AbstractBlack phosphorus (BP) has attracted great attentions in the last few years, but their applications in optoelectronics have been strongly hindered by the poor environmental stability, especially under light irradiation. Herein, the fabrication of surface passivated few‐layer BP assisted by polymer ionic liquids (PILs) is reported. The PIL‐modified 2D BP exhibits excellent stability under ambient conditions, with negligible deterioration in 100 d. Furthermore, the PILs attached on the BP surface provide reliable and flexible electrical contact between the few‐layer BP and other device components. As a proof of concept, PIL‐modified BP nanosheets are successfully applied in flexible photodetectors, which show high flexibility, good detectivity with no obvious performance deterioration in 120 h. This work demonstrates that the PIL modification can endow BP nanosheets with excellent environmental stability and good conductivity, so that may significantly expand the applications of BP in flexible optoelectronics.

AbstractUnevenly distributed dendrite growth is usually viewed as a consequence to the diffusion‐limited interface instability during electrodeposition, leading to one of the most serious obstacles hindering the application of high‐capacity lithium (Li) metal anodes. Herein, a fundamental issue of modifying Li plating behavior using a structure of 3D vertical graphene nanowalls on nickel (Ni) foam (VGN/Ni) is investigated. Such a structure exhibits a significant pseudocapacitive interfacial feature, greatly improving the Li+ ion transfer kinetic through the structure, and exhibiting uniform Li plating/stripping for stable Li metal cycling even at a high depth of discharge of 50%. Based on such a structure, high Coulombic efficiencies ≈97% and 99% can be obtained in carbonate and ether electrolyte over long‐term cycling. The symmetrical cell based on the VGN/Ni@Li composite anodes can afford a stable cycling of 2000 h with low voltage hysteresis of 30 mV. Full cell system using VGN/Ni@Li composite anode and LiFePO4 cathode is also proved, with high capacity retention of 89.4% at the 1000th cycle. The pseudocapacitance induced benefits, which have not yet been elucidated for Li metal anodes, can conduct to underlying strategy in designing stable Li metal host for high‐energy‐density batteries.

AbstractIonic liquids (ILs) electrolyte hold tremendous potentials to develop high‐energy‐density electric double layer capacitor due to their wide voltage windows, but are severely plagued by the sluggish mass diffusion from high viscosity and large ion size, particularly over micropore‐dominated carbon electrodes. Exploiting the carbon electrode possessing high compatibility with ILs electrolyte remains a great challenge. Herein, an emerging 3D cross‐coupled macro‐mesoporous carbon network with ultrahigh specific surface area (SSA, 2872.2 m2 g−1), N‐self doping, small‐sized mesopores (2–4 nm) and macropores (50–150 nm) is designed via a facile, versatile, and ecofriendly salt‐template strategy from the NaNO3‐gelatin biopolymer aerogel, which shows great adaptability toward high energy power density used in 4 V EMIBF4 ILs (92 Wh kg−1 is achieved at 1 kW kg−1, and notably a record high energy density of 39 Wh kg−1 is retained even at an ultrahigh power density of 200 kW kg−1). The large energy density is ascribed to the plentiful ion‐available mesoporous active sites (Smeso/SSA = 86.6%, Vmeso/Vtotal = 92.1%), while the extraordinary power density is attributed to the synergistic effects from the suitable macro‐mesoporous ion‐diffusion channels, continuous conductive network, low oxygen content (2.24%) as well as good affinity to ILs.

