Context.—
Studies of lungs in patients with COVID-19 have focused on early findings.

Objective.—
To systematically study histopathologic and imaging features and presence of SARS-CoV-2 RNA in lung tissue from patients in later stages of COVID-19.

Design.—
Autopsies, explants, surgical lung biopsies, transbronchial biopsies, cryobiopsies, and needle biopsies from patients with COVID-19 whose onset of symptoms/confirmed diagnosis was more than 28 days before the procedure were studied. Available images were reviewed. Reverse transcription droplet digital polymerase chain reaction for SARS-CoV-2 RNA was performed on lung tissue.

Results.—
Of 44 specimens (43 patients; median age, 59.3 years; 26 [60.5%] male) features of acute lung injury (ALI) were seen in 39 (88.6%), predominantly organizing pneumonia and diffuse alveolar damage, up to 298 days after onset of COVID-19. Fibrotic changes were found in 33 specimens (75%), most commonly fibrotic diffuse alveolar damage (n = 22) and cicatricial organizing pneumonia (n = 12). Time between acquiring COVID-19 and specimen was shorter in patients with diffuse ALI (median, 61.5 days) compared with patients with focal (140 days) or no ALI (130 days) (P = .009). Sixteen (of 20; 80%) SARS-CoV-2 reverse transcription droplet digital polymerase chain reaction tests were positive, up to 174 days after COVID-19 onset. Time between COVID-19 onset and most recent computed tomography in patients with consolidation on imaging was shorter (median, 43.0 days) versus in patients without consolidation (87.5 days; P = .02). Reticulations were associated with longer time to computed tomography after COVID-19 onset (median, 82 versus 23.5 days; P = .006).

Conclusions.—
ALI and SARS-CoV-2 RNA can be detected in patients with COVID-19 for many months. ALI may evolve into fibrotic interstitial lung disease.

A gestão de processos passou a ser uma questão importante para a sobrevivência das organizações e no setor público essa premissa não é diferente. Uma forma de atualizar a visão fundamentalista da tecnologia burocrática e ter como objetivo a arquitetura dos processos no cidadão é substituir a linha de produção pela visão do design de serviço. Este artigo tem como objetivo construir um macroprocesso de simplificação dos “processos dos serviços públicos”, suficientemente flexível e que possa ser utilizado em diferentes setores e organizações públicas. Aplica-se uma abordagem exploratória descritiva com base bibliográfica e documental para a construção do Macroprocesso Simplificado. O resultado encontrado foi um sistema construído de forma robusta e que atende de forma adequado o Marco Legal, regulamentando a simplificação dos processos de forma flexível, assim como pode ser customizada para diferentes setores da administração pública. O macroprocesso precisa ser customizado para dar conta das especificidades locais e é composto por quatro grandes ciclos, que precisam ser gerenciados e melhorados permanentemente. Não foram apresentados os indicadores de desempenho porque estes indicadores precisam ser construídos segundo as especificidades de cada setor e organização.
The Real World of College
Authors: Fischman Wendy , Gardner Howard 
Published: March 2022

Why higher education in the United States has lost its way, and how universities and colleges can focus sharply on their core mission.
For The Real World of College, Wendy Fischman and Howard Gardner analyzed in-depth interviews with more than 2,000 students, alumni, faculty, administrators, parents, trustees, and others, which were conducted at ten institutions ranging from highly selective liberal arts colleges to less selective state schools. What they found challenged characterizations in the media: students are not preoccupied by political correctness, free speech, or even the cost of college. They are most concerned about their GPA and their resumes; they see jobs and earning potential as more important than learning. Many say they face mental health challenges, fear that they don't belong, and feel a deep sense of alienation. Given this daily reality for students, has higher education lost its way? Fischman and Gardner contend that US universities and colleges must focus sharply on their core educational mission.
Fischman and Gardner, both recognized authorities on education and learning, argue that higher education in the United States has lost sight of its principal reason for existing: not vocational training, not the provision of campus amenities, but to increase what Fischman and Gardner call “higher education capital”—to help students think well and broadly, express themselves clearly, explore new areas, and be open to possible transformations. Fischman and Gardner offer cogent recommendations for how every college can become a community of learners who are open to change as thinkers, citizens, and human beings.
Light‐Directed Assembly of Colloidal Matter

