Published: July 2024

AbstractLarge‐scale particle manipulation with single‐particle precision and further flexible patterning into functional structures is of huge potentials in many fields including bio‐optoelectronic sensing, colloidal lithography, and wearable devices. However, it is very challenging for the precision manipulation and flexible patterning of particles on complicated curved and functional substrates. In this work, opto‐thermal‐tension (OTT) mediated precision large‐scale particle manipulation and flexible patterning based on soap film are reported. Flexible manipulation and subsequent patterning of particles with single‐particle resolution is realized by optothermal regulated surface tension on soap films. Reconfigurable patterning of particle structures with different shapes as well as large‐scale ordered structures (up to 2000 particles) with particle sizes spanning two orders of magnitude (0.5–20 µm) is realized using this OTT mediation method. Importantly, due to the high flexibility of soap films, the patterned large‐scale particle structures can be non‐destructively transferred to curved and rough substrates, including rough iron pipe surface, leaf and skin surface. This OTT mediated method provides a new method for precision large‐scale particle manipulation and flexible patterning with high versatility on complicated functional substrates, with great potentials for optoelectronic and biophotonic sensing and wearable device design on different curved and rough functional substrates.

AbstractSodium‐ion batteries (SIBs) have attracted a lot of attention owing to their low cost, as well as similar working mechanism and manufacturing technique to lithium‐ion batteries. However, the practical application of SIBs is severely hindered by limited electrode materials. Disordered carbons are reported to be promising as anode materials for SIBs. Here, for the first time, calcium lignosulfonate (LSCa), one papermaking waste, is explored as a novel low‐cost precursor for carbon materials of SIBs. The optimized LSCa‐derived carbon delivers a high reversible capacity of 317 mA h g−1 at 30 mA g−1 with ~60% plateau capacity, and it retains a capacity of 170 mA h g−1 even at 3000 mA g−1. These achievements are ascribed to the larger d002 values, smaller defects, and more closed pores, compared with the original sample from the direct carbonization of LSCa.

Published: July 2024

AbstractHerein, we have reported an effective protocol for the regioselective transfer hydrogenation (TH) of epoxides by utilizing a phosphine‐free bis‐NHC−Mn(I) complex and ammonia borane. By employing this strategy, aromatic epoxides were selectively converted to primary alcohols whereas secondary alcohols were obtained exclusively from aliphatic epoxides. The protocol was further extended for the TH of azoarenes and nitroarenes to hydrazoarenes and anilines respectively. Notably, a library of substrates with different functional groups were screened which resulted in the corresponding transfer hydrogenated product in good to excellent yields. A series of mechanistic investigations were carried out to understand the catalytic process.
Formate Dehydrogenase: Recent Developments for NADH and NADPH Recycling in Biocatalysis
Authors: Maier Artur , Mguni Lindelo M. , Ngo Anna C. R. , Tischler Dirk 
Published: July 2024

AbstractFormate dehydrogenases (FDHs) catalyze the oxidation of formate to CO2 while reducing NAD(P)+ to NAD(P)H and are classified into two main classes: metal‐dependent (Mo‐ or W‐containing) and metal‐independent FDHs. The latter are oxygen‐tolerant and relevant as a cofactor regeneration system for various bioprocesses and gained more and more attention due to their ability to catalyze the reverse CO2 reduction. This review gives an overview of metal‐independent FDHs, the recent advances made in this field, and their relevance for future applications in biocatalysis. This includes the exploitation of novel FDHs which have altered co‐substrate specificity as well as enzyme engineering approaches to improve process stability and general performance.

Published: July 2024

AbstractThis study reports the photoelectrocatalytic (PEC) activity of a n–n heterojunction comprising MoS2 and NiSe2. The synthesis of the composite was achieved through a facile solvothermal method, yielding an exfoliated MoS2 layered sheet loaded with NiSe2 nanoparticles. Under visible light radiation and an external electric field, the obtained composite NiSe2/MoS2 exhibited enhanced catalytic activity for ciprofloxacin (CIP) degradation. The NiSe2/MoS2 heterojunction achieved about 78 % degradation efficiency with a first‐order kinetic rate of 0.0111 min−1, compared to 38 % efficiency and a first‐order kinetic rate of 0.0044 min−1 observed for MoS2. The NiSe2/MoS2 heterojunction was more advantageous due to the synergy of charge carrier induction by visible light radiation and improved charge carrier separation induced by the external electric field. The formation of n–n heterojunction at the interface of the two materials resulted in charge redistribution in the materials, with a simultaneous realignment of the band structure to achieve Fermi energy equilibration. The primary reactive species responsible for CIP degradation was identified as the photo‐induced h+. Furthermore, the catalyst exhibited high stability and reusability, with no significant reduction in activity observed after five experimental cycles. This study reveals the potential of exploring the synergy between the photocatalytic and electrocatalytic processes in removing harmful pharmaceutical compounds from water.

