AbstractThe integration of mid‐infrared (MIR) photodetectors with built‐in encryption capabilities holds immense promise for advancing secure communications in decentralized networks and compact sensing systems. However, achieving high sensitivity, self‐powered operation, and reliable performance at room temperature within a miniaturized form factor remains a formidable challenge, largely due to constraints in MIR light absorption and the intricacies of embedding encryption at the device level. Here, a novel on‐chip metamaterial‐enhanced, 2D tantalum nickel selenide (Ta₂NiSe₅)‐based photodetector, meticulously designed with a custom‐engineered plasmonic resonance microstructure to achieve self‐powered photodetection in the nanoampere range is unveiled. Gold cross‐shaped resonators are demonstrated that generate plasmon‐induced ultrahot electrons, significantly enhancing the absorption of MIR photons with energies far below the bandgap and boosting electron thermalization in Ta₂NiSe₅, yielding a 0.1 V bias responsivity of 47 mA/W—an order of magnitude higher than previously reported values. Furthermore, the implementation of six reconfigurable optoelectronic logic computing (“AND”, “OR”, “NAND”, “NOR”, “XOR”, and “XNOR”) are illustrated via tailored optical and electrical input‐output configurations, thereby establishing a platform for real‐time infrared‐encrypted communication. This work pioneers a new direction in secure MIR communications, advancing the development of high‐performance, encryption‐capable photonic systems.

AbstractNon‐fullerene acceptors have revolutionised organic photovoltaics. However, greater fundamental understanding is needed of the crucial relationships between molecular structure and photophysical mechanisms. Herein, a combination of spectroscopic, morphology, and device characterization techniques are used to explore these relationships for a high‐performing non‐fullerene acceptor, anti‐PDFC. It focuses on transient absorption spectroscopy across multiple timescales and ultrafast time‐resolved vibrational spectroscopy to acquire the “holy grail” of simultaneous structural and dynamic information for anti‐PDFC and its blend with the well‐known conjugated polymer PM6. Most significantly, it is observed that the singlet exciton of anti‐PDFC is localised on the perylene diimide central core of the molecule, but the radical anion is primarily localised on the fluorinated indene malonitrile terminal units (which are common to many state‐of‐the‐art non‐fullerene acceptors, including the Y6 family). This electron transfer from the central core to the termini of an adjacent molecule is facilitated by a close interaction between the termini and the central core, as evidenced by single crystal diffraction data and excited state calculations. Finally, the very efficient charge extraction measured for PM6:anti‐PDFC photovoltaic devices may be correlated with this anion localization, enabling effective charge transport channels and thus enhancing device performance.
The Role of Technical Efficiency Gains on Greenhouse Gas Emissions: An Analysis of Brazilian Sugarcane Production
Authors: Soares Pedro , Spolador Humberto Francisco Silva 
Published: January 2025

ABSTRACTThis article aimed to investigate the contribution of technical efficiency gains to reducing the emission of greenhouse gases in Brazilian sugarcane production and to estimate the monetary compensation that producers should receive to reduce pollution. Using an output distance function and its duality with the revenue function, we estimated the technical efficiency of sugarcane production in Brazilian municipalities and the shadow price of reducing carbon dioxide (CO2) emissions from the production of this crop. The main result was an overall technical efficiency average of 81%, which indicates that if producers adopt better management practices, the sugarcane production could be expanded by 19% with a contraction by the same magnitude in CO2 emissions. We also estimated a mean shadow price of R$9.18 per ton of carbon dioxide, with the highest estimated values in the states of Mato Grosso do Sul, Paraná, Mato Grosso, and Bahia. However, in the state of São Paulo, the most representative national producer, the estimated shadow price is R$6.34 per ton of carbon dioxide. In this sense, public policies, especially through public financing and public technical assistance, could potentially mitigate the producers' losses in the short run since pollution decline usually requires more mechanization.

AbstractSolvent‐based electrochemical CO2 reduction (CO2R) enables the production of chemicals or fuels using CO2 from a preceding absorption process. Employing previously tested CO2 capture solvents does not ensure their suitability for either CO2R or integrated CO2 absorption‐reduction. We propose solvent selection criteria that include the CO2 solubility, kinetic constant, ionic conductivity, concentration of the bicarbonate, carbamate, and solvent cation in the CO2‐loaded solution, and sustainability indicators. They are implemented for solvent selection (a) from novel, aqueous mixtures of N‐methylcyclohexylamine (MCA) with piperazine (PZ), 2‐amino‐2‐methyl‐1‐propanol (AMP), potassium hydroxide (KOH), and potassium chloride (KCl) and (b) from aqueous monoethanolamine (MEA), AMP, KOH, MCA, and PZ solutions. Versions of a modified Kent‐Eisenberg model for strong bases, carbamate, and non‐carbamate‐forming amine solutions are developed and parameterized through experimental equilibrium measurements. CO2R experimental results are presented for solutions of KOH and MCA + KOH, as these indicate desired trade‐offs for CO2 absorption and reduction.