Published: March 2022

AbstractThe assembly of colloidal particles into 2D or 3D superstructures is significant as the colloidal assembly exhibits collective behavior beyond the sum of single particles. Technically, colloidal particles can either self‐assemble when thermodynamic equilibrium is reached, or directed into specific assembly under external stimulus, such as electric, magnetic, acoustic, or light field. Specifically, light can be focused locally and manipulated in a precise manner, providing the possibility to tailor the assembly kinetics in different degrees of freedom. The understanding of light–matter interaction during the assembly process is challenging but critical for the design and fabrication of diverse colloidal superstructures. In this review, these particles are treated as artificial atoms at colloidal scale to mimic the organization of matter. From this aspect, the light‐directed assembly process is discussed on the basis of the roles of light, including light‐directed nucleation, diffusion, interparticle bonding, and phase control. Beyond what has been observed at atomic scale, colloidal atoms exhibit diversity in size, shape, and composition, and their bonding force is irrelevant to the electronic state, which enriches the geometric complexity of colloidal matter. Finally, the authors summarize the emerging applications of these colloidal superstructures in nanophotonics, nanocatalysis, and nanomedicine, and outline the major challenge and future development.
Multifunctional Ion‐Lock Interface Layer Achieved by Solid–Solid Contact Approach for Stabilizing Perovskite Solar Cells

Published: March 2022

AbstractIt has been a hindering issue in perovskite solar cells that the interfaces between the perovskite and charge transport layers show significantly high concentrations of defects with an amount about 100 times more than inside the bulk perovskite layer. The issue causes substantial reduction in both the efficiency and stability of the devices. Herein, a solid–solid contact approach is demonstrated to realize a multifunctional ion‐lock layer with strong chemical interaction to the perovskite layer. The multifunctional ion‐lock layer remarkably suppresses the interface defects and tunes the work function, contributing to promoting the carrier extraction, increasing the open‐circuit voltage, and enlarging the photocurrent. In addition, the multifunctional ion‐lock layer successfully locks ions from movement and thus improves the stability of the devices. Finally, with a multifunctional ion‐lock layer, the perovskite solar cells deliver an efficiency of up to 23.13% along with desirable long‐term operational, storage, and humidity stability. Consequently, the work offers guidelines for establishing defect‐suppressed interfaces between perovskites and hole transport layers.

Published: March 2022

AbstractSynergistic strategies by combining nanoreactors and prodrugs hold tremendous potential in anticancer treatment. However, precise death of target cancer cells remains a significant challenge due to the absence of an elaborate cancer targeting strategy. Here, a dual‐targeting approach that combines the action of H2O2‐producing folate receptor‐targeted nanoreactors with a cyclooxygenase‐2 (COX‐2) targeted prodrug is reported. A folate‐modified silica nanoreactor encapsulating glucose oxidase (GOX) is prepared to generate H2O2, which induces oxidative stress and allows the activation of the prodrug by targeted intracellular delivery. A novel prodrug bearing both COX‐2 targeting Celecoxib and SN‐38 anticancer agent with an H2O2‐cleavable thioketal linker to activate the drug is presented. By dual‐targeting, the generated H2O2 from GOX triggers the cleavage of a thioketal linker in the prodrug to produce the active form of the SN‐38 anticancer drug in cancer cells inducing synergistic cell death. This dual‐targeting strategy with a synergistic potency can aid in developing selective and effective anticancer therapeutics.

AbstractThe design and fabrication of dual‐channel charge transmission mode are crucial to developing highly effective photocatalysts. However, constructing double charge transfer paths by loading dual cocatalysts in a nanocomposite is still a great challenge. Here, hollow Co9S8 nanocages are utilized to design a hierarchical Co9S8/CdIn2S4/Pt heterostructure with dual‐channel for charge transfer, in which Co9S8 nanocages and Pt particles act as cocatalysts. Moreover, Co9S8 and CdIn2S4 form an atomic interfacial contact by intermediate sulfur atoms. Due to double‐channel charge transfer and atomic interfacial bonding, the Co9S8/CdIn2S4/Pt nanocages accelerate the photo‐induced carriers transfer and suppress the combination of electron–hole pairs. As a result, the Co9S8/CdIn2S4/Pt nanocages exhibit increased photocurrent density of 62.8 µA cm−2, far exceeding that of pristine Co9S8 (6.87 µA cm−2). The optimized Co9S8/CdIn2S4/Pt nanocages display excellent photocatalytic H2 in production rate of 13 426 µmol g−1 h−1 and high cyclic stability for water splitting.