Published: July 2024

AbstractHere, we report the first cytology findings of the newly characterized entity, palisading adenocarcinoma of the salivary gland, diagnosed in the sublingual gland of a 61‐year‐old female. The liquid‐based cytology showed a moderately cellular aspirate containing three‐dimensional clusters and trabeculae of tumor cells of various sizes. The cells had dark ovoid nuclei, finely granular chromatin, inconspicuous to punctate nucleoli, and ample cyanophilic cytoplasm with indistinct cell borders. In conventional smears, the cells displayed frequent crush artifacts and anisonucleosis resembling endocrine‐type atypia. The background was clean, devoid of secretions, and contained singly dispersed tumor cells with stripped nuclei. Interestingly, concentrically laminated globules of extracellular matrix surrounded by the tumor cells were identified. Mitotic figures and tumor necrotic debris were absent. The cytologic findings correlated with the histologic findings of the excision specimen. The cytologic differential diagnosis and tumor grading of palisading adenocarcinoma were briefly discussed.

AbstractHeavy metals, a major source of pollution in the environment, pose a substantial threat due to their non‐biodegradability and ability to accumulate in living organisms, causing health problems. Recently, researchers have been searching for cost‐effective and safe ways to remove heavy metals from polluted waterways using agricultural waste substitutes. The present study focused on the low‐cost treatments for the reduction of chromium Cr+6 metal from the effluent, wherein it has been found that chemically and bacterially treated agro‐waste had increased heavy metal ion adsorption capabilities. A sequential optimization of the process parameters was attempted using Plackett–Burman design (PBD) and central composite design of response surface methodology (CCD‐RSM) for the maximum reduction of the chromium metal from the effluent. A total of eight parameters were screened out using a 12‐run PBD experiment. Out of the eight parameters, time, HCl, NaOH, and bacterial treatments were found to be significantly affecting the maximum reduction of Cr+6 from the effluent. To investigate the interactions' effects of the chosen parameters, they were evaluated using CCD‐RSM. Maximum 74% Cr+6 reduction was achieved under the optimum treatment to rice husk of HCl 4.52 N, NaOH 3.53 N, bacterial suspension 7.41%, and with an interaction time 14.32 min using 30 run CCD‐RSM experiment. A scanning electron microscope was used to confirm the effects of selected variables on the agro‐waste for the Cr+6 reductions, as well as a Fourier transform infrared spectrometer.

Evaluation of a latency‐based competing stimulus assessment
Authors: Imler Madison H. , Weyman Jennifer R. 
Published: July 2024

AbstractA competing stimulus assessment is used to identify stimuli that are associated with a low level of challenging behavior and a high level of engagement. These stimuli are often used as a treatment component for challenging behavior that is maintained by automatic reinforcement. One limitation of implementing competing stimulus assessments is that they may be time consuming. The purpose of the current study was to evaluate the efficacy and efficiency of a latency‐based competing stimulus assessment. During the asssessment, a therapist presented potential competing stimuli to the participants and contingent on the first occurrence of challenging behavior, the trial was terminated. The results of a brief treatment evaluation indicated that stimuli that were associated with the longest latency to challenging behavior were more effective in competing with challenging behavior relative to stimuli that were associated with shorter latencies. However, procedural modifications were necessary for one participant. The use of latency‐based measures improved the efficiency of conducting a competing stimulus assessment.
Direct and indirect effects of and preferences for feedback during the Good Behavior Game in elementary classes
Authors: Chotto Jensen , Linton Elizabeth , Donaldson Jeanne M. 
Published: July 2024

AbstractThe Good Behavior Game (GBG) is an effective procedure for reducing disruptive classroom behavior. Students in three fifth‐grade classes selected the rules of the GBG and then experienced the GBG with different forms of feedback for rule violations (vocal and visual, vocal only, visual only, no feedback). Following an initial baseline, the four feedback versions of the GBG and a baseline condition were alternated across sessions in a multielement design. All versions of the GBG substantially reduced disruptive behavior below baseline levels. Additionally, in one of the three classes losing the GBG produced an increase in negative peer interactions immediately following the GBG. Following the multielement comparison, we implemented a group‐arrangement concurrent‐chains preference assessment in which students selected one of the conditions to experience each day. The most selected condition across all classes was the GBG condition, which included both vocal and visual feedback.

