The essential and fatty oils were investigated and a quantitative analysis of the root, green and stem parts of F. Longipedunculata was performed by GC-MS and HPLC-TOF/MS and their antioxidant (DPPH method) activities and potential binding of phytochemicals against SARS-CoV-2 nucleocapsid were determined using Molegro Virtual Docker software. In the root part of the plant, the prominent components of oil were β-phellandrene (53.46%), ocimene (6.79%), 4-terpineol (5.94%) and santalol (5.03%). According to the quantitative results, vanillic acid (141.35 mg/kg), ferulic acid (126.19 mg/kg) and 4-hydroxybenzoic acid (119.92 mg/kg) were found in the roots; quercetin-3-β-O-glycoside (1737.70 mg/kg), quercetin (531.35 mg/kg) and ferulic acid (246.22 mg/kg) were found in the in the green part; and fumaric acid (2100.21 mg/kg), quercetin-3-β-O-glycoside (163.24 mg/kg), vanillic acid (57.59 mg/kg) were detected in the stem part. The antioxidant activity of all parts of the plant was higher than the control with BHT. Silibinin, rutin, and neohesperidin exhibited a stronger affinity than nucleotides. In the silico analysis, many of the phytochemicals were attached with strong hydrogen-bonds and electrostatic effects to the amino acids to which nucleotides are bound. The results indicated that the plant showed antioxidant effects and can be effective against SARS-CoV-2 thanks to the different phytochemical compounds it contains.

Published: March 2022

Tropical country like Malaysia is rich with residual soil and nurtured with high rainfall amount on average 2,550 mm per year. From 2009 until 2018, there are many landslide events reported in the news at Ranau, Sabah and Canada Hill Miri, Sarawak that occurred during rainy season and the landslide recurs within same location over the years. The objective of this study is to determine the relationship of landslide events with geological condition and rainfall at Ranau, Sabah and Canada Hill Miri, Sarawak. Historical landslide data were obtained from local news, previous researchers, and local authorities. Integrated review was conducted to meet the objective. In summary, both areas are prone to landslide due to the high average amount rainfall recorded and the geological properties that are susceptible to landslide occurrence namely shale interbedded with sandstone. Sandstone and shale contact are easily accessible by water weaken the contact surface lead to landslides incidents. Besides, Shale classified as highly plastic soil due to high amount of clay. Clay soil depends on its matric suction to sustain its strength towards sliding. Thus, increasing of pore pressure from rain infiltration reduce the matric suction and eventually reduce the shear strength. Ranau is located at seismically active area compare to Miri and other locations in Sabah crossing Lobou-Lobou fault, Mensaban fault and Mesilou fault. Theoretically, slope instability due to earthquake happened because the cementation of soil may be broken and lead to lesser roughness between soil surfaces resulting in reduction of internal friction angle and cohesion of soil.
HIGHLIGHTS

Rainfall-induced landslides are the common landslides phenomenon worldwide including East Malaysia.
However, due to the high number of seismic activity, Earthquake-induced landslides should not be neglected as one of slope failure phenomena in East Malaysia
Combinations of both Rainfall and Earthquake are required to be investigated due to the presence of both landslide triggering factors from historical data at East Malaysia

Free‐Form Micro‐Optics Out of Crystals: Femtosecond Laser 3D Sculpturing

Published: March 2022

AbstractOptical crystals are ideal materials for complex functional and durable optical components, but their good stability and hardness bring about difficulties in high‐precision machining and require surface roughness below λ/10. Femtosecond laser ablation is a widely applicable processing method indifferent to material types, but its 3D fabrication capability is limited by the accumulation of ablated debris and rough ablated surface. This work demonstrates a universal and flexible technology for the fabrication of crystalline micro‐optics with required shape and surface roughness for the most demanding optical phase control. The cavitation‐assisted ablation by a direct laser writing mode is followed by a high‐temperature treatment to remove the rough non‐crystalline layer caused by ablation. The annealing at temperatures below the melting point of the crystal reduces the roughness down to ≈2 nm without changing the structure shape. This virtue of maintaining the designed shape without change, which is impossible during thermal morphing of 3D surfaces of glasses, allows for a previously unavailable flexibility of surface finish for the most demanding optical micro‐optical elements made in this study. This universal technology with nanoscale resolution and free‐form 3D manufacturing capability is applicable for various crystals and provides a new way to fabricate micro‐/integrated‐optics and nonlinear optical elements.

AbstractControlling interfacial and surface carrier dynamics associated with nanostructured semiconductors is the key to achieving outperforming electrical and optical characteristics in photoelectrochemical (PEC) devices. A strategy for surface renovation by loading a co‐catalyst (functional nanoparticles or layers) can unambiguously empower the device with superior surface property. In this work, a PEC‐type solar‐blind photodetector based on wide‐bandgap p‐AlGaN nanowires is reported on which Rh–Cr2O3 hybrid structures are rationally loaded. Impressively, the external quantum efficiency of the devices is strikingly boosted from 28.8% to 86.7%, while a record‐high responsivity of 178.3 mA W−1 is achieved, exhibiting one of the highest values among PEC photodetectors. Both experimental insights and theoretical modeling reveal that the initial decoration of Rh nanoparticles facilitate the interfacial carrier transfer and separation while optimizing the hydrogen adsorption energy. After subsequent incorporation of the amorphous Cr2O3 layer, which acts as a molecular sieve, not only can the side reaction over Rh be effectively suppressed, but also the interfacial carrier dynamics and surface chemical reactivity are further boosted, thus contributing to more favorable PEC processes. The work offers a unique synergetic strategy to optimize the surface property of semiconductors for boosting photoresponse performance in aqueous environments for future bio‐ or chemical‐related sensing applications.
Hydrothermal Synthesis of High‐Yield Red Fluorescent Carbon Dots with Ultra‐Narrow Emission by Controlled O/N Elements
Authors: Xian Yingmei , Li Kang 
Published: March 2022

