“…In a soil system, the bioavailability, transport, fate and toxicity of nanoparticles are governed by soil factors such as organic matter, soil type, pH and moisture contents because these factors induce a series of changes in NP chemistry such as agglomeration, aggregation, dissolution and biotransformation [ 186 , 187 ]. Nanoparticles adsorbed firstly by the root system can be translocated to the aerial portion where they start accumulating in cellular or subcellular organelles [ 188 ].…”

The advancement in nanotechnology has enabled a significant expansion in agricultural production. Agri-nanotechnology is an emerging discipline where nanotechnological methods provide diverse nanomaterials (NMs) such as nanopesticides, nanoherbicides, nanofertilizers and different nanoforms of agrochemicals for agricultural management. Applications of nanofabricated products can potentially improve the shelf life, stability, bioavailability, safety and environmental sustainability of active ingredients for sustained release. Nanoscale modification of bulk or surface properties bears tremendous potential for effective enhancement of agricultural productivity. As NMs improve the tolerance mechanisms of the plants under stressful conditions, they are considered as effective and promising tools to overcome the constraints in sustainable agricultural production. For their exceptional qualities and usages, nano-enabled products are developed and enforced, along with agriculture, in diverse sectors. The rampant usage of NMs increases their release into the environment. Once incorporated into the environment, NMs may threaten the stability and function of biological systems. Nanotechnology is a newly emerging technology, so the evaluation of the associated environmental risk is pivotal. This review emphasizes the current approach to NMs synthesis, their application in agriculture, interaction with plant-soil microbes and environmental challenges to address future applications in maintaining a sustainable environment.

“…Untuk memastikan mesin dalam kondisi baik dan optimal saat digunakan, dilakukan pemantauan pelumasan. Kualitas sistem pelumasan yang baik juga dapat membuat mesin menjadi awet dan kinerja mesin lebih baik (Ogunkunle et al 2020). Operasi dasar sistem pelumasan adalah menyemprotkan pelumas pada bagian-bagian mesin yang bergerak yang bersentuhan satu sama lain selama penyalaan.…”

Salah satu sistem mekanisme yang mengontrol dan mendistribusikan oli pelumas ke komponen mesin yang berputar adalah sistem pelumasan. Bagian-bagian mesin yang bergesekan satu sama lain rentan terhadap keausan, yang dapat dihindari atau dikurangi dengan pelumasan. Operasi dasar sistem pelumasan adalah menyemprotkan pelumas pada bagian-bagian mesin yang bergerak yang bersentuhan satu sama lain selama penyalaan.Mesin frais merupakan salah satu mesin yang memiliki sistem pelumasan. Pada mesin frais, sistem pelumasan berada pada meja mesin yang bisa bergerak dalam sumbu X, Y dan Z. Pelumasan meja mesin frais perlu dilakukan setiap hari saat mesin akan digunakan. Menurut standar umum mesin frais, pelumasan dilakukan dengan cara menarik tuas pompa pelumas sebanyak empat kali. Namun, karena sistem pelumasan dilakukan secara manual oleh operator, hal tersebut terkadang terlupakan oleh operator. Melihat hal tersebut, peneliti melakukan modifikasi sistem pelumasan yang bertujuan supaya bagian-bagian mesin yang mengalami contact sliding dapat beroperasi dengan otomatis. Metode penelitian ini dengan cara memodifikasi sistem pelumasan manual yang telah ada pada mesin menjadi otomatis yang dikontrol melalui arduino uno dan digerakkan oleh motor stepper. Pada saat pompa pelumas terhubung arus listrik, secara otomatis pompa akan memompa sebanyak empat kali.Motor akan berhenti berputar setelah selesai memompa. Sehingga prototype yang dibuat mampu bekerja pada mekanisme sistem pelumasan mesin frais konvensional secara otomatis menyemprotkan 10ml oli.

“…Many factors such as heteroaggregation and soil organic matter (SOM) affect the extraction of AgCNPs in soils and sediments. − Hence, it is fundamental and necessary to introduce suitable extraction reagents to extract AgCNPs from the soil matrix before separation, identification, and quantitation. Extraction with surfactants like Triton X-114 has been shown to extract gold NPs from soil, but there are disadvantages such as relatively complicated operation process and difficult control of cloud point temperature .…”

The potential risk of various silver-containing nanoparticles (AgCNPs) in soils is related to the concentration, size, and speciation, but their determination remains a great challenge. Herein, we developed an effective method for determining the particle number, size, and species of dominant AgCNPs in soils, including nanoparticles of silver (Ag NPs), silver chloride (AgCl NPs), and silver sulfide (Ag 2 S NPs). By ultrasonication wand-assisted tetrasodium pyrophosphate extraction, these AgCNPs were extracted efficiently from soils. Then, multistep selective dissolution of Ag NPs, AgCl NPs, and whole Ag NPs/AgCl NPs/Ag 2 S NPs was achieved by 1% (v/v) H 2 O 2 , 5% (v/v) NH 3 •H 2 O, and 10 mM thiourea in 2% (v/v) acetic acid, respectively. Finally, the particle number concentration and size distribution of AgCNPs in the extracts and the remaining AgCNP particle number concentration after each dissolution were determined by single-particle inductively coupled plasma mass spectroscopy for speciation of the dominant AgCNPs. AgCNPs were detected in all five soil samples with the concentrations of 0.23−8.00 × 10 7 particles/g and sizes of 16−110 nm. Ag 2 S NPs were the main form of AgCNPs in the examined soils with the percentage range of 53.98−69.19%, followed by AgCl NPs (11.42−23.31%) and Ag NPs (7.78−16.19%). Our method offers a new approach for evaluating the occurrence and potential risk of AgCNPs in environmental soils.
