Imaging a force field via an optically levitated nanoparticle array
Authors: Lv 吕 Bihu 碧沪 , Zhang 张 Jiandong 建东 , Li 李 Chuang 闯 
Published: August 2024

Abstract
Levitated optomechanical systems represent an excellent candidate platform for force and acceleration sensing. We propose a force-sensing protocol utilizing an optically levitated nanoparticle array. In our scheme, N nanoparticles are trapped in an optical cavity using holographic optical tweezers. An external laser drives the cavity, exciting N cavity modes interacting simultaneously with the N nanoparticles. The optomechanical interaction encodes the information of the force acting on each nanoparticle onto the intracavity photons, which can be detected directly at the output ports of the cavity. Consequently, our protocol enables real-time imaging of a force field.

Abstract
Herein, a physical and mathematical model of the voltage−current characteristics of a p−n heterostructure with quantum wells (QWs) is prepared using the Sah−Noyce−Shockley (SNS) recombination mechanism to show the SNS recombination rate of the correction function of the distribution of QWs in the space charge region of diode configuration. A comparison of the model voltage−current characteristics (VCCs) with the experimental ones reveals their adequacy. The technological parameters of the structure of the VCC model are determined experimentally using a nondestructive capacitive approach for determining the impurity distribution profile in the active region of the diode structure with a profile depth resolution of up to 10 Å. The correction function in the expression of the recombination rate shows the possibility of determining the derivative of the VCCs of structures with QWs with a nonideality factor of up to 4.

Abstract
In the design of satellite systems, it is essential to control the satellite’s position for various reasons, either to have correct communication with a ground station or to make connections with other satellites. In the same way, the positioning of a satellite poses a significant challenge since its behavior is non-linear; due to these issues, several test benches have been developed for the satellite’s position problem. In this review, there will be a journey from the rise of the space age to the latest advances in technology for emulating the satellite’s dynamics.

Abstract
Identification of particles generated by ion collisions in
the NICA collider is one of the basic functions of the Multipurpose
Detector (MPD). The main means of identification in MPD are the
time-of-flight system (TOF) and the time-projection chamber
(TPC). The article considers the optimization of the algorithms of
particles identification by these systems. Under certain conditions,
the use of the statistical Bayesian approach has made it possible to
achieve an optimal ratio of the efficiency of particle
identification and contamination by incorrectly defined particles.

Abstract
Bone is a dynamic tissue that can always regenerate itself through remodeling to maintain biofunctionality. This tissue performs several vital physiological functions. However, bone scaffolds are required for critical-size damages and fractures, and these can be addressed by bone tissue engineering. Bone tissue engineering (BTE) has the potential to develop scaffolds for repairing critical-size damaged bone. BTE is a multidisciplinary engineered scaffold with the desired properties for repairing damaged bone tissue. Herein, we have provided an overview of the common carbohydrate polymers, fundamental structural, physicochemical, and biological properties, and fabrication techniques for bone tissue engineering. We also discussed advanced biofabrication strategies and provided the limitations and prospects by highlighting significant issues in bone tissue engineering. There are several review articles available on bone tissue engineering. However, we have provided a state-of-the-art review article that discussed recent progress and trends within the last 3–5 years by emphasizing challenges and future perspectives.
Bathymetry-constrained ocean geostrophic currents play a key role in shaping the sea ice circulation in the Canada Basin, Arctic Ocean

Published: August 2024

Abstract
Satellite-based observations and a pan-Arctic coupled sea ice-ocean model are utilized to study the effect of ocean geostrophic currents on large-scale sea ice circulation in the Canada Basin, Arctic Ocean. We find that surface winds primarily drive sea ice drifts in the west–east direction, while the geostrophic currents in the Beaufort Gyre promote north–south ice drifts. Wind fluctuations can create variable ice drifts, yet geostrophic currents respond more slowly due to their larger vertical scale, serving as a slowly-evolving conveyor belt for maintaining the anticyclonic ice circulation. It is further demonstrated that the bathymetry can regulate the movement of sea ice via constraining the expansion of ocean circulation. This mechanism is indirect in the sense that the ice is far from the seafloor. Our research underscores the necessity of considering the bathymetry-constrained geostrophic currents in understanding Arctic sea ice dynamics. With the rapid retreat of Arctic sea ice, the multi-scale interactions between ice drifts and ocean currents may have significant implications for the Arctic ecosystem, climate, and shipping corridors.

