. Data confidentiality and security are critical in data communication, both for the purpose of shared security, and for individual privacy. Computer users who want their data unknown to unauthorized parties are always trying to work out how to secure the information that will be communicated or that will be stored. Protection against data confidentiality is increasing, one way is by applying cryptographic science. Cipher Block Chaining (CBC), this mode is a feedback mechanism on a block, and in this case the result of the previous block encryption is feedback into the current block encryption. The trick is to block the current plaintext in XOR first with the ciphertext block of the previous encryption result, then the result of this XOR-ing goes into the encryption function. With CBC mode, each ciphertext block is calculated not only on its plaintext block but also on the entire previous plaintext block. The author tries to co-create a text encoding to secure the data with the Cipher Block Chaining (CBC) cryptographic method.

Attempts have been made to understand the behaviour of the monsoon rains for which excellent data sets are available covering the period of 1871-1988. There are two discontinuities (sudden or abrupt change periods) noticed in the rainfall series in the years 1894 and 1961 and the country's rainfall series has passed through four different epochs.

Three important families of circulation parameters, mainly (i) conditions over Indian region, (ii) cross equatorial flow over Indian Ocean reg1on and (iii) southern oscillation, Which are well associated with all India monsoon rainfall have been examined for the period 1951-80 and results are presented. These associations can be utilized for the prediction of the monsoon rains.

Published: February 2022

Frequency analysis of rainfall data for 1.0 stations is carried out to identify rainfall characteristics in three regions with rainfall greater than 2000 mm, rainfall in the 1000-2000 mm range and rainfall in the range group of 500-1000 mm. The data thus generated indicated that both excess and deficit rainfall periods could occur within a cropping season at most stations located in three, groups. While one day storm rainfall is maximum at Dapoli, it is minimum at Ludhiana. However, short period excess rainfall occurs at each station during which water could be harvested for recycling. Crops characteristics of two major crops, i.e., rice and wheat are discussed which also indicate that in both cases excess and deficit of water could affect yield. The minimum yield of rice is reported from stations in the 1000-2000 mm range group where periods of water stress as well as
excess water occur during c~itica.1 periods and affect the yield. Although conventional irrigation could firm up, to some extent, the uncertainly ill supply of water during monsoon and partly during rabi season, it does not help to overcome problems related to excess water. A farm/community pond based storage and recycling technology is suggested. The technology is feasible and justifiably a better alternative to conventional irrigation, particularly in sub-humid and humid regions, and is relatively cheaper. Preliminary analysis and results are encouraging enough to suggest that the technology could be tried and evaluated at more stations.

Agriculture is a strategic land for economic development. This is supported by the fact that Indonesia had around 8 million hectares of paddy fields in 2017, which has not been added to the area of land, and land that is temporarily not being cultivated. With this area, of course, it can be calculated the amount of agricultural products obtained. But in reality, the level of poverty in Indonesia is still dominated by rural communities which incidentally are farmers. This also happened to the people in Desa Ngembal, Kecamatan Tutur, Kabupaten Pasuruan, where the economic development of the village had not been significant for the last ten years. The socialization carried out aims to provide knowledge to the people of Desa Ngembal in developing village potential that is still minimal in utilization. The socialization explained about how to turn agricultural products into business products that have a selling power so that they can support the welfare of the community. In this socialization it was also conveyed about the procedures for managing business finances, including marketing business products and digital-based marketing strategies that could reach more consumers so as to expand market share.

This research applied a nanostructured electrochemical sensor with a screen-printed electrode (SPE) for examining the dopamine (DA) electrocatalytic oxidation when uric acid (UA) was present. Cu(salophen) nanostructured modified SPE Cu(salophen)/SPE was employed to investigate the electrochemical behavior of DA. At optimal pH (pH 7.0), oxidation of DA at the modified electrode takes place at a potential around 100 mV less positive than at the unmodified SPE. Chronoamperometry was used to determine the diffusion coefficient of DA (D = 1.96×10-5 cm2 s-1). Differential pulse voltammetry (DPV) showed linear response in the range between 0.2-450.0 μM for DA. The limit of detection (LOD) of DA was computed to be 0.05 μM. Moreover, Cu(salophen)/SPE was employed for determining DA in the presence of UA using DPV. The DPV results showed that at the modified electrode, two well-separated oxidation peaks of DA and UA could be obtained at potentials of 180 and 325 mV, respectively. This separation forms the basis for the co-detection of these two materials on the surface of Cu(salophen)/SPE. This sensor was then employed to determine DA and UA in real specimens.

Published: February 2022

Oxide materials of Bi2TixV1-xO5,5-δ have been synthesized by means of conventional solid state reaction method. Substitution of Ti atom for the V sites leads to the formation of single phase Bi2TixV1-xO5,5-δ material with I4/mmm space group of tetragonal structure as well as gives results in large grain size and good sinterability of the ceramic material. With Ti concentration of x = 0.2, sample without the presence of porous could be obtained. The ionic conductivity of Bi2TixV1-xO5,5-δ increases significantly with the presence of Ti atoms. This Ti substitution also reduces phase transition temperatures in Bi2TixV1-xO5,5-δ materials. The conductivity data and scanning electron microscope images show that the Ti concentration in Bi2TixV1-xO5,5-δ could be applied as much as x = 0.2, which is higher than reported before and it still gives better properties.