AbstractRed fluorescent carbon dots (r‐CDs) with narrow dual emissions (600 nm and 658–683 nm, full width at half‐maximums (FWHMs) of 20 nm and 30 nm), fluorescence quantum yield of 41.0%, and yield of 83.3% are prepared by hydrothermal method using o‐phenylenediamine as precursor and inorganic oxidant as yield enhancer, and they have graphite nitrate‐like structures. The long‐wavelength side emission is aggregation‐induced emission (AIE). A logarithmic relationship between the AIE wavelength (y) and the concentration (x) (y = 8.853ln(x) + 688.53, R = 0.998) is found. This regularity and the high monochromaticity of AIE are related to the existence of highly ordered structures proved by X‐ray diffraction. Its intrinsic emission (FWHM: 20 nm) is the narrowest among the r‐CDs prepared by hydrothermal method. The reason is that the decrease of oxygen content makes the FWHMs become narrow, and the decrease of the pyridine nitrogen content and the increase of pyrrole nitrogen content make them narrower further. The Fourier‐transform infrared spectra and control experiment prove that oxidative polymerization is a necessary preparation step. The linear relationship between the amount of the oxidant and the CDs yield indicates that the yield can be increased only by increasing the conversion rate of the polymerization process.
Smaller species but larger stages: Warming effects on inter‐ and intraspecific community size structure
Authors: Uszko Wojciech , Huss Magnus , Gårdmark Anna 
Published: March 2022

AbstractGlobal warming can alter size distributions of animal communities, but the contribution of size shifts within versus between species to such changes remains unknown. In particular, it is unclear if expected body size shrinkage in response to warming, observed at the interspecific level, can be used to infer similar size shifts within species. In this study, we compare warming effects on interspecific (relative species abundance) versus intraspecific (relative stage abundance) size structure of competing consumers by analyzing stage‐structured bioenergetic food web models consisting of one or two consumer species and two resources, parameterized for pelagic plankton. Varying composition and temperature and body size dependencies in these models, we predicted interspecific versus intraspecific size structure across temperature. We found that warming shifted community size structure toward dominance of smaller species, in line with empirical evidence summarized in our review of 136 literature studies. However, this result emerged only given a size–temperature interaction favoring small over large individuals in warm environments. In contrast, the same mechanism caused an intraspecific shift toward dominance of larger (adult) stages, reconciling disparate observations of size responses within and across zooplankton species in the literature. As the empirical evidence for warming‐driven stage shifts is scarce and equivocal, we call for more experimental studies on intraspecific size changes with warming. Understanding the global warming impacts on animal communities requires that we consider and quantify the relative importance of mechanisms concurrently shaping size distributions within and among species.
Pupil steerable Maxwellian AR display with gaze matching
Authors: Zou Junyu , Luo Zhenyi , Wu Shin‐Tson 
Published: March 2022

AbstractWe demonstrate a gaze‐matched Maxwellian‐view augmented reality (AR) system with an enlarged eyebox. Three viewpoints are generated by three cholesteric liquid crystal (CLC) off‐axis lenses, respectively. The location, diameter, and diffraction angle of these CLC lenses are designed so that the chief rays of each viewpoint match with the corresponding gaze directions. The CLC lenses have a high diffraction efficiency (up to 98%), large off‐axis angle (60°), and small f‐number, which contributes to the 55° central field of view. Such an AR system exhibits several attractive features for practical applications, including aberration‐free, high optical efficiency, high transmittance for the ambient light, relatively large field of view, compact size, and lightweight.

AbstractOil palm mesocarp fiber (MF) holds the potential to be used as a filler in polymeric biocomposite systems. To further improve the dispersion and interfacial adhesion between the fiber and polymer matrix, MF was treated with sodium hydroxide (NaOH) at different concentrations (1%, 3%, 5%, 8% and 10%) and soaking times(1 h, 4 h, 8 h, 24 h and 48 h). The effects of NaOH solution and soaking duration on the oil residue, thermal stability and surface morphology of the MF were investigated. It was found that the soaking time had a prominent effect on the oil residue content compared to the NaOH concentration. Fourier transform infrared spectra demonstrated that alkaline treatment decreased the peak intensities of the carboxyl group and alkene of the fatty acid (oil) at 1630–1700 cm–1. Meanwhile, the clean and smooth surface of MF was revealed by scanning electron microscopy, indicating the removal of noncellulosic components. The treatment also reduced the degree of crystallinity of MF, as reflected by its melting temperature (Tm) and heat of melting (ΔHm), as measured by using differential scanning calorimetry. MF with oil residue is envisioned to improve the fiber dispersion across the polymer matrix during polymer processing.
