Time-dependent effect of intense capsule-coffee and bleaching on the color of resin-infiltrated enamel white spot lesions: anin vitrostudy
Authors: Yeslam Hanin E. , AlZahrani Saeed J. 
Published: October 2022

Background and ObjectivesWhite spot lesions (WSLs) are a common problem that can be conservatively managed by resin infiltration. Consumption of dark beverages such as coffee causes staining of dental hard tissues, which can deteriorate the esthetic qualities of treated WSLs. The aims of this study were to investigate the effect of dark coffee heavy consumption on ICON®resin infiltrated WSLs and the influence of bleaching on them after staining.MethodsTwenty surfaces from sound human extracted third molars were used in the study. Two square-shaped buccal and lingual window areas had artificially created WSLs (received buccal resin infiltration afterward). Using VITA Easyshade, the baseline ΔEwas recorded. Espresso coffee was used to immerse all surfaces for 8 days. The color coordinates according to CIE LAB were recorded for all surfaces at 2, 4, 6, and 8 days of immersion, and ΔEwas calculated at each timepoint. After 8 days, in-office bleaching was applied to all surfaces according to the manufacturer’s instructions and the color. Coordinates and ΔEwere recorded. For statistical analysis, an independent samplet-test was used to compare each group. A general linear mixed model (GLMM) repeated measure ANOVA was applied for statistical analysis of L*and changes due to staining over time.ResultsAnalysis of time as a main effect on the L values of surfaces was statistically highly significant (p< 0.01). The interaction of time with surfaces under investigation and type of surface (test vs. control) as a main effect were non-significant (p= 0.47 andp= 0.35, respectively). Bleaching showed a significant difference in color lightness in both test and control surfaces compared to the meanLvalue at 8 days of staining (p< 0.01).ConclusionCapsule-coffee consumption gradually influences the esthetic of resin infiltration on treated teeth. However, bleaching materials might restore an esthetic shade.

AbstractRu‐porphyrins act as convenient pedestals for the assembly of N‐heterocyclic carbenes (NHCs) on solid surfaces. Upon deposition of a simple NHC ligand on a close packed Ru‐porphyrin monolayer, an extraordinary phenomenon can be observed: Ru‐porphyrin molecules are transferred from the silver surface to the next molecular layer. We have investigated the structural features and dynamics of this portering process and analysed the associated binding strengths and work function changes. A rearrangement of the molecular layer is induced by the NHC uptake: the NHC selective binding to the Ru causes the ejection of whole porphyrin molecules from the molecular layer on silver to the layer on top. This reorganisation can be reversed by thermally induced desorption of the NHC ligand. We anticipate that the understanding of such mass transport processes will have crucial implications for the functionalisation of surfaces with carbenes.
Imaging Photoelectron Circular Dichroism in the Detachment of Mass‐Selected Chiral Anions
Authors: Triptow Jenny , Fielicke André , Meijer Gerard , Green Mallory 
Published: October 2022

AbstractPhotoelectron Circular Dichroism (PECD) is a forward‐backward asymmetry in the photoemission from a non‐racemic sample induced by circularly polarized light. PECD spectroscopy has potential analytical advantages for chiral discrimination over other chiroptical methods due to its increased sensitivity to the chiral potential of the molecule. The use of anions for PECD spectroscopy allows for mass‐selectivity and provides a path to simple experimental schemes that employ table‐top light sources. Evidence of PECD for anions is limited, and insight into the forces that govern PECD electron dynamics in photodetachment is absent. Here, we demonstrate a PECD effect in the photodetachment of mass‐selected deprotonated 1‐indanol anions. By utilizing velocity map imaging photoelectron spectroscopy with a tunable light source, we determine the energy‐resolved PECD over a wide range of photon energies. The observed PECD reaches up to 11 %, similar to what has been measured for neutral species.
Multi‐factor influence on the properties of polymer fiber‐based artificial muscles

Published: October 2022

AbstractThermosensitive polymer artificial muscle fiber filaments made of two polymers, cyclic olefin copolymer elastomer (COCe) and polyethylene (PE), have the ability to sense changes generated by the external environment temperature. To optimize the thermosensitive polymer performance, this work investigates the effects of heating temperature, tensile load, strain rate, and mix proportion applied to COCe‐PE polymers on mechanical properties of the resulting fiber‐based muscle. The fiber filament deformation, stress distribution, and penetration characteristics are compared with multifactor coupling parameters utilizing a computational fluid dynamics simulation model. The simulation results show that although increasing the heating temperature has a small effect on the deformation of the fiber filaments, the interpenetration between the materials is better improved with the increase of temperature. Increasing the tensile load and strain rate can effectively increase the fiber filament deformation and improve the interpenetration between materials. The mix proportion of the two materials has a large effect on the plasticity and brittleness of the materials, and the different mix proportion also have a profound effect on the interpenetration. This study could provide some guidelines for the manufacture of artificial muscle fiber filament.

