Authors: He Qiang , Wang Kun , Li Dongke , Yang Deren , Pi Xiaodong 
Published: February 2024

AbstractTunable emission wavelength and excellent biocompatibility have positioned silicon quantum dots (Si QDs) as important optoelectronic materials in areas like displays, lighting, and biomedical imaging. However, the challenges of low luminescence efficiency impede the utilization of Si QDs, restraining the advancement of Si QDs‐based light‐emitting diode (LED) devices. This study primarily concentrates on optimizing the surface structure of Si QDs and refining the Si QDs‐based LED device structures. A strategy involving active oxidation followed by hydrofluoric etching and hydrosilylation is proposed to enhance the optical characteristics of Si QDs. A variety of characterization methods are employed to evaluate the impact of the active oxidation on the photoluminescence and surface structures of Si QDs. This approach ultimately achieves an impressive enhancement in the photoluminescence quantum yield (PL QY) of Si QDs from 6.7% to 60.3%. Furthermore, the atmospherically oxidized Si QDs with the highest PL QY are selected as the emitting‐layer material to fabricate LEDs with the structure of ITO/PEDOT:PSS/TFB/Si QDs/ZnMgO/Ag. The introduction of ZnMgO effectively balances charge injection in the Si‐QDs‐based LEDs. As a result, the devices achieve electroluminescence with an external quantum efficiency of 13.2%.

AbstractParkinson's disease (PD) is a common chronic central nervous system disorder that reduces quality of life and increases mortality. Currently, the treatment of PD is limited due to the challenge of macromolecular drugs crossing the blood‐brain barrier (BBB). Black phosphorus (BP) has antioxidant and anti‐inflammatory effects and shows potential for neuroprotection. To solve the restriction of the BBB, innovative BP microbubbles (BP@MBs) combined with focused ultrasound (FUS) are constructed to facilitate BBB opening. Additionally, the biocompatibility and safety of BP@MBs with varying dimensions are investigated, including BP quantum dot microbubbles (BPQDs@MBs) and BP nanosheet microbubbles (BPNSs@MBs). The findings indicate that low concentrations of BP have good biosafety and that BPQDs@MBs exhibit better biocompatibility than BPNSs@MBs both in vitro and in vivo at the same concentrations. Moreover, a 6‐hydroxydopamine (6‐OHDA)‐induced PD cell model and an animal model are established to verify the anti‐PD effects of BPQDs@MBs and BPNSs@MBs. The results confirmed that BPQDs@MBs and BPNSs@MBs have antioxidant effects that reduced neuronal apoptosis and improved the motor symptoms of PD in rats. BPQDs@MBs combined with FUS may be a promising option for the clinical treatment of PD.

AbstractNickel‐rich layered oxides are a class of promising cathodes for high‐energy‐density lithium‐ion batteries (LIBs). However, their structural instability derived from crystallographic planar gliding and microcracking under high voltages has significantly hindered their practical applications. Herein, resurfacing engineering for single‐crystalline LiNi0.83Co0.07Mn0.1O2 (SNCM) cathode is undertaken. A passivation shell, comprising a surface fast ion conductor Li1.25Al0.25Ti1.5O4 (LATO) layer and a near‐surface confined cation hybridization region, is established through co‐infiltrating Al and Ti into SNCM, which can profoundly improve structural stability. Compelling evidences show that high‐conductivity LATO‐overcoat facilitates Li+ conduction and resists electrolyte attack. The introduction of strong Al─O bonds and resurfacing regions stabilize bulk and near‐surface lattice oxygen respectively during cycling, thus hindering the formation of oxygen vacancies and the occurrence of detrimental phase transformations, ultimately suppressing the crystallographic planar gliding and nanocracking. Subsequently, the modified SNCM drastically outperforms the baseline SNCM, exhibiting an ultrahigh 88.9% retention rate of original capacity at 1.0C after 400 cycles, and a discharge capacity of 146.8 mAh g−1 with a 92.6% capacity retention rate after 200 cycles at 5.0C within a voltage window of 2.7–4.3 V. The promising performance demonstrated by the multifunctional surface coating highlights a new way to stabilize Ni‐rich cathodes for LIBs.