AbstractColloidal all‐inorganic lead halide perovskite nanocrystals (LHP NCs) feature with tunable high‐efficiency photoluminescence from blue to red for optoelectronic applications but suffer from instability under water moisture, UV light illumination, high‐temperature shock, as well as oxygen erosion. Previous work to improve LHP NCs stability was mainly focused on either glass bulk sealed LHP quantum dots (QDs) with low quantum efficiency, or mesoporous silica matrixes confined LHP QDs with organic ligands still existing. Here, a facile, noncolloidal, ligand‐free LHP QDs growth with physical confinement is proposed by integrating the growth of perovskite QDs with the fabrication process of hydrophobic silica‐aerogel powders (SAPs). As a result, the as‐synthesized mono‐ and mixed‐cesium‐lead‐halide QDs @ SAPs composites show tunable photoluminescence from purple to deep red. Besides, the Pr3+ ions doped CsPbBr3 QDs @ SAPs composites exhibit moderate quantum efficiency, excellent stability under UV illumination, water moisture as well as temperature variation. Furthermore, performances of white LED device encapsulated Pr3+ doped composite with blue GaN chip and commercial red (Sr, Ca)AlSiN3:Eu2+ phosphor are evaluated. This work demonstrates a facile and general strategy for synthesizing high‐stable all‐inorganic cesium‐lead‐halide QDs for applications in white LED and display devices.

Published: March 2022

AbstractOptical metasurfaces have come into the spotlight as a promising platform for light manipulation at the nanoscale, including ultrafast all‐optical control via excitation with femtosecond laser pulses. Recently, dichroic metasurfaces have been exploited to modulate the polarization state of light with unprecedented speed. This work theoretically predicts and experimentally demonstrates by pump–probe spectroscopy the capability to reconfigure the ultrafast dichroic signal of a gold metasurface by simply acting on the polarization of the pump pulse, which is shown to reshape the spatio‐temporal distribution of the optical perturbation. The photoinduced anisotropic response, driven by out‐of‐equilibrium carriers and extinguished in a sub‐picosecond temporal window, is readily controlled in intensity by tuning the polarization direction of the excitation up to a full sign reversal. Hence, nonlinear metasurfaces are here demonstrated to offer the flexibility to tailor their ultrafast optical response in a fully all‐optically reconfigurable platform.

AbstractThe development of microfiltration (MF) membranes with a high separation flux and antifouling ability is an ultimate goal for the purification of emulsified oily wastewater by MF techniques. Herein, a dual‐functional MIL‐100(Fe)@graphene oxide (MIL‐100(Fe)@GO) membrane is fabricated by in situ growth of MIL‐100(Fe) with a graphene oxide (GO) nanosheet. The porous MIL‐100(Fe)@GO composite endows the MF membrane with superhydrophilicity and demulsification functions. The MIL‐100(Fe)@GO membrane achieves an outstanding water permeation flux of 12 457 L m−2 h−1 bar−1, as encouraged by the versatility of MIL‐100(Fe) in enabling superhydrophilicity of the MIL‐100(Fe)@GO membrane and providing rich water permeation channels. An impressive emulsion separation efficiency of >99% and maximum emulsion separation flux of 5529 L m−2 h−1 bar−1 are thus delivered by the MIL‐100(Fe)@GO membrane. Moreover, a 131% recovery ratio of emulsion separation flux (7135 L m−2 h−1 bar−1) is attained with this system after regeneration by ethanol. In virtue of the demulsification of MIL‐100(Fe), the rational design of the MIL‐100(Fe) hybrid membrane exhibits a self‐cleaning effect on the emulsion separation. The demonstrated high performance of the membrane system opens up new avenues for the development of membranes with antifouling abilities and ultrahigh flux for emulsion separation.