AbstractNi‐based alloys have excellent corrosion resistance and are widely used in the petrochemical industry. In this study, the effect of sulfuric acid on the corrosion resistance of Ni was analyzed by electrochemical tests and theoretical studies in the absence and presence of 2‐([(1E)‐(2‐hydroxyphenyl)methylene]amino)benzoic acid (H2 L). Sulfuric acid's corrosive effect, notably in fertilizer production, poses challenges for materials like nickel used in storage and transport. Discussion of nickel corrosion which is frequently used to handle sulfuric acid is given in this paper. The corrosion behavior of nickel (Ni) metal and the inhibitory effect of 2‐([(1E)‐(2‐hydroxyphenyl)methylene]amino)benzoic acid (H2L) were investigated using a combination of electrochemical and computational approaches. In this study, 0.5 M sulfuric acid served as the corrosive medium. The inhibitory effect of H2L was evaluated using Tafel plots and electrochemical impedance spectroscopy. Results show a gradual decrease in the corrosion current density (Icorr.) over time, accompanied by an increase in inhibition efficiency, attributed to rising additive concentrations. The maximum inhibition efficiency (η=97.8 %) was achieved at 1×10−5 M additive concentration and 25 °C. The additive predominantly affects the anodic reaction compared to the cathodic reaction and reduces NiO formation on electrode surfaces. Increasing solution temperature enhances inhibition efficiency, indicating chemisorption following the Langmuir model, supported by electrochemical impedance spectroscopy. Scanning electron microscopy (SEM) analysis confirms that H2 L inclusion significantly enhances nickel corrosion resistance. Charge‐discharge processes of Ni were studied in 0.5 M H2SO4 containing various dosages of the additive at applied distinct current densities. It is interesting to note that both discharging time and specific capacitance rises with raising the applied current density at each dosage of additive in 0.5 M H2SO4. The most enhancements were obtained at presence of 1×10−5 M of the additive, as corrosion resistance and specific capacitance (0.391 mAh at 90 mA cm−2). Also, improved power and energy features are obtained in the presence of this concentration of the additive. Theoretical Density Functional Theory (DFT) studies reveal that H2L possesses a low ΔEgap, facilitating chemical adsorption during the inhibition process, underlining the innovative nature of this corrosion inhibition strategy. Furthermore, the H2L−Ni interaction was effectively simulated using the DFT/B3LYP/6‐311+G**, providing valuable insights into the compound's corrosion inhibition capabilities.
Longitudinal monitoring of class‐switched memory‐B cell proportions identifies plausible germinal center failure in patients with suspected immune disorders

AbstractA reduced proportion of peripheral class‐switched memory B cells (CSM‐B cells) is presumed to indicate ineffective germinal activity. The extent that this finding corresponds to a plausible germinal center failure pathophysiology in patients not diagnosed with CVID or hyper IgM syndrome is not known. We asked if patients with low CSM‐B cells are more likely to demonstrate failure to produce serum IgA and IgG than counterparts with nonreduced class‐switched memory B cell levels, regardless of diagnosis. Patients with low CSM‐B cell levels regardless of diagnosis were retrospectively compared with their counterparts without CSM‐B cell reductions for demographics and serum immunoglobulin levels. Patients were further divided based on whether CSM‐B cell levels remained low over time or fluctuated, and these groups were compared for serum immunoglobulin levels and diagnoses. Of 305 patients, those with CSM‐B cell (n = 50) reductions were more likely to have low serum IgA and IgG than those without reductions. Of the 78 patients in whom CSM‐B cells were measured repeatedly over time, 21 patients had low CSM‐B cell levels, but this finding was persistent in only 10. Patients with persistent CSM‐B cell reductions universally had severe serum IgA and IgG deficiencies and patients with transient CSM‐B cell reduction often did not. These two groups contained divergent diagnoses and likely represent separate pathophysiologic groups. Quantifying CSM‐B cells as a percentage of CD27+ B cells repeatedly over time is a robust approach to identifying patients with a plausible germinal center failure endotype.

