AbstractDespite the intense progress of photodynamic and chemotherapy, however, they cannot prevent solid tumor invasion, metastasis, and relapse, along with inferior efficacy and severe side effects. The hypoxia‐responsive nanoprodrugs integrating photodynamic functions are highly sought to address the above‐mentioned problems and overcome the tumor hypoxia‐reduced efficacy. Herein, a hypoxia‐responsive tetrameric supramolecular polypeptide nanoprodrug (SPN‐TAPP‐PCB4) is constructed from the self‐assembly of tetrameric porphyrin‐central poly(l‐lysine‐azobenzene‐chlorambucil) (TAPP‐(PLL‐Azo‐CB)4) and an anionic water‐soluble [2]biphenyl‐extended‐pillar[6]arene (AWBpP6) via the synergy of hydrophobic, π–π stacking, and host–guest interactions. Upon laser irradiation, the central TAPP can convert oxygen to generate single oxygen (1O2) to kill tumor cells. Furthermore, under the acidic and PDT‐aggravated hypoxia tumor cell microenvironment, SPN‐TAPP‐PCB4 is rapidly disassembled, and then efficiently releases activated CB through the hypoxic‐responsive cleavage of azobenzene linkages. Both in vitro and in vivo biological studies showcase synergistic cancer‐killing actions between photodynamic therapy (PDT) and chemotherapy (CT) with negligible toxicity. Consequently, this supramolecular polypeptide nanoprodrug offers an effective strategy to design a hypoxia‐responsive nanoprodrug for a potential combo PDT‐CT transition.

Published: November 2023

AbstractHere, a strategy to strengthen d–p orbital hybridization by fabricating π backbonding in the catalyst for efficient lithium polysulfides (LiPSs) conversion is reported. A special interface structure of RuOx quantum dots (QDs) anchored on graphdiyne (GDY) nanoboxes (RuOxQDs/GDY) is prepared to enable strong Ru‐to‐alkyne π backdonation, which effectively regulates the d‐electron structures of Ru centers to promote the d–p orbital hybridization between the catalyst and LiPSs and significantly boosts the catalytic performance of RuOxQDs/GDY. The strong affinity with Li ions and fast Li‐ion diffusion of RuOxQDs/GDY also enable ultrastable Li metal anodes. Thus, S@RuOxQDs/GDY cathodes exhibit excellent cycling performance under harsh conditions, and Li@RuOxQDs/GDY anodes show an ultralong cycling life over 8800 h without Li dendrite growth. Lithium‐sulfur (Li–S) full cells with S@RuOxQDs/GDY cathodes and Li@RuOxQDs/GDY anodes can deliver an impressive areal capacity of 17.8 mA h cm−2 and good cycling stability under the practical conditions of low negative‐to‐positive electrode capacity (N/P) ratio (N/P = 1.4), lean electrolyte (E/S = 3 µL mg−1), and high S mass loading (15.4 mg cm−2).

Published: November 2023

AbstractThe high thermodynamic instability and side reactions of Zn‐metal anode (ZMA), especially at high current densities, greatly impede the commercialization of aqueous zinc‐ion batteries (AZIBs). Herein, a fluorine‐rich double protective layer strategy is proposed to obtain the high reversibility of AZIBs through the introduction of a versatile tetradecafluorononane‐1,9‐diol (TDFND) additive in aqueous electrolyte. TDFND molecule with large adsorption energy (−1.51 eV) preferentially absorbs on the Zn anode surface to form a Zn(OR)2− (R=−CH2−(CF2)7−CH2−) cross‐linking complex network, which balances space electric field and controls the Zn2+ ion flux, thus enabling the uniform and compact deposition of Zn (002) crystal planes. Meanwhile, TDFND with low Lowest unoccupied molecular orbital (LUMO, 0.10 eV) energy level is priorly decomposed to regulate the interfacial chemistry of ZMA by building a ZnF2‐rich solid electrode/electrolyte interface (SEI) layer. It is found that a 14 nm‐thick SEI layer delivers excellent structural integrity to suppress parasitic reactions by blocking the direct contact of active water and ZMA. Consequently, the Zn electrode exhibits a superior cycling life over 430 h at 10 mA cm−2 and a high average Coulombic efficiency of 99.8 % at 5 mA cm−2. Furthermore, a 68 mAh pouch cell delivers 80.3 % capacity retention for 1000 cycles.
Redox Out of the Box: Catalytic Versatility Across NAD(P)H‐Dependent Oxidoreductases

