摘要: The Internet of Things (IoT) can play a key role in transforming traditional agricultural sector to smart agricultural domain. However, in developing economies the adoption is in the nascent stage. This paper aims to evaluate the critical factors that impact the adoption decision of IoT technology in the Agricultural and Food Supply Chain (AFSC). Based on a comprehensive literature survey and experts’ opinion 24 critical factors were identified. The identified list of factors was categorized int关键词: IoT adoption;Agriculture sector;Food sector;Critical factors;Sustainability;AFSC;AHP;AI;BDA;DEMATEL;ELECTRE;GA;GRA;ICT;IoT;ML;MCDM;NGOs;PLS;RFID;ROI;SC;SEM;SVM;TAM;TISM;TOE;VIKOR;WSNs

摘要: Innovative cities that use Information and Communication Technologies (ICT) while guaranteeing that they meet current generations’ needs for life quality, operating efficiency, and competitive nature are known as Smart Sustainable Cities (SSCs). Green spaces and eco-friendly practices are integrated into the urban area to reduce pollution levels and CO2 emissions and protect the natural resources within the city. Apps for smart cities are designed to control traffic and respond to emergencies in关键词: Information and Communication Technologies (ICT);Internet technology (IT);Energy generation;Storage;Consumption;Smart Sustainable Cities (SSCs)

摘要: The present work recognises 2-(3,4-Dihydroxybenzylidene)malononitrile (Hy34DC) as a photoacid and intramolecular charge transfer (ICT) probe for proton transfer process from solute to solvent at the ground and excited state. Microsolvation and intermolecular H-bonding interactions play a significant role in enhancing the proton transfer process. Solvent-dependent enhancement of proton transfer process is observed comparing the relative intensity of ICT band from UV–Vis results at ground state.

摘要: In virtue of the pliable structure and ample pendent amine groups, the metal-free graphic carbon nitride (g-C3N4, abbreviated as CN) in two-dimensional (2D) morphology could be covalently modified by organic materials to modulate its photoelectrical characteristics. In this work, CN is covalently wrapped by a 2D Schiff-base covalent organic framework (COF, denoted as TMP), which is composed of 2,4,6-tris(4-aminophenyl)− 1,3,5-triazine (TAPT), melem and 1,3,5-triformyl phloroglucinol (TP), by mea关键词: Covalent organic frameworks;Photocatalysis;ICT;Hydrogen evolution

摘要: A salamo-salen-salamo hybrid fluorescent chemical sensor (H4L) was synthesized and characterized. It exhibits high selectivity and sensitivity to Zn2+ in physiological pH range. Meanwhile, its zinc(II) complex (L-Zn2+) continuously responses phosphate anions in DMF/H2O (v/v, 9:1) solution. Moreover, the identification processes are explored using characterization methods such as UV-absorption spectra, IR spectra and ESI-MS spectrum. In addition, the coordination mechanism o关键词: Salamo-salen-salamo based sensor;Multiple response;ICT mechanism;Zn;2+;Phosphate anion

摘要: With progressing digitalisation, negative consequences resulting from the use of information and communication technologies at work are an important topic of debate. With this paper, we contribute to the current discourse by examining how employees mitigate technostress. We transfer theory from psychology to information systems literature by investigating a moderated mediation model where coping was conceptualised as a personal resource in line with the job demands-resources model.

摘要: The effect of ICT use on students’ academic achievement continues to be debated. While positive, negative, and non-significant linear relationships have been reported in the literature, few studies have examined the non-linear relationship between ICT use and academic achievement. Guided by the Opportunity-Propensity framework, this study addressed this gap by examining the non-linear relationships between four types of ICT use and students’ academic achievement.