AbstractAimsA cardiovascular magnetic resonance (CMR) approach to non‐invasively estimate left ventricular (LV) filling pressure was recently developed and shown to correlate with invasively measured pulmonary capillary wedge pressure (PCWP). We examined the association between CMR‐estimated PCWP (CMR‐PCWP) and other imaging and biomarker measures of congestion, and the effect of empagliflozin on these, in the SUGAR‐DM‐HF trial (NCT03485092).Methods and resultsSUGAR‐DM‐HF enrolled 105 patients with heart failure with reduced ejection fraction (HFrEF) and pre‐diabetes or type 2 diabetes who were randomly assigned to empagliflozin 10 mg or placebo once daily for 36 weeks. Transthoracic echocardiography (TTE) was performed at screening and physical examination, lung ultrasound (LUS), CMR, and blood sample collection at baseline and 36 weeks. The mean age of participants was 69 years, mean LV ejection fraction was 33%, and mean CMR‐PCWP was 15.1 mmHg (standard deviation 2.5 mmHg). CMR‐PCWP correlated with log N‐terminal pro‐B‐type natriuretic peptide (Pearson's r = 0.31, p = 0.0012), total number of B‐lines on LUS (Spearman's rho = 0.34, p < 0.001), TTE average E/e' (r = 0.22, p = 0.03) and CMR ventricular volumes (LV end‐systolic volume: r = 0.51, p < 0.001; right ventricular end‐systolic volume: r = 0.55, p < 0.001). Mean CMR‐PCWP decreased from baseline to 36 weeks by −0.37 (95% confidence interval −0.78 to 0.05) mmHg and −0.17 (−0.69 to 0.36) mmHg in the empagliflozin and placebo groups, respectively; placebo‐corrected difference −0.43 mmHg (−1.09 to 0.23, p = 0.20).ConclusionCardiovascular magnetic resonance‐estimated PCWP correlates with clinical and ultrasound markers of congestion in HFrEF. CMR not only enables assessment of cardiac structure and function but also provides a non‐invasive assessment of LV filling pressure.

ABSTRACTOptimizing the continuous phase hydrostatic pressure and the temperature differential between working phases is essential in designing direct contact heat exchangers. This study presents an experimental investigation into the influences of the continuous phase active height, corresponding to hydrostatic pressure, and the temperature differential between the working liquids on the evaporation dynamics of a single volatile drop in an immiscible fluid. The experiments were carried out within a Perspex rectangular column with 100 × 100 × 600 mm dimensions. N‐pentane (C5H12) at its saturation temperature was utilized as the dispersed phase, while the continuous phase comprised warm water at three distinct temperatures, resulting in three distinct Jacobian numbers (Ja = 18, 30, and 45). Three active water heights (300, 400, and 500 mm) were investigated to assess the impact of hydrostatic pressure on droplet evaporation. A high‐speed camera was employed to capture the droplet's evaporation along the continuous phase's active height, and the images were analyzed using FASTCAM (PFV‐4) and AutoCAD (3D) software. The key parameters measured included droplet volume (or diameter), open angle (β), vaporization ratio (x), and the total time required for complete droplet evaporation. The experimental findings indicate that the droplet's diameter, open‐angle (β), and vaporization ratio (x) increased over time and were notably influenced by the continuous phase hydrostatic pressure. Additionally, the growth rate of the two‐phase drop‐bubble accelerated, and the total time for complete evaporation decreased as the active height of the continuous phase was reduced. An empirical correlation for the two‐phase drop‐bubble size in terms of Ja, H, Ho, and was developed and compared successfully with the experimental data with a maximum error of about

ABSTRACTObjectivesA major characteristic of health anxiety is the tendency to attribute benign bodily sensations to serious illnesses. This has been supported by empirical research in non‐clinical samples, and samples of individuals diagnosed with Hypochondriasis. However, no study to date has explored symptom attribution styles of individuals with the DSM‐5 diagnosis of Illness Anxiety Disorder.MethodsSixty‐one participants, including a clinical Illness Anxiety Disorder (n = 35) and healthy control (n = 26) sample, completed self‐report measures of health anxiety and an Attribution Task, whereby they were presented with eight common bodily sensations and asked to generate possible explanations for them.ResultsResults showed that relative to healthy controls, participants with Illness Anxiety Disorder overall were more likely to make more serious, ‘catastrophic’ somatic attributions to symptoms, and less likely to generate non‐threatening normalising explanations. These results also extended to their initial attributions, conceptualised as the ‘jumping to conclusions’ bias, and as an exploratory index of flexibility, they were also found to make less attributions overall compared to healthy controls.ConclusionsFindings provide support for the cognitive behavioural theory of health anxiety, and highlight the importance of assessing and addressing symptom attributions with clients with illness anxiety disorder.
Room‐Temperature and Ultrafast Synthesis of Sub‐4 nm Yb3+/Nd3+ Ions‐Doped CaMoO4 Nanocrystals with Near‐Infrared Photoluminescence Quantum Yield of 40%