AbstractQuasi‐2D layered organometal halide perovskites have recently emerged as promising candidates for solar cells, because of their intrinsic stability compared to 3D analogs. However, relatively low power conversion efficiency (PCE) limits the application of 2D layered perovskites in photovoltaics, due to large energy band gap, high exciton binding energy, and poor interlayer charge transport. Here, efficient and water‐stable quasi‐2D perovskite solar cells with a peak PCE of 18.20% by using 3‐bromobenzylammonium iodide are demonstrated. The unencapsulated devices sustain over 82% of their initial efficiency after 2400 h under relative humidity of ≈40%, and show almost unchanged photovoltaic parameters after immersion into water for 60 s. The robust performance of perovskite solar cells results from the quasi‐2D perovskite films with hydrophobic nature and a high degree of electronic order and high crystallinity, which consists of both ordered large‐bandgap perovskites with the vertical growth in the bottom region and oriented small‐bandgap components in the top region. Moreover, due to the suppressed nonradiative recombination, the unencapsulated photovoltaic devices can work well as light‐emitting diodes (LEDs), exhibiting an external quantum efficiency of 3.85% and a long operational lifetime of ≈96 h at a high current density of 200 mA cm−2 in air.

Published: October 2018

AbstractHER2 and VEGF are closely related to the progression of several tumors. The inhibitor simultaneously targeting these two proteins will effectively inhibit the progression of tumors. Here, a bispecific antibody, termed as YY0411, targeting both HER2 and VEGF as a potent anticancer therapeutic antibody is reported. YY0411 is the first bispecific antibody constructed in IgG‐Decoy receptor format. It efficiently identifies and combines both HER2 and VEGF protein. YY0411 is believed to be a candidate tumor suppressor as it significantly inhibits the colony formation ability of human cancer cells (Calu‐3, MDA‐MB‐453, and NCI‐N87 cells). The phosphorylation of HER2 and VEGF downstream components are also decreased in these cells with the treatment of YY0411. Similar to other antibodies, YY0411 has the ability to promote the secretion of IFN‐γ by T lymphocytes. In addition, YY0411 significantly inhibits the growth of Calu‐3 cells‐induced xenograft in nude mice. This work demonstrates that YY0411 may be a potential anti‐lung cancer drug.

AbstractBiofilm formation induced by urease‐producing species can cause the increase of urine pH, and eventually lead to the blockage of catheters. In this study, a novel theranostic multilayer coating which combines both early visual warning of catheter blockage and antibacterial efficacy is described. The proposed coating comprised multilayered polymeric architecture using electrostatic self‐assembly (ESA) technique. In such a system, an inner layer of hydrogel PAA (poly (acrylic acid)) and middle layer of CS (chitosan) are employed to encapsulate an antibiotic delivery system that has sensitive colorimetric transition response upon pH elevation. The two layers are sealed and capped by a pH‐response layer of EUDRAGITS 100. The proposed coating sensor hydrogel exhibits chromatic color transitions (blue–purple–red) upon bacterial infection and provides an indication for both initial bacterial infection and subsequent blockage. Meanwhile, encapsulation of antimicrobials increases the amount of antibiotic resident in the vicinity of bacteria in residual urine solution and thus inhibiting bacterial growth.

AbstractThe reduced titanium oxide (TinO2n‐1, 4 ≤ n ≤ 10) material system has attracted considerable attention due to their unique crystal structure and excellent electrical and chemical properties. Interface science and engineering play a very important role in both the synthesis or usage of such material, not only because the commonly observed multiphase coexistence phenomenon during the preparation process, but also due to the special physical and chemical properties brought by the heterogeneous interfaces. The lack of research on the interface structures as well as their influence on the properties seriously hinders the development of TinO2n‐1. In this work, crystallographic model is employed first to predict the crystallographic features of Ti5O9/Ti4O7 interface in titanium oxide nanosystems. The initial lattice correspondence is determined after fully considering the crystal symmetry and structures of Ti5O9 and Ti4O7. To verify the predicted results, Ti5O9/Ti4O7 nanocomposites are prepared through carbothermal reduction reaction, followed by detailed X‐ray diffraction and transmission electron microscopy characterizations. The observed orientation relationships between Ti5O9 and Ti4O7 are consistent with the predicted results, which confirm the application of crystallographic model in the phase transformation in which chemical reaction involved.