AbstractThe perovskite photovoltaic field has developed rapidly within a decade. In particular, formamidinium (FA)‐rich perovskite allows a broad absorption spectrum, and is considered to be one of the most promising perovskite materials. Great progress has been achieved, and most recorded high‐efficient perovskite solar cells (PSCs) used the FA‐rich perovskite light absorption layer. However, the black α‐phase formamidinium lead iodide (FAPbI3) perovskite easily transforms into an undesirable δ‐phase at a low temperature. Thus, researchers have put a lot of effort into deeply understanding the phase transformation and stabilization mechanism of FA‐rich perovskite. Herein, the fundamental physical properties of FAPbI3 materials, including crystal structure, phase‐transition temperature, charge‐carrier dynamics, etc. are summarized, and establish a complete phase evolution with temperature by reviewing previous reports. The intrinsic and external factors are subsequently discussed for influencing the stability of FAPbI3 perovskite and the remarkable breakthroughs of FA‐rich PSCs in recent years are reviewed. Moreover, a series of strategies to stabilize FA‐rich perovskite is summarized, including but not limited to compositional engineering, passivating engineering, processing engineering, and strain engineering. Finally, several new viewpoints are provided for improving the efficiency and stability of PSCs. This review may be regarded as a reference project for preparing high‐efficient and stable perovskite photovoltaic devices.

AbstractThermoelectric (TE) power generation is expected to be one of the most effective solutions to convert industrial exhaust heat to electricity for conserving fossil energy and reducing carbon emissions. However, its real application is obstructed decisively by the weakness of the service stability of state‐of‐the‐art TE materials at high temperatures in air. Refractory iron silicide (β‐FeSi2) used to be widely investigated as TE materials, but the low zT has restricted its practical application and even made it almost vanish from TE research in recent years. Here, guided by theoretical calculation, ultrahigh solubility of Ir on the Fe sites of β‐FeSi2 is successfully realized. Doping 16% Ir elicits multi‐valley electrical conduction and phonon‐electron scattering, doubling the previous zT record of β‐FeSi2 to ≈0.6 at 1000 K. The TE properties of the obtained β‐FeSi2 are practically unchanged after thermal aging in air at 1173 K. The new conceptual electrode‐less β‐FeSi2‐based refractory module demonstrates considerable power density and stable power generation when it is burned by a gas flame in air. These results mark a step toward developing practical TE power generation technology for the recovery of industrial waste heat.

AbstractThe study of the chiroptical properties of thin‐film samples of two chiral benzo[1,2‐b:4,5‐b’]dithiophene‐based oligothiophenes with optoelectronic properties was carried out at Diamond B23 beamline using the synchrotron radiation electronic circular dichroism imaging (SR‐ECDi) facility. The experimental results support the hypothesis that the non‐reciprocal circularly polarized absorption observed in these materials is due to the combined linear dichroism and linear birefringence contributions. The mapping at 50‐µM spatial resolution revealed that several species coexist in the mesoscopic chiral domains likely due to different aggregated phases, which were identified in the films by SR‐ECDi but could not be detected with benchtop ECD instruments.

Published: March 2022

AbstractAs the human population grows, the anthropogenic impacts from various agricultural and industrial processes produce unwanted contaminants in the environment. The accurate, sensitive and rapid detection of such contaminants is vital for human health and safety. Surface‐enhanced Raman spectroscopy (SERS) is a valuable analytical tool with wide applications in environmental contaminant monitoring. The aim of this review is to summarize recent advancements within SERS research as it applies to environmental detection, with a focus on research published or accessible from January 2021 through December 2021 including early‐access publications. Our goal is to provide a wide breadth of information that can be used to provide background knowledge of the field, as well as inform and encourage further development of SERS techniques in protecting environmental quality and safety. Specifically, we highlight the characteristics of effective SERS nanosubstrates, and explore methods for the SERS detection of inorganic, organic, and biological contaminants including heavy metals, pharmaceuticals, plastic particles, synthetic dyes, pesticides, viruses, bacteria and mycotoxins. We also discuss the current limitations of SERS technologies in environmental detection and propose several avenues for future investigation. We encourage researchers to fill in the identified gaps so that SERS can be implemented in a real‐world environment more effectively and efficiently, ultimately providing reliable and timely data to help and make science‐based strategies and policies to protect environmental safety and public health.
