important differences (MCIDs) for productivity and activity impairment were identified.ResultsA total of 279 study participants were screened for inclusion, of whom 176 (63.1%) with postoperative follow‐up were included in the final cohort. Preoperative productivity and activity impairment were observed in 63.2% and 69.8% of the patients, respectively. Among these patients, postoperative improvement equaling at least 1 MCID was reported in both productivity (76.1%) and activity (76.4%) impairments. Multivariate regression identified sphenoidotomy (odds ratio [OR], 4.18; 95% confidence interval [CI], 1.03‐17.02) as the only factor associated with increased likelihood of productivity improvement, whereas septoplasty during ESS (OR, 8.45; 95% CI, 2.33‐30.68) and migraine (OR, 0.35; 95% CI, 0.12‐0.96) were associated with differential odds of activity improvement.ConclusionCRS is associated with a substantial burden on productivity and activity that significantly improves after treatment with ESS. These data may facilitate improved patient counseling and shared decision‐making regarding surgical management for CRS.

AbstractIntroductionScreening potential participants in Alzheimer's disease (AD) clinical trials with amyloid positron emission tomography (PET) is often time consuming and expensive.MethodsA web‐based application was developed to model the time and financial cost of screening for AD clinical trials. Four screening approaches were compared; three approaches included an AD blood test at different stages of the screening process.ResultsThe traditional screening approach using only amyloid PET was the most time consuming and expensive. Incorporating an AD blood test at any point in the screening process decreased both the time and financial cost of trial enrollment. Improvements in AD blood test accuracy over currently available tests only marginally increased savings. Use of a high specificity cut‐off may improve the feasibility of screening with only an AD blood test.DiscussionIncorporating AD blood tests into screening for AD clinical trials may reduce the time and financial cost of enrollment.HIGHLIGHTS

ObjectiveHigh cerebral arterial pulsatility index (PI), white matter lesions (WMLs), enlarged perivascular spaces (PVSs), and lacunar infarcts are common findings in the elderly population, and considered indicators of small vessel disease (SVD). Here, we investigate the potential temporal ordering among these variables, with emphasis on determining whether high PI is an early or delayed manifestation of SVD.MethodsIn a population‐based cohort, 4D flow MRI data for cerebral arterial pulsatility was collected for 159 participants at baseline (age 64–68), and for 122 participants at follow‐up 5 years later. Structural MRI was used for WML and PVS segmentation, and lacune identification. Linear mixed‐effects (LME) models were used to model longitudinal changes testing for pairwise associations, and latent change score (LCS) models to model multiple relationships among variables simultaneously.ResultsLongitudinal 5‐year increases were found for WML, PVS, and PI. Cerebral arterial PI at baseline did not predict changes in WML or PVS volume. However, WML and PVS volume at baseline predicted 5‐year increases in PI. This was shown for PI increases in relation to baseline WML and PVS volumes using LME models (R 0.24; p < 0.02 and R 0.23; p < 0.03, respectively) and LCS models ( = 0.28; p = 0.015 and = 0.28; p = 0.009, respectively). Lacunes at baseline were unrelated to PI.InterpretationIn healthy older adults, indicators of SVD are related in a lead–lag fashion, in which the expression of WML and PVS precedes increases in cerebral arterial PI. Hence, we propose that elevated PI is a relatively late manifestation, rather than a risk factor, for cerebral SVD. ANN NEUROL 2022;92:871–881
From waste to wealth: A critical review on advanced materials for EMI shielding

Published: August 2022

AbstractSolid waste generation has increased enormously due to development in a fast‐moving world. Large amounts of industrial and agricultural waste are either incinerated or subject to landfilling, accounting for increasing air and water pollution. The 3 “R”s of waste management, reduce, reuse, and recycle, in most cases, deduce themselves to a theoretical topic. However, a stage has reached where the primary importance should be given to waste management and sustainable development where reprocessing the materials into new functional materials helps to reduce the consumption of fresh raw materials and reduces various forms of pollution. In this context, this review focuses on eliminating adverse environmental impacts of solid wastes by using various industrial by‐products and bio‐wastes as raw materials for EMI (Electromagnetic interference) shielding applications. In this review, we covered the sources, effects of electromagnetic radiation, mechanism, and factors affecting EMI shielding, synthesis of shielding materials derived from animal waste, agricultural waste, paper waste, fly ash, rubber waste. Thus, this review opens up novel opportunities by upcycling waste materials from multiple sources into highly efficient shielding materials.
