AbstractGarnet‐type Li6.4La3Zr1.4Ta0.6O12 (LLZ) electrolyte is a promising candidate for high‐performance solid‐state batteries, while its applications are hindered by interfacial problems. Although the utilization of functional coatings and molten lithium (Li) effectively solves the LLZ interfacial compatibility problem with Li metal, it poses problems such as high cost, high danger, and structural damage. Herein, a mixed conductive layer (MCL) is introduced at the LLZ/Li interface (RT‐MCL) via an in situ cold bonding process at room temperature. Such a stable and compact RT‐MCL can effectively suppress side reactions and protect the crystal structure of LLZ, and it also inhibits growth of Li dendrites and promotes uniform Li deposition. The critical current density (CCD) of the Li symmetric cell composed of RT‐MCL‐LLZ is increased to 1.8 mA cm‐2 and provides stable cycling performance over 2000 h under 0.5 mA cm‐2. Additionally, this in situ cold bonding treatment can significantly reduce cost and eliminate potential safety issues caused by the high‐temperature processing of Li metal. This work highlights tremendous potential of this cold bonding technique in the reasonable design and optimization of the LLZ/Li interface.

AbstractTime delay lighting offers an added period of buffer illumination for human eyes upon switching off the light. Long‐lifetime emission from triplet excitons has outstanding potential, but the forbidden transition property due to the Pauli exclusion principle makes them dark, and it stays challenging to develop full‐color and bright triplet excitons. Herein, triplet excitons emission from ultraviolet (UV) to near infrared (NIR) in carbon nanodots (CNDs) is achieved by confining multicolor CNDs emitters in NaCNO crystal. NaCNO crystal can isolate the CNDs, triplet excitons quenching caused by the excited state electrons aggregation induced energy transfer is suppressed, and the confinement crystal can furthermore promote phosphorescence of the CNDs by inhibiting the dissipation of the triplet excitons due to non‐radiative transition. The phosphorescence from radiative recombination of triplet excitons in the CNDs covers the spectral region from 300 nm (UV) to 800 nm (NIR), the corresponding lifetimes can reach 15.8, 818.0, 239.7, 168.4, 426.4, and 127.6 ms. Furthermore, the eco‐friendly luminescent lampshades are designed based on the multicolor phosphorescent CNDs, time delay light‐emitting diodes are thus demonstrated. The findings will motivate new opportunities for the development of UV to NIR phosphorescent CNDs and time delay lighting applications.

AbstractThe culprits of atherosclerosis are endothelial damage, local disorders of lipid metabolism, and progressive inflammation. Early atherosclerosis is typically difficult to diagnose in time due to the lack of obvious symptoms, thus missing the best period of treatment. In this work, a π‐conjugated polymer (PMeTPP‐MBT) based on 3,6‐bis(4‐methylthiophen‐2‐yl)‐2,5‐bis(2‐octyldodecyl)pyrrolo[3,4‐c]pyrrole‐1,4(2H,5H)‐dione is designed as a novel photoacoustic contrast agent. On this basis, an intelligent responsive theranostic nanoplatform (PA/ASePSD) combining astaxanthin and SS‐31 peptide and loading with PMeTPP‐MBT is developed. The high affinity between the dextran shell with the broken endothelial surface VCAM‐1 and CD44 confers active targeting of PA/ASePSD to atherosclerotic lesions. High levels of ROS in the acidic plaque microenvironment act as an intelligent cascade switch to achieve controlled release of astaxanthin, SS‐31 peptide, and PMeTPP‐MBT for non‐invasive photoacoustic diagnosis, as well as plaque inhibition mediated by anti‐inflammation and multichannel regulation (including ABCA1, ABCG1, CD36, and LOX‐1) of lipid metabolism. Both in vitro and in vivo evaluations confirm the impressive anti‐atherosclerotic capability and the accurate photoacoustic diagnosis of PA/ASePSD nanoparticles, thus promising a candidate for early‐stage atherosclerosis theranostics.
Sustainable Drag Reduction of Fatty Acid Amide‐Based Oleogel Surface Under High‐Speed Shear Flows
Authors: Hameed Ali Zain , Lee Sang Joon 
Published: February 2023