AbstractThis paper prepared potassium oleate/silica/natural rubber composites by atomization spray drying technology. This study compared the effects of the environmental protection accelerator potassium oleate and amine accelerator 1,3‐diphenylguanidine on the Payne effect, silane reaction index, vulcanization performance, mechanical properties, static and dynamic mechanical properties, and aging properties of silica/natural rubber. The results show that potassium oleate can promote the silane reaction and increase the silane reaction's efficiency. When potassium oleate formed the silica coating, the carboxyl group of potassium oleate and the hydroxyl group of silica were bonded to form a covalent bond, which reduced the polarity of silica and promoted the dispersion effect of silica in the rubber matrix and enhanced the compatibility with rubber. Compared with the original formulation, after adding 3 phr of potassium oleate, the fracture elongation of vulcanized rubber was increased by 17.2%, tensile product increased by 57.3% and rolling resistance decreased by 54.6%. After adding 3 phr of 1,3‐diphenylguanidine, the fracture elongation of vulcanized rubber was increased by 1.1%, tensile product increased by 51.1% and rolling resistance decreased by 48.6%. In contrast, the anti‐aging performance of the rubber composites with potassium oleate was better than that of 1,3‐diphenylguanidine. This study opens up a new way to apply a new green rubber accelerator and prepare high‐performance rubber composites.

AbstractIn the wake of increasingly serious challenges in oilfield production and energy utilization, oil and gas reservoirs with ultra‐low permeability have gained tremendous importance for global energy supply. In such reservoirs, hydraulic fracturing is an important stimulation measure. Here, to develop a high‐performance fracturing fluid, a novel type of water‐based thickener named FPM‐2 was exploited based on low‐molecular weight alcohol and hydrophobically associating polymers, labeled as AAOS, and synthesized using acrylamide, acryloyl acid, octadecyl dimethyl allyl ammonium chloride, and octadecyl methacrylate. Dissolution rate and scanning electron microscope results showed the system to be a fast‐soluble thickener with a spatially cross‐linked network structure. The viscosity of 0.8 wt% FPM‐2 reached up to 216 mPa·s. Investigation of the rheological behavior showed that the thickener, 1.4 wt% FPM‐2, could withstand a temperature up to 180°C after being sheared for 80 min at 170 s−1, and its viscosity was up to 53 mPa·s. The 0.6 wt% FPM‐2 sample also displayed excellent shear recovery properties and high viscoelasticity. The most fascinating aspect of FPM‐2 was that its unique formula imparted the thickener with characteristics such as enhanced self‐association, waterproof locking, and prevention of wax formation. In this research, the recovery value of core permeability exceeded 80%, and wax was precipitated as small‐sized particles that prevented pipeline blockage. Therefore, the use of this multi‐effect cleansing thickener should set the trend for the development of oil and gas resources.
Microplitis bicoloratus parasitism promotes cyclophilin D‐p53 interaction to induce apoptosis of hemocytes in Spodoptera litura

AbstractMicroplitis bicoloratus parasitism can induce apoptosis of hemocytes in the M. bicolortus host, Spodoptera litura. However, it is unclear how M. bicolortus parasitism regulates host signaling pathways to induce apoptosis. Expression of cyclophilin D (CypD) and p53 was significantly upregulated in S. litura hemocytes at 6 days postparasitization. In the parasitized hemocytes, there was mitochondrial membrane potential (△Ψm) loss, cytochrome c (Cyt C) release from mitochondria, and caspase‐3 activation. These occurred while hemocytes were undergoing upregulation of CypD and p53. Parasitism also promoted the interaction between CypD and p53. CypD silencing could rescue the apoptotic phenotypes induced by parasitism, but had no effect on apoptosis in unparasitized S. litura. These findings suggest that the CypD‐p53 pathway may be an important component of the parasitism‐induced immunosuppressive response and establish a basis for further studies of parasitoid/host interactions.

Published: October 2022

AbstractTemperature is an important biophysical parameter that is closely related with the metabolic activity in living cells. Therefore, the detection of intracellular temperature changes is crucial for exploring temperature‐related biological processes. Fluorescence probe is an ideal tool for observing temperature changes in cells, which has many advantages, such as high sensitivity, good selectivity, and noninvasive, and thus aroused the great interest of researchers. In this paper, we summarize the recent progress of organic small molecule temperature‐sensitive fluorescence probes in recent years was reviewed. Particularly, we describe the common response mode to the temperature and the practical applications of the probe in living cells and even animal models. Moreover, an outlook regarding temperature detection in clinical applications is discussed. The temperature‐sensitive fluorescent probe is a “black box” to many researchers. This review aims to open a window on the prospect of the noninvasive in vivo detection of temperature which is helpful to deeper understand this rich research area.

