ABSTRACTCapsinoids may exert ergogenic effects on resistance exercises. However, the acute effects of capsinoids on neuromuscular performance in humans are unknown. Here, we aimed to investigate the acute effects of dihydrocapsiate on lower‐ and upper‐body neuromuscular performance parameters in resistance‐trained individuals. 25 young adults (n = 6 women; age = 26 ± 3 years; body mass index = 24.3 ± 2.8 kg/m2) with ≥ 1‐year resistance training experience were included in this triple‐blind (participants, intervention researchers, and data analysts were blinded), placebo‐controlled, crossover study. Lower‐ and upper‐body ballistic strength (countermovement jump [CMJ] height and bench press throw [BPT] peak velocity), maximum dynamic strength (estimated 1 repetition maximum in squat and bench press [BP]), and strength‐endurance (mean set velocity [squat] and number of repetitions to failure [bench press]) were assessed in 2 independent sessions (≥7 days separation). Participants ingested 12 mg of dihydrocapsiate or placebo 30 min before each trial. We found no significant differences between dihydrocapsiate and placebo conditions in ballistic strength, (CMJ height 33.20 ± 8.07 vs 33.32 ± 7.85 cm; BPT peak velocity 2.82 ± 0.77 vs 2.82 ± 0.74 m/s) maximal dynamic strength (estimated squat 1RM: 123.76 ± 40.63 vs 122.66 ± 40.97 kg; estimated BP 1RM: 99.47 ± 43.09 vs 99.60 ± 43.34 kg), and strength‐endurance (squat mean set velocity 0.66 ± 0.07 vs 0.66 ± 0.05 m/s; number BP repetitions to failure 13.00 ± 3.56 vs 13.00 ± 4.78) (allP ≥ 0.703). We conclude that dihydrocapsiate does not acutely improve neuromuscular performance in trained young adults.
Spin-polarization control of in-plane scattering in arrays of asymmetric U-shaped nanoantennas
Authors: Sadeghi Seyed M , Roberts Dustin T , Gutha Rithvik R 
Published: July 2023

Abstract
We study projection-enabled enhancement of asymmetric optical responses of plasmonic metasurfaces for photon-spin control of their far field scattering. Such a process occurs by detecting the light scattered by arrays of asymmetric U-shaped nanoantennas along their planes (in-plane scattering). The nanoantennas are considered to have relatively long bases and two unequal arms. Therefore, as their view angles along the planes of the arrays are changed, they offer an extensive range of shape and size projections, providing a wide control over the contributions of plasmonic near fields and multipolar resonances to the far field scattering of the arrays. We show that this increases the degree of the asymmetric spin-polarization responses of the arrays to circularly polarized light, offering a large amount of chirality. In particular, our results show the in-plane scattering of such metasurfaces can support opposite handedness, offering the possibility of photon spin-dependent directional control of energy routing.

Published: July 2023

Abstract
This study explores important parameters for achieving a high-level positional control of DNA-nanoparticle hybrid structures by drop-casting onto a pre-structured silicon surface, in which the active adsorption sites were defined using electron beam lithography. By confining the adsorption sites to the scale of the DNA origami, we create multi-dimensional patterns and study the effect of diffusion and hybrid nanostructure concentration in the liquid on site occupation. We also propose a physical diffusion model that highlights the importance of surface diffusion in facilitating the adsorption of hybrid nanostructure onto active sites, particularly for two and one-dimensional adsorption sites. Our study shows prominent results of the hybrid nanostructure’s selective adsorption, indicating high adsorption efficiency and precise control over the position, as well as the spatial orientation. We anticipate similar results in related systems, both in terms of different surfaces and similar DNA structures. Overall, our findings offer promising prospects for the development of large-scale nanoarrays on micrometer-scale surfaces with nanometer precision and orientation control.