Abstract
A largenumber of oil palm trees are replanted every year. Considering the extent of replanting and OPT’s high starch and sugar content, it was determined to be a potential raw material for bioethanol production. This study conducted ethanol production by simultaneous saccharification and fermentation of starch-rich powder extracted from oil palm trunks. Fermentation was conducted on a 100 L bench scale to evaluate the feasibility and further development of the process before the process is implemented at a larger scale. The preparation of the starch-rich flour involves shredding, drying, and screening of the trunks until the starch-rich powder passes through an 80-mesh sieve. Furthermore, starch was liquefied and partially saccharified. Subsequent saccharification was performed simultaneously with fermentation. The initial total sugar content was adjusted to 15 % w/v and starch was enzymatically hydrolyzed using commercial α-amylase (Liquozyme) and glucoamylase (Novozyme) produced by NOVO. Fermentation was performed using Saccharomyces cerevisiae Hakken No. 1. Since the starch-rich flour contains useful nutrients and growth factors for microbes, the fermentation medium only required the addition of a nitrogen source (urea 1 g/L). The ethanol content after fermentation was approximately 8.7 % v/v with a fermentation ratio of 88.8 %. These results were obtained at a fermentation time of 60 h. One OPT yields 80 kg of starch-rich powder, equivalent to 33 liters of bioethanol.

Published: August 2024

Abstract
Liquid smoke-based edible coatings have garnered considerable attention in the food processing and post-harvest industry due to their environmentally friendly attributes and their ability to extend the shelf life of perishable goods. This study investigates the antimicrobial efficacy of edible coatings formulated using chitosan and young coconut shell liquid smoke against both gram-negative bacteria (Escherichia coli and Salmonella typhimurium) and gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus). The liquid smoke was produced via the pyrolysis of young coconut shells at temperatures of 300 (T1), 340 (T2), 380 (T3) and 420ºC (T4). The edible coatings were prepared by blending 2% (v/w) liquid smoke with varying chitosan concentrations of 0.5 % (Ch 0.5), 1% (Ch 1) and 1.5% (Ch 1.5). Antibacterial activity assessments were conducted using the disc diffusion method (Kirby Bauer). The findings reveal that the antibacterial efficacy of the edible coatings against each bacterial strain is influenced by both the pyrolysis temperature and the concentration of chitosan employed. Liquid smoke derived from T4 pyrolysis exhibited the highest inhibitory potential, except for Bacillus subtilis. Notably, the most pronounced antimicrobial activity against Salmonella typhimurium was observed with the T4Ch1.5 edible coating. Specifically, at T4Ch1.5, the inhibitory zones for Escherichia coli, Salmonella typhimurium, Bacillus subtilis, and Staphylococcus aureus were measured at 7.65 mm, 8.30 mm, 7.55 mm, and 7.23 mm, respectively. The results underscore the promise of edible coatings comprising a combination of chitosan and young coconut shell liquid smoke as potential candidates for preserving food and agricultural products, offering both protection and antibacterial properties.

Abstract
This research aimed to determine the effect of the type of rice and the source of anthocyanin extract on the physical, chemical and organoleptic properties of the instant rice produced, to obtain instant rice with high antioxidant activity but which is still preferred by consumers. Anthocyanin extracts from butterfly pea flowers (B1), mangosteen peel (B2) and dragon fruit peel (B3) were made from 10 g of powder which was macerated in 100 ml of boiled distilled water for 15 minutes. Rice from varieties IR-64 (A1), rojolele (A2) and ciherang (A3) that have been sorted, 100 g each, washed clean and drained, then each added with anthocyanin extract B1, B2 and B3 in a ratio of 1 :1 (w/v), then mixed. Each rice to which anthocyanin extract has been added is then cooked using a rice cooker for 15 minutes, then removed and air-dried for 5 minutes, then followed by drying using an oven at 60°C for 24 hours until dry instant rice is obtained. The results of the study showed that the type of rice had an effect on the color preference of instant rice, but had no effect on antioxidant activity, water content, reducing sugar content, rehydration time, aroma preference, texture preference and taste preference. The source of anthocyanin extract affected on the antioxidant activity and color preference of instant rice, but has no effect on the water content, rehydration time, aroma preference, texture preference and taste preference. The instant rice made from IR 64 which added butterfly pea flowers anthocyanin extract is recommended because it contains the highest antioxidants with antioxidant activity of 76.48%, water content of 7.18%, rehydration time of 10.18 minutes, reducing sugar content of 0.37% and an average favorability value of 4.66 (somewhat like).