Published: February 2024

AbstractInsects are covered with free neutral cuticular hydrocarbons (CHC) that may be linear, branched, and unsaturated and vary in their chain length. The CHC composition is species‐specific and contributes to the adaptation of the animal to its ecological niche. Commonly, CHCs contribute substantially to the inward and outward barrier function of the cuticle and serve pheromonal communication. They are generally determined by gas‐chromatography, a time‐consuming method requiring detailed expertize, but it is not available in many laboratories. Here, we report on the establishment of a colorimetric method allowing semi‐quantitative determination of unsaturated CHCs in Drosophila flies. This method is based on the in vitro reaction of vanillin with double bounds in lipid molecules in an acidic solution to generate a reddish color. We found a robust correlation between gas chromatographic and vanillin‐colorimetric data on unsaturated CHCs amounts in single flies. As the role of unsaturated CHCs in the performance of insects in their environment is only partly understood, we think that this novel method would allow fast and broad analyses of this type of CHCs in insects both in the field and in laboratories and thereby contribute to a substantial improvement in the investigation of this matter.

Published: February 2024

AbstractThe arene‐arene interactions between electron‐rich and deficient aromatics have been less understood. Herein, we focus on a [60]fullerene π‐surface as an electron‐deficient aromatics. Using a 1H signal of H2O@C60 as a magnetic probe, the presence of benzene–fullerene interactions was confirmed. To investigate substituent effects on the noncovalent arene‐fullerene interactions, NMR titration experiments were carried out using an open‐[60]fullerene and a series of substituted benzenes, i. e., PhX (X=NO2, CN, Cl, OMe, H, CH3, and NH2), demonstrating a 1 : 2 stoichiometry with a positive correlation between stabilization energies upon the first association (ΔG1) and Hammet constants (σm). The destabilization of the self‐assembled structure for X=OMe with a σ‐withdrawing nature clearly showed direct through‐space substituent‐π interactions describable by the Wheeler‐Houk model while the second association was suggested to be considerably perturbed by the secondary effects.
Is “M&M® therapy” a misnomer or a concerning truth? A descriptive analysis of the use of edible reinforcers in applied behavior analytic research

Published: February 2024

AbstractReinforcement is considered an essential component of many behavioral interventions. However, caregivers may criticize the use of edible reinforcers, particularly those viewed as unhealthy. Still, as evidenced by current attitudes toward the profession, addressing the concerns and criticisms of behavior analytic consumers is paramount. Thus, the purpose of this study was to determine the extent to which edible reinforcers are used within published behavior analytic research. To this end, we analyzed research published in six major behavior analytic journals across 3 years. Results indicate that edible reinforcement was utilized in less than one third of the studies using reinforcement often in combination with other nonedible reinforcers. However, it is important to consider potential negative externalities with the use of edible reinforcement and the need for future research on the use of edible reinforcers in clinical practice and research contexts.
Does corruption sand the wheels of sustainable development? Evidence through green innovation
Authors: Majeed Muhammad Ansar , Ahsan Tanveer , Gull Ammar Ali 
Published: February 2024

AbstractThis study investigates the impact of corruption on green innovation, as corruption may impede or foster green innovation in developing economies due to their weak governance systems. We develop a dataset of Chinese non‐financial firms listed between 2007 and 2020 and apply static and dynamic regression techniques. The results indicate a highly significant negative association between corruption and green innovation. This supports the notion that corruption culture reduces corporate legitimacy concerns (institutional theory), increases managerial rent‐seeking (agency theory), and hinders green innovation, thus impeding sustainable development and supporting the “sand the wheels” hypothesis. Our analysis also reveals that corruption's negative impact on green innovation is particularly significant for firms with lower media and analyst coverage, non‐state‐owned firms, and firms in heavy‐polluting industries. These results are robust to alternate proxies of green innovation and corruption as well as econometric specifications that account for endogeneity issues and industry, region, and time‐fixed effects.
Examining #StopAsianHate discourse on Twitter using framing and thematic analyses: Focusing on motivational framing with express behaviour upon the 2021 Atlanta shootings
Authors: Lee Claire Seungeun , Jang Ahnlee 
Published: February 2024

