“…The work function of MoO 3 was found to be 7.58 eV, which is in good agreement with the literature value [46]. Meanwhile, the work function of Ti 3 C 2 T x -30 MXene (which was already determined in our previous work) was 3.78 eV [37]. The work functions for MM-10 and MM-20 were calculated to be 6.91 eV, and 6.75 eV, respectively.…”

“…The synthesis of Ti 3 C 2 T x -30 MXene was carried out as described in our previous work [37]. For that, 1 gm of Ti 3 AlC 2 was subjected to 20 ml of 30 wt% HF acid [37]. After this etching process, centrifugation and vacuum drying were employed.…”

“…We have further enhanced the sensing response by embracing two more techniques. Firstly, as published in our previous work, we have used Ti 3 C 2 T x with optimized −O, and an −OH surface termination group using 30% HF as an etchant acid to increase the interaction of ammonia molecules [37]. Thus, it is named Ti 3 C 2 T x -30.…”

MXene Ti3C2Tx (with 30% HF-etched, named Ti3C2Tx-30) plays a pivotal role in the substantial enhancement of the structural modification of molybdenum trioxide (MoO3). Additionally, as the surface MoO3 molecules come in contact with reducing gas moieties, they actively participate in gas sensing at room temperature. The percentage of Ti3C2Tx-30 in the MoO3 matrix was varied as 10%, 20%, and 40%, denoted as MM-10, MM-20, and MM-40, respectively. Structural analysis confirmed the composition of the basic elements, and evolution of TiO2 at higher percentage of Ti3C2Tx-30. Spectroscopy analysis shows the interactions between Ti3C2Tx-30 and MoO3, showcasing work functions of 6.91 eV, 6.75 eV, and 7.21 eV for MM-10, MM-20, and MM-40, respectively, confirming the MM-20 to be an optimum composition. When the samples were exposed to ammonia gas, MM-20 showed high response (93% for 100 ppm) at room temperature, with the response time ~ 10 s. As compared to bare MoO3 these samples showed ten-fold improvement. The excess electrons on the surface of Ti3C2Tx-30 facilitate the formation of O2- species, which also provides stability to the, otherwise-highly-reactive, MXene surface. These species actively react with ammonia molecules in the presence of adsorbed MoO3, thereby changing the resistance of the system. This can be a significant step towards imparting high gas sensitivity to metal oxides at room temperature via incorporation of optimum percentage of optimised Ti3C2Tx.

Agreement as law for the parties who make it. Indonesia as a rule of law country, reflects every behavior of society based on positive law in Indonesia. The work agreement can be terminated because the rights and obligations between the entrepreneur and the worker or laborer must not conflict with company regulations, collective work agreements and other applicable laws and regulations. This has been agreed and signed and cannot be withdrawn or changed except with the agreement of the parties. Apart from that, this also applies in the economic (business) sector, especially for actors involved in agreements with a company. This research aims to find out the interpretation of the Certain Time Work Agreement (PKWT) based on Article 8 Paragraph (1) of Government Regulation Number 35 of 2021 concerning certain time work agreements, outsourcing, work time and rest time, and termination of employment relations. This research uses juridical-normative legal research. The research results show that the PKWT regulations with a maximum period of 3 (three) years have been removed and PKWT workers will be replaced for no more than 5 (five) years. This includes the extension period as regulated in Government Regulations. If a PKWT worker exceeds the specified time period, then by law it will change to an Indefinite Time Work Agreement (PKWTT).

The rapid expansion of industrialization has resulted in the release of multiple ecological contaminants in gaseous, liquid, and solid forms, which pose significant environmental risks to many different ecosystems. The efficient and cost‐effective removal of these environmental pollutants has attracted global attention. This growing concern has prompted the synthesis and optimization of nanomaterials and their application as potential pollutant removal. In this context, MXene is considered an outstanding photocatalytic candidate due to its unique physicochemical and mechanical properties, which include high specific surface area, physiological compatibility, and robust electrodynamics. This review highlights recent advances in shaping titanium carbide (Ti3C2Tx) MXenes, emphasizing the importance of termination groups to boost photoactivity and product selectivity, with a primary focus on engineering aspects. First, a broad overview of Ti3C2Tx MXene is provided, delving into its catalytic properties and the formation of surface termination groups to establish a comprehensive understanding of its fundamental catalytic structure. Subsequently, the effects of engineering the morphology of Ti3C2Tx MXene into different structures, such as two‐dimensional (2D) accordion‐like forms, monolayers, hierarchies, quantum dots, and nanotubes. Finally, a concise overview of the removal of different environmental pollutants is presented, and the forthcoming challenges, along with their prospective outlooks, are delineated.