Published: July 2023

Abstract
The creep mechanical properties of rock under dry-wet cycles are of great significance for studying the long-term aging stability of engineering rock and soil. In the past, there were few studies in this area, and most of the dry-wet cycle tests on rock samples did not conform to the actual stress state of the rock. In view of the shortcomings of these studies, this paper innovatively carried out the dry-wet cycle test of the rock under the continuous state of the stress field, and studied its mechanical properties. The specific method is to take carbonaceous shale as the research object, and use the soft rock shear rheological test system independently developed by our research group to carry out the shear creep test of carbonaceous shale under the action of dry-wet cycle. The test results show that the creep full-time curves of carbonaceous shale under different dry-wet cycles show a step-shaped curve shape. The dry-wet cycle has a significant effect on the deformation characteristics of carbonaceous shale. With the increase of the number of dry-wet cycles, the instantaneous strain of the rock gradually increases, the instantaneous shear modulus decreases from 596.650 MPa at 0 times to 365.199 MPa at 12 times, and the attenuation rate reaches 38.79%. The creep strain and cumulative creep strain become larger, the stress required for accelerated creep decreases from 3.29 MPa to 2.75 MPa, and the accelerated creep time in the third stage increases from 11.892 h to 5.316 h, and the creep effect is more significant. The long-term strength of carbonaceous shale decreases from 3.05 MPa to 2.49 MPa, and the decrease increases with the increase of dry-wet cycles. The more the number of dry-wet cycles, the smaller the undulation of the shear failure section of the carbonaceous shale, and the smoother the surface. The research results have important guiding significance for the long-term aging stability analysis of engineering rock and soil mass subjected to repeated dry-wet cycles.

Abstract
Distinct models involving nonlinearity are mostly appreciated for illustrating intricate phenomena arise in the nature. The new (3+1)-dimensional generalized nonlinear Boiti-Leon-Manna-Pempinelli (BLMP) model describes the dynamical behaviors of nonlinear waves arise in incompressible fluid. This present effort deals with the well-known governing BLMP equation by adopting two efficient schemes, namely improved tanh and improved auxiliary equation. As a result, a variety of appropriate wave solutions are made available in different type functions. The gathered solutions are figured out to characterize their internal properties for depicting the relevant phenomena. Diverse wave profiles are noticed in 3D, 2D and contour sense after assigning parameter’s values involved in the achieved solutions. The finding results are comparably different and general due to the existing wave solutions. The employed approaches perform in a great way to construct analytic wave solutions of considered evolution equation and deserve further use in relevant research area.

Abstract
The model for photodegradation with a modified rate constant that was developed and presented in previous study, was generalized for the application of ZnO-based photocatalyst in both thin film and powder form. The applicability of the model was proved on methylene blue discoloration on both types of photocatalysts. The photocatalytic reaction rate was found to be dependent on the depth of the solution in case of small depths for this photocatalyst. This correlataion was valid in both high and low transparency. In addition, the impact of the solution pH on the model pollutant decomposition rate was defined.

Published: July 2023

Abstract
The integrated shear 3-point correlation function ζ
± measures the correlation between the local shear 2-point function ξ
± and the 1-point shear aperture mass in patches of the sky. Unlike other higher-order statistics, ζ
± can be efficiently measured from cosmic shear data, and it admits accurate theory predictions on a wide range of scales as a function of cosmological and baryonic feedback parameters. Here, we develop and test a likelihood analysis pipeline for cosmological constraints using ζ
±. We incorporate treatment of systematic effects from photometric redshift uncertainties, shear calibration bias and galaxy intrinsic alignments. We also develop an accurate neural-network emulator for fast theory predictions in MCMC parameter inference analyses. We test our pipeline using realistic cosmic shear maps based on N-body simulations with a DES Y3-like footprint, mask and source tomographic bins, finding unbiased parameter constraints. Relative to ξ
±-only, adding ζ
± can lead to ≈ 10-25% improvements on the constraints of parameters like As
(or σ
8) and w
0. We find no evidence in ξ
± + ζ
± constraints of a significant mitigation of the impact of systematics. We also investigate the impact of the size of the apertures where ζ
± is measured, and of the strategy to estimate the covariance matrix (N-body vs. lognormal). Our analysis solidifies the strong potential of the ζ
± statistic and puts forward a pipeline that can be readily used to improve cosmological constraints using real cosmic shear data.