AbstractIn separate events on March 16, 2021, an armed man walked into a spa and a massage parlour in Atlanta and shot eight people, six of whom were women of Asian descendant. Within the first week of the Atlanta shootings, more than 400,000 tweets with the hashtag #StopAsianHate emerged in response to the violence. To highlight the importance of this issue, this current study analyses 5,146 English tweets with #StopAsianHate using social movement framing. Analysis of tweets using Thematic analysis shows that proponents of the AAPI community used diagnostic framing to situate the incident in the context of systematic racial discrimination against AAPI, used prognostic framing to suggest “what” to do to resolve the problem, and used motivational framing to share action words to encourage others and to encouraging political engagements. Findings also show that other than the social movement framing, actors expressed many emotions to show their support and gave immediate reactions in response to significant events as they occurred in relation to the hate crimes. Future studies should examine whether these findings are unique to AAPI members, online social movements, or the topic of racial hate crime.

Mushroom Tyrosinase: Six Isoenzymes Catalyzing Distinct Reactions
Authors: Pretzler Matthias , Rompel Annette 
Published: February 2024

Abstract“Mushroom tyrosinase” from the common button mushroom is the most frequently used source of tyrosinase activity, both for basic and applied research. Here, the complete tyrosinase family from Agaricus bisporus var. bisporus (abPPO1‐6) was cloned from mRNA and expressed heterologously using a single protocol. All six isoenzymes accept a wide range of phenolic and catecholic substrates, but display pronounced differences in their specificity and enzymatic reaction rate. AbPPO3 ignores γ‐l‐glutaminyl‐4‐hydroxybenzene (GHB), a natural phenol present in mM concentrations in A. bisporus, while AbPPO4 processes 100 μM GHB at 4‐times the rate of the catechol l‐DOPA. All six AbPPOs are biochemically distinct enzymes fit for different roles in the fungal life cycle, which challenges the traditional concept of isoenzymes as catalyzing the same physiological reaction and varying only in secondary properties. Transferring this approach to other enzymes and organisms will greatly stimulate both the study of the in vivo function(s) of enzymes and the application of these highly efficient catalysts.
Modifications of Protein‐Bound Substrates by Trans‐Acting Enzymes in Natural Products Biosynthesis
Authors: Skala Leigh E. , Philmus Benjamin , Mahmud Taifo 
Published: February 2024

AbstractEnzymatic modifications of small molecules are a common phenomenon in natural product biosynthesis, leading to the production of diverse bioactive compounds. In polyketide biosynthesis, modifications commonly take place after the completion of the polyketide backbone assembly by the polyketide synthases and the mature products are released from the acyl‐carrier protein (ACP). However, exceptions to this rule appear to be widespread, as on‐line hydroxylation, methyl transfer, and cyclization during polyketide assembly process are common, particularly in trans‐AT PKS systems. Many of these modifications are catalyzed by specific domains within the modular PKS systems. However, several of the on‐line modifications are catalyzed by stand‐alone proteins. Those include the on‐line Baeyer‐Villiger oxidation, α‐hydroxylation, halogenation, epoxidation, and methyl esterification during polyketide assembly, dehydrogenation of ACP‐bound short fatty acids by acyl‐CoA dehydrogenase‐like enzymes, and glycosylation of ACP‐bound intermediates by discrete glycosyltransferase enzymes. This review article highlights some of these trans‐acting proteins that catalyze enzymatic modifications of ACP‐bound small molecules in natural product biosynthesis.

Published: February 2024

AbstractDue to nucleic acid's programmability, it is possible to realize DNA structures with computing functions, and thus a new generation of molecular computers is evolving to solve biological and medical problems. Pioneered by Milan Stojanovic, Boolean DNA logic gates created the foundation for the development of DNA computers. Similar to electronic computers, the field is evolving towards integrating DNA logic gates and circuits by positioning them on substrates to increase circuit density and minimize gate distance and undesired crosstalk. In this minireview, we summarize recent developments in the integration of DNA logic gates into circuits localized on DNA substrates. This approach of all‐DNA integrated circuits (DNA ICs) offers the advantages of biocompatibility, increased circuit response, increased circuit density, reduced unit concentration, facilitated circuit isolation, and facilitated cell uptake. DNA ICs can face similar challenges as their equivalent circuits operating in bulk solution (bulk circuits), and new physical challenges inherent in spatial localization. We discuss possible avenues to overcome these obstacles.