Dimethyl Carbonate (DMC)-plasticized chitosan-based polymer electrolytes were prepared in the present work. The sample 37.5 wt% chitosan - 37.5 wt% NH4CF3SO3 - 25 wt% DMC showed the highest conductivity of (1.95±0.15) x 10-6 S/cm. From calculated values obtained using the Rice and Roth model, the increase in conductivity is due to the increase in the number density of mobile ions. Universal Power Law was used to analyze the AC conductivity of the sample. Arrhenius behavior was observed in the plot of hopping frequency; ωP against temperature. The AC conductivity master curve was obtained for the highest conducting sample when scaled vertically by σ and horizontally by ω .

Published: February 2022

AbstractAlthough ether‐based electrolytes have gradually been identified as a vital factor to achieving the excellent electrochemical performance observed in transition metal sulfide (TMS) anodes in sodium‐ion batteries (SIBs), there is still a lack of a fundamental understanding about the origin of the positive effect of ether‐based electrolytes on TMS anodes. Herein, a microspherical CoS2 anode has been taken as a representative of TMS. It has been demonstrated that the sodiation process involves not only a traditional conversion reaction taking place between solid‐state CoS2 and Na2S, but also a solid–liquid phase conversion process between active materials and soluble sodium polysulfide (Na2Sn, 2 < n < 8). More importantly, it is first revealed that the long‐term stability and the reversibility of CoS2 anode are mainly due to the solid–liquid conversion behavior, which makes bulk CoS2 gradually develop into a stable porous structure with fast Na+ transport kinetics and small stress/strain during cycling. Consequently, the CoS2 electrode delivers remarkable long‐cycle life with an ultrahigh capacity retention rate of 94.8% even after 1500 cycles at 2 A g−1 (only 2.13 mAh g−1 fading per 100 cycles) and high volumetric capacity of 949 mAh cm−3 at a high active material loading of 3.3 mg cm−2.

Published: February 2022

AbstractThe development of ionic conductors with extreme stretchability, superior ionic conductivity, and harsh‐environment resistance is urgent while challenging because the tailoring of these performances is mutually exclusive. Herein, a hydrophobicity‐constrained association strategy is presented for fabricating a liquid‐free ion‐conducting fluorinated elastomer (ICFE) with microphase‐separated structures. Hydrophilic nanodomains with long‐range ordering and selectively enriched Li ions provided high‐efficient conductive pathways, yielding impressive room‐temperature ionic conductivity of 3.5 × 10–3 S m–1. Hydrophobic nanodomains with abundant and reversible hydrogen bonds endow the ICFE with superior damage‐tolerant performances including ultrastretchability (>6000%), large toughness (17.1 MJ m–3) with notch insensitivity, antifatigue ability, and high‐efficiency self‐healability. Due to its liquid‐free characteristic and surface‐enriched hydrophobic nanodomains, the ICFE demonstrates an extreme temperature tolerance (−20 to 300 °C) and unique underwater resistance. The resultant ICFE is assembled into a proof‐of‐concept skin‐inspired sensor, showing impressive capacitive sensing performance with high sensitivity and wide‐strain‐range linearity (gauge factor to 1.0 in a strain range of 0–350%), excellent durability (>1000 cycles), and unique waterproofness in monitoring of complex human motions. It is believed that the hydrophobicity‐constrained association method boosts the fabrication of stretchable ionic conductors holding a great promise in skin‐inspired ionotronics with harsh‐environment tolerance.

AbstractIntegrating photoactive proteins with synthetic nanomaterials holds great promise in developing optoelectronic devices whereby light, captured by a antenna protein, is converted to a modulated electrical response. The protein–nanomaterial interface is critical to defining optoelectronic properties; successful integration of bionanohybrids requires control over protein attachment site and a detailed understanding of its impact on device performance. Here, the first single‐walled carbon nanotube (SWCNT) bio‐optoelectronic transistor enabled by the site‐specific direct interfacing with a green fluorescent protein (GFP) via genetically encoded phenyl azide photochemistry is reported. The electrical behavior of individual semiconducting SWCNTs depends on the protein residue coupling site and provides the basis to design eco‐friendly phototransistors and optoelectronic memory. Attachment at one GFP residue proximal to the chromophore produces a wavelength‐specific phototransistor. The bio‐transistor can be switched off in less than 38 s with responsivity up to 7 × 103 A W−1 at 470 nm. Attachment via a second residue distal to the chromophore generates optoelectronic memory that show rapid and reproducible conductivity switching with up to 15‐fold modulation that is restored on the application of a gate voltage. Therefore, photoactive proteins, especially GFP, can be realized as a key material for novel single‐molecule electronic and photonic devices.

AbstractPolarized spectroscopic photodetection enables numerous applications in diverse areas such as sensing, industrial quality control, and visible light communications. Although organic photodetectors (OPDs) can offer a cost‐effective alternative to silicon‐based technology—particularly when flexibility and large‐area arrays are desired—polarized OPDs are only beginning to receive due research interest. Instead of resorting to external polarization optics, this report presents polarized OPDs based on directionally oriented blends of poly(3‐hexylthiophene) (P3HT) and benchmark polymer or nonfullerene acceptors fabricated using a versatile solution‐based method. Furthermore, a novel postprocessing scheme based on backfilling and plasma etching is advanced to ameliorate high dark‐currents that are otherwise inherent to fibrillar active layers. The resulting polarized P3HT:N2200 OPDs exhibit a broad enhancement across all principal figures of merit compared to reference isotropic devices, including peak responsivities of 70 mA W−1 and up to a threefold increase in 3 dB bandwidth to 0.75 MHz under parallel‐polarized illumination. Polarization ratios of up to 3.5 are obtained across a spectral range that is determined by the specific donor–acceptor combinations. Finally, as a proof‐of‐concept demonstration, polarized OPDs are used for photoelasticity analysis of rubber films under tensile deformation, highlighting their potential for existing and emerging applications in advanced optical sensing.