Published: October 2018

AbstractFiber‐based wearable healthcare sensing devices that can monitor the health status of the human body in real time can be affected by sweat from the human body or water from the outside, which may cause the sensor to malfunction. In this study, it is investigated how the fiber strain sensor can operate stably without being affected by sweat or water, even if no additional passivation layer is formed on the outside of fibers applicable to wearable healthcare sensors. The resistance values ​​of the microfiber strain sensor are monitored in real time with the movement of the elbow and knee wraps stitched with a polyurethane (PU)–tin oxide (SnO2)–carbon nanotube (CNT) composite microfiber. The PU used as a matrix plays a role of naturally increasing or decreasing the fiber according to the movement of the elbow or knee of the body. The CNTs embedded in a PU matrix can monitor the angular movement of the elbow and knee by measuring the changes in electrical resistance. The (1H,1H,2H,2H‐heptadecafluorodec‐1‐yl) phosphonic acid‐coated SnO2 embedded in a PU prevents sweat and water from entering the fiber. This allows to precisely detect elbow and knee movements stably in an external environment exposed to sweat or water.

Published: October 2018

AbstractOrganic vapor‐jet printing (OVJP) is an ink‐free printing method for organic thin films wherein a thermally generated vapor of organic small molecules is jetted through a nozzle by inert carrier gas. OVJP holds a great promise because it uses a field‐proven small‐molecular technology as it yet keeps the benefits of jet printing methods such as being mask‐free, easily scalable, and frugal in material usage. However, fabrication on plastic substrates with OVJPs is challenging due to the excessive heat from the nozzle, preventing its use for flexible electronics. Thermal damage issues in the OVJP are particularly of problem because its nozzle should be close to a substrate for high‐resolution patterning. Here, a simple yet highly effective method is proposed to reduce the radiant heat transfer from the nozzle and thereby enable fabrication of flexible organic devices. Upon application of an electroplated gold layer on the nozzle as a low‐emissivity coating, the temperature of a substrate underneath the nozzle gets significantly reduced below its glass‐transition temperature. A flexible organic light‐emitting diode signage device and an active‐matrix tactile sensor patch are demonstrated on plastic substrates with the proposed approach, demonstrating its feasibility in unlocking the full potential of OVJP methods.

AbstractFlexible perovskite solar cells (PeSCs) hold great potential as a leading technology for large‐scale roll‐to‐roll production of highly efficient renewable energy sources. To achieve long‐term bendability and competitive photovoltaic properties for flexible PeSCs, an efficient strategy is reported for a fully indium‐free flexible composite electrode, consisting of solution‐processed silver nanowires (AgNWs) conductive network, a sol–gel‐derived ZnO protective layer for smoothing the surface, and an atomic‐layer‐deposited TiO2 passivation layer for eliminating the perovskite decomposition. The synergetic interplay of this electrode stack results in good electrical conductivity, optical transparency, mechanical robustness, and low‐temperature processability. With collective optimization of this composite electrode, flexible PeSCs on plastics realize a power conversion efficiency of 17.11%, which is comparable to that of conventional indium‐tin‐oxide‐based device (18.26%). Moreover, flexible PeSCs using this composite electrode are repeatedly bendable, retaining 77% of their initial efficiency after 2000 bending cycles at a radius of 6 mm. Because of the ease of use and remarkable improvement in efficiency, this flexible composite electrode will help to enable the low‐cost roll‐to‐roll processing of flexible PeSCs.

AbstractThe increased need for pure and safe water has motivated many researchers and scientists to pay more attention for clearing the colored water from the toxic dyes. This study is based on the production of a novel hydrogel by the free radical‐induced polymerization of acrylamide (AAm) and acrylic acid (AA) with 3‐Allyloxy‐2‐hydroxy‐1‐propanesulfonic acid sodium salt (AHPS) using the radical initiator, benzoyl peroxide, and the multifunctional cross‐linker, Pentaerythritol Tetraallyl Ether(PTE). Confirmation of synthesis was done by aid of the Fourier transform infrared spectra, energy‐dispersive X‐ray, and the scanning electron microscope (SEM). SEM micrographs indicated the three‐dimensional cross‐linked structure of the hydrogels. The thermal properties were evaluated via the thermal gravimetric analysis. The swelling percentage and swelling kinetic parameters were determined. It was found that swelling of P(AAm‐AA‐AHPS) hydrogels was reached to 7,071% in distilled water, while P(AAm‐AA) hydrogels swelled 1,055%. And the swelling percentage was found to be affected by pH of the surrounding medium. The AHPS‐based hydrogel giving the greatest swelling % was tested as a methylene blue remover from the aqueous solution by the batch adsorption method. Studying the adsorption kinetics and isotherm showed that the pseudo‐second‐order and the Freundlich model described well the adsorption process, and the highest adsorption capacity reached 79.42 mg/g.