Published: January 2025

AbstractRare‐earth doped metal oxide nanocrystals with high visible luminescence have been widely used in lighting and display applications owing to their low toxicity, and excellent thermal and chemical stability. However, the room‐temperature preparation of near‐infrared (NIR) luminescent rare‐earth doped metal oxide nanocrystals remains a challenge. Herein, sub‐4 nm Yb3+/Nd3+‐doped CaMoO4 nanoparticles are prepared by a facile room‐temperature ligand‐assisted coprecipitation method, which can be completed within 1 min under ambient conditions. Short‐chain butyric acid and butylamine as binary ligands play a crucial role in the synthesis of NIR luminescent nanoparticles. The as‐prepared nanocrystals can be well dispersed in organic solvents such as chloroform since they are capped with butyric acid and butylamine. The energy transfers from ions to Yb3+ and Nd3+ ions are systematically investigated in CaMoO4:Yb3+ and CaMoO4:Nd3+ nanoparticles, respectively. More importantly, this ultrafast and room‐temperature synthesis strategy is particularly suitable for the large‐scale preparation of Yb3+/Nd3+‐doped CaMoO4 nanoparticles (≈23 g) with NIR emission, which provides new ideas and possibilities for the commercial production of extremely small and NIR‐emitting nanophosphors.

ABSTRACTCharacterisation of eco‐friendly biodegradable lubricant is a significant investigation in the replacement of the toxic mineral/synthetic oil that creates a negative impact on health. In this study, the nanoparticle titanium dioxide (TiO2) was synthesised by the coprecipitate method and dispersed in the palm oil blended with Moringa oleifera seed oil (enriched palm oil‐EPO) to prepare a biodegradable lubricant. Structural and compositional analysis of TiO2 nanoparticles was carried out using scanning electron microscope (SEM), X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy analysis (FTIR). The biodegradable lubricant nature of TiO2 dispersed at different volume fractions in EPO was investigated by varying viscosity and density with temperature (30°C–60°C), and the Brownian motion of the particle in the oil was studied through the diffusion constant, diffusion time and Brownian velocity. The biodegradable lubricant nature of TiO2 has been analysed using machine learning (ML) techniques that categorise the lubricant nature of the blended oil.

AbstractObjectiveTo validate the use of neural radiance fields (NeRF), a state‐of‐the‐art computer vision technique, for rapid, high‐fidelity 3‐dimensional (3D) reconstruction in endoscopic sinus surgery (ESS).Study DesignAn experimental cadaveric pilot study.SettingAcademic medical center.MethodsComplete bilateral endoscopic sinus surgery was performed on 3 cadaveric specimens, followed by postsurgical nasal endoscopy using a 0° rigid endoscope. NeRF was utilized to generate 3D reconstructions from the monocular endoscopic video feed. Reconstructions were calibrated, scaled, and then co‐registered to postoperative computed tomography (CT) image sets to assess accuracy. Reconstruction error was determined by comparing ethmoid sinus measurements on NeRF reconstructions and CT image sets.ResultsNeRF‐based 3D scene reconstructions were successfully generated and co‐registered to corresponding CT images for 5 out of 6 cadaveric nasal cavity sides. The mean reconstruction errors and standard error of the mean (SEM) for ethmoid length and height were 0.17 (SEM 0.59) and 0.70 (SEM 0.44) mm, respectively.ConclusionNeRF demonstrates significant potential for dynamic, high‐fidelity 3D surgical field reconstruction in ESS, offering submillimeter accuracy comparable to postoperative CT data in cadaveric specimens. This innovative approach may ultimately augment dynamic real‐time intraoperative navigation through co‐registration of the 3D reconstruction with preoperative imaging to potentially reduce the risk of injury to critical structures, optimize surgical completeness and, thereby, improve surgical outcomes. Further refinement and validation in live surgical settings are necessary to fully realize its clinical utility.