Published: July 2024

AbstractBACKGROUNDTruffle cultivation is evolving rapidly and new agronomic practices such as ‘truffle nests’ (localized peat amendments of the orchard soil) are being developed. Truffle nests improve the shape of truffles and their depth in the soil and reduce the occurrence of insect damage but have also raised concerns about their impact on the ripeness and maturity of the harvested truffles. In this study, the effect of the nests on the volatile organic compounds profile and the aromatic profile of black truffles was evaluated, as well as the existence of perceptible sensorial differences in truffles. For this, truffles growing in nests were compared with truffles growing in the bulk soil of the same host tree.RESULTSGas chromatography showed that nest truffles had a less complex volatile organic compound profile than bulk‐soil truffles. Olfactometry indicated that nest truffles were associated with higher modified frequency values of odorants corresponding to sulfur‐containing compounds. Despite this, sensory evaluation with consumers could not clearly show that nest truffles can be distinguished sensorially from bulk‐soil truffles.CONCLUSIONThe results prove that soil conditions can influence the aromatic profile of truffles and thus suggest the possibility of managing truffle aroma using agronomic practices. © 2024 The Author(s).

ABSTRACTContextMeditation and related relaxation techniques are good means of alleviating stress and maintaining good health. Osho dynamic meditation decreases several psychopathological variables such as anxious‐depressive syndrome, aggressive behaviors, and depression which is practiced in Nepal and all over the world. Various studies have shown alteration in different hormone levels due to meditation by strengthening adaptive mechanisms.AimThe aim of this study was to evaluate the effect of Osho meditation on serum hormonal levels in pre‐ and postmeditation participants.MethodsA pre–post study was conducted among 70 healthy volunteers (42 male and 28 female) where various types of Osho dynamic meditation techniques were incorporated together to understand their combined effects on serum hormone levels in participants attending the 7 days meditation camp. Serum hormones such as cortisol, estrogen, progesterone, free triiodothyronine (fT3), free thyroxine (fT4), thyroid‐stimulating hormone (TSH), testosterone, and growth hormone were measured by chemiluminescence immunoassay.ResultsOut of 70 participants, 68 participants (97%) had subjective opinion of Osho dynamic meditation being effective in alleviating stress, depression, and anger. Also, there was a significant decline in body weight and body mass index in both male and female populations after a strict vegetarian diet and meditation. Likewise, a significant rise in the level of estrogen (p < 0.001), progesterone (p < 0.001), growth hormone (p < 0.001), testosterone (p = 0.002), and fT3 (p = 0.049) in postmeditation male participants indicates the importance of Osho dynamic meditation on elevating sex hormones such as estrogen, progesterone, testosterone as well as fT3, and growth hormones among Osho meditation practicing participants.ConclusionOur findings suggest significant changes in the hormonal levels and improvement in stress and depression in participants undergoing Osho meditation.

Published: July 2024

AbstractHydrogel‐based stress‐strain sensors have attracted immense attention recently for developing wearable electronic devices and health‐monitoring systems owing to their intrinsic soft characteristics and flexible nature. Developing hydrogel that has high conductivity, better mechanical performance, and elasticity is necessary for better analysis or getting accurate measurement data. Hence, this study focuses on the development of novel conductive hydrogels with enhanced mechanical, swelling, and sensing properties targeting the advancement of stress‐strain sensitive hydrogel sensors. Polyvinyl alcohol (PVA) and citric acid (CA) have been used to prepare esterified PVA/CA hydrogels while using a simple one‐pot method followed by doping with a conductive polymer (polyaniline, PANI). The resultant PVA/CA/PANI hydrogel displayed a high water uptake capacity of ∼4200%, a high mechanical strain of 700%, high puncture resistance, large durability, and a fast response time when applied as soft human‐motion sensors in real‐time measurement of large‐scale and subtle human physiological stress activities (i.e., joint motions in the forefinger, elbow, wrist, and neck). The high strain sensitivity and ultrahigh stretchability of hydrogel sensors allow them to detect small mechanical changes caused by human movement showing their great potential for hydrogel‐based sensor device fabrication.