AbstractNepenthes alata‐inspired micro/nano‐textured lubricant‐infused surface (LIS) has shown strong potential in the fields of drag reduction (DR), anti‐biofouling, and self‐cleaning. However, its surface‐slippery property is largely degraded under turbulent shear flow conditions due to the loss of the impregnated oil. This condition inhibits its practical applications to marine vehicles. The mucus‐impregnated tissue systems of marine creatures are primarily based on fatty acid amides (FAAs), such as erucamide or oleamide, which have been commercially utilized as solid‐slip additives. A stable lubricant interface of erucamide‐PDMS composite (EPC) oleogel is formed by cross‐linking erucamide with PDMS gel network prior to infusion of silicon oil. In this study, the surface stability and lubricant retention of EPC are investigated in consideration of DR applications. The fabricated EPC‐oleogel surface exhibits shear stable DR under harsh conditions, such as high pressure, temperature, and shear flow conditions. The surface shows a shear stable DR performance of about 14% even up to a high‐speed flow of 12 ms−1, corresponding to friction Reynolds number (Reτ) of approximately 5000. The superior lubrication stability of FAA‐oleogel at the flow conditions of cruising ships ensures its strong potential for sustainable fuel economy of marine vehicles.

AbstractThe numerous hierarchical architectures of 2D assemblies endow them with a new dimension to realize novel properties. From theoretical perspective, freedoms stem from in‐plane and out‐plane mechanical properties of 2D materials separately, which makes 2D materials embrace more than one “persistence length” giving rise to the diverse morphologies. However, the understanding of 3D architecture formation in 2D assemblies is still in its infancy. In fact, there is even no theoretical classification or reference to help clarify structural difference among numerous experimental obtained 2D assemblies. Based on the theoretical model composed by 2D sheets and Lennard‐Jones liquids, solution concentration dependence of 2D materials conformation is systematically studied, and a ln K behavior is uncovered that can realize the theoretical conformation prediction of 2D materials. More importantly, the digital production line (solution processing procedure) is set up toward establishing the 2D assemblies’ digital factory. The obtained structures may provide a reference to 2D assemblies, which benefits the understanding of the structural difference among different experiments and even help to guide the experimental design of 2D assemblies with targeted architectures and properties.

AbstractRed‐emitting narrow‐band phosphors are of utmost importance for next‐generation white‐light phosphor‐converted light‐emitting diodes (pc‐wLEDs) for improved efficacy and optimized correlated color temperatures. A promising representative crystallizing in an ordered variant of the UCr4C4 structure type is Sr[Li2Al2O2N2]:Eu2+ (SALON:Eu2+) emitting at a desirable wavelength of 614 nm. Despite an expected eightfold coordination of the Eu2+ ions by four N3− and O2− ions, respectively, the exact local coordination symmetry and a 1:1 ratio between the two types of ligands is not straightforwardly proven by X‐ray diffraction. Low‐temperature luminescence spectroscopy in conjunction with ligand field theory are powerful alternatives to resolve local features of Eu2+ as its excited 4f65d1 configuration reacts sensitively to the polarity of the ligands. The dominant emission at 614 nm shows pronounced vibronic fine structure at 10 K. In addition, weak emission bands can be resolved at 570 and 650 nm even at a low doping concentration of 0.5 mol% and are assigned to Eu2+ ions being eightfold coordinated by N3− and O2− ions in a ratio different from 1:1. Due to the feature of vierer ring‐type channels in SALON:Eu2+, those Eu2+ centers are sufficiently close for mutual energy transfer, which is characterized by time‐resolved luminescence at 10 K.

AbstractFlexible integrated photonics is an essential technology for emerging applications, including flexible optical interconnects, optogenetic stimulation, and implantable conformal sensing. Here, a novel and universal route for fabricating flexible photonic components with high‐refractive‐index contrast is reported. Central to such a unique method is the utilization of germanium oxide (GeO) as the sacrificial layer for releasing nanostructures from rigid substrates to flexible substrates. Various high‐quality inorganic optical materials can be grown directly on GeO by different thin‐film deposition methods due to its resistance to both high temperature and high‐power oxygen plasmas. In addition to the absence of restrictions on the material choices and integration processes for flexible photonic structures, the approach uses water as the etchant to remove the sacrificial layer, which has minimal impact on the optical performance of the photonic structures. Using this approach, a strain‐insensitive/sensitive microring resonator based on plasma‐enhanced chemical vapor deposited silicon nitride and reactive sputtered titanium oxide, respectively, is demonstrated, establishing the strategy as a facile and universal route for the fabrication of high‐index‐contrast flexible integrated photonic devices with various functionalities.