Abstract
In order to study the energy output characteristics of multi-component explosives mixed with aluminum powder and emulsified explosives, five groups of emulsified explosives containing aluminum with different proportions were used for underwater explosion experiments and overpressure tests in the air. The experimental data show that when the mass fraction of aluminum powder increases from 0% to 40%, the shock wave energy increases from 0.68 kJ·g-1 to 1.22 kJ·g-1, which increases by 79.41%. Bubble energy increased by 135.66% from 2.44 kJ·g-1 to 5.75 kJ·g-1; the total energy of underwater explosion increased by 123.40% from 3.12 kJ·g-1 to 6.97 kJ·g-1. The explosion overpressure in the air increased by 93.66% from 60.794 KPa to 117.734 KPa. Aluminum powder greatly increases the output level of emulsified explosives. Emulsified explosive containing aluminum has the characteristics of high working capacity and high explosive performance.
Study of Thermal Conductivity of Fluorinated Graphene
Authors: Yan Yunrui 
Published: July 2023

Abstract
With the rapid development of technology and the advent of the 5G era in recent years, the heat dissipation of electronic devices has received great attention. However, the high intrinsic conductivity of ordinary graphene materials limits their potential applications in electronic packaging materials because of their poor thermal management. The results show that fluorinated graphene has excellent heat resistance, corrosion resistance, and strong wear resistance. It can also play a role in lubrication and is commonly used in high-temperature coatings, wear-resistant lubrication coatings and corrosion-resistant coatings because it does not react easily with other substances. Due to the strong electronegativity of fluorine, fluorinated graphene has strong stability and oxidation resistance at high temperatures. Therefore, in this paper, a fluorinated graphene with high compressibility, high thermal conductivity, and high electrical insulation was developed by hydrothermal method assisted by hydrofluoric acid, and the effect on the thermal conductivity of fluorinated graphene was investigated by changing the fluorine-to-carbon ratio (F/C) by adjusting the hydrofluoric acid content. The structure of fluorinated graphene was characterized by SEM and XRD, which proved to be porous and a customized interconnected graphene network with adjustable fluorine coverage. The prepared fluorinated graphene has good insulating properties with a minimum conductivity of 4×10-7 S cm-1 and a thermal conductivity of 1.254 W m-1 K-1, which has been confirmed by the electrical conductivity test results. Meanwhile, because of the porous structure of graphene fluoride, we prepared epoxy resin/fluorinated graphene nanocomposites by vacuum-assisted infiltration process using epoxy resin as the filler material. This material and fluorinated graphene showed outstanding thermal performance during the typical cooling process. The conclusion shows that graphene fluoride and epoxy resin/fluorinated graphene nanocomposites are promising for electronic packaging.

Published: July 2023

Abstract
To evaluate the potential of biodegradable materials in beverage packaging applications, five aquatic simulants and eight different commercial beverages were set up to study the aging effects of PLA-PBAT blends. The experimental data for 6 months consistently indicate that aquatic conditions have a small impact on the weight change and surface characters. PLA-PBAT blends show slow oxidation and decomposition process, which were less than ±1%, like the samples exposed to air. Among different beverages, non-alcoholic and alcoholic drinks showed little difference, while acidic beverages had a relatively remarkable surface erosion effect on the biodegradable materials.

Published: July 2023

Abstract
Sweat analysis is a non-invasive, simple, and convenient means of disease detection, which is extremely useful in human daily supervision. This work demonstrates the design of the nanosilica biosensor for simple, sensitive, and low-cost colorimetric sensing of glucose and pH in sweat. The nanosilica biosensing interface was prepared by chemical vapor deposition, surface modification, superwettable patterning, and sensing regions functionalization. The nanosilica substrate has high mechanical robustness and is stable enough as a biosensing platform. Colorimetric tests enable direct naked-eye observation monitoring of sweat indicators like pH and glucose without the need for electrical or optical apparatus. This will greatly enhance the convenience and reduce costs. The design of a biosensing platform will be made possible by the nanosilica biosensor, which also has significant promise for applications in clinical detection and multicomponent biosensing.

Abstract
To improve the problem that ultrafine hexanitrohexaazaisowurtzite (CL-20) is prepared by the solvent nonsolvent method, which tends to coalesce and automatically affects its thermal properties, the bonding agent @CL-20 core-shell composite energetic materials (ammonium dodecylbenzene sulfonate@CL-20, trimethylsilyl monooleate@CL-20 and boron nitride@CL-20) were prepared by water suspension method. The coated ultrafine CL-20 was characterized by an optical microscope, scanning electron microscope (SEM), Fourier transforms infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC), and its sensitivity was tested according to GJB 772-1997. The results showed that the three bonded dispersants completely coated CL-20, and the crystal form of CL-20 was still ε-. Compared with the raw material CL-20, the characteristic drop increased by 27.5cm at most and the thermal decomposition temperature increased by 4 °C.