Published: November 2023

AbstractThe asymmetric reduction of double bonds using NAD(P)H‐dependent oxidoreductases has proven to be an efficient tool for the synthesis of important chiral molecules in research and on industrial scale. These enzymes are commercially available in screening kits for the reduction of C=O (ketones), C=C (activated alkenes), or C=N bonds (imines). Recent reports, however, indicate that the ability to accommodate multiple reductase activities on distinct C=X bonds occurs in different enzyme classes, either natively or after mutagenesis. This challenges the common perception of highly selective oxidoreductases for one type of electrophilic substrate. Consideration of this underexplored potential in enzyme screenings and protein engineering campaigns may contribute to the identification of complementary biocatalytic processes for the synthesis of chiral compounds. This review will contribute to a global understanding of the promiscuous behavior of NAD(P)H‐dependent oxidoreductases on C=X bond reduction and inspire future discoveries with respect to unconventional biocatalytic routes in asymmetric synthesis.
Changes in crosslinking structure of thermo‐oxidative aging chloroprene rubber and its effect on strain‐induced crystallization

Published: November 2023

AbstractChloroprene rubber (CR) is frequently quoted as an example of strain‐induced crystallizing elastomer. Many researchers have focused on studying the aging mechanism and mechanical properties of aged CR, little has been done on the effect of crosslinking structure on strain‐induced crystallization (SIC). The present paper related systematic investigations combining the changes of crosslinking structure and its influence on SIC. It was firstly investigated based on FTIR, crosslinking density test and GPC. The results showed that the molecular chains were oxidized in the early stage of aging, but the crosslinking reaction still dominated. At the same time, sol content and polydispersity decreased. In the later stage of aging, CR was oxidized, resulted in severe molecular chains fracture and an increase in the free sol content and polydispersity. The impact of aging on SIC under tensile condition was further investigated by the tensile tests. An obvious stress‐hardening was found for unaged CR, but not in aged CR. The crystallinity and microcrystalline region orientation tests showed that oxidation, crosslinking by double bonds and dechlorination during aging were not conducive to the orientation of molecular chains during stretching. It is the aging process that has an adverse effect on the SIC of CR.

Key Clinical MessageA very rare skin cancer. Malignant variant of pilomatricoma. It is unique because of its highly aggressive behavior. Responds poorly to chemotherapy and radiotherapy. Treated with a wide surgical excision with safe margins.AbstractPilomatrix carcinoma is uncommon and locally aggressive tumor of the hair follicle matrix. It is a malignant variant of pilomatricoma. If left untreated for a long time may attain massive size and has the potential for distant spread. Only few cases with brain extension have been reported in the literature. Diagnosis of these tumors is established by histopathology. Although pilomatrixoma and pilomatrix carcinoma are well‐recognized lesions, clinically they are frequently misdiagnosed as other skin conditions. The tumors respond poorly to chemotherapy and radiotherapy. Thus, recommended treatment is a wide surgical excision with safe margins. Herein, we report the case of a 39‐year‐old African woman with pilomatrix carcinoma of the scalp eroding the skull bone with intracranial extension.

AbstractObjectivesThe usefulness of 0.6% sodium alginate (SA) as a submucosal (SM) injection solution for endoscopic SM dissection (ESD) has gained attention over the past few years. However, using ESD for colorectal neoplastic lesions is not explicitly researched as yet. Thus, we conducted this study to determine the feasibility and safety of 0.6% SA solution for colorectal ESD.MethodsIn this single‐center, retrospective pilot study, a total of 100 cases treated with ESD using 0.6% SA as a SM injection solution for colorectal neoplasia at our institute were retrospectively reviewed to clarify the clinical feasibility and safety of 0.6% SA. The primary endpoint was to evaluate the complication rate, and the secondary endpoint was to determine the procedure time and the amount of solution used.ResultsIntraoperative perforation was observed in 1 case (1.0%), 2 cases (2.0%) presented with postprocedural hemorrhage, and no lethal adverse events were observed. The median ESD procedure times were 39.5 min (10–150), and the amount of solution used was less than 20 mL in 67 cases (67.0%). En‐bloc resection could be achieved in 97 cases (97.0%). Although six cases underwent subsequent surgery due to the deep SM invasion (>1000 μm), there were no cases with nodal involvement, confirmed through histopathological evaluation.ConclusionsOur findings indicate that 0.6% SA can potentially ensure safe and secure ESD for colorectal neoplasia.
The internal structure of spring mounds of Nefzaoua oasis in Tunisia: Formation of an original geomorphic structure
Authors: Raddadi Afef , Podwojewski Pascal 
Published: November 2023