AbstractL‐Methionine is the unique sulfur‐containing amino acid essential for humans and animals, which is widely used in pharmaceutical, food and feed industries. Its green and efficient production has attracted a great deal of attention. Fermentation‐enzymatic coupling route is regarded to be promising for L‐methionine biosynthesis, while O‐succinyl‐L‐homoserine mercaptotransferase (MetZ) is the key biocatalyst. Exploring and engineering of MetZ with ideal catalytic properties is highly desired. Herein, the MetZ from Chromobacterium violaceum (CvMetZ) was screened and through in silico analyses, potential beneficial amino acid residues both at the access channel and around the oxygen anion holes were anchored for site‐saturation mutagenesis. The positive mutants were obtained with improved activity for L‐methionine biosynthesis using O‐succinyl‐L‐homoserine (OSH) and methyl mercaptan as substrate. The best mutant was further applied for L‐methionine production and supply of methyl mercaptan was optimized in a fed‐batch approach. The conversion of 100 g/L OSH reached 92% with L‐methionine yield of 62.6 g/L, which was well coupled with the OSH fermentation level.magnified image

AbstractImmune checkpoint blockade based on antibodies has shown great clinical success in patients, but the transitory working manner leads to restricted therapeutic benefits. Herein, a genetically engineered adenovirus is developed as the vector to deliver CRISPR/Cas9 (sgCas9‐AdV) to achieve permanent PD‐L1 gene editing with efficiency up to 78.7% exemplified in Hepa 1‐6 liver cancer cells. Furthermore, the sgCas9‐AdV is loaded into hydrogel made by silk fiber (SgCas9‐AdV/Gel) for in vivo application. The silk‐gel not only promotes local retention of sgCas9‐AdV in tumor tissue, but also masks them from host immune system, thus ensuring effectively gene transduction over 9 days. Bearing these advantages, the sgCas9‐AdV/Gel inhibits Hepa 1‐6 tumor growth with 100% response rate by single‐dose injection, through efficient PD‐L1 disruption to elicit a T cell‐mediated antitumor response. In addition, the sgCas9‐AdV/Gel is also successfully extended into other refractory tumors. In CT26 colon tumor characterized by poor response to anti‐PD‐L1, sgCas9‐AdV/Gel is demonstrated to competent and superior anti‐PD‐L1 antibody to suppress tumor progression. In highly aggressive orthotopic 4T1 mouse breast tumor, such a therapeutic paradigm significantly inhibits primary tumor growth and induces a durable immune response against tumor relapse/metastasis. Thus, this study provides an attractive and universal strategy for immunotherapy.

AbstractEpitaxial heterostructures of colloidal lead halide perovskite nanocrystals (NCs) with other semiconductors, especially the technologically important metal chalcogenides, can offer an unprecedented level of control in wavefunction design and exciton/charge carrier engineering. These NC heterostructures are ideal material platforms for efficient optoelectronics and other applications. Existing methods, however, can only yield heterostructures with random connections and distributions of the two components. The lack of epitaxial relation and uniform geometry hinders the structure–function correlation and impedes the electronic coupling at the heterointerface. This work reports the synthesis of uniform, epitaxially grown CsPbBr3/CdS Janus NC heterostructures with ultrafast charge separation across the electronically coupled interface. Each Janus NC contains a CdS domain that grows exclusively on a single {220} facet of CsPbBr3 NCs. Varying reaction parameters allows for precise control in the sizes of each domain and readily modulates the optical properties of Janus NCs. Transient absorption measurements and modeling results reveal a type II band alignment, where photoexcited electrons rapidly transfer (within ≈9 picoseconds) from CsPbBr3 to CdS. The promoted charge separation and extraction in epitaxial Janus NCs leads to photoconductors with drastically improved (approximately three orders of magnitude) responsivity and detectivity, which is promising for ultrasensitive photodetection.

AbstractChiral metal‐organic frameworks (MOFs) are usually endowed by chiral linkers and/or guests. The strategy using chiral secondary building units in MOFs for solving the trade‐off of circularly polarized luminescence (CPL)‐active materials, high photoluminescence quantum yields (PLQYs) and high dissymmetry factors (|glum|) has not been demonstrated. This work directionally assembles predesigned chiral silver clusters with ACQ linkers through reticular chemistry. The nanoscale chirality of the cluster transmits through MOF's framework, where the linkers are arranged in a quasi‐parallel manner and are efficiently isolated and rigidified. Consequently, this backbone of chiral cluster‐based MOFs demonstrates superb CPL, high PLQYs of 50.3%, and |glum| of 1.2 × 10−2. Crystallographic analyses and DFT calculations show the quasi‐parallel arrangement manners of emitting linkers leading to a large angle between the electric and magnetic transition dipole moments, boosting CPL response. As compared, an ion‐pair‐direct assembly without interactions between linkers induces one‐ninth |glum| and one‐sixth PLQY values, further highlighting the merits of directional arrangement in reticular nets. In addition, a prototype CPL switching fabricated by a chiral framework is controlled through alternating ultraviolet and visible light. This work is expected to inspire the development of reticular chemistry for high‐performance chiroptical materials.
Interfacial Issues and Modification of Solid Electrolyte Interphase for Li Metal Anode in Liquid and Solid Electrolytes
Authors: Chae Oh B. , Lucht Brett L. 
Published: February 2023

