How do energy price, energy-saving policies, and crisis affect energy-saving behavior?

In order to reduce CO2 emissions into the environment, energy conservation is considered a long-term strategy. To encourage people to save energy, the government may need to implement certain policies. Vietnam is a developing country dependent on fossil fuels and heavily affected by climate change.

Assembly of Functionalized Organic Fragments via Reductive Activation and (Cross)-Coupling of CH, CO, CO and/or H Using a Magnesium-Dinitrogen Complex.

Reactions of 1,2-dimagnesioethane compound [{K(NON)Mg}(μ-CH)] (NON = 4,5-bis(2,4,6-tricyclohexylanilido)-2,7-diethyl-9,9-dimethyl-xanthene), formed by the two-electron reduction of ethene with a dimagnesium/dipotassium complex of reduced N, viz. [{K(NON)Mg}(μ-N)], with CO and CO have been explored. In the case of the reaction with CO, cross-coupling of the reduced ethene fragment with two molecules of CO gave a heterobimetallic complex of the parent cyclobutenediolate dianion, [{K(NON)Mg}(μ-OCH)], which when exposed to THF gave adduct [{K(NON)Mg}(μ-OCH)(THF)].

Optimizing adsorption and photocatalysis for tetracycline and sulfamethoxazole removal: the role of Ag and NH in Bi-MOF derivatives.

This study focuses on the synthesis, characterization, and evaluation of the photocatalytic efficiency of bismuth-based metal-organic frameworks (Bi-MOFs) and their derivatives, specifically Ag/Bi-MOF and NH /Ag/Bi-MOF, in the degradation of tetracycline (TC) and sulfamethoxazole (SMX) under visible light irradiation. Bi-MOFs are promising photocatalysts due to their large surface area, tunable porosity, and unique electronic properties that are favorable for visible light absorption. In this study, Bi-MOFs were synthesized using a solvothermal method, with the incorporation of silver (Ag) and ammonium (NH ) ions to enhance their photocatalytic performance.

Lignin nano/micro-particles from agricultural biomasses: Developing direct precipitation for integrated biorefinery.

The state-of-the-art, simple and scalable methods for lignin micro-/nano-particles recovery from agricultural biomasses were evaluated in this review. Being non-wood biomasses, these materials can be easily fibrillated, supporting the usage of mild soda or organic solvent pretreatment. Different approaches in particle recovery were compared to conclude that the bottom-up approach facilitates smaller particles towards the nano-size range whereas mechanical treatment can act as a supporting method to increase uniformity and reduce particle sizes after bottom-up precipitation.

Understanding gastric metastasis of small cell lung carcinoma: Insights from case reports and clinical implications.

Small cell lung cancer (SCLC) is a common type of primary lung cancer that contributes to approximately 15% of cases. It is closely associated with tobacco risk factors. It is also known as a type of lung cancer that has a high mortality rate within a short time due to its rapid growth rate (with tumor doubling time of 30 days) and its tendency to metastasize early in the disease process.

Recurrence Rate and Associated Factors of Primary Fallopian Tube Carcinoma in the South of Vietnam.

Objectives: This study aimed to determine the recurrence rate and related risk factors of primary fallopian tube cancer (PFTC).

Digitally-defined ultrathin transparent wireless sensor network for room-scale imperceptible ambient intelligence.

Wireless and battery-free radio-frequency (RF) sensors can be used to create physical spaces that ambiently sense and respond to human activities. Making such sensors ultra-flexible and transparent is important to preserve the aesthetics of living environments, accommodate daily activities, and functionally integrate with objects. However, existing RF sensors are unable to simultaneously achieve high transparency, flexibility, and the electrical conductivity required for remote room-scale operation.

War dead, trauma, and care: the differential reintegration of Vietnamese former combatants.

This paper explores how Vietnamese former combatants navigate and contest the infrastructure of care and recognition (or lack thereof) for veterans, their families, and the war dead in postwar Vietnam. It examines efforts by veterans to establish their socio-political standing through acts of claim-making, including spiritual care for the dead. We argue that through these acts of claim-making, veterans forge an alternative modality of veteranhood based not simply on state-recognised war contributions, but also on moral commitments to social justice and care for the fallen and their bereaved families in the postwar period.

Preparation strategies, properties highlights, and emerging applications across environmental, biological, and energy industries of silver-loaded graphitic carbon nitride: A critical review.

In light of escalating environmental pollution and tremendous energy shortage, the development of multifunctional materials with diverse applications across biomedical and energy production platforms has become imperative. Among this domain, nanostructured heterogeneous composites based on semiconductors are exclusively promising owing to their distinct configurations. Notably, graphitic carbon nitride (g-CN (CN)) has drawn substantial interest as a sustainable candidate with surface functionality, electron-rich nature, and interconnected conjugation system along the polymeric matrix.

Effect of pore structure in bismuth metal-organic framework nanorod derivatives on adsorption and organic pollutant degradation.

This study explores the synthesis, characterization, and photocatalytic properties of bismuth metal-organic framework (Bi-MOF) nanorods and their derivatives such as Ag/Bi-MOF and Ag/BiO. Bi-MOF nanorods exhibit significant photocatalytic activity under visible light, with the addition of silver (Ag) enhancing electron-hole pair separation and reducing their recombination. This leads to improved photocatalytic performance, particularly in the degradation of organic pollutants such as Rhodamine B (RhB) and Methylene Blue (MB).

11-Azaartemisinin derivatives bearing halogenated aromatic moieties: Potent anticancer agents with high tumor selectivity.

While artemisinin and its derivatives, including 11-azaartemisinin-based compounds, have shown promising anticancer activity, the integration of halogens into aromatic structures can amplify drug potency, metabolic stability, and selectivity. Herein, we present the synthesis of new novel 11-azaartemisinin derivatives bearing halogenated aromatic moieties connected via 1,2,3-triazole bridges and evaluate their anticancer activities against three human tumor cell lines: epidermoid carcinoma (KB), hepatocellular carcinoma (HepG2), and human lung adenocarcinoma (A549). Among the synthesized compounds, six of them (8c-h) displayed good to excellent antiproliferative activity in the low micromolar range across all three human cancer cell lines.

An isolable stannaimine and its cycloaddition/metathesis reactions with carbon dioxide.

An N-heterocyclic stannylene :Sn(NON) (NON = [O(SiMeNAd)], Ad = 1-adamantyl), reacts rapidly with 2,4,6-tricyclohexylphenyl azide (TCHP)N, affording a stannaimine, (NON)SnN(TCHP). Solutions of (NON)SnN(TCHP) react immediately with carbon dioxide (CO) to give a [2+2]-cycloaddition product, which, upon heating, subsequently engages in a metathesis process to give [Sn(NON)(μ-O)] and the bulky isocyanate, (TCHP)NCO.