AbstractSpring mounds are specific geomorphological landforms in arid or semi‐arid environments associated with playas and artesian springs. Spring mounds are found worldwide, especially in the great Artesian Basin of Australia and in North American and Egyptian deserts. They result from an exceptional succession of climatic, geomorphological and hydrogeological conditions, with processes that follow each other in a specific order. In Tunisia, in the arid zone, ca. 126 spring mounds have been identified in Nefzaoua province alone, especially in the oasis east of Chott el Jerid. They have a conical shape that ranges from 200 to more than 2000 m in diameter and 3–30 m tall, and their centre is hollowed out by an artesian spring of fresh water. Palm groves (Phoenix dactylifera) spread out at the foot of each mound. The springs have dried up because of the proliferation of borehole wells. Because of the low electric conductivity (EC) of the sediments (<1 mS cm−1) at their base, spring mounds have been excavated and used as a soil amendment to expand new palm plantations. This excavation allows for analysis of their internal structure, which has never been observed well. In the present study, fine analysis of sediment layers in four sections of two representative mounds showed that vegetation had trapped sediment at their base. Fine strata of variable texture alternating with variable calcium carbonate, gypsum or organic carbon contents suggest a clear limnic origin. Many redoximorphic features, sometimes associated with the presence of old roots, suggest variation in the water level in the centre of the mound. The mounds are capped by a thick layer of indurated gypsum, which helps them resist hydric and aeolian erosion. The origin of the sediment components is discussed.
Seeking outcomes under tight budgets: A case for health impact bonds in Post‐COVID times
Authors: Shiva Mehdi 
Published: November 2023

AbstractWith global public debt at record levels, governments are facing unprecedented challenges in providing essential health services. This exploratory study aims to assess the relevance of Health Impact Bonds (HIBs) as a means of financing preventative health services during times of fiscal constraint and in the aftermath of the COVID pandemic. The study draws on a review of the literature on HIBs, along with a case study analysis of HIBs implemented in the UK. The findings of the study indicate that, although HIBs offer promise as an innovative funding tool for preventative health services in tight fiscal situations, certain challenges are limiting their broader adoption.

Published: November 2023

AbstractTo meet the lightweight production requirements of automobiles and achieve high strength, reinforced thermoplastic composite materials are gradually replacing metal materials. Injection molding is the preferred manufacturing method to enable the production of complex‐shaped parts, facilitate production, and reduce costs. In this study, carbon fiber (CF) was added to the commonly used resin‐reinforcing material, polyamide (nylon) PA6, to create a CF‐reinforced thermoplastic composite (polyamide 6 [PA6]/CF) that was welded using injection molding. This study not only investigates the impact of different welding conditions on shear strength but also discusses the sequence of welding. Achieving 85% of the shear strength of the PA6 base material under ideal circumstances. The CF distribution and reinforcement mechanism were analyzed by observing the connection interface and cross section using a polarizing microscope and a scanning electron microscope. When PA6/CF was used as the secondary molded body, the welding results were better. The addition of CF had a significant strengthening effect on the strength of the PA6 injection welding.Highlights
Carbon fiber‐reinforced thermoplastic composite materials were prepared, and welding with PA6 was achieved using the injection molding method.
The optimal welding parameters were determined by varying the mold, injection speed, injection temperature, and order of injection. The maximum welding shear strength reached 85% of the base material shear strength.
The positive effect of specific fiber distribution on welding strength was analyzed by observing the interface using a scanning electron microscope and a polarizing microscope.
This study provides valuable insights into the optimization of welding processes for carbon fiber thermoplastic composite materials, offering possibilities for connecting dissimilar materials with poor compatibility.
2HDM interpretations of the CMS diphoton excess at 95 GeV
Authors: Azevedo Duarte , Biekötter Thomas , Ferreira P. M. 
Published: November 2023

AbstractIn both Run 1 and Run 2 of the LHC, the CMS collaboration has observed an excess of events in the searches for low-mass Higgs bosons in the diphoton final state at a mass of about 95 GeV. After a recent update of the experimental analysis, in which the full Run 2 data collected at 13 TeV has been included and an improved experimental calibration has been applied, the local significance of the excess amounts to 2.9σ. The presence of this diphoton excess is especially interesting in view of a further excess observed by CMS in ditau final states at a comparable mass and similar local significance. Moreover, an excess of events with about 2σ local significance and consistent with a mass of 95 GeV was observed in LEP searches for a Higgs boson decaying to pairs of bottom quarks. We interpret the CMS diphoton excess in combination with the ditau excess in terms of a pseudoscalar resonance in the CP-conserving two-Higgs-doublet model (2HDM). Furthermore, we discuss the possibility that, if CP-violation is taken into account, a CP-mixed scalar state can in addition describe the LEP result, thus accommodating all three excesses simultaneously. We find that the region of parameter space where both the CMS diphoton and ditau excesses can be fitted is in tension with current constraints from the flavour sector, potentially calling for other new-physics contributions to flavour-physics observables, most notably b → sγ transitions. Additionally, the new source of CP-violation violates electron EDM constraints by about an order of magnitude. We also comment on the compatibility with the recent ATLAS diphoton searches.