Published: July 2024

AbstractWe present machine learning (ML) methods for automatically selecting a “best” performing fast algorithm for the capacitated vehicle routing problem (CVRP) with unit demands. Algorithm selection is to automatically choose among a portfolio of algorithms the one that is predicted to work best for a given problem instance, and algorithm configuration is to automatically select algorithm's parameters that are predicted to work best for a given problem instance. We present a framework incorporating both algorithm selection and configuration for a portfolio that includes the automatically configured “Sweep Algorithm,” the first generated feasible solution of the hybrid genetic search algorithm, and the Clarke and Wright algorithm. The automatically selected algorithm is shown here to deliver high‐quality feasible solutions within very small running times making it highly suitable for real‐time applications and for generating initial feasible solutions for global optimization methods for CVRP. These results bode well to the effectiveness of utilizing ML for improving combinatorial optimization methods.

AbstractIn this study five different complexes of Cu(II) were synthesized for the purpose of environmentally notorious mercury sensing and preliminary biological screening. Pyridine‐2,6‐dicarboxylic acid (also known as dipicolinic acid, and abbreviated as H2DPA), 3‐phenyl pyrazole (3‐ppz), 4‐iodo‐1H‐pyrazole (4‐ipz), 4‐nitropyrazole (4‐npz), 4‐bromopyrazole (4‐bpz), and 4‐chloropyrazole (4‐cpz) were chosen as potential ligands. The synthesized complexes labelled as 1–5, namely [Cu(DPA)(3‐ppz)], [Cu(DPA)(4‐ipz)], [Cu(DPA)(4‐npz)], [Cu(DPA)(4‐bpz)], [Cu(DPA)(4‐cpz)], were proposed based on spectroscopic data (FTIR, TGA, and UV‐visible spectroscopy). These complexes feature C=O functionalities that are not involved in coordination and may be used for further applications. The isolated complexes were utilized for detecting Hg(II) ions in water samples. Various concentrations of Hg(II) ions were prepared for detection purposes, and changes in absorption concerning complexes 1–5 were determined using UV‐Visible spectroscopy. It was found that complexes 3 and 4 exhibit efficient sensing abilities towards Hg(II) ions. The antibacterial activities of complexes 1–5 were assessed against S. typhi and E. coli. The complexes 1 and 3 displayed good antibacterial activities against S. typhi (13.67, and 13.56 mm, respectively) while complexes 1, 2 and 4 were found to be efficient against E. coli (11.6, 12.66, 11.31 mm, respectively). The absorption maxima of 2,2‐diphenyl‐1‐picryhydrazyl (DPPH) at 517 nm, considerably shifted upon addition of complexes 1–5. The results reveal that the complexes possess potential free radical scavenging abilities.

AbstractPervaporation (PV) is a promising membrane‐based technology for dehydrating alcohols and separation of close‐boiling liquids. Poly(styrene sulfonic acid‐co‐maleic acid) (PSSAMA) crosslinked sodium alginate (NaAlg) membrane was developed, and was then modified by varying the mass% of sulfonated graphite oxide (SGO). Physicochemical properties of the resulting membranes were assessed using FTIR, WXRD, TGA, DSC, and SEM. The pervaporation study was carried out to assess membrane performance in dehydrating isopropanol. The membrane with 16 mass% of SGO exhibited the highest separation factor of 6025 and flux of 14.66 × 10−2 kg m−2 h−1 at 30°C for 10 mass% of water in the feed and were able to break the water–isopropanol azeotropic point. The activation energy for water permeation (Epw) was lower than that of isopropanol permeation (EIPA), indicating the high separation ability. Activation energies for total permeation (EP) and total diffusion (ED) ranged from 12.42 to 49.13 and 12.99 to 54.42 kJ mol−1, respectively. Negative enthalpy values (ΔHs) suggested Langmuir's sorption predominance for all membranes.Highlights