AbstractThe high energy density required for the next generation of lithium batteries will likely be enabled by a shift toward lithium metal anode from the conventional intercalation‐based anode such as graphite. However, several critical challenges for Li metal originate from its highly reactive nature and the hostless reaction of deposition and stripping impede the practical use of Li metal as an anode. The role of the solid electrolyte interphase (SEI) is very important for the Li metal anode where the SEI must protect the dynamically changing surface of the Li metal. Since the SEI‐generating reaction mechanisms for the two different electrolyte systems, liquid and solid, are considerably different, the SEI layers formed between the Li metal and the electrolytes in the two electrolyte systems have substantially different properties, causing different interfacial issues. Inhibition of the interfacial problems requires different strategies to reinforce the SEI layer for each of the electrolyte systems. However, the differences in the two electrolyte systems have not been clearly compared in the prior literature. In this report, the interfacial issues for the two different electrolyte systems are compared and different strategies for SEI modification are provided to overcome the issues.

AbstractNanocomposite solid polymer electrolytes are considered as a promising strategy for solid‐state lithium metal batteries (SSLMBs). However, the randomly dispersed fillers in the polymer matrix with limited Li+transference number and insufficient ionic conductivity severely sacrifice the ion transport capacity, thus restricting their practical application. To tackle these issues, a magnetic field‐assisted alignment strategy is proposed to disperse the vertically aligned akaganéite nanotube in the polymer matrix as an inorganic‐polymer nanocomposite solid‐state electrolyte for ultra‐stable SSLMBs. The metal cations as Lewis acid sites can grab anions to promote the dissociation of Li salts while the sufficient oxygen and hydroxyl functional group offer abundant Li‐ion migration sites for favored ion transportation. At the same time, the vertically aligned akaganéite/polymer interface combined with the above synergistic effects can establish oriented channels inside solid‐state electrolyte, which significantly elevates its ionic conductivity. Specially, an organic‐inorganic dual‐layer solid‐electrolyte interface is formed to uniform Li deposition and suppress the dendrite growth. The beneficial effect of the vertically aligned network is also demonstrated in full cell and pouch cell where remarkable 2000 cycles with a capacity decay of 0.012% per cycle can be achieved.

AbstractObjectivesThe main objective of this study is to understand how diet affects performance and cardiovascular health in a group of women participating in a demanding aerobic race such as marathon, compared to men.MethodsFifteen women participating in the Barcelona Marathon‐2016 were recruited to participate in the study. A group of men (n = 15) that performed the same marathon race was selected. Anthropometric parameters and diet records were collected before the race. Circulating parameters were analyzed 24 h‐pre‐race, immediately after the race and 48 h‐post‐race. These included certain minerals, lipid profile, muscle damage, inflammatory and cardiovascular health markers.ResultsDiets were very similar in the men and women, with inadequate amounts of carbohydrates and proteins for endurance events. Creatine kinase (CK; a muscle damage marker) and C‐reactive protein (CRP; a marker of inflammation) remained elevated 48 h post‐race in all participants, but was significant in women (641 vs. 143 U/L for CK and 5.8 vs. 0.7 mg/dL for CRP). Cardiac markers (high sensitivity troponin T (Hs‐TnT), suppression of tumorigenicity and N‐terminal pro B‐type natriuretic peptide) increased post‐race and returned to pre‐race values after 48 h in men and women. In particular, Hs‐TnT (marker of myocyte stress) increased from 2.2 to 62.5 ng/L post‐race in women and from 3.1 to 52.9 ng/L in men. Finally, circulating lipid parameters were at borderline unhealthy levels in both sexes.ConclusionStructural and functional cardiac advantages that women display compared to men in aerobic efforts are not manifested when diet is not adequately designed.