Authors: Li Geli 
Published: July 2023

Abstract
The self-made polycarboxylic acid water reducer was used as a dispersant to investigate its influence on the dispersion property of new functional material graphene slurry. The dispersion technology in the preparation process of new functional material and the influence of the dosage of new functional material on the performance of concrete were studied. The results showed that the self-made polycarboxylic acid water reducer as a dispersant can improve the dispersibility of the new functional material graphene in water. When the ultrasonic dispersion time is 40min, it can be used to discharge bubbles in the graphene dispersion solution and improve the strength of concrete. By means of manual mixing, the concrete containing the dispersible liquid of the new functional material has less slump and less expansion loss at 1h, and higher compressive strength at 3 d, 7 d, and 28 d. The 7 d and 28 d compressive strength of concrete can be significantly improved when the content of new functional material graphene dispersion is 0 ∼ 0.23 %, and the optimal content of graphene dispersion is 0.05 %.

Authors: Zhang Meng , Mirza Hasnain Ali , Li Yong 
Published: July 2023

Abstract
Although some papers have studied the formability of fiber metal laminates (FMLs), there is still a lack of a standard criterion for the engineering field. To give a standard for predicting the failure and provide the optimized method of the hydroforming process for FMLs, a comprehensive forming limit curve (FLC) was established by a hydro-bulging test method. The influence of pressure rate (PR), blank holder pressure (BHP), and temperature (T) was studied in this paper. Both theoretical and experimental results showed that the higher BHP and PR have a significant negative effect on limit height, while increased T has a positive effect. Moreover, the semi-cured forming of a real part was evaluated by this FLC for the very first time and the improvement suggestions of process parameters were given based on the comprehensive research. Finally, the real part that met the quality requirements was obtained by numerical simulation and trial production, which verifies the effectiveness of this comprehensive FLC.

Authors: Li Haihua , Gao Yuhua , Zhang Lihui 
Published: July 2023

Abstract
Magnesium hydroxide has good adsorption performance for Cu2+ in wastewater as an adsorbent, while magnesium hydroxide particles carry a lot of electric charges, which makes it difficult for the particles to settle. To solve this problem, the composite of cross-linked starch and magnesium hydroxide IStMg was synthesized. IStMg was prepared by using cross-linked starch and MgSO4·7H2O as raw materials and NaOH as an alkalizing agent, and the adsorption performance of this composite for Cu2+ was tested. In the adsorption experimentials, when ρ

0cu2+=20 mg/L and the dosage of IStMg was 300 mg/L, the removal rate of Cu2+ was 91.7%. The absorption mechanism contains the complexation of the hydroxyl group in magnesium hydroxide to Cu2+ and the ion exchange between Mg2+ and Cu2+.

Abstract
As the main material of aircraft windshield glass, the safety and reliability of aviation plexiglass are very important. YB-3 aviation Plexiglass was used as aircraft windshield material for a four-seater electric aircraft developed in China to explore the mechanism of ultraviolet aging. The artificially accelerated aging test of YB-3 aviation plexiglass was carried out, and the mechanical and thermodynamic system of YB-3 aviation Plexiglass after aging was studied. Through the thermogravimetric dynamic analysis, it is to explore the internal aging mechanism of PMMA photolysis materials, and combined with the mechanical test data to quantitatively and qualitatively reveal the aging law of YB-3 aviation plexiglass under ultraviolet radiation. The results show that the tensile ultimate stress decreases from 72.74 MPa to 45.63 MPa when the aging time reaches 1440 h. During the aging process, the elastic modulus decreased from 4.45 GPa to 3.68 GPa and then increased to 4.12 GPa. The results show that the photolysis of YB-3 aero-plexiglass under ultraviolet radiation first results in the fracture of the polymer and then the production of small molecules, which leads to the decrease of tensile resistance and the improvement of thermal stability of the material.