Published: August 2024

AbstractThis research aimed to determine the physicochemical quality of beef sausages modified with transglutaminase enzymes (TGase) and external proteins. The physical properties of sausages include water holding capacity, cooking loss, pH, and tenderness. The chemical properties of sausages are water content, ash content, protein content and fat content. The treatment consisted of a control, namely the addition of STTP 0.3% (w/w), TGase 0.03% (w/w), TGase + skim milk 3.5% (w/w), TGase + SPI 3.5% (w/w), and TGase + WPI 3.5% (w/w). The results showed that the addition of transglutaminase enzyme or a combination with external protein significantly (P<0.05) improved the physical quality of sausages such as increasing water holding capacity and tenderness as well as reducing cooking losses and pH. The chemical quality of sausages also showed significant results (P<0.05), namely reducing water and fat content, and increasing ash and protein content in sausages. Comparison between TGase + SPI and TGase + WPC did not show significantly different results. The conclusion of this research is that the physicochemical properties of beef sausage can be modified using the TGase enzyme, but it would be better if TGase was combined with an external protein.

Abstract
Hydrosol is a by-product of the distillation process which contains water-soluble compounds. Hydrosols are becoming increasingly popular in the cosmetic, pharmaceutical, and food industries. Lemongrass (Cymbopogon citratus) is an herbal plant widely used as a flavoring agent in herbal teas, frozen desserts, and meat products. The water extract of lemongrass leaves contains alkaloids, phenolics, tannins, and flavonoids, which have antioxidant and antibacterial properties. This research aims to identify the bioactive components and bioactivity of essential oils, hydrosols, and solvents used in the distillation of lemongrass leaves (Cymbopogon citratus). Fresh lemongrass leaves were water steam distilled for three hours. The antioxidant activity of lemongrass leaf essential oil, hydrosols, and solvents was determined using the DPPH assay. The chemical composition of lemongrass leaf essential oil, hydrosol, and solvent was analyzed using GCMS. The GCMS test results showed that the essential oil, hydrosol, and solvent of lemongrass leaves had different chemical components. There are 17 compounds found in the lemongrass leaf essential oil, with 5 major compounds namely E-citral (44.22%), Z-citral (32.78%), β-myrcene (15.66%), trans-4,5-epoxi-carane (3.51%) and geranyl acetate (0.82%). In the hydrosol, 3 compounds were identified, namely isolongifolene (18.81%), epiglobulol (64.09%), and 4,7-Epoxy-1H-isoindole-1,3(2H)-dione (17.10%). One compound, (Z,Z)-3,9-cis-6,7-epoxy-nonadecadiene, has been identified in the solvent. The antioxidant activity of hydrosols and solvents is the same as the lemongrass leaf essential oil. The findings of this study suggest that distillation waste in the form of hydrosols and distillation solvents for lemongrass leaves has the potential to be functional ingredients that may have applications in both the food and non-food sectors.

Published: August 2024

Abstract
Food and nutrition are very important and strategic elements in increasing national productivity and improving the population’s quality of life. FAO states that people suffering from malnutrition in Indonesia are caused by food consumption patterns which are dominated by the grain group. The low consumption of the tuber group is due to the availability of this food ingredient, besides being low, access to it is also difficult, especially in the dry season, due to the dormancy of the tubers. Hausa potatoes, taro, and yam are types of tubers that have not been widely developed by the community. Exploration activities carried out in East Java are expected to increase the diversity of local food sources, which have high production potential and functional food properties, and also to look for superior accessions that can be developed as functional food. The evaluation method for several accessions was carried out using observing morphological descriptions and evaluating nutritional composition. Data were analyzed by clustering analysis and comparing the nutrition content of tubers with rice. The exploration results showed several variations in characters in the accessions of Hausa potato, taro, and yam. From the results of this exploration, the accessions were grouped into 2 large groups, based on tuber size and tuber color, where these characteristics are supporting components in the development of functional food. Hausa potato accessions BWI 3, yam accessions Yam_05, Yam_02, and Yam_04, as well as taro accessions MLG 2 and LMJ 2 can be used as functional food candidates to replace rice.