Published: October 2018

AbstractThe potassium‐ion battery (PIB) represents a promising alternative to the lithium‐ion battery for large‐scale energy storage owing to the abundance and low cost of potassium. The lack of high performance anode materials is one of the bottlenecks for its success. The main challenge is the structural degradation caused by the huge volume expansion from insertion/extraction of potassium ions which are much larger than their lithium counterparts. Here, this challenge is tackled by in situ engineering of a yolk–shell FeS2@C structure on a graphene matrix. The yolk–shell structure provides interior void space for volume expansion and prevents the aggregation of FeS2. The conductive graphene matrix further enhances the charge transport within the composite. The PIB fabricated using this anode delivers high capacity, good rate capability (203 mA h g−1 at 10 A g−1), and remarkable long‐term stability up to 1500 cycles at high rates. The performance is superior to most anode materials reported to date for PIBs. Further in‐depth characterizations and density functional theory calculations reveal that the material displays reversible intercalation/deintercalation and conversion reactions during cycles, as well as the low diffusion energy barriers for the intercalation process. This work provides a new avenue to allow the proliferation of PIB anodes.

Published: October 2018

AbstractInterstitial deletions of chromosome 9q31 are very rare. The deletions in most reported patients have been detected by conventional cytogenetics, with reported breakpoints ranging between 9q21 and 9q34. Therefore, an accurate description of a “9q31 deletion syndrome” could not be established. However, based on microarray studies, a small region of overlap has recently been proposed.We report clinical features of two unrelated individuals with overlapping 9q deletions identified by SNP microarray analysis. Patient 1 has a 9 Mb deletion, while Patient 2's deletion was 21.6 Mb. The clinical features common to our patients and those in the literature include developmental delay and short stature. Patient 2 shows additional features not reported in other 9q31 deletions, such as hearing loss, ventriculomegaly, cleft lip and palate, and small kidneys, which could be due to the larger size of the deletion, hence the influence of the genes in the region beyond the smallest region of overlap.Based on the comparison of these patients with the previously reported patients, we redefine the smallest region of overlap and characterize the clinical features of the 9q31 deletion syndrome.

Published: October 2018

AbstractDarier disease (DD) is an autosomal dominant skin disorder caused by mutations in ATP2A2 encoding the sarco/endoplasmic reticulum Ca2+ ATPase Isoform 2 (SERCA2). Evidence of a population‐level association between DD and psychiatric disorders suggests that mutations in ATP2A2 may have pleiotropic effects on the brain as well as skin. Evidence of genotype–phenotype relationships between ATP2A2 mutations and neuropsychiatric phenotypes would further support this suggestion. We investigated genotype–phenotype correlations between lifetime neuropsychiatric features and ATP2A2 mutation type (dichotomized into likely gene disrupting [LGD] or protein altering) in 75 unrelated individuals with DD. We also looked for evidence of clustering of mutations within SERCA2 according to neuropsychiatric features. Combining our data with the existing literature, the rate of LGD mutations was found to be significantly higher among DD cases/families with bipolar disorder, schizophrenia, or affective psychosis (p = .011). We also found a significant relationship between mutations located in the S4–M4 region of the protein and the presence of a severe neuropsychiatric phenotype (p = .032). Our findings add support to the hypothesis that Darier‐causing mutations in ATP2A2 confer susceptibility to neuropsychiatric dysfunction, in particular severe psychiatric illness. This, together with evidence from research on common polymorphisms confirms ATP2A2 as a gene at which variation influences susceptibility to major psychiatric illness.