AbstractLate‐stage functionalization of indoles can be a valuable strategy for modifying different existing indolyl‐drugs and natural products to get their new analogues. In this study, we report the photoredox‐metal catalyzed decarboxylative arylation strategy of indole‐3‐acetic acids with aryl halides. Here, photoredox‐catalysis was synergistically merged with nickel‐catalysis for the synthesis of biologically important 3‐benzyl indoles with good functional group tolerance. The merit of this methodology is demonstrated by the synthesis of amino acid derived substrates 3 p, 3 v and 3 x.
An Ace in the Hole for Soil Health and Nitrogen Tracking
Authors: Sever Megan 
Published: February 2024

Abstract
Organic nitrogen constitutes the vast majority of the total nitrogen in arable soils, but since there hasn’t been a reliable method to measure it, many studies focus solely on inorganic nitrogen.
Scientists have recently confirmed that ACE protein—autoclaved‐citrate extractable protein—works well to measure the organically bound pool of nitrogen in soil.
ACE protein also provides much‐needed information about total nitrogen as well as nitrate and ammonium—inorganic nitrogen sources—and reveals how sustainable management practices can promote soil health.

Published: February 2024

AbstractFor the drawbacks of phase change materials such as poor shape stability and weak solar‐thermal conversion ability, a rotunda‐shaped carboxymethylcellulose/carbon nanotube aerogel (CA) with three‐dimensional network was constructed by freeze casting with a special mold, and then impregnated with polyethylene glycol (PEG) in this work. The PEG/CA had an enthalpy of 183.21 J/g, and a thermal conductivity of 0.324 W m−1 K−1, which was 57 % higher than the pure PEG. The ability of PEG/CA to convert solar energy to thermal energy was a positive correlation between the inclusion of CNTs and the composite material‘s thermal conductivity. Under simulated sunlight, its solar‐thermal conversion efficiency reaches 94.41 %, and after 10 min of irradiation, the surface temperature can reach 65 °C and the internal temperature can reach 44.67 °C. This rotunda‐shaped PEG/CA is promising for the efficient use of renewable solar energy due to its strong solar‐thermal conversion and thermal storage capabilities.
Securing Reversibility of UVO2+/UVIO22+ Redox Equilibrium in [emim]Tf2N‐Based Liquid Electrolytes towards Uranium Redox‐Flow Battery

AbstractWe studied electrochemical behavior of UVO2+/UVIO22+ in non‐aqueous liquid electrolytes to clarify what is required to attain its reversibility for utilizing depleted U in a redox‐flow battery. To transfer knowledge from former pyrochemical systems in high temperature molten salts, 1‐ethyl‐3‐methylimidazolium bis(trifluoromethyl)sulfonylamide ([emim]Tf2N) ionic liquid was employed here. As a result, a reversible redox reaction of the UVO2+/UVIO22+ was successfully observed on a glassy carbon working electrode under presence of Cl− in [emim]Tf2N, where [UVIO2Cl4]2−+e−=[UVO2Cl4]3− occurs after stabilization of both U oxidation states by the Cl− coordination. The observed electrochemical responses are rather sensitive to an electrode material, so that cyclic voltammograms on a Pt working electrode were actually irreversible. To improve diffusivity of solutes, viscosity (η) of [emim]Tf2N diluted with an auxiliary molecular solvent, N,N‐dimethylformamide (DMF), was examined under absence and presence of Cl−. When the mole fraction of DMF (xDMF) is 0.769, η of the mixture becomes sufficiently low to be utilized as a liquid electrolyte. Finally, we have succeeded in demonstrating a reversible redox reaction of [UVIO2Cl4]2−+e−=[UVO2Cl4]3− in the [emim]Tf2N‐DMF (50 : 50 v/v, xDMF=0.769) liquid electrolyte containing [Cl−]=0.519 M, where η=6.2 mPa ⋅ s.