摘要: Several isolated microgrids (MGs) may exist in remote areas because of the geographical and/or utility investment limitations. The isolated MG has its challenges depending on its configuration, energy sources, and nature of loads resulting in power quality issues. Clustering these MGs based on their relative locations to form several clusters and interconnecting them may provide additional benefits such as improved reliability, stability, and cost-effective operation. This entails the capability关键词: Microgrids (MGs);Marine predator algorithm (MPA);energy management system (EMS);MG central controller (MGCC);MG operator (MGO);Power quality;Dynamic voltage restorer;ADVR;ANN;BESS;CF;COS;CSA;DER;DG;EM;EMS;ESS;FACTS;FAD;FBA;FC;FOPID;FRT;GOA;ICT;ITAE;LC;MG;MGCC;MGO;MPA;MPPT;MT;OM;PEMFC;PID;PM;PQ;VR;PV;SoC;THD;WES;WT

摘要: A series of phenothiazine-based A-π-D-A type ‘push-pull’ molecules containing sites sensitive to external stimuli was designed and synthesized by phase transfer Heck coupling reaction. A positive solvatochromism was observed with an increase in solvent polarity resulting in an enhanced intramolecular charge transfer (ICT). The existence of TICT was prominent in highly polar media such as methanol and water. Single crystal X-ray diffraction revealed the existence of two structures of VPTZ, with t关键词: Acidochromism;Amine sensing;Intramolecular charge transfer (ICT);Moisture sensing;Phenothiazine;Solvatochromism

摘要: TDDFT method was applied to study the excited-state mechanism of a reported fluorescent probe for fluoride and sulfite. Theoretical results showed the excitation of the probe molecule involved an intramolecular charge transfer process. Based on potential energy scanning and frontier orbital analysis, the excited-state proton-transfer process of the fluoride-probe product resulted in the significant red-shifted fluorescence. In contrast, the intramolecular charge transfer process was inhibited by关键词: Excited State;Fluorescent Probe;ICT;TDDFT;ESPT

摘要: Despite the momentous rise in ICT diffusion, and financial development in sub-Saharan Africa (SSA), their plausible joint effect on inclusive growth have not been explored, leaving a lacuna in the literature. This study, therefore, examines the direct and indirect effects of ICT diffusion on inclusive growth in 42 SSA countries over the period 1980–2019. We provide evidence robust to several specifications from the dynamic system GMM to show that: (i) ICT skills, access and usage induce inclusiv关键词: Financial development;Financial inclusion;ICT diffusion;Inequality;Inclusive;Growth;Poverty;Sub-Saharan Africa;D63;E5;G2;I3;L96;O11;O55

摘要: Surgery is still one of the most important means of treating tumors. Fluorescence imaging-mediated surgical navigation and intraoperative phototherapy are considered to be effective ways to improve surgical outcomes. However, the lack of ideal imaging/phototherapy agents continues to be a barrier to their clinical application. Traditional imaging/phototherapy agents present some challenges in living organisms, such as aggregation caused quenching (ACQ), which cause a burst of fluorescent signal 关键词: A;ACQ;ACQphore;AIE;AIEgen;ALP;BBTD;BT;BSA;BZ;CT;D;DSPE-PEG2000;ΔE;ST;EPR;F-127;FLI;HOMO;ICT;ISC;LUMO;MBs;MRI;MSMs;NIR;NIR-I;NIR-II;NLO;NPs;NZ;1;O;2;OLED;OTPA;PAE;PAI;PCE;Pdots;PEG;PET;PDT;PIP;PTI;PTT;PTZ;PSs;QM;QY;RIM;RIR;RIV;ROS;S;n;S;1;S;0;SBR;T;1;T/NT;TPA;TPE;TQ;US;ε;Aggregation-induced emission;Fluorescence imaging;Surgical navigation;Phototherapy;AIE probe

摘要: Information and communications technology (ICT) investment is beneficial for achieving economic growth within a low carbon system, as the substitution or complementation of ICT to energy offset increased carbon emissions. Based on Chinese provincial panel data during 2000-2018, we incorporate ICT capital as a separate factor to the trans-log production function and identify factor substitution to study ICT's carbon reduction effects.

摘要: This paper investigates trends in intangibles investment since the onset of the COVID-19 pandemic in the United Kingdom. Responses from an online survey show that investment in R&D has dropped substantially for many firms but that over 40% of firms increased their ICT investment, which is likely to reflect the need to facilitate remote working and customer engagement. Industry is a major predictor of the change in intangibles investment. This is consistent with expectations in light of the diffe关键词: COVID-19;intangibles investment;R&D;ICT;D22;L20;O32