Published: October 2022

AbstractIn this study, as the last step of a longitudinal study of the impact of social learning and gamification methodologies on learning results in higher education, we have recorded the activity in a software platform based on Moodle, specially built for encouraging online participation of the students to design, carry out and evaluate a set of learning tasks and games, during two consecutive editions of an undergraduate course. Our aim is to confirm the relationships between the patterns of accomplishment of the gamified activities and the network structure of the social graphs associated with the online forums with knowledge acquisition and final outcomes. For this purpose, we have offered two learning paths, traditional and novel, to our students. We have identified course variables that quantitatively explain the improvements reported when using the innovative methodologies integrated into the course design, and we have applied techniques from the social network analysis (SNA) and the machine learning/deep learning (ML/DL) domains to conduct success/failure classification methods finding that, generally, very good results are obtained when an ensemble approach is used, that is, when we blend the predictions made by different classifiers. The proposed methodology can be used over reduced datasets and variable time windows for having early estimates that allow pedagogical interventions. Finally, we have applied other statistical tests to our datasets, that confirm the influence of the learning path on learning results.
Self‐Assembled Micro‐Sized Hexagons Built from Short DNA in a Crowded Environment

Published: October 2022

AbstractDNA programmable structures of various morphologies have attracted extensive attention due to their potential for materials science and biomedical applications. Here, we report the formation of micro‐sized hexagons via assembly of only one pair of short double‐stranded DNA in buffer‐salt poly(ethylene glycol) solution. Each DNA strand had complementary bases with a two‐base overhang. The procedure of heating and subsequent cooling of blunt‐ended double‐stranded DNA resulted in different assemblies. These results indicated that end‐to‐end adhesion at the terminals induced by complementary overhangs were required to construct the hexagonal DNA assemblies. The stable formation of the hexagons was highly dependent on heating temperature. In addition, concentration adjustments of DNA and poly(ethylene glycol) were essential. Circular dichroism spectral measurements and polarization microscopy observations indicated parallel alignment of double‐stranded DNA in the hexagonal platelet. Self‐assembled micro‐sized hexagons composed of simple building blocks may have great potential for future biomedical device development.

Published: October 2022

AbstractDDX46, a member of DEAD‐box (DDX) proteins, is associated with various cancers, while its involvement in the pathogenesis of breast cancer hasn't been reported so far. The study demonstrated the overexpression of DDX46 in human breast cancer cells and tissue samples, and correlated with high histological grade and lymph node metastasis. Downregulation of DDX46 in the breast cancer cell lines inhibited their proliferation and invasiveness in vitro. Furthermore, the growth of MDA‐MB‐231 xenografts was suppressed in nude mice by DDX46 knockingdown. Taken together, our findings suggest that DDX46 is an oncogenic factor in human breast cancer, and a potential therapeutic target.

Experiments and Computational Fluid Dynamics on Vapor and Gas Cavitation for Oil Hydraulics
Authors: Osterland Sven , Günther Lennard , Weber Jürgen 
Published: October 2022

AbstractA compressible Euler‐Euler computational fluid dynamics (CFD) model for vapor, gas, and pseudo‐cavitation in oil‐hydraulic flows is presented. For vapor, the Zwart‐Gerber‐Belamri (ZGB) model is used and for gas cavitation, the Lifante model. The aim is to determine the empirical parameters within the cavitation models for hydraulic oil by comparing CFD results to experiments in a realistic valve. The cavitating flow is visualized and measured for numerous operating points. By degassing, states of pure vapor cavitation are generated. The major findings are: (1) large eddy simulation turbulence modeling is essential, (2) vapor cavitation in mineral oil can be simulated very well with the ZGB model using the determined parameter, and (3) gas cavitation model provides useful results although not all details can be reflected and its scope is limited.
A cost‐effective approach to generate accurate correlations via analyzing a minimum number of data points; Case study on the convection heat transfer problem
Authors: Darbandi Masoud , Jalali Ramin 
Published: October 2022

AbstractIt is very common in the heat transfer area to analyze and design heat equipment using the past available heat correlations. Basically, demanding higher‐accuracy correlations enforces the heat laboratories to test and collect larger banks of laboratory data. However, this conversely affects the laboratory cost. Therefore, it becomes challenging to create new approaches that let the correlation developers use smaller experimental datasets and provide correlations with sufficient accuracies. To surmount this challenge, the present work develops a new approach that benefits from the computational fluid dynamics method as a reliable and cheap tool and adequately enriches the original, insufficient dataset. Then, suitable enhanced correlations are developed using the new enriched experimental‐numerical‐based dataset. In parallel, the artificial neural network (ANN) is used to enrich the original insufficient dataset separately. Using this experimental‐ANN‐based dataset, it provides a totally ANN‐based correlation. It is shown that the results of enhanced correlations are as accurate as those of the ANN‐based correlation. However, the point is that the use of the present approach is about 100 times faster than using the ANN. The typical forced convection heat transfer through a pipe is examined here to show the capabilities of the current approach.

AbstractInvited for this month's cover is the group of Daniel R. Sørensen at the University of Aarhus (Denmark) and at the University of Lund (Sweden). The cover picture shows a battery cell designed for in operando neutron powder diffraction. The picture seeks to illustrate the experiment process where lithium ions are moving into the crystal structure of the battery cathode during discharge. This leads to changes in the crystal structure that are very important to understand for optimizing the battery materials. These structural changes are probed in operando by neutron powder diffraction, and neutrons are especially suited for probing the location of Li‐ion compared with similar techniques such as X‐ray diffraction. The beauty of using neutrons is also that their penetrating power allows for investigating the battery without the need for windows of any kind.
